Abstract
Description
Technical Field
[0001] This disclosure relates to the field of injection molding, and in particular to an injection mold and injection molding equipment for communication structural components. Background Technology
[0002] In the field of communication equipment, in order to combine structural strength and anti-interference performance, plastic and metal components are often combined into a whole. This is achieved by pre-placing the metal in a mold through insert injection molding, and then using injection molding to wrap the molten plastic around the metal to achieve integrated molding.
[0003] like Figure 1 The communication structure shown consists of two metal parts, a first metal part and a second metal part, which are stacked one on top of the other. The two ends of the first metal part and the two ends of the second metal part are fixed together by injection molding plastic parts. However, during the injection molding process, due to factors such as the impact of the molten plastic, cooling shrinkage force, and mold closing pressure, the metal parts are prone to deformation, displacement, or poor bonding. This means the injection mold's fixing effect on the metal parts is poor, leading to low precision or defective products.
[0004] Therefore, there is an urgent need for an injection mold that can effectively fix metal parts and prevent them from deforming or shifting. Utility Model Content
[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an injection mold and injection equipment for communication structural components that have a better metal part fixing effect and can avoid deformation and displacement of the metal parts.
[0006] The purpose of this disclosure is achieved through the following technical solution:
[0007] An injection mold for communication structural components, comprising:
[0008] An upper mold and a lower mold are provided, the upper mold and the lower mold being arranged opposite to each other. The upper mold contains an upper mold core, and the lower mold contains a lower mold core. When the upper mold core and the lower mold core move towards each other, the molds close together.
[0009] The injection mold further includes a first insert, a second insert, and a movable plate assembly. The first insert is installed in the upper mold core, and the second insert is installed in the lower mold core. The first insert and the second insert together form a receiving groove for receiving the first metal part and the second metal part. The upper mold core, the lower mold core, the first insert, and the second insert together form an injection cavity for injection molding a plastic part.
[0010] The movable plate assembly includes a movable plate, a first limiting post, and a second limiting post. The movable plate is movably connected to the lower mold. The first limiting post and the second limiting post are both installed on the movable plate. The lower mold core has a first clearance hole and a second clearance hole. The second insert has a third clearance hole and a fourth clearance hole. The first clearance hole and the third clearance hole are correspondingly arranged, and the second clearance hole and the fourth clearance hole are correspondingly arranged. The first limiting post is used to move and pass through the first clearance hole and the third clearance hole in sequence, so that the end of the first limiting post is located in the limiting hole of the first metal part. The second limiting post is used to move and pass through the second clearance hole and the fourth clearance hole, so that the end of the second limiting post is located in the limiting hole of the second metal part.
[0011] In one embodiment, the injection cavity is located at the end of the first insert or the second insert.
[0012] In one embodiment, the first limiting post is cylindrical.
[0013] In one embodiment, the second limiting post is rectangular.
[0014] In one embodiment, the number of the first limiting posts is multiple, and the multiple first limiting posts are spaced apart along the length of the moving plate; and / or
[0015] The number of the second limiting posts is multiple, and the multiple second limiting posts are arranged at intervals along the length of the moving plate.
[0016] In one embodiment, the first limiting post is located in the middle of the movable plate, and the second limiting post is located at the periphery of the movable plate.
[0017] In one embodiment, the movable plate assembly further includes an ejector post mounted on the movable plate. The lower mold core has a first through hole, and the second insert has a second through hole. The first through hole and the second through hole are correspondingly arranged. The ejector post is used to move and pass through the first through hole and the second through hole in sequence, so that the ejector post abuts against the second metal part and ejects the second metal part out of the receiving groove.
[0018] In one embodiment, the first insert is screwed to the upper mold core by screws, and the second insert is screwed to the lower mold core by screws.
[0019] In one embodiment, the movable plate is provided with a guide post, the lower mold is provided with a guide hole, the guide post is fitted with an elastic element, and the elastic element is connected to the lower mold so that the guide post is telescopically disposed within the guide hole.
[0020] An injection molding apparatus comprising an injection mold for communication structural components as described in any of the above embodiments.
