After the stamping is completed, the upper module 1 moves up, the mounting frame 51 moves up and drives the second moving block 59 to move up. When the second moving block 59 moves up and contacts the moving plate 510, the moving plate 510 is driven to move up, so that the connecting rod 53 moves up, and then drives the four groups of positioning plates 31 to move away from the aluminum plate, so as to facilitate taking out the formed aluminum plate when the upper module 1 moves to the high position.
