ABSTRACT:
A resin-molding mold device is provided for carrying out the resin molding process to mold the resin molded article, wherein when cooling after charging a molten synthetic resin into a cavity (14) and maintaining the pressure, a movable core (11) is urged to the side in which the capacity of the cavity (14) is decreased. This enables a resin molded article having a proper shape to be reliably molded by preventing a design surface from parting from a cavity wall surface when die-molding the resin molded article by charging a molten synthetic resin into a cavity formed from a plurality of dies.
