Abstract
Disclosed herein is a production apparatus of expansion-molded articles, comprising a mold equipped with a foamed particle feeder having a foamed-particle feed opening and a compressed-air ejection nozzle opening toward the mold, by which foamed particles contained in a hopper is filled into the mold through the foamed-particle feed opening by ejecting compressed air from the compressed-air ejection nozzle and then heated to expand them, and the foamed particles thus expanded are then cooled, thereby producing an expansion-molded article, wherein the apparatus is equipped with a compressed-air discharge orifice opening toward the foamed particle filling side of the apparatus in the course of a foamed-particle supply line connecting the hopper to the foamed-particle feed opening. An auxiliary member for transfer of foamed particles used in the production apparatus, and a production method of expansion-molded articles using this apparatus are also disclosed.