[0021] Compared with the prior art, this disclosure has at least the following advantages:
[0022] In the aforementioned injection mold for communication structural components, a first insert is disposed in the upper mold core, and a second insert is disposed in the lower mold core. The first and second inserts together form a receiving groove. Before injection molding, the first and second metal parts are stacked and placed in the receiving groove. When the moving plate moves under the drive of the cylinder, it drives the first and second limiting posts to move together, so that the first limiting post passes through the first and third clearance holes in sequence, and the second limiting post passes through the second and fourth clearance holes in sequence. This results in the end of the first limiting post being located in the limiting hole of the first metal part, and the end of the second limiting post being located in the limiting hole of the second metal part. When molten injection liquid is injected into the injection cavity, the first limiting post fixes the first metal part, and the second limiting post fixes the second metal part. This provides a better fixing effect for the first and second metal parts, so as to avoid displacement or deformation of the first and second metal parts during the injection molding process.

However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.
[0030] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0032] This disclosure provides an injection mold for communication structural components, including an upper mold, a lower mold, a first insert, a second insert, and a movable plate assembly. The upper mold and the lower mold are disposed opposite to each other. The upper mold has an upper mold core, and the lower mold has a lower mold core. When the upper mold core and the lower mold core move towards each other, the mold closes. The first insert is installed in the upper mold core, and the second insert is installed in the lower mold core. The first insert and the second insert together form a receiving groove for receiving a first metal part and a second metal part. The upper mold core, the lower mold core, the first insert, and the second insert together form an injection cavity for injection molding a plastic part. The movable plate assembly includes a movable plate and a first limiting... The moving plate is movably connected to the lower mold. The first and second limiting posts are both installed on the moving plate. The lower mold core has a first and a second clearance hole. The second insert has a third and a fourth clearance hole. The first and third clearance holes are correspondingly arranged, and the second and fourth clearance holes are correspondingly arranged. The first limiting post is used to move and pass through the first and third clearance holes in sequence, so that the end of the first limiting post is located in the limiting hole of the first metal part. The second limiting post is used to move and pass through the second and fourth clearance holes, so that the end of the second limiting post is located in the limiting hole of the second metal part.
[0033] In the aforementioned injection mold for communication structural components, a first insert is disposed in the upper mold core, and a second insert is disposed in the lower mold core. The first and second inserts together form a receiving groove. Before injection molding, the first and second metal parts are stacked and placed in the receiving groove. When the moving plate moves under the drive of the cylinder, it drives the first and second limiting posts to move together, so that the first limiting post passes through the first and third clearance holes in sequence, and the second limiting post passes through the second and fourth clearance holes in sequence. This results in the end of the first limiting post being located in the limiting hole of the first metal part, and the end of the second limiting post being located in the limiting hole of the second metal part. When molten injection liquid is injected into the injection cavity, the first limiting post fixes the first metal part, and the second limiting post fixes the second metal part. This provides a better fixing effect for the first and second metal parts, so as to avoid displacement or deformation of the first and second metal parts during the injection molding process.
[0034] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:
[0035] like Figures 2 to 5 As shown, an injection mold 10 for a communication structural component according to one embodiment includes an upper mold 100, a lower mold 200, a first insert 300, a second insert 400, and a movable plate assembly 500. The upper mold 100 and the lower mold 200 are disposed opposite to each other. The upper mold 100 has an upper mold core 110, and the lower mold 200 has a lower mold core 210. When the upper mold core 110 and the lower mold core 210 move toward each other, the mold closes. The first insert 300 is mounted on the upper mold core 100. Inside the mold core 110, the second insert 400 is installed inside the lower mold core 210. The first insert 300 and the second insert 400 together form a receiving groove (not shown in the figure). The receiving groove is used to receive the first metal part 10a and the second metal part 10b. The upper mold core 110, the lower mold core 210, the first insert 300 and the second insert 400 together form an injection cavity (not shown in the figure). The injection cavity is used for injection molding plastic parts.
[0036] Further, the movable plate assembly 500 includes a movable plate 510, a first limiting post 520, and a second limiting post 530. The movable plate 510 is movably connected to the lower mold 200. The first limiting post 520 and the second limiting post 530 are both installed on the movable plate 510. The lower mold core 210 has a first clearance hole and a second clearance hole. The second insert 400 has a third clearance hole and a fourth clearance hole. The first clearance hole and the third clearance hole are correspondingly arranged, and the second clearance hole and the fourth clearance hole are correspondingly arranged. The first limiting post 520 is used to move and pass through the first clearance hole and the third clearance hole in sequence, so that the end of the first limiting post 520 is located in the limiting hole of the first metal part 10a. The second limiting post 530 is used to move and pass through the second clearance hole and the fourth clearance hole, so that the end of the second limiting post 530 is located in the limiting hole of the second metal part 10b.
