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.

Abstract: Pressure-casting bench for vitreous china sanitary fixtures having two guides on which mold parts travel in a horizontal direction, capable of pairing so as to bound a molding cavity, a set of guides or rails being provided for introducing into and removing from the cavities so bounded, additional mold parts known as mandrels. An upper support structure is provided capable of supporting a horizontal beam and causing it to travel in a plane at right angles to the plane defined by the guides under which all the mandrels are fixed in order to enter the molding cavities. A series of plates, spindles and springs are provided for the mandrels as well as a series of pegs for clamping the mandrels to the mold parts thereunder and encasing the molding cavities and subsequently releasing the mandrels from the mold parts.
