ABSTRACT:
An outer mold part is positionable over an inner mold part. Lever means are carried on opposite sides of the outer mold part and operable by a lifting force to exert a separating force between the outer and inner mold parts. Lever means are carried by the outer mold parts for locking the molded article to it. The outer mold part and the molded article are lifted upwardly together as an assembly and are removed entirely from the inner mold part. The assembly is then set down, the outer mold part is unlocked from the molded article, the outer mold part is then picked up and removed from the molded article, and then the bottom is poured in and is connected to the molded article.
