发明名称 MOLDING METHOD FOR PLASTIC FOAM USING SPRAYING
摘要 The present invention relates to a method for producing a synthetic resin foam molded product (10) such as a vehicle seat buffering body or the like. A liquid synthetic resin raw ingredient is sprayed to an upper mold (11) of a coupling-type mold having an upper mold (11) and a lower mold (12) assembled therein, so an adhesive layer (15) having a synthetic resin raw ingredient is formed on an inner surface of the upper mold (11). The adhesive layer (15) is downwardly foamed and expanded, so the molded product (10) is produced. According to the present invention, defection such as bubbles or dent parts which may occur on a surface of the molded product (10) due to defection in foaming may be fundamentally prevented. Also, distribution of tissue and pores in the completed molded product (10) may be uniformized, so quality of the synthetic resin foam molded product (10) may be remarkably improved.
