Abstract

PURPOSE: To mold the worked article having undercut only by a primary processing, by molding and hardening the molding material, rotating the plate like inner mold having the inner peripheral shape at high speed in the outer mold having the outer shape of the article to be worked.
CONSTITUTION: After fluid plastics of amount sufficient enough to mold the worked article 1 is poured into the container-like outer mold 2 which has the shape of the outer part 1c of the worked article 1 and is fixed on the base of the molding apparatus, the inner mold 4 having the plate 4a patterned with the generants of the inner peripheral part of the work 1 is put into the outer mold 2, the opening part 2a of the outer mold 2 is covered by the outer lid 3, and the central axis of the individual molds 2A, 3A, 4A are made to coincide with each other. Then, the inner mold 4 is rotated at high speed by the sustaining shaft 4b integrated with the driving part of the molding apparatus and plastics is filled into the space 5 surrounded by the rotating locus face of the shape of the plate 4a and the outer mold 2, molded and hardened.
