    [0002] MOLD FOR THE MANUFACTURE OF THREE-DIMENSIONAL ITEMS
    [0003]
    [0004] Field of the Invention
    [0005] The present invention relates to a mold for the manufacture of three-dimensional articles, especially flexible wall, such as footwear, bags, clothing, etc., and in general all types of articles that are limited by a flexible external wall composed based on laminar pieces, flexible in nature, which are joined together by their opposite edges. As well as, for the manufacture of flexible wall articles provided with an internal lining, or comprising a wall or core of a semi-rigid nature, such as, for example, seat furniture, vehicle dashboards, etc.
    [0006]
    [0007] The present invention allows the implementation, both in large-scale productions and in reduced games, of the new 3D Bonding technologies, 3D Printing, among others in Industry 4.0, in order to manufacture flexibly and intelligently, with low costs and close of the consumer.
    [0008]
    [0009] Background of the Invention
    [0010] Traditionally, the articles of the indicated type have been manufactured by means of the union by sewing without injection of the laminar pieces that compose them. Whose seams require the realization of holes that, in turn, constitute water penetration routes that force the use of linings based on special membranes, internal sealing tapes, etc. for the manufacture of waterproof products. In the particular case of footwear, once the laminar pieces have been sewn, it is also necessary to carry out a subsequent process of gluing the sole on said laminar pieces. Sewing the pieces together before putting the sole on is known as “aparado”. All this involves a high amount of labor and process time, as well as an increase in production costs. Furthermore, it also implies limitations in the design and comfort of said articles, as well as a loss of their stability.
    [0011]
    [0012] Traditional factories often require:
    [0013] - a separation of complex processes into a large number of basic tasks, sequenced in series within the production chain;
    [0014] - availability of machines of varying complexity to support operators in the execution of the different process stages; Y
    [0015] - a specific distribution of the jobs for the execution of the manufacturing tasks, according to the main phases of the manufacturing processes and to the systems used to transport raw materials, components, finished or semi-finished products, from one place to another in the factory.
    [0016]
    [0017] In summary, all this implies:
    [0018] - the widespread presence of abundant workers in the different process areas;
    [0019] - manual supervision and control of a large number of operations;
    [0020] - the use of a large number of classic mechanical conveyor belts or belts, of great rigidity and with little or no flexibility to adapt to changes and / or new procedures; Y
    [0021] - the classic compartmentalized organization, made up of units and warehouses, in which the process units are fed by the stock of materials stored in inbound warehouses, and from which they are subsequently shipped as semi-finished products to the outbound warehouses.
    [0022]
    [0023] On the other hand, the so-called direct-cut injection processes are also currently known, in which once the pieces are sewn a component of the article is formed by injection. In the particular case of footwear, it consists of manufacturing a shoe cut with seams and closing it on the ground with a fabric, according to a sewing technique called “strobel ', which configures a sock. Said sock, once it is turned on, is fitted in a last that is connected to an injection unit, which, in turn, has two lateral sole molds that are closed by hugging the last with the sock. This produces a closure that allows to keep the injected or cast polymer in the volume that constitutes the sole.
    [0024]
    [0025] The direct injection cutting processes are very useful because they reduce the cost of labor in the sole assembly and gluing processes. However, they do not alter the traditional process of aparado that, in terms of labor, they represent more than 50% of the total cost of the product. For this reason, although they present savings, they do not offset the cost of manufacturing the injection molds. Additionally, direct injection molds present the following problems.
    [0026]
    [0027] Firstly, direct injection molds are generally composed of various machined metal parts. In the case of footwear, to make a model, several sizes of molds are missing, with their corresponding right and left feet, therefore the cost of manufacturing a series of molds is very expensive. This has generated that despite being beneficial, direct injection can only be used for production batches much higher than the average, which has been a great barrier for this technology for decades. This added to that the fashion is more and more rapidly changing, makes short production runs more necessary, thus generating more lack of competitiveness of the system. In conclusion, if molds were substantially cheaper, direct injection would rapidly expand in the market and other similar processes.
    [0028]
    [0029] In the specific case of direct injection molds for two injections with two polymers of different characteristics, they are made up of the following parts:
    [0030] - Aluminum last where the cut is shod and which is bolted to the machine, and which also usually rotates to place a second last.
    [0031] - Aluminum last with first-contact foot contact with the ground ( drummy plate) that is also bolted to the machine.
    [0032] - Two internal and external side molds that draw the sole on the sides and close with the cut ( side rings).
    [0033] - Piston mold that rises and falls to allow the entry and closure of polymer and the injection point. In turn, it also has the tread pattern ( bottom mold).
    [0034]
    [0035] Since both lasts are attached to the machine, and the side rings are also attached to the machine independently, it is very difficult to obtain exact centering accuracy with respect to the bottom of the mold. it takes a long time to calibrate between the lasts and the rest of the mold components.
