Abstract:
1. A foam molding method using a mold for foam molding including an upper mold portion having no recess formed on a lower surface of the upper mold portion, and a lower mold portion defining a cavity, wherein a portion of a vertical side wall of the cavity is recessed to form a recess portion formed on an upper surface of the lower mold portion, and a gas feeder in a bottom surface of the cavity of the lower mold portion, wherein a protruding portion which fits into the recess portion extends directly from the lower surface of the upper mold portion, the method comprising: supplying a raw material into the cavity of the lower mold portion; inserting the protruding portion into the recess portion after the raw material is supplied into the cavity; producing foam after clamping the upper mold portion of the mold to the lower mold portion of the mold; separating the upper mold portion from the lower mold portion to open the mold; after separating the upper mold portion to open the mold, feeding gas to a space between a molded product and a bottom surface of the lower mold portion from the gas feeder to release the molded product from the lower mold portion, wherein the separating the upper mold portion from the lower mold portion extracts the protruding portion from the recess portion thereby exposing an empty space; and inserting a finger or a tool into the empty space to remove the molded product from the mold.
