    description
    INJECTION MOLDING MACHINE WITH INDEX PLATE DRIVE
    The invention relates to an injection molding machine for a multi-component injection molding by means of the so-called Indexplattenverfahrens.
    For the production of multi-component injection molded parts, various process techniques and corresponding injection molding machines from the prior art are known. By way of example, the turntable technology, the indexable plate technique or the so-called index plate method may be mentioned.
    When Indexplattenverfahren the injection mold is modified in such a way that an additional third plate is disposed between two basic tool halves, the so-called index plate. This is rotatable about a central axis and can be moved axially in the machine longitudinal direction. The index plate forms a central part of the cavity, in which a preform arises, which can remain unchanged. After lifting off the fixed tool part, the index plate rotates at a fixed angle, for example 120 ° or 180 °, and the pre-molded part is converted into another cavity, in which another component can be molded. Due to the axial stroke, which is subjected to the index plate before turning, it is possible to implement the pre-shaped parts, unlike arranged on turntables tool halves, in a cavity whose contour also changes on the moving platen facing side, so that, for example Injections are possible. After turning, the index plate is axially retracted back into the corresponding cavities. When indexing plates process, it is known to perform the rotary drive for the index plate as part of the tool and provide a machine-side drive for the linear drive. For example, the rotary shaft of the index plate can be brought into operative connection with the ejector mechanism of the injection molding machine. For this prior art reference is made to the article by Hansjörg Keusgen "Pneumatic forced removal" in the journal "Plastics, born 90 (2000) 4, pages 72-74.
    From DE 10145461 AI an injection molding machine for the index plate method is known in which an intermediate plate is provided between the movable platen and the mold half mounted on this. In this intermediate plate, a hollow shaft motor is housed, which serves as a rotary drive for the rotary shaft connected to the index plate. In an alternative embodiment, the rotary drive with a hollow shaft can also be arranged in a recess of the movable platen, wherein this recess is located on the side facing the mold of the movable platen.
    In addition, injection molding machines have become known in which both the linear drive and the rotary drive of the index plate no longer exist on the tool side, but the machine side. In this regard, DE102004040109A1 a first variant is known in which outside of the installation space for an injection mold behind the movable platen a support plate is provided, which is connected via columns with the movable platen. The ejector plate of the ejector system of the injection molding machine is supported on the columns and can be moved in the machine longitudinal direction. With the index plate, a rotary shaft is connected, which is rotatably mounted but axially fixed in the ejector. By moving the ejector plate in the machine longitudinal direction, as is normally provided for the ejection of finished moldings, the rotary shaft and thus the index plate can be moved axially. On the side facing away from the ejector plate of the support plate, a rotary drive is provided, which is in operative connection with the rotary shaft connected to the index plate. Since the carrier plate is stationary and the rotary shaft is moved in the machine longitudinal direction, the torque is transmitted via a hollow shaft and designed as a VIelkellwelle portion of the rotary shaft. In a further variant of DE102004040109A1, the rotary drive can also be arranged on the ejector plate, so that no splined shaft is required for the torque transmission, but the rotary shaft can be connected directly to the motor. DE102005005202A1 discloses an arrangement of the rotary drive on or in the ejector plate. With these known injection molding machines, it is possible to be able to displace an indexing plate of an injection molding tool both in the machine longitudinal direction by means of machines, as well as to effect a rotation of the index plate in the extended state, in particular to convert injection molded parts from one cavity into another cavity. For ejecting the finished mold parts disposed in the tool ejector pins are used, which can be operated, for example, hydraulically or pneumatically.
    A disadvantage of this prior art is initially a high design and manufacturing effort in each tooling to provide the ejection function. Furthermore, the most commonly used additional tool-integrated ejection hydraulics cause increased maintenance and care of each tool, which, with increased cleanliness requirements, e.g. can skyrocket during production under clean room conditions.
    Based on this prior art, the present invention seeks to minimize the complexity of index plate tools and function combinations which are recurrently required in a large part of these relocate in the machine. In particular, the combination of the independently operable rotary and translatory movements Indexausubbewegung, rotary motion and ejector.
    The solution of this object is achieved by an injection molding machine with the features of claim 1. Advantageous embodiments and further developments can be found in the dependent claims.
