Specifically, limiting plate 140's setting can be used for blockking the removal stroke of push pedal 131, like this when promoting push pedal 131 forward and the butt on limiting plate 140, can know push pedal 131 this moment and move and target in place, so, the suitable position of whole lower mould subassembly 1's position also portable can carry out operation on next step, easy operation is high-efficient.

In another embodiment of the present invention, as shown in fig. 5 to 6, a handle (not shown) is disposed at the front end of the lower mold plate 10 of the multi-step composite forming mold for food can body. Specifically, the worker can pull out the lower die assembly 1 from below the upper die assembly 2 or push the lower die assembly 1 to below the upper die assembly 2 by holding the handle.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
