Abstract:
1. A resin molding process for die-molding a resin molded article by charging a molten synthetic resin into a cavity formed from a plurality of dies, comprising the steps of: providing a first die having a design surface facing the cavity; providing a movable core having a molding surface forming at least part of a non-design surface on the side opposite the design surface of the molded resin article, wherein the movable core moves relative to a movable core support and wherein the movable core is biased toward the first die; moving the movable core support and the movable core to a position toward the first die; charging the molten synthetic resin into the cavity, wherein the molten resin moves the movable core in a direction opposite the first die; moving the movable core support in a direction opposite the first die, while continuing to bias the movable core toward the side on which the capacity of the cavity is decreased, when cooling after charging the molten synthetic resin into the cavity.
