  • Apparatus for the production of die-cast parts with adjustable piston travel length and initial and final positions
    Patent number: 4530391
    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.
