Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a wire groove structure for an automotive injection mold. Background Art

[0002] Existing automotive injection molds generally have connecting wires for connecting test equipment or functional equipment. The connecting wires generally include wires and plugs, and the wires and plugs need to be fixed on the injection mold.

[0003] See the appendix Figure 1 The appendix Figure 1 is a wire groove structure in an existing automotive injection mold. It includes a template 11, and a groove 12 is formed on the outer surface of the template 11. One side of the groove 12 is detachably and fixedly installed with a wire pressing plate 13. During actual assembly, it is necessary to first remove the wire pressing plate 13, then place the connecting wire into the groove 12, and then reinstall the wire pressing plate 13. The wire pressing plate 13 is used to press the connecting wire and prevent the connecting wire from slipping out of the groove 12. However, the wire pressing plate 13 may cause wear to the insulation layer outside the connecting wire. Since most of this wire groove structure is exposed on the surface of the template 1, after long-term use, it is very easy for oil dirt or dust to accumulate in the groove 12, and it is difficult to clean. Moreover, this wire groove structure is troublesome to process. It is necessary to add a wire pressing plate 13 to prevent the connecting wire from shifting. Therefore, it is necessary to set up threaded holes and other structures on the template 11 to fix the wire pressing plate 13, which has problems of complex structure, high manufacturing cost, and difficult processing. Moreover, if the wire pressing plate 13 is too small, the part of the connecting wire far from the wire pressing plate 13 may warp, and it is also necessary to add multiple wire pressing plates 13 to solve this problem, making this wire groove structure very inconvenient to use. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a wire groove structure for an automotive injection mold, which can solve the problems of complex structure, exposed connecting wires, and easy dust accumulation in the past by changing the opening method and position of the wire groove.

[0005] To solve the above technical problem, the utility model discloses a wire groove structure for an automotive injection mold, including a mold body. An installation groove for installing a plug is formed on the side surface of the mold body; a first wire routing hole is formed inside the mold body, one end of the first wire routing hole communicates with the installation groove, and the other end of the first wire routing hole communicates with the outer surface of the mold body.

[0006] Furthermore, a second wire routing hole is formed inside the mold body. One end of the second wire routing hole communicates with the hole wall of the first wire routing hole, and the other end of the second wire routing hole communicates with the outer surface of the mold body.

[0007] Further, the extending direction of the first wire hole is perpendicular to that of the second wire hole.

[0008] Further, the first wire hole extends in the vertical direction, with its top end communicating with the installation groove and its bottom end communicating with the bottom surface of the mold body; the second wire hole extends in the horizontal direction.

[0009] Further, the cross-sectional shape of the first wire hole is circular.

[0010] Further, the cross-sectional shape of the second wire hole is circular.

[0011] Further, the installation groove includes a round hole portion and a long strip portion communicating with the round hole portion. The round hole portion is used for inserting a plug, and one end of the first wire hole communicates with the long strip portion.

[0012] Further, the first wire hole and the second wire hole are arranged in a T shape.

[0013] Further, the aperture of the first wire hole is larger than that of the second wire hole, and the aperture of the first wire hole is not less than twice the outer diameter of the inner wire.

[0014] Further, the aperture of the first wire hole is equal to that of the second wire hole.

[0015] The utility model has the following beneficial effects: By providing the first wire hole inside the mold body, the wire can reach the installation groove through the first wire hole and be electrically connected to the plug, reducing the area where the connecting wire is exposed outside the mold body, effectively protecting the wire. Since the first wire hole is located inside the mold body, the accumulation of oil dirt or dust can be minimized. Moreover, the overall structure of the wire groove structure of this application is simple and compact, convenient for processing, avoiding the use of accessories, reducing processing man-hours and production costs, making the appearance of the mold cleaner and more beautiful, and solving the problem of the complex wire groove structure in the past.

[0021] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0022] The terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, mechanism, product or terminal including a series of steps or units is not limited to the listed steps or units, but may optionally further include steps or units not listed, or may optionally further include other steps or units inherent to these processes, methods, products or terminals.

