摘要

PROBLEM TO BE SOLVED: To provide an injection molded article of plastics, which can be piled, the plastics having bottom walls, peripheral edges and side walls spreading toward the spaces between the bottom walls and peripheral edges, and also to provide a die and a method for the molding.;SOLUTION: A fluidizable plastic material injected in a cavity in an injection molding die for a plastic molded article (10) is oriented to a direction of a side wall area among a plurality of main fluidizing guides. The side wall area contains a narrow die cavity area for molding a thin side wall part (20) and a sub fluidizing guide for orienting the injected fluidizable plastic material to the narrow die cavity. The side wall (16) of the molded article contains a plurality of step parts (24) for separating at least some thin wall parts from one another and also a plurality of step parts for separating the narrow die cavity parts.;COPYRIGHT: (C)2006,JPO&NCIPI
