摘要
The invention relates to an injection screw drive for a plastic injection molding machine comprising axes (A1, A2) respectively provided for the rotative and for the axial motion of the injection screw (4). According to the invention, the injection screw drive has at least one double rack rail overdrive for effecting the axial motion. The injection worm drive is configured as a gear combination having at least two drive motors (18, 44) and an output axle. The gear combination has, as a core, a gear block with a gear casing (42), to which at least two reducing gears are connected that effect the rotative and the axial motion of the injection screw (4). This enables the entire machine to be provided with a short and compact structure insofar as this concerns the injection aggregate. According to a second embodiment, both drives have separate housings. The entire injection unit rests, in a known manner, on the machine stand (33) via guide rails (32) such that it can be displaced.