    According to the invention, two additional plates are arranged behind one of the platen outside of the installation space of the injection mold, in particular behind the movable platen, namely a movable machine longitudinal direction in the machine ejector plate and additionally movable in the machine longitudinal direction machine side additional plate. The ejector plate is formed in a known manner for receiving Auswerferstangen or provided with ejector rods. With built-in ejector rods finished moldings can be ejected from the injection mold by moving the ejector plate in the machine longitudinal direction in a known manner. The additional plate is provided for actuating the index plate. On the additional plate, a rotary drive is provided, wherein the rotary drive is in operative connection with a rotary shaft, which is connectable or connected to a rotatable part of the injection mold, in particular with an index plate. The rotary shaft connected or connectable to the index plate may be axially fixed and rotatably supported in or on the auxiliary plate and operatively connected to an output shaft of the rotary actuator. By means of the rotary drive, the index plate can be rotated in the extended state to a desired position. In order to be able to move the index plate also in the machine longitudinal direction, the additional plate itself can also be moved in the machine longitudinal direction. The ejector plate and the additional plate are thus independently movable in the machine longitudinal direction. It is only necessary to take into account which traverse path from the ejector plate and which traverse path from the additional plate are to be traversed at which time. In this respect, the distance to be provided for the travel path of the ejector plate and the distance to be provided for the travel path of the additional plate in the design of the injection molding machine according to the invention must be taken into account. Furthermore, make sure that the ejector plate and the additional plate are moved back and forth in the correct order. In any case, the ejector can be used in a known manner for ejecting moldings from the injection mold and it is not necessary in the injection mold itself to provide an ejector. This can be dispensed with, for example, core pullers and hydraulics in the injection mold itself, which also has a positive effect on the cost of the injection mold.
    Preferably, there is a first linear drive, which is in operative connection with the ejector plate in operative connection or can be brought into operative connection, and a second linear drive, which is operatively connected to the auxiliary plate in operative connection or can be brought into operative connection. The first linear drive is to be referred to below as the ejector linear drive. The second linear drive is to be referred to below as index plate linear drive. The ejector linear drive and the Indexplat-th linear drive are independent of each other, in particular, the two linear actuators can be operated independently. The device and the operation of the two linear drives can be done via the control of the injection molding machine.
    The invention also allows the use of less complex in the technical sense index plate tools with the same functionality. This leads to reduced costs for the operator in designing, manufacturing and operating such injection molding tools.
    The relative arrangement of ejector and additional plate to each other and with respect to the platen on the other hand depends on the particular circumstances.
    According to a preferred embodiment of the invention, the ejector plate can be arranged behind the additional plate, namely in such a way that the additional plate is located between the ejector plate and the platen. In this case, the ejector plate can preferably have a recess which is arranged and dimensioned in the ejector plate such that the rotary drive of the additional plate can at least partially pass through this recess in the ejector plate. This makes it possible to keep the distance between the ejector and the additional plate as small as possible. As a result, the space occupied by the injection molding machine does not become excessively large. In particular, it may be the same or only slightly larger than in an injection molding machine which has only one ejector device on the machine side with ejector plate. Such an embodiment is particularly advantageous when the rotary drive is arranged on the machine longitudinal axis and the longitudinal axis of the rotary drive or the axis of rotation coincides with the machine longitudinal axis.
    According to a further embodiment it can be provided that in an arrangement of the ejector behind the additional plate one or more recesses in the additional plate are present, which beab-spaced from the machine longitudinal axis and from the rotary shaft are arranged in the additional plate, said recesses arranged and dimensioned in such a way in the additional plate that ejector rods connected to the ejector plate can be guided through these recesses located in the additional plate.
    According to an alternative embodiment can also be provided to arrange the ejector behind the additional plate, so that the additional plate between the Auswer-iferplatte and the platen is. In this case, the additional plate should have one or more recesses which are spaced from the machine longitudinal axis and the rotary shaft in the additional plate, said recesses are arranged and dimensioned in such a way in the additional plate that connected to the ejector ejector rods through this in the Additional plate located recesses are guided.
    Advantageously, a support plate may be provided, which is arranged behind the platen, behind which the ejector and the additional plate are arranged, wherein the arrangement of the support plate is such that the ejector and the additional plate between the support plate and this platen are located. Columns may be provided between the support plate and the platen, and the ejector plate and the auxiliary plate may have recesses tuned to the columns through which the columns pass. The ejector plate and the additional plate can be supported in this way on the columns and in the process in the machine longitudinal direction, the ejector and the additional plate are guided on the columns.
    The support plate is particularly suitable for the fact that there are provided a first linear actuator as ejector linear drive for moving the ejector plate and a second linear actuator as index plate Llnearantrieb to process the additional plate. In accordance with the invention, the ejector linear drive and the index plate linear drive can be operated independently of each other, so that the ejector plate and the additional plate can be moved independently of one another on the columns in the machine longitudinal direction. Preferably, the ejector linear drive and / or the index plate linear drive can be designed as hydraulic drives. Instead of a hydraulic drive, other drives may be provided as ejector linear drive and as index plate linear drive. The linear drives are preferably arranged on the back of the carrier plate. In the case of hydraulic drives, the hydraulic cylinders are thus mounted on the back of the support plate and the piston rods, which are in operative connection with the ejector and the additional plate are passed through matching recesses in the support plate.