    [0036] The fact of having to hold several left and right molds in different sizes, implies the use of carousel-type machinery of large dimensions that generally hold between 24 and 36 stations. These machines are expensive, occupy a large space, have a great weight and consume a lot of electrical energy. Aspects that further limit the use of this technology.
    [0037]
    [0038] Direct injection molds generally close against cutting with the aluminum surface and, in other cases, with a dressing made of a softer material, such as Teflon, which is inserted into the slot manually. This tries to compensate for irregularities due to the overlapping pieces of the upper that are the cause of polyurethane flows to the outside of the sole, between the skin and the mold. However, this deformation is not sufficient to compensate for these irregularities and leaks often exist.
    [0039]
    [0040] On the other hand, direct injection soles have a parting line at the front and back of the shoe, due to the effect of the union between the side rings. This detail noticeably deteriorates in aesthetics compared to other processes such as assembling and gluing where the soles do not have said “parting line”. This occurs because the molds to configure the midsole close with two half sections that, although the mold is well adjusted, also always leave a visible line of closure in the midsole of the shoe.
    [0041]
    [0042] During the production process mold release agents are applied sprayed against the aluminum mold in order to prevent the polyurethane from adhering to the surface of the mold. The problems in this case are several. On the one hand, they are not positive for the environment, and on the other hand, these release agents create a surface layer in the mold that acts on the chemical reaction, preventing it from sticking, but at the same time destroying the superficial skin that generates the polyurethane reaction that is usually be smooth and bubble-free. On the contrary, the agents destroy that smooth layer, and the bubbles resulting from the light polyurethane expansion reaction end up being visible on the outside, thus generating a low surface quality appearance.
    [0043] Mainly, the costs of direct injection molds are high because they consist of several pieces of aluminum, generally mechanized by numerical control. These molds are designed to catch the cut on the last, by means of an aluminum piece that configures the outer face of the sole and another aluminum piece that configures the inner face of the sole of the shoe. In addition, they have a piece attached to a piston at the bottom that has the tread design and two lasts (one metal with a tread pattern that serves to configure the injection of a thin skate, and the other last is the one that allows you to sheathe the shoe).
    [0044]
    [0045] Another drawback from the design point of view is that, with aluminum molds, the soles are usually designed considering the counter-exits of the piece according to the mold opening directions and considering the deformation capacity of the injected material to be able to bend and exit. . This represents a design limitation problem since it is considered that it depends only on the deformation of the sole when exiting and no deformation of the mold as it is made of aluminum.
    [0046]
    [0047] Another drawback from the aesthetic point of view is that, with direct injection molds, the pressure exerted on the cutting material by the aluminum mold usually marks the cutting materials as skin, due to the high pressure and hardness of the mold. This pressure in turn is usually several tons to be able to compress superimposed skins and avoid the overflow of injected material that escapes between the surface of the cut and the mold.
    [0048]
    [0049] Finally, these direct injection systems are rotating carousel or banana style to place various sizes of shoes, so that while some prepare, other shoes find the necessary time inside the mold for polymer curing.
    [0050]
    [0051] On the other hand, other significant drawbacks of this type of mold, related to its permanent connection to injection machines, are summarized below: - The assembly and / or screwing of the different components of the mold into the machine implies a considerable time of work, which is repeated every time a different model and / or article has to be manufactured. In addition, they require its connection to other power elements (wiring, air suction ducts, etc.) and / or operation (heaters, mechanical components of the machine, etc.) of external type.
    [0052] - Half-manufactured articles must remain in the mold until they are ready to face a next stage of the manufacturing process (for example, a second stage injection, mold release, etc.). In turn, since the mold is linked to the machine and permanently attached to it until its change occurs, the machine is unusable until the necessary conditions are met (for example, once the necessary curing time of the half-manufactured item).
    [0053] - Most of the pieces that make up these molds are designed for specific models and / or sizes that are incompatible with other models and / or sizes.
    [0054] - The pressures exerted between mold and counter-mold (last) during injection are considerable.
    [0055] - There is limited control of the condition of the articles in process and / or of the physical conditions that occur within the mold at any time, as well as low traceability of the mold components.
    [0056]
    [0057] The present invention solves the aforementioned problems by means of an independent mold that is kept closed without being connected to a machine, whose configuration allows its mobility throughout the process chain of a manufacturing plant (for example, from its storage until the mold is removed from the article manufactured inside and subsequent reuse of the mold). Allowing to know the position of the mold at any time of the process, as well as the state of the article contained within it and the information related to it, locally and / or remotely. And use these smart systems to incorporate the mold into the process line and automatically direct it to the various workstations. Where said mold has a greater number of standard and interchangeable components that are easy to manufacture and low cost, compatible with different models and / or sizes of the articles to be manufactured, and which also allow it to work at lower pressures and increase its efficiency. In which said mold is not permanently attached to a certain machine in the process chain, but can move freely along said process chain to work on other machines configured to perform different processes, and / or address the warehouse with a half-manufactured product in its interior until the necessary conditions are met in it to face a next stage of the manufacturing procedure.
