Abstract:
1. Mold clamping unit for injection molds on an injection molding machine for processing plastics and other plasticizable compounds such as ceramic or powdery compounds, comprising a first mold carrier, a movable mold carrier that can move relative to the first mold carrier which together with the first mold carrier creates a mold clamping space to receive an injection mold between the movable mold carrier and the first mold carrier, a support element for an electromechanical clamping mechanism for the cyclical opening and closing of the injection mold as the movable mold carrier moves towards and away from the first mold carrier, wherein the clamping mechanism has a servo motor as drive motor, which has at least one spindle drive with a spindle interacting with a spindle nut at a bearing position for a relative motion between the spindle and the spindle nut, said spindle being operatively coupled with the movable mold carrier so as to move it, a liquid cooling with cooling channels for dissipating heat from the clamping mechanism, wherein the cooling channels penetrate at least one of the bearing position, wherein the spindle and the spindle nut operate together during the relative motion, of the spindle drive or a cooling plate, said cooling plate disposed adjacent to the bearing position.
