摘要

An injection-moulding machine (1), in particular a plastics injection-moulding machine, having a mould clamping unit which is connected to a toggle-lever system (6) and the movable platen (4) of which can be driven by a servo motor (15) via a spindle nut (9; 14), permits a play-free, uniform movement of the movable platen without any higher drive power if a one-part drive spindle (8) has two mutually independent thread sections (10, 11) with different pitches. <IMAGE>
