[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Reference Figures 1-10 The connector socket housing injection mold includes an ejector plate 30, an ejector pin 40, a slider assembly 4, a pull rod 5, and, from top to bottom, a panel 6, a sprue plate 7, a front template 8, a rear template 9, a square iron 10, and a base plate 20.

[0025] A front mold core 1 is provided below the front mold plate 8, and a rear mold core 2 is provided above the rear mold plate 9. The front mold core 1 and the rear mold core 2 are arranged correspondingly to form a cavity. The ejector plate 30 is located inside the square iron 10. One end of the ejector pin 40 is fixed on the ejector plate 30, and the other end can penetrate the rear mold plate 9 and extend into the cavity. The slider assembly 4 is located outside the cavity. The front mold core 1 is provided with a first front mold insert 11 and a second front mold insert 12. The rear mold core 2 is provided with a first rear mold insert 21 and a second rear mold insert 22. The second front mold insert 12 is located on one side of the first front mold insert 11, and the first rear mold insert 21 is located on one side of the second rear mold insert 22. One end of the pull rod 5 is fixed on the ejector plate 30, and the other end can extend between the first rear mold insert 21 and the second rear mold insert 22. The first rear mold insert 21 and the second rear mold insert 22 are both arranged opposite to the first front mold insert 11.

[0026] During processing, semi-circular grooves are reserved at the joint of the first rear mold insert 21 and the second rear mold insert 22. The semi-circular grooves are joined together to form a circular hole, which facilitates the insertion of the pull rod 5 from bottom to top into the circular hole formed by the joint. The end face of the pull rod 5 can be flush with the corresponding end faces of the two rear mold inserts.

[0027] When the mold needs injection molding, the threaded part is first placed above the rear mold core 2, and then the mold is closed. When the mold is closed, the front mold core 1 and the rear mold core 2 are in close contact, and the first front mold insert 11 abuts against the first rear mold insert 21 and the second rear mold insert 22. The second front mold insert 12 is inserted into the threaded part to fix it. The slider assembly 4 is close to both sides of the cavity to complete the mold closing. Then, injection molding material is injected into the cavity to perform injection molding and obtain the connector socket shell (e.g. Figure 11 (As shown).

[0028] After injection molding is completed, the front mold plate 8 and the rear mold plate 9 separate. After the front mold plate 8 moves into place, it drives the ejector pin 40 and the pull rod 5 to move upward through the ejector plate 30. The ejector pin 40 and the pull rod 5 act on the product, pushing the product upward and realizing demolding.

[0029] The tops of the first rear mold insert 21 and the second rear mold insert 22 are both formed with limiting protrusions 50. The bottom end of the first front mold insert 11 has two limiting grooves 13, which can respectively cooperate with the corresponding limiting protrusions 50. Therefore, when the mold is closed, the first front mold insert 11 moves towards the rear mold plate 9 along with the front plate 8. After the mold is closed, the limiting protrusions 50 are inserted into the corresponding limiting grooves 13 for cooperation. Through the cooperation of the limiting protrusions 50 and the limiting grooves 13, the first front mold insert 11 can be accurately aligned with the first rear mold insert 21 and the second rear mold insert 22, ensuring the precision of the cooperation and thus ensuring the molding quality of the product.

[0030] The top of the rear mold core 2 is provided with a positioning hole 23, and the bottom of the second front mold insert 12 is provided with a tapered guide part 14, which can be inserted into the positioning hole 23.

[0031] The lower end of the second front mold insert 12 is provided with a limiting step 15, which is located above the tapered guide 14.

[0032] In actual use, the operator places the threaded part at the positioning hole 23 of the rear mold core 2. When the mold closes, the tapered guide 14 at the bottom of the second front mold insert 12 acts on the threaded part first. Through the action of the tapered guide 14, it can be guided and inserted into the threaded part, realizing the return of the threaded part to its correct position. As the second front mold insert 12 moves downward, the limiting step 15 limits the position of the threaded part on the second front mold insert 12. At this time, the tapered guide 14 is inserted into the positioning hole 23, realizing the accurate alignment of the second front mold insert 12, thus ensuring the accuracy of the threaded part's placement position each time and ensuring the injection molding quality of the product.

[0033] The slider assembly 4 includes a slider 41, a moving block 42, a guide block 43, and an inclined guide rod 44. The guide block 43 is fixed on the front template 8. One end of the inclined guide rod 44 is fixed to the front template 8, and the other end can pass through the moving block 42. The moving block 42 is located on the rear template 9. The slider 41 is connected to the moving block 42. One end of the slider 41 can extend into one side of the cavity. The inner side wall of the slider 41 is provided with a post.

[0034] The guide block 43 has a first inclined surface on its inner side and the moving block 42 has a second inclined surface on its outer side. The first inclined surface can fit into the second inclined surface.

[0035] Specifically, during the mold closing process, when the front mold plate 8 moves to the rear mold plate 9, the front mold plate 8 drives the inclined guide rod 44 to move synchronously, so that the inclined guide rod 44 is inserted into the moving block 42. Under the guidance of the inclined guide rod 44, the moving block 42 can be pushed to move towards the cavity side; the moving block 42 pushes the slider 41 to move towards the cavity side until it moves into place, so that the slider 41 is located on the corresponding side of the cavity; at the same time, the insert extends into the cavity, which facilitates the injection molding of the corresponding structure of the product.

[0036] Conversely, when the mold is opened, the front mold plate 8 moves away from the rear mold plate 9. Under the action of the inclined guide rod 44, it drives the moving block 42 and the slider 41 to move away from the cavity, thus realizing the separation of the slider 41 and the insert from the product.

[0037] During the movement of the front mold plate 8, the guide block 43 moves synchronously. When the mold is closed, the first inclined surface acts on the second inclined surface, which helps to push the moving block 42 to move smoothly to one side of the cavity. When the mold is opened, the upward movement of the guide block 43 provides enough space for the movement of the moving block 42, which facilitates the movement of the moving block 42 and the slider 41, and makes it easier for the slider 41 and the insert to separate from the product.

[0038] The connector socket housing injection mold of this utility model also includes an ejector spring 60 and a mounting rod 70. One end of the mounting rod 70 is fixed on the ejector plate 30, and the other end can pass through the rear template 9. The ejector spring 60 is sleeved on the mounting rod 70. One end of the ejector spring 60 abuts against the ejector plate 30, and the other end abuts against the rear template 9.

[0039] After the product is injected into the mold cavity, the ejector plate 30 moves the ejector pins 40 upwards, ejecting the product from the mold cavity and completing the demolding process. As the ejector plate 30 moves upwards, the ejector spring 60 is compressed. Once the product is demolded, the external force is removed, and the ejector plate 30 returns to its original position under the rebound force of the ejector spring 60, thus resetting the ejector pins 40.

[0040] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
