The opening of the receiving cavity 120 is formed on the working surface 110, and the bottom of the receiving cavity 120 is provided with a first connecting part 130.

[0037] Specifically, the working surface 110 is actually the contact surface of the template body 100 when it is closed.

[0038] The mold core body 200 is located in the receiving cavity 120 (not shown in the figure), and the mold core body 200 is provided with a second connecting part 210, at least part of the second connecting part 210 being close to the first connecting part 130.

[0039] The connector 300 connects the second connecting part 210 and the first connecting part 130, thereby connecting the mold core body 200 and the template body 100.

[0040] Specifically, the first connecting part 130, the second connecting part 210, and the connector 300 are not specifically limited here.

[0041] It is worth noting that in the current technology, the injection mold requires the template to be processed with lifting holes, and the disassembly and assembly are very inconvenient when the workpiece is actually manufactured through the injection mold.

[0042] In this embodiment, the connector 300 connects the second connecting part 210 and the first connecting part 130, thereby connecting the mold core body 200 and the template body 100. This eliminates the need for machining the lifting mold hole and facilitates the assembly and disassembly of the mold core body 200 and the template body 100, saving time for fitters. At the same time, the front-locking template assembly has a simple structure and is easy to manufacture.

[0043] like Figures 1-5 As shown, based on the above embodiment, the first connecting part 130 is configured as a threaded hole, the second connecting part 210 is configured as a through hole, the connecting member 300 is configured as a screw, and the connecting member 300 passes through the second connecting part 210 and is threadedly connected to the first connecting part 130.

The tail of the connector 300 is threadedly connected to the first connecting part 130, and the head of the connector 300 contacts the mold core body 200 and presses the mold core body 200 onto the template body 100.

[0045] like Figures 1-5As shown, based on the above embodiment, the second connecting part 210 is provided with a countersunk hole 211 at one end away from the first connecting part 130, the tail of the connector 300 is threadedly connected to the first connecting part 130, and the head of the connector 300 is located in the countersunk hole 211.

[0046] Specifically, the height of the head of the connector 300 is less than or equal to the depth of the countersunk hole 211.

[0047] In this embodiment, the second connecting part 210 is provided with a countersunk hole 211 at the end away from the first connecting part 130. The tail of the connector 300 is threadedly connected to the first connecting part 130. The head of the connector 300 is located in the countersunk hole 211. The head of the connector 300 is sunk into the countersunk hole 211 and does not protrude from the working surface 110, which can prevent collision with the mold and is not easily damaged.

[0048] Specifically, the shape of the countersunk hole 211 is not specifically limited; it can be square, hexagonal, circular, or other shapes.

[0049] The countersunk hole 211 is preferably circular in shape.

[0053] In this embodiment, the drive groove 310 provided in the connector 300 can be driven by a drive tool, and rotated by the drive tool to pass through the second connecting part 210 and be screwed into the first connecting part 130. Since it is driven by the drive groove 310, the diameter of the countersunk hole 211 only needs to be slightly larger than the diameter of the connector 300 so that it is not easy to get stuck.

[0054] like Figures 1-5 As shown, based on the above embodiment, the height of the mold core is less than or equal to the depth of the receiving cavity 120.

[0055] In this embodiment, the height of the mold core is less than or equal to the depth of the receiving cavity 120, and the mold core does not protrude from the working surface 110 to prevent mold collision.

[0058] In this embodiment, the disassembly grooves 121 provided at the four corners of the receiving cavity 120 facilitate the removal of the connector 300 by the fitter, and then the removal of the mold core body 200 from the template body 100 through the disassembly grooves 121.

[0059] like Figures 1-5 As shown, based on the above embodiment, the number of the first connecting part 130 and the second connecting part 210 is the same and there are at least two of each.

[0060] Four of the first connecting parts 130 are located at the four corners of the bottom of the receiving cavity 120, and four of the second connecting parts 210 are located at the four corners of the mold core body 200.

[0061] Specifically, the four first connecting parts 130 correspond one-to-one with the four second connecting parts 210.

[0062] In this embodiment, four first connecting parts 130 are located at the four corners of the bottom of the receiving cavity 120, and four second connecting parts 210 are located at the four corners of the mold core body 200, which increases the accuracy of the mold core body 200 being installed on the template body 100 and the yield rate of the finished product.

[0063] like Figures 1-5 As shown, based on the above embodiments, the mold core body 200 is also provided with two cavities 220.

[0064] The other two first connecting parts 130 are located on both sides of the receiving cavity 120 parallel to the distribution direction of the two cavities 220, and are both located between the two cavities 220. The other two second connecting parts 210 are located on both sides of the mold core body 200 parallel to the distribution direction of the two cavities 220, and are both located between the two cavities 220.

[0065] Specifically, the positions of the two first connecting parts 130 and the two second connecting parts 210 correspond one-to-one.

[0066] In this embodiment, both first connecting parts 130 are located between the two cavities 220, and both second connecting parts 210 are located between the two cavities 220. Therefore, it can effectively prevent warping, increase the accuracy of the mold core body 200 being installed on the template body 100, and further increase the yield of the finished product.
