Abstract

Provided are a method for molding a foamed resin molded article having a mounting hole which is formed with good dimensional precision without occurrence of shape sag and which has an improved load resistance, a mold therefor, and a foamed resin molded article thereby. A method for molding a foamed resin molded articleincluding a mounting sectionand a non-mounting section, using a moldincluding a first moldhaving a non-mounting-section mold portionand a mounting-section mold portion, a second mold, and a cavityhaving a non-mounting-section cavity portionfor molding the non-mounting sectionand a mounting-section cavity portionfor molding the mounting section. The method includes: a filling step of filling a material to be molded into at least the mounting-section cavity portion; and a core-back step of moving at least one of the non-mounting-section mold portion, the mounting-section mold portion, and the second moldso that a cavity width of the non-mounting-section cavity portionis increased while a cavity width of the mounting-section cavity portionis constant, the filling step and the core-back step being sequentially performed.