    [0058]
    [0059] Likewise, it should be noted that the mold of the present invention is applicable both in the processes of direct injection to the cut described above, and in the manufacture of three-dimensional articles with flexible walls by means of the procedure described in document WO2018109242A1. In said procedure, the three-dimensional flexible wall articles are manufactured by means of a mold and a counter-mold between which a volume corresponding to that of the article to be obtained is delimited. The article is usually composed of one or more flexible laminar pieces that are mounted on a flexible template that has multiple functionalities and that is arranged on the internal surface of the mold, the laminar pieces being joined together by means of an adherent material that is injected in a fluid state. through a network of ducts limited between mold, flexible template and facing edges of laminar pieces.
    [0060]
    [0061] The present invention allows the creation of new smart factories that, unlike traditional factories, have the following advantages: - They are capable of making very short production runs (for example, a single pair of shoes) according to requirements. from a particular customer;
    [0062] - they are capable of making their decisions by artificial intelligence, having various decision-making points, both at the beginning of the entry line and at the exit of molds into the warehouse;
    [0063] - they have the ability to connect to the molds remotely to know their status;
    [0064] - they are able to use augmented reality to see in situ and virtually what is happening in production;
    [0065] - they have collaborative robots to help in repetitive tasks, such as putting pieces in the mold; Y
    [0066] - They have transport robots that send parts from processes prior to the mold injection section.
    [0067]
    [0068] Description of the Invention
    [0069] The mold for manufacturing three-dimensional articles of the present invention comprises:
    [0070] - a body that defines an internal surface, which can be composed of one or more pieces;
    [0071] - a lid configured to close said body; Y
    [0072] - own closing and opening means configured to hold the body and the lid together during the movement of said mold.
    [0073]
    [0074] This configuration allows the mold to be kept closed without the need to be connected or fixed to a machine. This gives it the advantage of being able to move to any other point in the manufacturing plant or process line, for example, the area of injectors, mold warehouses, work stations for the placement of sheet parts, mold release areas, etc. With the additional advantage that the mold, in addition to being empty, can be moved from one area to another with the article to be manufactured inside. This allows the machines in the process chain to be freed so that they can be used by other molds, while the half-manufactured articles have just met the necessary conditions (curing time, resistance, pressure, temperature, etc.) within the machine itself. mold, and in any other place of the factory, to face the following stages of the manufacturing procedure.
    [0075]
    [0076] Preferably, the mold comprises an elastically deformable insole disposed between the body and the lid, for example, made of silicone, which fits on said internal surface and is configured to receive one or more laminar pieces of an article to be manufactured. As silicone is a chemically resistant material, it makes it possible to dispense with release agents during the production process.
    [0077]
    [0078] Preferably, the mold comprises a counter-mold, or last in the case of footwear, that occupies a defined volume between the body and the cover, and more preferably, between the insole and the cover, which is configured to press the laminar pieces against the template when the body and the cover are together. This allows that, once the injection of the plastic fluid that joins the facing edges of the laminar pieces is carried out, or prior to the injection process in the case of laminar pieces that are sewn, the last maintains the necessary pressure on said laminar pieces during the curing time, or at any other time, to ensure that the pieces do not separate. Thus, the mold can be moved to other areas of the production line while curing is carried out inside, the body being and the cover joined together and pressing the last that is snug between them.
    [0079]
    [0080] Another notable advantage of having the last placed inside the mold is that it is perfectly centered, unlike the injection molds known in the state of the art, in which centering problems usually occur due to the fact that the mold parts and the last they are attached to the machine, as described in the background section.
    [0081]
    [0082] Preferably, the body comprises a mold release hole configured to allow the passage of a thrust element or external mold for the extraction of the last by the thrust exerted on it by said external mold element. In this way, once the article is manufactured, the last can be extracted from it.
    [0083]
    [0084] Preferably, the body comprises:
    [0085] - a fixed part on which the mold is supported, formed by one or more pieces; and - an interchangeable part in which the internal surface of the body is defined, and which is configured to be removably mounted on the fixed part. Where the interchangeable part can be formed by one or more pieces, interchangeable together or individually.
