In an injection moulding unit for an injection moulding machine, an injection motor (E) is provided for actuating an electromechanical injection unit (16) for axially moving the conveyor means (12). An electromechanical rotation motor is provided to rotate the conveyor means independently of the axial movement. Rotation motor (R) and injection motor (E) move the conveyor means via a first driving element (19) and a driving element (20) coaxially arranged to the first driving element (19). An axial bearing element (21) is arranged directly between the first (19) and the other driving element to axially move the conveyor means (12) via linear displacement means (16a) of the injection unit (16). The axial bearing element is thus a force-transmitting element, but also serves as a parting means to allow the driving elements (19, 20) to be independently and if necessary simultaneously rotated. The metering and injecting driving elements can thus be coupled in a simple and compact manner to an injection moulding unit.
