Abstract
A casting machine having a mold closing and opening cylinder for moving a movable die plate with a movable die relative to a stationary die plate having a stationary die, and a mold clamping cylinder each having a cylinder housing and a piston which partially define a first and a second fluid chamber whose volumes increase when the movable die plate is moved toward and away from the stationary die plate, respectively, by the mold closing cylinder. The clamping cylinder is connected to a hydraulic circuit, which permits a fluid to flow between the first and second chambers through a connecting line when the movable and stationary die plates are moved relative to each other by the closing and opening cylinder. The hydraulic circuit is adapted to apply a fluid pressure to the first fluid chamber to clamp the movable and stationary dies together after the movable die is brought into abutting contact with the stationary die by the closing and opening cylinder.
