ABSTRACT:
A slidably attachable, automated means for opening and closing the die halves of a casting machine. Cylinders are provided having integral vertical side grooves for mounting on said casting machines and the like. The preferred hydraulic cylinder has a hollow piston rod connected to the piston and projecting from one end of the cylinder. A fluid flow line movable within the cylinder projects from the other end of the cylinder and slidably passes through the piston into the piston rod. Separate elements contact the piston at opposite ends of its stroke to move the fluid flow line and switch the fluid flow in the cylinder.
