Claims

[Scope of utility model registration request]

In a press forming device that performs drawing forming while applying tension to a press work, a lower die punch is supported on the lower die body via an elastic member so as to be movable up and down, and the lower die punch is moved up and down in opposition to the lower die punch. The lower die blank holder is movable vertically and laterally on a cushion member that is always urged upward on the lower die body on the side of the lower die punch, and is urged toward the center. At the same time, an upper die blank holder, which faces the lower die blank holder, is supported at the side part of the upper die so as to be movable in the lateral direction and biased towards the center, A cam is provided to move the lower blank holder away from the lower punch in one direction when the lower blank holder is lowered,
Further, the upper die is supported by the upper die via an elastic member so as to be movable up and down, and after the cam finishes the lateral movement of the lower die blank holder, the cam engages with the lower die blank holder to prevent lateral movement, and the lower die blank holder 1. A press-molding apparatus characterized in that a retaining member is provided that releases engagement when the upper die further rises after reaching the raised position.