[0037] In this embodiment, the upper mold core 110 is embedded in the upper mold 100, the lower mold core 210 is embedded in the lower mold 200, the first insert 300 is embedded in the upper mold core 110, and the second insert 400 is embedded in the lower mold core 210. Both the first insert 300 and the second insert 400 are provided with grooves. Before injection molding, the first metal part 10a and the second metal part 10b are stacked and placed in the groove of the first metal part 10a so that when the first insert 300 and the second insert 400 abut, a receiving groove is formed, that is, the first metal part 10a and the second metal part 10b are located in the receiving groove. The moving plate 510 is connected to the cylinder, and the cylinder drives the moving plate 510 to move upward, so as to move the first limiting post 520 and the second limiting post 530 upward together. The first limiting post 520 passes through the first and third clearance holes in sequence, and the second limiting post 530 passes through the second and fourth clearance holes in sequence, so that the end of the first limiting post 520 is located in the limiting hole of the first metal part 10a, and the end of the second limiting post 530 is located in the limiting hole of the second metal part 10b. In this way, during the injection of molten injection liquid into the injection cavity, the first metal part 10a is fixed by the first limiting post 520, and the second metal part 10b is fixed by the second limiting post 530. That is, the fixation of the first metal part 10a and the second metal part 10b is better, so as to avoid the deformation or displacement of the first metal part 10a and the second metal part 10b during the injection process, thereby improving the injection molding yield.
[0038] Furthermore, such as Figure 4 and Figure 5As shown, there are two first inserts and two second inserts, and the first inserts and second inserts are set in a one-to-one correspondence. Two receiving slots are formed between each first insert and the second insert. Each receiving slot contains a set of first metal parts 10a and second metal parts 10b stacked together. That is, one product can be injection molded in each receiving slot. In other words, four sets of first metal parts 10a and second metal parts 10b can be injection molded simultaneously in one injection process, which means that four products can be produced simultaneously, thus improving production efficiency.
[0039] The aforementioned injection mold 10 for communication structural components has a first insert 300 disposed within the upper mold core 110 and a second insert 400 disposed within the lower mold core 210. The first insert 300 and the second insert 400 together form a receiving groove. Before injection molding, the first metal part 10a and the second metal part 10b are stacked and placed within the receiving groove. When the moving plate 510 moves under the drive of the cylinder, it drives the first limiting post 520 and the second limiting post 530 to move together, so that the first limiting post 520 passes through the first and third clearance holes in sequence, and the second limiting post 530 passes through the... The second and fourth clearance holes ensure that the end of the first limiting post 520 is located within the limiting hole of the first metal part 10a, and the end of the second limiting post 530 is located within the limiting hole of the second metal part 10b. When molten injection liquid is injected into the injection cavity, the first limiting post 520 fixes the first metal part 10a, and the second limiting post 530 fixes the second metal part 10b. This ensures a better fixing effect for the first metal part 10a and the second metal part 10b, thus preventing displacement or deformation of the first metal part 10a and the second metal part 10b during the injection molding process.
[0040] In one embodiment, the injection cavity is located at the end of the first insert 300 or the second insert 400. In this embodiment, the first insert 300 and the second insert 400 have a receiving groove formed in the middle, the first metal part 10a and the second metal part 10b are located in the middle receiving groove, and the two ends of the first metal part 10a and the second metal part 10b are fixed by injection molding, that is, the ends of the first insert 300 and the second insert 400 together with the upper mold core 110 and the lower mold core 210 form an injection cavity, and the injection mold is formed in the injection cavity so that the injection mold at both ends fixes the first metal part 10a and the second metal part 10b.
[0041] In one embodiment, the first limiting post is cylindrical. It is understood that the limiting hole of the first metal member is circular, and the first limiting post is cylindrical to fit the shape of the limiting hole of the first metal member, thereby allowing the end of the first limiting post to be inserted into the limiting hole of the first metal member.
[0042] In one embodiment, the second limiting post is rectangular. It is understood that the limiting hole of the second metal member is rectangular, and the second limiting post is rectangular, to fit the shape of the limiting hole of the second metal member, thereby allowing the end of the second limiting post to be inserted into the limiting hole of the second metal member.