[0023] Referring to "embodiment" herein means that a specific feature, structure or characteristic described in connection with the embodiment may be included in at least one embodiment of the present invention. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0024] The present invention discloses a detailed implementation manner of a wire groove structure for an automotive injection mold. Please refer to Figures 2 to 4 , which includes a mold body 2, and an installation groove 21 for installing a plug is opened on the side of the mold body 2. Optionally, the installation groove 21 includes a round hole part 22 and a long strip part 23 communicated with the round hole part 22. The round hole part 22 is used for inserting or fixing the plug. The long strip part 23 has an opening on the side of the mold body 2. Its main function is to leave a certain wiring space to facilitate the subsequent wiring work between the wire and the plug. In addition, the long strip part 23 can also store a certain length of wire to prevent the wire from separating from the plug due to dragging, playing a certain buffering role and making it more convenient to observe the connection situation between the wire and the plug.

[0025] As a further improvement, a first wire routing hole 31 is provided on the bottom surface of the mold body 2 and arranged vertically inside the mold body 2. The top end of the first wire routing hole 31 communicates with the long strip portion 23 of the installation groove 21, and the bottom end of the first wire routing hole 31 communicates with the bottom surface of the mold body 2. A second wire routing hole 32 is also provided on the side surface of the mold body 2 and arranged horizontally inside the mold body 2. One end of the second wire routing hole 32 communicates with the hole wall of the first wire routing hole 31, and the other end communicates with the side surface of the mold body 2.

[0026] In this embodiment, the cross-sectional shape of the first wire routing hole 31 is circular, and the cross-sectional shape of the second wire routing hole 32 is also circular. It can be understood that both the first wire routing hole 31 and the second wire routing hole 32 can be directly obtained by drilling. The processing is convenient and fast, and the wire can be limited without setting other fixing accessories, reducing the processing cost and difficulty.

[0027] In addition, since the first wire routing hole 31 is opened vertically and the second wire routing hole 32 is opened horizontally, the first wire routing hole 31 and the second wire routing hole 32 are arranged in a T shape, so that the wire can be inserted from the bottom surface or the side surface of the mold body 2, which can be applicable to various different working conditions and improve the applicability of wiring. In addition, the aperture of the first wire routing hole 31 and the aperture of the second wire routing hole 32 can be set according to the actual situation, and they can be made equal or unequal. For example, when the plug needs to connect two wires, the aperture of the first wire routing hole 31 can be set to be larger than the aperture of the second wire routing hole 32. The aperture of the second wire routing hole 32 is equal to or slightly larger than the outer diameter of the wire, and the aperture of the first wire routing hole 31 is equal to or slightly larger than twice the outer diameter of the wire. In this way, one wire can be inserted from the second wire routing hole 32 on the side surface of the mold body 2, and the other wire can be inserted from the first wire routing hole 31 on the bottom surface of the mold body 2. Both wires reach the installation groove 21 after passing through the first wire routing hole 31, thus completing the wiring work, which can minimize the entry of oil dirt or dust into the wire routing hole.

[0028] Compared with the prior art, the wire groove structure of this embodiment enables the wire to reach the installation groove 21 through these wire routing holes and be electrically connected to the plug by providing the first wire routing hole 31 and the second wire routing hole 32 inside the mold body 2, reducing the area where the wire is exposed outside the mold body 2, effectively protecting the wire, and improving the use safety of the wire. Since the wire routing holes are inside the mold body 2, they are not easy to hide oil dirt or dust and are also safer. In addition, the overall structure of the wire groove structure of this embodiment is simple and compact, the processing is convenient, the use of accessories is avoided, the processing time and production cost are reduced, and the appearance of the mold is cleaner and more beautiful, solving the problem of the complex wire groove structure in the past.

[0029] Finally, it should be noted that: What is disclosed by a wire groove structure for an automotive injection mold disclosed in the embodiments of the present utility model is only the preferred embodiments of the present utility model, and is only used to illustrate the technical solutions of the present utility model, rather than limiting it; Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
