Description

Technical Field

[0001] This utility model belongs to the field of wire harness technology, specifically relating to a high-reliability wire harness tail clip injection molding mold. Background Technology

[0002] A wire harness is an assembly composed of multiple wires, cables, connectors, and other accessories (such as terminals, protective sleeves, and fasteners) integrated together according to specific electrical and mechanical requirements through methods such as bundling, wrapping, or injection molding. It is used to efficiently and reliably transmit power or signals in electrical systems. A wire harness end clip, also called a wire harness end clamp, is a connecting device used to fix and protect the ends of wire harnesses (such as automotive wire harnesses and industrial wire harnesses). Its main functions are to prevent detachment, loosening, waterproofing, and stress buffering, ensuring the stability and durability of the wire harness and connector interface.

[0003] The existing wire harness tail clip injection molding mold has insufficient clamping force. When injecting molten plastic under high pressure, the clamping structure of the wire harness tail clip injection molding mold cannot provide sufficient clamping force, the mold opening and closing action is unreliable, and the mold parting surface cannot fit tightly, causing plastic to overflow from the gap and form flash or burrs. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a highly reliable wire harness tail clip injection molding mold.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-reliability wire harness tail clip injection molding mold includes a moving mold frame, a moving template disposed on the moving mold frame, a moving mold core disposed within the moving template, a stationary template disposed on the moving template, a stationary mold core disposed within the stationary template, and a stationary mold base plate disposed on the stationary template. A mold cavity is formed between the moving mold core and the stationary mold core. It also includes two sets of locking mechanisms symmetrically disposed between the moving template and the stationary template. Each set of locking mechanisms includes a locking hook disposed on the stationary template, a locking module disposed on the moving template, a locking member slidably disposed on the locking module, and an elastic member. The locking module is provided with a locking groove into which the locking hook can be inserted. The elastic member is disposed between the locking member and the locking module. One end of the locking member has an unlocking pull part extending outside the locking module, and the other end of the locking member has a locking tongue part that cooperates with the locking hook. The elastic force of the elastic member causes the locking tongue part to extend into the locking groove and engage with the locking hook, thus forming a limiting fit between the locking tongue part and the locking hook.

[0006] In some embodiments, the locking tongue is provided with an unlocking ramp on the side facing the stationary template, and the locking tongue is provided with a locking plane on the side facing away from the stationary template. One end of the locking hook is provided with a hook-shaped body that cooperates with the locking tongue, and the hook-shaped body is provided with a limiting plane that abuts against the locking plane.

[0007] In some embodiments, the lock module is provided with a sliding hole communicating with the locking groove, the locking member is slidably disposed in the sliding hole, the elastic member is a spring, one end of the spring abuts against the lock tongue, and the other end of the spring abuts against the limiting step in the sliding hole.

[0008] In some embodiments, the locking member is provided with an elastic retaining ring that engages with the outer wall of the locking module for limiting.

[0009] In some embodiments, a guide component is provided between the moving template and the stationary template. The guide component includes a guide plate provided on the stationary template and a guide block provided on the moving template. The guide plate is provided with a guide groove that cooperates with the guide block. The guide block moves with the moving template and reciprocates within the guide groove.

[0010] In some embodiments, a sprue cup is provided inside the stationary mold base plate, and a positioning ring is provided on the stationary mold base plate surrounding the sprue cup.

[0011] In some embodiments, a main runner connected to the sprue cup is formed between the moving mold core and the stationary mold core. There are two mold cavities. Two branch runners are provided between the moving mold core and the stationary mold core. The two branch runners are connected between the two mold cavities and the main runner.

[0012] In some embodiments, a demolding ejector assembly is provided in the moving mold frame. The demolding ejector assembly includes a push plate slidably disposed in the moving mold frame, an ejector plate disposed on the push plate, and multiple demolding ejectors disposed on the ejector plate. The moving mold plate and the moving mold core are respectively provided with through holes through which the multiple demolding ejectors can pass. The ejector plate drives the multiple demolding ejectors to pass through the through holes and be inserted into the two mold cavities.

[0013] In some embodiments, the ejector plate is provided with multiple scrap ejector rods, and the moving mold plate and the moving mold core are respectively provided with ejector rod holes through which the multiple scrap ejector rods can pass. The ejector plate drives the multiple scrap ejector rods to pass through the ejector rod holes and insert into the main flow channel and the branch flow channel.

[0014] In some embodiments, the ejector plate is provided with a rectangular array of multiple guide posts, the upper ends of which are respectively inserted into multiple sliding holes of the moving template, and multiple compression springs are respectively fitted on the multiple guide posts to abut against the ejector plate and the moving template.

[0015] The beneficial effects of this utility model are as follows: By adding a locking mechanism between the moving template and the stationary template, the locking hook engages with the locking component when the mold is closed, thereby locking the moving template and the stationary template. This increases the locking force between the moving template and the stationary template, ensuring reliable mold opening and closing. The mold parting surface can fit tightly, preventing plastic from overflowing from the gaps and forming flash or burrs, which helps to improve the injection molding quality of the wire harness tail clip.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0026] like Figure 1-3 As shown, a high-reliability wire harness tail clip injection molding die includes a moving mold frame 1, a moving template 2 mounted on the moving mold frame 1, a moving mold core 3 disposed within the moving template 2, a stationary template 4 mounted on the moving template 2, a stationary mold core 5 disposed within the stationary template 4, and a stationary mold base plate 6 mounted on the stationary template 4. A mold cavity 100 is formed between the moving mold core 3 and the stationary mold core 5. The die also includes two sets of clamping mechanisms 7 symmetrically arranged between the moving template 2 and the stationary template 4. Each set of locking mechanisms 7 includes a locking hook 71 disposed on the stationary template 4, a locking module 72 disposed on the moving template 2, a locking member 73 slidably disposed on the locking module 72, and an elastic member. The locking module 72 is provided with a locking groove 721 into which the locking hook 71 can be inserted. The elastic member is disposed between the locking member 73 and the locking module 72. One end of the locking member 73 has an unlocking pull part 731 extending outside the locking module 72, and the other end of the locking member 73 has a locking tongue part 732 that cooperates with the locking hook 71. The elastic force of the elastic member causes the locking tongue part 732 to extend into the locking groove 721 and engage with the locking hook 71, thus forming a limiting cooperation between the locking tongue part 732 and the locking hook 71.

