<p>An injection unit for an injection moulding machine, in particular for processing thermoplastic materials, has a rotatable screw which is disposed in an axially displaceable material cylinder and which is axially displaceable relative to the cylinder. Both the cylinder and the screw are movable by their own respective hydraulic cylinders. The cylinder is fixedly connected to bar members which are displaceable by hydraulically actuated pistons. Each bar member carries a further piston which is slidable in a cylinder which is connected to the screw or the actuating means thereof.</p> |
