Description

Technical Field

[0001] This utility model relates to the field of fixtures and tooling, specifically to an integrated injection molding tooling for high-speed copper cables. Background Technology

[0002] In the manufacturing process of high-speed copper cables, injection molding is used to fix the wire cores with the same function inside the cable, facilitating soldering connections between the wire cores and corresponding pins on the PCBA board. Traditional injection molding fixtures generally suffer from problems such as insufficient wire core positioning accuracy, uneven distribution of injection material, and low production efficiency when handling multi-core structures of high-speed copper cables.

[0003] Existing injection molding fixtures mostly use simple clamps or mold cavities to fix the wire cores, making it difficult to achieve precise spatial positioning of multiple wire cores. During the injection molding process, the wire cores are prone to displacement or crossing, leading to unstable electrical performance of high-speed copper cables and degraded signal transmission quality. Furthermore, the lack of effective constraints on the arrangement direction and spacing of the wire cores fails to meet the stringent structural precision requirements of high-speed copper cables.

[0004] For example, the multi-core cable mold disclosed in patent application number 202220339052.1, which combines multiple injection molding processes into a single molding process, does not clamp the starting end of the cable during the injection molding process. This means that when fixing the injection parts of each group of cores, each group of cores needs to be aligned and installed into the molding hole, which is a very troublesome operation. High-speed copper cables contain multiple cores, which are divided into several groups according to different requirements during transmission. Each group of cores has a different function and a different number of cores. However, the cores in each group are not separated during the injection molding process, which makes it easy to generate the risk of overflow during the later injection molding process. Summary of the Invention

[0005] One object of this invention is to solve at least the aforementioned problems and / or defects, and to provide at least the advantages described below.

[0006] In order to achieve these objectives and other advantages of the present invention, an integrated injection molding tooling for high-speed copper cables is provided, comprising: an injection molding assembly for fixing and installing each group of cores of the high-speed copper cable, and a clamping assembly for fixing the starting ends of each group of cores of the high-speed copper cable.

[0007] The injection molding assembly includes: an injection molding upper cover and an injection molding lower cover that are movably connected. On the contact surfaces of the injection molding lower cover and the injection molding upper cover, multiple sets of guide grooves are respectively provided to limit each set of wire cores of the high-speed copper cable, and each set of guide grooves is in the shape of a comb in space.

[0008] The injection-molded top cover has multiple injection ports I that communicate with an external injection molding machine. Each guide groove group has an injection groove in the middle that is perpendicular to the cable direction. Each injection port I and the corresponding injection groove are spatially connected.

[0009] Preferably, it also includes: a support plate disposed on the injection molding cover, wherein the support plate has positioning holes on both sides for the connecting post on the surface of the injection molding cover to extend into, and an injection port II communicating with an external injection molding machine is provided in the middle of the support plate.

[0010] The injection-molded top cover has a strip-shaped groove on its surface that communicates with injection port II. The injection port I is distributed in the strip-shaped groove and communicates with the corresponding injection groove. The injection port I has a conical structure in space.

[0011] Preferably, the clamping fixture includes: a base for installing the starting end of the wire core of the high-speed copper cable, wherein the base is provided with a plurality of grooves that match each wire core;

[0012] A cover plate is hinged to one side of the base, and a buckle is hinged to the other side of the base to secure the closed cover plate.

[0013] Preferably, a flexible layer is provided on the contact surface between the cover plate and the base.

[0014] Preferably, it further includes: a fixing seat disposed at the bottom of the injection-molded lower cover, wherein the fixing seat is detachably connected to the injection-molded lower cover;

[0015] The injection-molded lower cover has extension ends on both sides.

[0016] This invention offers at least the following advantages: The comb-shaped guide groove enables precise spatial positioning of multiple wire cores, preventing core displacement or crossing during injection molding, ensuring stable electrical performance of the high-speed copper cable, and meeting stringent structural precision requirements. The partitioned injection groove, combined with multiple injection ports I, optimizes the flow path of the injection material, reduces the risk of overflow, improves material distribution uniformity, reduces internal product defects, and extends service life. Simultaneously, the clamping assembly clamps the starting ends of each group of wire cores, facilitating the organization and orderly installation of the rear ends of each group.

[0027] like Figure 1 The high-speed copper cable integrated injection molding tooling shown includes: an injection molding assembly 2 for fixing and installing each group of cores 19 of the high-speed copper cable, and a clamping assembly 1 for fixing the starting end of each group of cores 19 of the high-speed copper cable.

[0028] The injection molding assembly 2 includes: an injection molding upper cover 4 and an injection molding lower cover 3 that are movably connected. On the contact surfaces of the injection molding lower cover 3 and the injection molding upper cover 4, there are multiple sets of guide grooves 5 that limit each set of wire cores 19 of the high-speed copper cable, and each set of guide grooves 5 is in the shape of a comb in space.

