Injection molding machine having an injection molding unit with multipleworking positions

Abstract From the Canadian patent

An injection molding machine includes a mold closing unit which is adapted to selectively accommodate injection mold assemblies having injection openings with different axes. Accordingly, the injection molding unit of the injection molding machine is capable of selectively assuming a plurality of working positions. Each working position is associated with an injection axis. A first working position is assumed in case the mold assembly held by the mold closing unit has a central injection opening, in which case the injection in that working position occurs in a central injection axis. The other working positions are associated with off-center injection axes to be associated with …