[0027] like Figure 2 and 3As shown, the locking tongue 732 has an unlocking ramp 7321 on the side facing the stationary template 4, and a locking plane 7322 on the side facing away from the stationary template 4. One end of the mold-locking hook 71 has a hook-shaped body 711 that cooperates with the locking tongue 732. The hook-shaped body 711 has a limiting plane 7111 that abuts against the locking plane 7322. During mold closing, the hook-shaped body of the mold-locking hook abuts against the unlocking ramp, the locking tongue retracts into the locking module, and the limiting plane of the hook engages with the locking plane of the locking tongue, thus locking the locking part with the mold-locking hook. During mold opening, the operator pulls the unlocking pull part of the locking component outwards. The locking tongue moves with the locking component and retracts into the locking module, unlocking the hook-shaped body, allowing the moving template and stationary template to perform the mold opening action. The lock module 72 has a sliding hole 722 communicating with the locking groove 721. The locking member 73 is slidably disposed within the sliding hole 722. The elastic element is a spring 74, one end of which abuts against the latch 732, and the other end abuts against a limiting step within the sliding hole 722. The locking member is slidably disposed within the sliding hole of the lock module, facilitating the assembly of the locking member and the lock module. The spring engages between the latch and the sliding hole, ensuring reliable operation of the locking member within the sliding hole. The locking member 73 has an elastic retaining ring 75 that engages with the outer wall of the lock module 72 for limiting. The elastic retaining ring serves a limiting function, facilitating the assembly of the locking member and the lock module, resulting in higher assembly efficiency.

[0028] like Figure 5 As shown, a guide assembly 8 is provided between the moving template 2 and the stationary template 4. The guide assembly 8 includes a guide plate 81 disposed on the stationary template 4 and a guide block 82 disposed on the moving template 2. The guide plate 81 is provided with a guide groove 811 that cooperates with the guide block 82. The guide block 82 moves with the moving template 2 and reciprocates within the guide groove 811. The guide assembly plays a guiding role, ensuring that the moving template and the stationary template can reliably perform mold opening and closing actions, which helps to improve the working reliability of the injection molding mold.

[0029] like Figure 1 As shown, a sprue cup 61 is provided inside the stationary mold base plate 6, and a positioning ring 62 is provided on the stationary mold base plate 6 surrounding the sprue cup 61. The positioning ring plays a positioning role and engages with the injection molding machine, which facilitates the installation of the injection molding mold and the injection molding machine, and improves installation efficiency.

[0030] like Figure 2 and 4 As shown, a main runner 101 connected to the sprue cup 61 is formed between the moving mold core 3 and the stationary mold core 5. There are two mold cavities 100, and two branch runners 102 are provided between the moving mold core 3 and the stationary mold core 5, connecting the two mold cavities 100 and the main runner 101. This dual-cavity structure design helps to improve the production efficiency of the injection molding mold.

[0031] like Figure 1 and 2 As shown, a demolding ejector assembly 9 is provided inside the moving mold base 1. The demolding ejector assembly 9 includes a push plate 91 slidably disposed within the moving mold base 1, an ejector plate 92 disposed on the push plate 91, and multiple demolding ejector pins 93 disposed on the ejector plate 92. The moving mold plate 2 and the moving mold core 3 are respectively provided with through holes through which the multiple demolding ejector pins 93 can pass. The ejector plate 92 drives the multiple demolding ejector pins 93 to pass through the through holes and insert into the two mold cavities 100. During mold opening, the demolding ejector pins of the demolding ejector assembly can eject the formed wire harness tail clips out of the mold cavity, thereby improving the production efficiency of the injection molding mold. The ejector plate 92 is respectively provided with multiple scrap ejector rods 94. The moving mold plate 2 and the moving mold core 3 are respectively provided with ejector rod holes through which the multiple scrap ejector rods 94 can pass. The ejector plate 92 drives the multiple scrap ejector rods 94 to pass through the ejector rod holes and insert into the main runner 101 and the branch runner 102. During mold opening, the ejector plate drives multiple scrap ejector pins to eject scrap from the main runner and branch runners, thereby clearing the scrap from these runners. The ejector plate 92 has multiple guide pins 95 arranged in a rectangular array. The upper ends of the guide pins 95 are inserted into multiple sliding holes in the moving platen 2, and multiple compression springs 96 are fitted onto each guide pin 95, contacting between the ejector plate 92 and the moving platen 2. The guide pins guide the moving platen, and the compression springs help the ejector pin assembly reliably reset, thus improving the demolding efficiency of the injection mold.

[0032] A locking mechanism is added between the moving and stationary mold plates. When the mold is closed, the locking hook engages with the locking component to lock the moving and stationary mold plates. This increases the locking force between the moving and stationary mold plates, ensuring reliable mold opening and closing. The mold parting surface can fit tightly, preventing plastic from overflowing from the gaps and forming flash or burrs, which helps to improve the injection molding quality of the wire harness tail clip.

[0033] The above description is only one embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model; the scope of protection of the present utility model is defined by the claims in the claims, and all equivalent changes and modifications made in accordance with the utility model are within the scope of protection of the present utility model patent.