    [0086]
    [0087] This makes it possible to standardize the components of the mold, so that the fixed part, or chassis, acts as a support element and / or structural element of the mold, regardless of the model and / or size of the article to be manufactured, therefore said part Fixed is common for a large number of articles, as well as for a large number of models and / or sizes thereof. On the other hand, the interchangeable part is what determines the shape, size and / or design characteristics of each item to be manufactured. Therefore, with a smaller number of components and / or mold parts, a greater number of different articles can be manufactured. Likewise, the fixed part and the interchangeable part have complementary shapes that facilitate their assembly and replacement in a quick and simple way.
    [0088]
    [0089] According to a particular embodiment, the cover can also comprise one or more interchangeable parts, defining other shapes and / or surfaces of the article to manufacture in order to further standardize the mold components.
    [0090]
    [0091] Preferably, the fixed part is made of metallic material, for example aluminum, to offer the mold the robustness and resistance necessary to carry out the functions described above.
    [0092]
    [0093] The interchangeable part can also be metallic, although it is preferably made of plastic material, to carry out a triple function:
    [0094] - Facilitate the manufacture of said interchangeable part with more economical materials, allowing its rapid and economic manufacture using 3D printing techniques.
    [0095] - Offer a support base for the laminar pieces, so that when they receive pressure from the last on the elastically deformable insole, pressed in turn by the cover when closing against the body, said deformity exerts an opposite pressure, or in Opposite direction, perpendicular to the flexible pieces, guaranteeing an efficient closure during the passage of the fluid plastic material to avoid spillage (overflow) out of the mold.
    [0096] - Use rigid metallic materials, such as aluminum, in the fixed part of the body and in the cover, combined with other materials in the interchangeable part of the body and / or in the template of elastically deformable material. So, as the support material is softer than aluminum, a more efficient closure is generated that allows to cover irregularities in the surface of the product or article to be manufactured, or even two overlapping cutting pieces. This type of closure is softer and does not require such high closing pressures, because instead of deforming the article to avoid spillage, what is deformed is part of the mold. The closing pressures can drop to a ratio of 10 to 1 compared to those received by non-transportable aluminum molds that are attached to existing machines, thus making it possible to manufacture machinery for the manipulation of this type of molds that is smaller and cheaper .
    [0097]
    [0098] Preferably, the body comprises:
    [0099] - one or more vacuum chambers that communicate with a plurality of suction holes that reach the internal surface of the body; Y
    [0100] - one or more extraction nozzles that allow the extraction of air from the chamber of emptiness.
    [0101]
    [0102] In turn, the template includes:
    [0103] - a plurality of holes in communication with the suction holes, configured to attract against said template one or more laminar pieces of the article to be manufactured when the air is extracted from the vacuum chamber.
    [0104]
    [0105] This facilitates the work of placing the laminar pieces inside the mold, given that these pieces remain attracted to the template as the operator places them in an orderly manner, without having to glue them onto said template by using adhesive products.
    [0106]
    [0107] This same configuration can also be carried out on the counter-mold, or last in the case of footwear, for the same purpose. In other words, said counter-mold or last may also comprise a vacuum chamber in communication with a plurality of suction holes that reach the surface of one or more of its faces. So, when placing the laminar pieces on said faces, the pieces remain attracted against them due to the extraction of air from the vacuum chamber, while the placement process of the pieces lasts. Therefore, it is not necessary to glue them onto the counter-mold or last through the use of adherent products, nor is it necessary to cover the last with a sock sewn as is traditional in direct injection processes.
    [0108]
    [0109] Preferably, the body comprises:
    [0110] - a first lateral piece defining a first portion of the internal surface on which the template fits; Y
    [0111] - a second lateral piece defining a second portion of the internal surface on which the template fits;
    [0112] where the first side piece and the second side piece are joined together when the cover is attached to the body, and configured to move in opposite directions once the cover is removed from the body. The first side piece and the second side piece can also remain attached without the need for the cover to be attached. Also, on the lateral parts the elastically deformable insole is positioned, so that to separate them it is necessary to overcome the resistance to the elongation of said template.
    [0113]
    [0114] This allows the mold to be opened laterally, once the lateral pieces have been arranged on the insole, in turn allowing the introduction of the last. On the other hand, to prevent the vacuum inside the mold from being lost in such a situation, a fact that could cause the side pieces to be displaced, preferably, the first side piece and the second side piece are jointly covered by an elastic cover configured to prevent external air from entering when both side pieces are separated. More specifically, the elastically deformable insole fitted on the internal surface portions of the body, in combination with the elastic cover, also deformable, allow said body to remain watertight despite the gap between the first side piece and the second piece. side.
    [0115]
    [0116] To increase the slip and / or mobility of the mold along the process line, said elastic sheath may comprise, on its external lower face, or support face, one or more metal plates to avoid friction that would cause the plastic material of the cover over other transport elements (conveyor belts or bands, etc.) and / or machinery (work stations, etc.).
