  • Spray head having fluid metering screws
    Patent number: 4799624
    Abstract: A spray head includes a nozzle body having a front side, a rear side and internal passages for conducting fluid. The passages include inlet ports arranged in the rear side to which fluids are supplied. A spray nozzle is mounted on the front side. Metering screws are mounted in the nozzle body for controlling the volume of fluids supplied to the nozzle. Those metering screws are exposed for adjustment in the front side of the nozzle body. The spray nozzle may comprise a flexible tube, or may include a ball-shaped mounting portion which is rotatably mounted in a removable nozzle holder. Support screws for mounting the spray head to a support structure are exposed for actuation in the front side of the nozzle body.

  • Hot chamber die casting machine
    Patent number: 4566522
    Abstract: A hot chamber die casting machine for a processing of molten metals. The die casting machine includes a frame having a slanted surface for accommodating a closing unit. The closing unit is operable from a crosshead by way of a toggle lever mechanism and is mounted on guide bars supported at the frame. The closing unit includes two mold mounting tables which are adapted to be pressed together. A scissors-type linkage mechanism is disposed below the closing unit and includes transversely joined levers with a drive arrangement being provided for spreading the linkage mechanism so as to enable an adjustment of the closing unit.

  • 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.
