Abstract

An injection-molding machine with a set of stacked mold plates, defining several axially spaced mold cavities therebetween, includes an injection unit with one or more nozzles movable perpendicularly to the stack for contact with respective inlets, leading to the several cavities, which are aligned with these nozzles in the closed position of the multiple mold. The mold plates may be interconnected by a lazytong linkage or by lost-motion couplings for proper relative spacing in the open mold position.