[0043] like Figure 5 As shown, in one embodiment, there are multiple first limiting posts 520, and the multiple first limiting posts 520 are arranged at intervals along the length of the moving plate 510. It can be understood that there are multiple first limiting posts 520, and each first limiting post 520 is embedded in the limiting hole of the first metal part 10a, so as to achieve a better fixing and limiting effect on the first metal part 10a.
[0044] like Figure 5 As shown, in one embodiment, there are multiple second limiting posts 530, which are spaced apart along the length of the moving plate 510. It is understood that the multiple second limiting posts 530, with each second limiting post 530 corresponding to a limiting hole in the second metal part 10b, provides a better fixing and limiting effect on the second metal part 10b.
[0045] In one embodiment, the first limiting post 520 is located in the middle of the movable plate 510, and the second limiting post 530 is located at the periphery of the movable plate 510. It is understood that the limiting hole of the first metal part 10a is located in the middle, the middle of the second metal part 10b is a hollow area, and the limiting hole of the second metal part 10b is located at its periphery. Thus, the first limiting post 520 located in the middle can pass through the hollow area of the second metal part 10b and be embedded in the limiting hole of the first metal part 10a, while the second limiting post 530 located at the periphery is embedded in the limiting hole of the second metal part 10b.
[0046] like Figure 5As shown, in one embodiment, the movable plate assembly 500 further includes an ejector post 540, which is mounted on the movable plate 510. The lower mold core 210 has a first through hole, and the second insert 400 has a second through hole. The first through hole and the second through hole are correspondingly arranged. The ejector post 540 is used to move and pass through the first through hole and the second through hole in sequence, so that the ejector post abuts against the second metal part 10b and ejects the second metal part 10b out of the receiving groove. In this embodiment, after the injection molding cavity has been filled with an injection molded part, the mold needs to be opened. At this time, the movable plate 510 moves upward, and the ejector post 540 also moves upward under the drive of the movable plate 510. The ejector post abuts against the periphery of the second metal part 10b, so that when the ejector post 540 moves upward, it pushes the second metal part 10b and the first metal part 10a upward, thereby pushing the first metal part 10a and the second metal part 10b out of the receiving groove to complete the demolding process.
[0047] In one embodiment, the first insert is screwed to the upper mold core, and the second insert is screwed to the lower mold core. In this embodiment, the first insert is screwed to the upper mold core, meaning the first insert and the upper mold core are detachably connected, making the disassembly and replacement of the first insert more convenient. Furthermore, the second insert is screwed to the lower mold core, making the disassembly and replacement of the second insert more convenient.
[0048] like Figure 5 As shown, in one embodiment, the movable plate 510 is provided with a guide post 511, the lower mold 200 has a guide hole, the guide post 511 is fitted with an elastic element 512, and the elastic element 512 is connected to the lower mold 200 so that the guide post 511 is telescopically disposed within the guide hole. In this embodiment, the elastic element 512 is a spring, one end of which is connected to the lower mold 200, and the other end abuts against the movable plate 510. The spring is fitted with the guide post 511. When the cylinder drives the movable plate 510 to move upward, the guide post 511 moves along the guide hole. At this time, the spring is compressed to play a buffering role, that is, the force on the first metal part 10a and the second metal part 10b is small. When the spring is relaxed, the movable plate 510 is reset.
[0049] This application also provides an injection molding apparatus, including the injection mold 10 for communication structural components as described in any of the above embodiments.
[0050] Compared with the prior art, this disclosure has at least the following advantages:
[0051] The aforementioned injection mold 10 for communication structural components has a first insert 300 disposed within the upper mold core 110 and a second insert 400 disposed within the lower mold core 210. The first insert 300 and the second insert 400 together form a receiving groove. Before injection molding, the first metal part 10a and the second metal part 10b are stacked and placed within the receiving groove. When the moving plate 510 moves under the drive of the cylinder, it drives the first limiting post 520 and the second limiting post 530 to move together, so that the first limiting post 520 passes through the first and third clearance holes in sequence, and the second limiting post 530 passes through the... The second and fourth clearance holes ensure that the end of the first limiting post 520 is located within the limiting hole of the first metal part 10a, and the end of the second limiting post 530 is located within the limiting hole of the second metal part 10b. When molten injection liquid is injected into the injection cavity, the first limiting post 520 fixes the first metal part 10a, and the second limiting post 530 fixes the second metal part 10b. This ensures a better fixing effect for the first metal part 10a and the second metal part 10b, thus preventing displacement or deformation of the first metal part 10a and the second metal part 10b during the injection molding process.
[0052] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
