Abstract

An apparatus for the production of die-cast parts is described, wherein the melt is pressured under a low pressure into a die where it solidifies. A casting unit has a drive piston guided in a casting cylinder and connected to a casting piston. The casting piston is equipped with terminal stops in both directions. The casting piston, which has a large cross-section, is able to travel into a movable half of the die. The casting cylinder is displaceably supported on a guide in the direction of the axis of the drive piston, with the terminal stops being adjustable relative to the drive piston and relative to each other. A signal transducer is associated with the stroke path of the drive piston and detects the end position of the casting piston within the moving half of the die. Thus, in a so-called pressure mold casting process, different casting strokes may be effected with the same machine, and both the end of the stroke of the casting piston and the onset of the casting stroke may be adapted to different dies by an adjustment of the entire casting unit.
