Title: INJECTION MOLDING DIE, RESIN MEMBER, AND METHOD FOR PRODUCING RESIN ARTICLE
Abstract:
An injection molding die equipped with a gate and a cavity, and configured in a manner such that a weld section is formed inside the cavity by injecting a reinforcing fiber-containing molten resin into the cavity through the gate, wherein the cavity surface of the injection molding die has a plurality of ridge sections 140 which are located on the downstream side of the cavity in the direction in which the resin flows, and project into the cavity and extend in a direction that intersects the direction in which the weld of the weld section extends. The plurality of ridge sections are separated from one another in the direction which intersects the direction in which the weld extends, and are also separated from one another in the direction in which the weld extends.
