Specifically, the push plate 91 is slidably matched with the two slide rails 92, so that the sliding of the lower die plate 10 can be ensured to be always guided by the two slide rails 92, the moving route is constant, and the operation efficiency is improved.
In another embodiment of the present invention, as shown in fig. 1 to 5, a limiting plate (not shown) for limiting the sliding travel of the push plate 91 is disposed on the bottom plate 80 of the food can body rolling and beading mold near the rear end. Specifically, the setting of limiting plate can be used for blockking the removal stroke of push pedal 91, when pushing forward and the butt on the limiting plate with push pedal 91 like this, can know that push pedal 91 at this moment removes in place, so, the position of whole lower die assembly 100 also portable suitable position can carry out the operation of next step, easy operation is high-efficient.
In another embodiment of the present invention, as shown in fig. 1 to 5, a handle (not shown) is provided at the front end of the lower die plate 10 of the food can body rounding and beading mold. Specifically, a worker may facilitate pulling the lower die assembly 100 from below the upper die assembly 200 or pushing the lower die assembly 100 to below the upper die assembly 200 by holding the handle.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
