Two U-shaped rods 6 are fixedly connected to the inner wall of the frame body 1. Both of the two U-shaped rods 6 penetrate through the lifting plate 4 and are slidably connected thereto. The cooperation of the U-shaped rods 6 and the lifting plate 4 can make the lifting of the lifting plate 4 and the moving die 5 stable, and the die-closing effect of the moving die 5 and the fixed die 2 is good.

[0020] There are two demoulding mechanisms on the lifting plate 4. The demoulding mechanism includes a connecting rod 7 fixedly connected to the bottom of the lifting plate 4. The bottom of the connecting rod 7 is fixedly connected to a sealing block 8. The inner bottom of the frame body 1 is fixedly connected to a hollow column 9. An air vent hole 19 is penetrated and opened on the hollow column 9. The sealing block 8 is located inside the hollow column 9 and is in sealed sliding connection therewith. The connecting rod 7 penetrates through the hollow column 9 and is in sealed sliding connection therewith. When the sealing block 8 moves downward, the outside air is injected into the hollow column 9 through the first connecting pipe 10. When the sealing block 8 moves upward, the air in the hollow column 9 is injected into the cavity 13 through the second connecting pipe 12, and the product is jacked up to facilitate the removal of the product.

[0021] The side wall of the hollow column 9 is provided with a first connecting pipe 10 communicated therewith. The outer wall of the first connecting pipe 10 is fixedly connected to a fixed one-way valve 11, which can allow the outside air to be injected into the hollow column 9 through the first connecting pipe 10.
