Description

Technical Field

[0001] This utility model belongs to the field of molds, specifically relating to a special mold for automotive high-pressure sheaths. Background Technology

[0002] Automotive high-voltage sheaths are insulating protective devices used to protect high-voltage wiring harnesses. Their structure includes a sheath body 24 and a terminal block 25 housed within the sheath body. Traditionally, the sheath body is injection molded first, and then the terminal block is riveted into the injection-molded sheath. This assembly method is not only cumbersome but also results in poor sealing. Therefore, insert injection molding is now commonly used to integrally mold the terminal block within the sheath. However, traditional insert injection molds used in automotive high-voltage sheaths typically employ a single-slider mechanism. This structure can only complete core pulling for some simple sheath structures and is difficult to complete core pulling for complex side holes. Utility Model Content

[0028] Example 1:

[0029] Reference Figure 1-10 As shown, the core-pulling slider linkage mechanism of this utility model includes: a large core-pulling slider 1, a large core-pulling slider inclined pull rod 2, a small core-pulling slider 3, and a small core-pulling slider inclined pull rod 4. The large core-pulling slider 1 is slidably disposed between large guide rails 5. The front end of the large core-pulling slider 1 has two first sliding grooves 6 arranged in an inclined direction, and the rear end of the large core-pulling slider 1 has a large pull rod inclined groove 7 in the middle. The large core-pulling slider inclined pull rod 2 is disposed within the large pull rod inclined groove 7 of the large core-pulling slider 1, and its lower inclined surface drives the large core-pulling slider 1 to slide back and forth. The small core-pulling slider 3 is slidably disposed within the first sliding groove 6 of the large core-pulling slider 1. The front end of the small core-pulling slider 3 has an injection molding cavity forming part 9, and the rear end of the small core-pulling slider 3 has a small pull rod inclined groove 10. After mold closing, the injection molding cavity forming part 9 abuts against one side of the sleeve injection molding cavity, forming a closed cavity. The inclined pull rod 4 of the small core-pulling slider is located in the inclined groove 10 of the small pull rod of the small core-pulling slider 3, and the inclined surface at its lower end drives the small core-pulling slider 3 to slide back and forth. Since the orientation of the first groove 6 is different from the sliding direction of the large core-pulling slider 1, demolding in different directions can be achieved.

[0030] Preferably, the large core-pulling slider 1 has a large core-pulling slider inclined surface positioning block 11 at its rear end, and a positioning seat 23 is provided below the large core-pulling slider inclined surface positioning block 11 for positioning and cooperation.

After mold closing, the large core-pulling slider inclined surface positioning block 11 and the small core-pulling slider inclined surface positioning block 12 are pressed down to fix the large core-pulling slider 1 and the small core-pulling slider 3 respectively, preventing their displacement and thus improving injection molding accuracy.

[0031] Preferably, a small guide rail 13 is provided on one side of the first groove 6 of the large core-pulling slider 1 to slide and engage with the small core-pulling slider 3, thereby improving the sliding stability of the large core-pulling slider 1.

[0032] Preferably, the large pull rod groove 7 of the large core-pulling slider 1 is provided with a corresponding telescopic positioning rod 14, and the rear end of the telescopic positioning rod 14 is provided with a return spring 15 and a cover 16 in sequence. After the telescopic positioning rod 14 is compressed, the large core-pulling slider inclined pull rod 2 can be installed into the large pull rod groove 7. After resetting, it can cooperate with the large core-pulling slider inclined pull rod 2 to realize the pulling of the large core-pulling slider 1.

[0033] Preferably, the front end of the large core-pulling slider 1 is provided with a set of positioning pins 17. After the mold is closed, the positioning pins 17 are positioned and engaged with the positioning holes on the mold core to improve the accuracy of the mold.

[0034] Preferably, the large core-pulling slider 1 has a second groove 18 at its front end of the first groove 6, and the lower end of the small core-pulling slider inclined rod 4 slides in conjunction with the second groove 18. This improves the sliding stability of the small core-pulling slider inclined rod 4.
