Since the movable die dismounting block is mounted to the fixed die seat through the clamping blocks, the mounting strength of the movable die dismounting block and the movable die seat can be improved, and the structure is more reasonable.

[0017] Optionally, a guide slope is formed in the clamping block, and the guide slope is used to guide the clamping block to move away from the clamping groove when the movable die dismounting block is mounted into the second mounting groove.
