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).
