Claims

[Scope of utility model registration request]

A block equipped with an upper mold curved blade that primarily bends the edge of the workpiece set on the lower mold body is installed in the upper mold body so that it can move up and down with a predetermined stroke and is biased to the lowering end position by a spring. a lower die body is provided with a lower die curved blade for secondarily bending the edge of the workpiece that has been bent primarily at a negative angle; a cam block that is movable forward and backward toward the edge of the workpiece on the lower die body is installed; A passive cam surface is formed on the upper mold body, a driver cam that contacts the passive cam surface and moves the cam block forward is fixed to the upper mold body, and a protrusion is provided on the lower mold body to allow movement of the cam block. A press mold characterized in that the block of the upper mold main body is provided with a distance block that comes into contact with the protrusion and defines a position at which the primary bending of the upper mold curved blade is completed.
