Abstract

An injection moulding machine comprises a mould closure unit 9 and an injection moulding unit 14 which includes a plasticizing device 5 with a plasticizing screw 13. A drive arrangement is provided which includes a variable-speed electric motor 1, open and closed loop control devices for controlling the speed of the motor 1, and one or two hydraulic pumps 2 acting as pressure flow generators for operating pressure flow loads of the mould closure unit 9 and of the injection moulding unit 14. The drive arrangement also includes force-transmitting machine elements, i.e. a clutch 3 and a transmission gearing 4, for transmitting a torque. During operation of the machine, the motor 1 rotates the plasticizing screw 13 either via the clutch 3 or via the clutch 3 and the transmission gearing 4, and simultaneously drives the two pumps 2. After the plasticizing stage the drive from the motor 1 may be parted from the screw 13 via the clutch 3 and used wholly for the injection stage, e.g. for damping the moulds. <IMAGE>
