[0037] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0038] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0039] Please combine Figures 1 to 6 , the mold provided by the utility model is now described.

[0040] The mold includes a base plate 1, a template 2, a driving component 3 and an inserting pin 4. The template 2 is installed on the base plate 1. The template 2 is provided with a through hole 201. The inserting pin 4 passes through the through hole 201 and cooperates with the hole wall of the through hole 201 to form a molding cavity of the product. The driving component 3 is installed on the base plate 1 and is connected to the inserting pin 4. The driving component 3 drives the inserting pin 4 to move, and the inserting pin 4 can drive the product to leave the molding cavity.

[0041] It can be understood that the template 2 of the mold is installed on the base plate 1, the template 2 is provided with a through hole 201, the insert pin 4 passes through the through hole 201, and cooperates with the hole wall of the through hole 201 to form a molding cavity of the product, the driving component 3 is installed on the base plate 1 and connected to the insert, the driving component 3 drives the insert pin 4 to move, and the insert pin 4 can drive the product out of the molding cavity, so that the product can be easier to demold and is not easy to stick to the template 2, thereby improving the quality of the product.

[0042] It should be noted that the mold includes a rear template 2 and a front template 2 , and the driving component 3 and the insert pin 4 are arranged on the rear template 2 .

[0043] It should be supplemented that the insert pin 4 has a cross groove, and the groove wall of the cross groove cooperates with the hole wall of the through hole 201 to form a forming cavity for the cross reinforcement rib.

[0044] In this embodiment, the driving assembly 3 includes a cartridge 31, an ejector plate 32 and an elastic member 33. There is a moving space 100 between the template 2 and the bottom plate 1. The cartridge 31 abuts against the ejector plate 32 and is connected to the insert pin 4. The cartridge 31 is provided with a receiving cavity 311. The elastic member 33 is installed in the receiving cavity 311 and elastically abuts against the bottom plate 1. Specifically, the elastic member 33 is a spring.

[0045] During the mold opening process, the ejector plate 32 moves in the moving space 100, and the elastic deformation force of the elastic member 33 acts on the cartridge 31, driving the cartridge 31 to move, and the cartridge 31 drives the insert pin 4 to move. In the initial state, the ejector plate 32 abuts against the cartridge 31, so that the cartridge 31 and the bottom plate 1 compress the elastic member 33, thereby causing the elastic member 33 to undergo elastic deformation. During the mold opening process, the ejector plate 32 moves, and the elastic deformation force of the elastic member 33 acts on the cartridge 31, so that the cartridge 31 moves in the moving space 100 along with the ejector plate 32, and the cartridge 31 then drives the insert pin 4 to move in the through hole 201, so that the insert pin 4 can push the product out of the molding cavity.

[0046] Of course, in other embodiments, the driving assembly 3 may be a driving cylinder, which drives the inserting needle 4 to move so that the inserting needle 4 can push the product out of the molding cavity.

[0047] Furthermore, the arrangement direction of the cartridge 31 is parallel to the movement direction of the mold opening, so that the elastic deformation force of the elastic member 33 can all act on the insert pin 4, thereby making it easier for the insert pin 4 to push the product out of the molding cavity.

[0048] In one embodiment, if Figure 4 and Figure 5 As shown, the drive assembly 3 also includes a connecting member 5, and the cartridge 31 is connected to the insert pin 4 via the connecting member 5. By providing the connecting member 5, the length of the insert pin 4 can be shortened, so that the rigidity of the insert pin 4 is higher and it is not easy to break.

[0049] In this embodiment, the connecting member 5 is provided with an opening 51 and a connecting groove 52 communicating with the opening 51, and the insert pin 4 is provided with a snap-fit ​​block 41, which snaps into the connecting groove 52 from the opening 51. The snap-fit ​​block 41 can enter the connecting groove 52 from the opening 51 and snap into the connecting groove 52, so that the insert pin 4 and the connecting member 5 can be detachably connected, so as to facilitate the replacement of the insert pin 4.

[0050] In one embodiment, if Figure 4 As shown, the mold further includes a guide sleeve 6, which is mounted on the template 2 and sleeved with a connector 5. By providing the guide sleeve 6, the connector 5 can move along the direction of the guide sleeve 6, thereby guiding the moving direction of the connector 5.

[0051] In one embodiment, if Figure 5 and Figure 6As shown, the insert needle 4 includes a first insert 42, a second insert 43 and a mounting member 44. The first insert 42 is provided with a first mounting hole. The mounting member 44 passes through the first mounting hole and is connected to the second insert 43. Specifically, the mounting member 44 can be a bolt. The mounting member 44 is threadedly connected to the first mounting hole and is threadedly connected to the second insert 43, so that the first insert 42 and the second insert 43 can be connected.

[0052] In this embodiment, two mounting members 44 are provided and are arranged at intervals in the extension direction of the first insert 42. By providing two mounting members 44, the stability of the connection between the first insert 42 and the second insert 43 can be increased.

[0053] Furthermore, the first insert 42 is provided with a snap-fit ​​protrusion 421, and the second insert 43 is provided with a snap-fit ​​groove 431, and the snap-fit ​​protrusion 421 is snap-fitted in the snap-fit ​​groove 431. During the installation process of the first insert 42 and the second insert 43, the snap-fit ​​protrusion 421 can be snap-fitted in the snap-fit ​​groove 431, so that the first insert 42 and the second insert 43 are pre-installed.

[0054] In one embodiment, if Figure 1 As shown, the mold further includes a first ejector rod and a straight ejector block 7 connected to the first ejector rod. The first ejector rod is connected to an ejector pin plate 32. The ejector pin plate 32 drives the first ejector rod to move, and the first ejector rod drives the straight ejector block 7 to eject the product. The ejector pin plate 32 drives the first ejector rod to move, and the first ejector rod drives the straight ejector block 7 to move, so that the straight ejector block 7 can eject the product.

[0055] In this embodiment, the mold further includes a second ejector pin and an ejector pin 8 connected to the second ejector pin. The second ejector pin is connected to an ejector pin plate 32.
