    [0002] Dating system for molds
    [0004] The present invention relates to a dating system for molds.
    [0006] Background of the invention
    [0008] In the manufacture of plastic parts by injection, it is common to mark the date of manufacture on the injected part to know at all times the real traceability of the production process and to be able to know the complete history, both of the material used and the guarantee of its origin. .
    [0010] To this end, it is customary for the date to be embossed at the time of injection.
    [0012] For this, there are different models of markers, which are engraved with different numbers arranged on a cylinder that has the numbers engraved on the circular perimeter depending on whether you want to engrave the day, the week, the month, the year, etc.
    [0014] For example, in the month and year model, the numbers from 1 to 12 are engraved on the perimeter, as if it were a clock, and inside this same cylinder, and so that it can rotate on its own axis, it carries another Smaller diameter cylinder that includes an arrow to indicate the number of the day.
    [0016] The particularity of this arrow is that it is engraved in low relief with the necessary depth so that it can be turned by using a screwdriver, to indicate the position of the desired number.
    [0018] As the arrows are deep enough for the screwdriver, the markers are not suitable for thin plastic parts, as well as picking up dirt in the arrow area over time.
    [0020] There are markers with the numbers in high relief, but to be able to manipulate them, the arrow is also in low relief, so they lose their functionality.
    [0021] In addition, in the event that the marker indicates 12 months, it is usual for the same cylinder with a smaller diameter to include the last digits of the corresponding year, in which case at the end of the year the complete cylinder with a smaller diameter must be replaced by one. new that corresponds to the new year.
    [0023] In all cases, the use of a screwdriver is unavoidable to rotate the central axis so that the arrow indicates the corresponding number.
    [0025] The marker cylinders are undoubtedly small in diameter, since they must be inserted into some part of the mold that corresponds to the surface of the figure, any part of the punch of the mold being normally suitable.
    [0027] To change the date of the month or day, the injection of the part must be stopped to turn the indicator arrow using a screwdriver, while to change the year, production must be stopped for as long as necessary to proceed with the change of the corresponding cylinder.
    [0029] If additional information is required in addition to the month and year, it is usual to use more markers, to mark in the same injection process all the information that the product may require.
    [0031] In any case, the momentary stoppage of production is essential, as well as the opening of the mold so that the operator can proceed to turn the arrow, both for a single marker and for several markers.
    [0033] If the mold has one or more cavities, due to the location of the markers it is possible to require a certain specialization and screwdrivers suitable for the size of the rotary shaft slot.
    [0035] In these cases, sometimes due to lack of skill of the operator, poor visibility due to the position of the marker or misuse of the screwdriver, the mold is damaged, or the position of the arrow (s) is incorrectly marked ( s) and the parts are marked with wrong data.
    [0037] Consequently, changing the marker data becomes an uncomfortable task and it is foreseeable that the part will not be controlled as required by the requirements of the product and it is practically impossible for all the parts to reflect the veracity of the data that is used. stipulated as a guarantee of manufacturing control.
    [0039] Another drawback of conventional mold markers is that the information they provide is limited and can be confusing at times.
    [0041] This is because the information varies depending on the orientation of the arrow, and this arrow can be difficult to see.
    [0043] In addition, the information that can be provided is limited, usually month and year, occupying a considerable space in the piece, since all the months of the year are included and the arrow is oriented towards one of them.
    [0045] Description of the invention
    [0047] Therefore, an objective of the present invention is to provide a dating system for molds that allows the information to be read much more clearly on the part.
    [0049] With the dating system for molds of the invention, the aforementioned drawbacks are solved, presenting other advantages that will be described below.
    [0051] The reason for the present invention is to completely change the geometry of the dating systems for molds, and instead of being circular with an arrow that indicates only one of the information in the circle, the dating system of the present invention only includes the date information, for example the month and year, preferably in a linear arrangement, that is, indicating the date with letters and / or numbers forming a line.
    [0053] The dating system according to the present invention is a new traceability element that allows the manufacturing date to be marked with extreme precision, with minimal dimensions and with an unprecedented reading quality in the date marking on parts. plastic, an issue of vital importance for production control.
