PROBLEM TO BE SOLVED: To provide the molding method for a foam molding, irregularity in density of which is suppressed. SOLUTION: This molding method of a foam molding is to mold the foam molding having a predetermined shape from a thermoplastic synthetic resin and equipped with a plasticizing process for thermally plasticizing the synthetic resin under the condition that a foaming agent is mixed with the synthetic resin, a feeding process for feeding the plasticized synthetic resin together with the foaming agent through a feed passage 6 to an injection chamber 300, a clogging process for clogging the feed passage 6 after the resin is fed to the chamber, and an injecting process for injecting the synthetic resin from the injection chamber 300 to a mold 4 after the clogging of the feed passage. |
