ABSTRACT:
An apparatus for de-molding sanitary ware castings from porous molds, and in particular, from synthetic resin molds, comprising a carriage capable of traveling on rails parallel to the plane of the opening of a mold. The carriage moves to and from a position between separated mold parts of the mold and a position outside of the mold. The carriage includes an upper frame structure capable of displacement in a direction at right angles to the rails, on which is mounted at least one form capable of matching, at least in part, the outward shape of the piece to be molded. The mold is connected to the upper structure by an intermediate means of variable geometry so as to allow a range of motion. A pneumatic means is included to retain the form in contact with the cast piece.
