A mould closing unit (100) for an injection-moulding machine has an electromechanical closing mechanism (M) for opening and closing an injection mould, said electromechanical closing mechanism (M) being actuated by means of at least one spindle unit (10) having at least one spindle (12) and at least one spindle nut (14). Cooling by way of cooling ducts (32) for heat dissipation from the spindle unit (10) is provided. Since the spindle (12) has, in the core, at least one bore (24) in which a cooling and/or lubricating medium is passed into the region of the contact points between the spindle nut (14) and the spindle (12) via at least one lance (20), efficient cooling of the spindle unit is achieved.
