Abstract

PURPOSE: To prepare a multi-layered molded article using a single mold, easily and rapidly, by injecting the first resin in a cavity of the mold, and after solidifying the surface layer of the injected resin, enlarging the cavity and injecting the second resin into the newly produced space.
CONSTITUTION: The first resin in the first injection cylinder 1 is injected into a cavity of a mold through an outer nozzle 5 and a gate 9, and after at least the surface layer of the resin contacting with the wall of the mold is solidified, the movable half 8 is retreated and the cavity is enlarged corresponding to thickness of the spacer 10. The second resin accumulated in the second injection cylinder 2 is injected into the cavity newly formed along the gate-side wall of the mold, and the objective double-layered molded article 11 is obtained. It is necessary that the nozzle 5 interconnects to the mold cavity newly formed by the retreat of the movable half 8.
