Abstract

PURPOSE:The titled die for press forming of sheet metals which is produced at low cost and capable of obtaining high-quality products comparable with those obtained by use of metal dies, comprising forming surfaces which are formed by covering with metal plates of specified thickness the opposite surfaces of upper and lower main bodies made of plastic mixed therein with metal powder. CONSTITUTION:The metal plates 7, 8 are adhered to the opposite surfaces of the upper die 3 and the lower die 5 both made of plastic mixed therein with metal powder, to form the molding surfaces. The thickness of the metal plates 7, 8 at the molding surfaces is 0.5-1.2mm.. When the dies are used in press forming of the sheet metal 9, products of high quality are obtained without sag, deformation, peel of longitudinal walls, generation of steps, etc. The main bodies 3, 5 can be manufactured at low cost because they are made of plastic.
