[0026] In the utility model, the movable insert structure used to form the air outlet can move synchronously with the product when the product is ejected. After the product is separated from the lower template, the product can be lifted up at a certain angle to be peeled off from the movable insert structure to prevent product damage. The forced core pulling component 4 can automatically force the core to be pulled when the mold is opened to facilitate product demolding.

[0027] Specifically, the movable insert structure comprises a movable insert 5 with a sawtooth structure at the top, and the bottom of the movable insert 5 is connected to the top plate through a plurality of straight push rods 6. When the product is ejected, the top plate moves upward and can push the movable insert and the product to move synchronously through the straight push rods.

[0028] Preferably, the fixed insert 3 is detachably connected to the lower template 1 via a plurality of screws.

[0029] Specifically, the forced core-pulling assembly 4 includes a core-pulling seat 7, the inner end of which is against the fixed insert 3 away from the side of the movable insert 5, and the forced core-pulling assembly 4 also includes a driving structure capable of driving the core-pulling seat 7 to move in the horizontal direction, the driving structure comprising two core-pulling sliders 8 slidably matched with the lower mold plate 1 and two driving rods 9, the driving rods 9 are tilted and the two driving rods 9 are respectively inserted into the two core-pulling sliders 8. When the mold is opened, the upper mold plate moves upward to drive the driving rod to move vertically upward, the driving rod moves upward to drive the movable slider to move horizontally, and the movable insert moves to drive the core-pulling seat to move to realize core pulling.

[0030] Specifically, the core-pulling slider 8 and the core-pulling seat 7 are integrated.

[0031] Specifically, there is a sliding gap 10 between the side of the core pulling seat 7 away from the fixed insert 3 and the lower mold plate 1. The sliding gap can be used for the core pulling seat to move horizontally.

[0032] Preferably, the lower mold plate 1 is further provided with limiting pressing plates 11 on both sides, and the core-pulling slider 8 is inserted into the bottom of the limiting pressing plates 11. The limiting pressing plates can limit the core-pulling slider.

[0033] The working principle of the utility model is that the movable insert structure used to form the air outlet can move synchronously with the product when the product is ejected, and after the product and the lower template are separated, the product can be lifted up at a certain angle to be peeled off from the movable insert structure to prevent the product from being damaged. The forced core-pulling component 4 can automatically force the core to be pulled when the mold is opened, so as to facilitate the demoulding of the product;
