Abstract

PURPOSE: To provide the titled intermediate blank having a uniform wall thickness at its spread portion by a method wherein the inside surface of the bottom wall is made horizontal and the horizontal surface is made larger in diameter than the mark of a gate.
CONSTITUTION: A molten resin material is injected from a gate 31 into a cavity 29 formed by molds 28, 28 and a core 30, to mold an intermediate blank 21. In this case, by setting a horizontal surface 32 at the tip end of the core 30 to be larger in diameter than the gate 31, the injected material is once caused to impinge upon the surface 32 before uniformly diffused toward the periphery of the cavity 29 to fill up the cavity 29. Since the core tip end is not spherical, injection of the molten resin material can be uniformed and generation of nonuniform wall thickness can be prevented.
