A closing unit for an injection moulding machine has a movable closing die and a fixed matching die designed as clamping dies for an injection mould, as well as several hydraulic cylinders mounted on the fixed matching die to apply a closing force. A servo-drive allows the drawbars to swivel around their longitudinal axes up to a first and second angular position. A first locking device arranged on the drawbars along a first section A of the drawbars co-operates with second locking device arranged on the movable closing die. In the first angular position of the drawbars, the locking devices allow the movable closing die to move axially with respect to the drawbars, and in a second angular position of the drawbars they transmit the required closing force.
