備してなることを特徴とするプレス型。 A press mold that uses a bead formed to fix a workpiece as part of the product shape and has a bent flange part outside the bead, and includes a punch and a punch. a lower mold having a blank holder which is movable up and down on the outside of the mold and which is normally biased so that its upper surface protrudes beyond the mold surface of the punch; After forming a bead on the outer side of the workpiece in cooperation with the blank holder, the die forms the main forming part of the workpiece in cooperation with the punch, and the die can be moved up and down. The mold surface is usually located recessed from the mold surface of the die, and as the die approaches the blank holder and punch, it approaches the blank holder separately from the die, and the die approaches the blank holder separately from the blank holder. an upper die having a flange forming blade that cooperates with a blank holder to form a bending flange portion on a portion of the workpiece outside the mold from the bead after forming the bead on the workpiece in cooperation with the workpiece; A press mold that is characterized by
