PROBLEM TO BE SOLVED: To provide a synthetic resin foam molding method capable of monolithically molding a region requiring strength/rigidity at the same time in a synthetic resin foamed molded article. SOLUTION: In the synthetic resin foam molding method for injecting a synthetic resin foamable substrate 4 in a mating mold comprising a fixed mold 1 and a movable mold 3 to perform the foam molding thereof, A pressure member 8 capable of being moved into the mold to advance and retreat is provided to the fixed mold 1 at the region requiring strength/rigidity of the foamed molded article and, at the time of foam molding of the synthetic resin foamable substrate 4 injected in the mating mold, the pressure member 8 is moved so as to advance and retreat to partially press the foamed molded article to suppress the foaming of the pressed part. |