    [0117]
    [0118] To allow the interaction of drives and / or external elements with the mold, the elastic cover also comprises a plurality of openings or windows of different shapes and sizes to make visible functional and / or connecting elements thereof such as, for example; own closing and opening means, lateral closing and opening means, the vacuum chamber air extraction nozzle, electrical connectors, etc.
    [0119]
    [0120] Preferably, the mold comprises at least one or more electric heaters arranged within the body. Preferably, said heaters are thermally isolated from the outside of said body by the elastic cover. This allows the heat inside the mold to be retained, so that electric heaters with lower power and electrical consumption can be used. Specifically, the fact that the mold is covered by a material with a lower thermal conductivity than aluminum allows keeping the mold tempered and, thus, reducing energy.
    [0121] The electric heater can be wired to the production line, or powered electrically by the mold itself using batteries.
    [0122]
    [0123] Preferably, the mold comprises lateral opening and closing means configured to hold the first lateral piece and the second lateral piece together, and to allow a subsequent lateral separation thereof, formed by:
    [0124] - at least one lateral latch running through a lateral hole in the body, at the end of which it has a lateral closing element configured to connect the first lateral part to the second lateral part; Y
    [0125] - at least one lower drive that runs through a lower hole in the body, at the end of which it has a lateral opening element configured to unlock the closing element of the lateral latch.
    [0126]
    [0127] The described configuration increases the accessibility of the lateral closing and opening means, so that they can be easily actuated externally acting on the lateral faces of the mold and on the lower face thereof.
    [0128]
    [0129] Preferably, the lid comprises:
    [0130] - a first face defining a first counter-mold associated with a first volume of the article to be manufactured; Y
    [0131] - a second face defining a second counter-mold associated with a second volume of the article to be manufactured;
    [0132] where the cover has a reversible character that allows the body to be closed through the first face or the second face.
    [0133]
    [0134] In this way a reversible cover is obtained that allows a first injection of plastic material through the first face, and a second injection of plastic material through the second face. As a result, the number of mold components can be further reduced, in addition to simplifying the manufacturing process.
    [0135]
    [0136] Preferably, the lid comprises at least a partial covering or sheet of an elastically deformable material, for example, silicone, arranged in one or both counter molds of the first and second face (for example, adhered on one or both of them against -molds). The purpose of this coating is to form shapes and / or additional configurations (channels, holes, contours, etc.) of the product that are added to those already defined by the machining of the counter-molds (for example, additional to the shape and / or configuration of the sole of a sports shoe) . In this way a continuous design around the product can be achieved, in combination with the elastically deformable silicone insole located in the body of the mold. That is, a 360 ° circulation of the polyurethane injected into the mold, taking advantage of the steps and / or channels defined for it in the template and the lining.
    [0137]
    [0138] Own closing and opening means are understood all those that are integrated into the mold itself, or are part of it, and that move together with said mold along the production line to keep the lid closed against the body . This, regardless of whether said own closing and opening means require or not other external elements (drives, mechanisms, tools, etc.) to open and / or close the cover with respect to the body.
    [0139]
    [0140] Preferably, the own closing and opening means comprise:
    [0141] - at least one upper latch running through an upper hole that extends from the body to the lid, at the end of which it has an upper closure element configured to connect the body to the lid; Y
    [0142] - at least one blocking element that works in collaboration with the upper closing element; Y
    [0143] - at least one release actuator configured to release the closing element from the blocking element.
    [0144]
    [0145] The described configuration increases the accessibility of the own closing and opening means, so that they can be easily actuated externally, acting, for example, on the lower face thereof. Furthermore, said configuration guarantees a safe and hermetic closing of the mold, capable of withstanding the working pressures that occur within it, for example, during the injection stages of the manufacturing process, without spillage of the fluid material.
    [0146]
    [0147] According to a particular embodiment, the closing and opening means themselves may comprise one or more electromagnets arranged in the mold, configured to electromagnetically join the body and the cover.
    [0148] The mobile and / or transportable nature of the mold of the present invention, which also allows carrying out different stages of the manufacturing process in different work areas and / or machines, makes it convenient to carry out exhaustive control at all times of the position of the mold. , of the information of the article contained within, of certain physical conditions that influence the state of said article during its manufacture, etc. All this, in order to obtain an intelligent manufacturing procedure that allows optimal and efficient management of available resources (machinery, molds, materials and / or components of the article to be manufactured, etc.), in addition to increasing production capacity. of the plant, reduce manufacturing times and simplify costs.
    [0149]
    [0150] For this, preferably, the mold comprises remote identification means configured to transmit mold information by radio frequency to a data network. In this way, the central data system of the manufacturing plant can receive this information and send the corresponding orders to the mold for its operation.
