Abstract
A molding device is provided that includes outer and inner rubber molds that define a space therebetween for forming a column. Inserted within the inner mold is an elongated rigid member. A multisectional housing surrounds the outer mold and includes a plurality of sections that in a molding mode are secured together by fasteners. Once the column has been molded between the outer and inner molds, the fasteners are released allowing the sections of the housing to be relaxed or removed from around the outer mold. This permits the outer mold to expand or move slightly outwardly and in response to that outward movement, the pressure or force on the molded column lying between the outer and inner molds is reduced. This facilitates the extraction of the column from between the outer and inner molds.
