Abstract:
Injection means for 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 means of at least two electrically driven spindles (5), wherein the pressure exerted by plastics upon the screw (3) is determined by at least one sensor (14; 15) which measures the deformation of a connecting ring arranged between a stationary sleeve (9) surrounding the bearing of the screw (3) and the clamping plate (8), characterised in that 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).
