Abstract

Apparatus for producing foamed articles of thermoplastic synthetic resin, characterized in that it comprises metal molds, each consisting of an upper mold and a lower mold; a transportation path for said metal molds; direction change devices for metal molds, provided on said transport path; means for removing or separating the upper mold from the lower mold; means for driving said upper mold, which has been removed, to another transport path, which is separated from said transport path of said lower mold; a mold releasing device for extracting the molded article from the lower mold, the upper mold having been removed; means for filling a foaming resin material in the lower mold, from which the molded article has been removed; means for closing the metal mold by stapling the upper mold on the lower mold, which has been filled with resin material; a heating device, which has at least three degrees of temperature regions; that is, to preheat the metal mold, heat the resin and finish the resin mold; and means for cooling the metal mold containing the molded article.
