Method for manufacturing foam molded body

A method for manufacturing a foam molded body, comprising the steps of:

• an arranging step to arrange one sheet of a foam resin sheet between a first mold and a second mold, the foam resin sheet being formed by extruding and dangling a molten foam resin from a slit;
• and
• an expanding step to expand the foam resin sheet by subjecting the foam resin sheet to a reduced pressure suction in a condition where the first mold and the second mold are closened to provide a gap between the first mold and the second mold, the gap having a thickness larger than a thickness of the foam resin sheet, thereby expanding the foam resin sheet to have the thickness of the gap,
• wherein a temperature of the foam resin sheet increases toward a center of the foam resin sheet in a thickness direction of the foam resin sheet in a state before the foam resin sheet comes in contact with any of the first and second molds
• wherein the expanding step comprises performing a first suction step, a mold closening step, and a second suction step in this order;
• the first suction step comprises subjecting the foam resin sheet to reduced pressure suction by the first mold, thereby shaping the foam resin sheet to follow a shape of a cavity of the first mold;
• the mold closening step comprises closening the first mold and the second mold to each other to provide the gap in between the first mold and the second mold;
• the second suction step comprises subjecting the foam resin sheet to reduced pressure suction by the first mold and the second mold, thereby expanding the foam resin sheet to have the thickness of the gap.