[0029] The injection-molded top cover 4 has multiple injection ports I6 that communicate with an external injection molding machine. Each guide groove group 5 has an injection groove 7 perpendicular to the cable direction in the middle. Each injection port I6 and the corresponding injection groove 7 are spatially connected.

[0030] Working principle:

[0031] When this high-speed copper cable integrated injection molding fixture is in operation, the starting ends of each group of cores 19 of the high-speed copper cable are first fixed by the clamping component 1 to ensure their stability and prevent displacement during the injection molding process. Simultaneously, clamping the starting ends of the cores facilitates the arrangement and organization of the rear ends of each group of cores 19. Next, the parts of each group of cores 19 to be injected are placed into the comb-shaped guide groove group 5 of the injection molding lower cover 3. The injection molding upper cover 4 is then closed, and the guide groove group 5 of the upper cover cooperates with the lower cover to further define the position of the cores in space, forming a closed cable positioning space. Subsequently... An external injection molding machine injects molten injection material through injection port I6 of the injection cover 4. The injection material flows into the corresponding injection groove 7 through injection port I6. Since the injection groove 7 is perpendicular to the cable direction and is located on each guide groove group 5, the molten material will fill along the gaps of the injection groove 7 and wrap each group of wire cores 19 of the high-speed copper cable. After cooling and solidification, the high-speed copper cable is integrated into an injection molded form. The integration of each group of wire cores 19 through injection molding makes it easy for the wire cores 19 in the cable to not be scattered when soldered to the corresponding pins of the external PCBA board.

[0032] The above technical solution also includes: a support plate 8 provided on the injection molded cover 4, with positioning holes on both sides of the support plate 8 for the connecting post 9 on the surface of the injection molded cover 4 to extend into, and an injection port II 10 communicating with an external injection molding machine in the middle of the support plate 8.

[0033] The injection-molded top cover 4 has a strip-shaped groove 11 on its surface that communicates with the injection port II 10. The injection ports I 6 are distributed within the strip-shaped groove 11 and communicate with the corresponding injection ports 7. The injection ports I 6 have a conical structure in space. Using this technical solution, during operation, the support plate 8 is precisely positioned and installed on the connecting post 9 on the surface of the injection-molded top cover 4 through positioning holes on both sides. The injection material from the external injection molding machine is injected through the injection port II in the middle of the support plate 8. The injected material is diverted through the strip-shaped groove 11 on the surface of the injection-molded top cover 4. Because the injection ports I 6 are distributed within the strip-shaped groove 11 and have a conical structure, the injection material can flow efficiently and evenly into the corresponding injection ports 7 at a specific flow rate and pressure. This material then fully wraps and fixes the high-speed copper cable cores 19 within the injection ports 7 of the injection-molded bottom cover 3 and the injection-molded top cover 4. After cooling and solidification, the integrated injection molding of the high-speed copper cable is completed.

[0034] In the above technical solution, the clamping fixture includes: a base 12 for installing the starting end of the wire core of the high-speed copper cable, and the base 12 is provided with a plurality of grooves 13 that match each wire core;

[0035] A cover plate 14 is hinged to one side of the base 12, and a buckle 15 is hinged to the other side of the base 12 to fix the closed cover plate 14. Using this technical solution, when the clamping fixture is in operation, the cover plate 14 and buckle 15 are first opened, and the starting end of the high-speed copper cable core is placed in the corresponding grooves 13 of the base 12. The shape of the grooves 13 matches the core, allowing for initial positioning of the core. Then, the cover plate 14 is rotated around the hinge to close, covering the base 12 and limiting the starting end of the high-speed copper cable core. Finally, the buckle 15 is rotated around the hinge to lock the closed cover plate 14, ensuring a tight fit between the cover plate 14 and the base 12, thus firmly clamping the starting end of the high-speed copper cable core. This ensures that the core remains stable during injection molding and does not shift or loosen.

[0036] In the above technical solution, a flexible layer 16 is provided on the contact surface between the cover plate 14 and the base 12. Using this technical solution, the flexible layer 16 is made of silicone material. The flexible silicone layer 16 directly contacts the wire core and sheath, increasing friction and ensuring the stability of the clamping assembly 1 in clamping the cable.

[0037] The above technical solution also includes: a fixing seat 17 disposed at the bottom of the injection-molded lower cover 3, wherein the fixing seat 17 is detachably connected to the injection-molded lower cover 3; wherein extension ends 18 are provided on both sides of the injection-molded lower cover 3. Using this technical solution, in actual operation, the high-speed copper cable contains multiple cores, which are divided into several groups. Each group of cores has a different function and a different number of cores. Based on the required number of cores 19 in each group of the high-speed copper cable, a matching injection-molded assembly 2 can be selected. The injection-molded lower cover 3 of the injection-molded assembly 2 is detachably connected to the fixing seat 17. The extension ends 18 provided on both sides of the injection-molded lower cover 3, with a top-smaller and bottom-larger design, facilitate disassembly of the injection-molded lower cover 3, saving casting time.

[0038] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
