装置。[Scope of Claim for Utility Model Registration] (1) A hydraulic cylinder is provided with a downwardly extending piston rod, and a clamp rod for clamping a die holder equipped with a mold to the hydraulic cylinder side is attached to the piston rod in a bendable manner. In the die clamping device for a press, in which the clamp rod bends outward as the piston rod descends to unclamp the die holder, the hydraulic cylinder is configured such that the piston rod extends upward and downward from the hydraulic cylinder, and A die for press is constructed in a double rod type so that hydraulic pressure is supplied to both sides, and a number of disc springs are superimposed and fitted to the upper piston rod, and the die holder is tightened by the elasticity of the disc springs and the hydraulic pressure. clamping device. (2) A piston rod extending downward is provided in the hydraulic cylinder, and a clamp rod for tightening a die holder equipped with a mold toward the hydraulic cylinder side is connected to the piston rod in a bendable manner, and the clamp rod is moved when the piston rod is lowered. In a die clamp device for a press that bends outward to unclamp the die holder, the piston rod and the clamp rod are connected to each other so as to be bendable by a pin integrated with the clamp rod,
A die clamp device for a press, in which an eccentric protrusion protruding from the shaft end of the pin abuts and is locked to a guide plate fixed to a hydraulic cylinder holding member.
