レス型。 A block equipped with an upper die curved blade for pre-bending the edge of a workpiece set on the lower die body is movable up and down with a predetermined stroke in the upper die body, and is urged to the lowering end position by a pressing member. The lower mold body is provided with a lower mold bending blade for bending the pre-bent edge of the workpiece to a negative angle, and a cam block that is movable forward and backward toward the edge of the workpiece on the lower mold body is installed; A passive cam surface is formed at the rear end of the cam block, and a driver cam that contacts the passive cam surface and moves the cam block forward is fixed to the upper mold body, and the lower surface of the block and/or the upper surface of the cam block are fixed. 1. A press mold characterized in that a cam is provided on the surface of the cam block to raise the block to a position where the upper mold curved blade does not interfere with the lower mold curved blade by the forward movement of the cam block.
