Synthetic resin multimaterial quality injection molding method and its laminated molding product

Abstract

Abstract PURPOSE:To surely and firmly stick together the primary-and-secondary products by a method wherein in the synthetic resin multimaterial quality injection molding a primary molding product is arranged with projections of fixed length and at the time of secondary molding said projections are buckled and bent. CONSTITUTION:In the synthetic resin multimaterial injection molding the primary molding use resin is injected using a travelling metallic mold 1 and a primary molding use metallic mold 5 to mold a primary molded product A arranged with projections C. Thereby the projection length is preset so as to enable the projections to be buckled or bent by a mold clamp of the secondary molding metallic mold 7. Next the travelling metallic mold 1 holding the primary molded product A arranged with the projections C is turned by 180 deg. to face the secondary molding metallic mold 7 and clamped, the secondary molding resin is injected into the cavity 9 for secondary molding, the secondary molding product B is molded in such a state that the projections C are buckled or bent to be ruried for binding the primary molded product A and the secondary molded product B each other.
