Claims

[Scope of Claim for Utility Model Registration] (1) A clamping device for fixing a mold to the board surface of a mold mounting board, which is provided with an elongated block-shaped main body member, which is incorporated into the main body member orthogonally to the board surface, and A plurality of hydraulic cylinders with piston rods protruding toward the board surface are provided, and the screw shaft portion at the tip of the piston rod is fixed to a screw hole in the board surface to hold the main body member at a predetermined position outside the board surface, and between the main body member and the board surface. A clamp member is provided that extends along the main body member and extends toward the mold side from the main body member, and a fulcrum part that contacts the board surface is formed at one end of the clamp member on the side opposite to the mold, and the other end A point of action for pressing the mold is formed in the clamp member, and a plurality of elongated slits are formed in the clamp member, through which piston rods of a hydraulic cylinder are respectively inserted, and which face from the one end to the other end. clamping device. (2) A clamping device for fixing a mold to the surface of a mold mounting board, which has an elongated block-shaped main body member removably fixed to the board surface, and a piston rod that is installed in the main body member orthogonally to the board surface. A locking member is fixed to the tip of the piston rod, and a locking member is provided between the main body member and the locking member, and extends along the main body member and is closer to the mold than the main body member. A clamp member is provided that extends to the clamp member, and one end of the clamp member on the side opposite to the mold forms a fulcrum part that comes into contact with the board surface, and the other end forms an action point part that presses the mold, and the clamp member A clamp device characterized in that the member is formed with a plurality of elongated slits through which piston rods of a hydraulic cylinder are respectively inserted and which are directed from the one end to the other end.
