  • Injection means for an injection moulding machine
    Patent number: 6494701
    Abstract: An injection moulding machine with a screw (3) for metering plastics, which is mounted in a rotatable manner in a clamping plate (8), which is longitudinally displaceable by way of at least two electrically driven spindles (5), whereby the pressure exerted by the plastics upon the screw (3) is determined by means of at least one sensor (14; 15) which measures the deformation of a connecting ring arranged between a stationary sleeve (9) surrounding the pivot bearing (16) of the screw (3) and the clamping plate (8); the connecting ring is configured as an annular disc (10), the inner edge (11) of which is connected to the sleeve (9) and the outer edge (12) of which is connected to the clamping plate (8).

  • Injection unit for an injection moulding machine
    Patent number: 6241504
    Abstract: Injection unit for an injection moulding machine, with a housing (1) carrying a plasticising cylinder (2) and with a transverse support (8) arranged movably in the housing (1), which support is connected to a plasticising screw (9) mounted in a rotatable and longitudinally displaceable manner in the plasticising cylinder (2), wherein piston rods (6) projecting on both sides in the longitudinal direction of the injection unit are connected to the transverse member (8), the free ends of which (6a, 6b) each enter into a cylinder chamber (7a, 7b) in the manner of plungers.