    [0151]
    [0152] Preferably, the mold comprises local identification means configured to transmit mold information by wiring and / or direct connection to an electronic device.
    [0153]
    [0154] Preferably, the mold comprises wireless connection means configured to connect to the Internet and / or to a data network.
    [0155]
    [0156] Preferably, the mold comprises one or more pressure and / or temperature sensors to know the physical conditions inside it.
    [0157]
    [0158] Preferably, the mold is electrically powered from its own power source by means of one or more batteries arranged within it, and / or from an external power source through an electrical connection socket provided therein.

    [0196]
    [0197] Detailed description of the invention
    [0198] As seen in FIGS. 1 and 2, the mold (1) for the manufacture of three-dimensional flexible wall articles of the present invention comprises:
    [0199] - a body (2) defining an internal surface (S 2 ), see FIG. 7;
    [0200] - an elastically deformable insole (3), for example made of silicone (which also has a waterproof character that does not allow air to pass through), which fits on said internal surface (S 2 ) and is configured to receive one or more laminar pieces (L) of an article to be manufactured;
    [0201] - a cover (4) configured to close said body (2), the template (3) being arranged between the body (2) and the cover (4); Y
    [0202] - own closing and opening means (5) configured to hold the body (2) and the cover (4) together during the transport / movement of the mold (1).
    [0203]
    [0204] This configuration allows the mold (1) to be kept closed without the need to be connected or fixed to a machine. This gives it the advantage of being able to move to any other point in the manufacturing plant or process line, see FIG. 13.
    [0205]
    [0206] The body (2) comprises:
    [0207] - a first lateral part (2a) defining a first portion (S 2 a) of the internal surface (S 2 ) on which the template (3) fits; Y
    [0208] - a second lateral piece (2b) defining a second portion (S 2 b) of the internal surface (S 2 ) on which the template (3) fits;
    [0209] where the first side piece (2a) and the second side piece (2b) are joined with each other when the cover (4) is attached to the body (2), and configured to move in opposite directions (d 2 a, d 2 b) once the cover (4) is removed from the body (2). This allows the mold (1) to be opened laterally, once the lateral pieces (L) are arranged on the template (3), in turn allowing the introduction of a counter-mold (6), or last (6) for manufacturing of footwear, see FIG. 9b.
    [0210]
    [0211] On the other hand, to prevent the vacuum inside the mold (1) from being lost in such a situation, a fact that could cause the lateral pieces (L) to be displaced, the first lateral piece (2a) and the second lateral piece (2b) they are jointly covered by an elastic sheath (7) configured to prevent the entry of external air when both side pieces (2a, 2b) are separated. To allow the interaction of drives and / or external elements with the mold (1), the elastic cover (7) also comprises a plurality of openings or windows (71) of different shapes and sizes to make visible functional and / or connection elements the same as, for example; the own closing and opening means (5), the lateral closing and opening means (9), the air extraction nozzle (25) from the vacuum chamber (23), orifices (111) for fluid material, electrical connectors etc.
    [0212]
    [0213] The own closing and opening means (5) are integrated into the mold (1) itself, or are part of it, and move together with said mold (1) along the production line keeping the lid closed ( 4) against the body (2).
    [0214]
    [0215] According to the present example, the own closing and opening means (5) comprise:
    [0216] - a plurality of upper latches (51), one for each corner of the mold (1), where each one of them runs through an upper hole (52) that extends from the body (2) to the cover (4), at which end it has an upper closure element (53) configured to connect the body (2) to the cover (4); Y
    [0217] - at least one blocking element (54) that works in collaboration with the upper closing element (53); Y
    [0218] - at least one release actuator (55) configured to release the closing element (53) from the blocking element (54).
    [0219]
    [0220] According to the present example, each release actuation (55), or key, it comprises an inner spring (not shown), so that when said spring is pressed by means of the release actuation (55), the upper closure (53) of the locking element (54) is released. On the contrary, if no action is taken on the release drive (55), the upper closure (53) remains locked, preventing the cover (4) from opening.
    [0221]
    [0222] The described configuration increases the accessibility of the own closing and opening means (5), so that they can be easily actuated externally, acting, for example, on the contour of the cover (4).
    [0223]
    [0224] FIG. 3 shows a plan view of the mold (1).
    [0225]
    [0226] As seen in FIG. 4, the mold (1) comprises a counter-mold (6), or last (6) for the manufacture of footwear, which occupies a volume (V) defined between the insole (3) and the cap (4), and which it is configured to press the laminar pieces (L) against the template (3) when the body (2) and the cover (4) are joined, see FIG.
    [0227] 9b.
    [0228]
    [0229] The body (2) comprises a release hole (60) configured to allow the passage of an external release element for the extraction of the last (6) by means of the thrust exerted on it by said external release element. In this way, once the article is manufactured, the last (6) can be extracted from it.
