Claims

[Scope of Claim for Utility Model Registration] A clamping device for fixing a target article, such as a mold, to a stationary platen to which the target article is attached, which includes a hydraulic cylinder provided in the clamp body perpendicular to the platen surface, and a piston rod of the hydraulic cylinder. The piston of the hydraulic cylinder and the piston rod are formed so that they can be fixed to the panel surface by protruding an appropriate length from the clamp body toward the panel surface, and screwing the mounting screw part at the tip of the piston rod on the panel surface side into the screw hole on the panel surface. An operating rod is provided protruding from the side opposite to the piston rod, and the operating rod is slidably fitted into the rod hole of the clamp body so that its outer end is exposed to the outside, and the piston and piston rod are attached to the outer end of the operating rod. An operating part for rotational operation is formed, a clamp oil chamber is formed in the hydraulic cylinder to drive the clamp body toward the panel side relative to the piston, and the end of the clamp body on the panel side is provided with an object. A clamp device characterized by forming an action point for pressing an article.
