Abstract
Molding apparatus for molding articles without a seam or parting line even though the articles may have severe backdraft portions. The apparatus includes a flexible mold of relatively thick and self-supporting wall construction which is deformable by the application of fluid pressure differential to thereby release the finished article from the mold. One modification of the mold also has a thick radially extending flange which forms a seal with a vacuum pot when the mold is simply set in the pot. One modification is directed to a male and female type mold in which the outer female mold is expanded to be withdrawn from the article and the inner mold portion collapses inwardly so as to be withdrawn from the article. Another modification relates to a mold having inner portions which define an aperture or opening in the article to be molded, and which inner portions are separable from one another when the mold is expanded to thereby withdraw the inner portions from the aperture in the article and permit withdrawal of the mold.