    As a rotary drive known drives can be used, preferably electrical drives are provided as a rotary drive. It may be a motor with a gear or a direct drive, which may be in particular a torque motor. Such a rotary drive may preferably be provided on a side facing away from the movable mold-platen side of the additional plate in order not to restrict the axial relative movement of additional plate and platen too much. The rotary drive can be arranged on the machine longitudinal axis, so that both the longitudinal axis of the rotary drive and the longitudinal axis of the rotary shaft lie on the machine longitudinal axis. But the rotary drive can also, if it is not designed as a direct drive, are arranged elsewhere in the additional plate and also in a different orientation of its longitudinal axis. For example, an arrangement could be provided as known from DE 10 2004 040 109 AI, i. the rotary drive is mounted on the additional plate so that its longitudinal axis is orthogonal to the machine longitudinal axis.
    In order to be able to supply media, in particular fluid media, to the rotatable part of the injection molding tool, in particular the index plate, a rotary feedthrough or a hose leadthrough can be provided. When using a rotary feedthrough, the non-rotatable part of the rotary feedthrough can be firmly flanged to the additional plate. The rotatable part of the rotary feedthrough is at least a part of the rotary shaft. A rotary feedthrough has the advantage that the rotary shaft can be rotated in the sense that the rotary shaft can be completely rotated by 360 ° C and on. In the case of a hose feedthrough, the hoses for the media supply are connected directly to the rotary shaft, more precisely to the channels running in the rotary shaft for supplying media. The rotary shaft can therefore only be turned back and forth to a limited extent. A spinning or clocking through the rotary shaft is not possible with a hose feedthrough. This disadvantage is offset by the lower costs compared to a rotary feedthrough.
    The rotary shaft is preferably axially fixed and rotatably mounted in or on the additional plate. Optionally, an additional storage for a passing through the platen section of the rotary shaft may be provided in or on the platen. Such an embodiment is particularly suitable when the tool-side storage is eliminated and low rotational weights are to be realized with small excavation paths of the index unit.
    The rotary shaft may consist of a plurality of interconnected or connectable parts, comprising at least a first part, which is in operative connection with the rotary drive, and at least a second part which rotatably connected to the rotatable part of the injection mold, in particular with the index plate connected or connectable. The specific design of the rotary shaft depends on the particular circumstances and requirements, in particular on the nature and extent of the media supply. It also depends on what requirements in terms of dynamics and precision of the movement in the machine longitudinal direction and the rotational movement of the index plate who made the. The rotary shaft can thus be designed in several parts, in particular also in two parts, wherein the parts are releasably connected to one another in such a way that the torque can be transmitted from the rotary drive to the additional plate via the rotary shaft to the index plate. The rotary shaft can be designed in several parts in a manner as described in DE 102004040109A1 or DE102005005202A1.
    The invention will be explained in more detail with reference to an embodiment and with reference to Figures 1 to 3.
    On a platen 1 of a known per se and therefore not described in detail injection molding a tool half 2 of an injection mold for a multi-component or Mehrfarbenspritzgießverfahren with index plate operation with the interposition of a centering ring 3 is attached. Multi-component injection molding can be understood as meaning the layered construction of an injection molded part with the same plastic in addition to the "classical" multicomponent injection molding. Standard mold mounting plates can be used with a hole pattern according to EUROMAP The tool half 2 consists essentially of a base plate 4, support strips 5 and In addition, ejector pins 9 are provided, which are in operative connection with the ejector plate 40, for example via suitable ejector rods 41. However, it is also possible to execute the ejector rods 41 so long that they engage in The pins 10 only dip into suitable bores in the index plate 8 and are not needed in the present case. In the base plate 1 and in the base plate 4 and in the mold plate 6 sliding bushes 11 are also provided which, depending on the application, can be used individually or in K combination can be provided. Behind the platen 1 and spaced therefrom in a suitable manner, a support plate 15 is provided. The support plate 15 is connected by means of columns 14 fixed to the movable platen 1. On the columns 14, an ejector plate 40 and an additional plate 12 are supported and guided in the machine longitudinal direction. On the additional plate 12 guide bushes 13 are provided for this purpose. Such guide bushings may also be provided on the ejector plate 40. The ejector plate 40 and the additional plate 12 are thus movable on the columns 14 between the support plate 15 and the platen 1 in the machine longitudinal direction.
    By means of two located in a plane to the left and right of the central axis of the first hydraulic cylinder 17b and 18b (see Fig. 3), the additional plate 12 can be moved away to the platen 1 and from this. By means of two further hydraulic cylinders 17a and 18a, the ejector plate 40 can be moved toward the platen 1 and away from it. The hydraulic cylinders 17a and 18a form a first linear drive as ejector linear drive for moving the ejector plate in the machine longitudinal direction. The hydraulic cylinders 17b and 18b form a second linear drive as Indexplatten linear drive for moving the additional plate in the machine longitudinal direction. The ejector linear drive and the index plate linear drive according to the invention are independently operable.