    [0230]
    [0231] FIG. 5 shows a bottom view of the mold (1) in which the different elements that allow the interaction of the mold (1) with a machine for handling it can be seen in greater detail.
    [0232]
    [0233] Specifically, the mold (1) comprises four unlocking drives (55) configured to release, each of them, a closing element (53) from the own closing and opening means (5).
    [0234]
    [0235] On the other hand, there are also two lower holes (95) located in the central part that give access to two other lower drives (94) configured to unlock, each of them, a closing element (93) of the closing means Y side opening (9).
    [0236]
    [0237] It is also seen from another point of view the release hole (60) configured to allow the passage of an external release element for the extraction of the last (6), as well as the air extraction nozzles (25) of the chamber vacuum (23).
    [0238]
    [0239] Finally, to increase the slip and / or mobility of the mold (1) along the process line, the elastic sheath (7) comprises on its external lower face, or support face, two metal plates (72) to avoid the friction that the plastic material of the cover would cause on other transport elements (conveyor belts or bands, etc.) and / or machinery (work stations, etc.).
    [0240]
    [0241] FIG. 6 shows a side view of a third exploded view of the mold (1).
    [0242]
    [0243] As seen in FIG. 7, the body (2) comprises:
    [0244] - a fixed part (21) on which the mold (1) is supported; Y
    [0245] - an interchangeable part (22) in which the internal surface (S 2 ) of the body (2) is defined and on which the template (3) is fitted, and which is configured to be removably mounted on the fixed part (21), see FIGS. 9a and 9b.
    [0246]
    [0247] The fixed part (21), or chassis, acts as a support element and / or structural element of the mold, regardless of the model and / or size of the article to be manufactured, so that said fixed part (21) is common for a large number of articles, as well as for a large number of models and / or sizes thereof. On the other hand, the interchangeable part (22) is what determines the shape, size and / or design characteristics of each article to be manufactured. Therefore, with a smaller number of components and / or parts of the mold (1) a greater number of different articles can be manufactured. Likewise, the fixed part (21) and the interchangeable part (22) have complementary shapes that facilitate their assembly and replacement in a quick and simple way.
    [0248]
    [0249] The fixed part (21) is made of metallic material, such as aluminum, while the interchangeable part (22) is made of plastic material that is easily produced by 3D printing.
    [0250] The mold (1) comprises two electric heaters (8) arranged inside the body (2), thermally isolated from the outside of said body (2) by an elastic cover (7).
    [0251]
    [0252] As seen in FIG. 8, the mold (1) comprises lateral closing and opening means (9) configured to hold the first lateral part (2a) and the second lateral part (2b) together, and to allow a subsequent lateral separation thereof, which they are formed by:
    [0253] - at least one lateral latch (91), provided with a first spring (97), which runs through a lateral hole (92) of the body (2), at whose end it has a lateral closing element (93) configured to joining the first side piece (2a) to the second side piece (2b); Y
    [0254] - at least one lower drive (94), provided with a second spring (98), which runs through a lower hole (95) of the body (2), at the end of which it has a lateral opening element (96) configured to unlock the closing element (93) of the side latch (91).
    [0255]
    [0256] The described configuration increases the accessibility of the lateral closing and opening means (9), so that they can be easily actuated externally acting on the lateral faces of the mold (1) and on the lower face thereof.
    [0257]
    [0258] As seen in FIG. 9a and 9b, according to the present example, the own closing and opening means (5) additionally comprise at least one closing spring (56) configured to press the cover (4) against the body (2) when both are joined , FIG 9b.
    [0259]
    [0260] For this, the own closing and opening means (5) comprise at least one rod (57) that has:
    [0261] - an upper end (57s) in which the upper latch (51) is arranged; Y
    [0262] - a lower end (57i) on which the closing spring (56) is arranged;
    [0263] where the closing spring (56) is in a compressed position (56T) when the cover (4) is attached to the body (2) to exert a downward pushing force (F 56 ) against the lower end (57i) of the rod (57).
    [0264] In any case, the presence of the closing springs (56) and the elements associated with them are an optional complement to the closing means (5) previously described, the purpose of which is to offer a greater hold on the cover (4) to the body (2) during the transportation of the mold (1). That is, the own closing and opening means (5) formed by the elements (51, 52, 53, 54, 55) can also function adequately without the presence of the closing springs (56).
    [0265]
    [0266] As seen in FIGS. 10a and 10b, the body (2) comprises:
    [0267] - a vacuum chamber (23) that communicates with a plurality of suction holes (24) that reach the internal surface (S 2 ) of the body (2); Y
    [0268] - an extraction nozzle (25) that allows the extraction of air from the vacuum chamber (23).
