Description

Technical Field

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

[0002] In the field of modern electronic communication, high-speed copper cables are widely used in the connection of various devices due to their excellent signal transmission performance. A connection shell needs to be installed on the PCB board of the high-speed copper cable. The connection shell uses a snap-fit ​​method to install the PCB board inside the connection shell. This requires the injection molding of a plastic part on the cable to position and connect the connection shell. The connection shell is positioned by snapping it onto the plastic part.

[0003] In traditional high-speed copper cable high-voltage injection molding processes, the cable is typically secured manually before the injection molding assembly is activated. This method has several drawbacks. Firstly, the PCB board at the front end of the high-speed copper cable lacks effective securing measures during injection, making it prone to displacement and causing cable misalignment, affecting the cable's connection. Secondly, the cable's weight at the injection molding stage is significant, and the lack of dedicated support and restraint structures at the rear end during injection makes it prone to movement, dragging the injection position and resulting in uneven molding. This not only reduces production efficiency and produces defective products but also increases production costs. For example, a data cable connector injection molding machine fixture disclosed in patent application CN201921788192.1 fails to adequately secure the data cable's rear and front connectors during injection, leading to uneven molding due to cable vibration, resulting in defective products and increased production costs.

[0025] like Figure 1 The high-pressure injection molding platform for a high-speed copper cable shown includes: an injection molding assembly 1 for injection molding the high-speed copper cable 4, and a clamping fixture I2 for fixing the PCB board at the front end of the high-speed copper cable 4 on one side of the injection molding assembly 1, and a clamping fixture II3 for supporting and limiting the rear end cable of the high-speed copper cable 4 on the other side of the injection molding assembly 1. The clamping fixture II3 includes: a base 31, and the base 31 has a groove I32 for installing the rear end cable of the high-speed copper cable 4.

[0026] A top cover 33 is hinged to one side of the upper surface of the base 31. A groove II 34 that matches the groove I 32 is provided on the lower surface of the top cover 33. An anti-slip layer 36 that increases friction is provided on the contact surface between the groove I 32 and the groove II 34 and the high-speed copper cable 4.

[0027] The base 31 has a latch 35 hinged to one side wall to secure the closed top cover 33.

[0028] Working principle:

[0029] The PCB board at the front end of the high-speed copper cable 4 is placed in clamping fixture I2 to ensure that the PCB board does not shift during injection molding. The part of the high-speed copper cable 4 to be injected is placed in injection molding assembly 1. At the same time, the rear end of the cable is placed in groove I32 of base 31 of clamping fixture II3. The hinged top cover 33 is closed, so that groove II34 and groove I32 are closed to clamp the cable. After the top cover 33 is locked by buckle 35, the cable is stably supported at the rear end. The anti-slip layer 36 set on the contact surface of groove I32 and groove II34 increases the friction with the cable sheath and improves the fixing effect of groove I32 and groove II34 on the cable. This avoids problems such as injection offset and unevenness caused by the cable swaying due to the cable being too long and not supported during injection molding. After the cable is fixed and positioned, the injection molding machine performs injection according to the preset process parameters to complete the injection molding process of the part of the cable to be injected.

[0030] The base 31 is mounted on the injection molding platform through a mounting hole at its bottom. The buckle 35 is configured as a latch, which is a conventional technology in the mechanical field and will not be described in detail here.

[0031] In the above technical solution, the clamping fixture I2 includes: a worktable 21, the surface of the worktable 21 is provided with a plurality of snap-fit ​​grooves 22 adapted to the shape of the PCB board, and the side walls of the snap-fit ​​grooves 22 are provided with support parts 23 that abut against the lower surface of the PCB board.

[0032] One end of the snap-fit ​​groove 22 is hinged to a cover plate 24, and the lower surface of the cover plate 24 is provided with a limiting part 241 that abuts against the upper surface of the PCB board.

[0033] The workbench 21 has upwardly extending connecting ears 25 on both sides, and a limiting rod 26 that cooperates with the cover plate 24 passes between the connecting ears 25. Using this technical solution, firstly, the PCB board at the front end of the high-speed copper cable 4 is manually installed into the snap-fit ​​groove 22. Multiple protrusions on both sides of the snap-fit ​​groove 22 extend into the corresponding slots on the PCB board, restricting the movement of the PCB board in the X direction. Simultaneously, the support parts 23 on both sides of the snap-fit ​​groove 22 support the lower surface of the PCB board in a multi-point contact manner, forming a stable support plane. Then, after the hinged cover plate 24 is rotated and closed, the lower surface limiting part 241 cooperates with the support part 23 to limit the spatial position of the PCB board. Finally, the cover plate 24 is locked by the limiting rod 26 passing between the connecting ears 25.

[0034] The limiting rod 26 is made of metal, and the connecting ear 25 is equipped with a magnetic attraction part, so that the limiting rod 26 automatically maintains a stable position after being inserted into the connecting ear 25 without the need for additional tightening. The operator only needs to insert the limiting rod 26 into the connecting ear 25 and gently push it into the magnetic attraction range to complete the locking. When disassembling, a pulling force slightly greater than the attraction force can be applied to remove it, which greatly shortens the clamping time.

[0035] In the above technical solution, anti-slip layer 36 is provided on the contact surface between groove I 32 and groove II 34 and high-speed copper cable 4;

[0036] The anti-slip layer 36 is made of silicone. This technical solution increases the friction between the silicone anti-slip layer 36 and the cable sheath, improving the fixing effect of grooves I 32 and II 34 on the cable. The high elasticity of silicone allows it to tightly wrap around the copper cable sheath (even if the cable surface has slight curvature or unevenness). Through elastic deformation, it fills the tiny gaps between the grooves and the cable, increasing the actual contact area and thus enhancing friction.

[0037] The above technical solution also includes a transmission component that moves back and forth along the direction of the injection molding assembly 1, located below the worktable 21. The transmission component includes a pair of guide rails 27 located below the worktable 21, with a slider 28 slidably mounted on each guide rail 27. Each slider 28 is fixedly connected to the lower surface of the worktable 21. This technical solution allows the worktable 21 to slide back and forth along the direction of the injection molding assembly 1 by installing guide rails 27 and sliders 28 below it. This facilitates changing the injection position after the cable has been initially fixed; by moving the worktable 21 and simultaneously releasing the top cover 33, the cable can be moved back and forth, thereby changing the injection position.

[0038] In the above technical solution, a crossbeam 29 is provided at the front end of the slot 22, and a plug 291 that abuts against the PCB board is provided on the crossbeam 29; wherein, the plug 291 is made of silicone. Using this technical solution, the silicone plug 291 on the crossbeam 29 can tightly abut against the front end of the PCB board, achieving precise positioning by adhering to the edge of the PCB board with soft and elastic silicone. The soft texture of silicone will not scratch or damage sensitive components and pads on the PCB board when it abuts against it. Compared with rigid materials, the silicone plug 291 can buffer the impact force during the injection molding process, reduce physical damage to the PCB board, and protect its electrical performance and appearance integrity.

[0039] 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.
