[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1 to 5 . The injection mold of the plug shell includes a pin plate 1, an ejector 2, a hydraulic slider assembly 3, a rear mold core 4, a panel 5, a runner plate 6, an A plate 7, a B plate 8, a support plate 9, a square iron block 10 and a bottom plate 20 arranged in sequence from top to bottom. A front mold core 30 is provided below the A plate 7, and a rear mold core 40 is provided above the B plate 8. The front mold core 30 and the rear mold core 40 are arranged correspondingly and form a cavity. The hydraulic slider assembly 3 is provided on the B plate 8 and is arranged correspondingly to the cavity. The pin plate 1 is provided on the inner side of the square iron block 10. One end of the pin 2 is fixed on the pin plate 1, and the other end can penetrate the support plate 9 and the B plate 8 and then extend into the cavity. The hydraulic slider assembly 3 includes a slider 31, and the slider 31 can extend into the cavity. One end of the rear mold core 4 is fixed on the support plate 9, and the other end can extend into the cavity and cooperate with the slider 31.

[0020] In the actual production process, there are two cavities, which is conducive to improving the injection molding efficiency of the product. When the plug shell injection mold is injected, the slider 31 is inserted from the side to one side of the cavity, and then the rear mold core 4 is inserted into the cavity from the bottom, and the top of the rear mold core 4 is inserted into the slider 31; after the mold is closed, the plug shell (such as Figure 6 The mold is then opened and the product is taken out.

[0021] The plug housing injection mold of the present invention also includes a first spring 50. A first mounting slot 81 is defined at the bottom end of the B-plate 8, and a second mounting slot 91 is defined at the top end of the support plate 9. One end of the first spring 50 is positioned within the first mounting slot 81, and the other end is positioned within the second mounting slot 91. Therefore, the first and second mounting slots 81 and 91 facilitate the installation of the first spring 50. When the mold is in the closed position, the bottom end of the B-plate 8 is pressed against the top end of the support plate 9, compressing the first spring 50. When the mold is opened, the rebound force of the first spring 50 pushes the B-plate 8 upward.

[0022] The plug shell injection mold also includes a pull plate 60, one end of which is fixed on the A plate 7, and the pull plate 60 is located on the outside of the A plate 7. A sliding groove 601 is provided on the pull plate 60, and a connecting pin 70 is fixed on the outside of the B plate 8. One end of the connecting pin 70 is located in the sliding groove 601 and can move along the sliding groove 601. The sliding groove 601 is set vertically.

[0023] The plug housing injection mold also includes a second spring 80, one end of which abuts against plate A 7 and the other end against runner plate 6. Consequently, when the mold is opened, the rebound force of second spring 80 forces runner plate 6 and plate A 7 to move a certain distance apart, facilitating the removal of the sprue between them and facilitating the injection molding of the next product.

[0024] The hydraulic slider assembly 3 also includes a hydraulic cylinder 32 and a moving block 33. The cylinder body of the hydraulic cylinder 32 is fixed to the outside of the B plate 8. The moving block 33 is located on the B plate 8. The slider 31 is connected to the moving block 33. Specifically, the extension and contraction of the hydraulic cylinder 32 can drive the moving block 33 to move. The slider 31 moves along with the moving block 33, facilitating the movement of the slider 31.

[0025] The front end of the slider 31 is provided with a through hole, and the rear mold core 4 can pass through the through hole. Thereby, when the rear mold core 4 is convenient to extend upward into the mold cavity, the top end is inserted into the through hole of the slider 31, which is convenient for the molding of the corresponding structure of the product.

[0026] The plug housing injection mold of the present invention also includes a return spring 11 and a mounting rod 12. One end of the mounting rod 12 is fixed to the ejector plate 1, and the other end can pass through the support plate 9. The return spring 11 is sleeved on the mounting rod 12, with one end of the return spring 11 abutting the ejector plate 1 and the other end abutting the support plate 9. Therefore, when the product is injection-molded, the ejector plate 1 moves upward. At this time, the return spring 11 is compressed by the ejector plate 1 and the support plate 9. When the product is ejected by the ejector, the rebound force of the return spring 11 pushes the ejector plate 1 downward, thereby achieving the reset of the ejector plate 1 and the ejector 2.

[0027] The specific opening and closing process of the plug shell injection mold of the utility model is as follows:

[0028] During mold closing, hydraulic cylinder 32 first pushes slider 31 toward the mold cavity. Once slider 31 is in place, face plate 5, runner plate 6, and plate A 7 move toward plate B 8, gradually pressing against plate B 8. Under the downward force of plate A 7, plate B 8 gradually moves toward support plate 9. At this point, rear mold core 4 is positioned upward relative to plate B 8, allowing it to be inserted into the mold cavity and engage slider 31, completing mold closing. After mold closing, glue is injected into the mold cavity to form the final plug housing.

[0029] After the product injection molding is complete, the mold is opened. During the mold opening process, an external force first moves the faceplate 5, runner plate 6, and A-plate 7 upward, separating A-plate 7 from the molded product. After A-plate 7 separates from the product, the rebound force of the second spring 80 separates A-plate 7, facilitating the removal of the sprue. As A-plate 7 moves upward, the clamping force acting on B-plate contacts the mold. At this point, the rebound force of the first spring 50 pushes B-plate 8 upward, allowing the rear mold core 4 to be withdrawn from the through-hole of the slider 31. As A-plate 7 continues to move upward, it drives the pull plate 60 upward with it. When the bottom end of the sliding groove 601 moves to the connecting pin 70, the pull plate 60 acts on the connecting pin 70, forcing the connecting pin 70 and B-plate 8 upward along with the pull plate 60, allowing the rear mold core 4 to be ejected from the mold cavity and demolded. When the rear mold core 4 is released from the slider 31, the piston rod of the hydraulic cylinder 32 pulls back, thereby withdrawing the slider 31 from the mold cavity and separating it from the product. When the A plate 7 opens upward to its full position, the B plate 8 stops moving upward. At this time, the ejector plate 1 drives the ejector pin 2 upward, ejecting the product from the mold cavity through the ejector pin 2, completing the demolding.

[0030] The above are only preferred embodiments of the present invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
