Claims

[Scope of utility model registration request]

It has a lower mold on a fixed side and an upper mold on a movable side that moves up and down with respect to the mold, and the lower mold has a circular die center and a circular die center that fits into the die center and is supported so as to be able to descend. The upper mold includes a pressing ring and an annular die cutter provided on the outside of the pressing ring, and the upper mold includes a stripper that comes into contact with the die cutter to clamp the material plate at the initial stage of descent, and a stripper that clamps the material plate by the stripper. A circular punch center that is then pressed into contact with the die center of the lower mold;
An annular punch cutter that presses against the pressing ring and presses it down after the punch center is pressed, and an annular draw ring that descends to the outside of the die center together with the punch cutter, and a draw ring that descends below the lower mold. A trimming cutter is provided that contacts the drawling to stop the drawling, and the trimming cutter has a cutter edge that is concentric with the die center and projects from the die center by a width of the mouth edge determined for the product container. The mold apparatus for manufacturing cylindrical containers is constructed such that the punch cutter passes through and descends while rubbing against the edge of the trimming cutter after the drawing stops.
