[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Reference Figures 1 to 5 The socket housing injection mold includes an ejector plate 1, an ejector 2, an inclined guide rod 3, a first slider 4, a second slider 5, and a panel 6, an upper template 7, a lower template 8, a square iron 9 and a bottom plate 10 arranged from top to bottom. A front mold core 20 is provided below the upper template 7, and a rear mold core 30 is provided above the lower template 8. The front mold core 20 and the rear mold core 30 are arranged correspondingly and form a cavity. The ejector plate 1 is provided on the inner side of the square iron 9. One end of the ejector 2 is fixed on the ejector plate 1, and the other end can penetrate the lower template 8 and extend into the cavity. A The limit block 40, the first slider 4 is located on the inner side of the limit block 40, the first slider 4 is located on both sides of the cavity, the inclined guide rod 3 is arranged obliquely, one end of the inclined guide rod 3 is fixed on the upper template 7, and the other end cooperates with the first slider 4, the second slider 5 is located above the first slider 4, a guide block 50 is provided on the panel 6, a third slider 60 is provided in the upper template 7, the second slider 5 is located on one side of the cavity, an inclined groove 601 is provided in the third slider 60, the guide block 50 cooperates with the inclined groove 601, and the second slider 5 is fixed to the third slider 60.

[0019] When the socket housing injection mold of the present invention is in the mold closing state, the front mold core 20 and the rear mold core 30 cooperate to form a cavity, and the first slider 4 and the second slider 5 are close to the cavity and correspond to the cavity, so as to facilitate the injection molding of the socket housing (such as Figure 6 shown).

[0020] The limiting block 40 is fixed to the lower template by screws. The limiting block 40 can limit the first sliding block 4 and provide a certain guide.

[0021] The socket housing injection mold of the present invention further includes a connecting plate 70, through which the inclined guide rod 3 is connected to the first slider 4. The other end of the inclined guide rod 3 can be sleeved on the connecting plate 70. The inner sidewall of the limit block 40 is inclined, and the outer sidewall of the connecting plate 70 is inclined and cooperates with the inner sidewall of the limit block. The first slider 4 is fixed to the connecting plate 70. Therefore, when the inclined guide rod 3 moves upward with the upper mold plate 7, the first slider 4 can be driven outward by the guidance of the inclined guide rod 3, so that the first slider 4 is separated from the product molded in the mold cavity, facilitating product demolding.

[0022] A mounting slot 71 is defined below the upper template 7. The width of the mounting slot 71 is greater than that of the third slider 60, and the third slider 60 is positioned within the mounting slot 71. The width of the mounting slot 71 allows for sufficient space for the movement of the third slider 60, allowing the third slider 60 to drive the second slider, allowing the second slider to be separated from the molded product, facilitating subsequent demolding.

[0023] The socket shell injection mold also includes a first spring 80, one end of which is located in the panel 6 and the other end is located in the upper template 7. Specifically, when the socket shell is being injected, the mold is in a closed mold state. At this time, the panel 6 and the upper template 7 are pressed tightly, and the first spring 80 is in a compressed state. When the product injection molding is completed and needs to be demolded, after the external locking force is removed, the panel 6 is separated from the upper template 7 under the action of the rebound force of the first spring 80, so that the upper template 7 can drive the guide block 50 to move upward. When the guide block 50 moves upward, since the guide block 50 cooperates with the inclined groove 601 of the third slider 60, the third slider 60 moves outward (i.e., away from the side of the cavity) under the guiding action of the guide block 50 moving upward, and the third slider 60 drives the second slider 5 to move outward together, so that the second slider 5 is gradually separated from the molded product.

[0024] The socket housing injection mold of the present invention also includes a second spring 90 and a mounting rod 11. One end of the mounting rod 11 is fixed to the ejector plate 1, and the other end can pass through the lower template 8. The second spring 90 is sleeved on the mounting rod 11. One end of the second spring 90 abuts against the ejector plate 1, and the other end abuts against the lower template 8.

[0025] The socket housing injection mold further includes a guide post 12 , one end of which is fixed to the panel 6 , and the other end of which can pass through the upper template 7 and the lower template 8 and extend into the square iron 9 .

[0026] The specific opening and closing process of the socket housing injection mold of the utility model is as follows:

[0027] During mold closing, the faceplate 6, upper mold plate 7, and lower mold plate 8 are all pressed together and locked by external force. Under the action of the inclined guide rod 3, the connecting plate 70 drives the first slide 4 toward the cavity. The second slide 5, under the action of the guide block 50 and the third slide 60, moves toward the cavity, completing the mold closing. After mold closing, the socket housing is injection molded, and after completion, the mold is opened.

[0028] When the mold is opened, the external clamping force is removed, and the panel 6 moves upward under the rebound force of the first spring 80, separating from the upper template 7; when the panel 6 moves upward, it drives the guide block 50 to move upward synchronously, thereby driving the third slider 60 to move outward in the installation groove 71, and the third slider 60 drives the second slider 5 to move outward, thereby separating the second slider 5 from the hook structure of the molded product. Subsequently, the upper template 7 is separated from the lower template 8, and the upper template 7 drives the inclined guide rod 3 to move upward together. Under the guidance of the inclined guide rod 3, the first slider 4 moves outward, separating the first slider 4 from the baffle structure on the outer periphery of the socket shell. When the upper template 7 moves upward into position, the ejector plate 1 moves upward, driving the ejector pin 2 to move upward, and the product is ejected from the cavity by the ejector pin 2, completing the demolding.

[0029] When the ejector plate 1 moves upward, the second spring 90 is gradually compressed; when the ejector 2 ejects the product, the ejector plate 1 is reset under the rebound force of the second spring 90, completing the reset of the ejector 2, facilitating the next product injection.

[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.
