The groove 14 is used to guide and position the punching die 1 until the punch assembly is docked with the punching drive mechanism 3. The two sets of quick locking mechanisms 7 lock the two supporting shoulders 15 of the fixed plate 13 of the upper die assembly 11, and the mold front end clamping mechanism 8 clamps the front side of the fixed plate 13 of the upper die assembly 11 to achieve the installation of the punching die 1; at this time, the upper top of the upper driving mechanism 4 is pushed up until the bottom surface of the concave die plate 12 contacts the upper top of the upper driving mechanism 4, and then the locking mechanism is released.

The aluminum-plastic film unloading manipulator 27 is used to place the aluminum-plastic film on the concave mold plate 12 after the mold is opened, and the punching mold 1 is closed to punch and shape the aluminum-plastic film to form an aluminum-plastic film shell. After the punching mold 1 is opened, the aluminum-plastic film picking manipulator 28 takes away the aluminum-plastic film shell to realize automatic unloading and picking.
