An upper mold assembly 2 is provided on the inner side of the mounting frame 1. The upper mold assembly 2 is fixedly connected to the U-shaped sliding block 8. A screw sleeve 9 is embedded in the U-shaped sliding block 8, and a handle 6 is threadedly connected to the screw sleeve 9. A guide rod 7, which is fixedly connected to the bottom of the mounting frame 1, passes through the U-shaped sliding block 8. A lower mold assembly 3 is provided below the upper mold assembly 2 to cooperate with it. By rotating the handle 6, the U-shaped sliding block 8 drives the upper mold assembly 2 to move in the vertical direction.

[0022] Specifically, this utility model allows the U-shaped sliding block 8 to slide vertically under the guidance of the guide rod 7 by rotating the handle 6, thereby driving the upper mold assembly 2 to adjust its position and adapt to packaging bags of different thicknesses. Compared with traditional equipment adjustment methods, it has the advantages of simple and fast adjustment, and shortens the equipment downtime, making the hot press cutting equipment more efficient.

[0023] Furthermore, the top of the U-shaped sliding block 8 is connected to the inner wall of the slide groove 13 by multiple springs 14. The four springs 14 provide a contact force between the mounting bracket 1 and the U-shaped sliding block 8, so that the U-shaped sliding block 8 requires a certain amount of force to move. This avoids external vibrations, accidental touches, and other behaviors that could cause the throttle 6 to rotate and thus change the arrangement position of the upper mold assembly 2.