    The index plate 8 is connected to a rotary shaft which extends through the tool half 2 and the platen 1 through to the additional plate 12. On the additional plate 12, a rotary drive 20 is provided, which is in operative connection with the rotary shaft. As a rotary drive in the present case, an electric geared motor is provided. The torque generated by the engine is transmitted via a planetary gear to a drive part 21 of the rotary shaft. The motor is arranged on the back of the additional plate 12 and the drive part 21 of the rotary shaft is passed through the additional plate 12 and rotatably connected to the planetary gear.
    The engine together with its transmission is arranged in this example on the machine longitudinal axis, so that both the longitudinal axis of the rotary drive and the longitudinal axis of the rotary shaft lie on the machine longitudinal axis. But the rotary drive can also, if it is not designed as a direct drive, are arranged elsewhere in the additional plate. This drive part 21 extends through the additional plate 12 to the motor 20 therethrough.
    Right of the additional plate 12, the drive part 21 and the supply part 22 via a releasable coupling 16 are interconnected. The drive member 21 is axially fixed in the additional plate 12, but rotatably mounted. At its end facing away from the index plate 8, the supply part 22 has a rotary feedthrough 23 with a plurality of circumferential annular grooves 26, into the channels for the media supply of the index plate. In the present example, two channels 24 and 25 are shown, for example, for a cooling liquid or generally for a tempering medium. It can be water or oil. Furthermore, compressed air can also be conducted via channels in the supply part 22 to the index plate 8. The channels are thus provided in particular for the transmission of fluid media. If necessary, electric cables can also be led to the index plate 8 and, for example, led out of the channel 38 via a lateral outlet 40. The non-rotatable outer part of the rotary feedthrough 23 is secured in the present example by means of retaining rings 29 on the supply member 22 and secured against rotation with respect to the additional plate 12, for example by means of one or more attached to the auxiliary plate 12 traverse 36. Sealing rings 27 and 28 provide a tight connection between the rotatably outer part of the rotary union and the rotatable inner part of the rotary feedthrough, which is part of the supply part 22 of the rotary shaft. The supply part 22 and the drive part 21 together form the rotary shaft 19, via which the torque generated by the motor 20 can be transmitted to the index plate 8.
    In the ejector 40, a first recess AM is provided, which is arranged and dimensioned in the ejector plate 40 such that the rotary drive 20 of the additional plate 12 can at least partially pass through this recess AM in the ejector. The additional plate 12 has a plurality of recesses ZI, Z2,..., Which are arranged at a distance from the machine longitudinal axis and from the rotary shaft 19 in the additional plate 12, wherein these recesses ZI, Z2, .derart are arranged and dimensioned in the additional plate 12, that ejector rods 41 connected to the ejector plate 40 can be passed through these recesses ZI, Z2, ... located in the additional plate 12.
    During operation of the injection molding machine, the following procedure may result. First, the injection mold 2 is closed and in a first cavity, a pre-molded part is produced. In this case, the ejector plate 40 and the additional plate 12 are in a rear end position. Subsequently, the injection mold is raised and the pre-molded part can be converted into a second cavity in which the finished molded part is produced. For this purpose, the auxiliary plate linear drive is actuated and the additional plate 12 moved out together with the rotary shaft 19 and the index plate 8 from the mold half 2 (situation according to Figure 2). Subsequently, the rotary drive 20 is switched active and the rotary shaft 19 is rotated by 180 °. Thereby, the index plate 8 is rotated by 180 ° and the pre-molded part is positioned in the region of the second cavity. Now the additional plate 12 can be moved back to its rear end position. As a result, the rotary shaft 19 is retracted together with the index plate 8 and positioned the pre-molded part in the second cavity. If the ejector plate 40 and the additional plate 12 are in the rear end position (pointed position), the tool can be closed and subsequently a second plastic component can be injection-molded onto the pre-molded part in the second cavity. At the same time, a new pre-molded part can be produced in the first cavity. Subsequently, the injection mold is raised. By means of a feed of the ejector plate 40 by activation of the ejector linear drive 17a, 18a, the finished part can be ejected from the second cavity. Subsequently, the ejector plate 40 is moved back into the spray position. By means of a feed of the additional plate 12 by activation of the additional plate linear drive 17b, 18b, the index plate 8 can be moved out again and rotated by activating the rotary drive 20 again by 180 °. As a result, a pre-molded part is again positioned above the second position released by the ejection.
    Now, the additional plate 12 can be moved back to the rear end position. As a result, the rotary shaft 19 is retracted together with the index plate 8 and positioned the pre-molded part in the second cavity. Are ejector 40 and additional plate 12 in the rear end position (spray position), the tool can be closed. The injection cycle begins again.
