This method is not only inefficient but also poses safety hazards under the high temperature and pressure of the injection molding environment, potentially causing injury to operators. Therefore, there is an urgent need for an automated wire connector injection molding device that can improve production efficiency, ensure operational safety, and stably clamp the wires to meet the demands of modern production.

[0038] The following is for reference. Figures 1-4 A wire connector injection molding apparatus is described in detail with reference to a specific embodiment. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.
[0039] like Figures 1-4 As shown, a wire connector injection molding device mainly consists of a mold assembly and a loading / unloading assembly. The mold assembly includes a lower mold plate 100 and an upper mold plate 110. The lower mold plate 100 has a lower mold cavity 120, and the upper mold plate 110 has a corresponding upper mold cavity 130, ensuring that the wire connector can be accurately shaped during injection molding. A lower fixing groove 140 is provided next to the lower mold cavity 120, and an upper fixing groove 150 is provided at a corresponding position in the upper mold cavity 130, for installing and fixing the loading / unloading assembly. The loading / unloading assembly includes a fixing block 160, a horizontal moving mechanism 170, and a lifting mechanism 180. The fixing block 160 is installed between the lower fixing groove 140 and the upper fixing groove 150, and has a fixing hole 190 inside. The fixing hole 190 has a mounting hole 200 on its side. A first clamping cylinder 210 and a first clamping block 220 are arranged in the mounting hole 200 for clamping the wire end. The horizontal moving mechanism 170 is driven by a hydraulic rod to ensure that the fixed block 160 can move accurately in the horizontal direction. The lifting mechanism 180 uses a lifting cylinder to drive the horizontal moving mechanism 170 to lift as a whole, so as to realize the automatic loading and unloading of wires.
[0040] When the device is working, such as Figure 2 As shown, the worker only needs to place the wire into the fixing hole 190 of the fixing block 160, and the clamping cylinder will automatically clamp the wire end. Then, as... Figure 2 As shown, the horizontal moving mechanism 170 feeds the wire into the mold, as... Figure 3As shown, the lifting cylinder lowers the fixed block 160, and injection molding begins after the mold closes. After injection molding, the mold opens and the fixed block 160 rises. Simultaneously, the ejector cylinder 250 drives the ejector pin 260 to eject the finished product. Then, the horizontal moving mechanism 170 moves forward. Once the worker removes the finished product, the lead wire is reinserted, completing the automated production cycle. The entire process requires no manual operation of the mold, improving production efficiency and ensuring operational safety.
[0041] like Figure 3 As shown, the fixing block 160 has mounting holes 200 on both the upper and lower sides of the fixing hole 190. A first clamping cylinder 210 and a first clamping block 220 are installed in the lower mounting hole 200, while a second clamping cylinder 240 and a second clamping block 230 are installed in the upper mounting hole 200. It should be noted that the first clamping block 220 and the second clamping block 230 only clamp the wire end during material loading and must be released during injection molding to prevent affecting the injection molding of the wire end. The dual cylinders work together to clamp the wire end from both sides, avoiding displacement or loosening caused by unilateral clamping and ensuring stable positioning of the wire during injection molding. The lower mold plate 100 and upper mold plate 110 have multiple horizontally arranged mold cavities, and the fixing block 160 has corresponding fixing holes 190, allowing multiple wires to be clamped simultaneously for injection molding, significantly improving production efficiency. Specifically, the fixing block 160 adopts a cuboid structure, which facilitates processing and installation, while also stably supporting the clamping mechanism and ensuring uniform distribution of clamping force.
[0042] It is worth mentioning that, such as Figure 1 and Figure 2 As shown, the horizontal moving mechanism 170 drives the fixed block 160 to move horizontally via a hydraulic rod. The output end of the hydraulic rod is connected to the side of the fixed block 160, providing stable linear motion and avoiding mechanical vibration from affecting positioning accuracy. The lifting mechanism 180 uses a lifting cylinder, whose output end is connected to the bottom of the hydraulic rod, driving the horizontal moving mechanism 170 to lift as a whole, resulting in fast response and shortening loading and unloading time. Additionally, as... Figure 3 As shown, the lower mold cavity 120 has ejector pin holes at its bottom, and an ejector cylinder 250 and an ejector rod 260 are configured below the lower mold plate 100. After injection molding, the ejector cylinder 250 drives the ejector rod 260 to eject the finished product, achieving automated demolding. Furthermore, the lower mold plate 100 has guide pillars 270 on its top surface, and the upper mold plate 110 has guide sleeves 280 that mate with them on its bottom surface, ensuring precise alignment of the upper and lower mold plates 100 during mold closing. Specifically, the guide pillars 270 and guide sleeves 280 are respectively located at the four corners of the lower mold plate 100 and the upper mold plate 110, enhancing mold closing stability and preventing mold plate tilting. The upper mold plate 110 has a gating hole 290 on its top surface, directly connecting to the upper mold cavity 130, facilitating rapid injection of molten plastic, reducing runner length, improving injection efficiency, and reducing material waste.
