发明名称 STAMPING MOLDING OF THERMOPLASTIC RESIN SHEET
摘要 PURPOSE:To permit to prevent generation of thin parts in the molded product of resin by a method wherein adhesive sheets are adhered to the parts where large elongations are readily generated upon molding the resin sheet by stamping. CONSTITUTION:The cut resin sheet 2 is conveyed to a stamping molding machine 6 under a condition that the temperature thereof is kept so as not to reduce the plastic property thereof, however, the adhesive sheets 5 are adhered in this case to the predetermined positions of a surface which becomes the rear surface of the product after molding the resin sheet 2. The predetermined positions are the parts of the resin sheet 2, whereat elongations larger than the other parts are readily generated upon molding the resin sheet 2 by stamping. The adhesive sheets 5 are adhered to these parts and the elongations of these parts are restrained, therefore, generation of thin parts of the resin molded product 17 at the stepped sections 17 may be prevented by the elongations of the parts around the adhered adhesive sheets and the plastic flow of the resin material at these parts.
