Abstract

An injection unit for an injection molding machine has a plasticising cylinder and a plasticising screw arranged axially displaceably therein. The plasticising cylinder is fixedly connected to a housing which, at two mutually opposite walls, carries a respective crank drive extending parallel to the wall for displacement of the plasticising screw. A motor for driving the crank drive is internally fixed to the wall and the axis of rotation of the motor extends normal to the crank drive.
