[0043] In this embodiment, the fixing part 310 can pass through the hole of the hardware insert 520 so that the first insert 300 fixes the hardware insert 520. Therefore, the hardware insert 520 can be combined with the injection molded part 510 product by insert injection molding, and the hardware insert 520 is fixed in the injection molded product to prevent the hardware insert 520 from shifting.
[0044] like Figures 1-7 As shown, based on the above embodiment, the first insert pin 300 is further provided with a first limiting part 320, which is used to contact the hardware insert 520 so that the first insert pin 300 limits the hardware insert 520.
[0045] In this embodiment, the first limiting part 320 can contact the metal insert 520 to limit the first insert pin 300 to the metal insert 520.

[0047] In this embodiment, the first insert pin 300 can be inserted into the first mounting hole 110 and the fixing part 310 and the first limiting part 320 can extend out of the first mounting hole 110. Therefore, the first insert pin 300 can be inserted into the first mounting hole 110 before processing and removed from the first mounting hole 110 during demolding, thereby improving the convenience of the injection mold of the hardware insert 520.
[0048] like Figures 1-7As shown, based on the above embodiment, the first mold core 100 is further provided with a first contact groove 120, the first contact groove 120 is connected to the first mounting hole 110, and the first insert pin 300 is further provided with a first contact portion 330, the first contact portion 330 can contact the bottom of the first contact groove 120 to limit the maximum distance that the fixing portion 310 and the first limiting portion 320 extend out of the first mounting hole 110.
[0049] In this embodiment, the first contact portion 330 can contact the bottom of the first contact groove 120 to limit the maximum distance that the fixing portion 310 and the first limiting portion 320 extend out of the first mounting hole 110, and prevent the first insert pin 300 from falling out from the end opposite to the mounting end.
