Abstract
A drive unit, in particular for a closing unit, an injection unit, or an ejector of an injection molding machine, may be used where a high axial force is applied through a hydraulic power converter. A cylinder of the power converter may be fixed relative to a frame of the injection molding machine through the intermediary of a holding device which is functionally separate from guidance of the cylinder on the frame of the injection molding machine.