    [0055] The dating system for molds according to the present invention comprises a marking element that engraves a determined date, wherein said marking element comprises a plurality of interchangeable inserts that indicate the determined date, said determined date being defined by letters and / or numbers.
    [0056] Preferably, said letters and / or numbers are arranged in a line, and said letters and / or numbers indicate, for example, a day number, a month, a week number and / or a year.
    [0058] Advantageously, said interchangeable inserts are removably mounted on a support, and said support preferably comprises a housing provided with a locking element, to lock said inserts in position, and according to a preferred embodiment, said housing extends to the end the bracket furthest from the axis.
    [0060] Preferably, said locking element is located centrally in said housing, leaving two through holes on its sides.
    [0062] Advantageously, said inserts comprise a cavity complementary to said locking element. For example, such a cavity has a trapezium-shaped profile, although it could be any suitable shape.
    [0064] According to a preferred embodiment, the marking element comprises two or more interchangeable inserts.
    [0066] The dating system for molds according to the present invention also preferably comprises a handling tool for placing and removing said interchangeable inserts.
    [0068] According to a preferred embodiment, said manipulation tool comprises a recess for one or more interchangeable inserts and a stop for retaining said interchangeable inserts in said recess.
    [0070] Furthermore, the dating system for molds according to the present invention preferably also comprises an insert storage element, in which inserts that are not currently used in the mold are placed.
    [0072] According to a preferred embodiment, said storage element comprises a storage area with a profile complementary to the cavity of each insert.
    [0074] Advantageously, the locking element, the handling tool and / or the storage element comprise one or more magnets duly polarized to prevent the accidental loss of the interchangeable inserts and fix them in their proper position.
    [0076] Furthermore, said marking element is movable between a position of use and a position of removal and placement of the interchangeable inserts, thanks to axis 4.
    [0078] With the mold dater according to the present invention, the following advantages are achieved, among others:
    [0079] - The reading of the information is much clearer than traditional daters;
    [0080] - It requires a minimum space, which allows it to be adapted to practically any mold; - It is much more dynamic than traditional daters, as they can provide date information in multiple formats, such as day and month, or week and year number, or combinations thereof.
    [0082] In addition, it allows the piece not to present any protrusion, ensuring a completely sharp and functional appearance, which is especially important in pieces whose walls are very thin, for example, in the cosmetic or pharmaceutical industry.
    [0084] Brief description of the drawings
    [0086] For a better understanding of what has been stated, some drawings are attached in which, schematically and only as a non-limiting example, a practical case of embodiment is represented.
    [0088] Figure 1 is a comparison of a date indicated with a conventional dater and a date indicated with the dating system according to the present invention, where the differences in reading can be appreciated;
    [0090] Figure 2 is a perspective view of the handling tool and the storage element of the dating system according to the present invention;
    [0092] Figure 3 is a perspective view of the storage element of the dating system according to the present invention;
    [0094] Figures 4 and 5 show the process of placing two interchangeable inserts with the aid of the manipulation tool of the dating system according to the present invention; Y
    [0095] Figure 6 is a perspective view of the marking element of the dating system according to the present invention.
    [0097] Description of a preferred embodiment
    [0099] As indicated above and as shown in Figure 1, the dating system of the present invention completely changes the geometry of the mold dating systems, and instead of being circular with an arrow pointing only to one of the the information of the circle (on the right in figure 1), the dating system of the present invention only includes the information of the date, for example, the month and year (on the left in figure 1), preferably in a linear arrangement, that is, indicating the date with letters and / or numbers forming a line.
    [0101] For this, the dating system for molds according to the present invention comprises a marking element 1 that engraves a date on a part that is molded in the mold.
    [0103] Said date indicates the date of manufacture of the part that is molded made up of letters and / or numbers, which can include the month and the year, or the day, the month and the year, or the number of the week and the year, or any combination of such information to provide the date.
