Claims

[Scope of utility model registration request]

゛ An upper die that presses a workpiece in cooperation with the lower die is installed in a vertically movable manner above the lower die, and the workpiece is raised to a lower operating rod that is attached to the lower die in a vertically movable manner. At the same time, a lifter is attached, and a lower elastic body is attached to the lower die to apply a resilient force toward the upper die to the lower actuating rod, and an upper actuating rod that comes into contact with the lower actuating rod is attached to the upper die. An upper elastic body is attached to the upper mold so as to be movable up and down and gives an elastic force toward the lower mold to the upper operating rod, and a spring between the upper elastic body and the lower elastic body is attached to the upper mold. A mold release device for a workpiece in a press mold, characterized by having a difference in constant.