    [0269]
    [0270] In turn, the template (3) includes:
    [0271] - a plurality of holes (31) in communication with the suction holes (24), configured to attract against said template (3) one or more laminar pieces (L) of the article to be manufactured when the air is extracted from the vacuum chamber ( 2. 3).
    [0272]
    [0273] As previously stated, the body (2) comprises:
    [0274] - a first lateral part (2a) defining a first portion (S 2 a) of the internal surface (S 2 ) on which the template (3) fits; Y
    [0275] - a second lateral piece (2b) defining a second portion (S 2 b) of the internal surface (S 2 ) on which the template (3) fits;
    [0276] where the first side part (2a) and the second side part (2b) are joined together when the cover (4) is attached to the body (2), and configured to move in opposite directions (d 2 a, d 2 b) once the cover (4) has been removed from the body (2). This allows the mold (1) to be opened laterally, once the lateral pieces (L) have been arranged on the insole (3), in turn allowing the introduction of the last (6), see FIG. 9b.
    [0277]
    [0278] The elastically deformable insole (3) fitted on the internal surface portions (S 2 a, S 2 b) (S 2 ) of the body (2), in combination with the elastic sheath (7), also deformable, allow said body (2) remains watertight despite the gap between the first side piece (2a) and the second side piece (2b).
    [0279] As seen in FIG. 10c, the cover (4) comprises:
    [0280] - a first face (41) defining a first counter-mold (42) associated with a first volume (V 1 ) of the article to be manufactured; Y
    [0281] - a second face (43) defining a second counter-mold (44) associated with a second volume (V 2 ) of the article to be manufactured;
    [0282] where the cover (4) has a reversible character that allows the body (2) to be closed through the first face (41) or the second face (43).
    [0283]
    [0284] The contour of the cover (4) has fastening elements (45) that facilitate the turning of the cover (4) by external turning elements, see FIG. two.
    [0285]
    [0286] FIGS. 10d-10f show an operating sequence in which the reversible nature of the cover (4) can be seen. In FIG. 10d, the cover (4) is closed by the first face (41), so that a first injection of plastic material fills the first volume (V 1 ) to define a first element of the article to be manufactured. FIG. 10e shows the moment in which the cover (4) is turned to close it on the body (2) on its second face (43). During this process it is used to introduce another component of the article to be manufactured, in this case, the outermost part of the sole (P). In FIG. 10f, the cover (4) is closed by the second face (41), so that a second injection of plastic material fills the second volume (V 2 ) to define a second element of the article to be manufactured.
    [0287]
    [0288] As seen in the diagram of FIG. 11, the mold (1) comprises remote identification means (101) configured to transmit information (I) from the mold (1) by radio frequency to a data network (R). In this way, the central data system of the manufacturing plant can receive said information (I) and send the corresponding orders to the mold (1) for its operation.
    [0289]
    [0290] The mold (1) comprises:
    [0291] - local identification means (102) configured to transmit information (I) of the mold (1) by means of wiring and / or direct connection to an electronic device (D); - wireless connection means (103) configured to connect to the Internet and / or to a data network (R); Y
    [0292] - pressure and temperature sensors (104) to know the physical conditions in the inside of it.
    [0293]
    [0294] The mold (1) is electrically powered from its own power source (105) through one or more batteries arranged inside it, and / or from an external power source (E) through an electrical connection socket (106) arranged in it.
    [0295]
    [0296] FIGS. 12a, 12b, 13a and 13b show in greater detail the configuration and operation of the injection mechanism (110) of the mold (1). As can be seen, said injection mechanism (110) is formed by a first injection block (110a) associated with the first lateral piece (2a), and by a second injection block (110b) associated with the second lateral piece ( 2b). Both blocks (110a, 110b) are separable from each other, see FIG 12a, and between them are formed the injection channels (112) that have outlet holes (113), see FIG. 1.
    [0297]
    [0298] In turn, the injection mechanism (110) is configured to slide upwards (dm) through the action exerted by an elastic mechanism (120) arranged between the body (2) and the cover (4). In this case, by the elastic force of a first spring (120a) and a second spring (120b). This causes an upward sliding (dma, dmb) of each of the blocks (110a, 110b) with respect to the lateral pieces (2a, 2b) when the cover (4) is open, see FIGS. 12a and 12b. On the contrary, when the cover (4) is closed, said injection blocks (110a, 110b) slide in the opposite direction to the elastic force of the springs (120a, 120b), thereby producing a pressure of the upper part of the injection mechanism (110) against the cover (4), see FIGS. 13a and 13b. Said pressure guarantees the sealing during the closing of the mold (1), that is, between the body (2) and the cover (4), avoiding leaks of fluid material out of the mold (1).