    [0105] Preferably, said letters and / or numbers are arranged in a line, and only include information on a certain date, unlike conventional date stamps that include all the days of a month or all the months of a year and an arrow indicates the date. that you want to indicate.
    [0107] It should be noted that for the sake of simplicity an embodiment of the marker according to the present invention comprising a single marking element is shown, but the number of marking elements will be adequate to provide the desired information.
    [0108] The marking element 1 comprises two or more interchangeable inserts 2 provided with the desired information, for example, the month and the year. Said information is preferably recorded at its two ends.
    [0110] The marking element 1, at its front end, defines a substantially rectangular profile radiated at its ends to facilitate machining of the mold, with a certain height, as can be seen in figure 5.
    [0111] Said interchangeable inserts 2 are removably mounted on a bracket 3, which is mounted at the end of a shaft 4.
    [0113] For the assembly of the interchangeable inserts 2, said support 3 comprises an inverted U-shaped housing 5 that defines a locking element 6. According to the embodiment shown, said housing 5 extends from one end of the support 3 and the element The lock 6 is positioned in a middle position of the housing 5, so that two through holes are defined on each side of the lock element 6.
    [0115] In order for the inserts 2 to be retained in said housing 5, each insert 2 comprises a cavity 7 with a shape complementary to the shape of the locking element 6. For example, according to the embodiment shown, the cavity 7 has a shaped profile trapeze.
    [0117] Furthermore, said locking element 6 advantageously comprises one or more magnets 14, which retain the interchangeable inserts 2 in position.
    [0119] For removal and placement, the dating system according to the present invention comprises a handling tool 8, which includes a recess 9 for the placement of two or more inserts 2 and a stop 10 to retain the insert (s) 2 in position in said hole 9.
    [0121] This handling tool 8 also comprises one or more magnets to retain the interchangeable inserts 2 in position and prevent accidental loss of the inserts 2.
    [0123] The dating system according to the present invention also comprises a storage element 11 for storing in an organized manner a series of inserts 2 that are not used at the time.
    [0125] This storage element 11 comprises a storage zone 12 where a plurality of inserts 2 placed side by side are placed, and said actuating element 11 also comprises one or more magnets to retain the interchangeable inserts 2 in position and prevent loss. accidental inserts 2.
    [0127] The process of placing two inserts 2 in their position of use in the holder 3 is shown in the figures.
    [0128] In figure 1, the handling tool 8 and the storage element 11 are connected to each other. Once separated, the inserts 2 can be removed from the storage element 11 by means of the handling tool 8.
    [0130] For placement in the holder 3, the inserts 2 can be placed in position in the recess 9 of the handling tool 8, as shown in figure 3.
    [0132] Once placed in their position, the inserts 2 are deposited in said housing 5, as shown in figure 4, with the help of the manipulation tool 8.
    [0134] When the inserts 2 have been placed in the holder 3, the handling tool 8 is removed and the inserts 2 are left in their position of use, as shown in figure 5.
    [0136] For the removal of the inserts 2, a reverse process is carried out to the placement process described above.
    [0138] For the dating of a part, the marking element 1 is moved to the appropriate position in the mold (not shown in the figures), specifically in a position that protrudes slightly from the punch of the mold. To do this, the inserts 2 of the marking element 1 comprise chamfers 13, corresponding to the protruding position of the marking element 1. One of the chamfers is indicated in Figure 3, which acts as a ramp to overcome a possible misalignment during assembly. .
    [0140] The axis 4 allows the marking element 1 to be placed in a position for use or in a position for inserting and removing the inserts. This movement through the axis 4 can be actuated in any suitable way, for example by means of a pneumatic piston.
    [0142] In the position of inserting and removing the inserts, the marking element 1 comes out of its housing in the mold, for example, half its height, and once the inserts have been changed, the marking element 1 returns to its position of use.
    [0144] Although reference has been made to a specific embodiment of the invention, it is clear to a person skilled in the art that the described mold dating system is susceptible to numerous variations and modifications, and that all the mentioned details can be replaced by others technically equivalent, without departing from the scope of protection defined by the appended claims.
