ABSTRACT:
An injection molding machine for use with at least two melting and injector units includes a fixed die platen, a movable die platen, and fixed spars on which said movable die platen moved. The die platens mount half-mold parts of injection molds while the other half-mold parts are positioned on a prismatic support base which can be rotated around its axis between these half-mold parts and which is movable in the direction of the fixed spars. The movable die platen mounts movable spars along which the prismatic support base is guided in the area between the two die platens. On the rear face of the movable die platen which faces away from the support base is positioned at least one drive for the two movable spars, and the movable die platen includes at least one runner for plasticized material injected therein from a melting and injector unit.
