摘要： An apparatus to actuate an injection element (1) for injecting a defined quantity of plasticized plastic or the like into an injection molding tool. The injection element (1) is designed as a piston or as a screw and is guided in a guide (2) and moved by an actuation element. The actuation element (3) has a tappet (4), which is guided on a crank plate (5), the crank plate (5) being turned with positional accuracy by a controlled or regulated servomotor (6). The invention provides that, for the return stroke of the injection element (1), a second tappet (7) is present, which is actuated by a second crank plate (8).
