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.

Abstract: A plant including at least two parallel casting benches (1), each comprising a plurality of double-face moulds (3) which can be clamped together into a pack so as to define a succession of vertical cavities for casting shaped concave vitreous china objects (6); means (13) for rapidly drying the moulds of each casting bench; at least one vertical parking unit (4) in the form of superposed shelves lying between said two casting benches and arranged to accumulate the articles during their hardening stage; means (5) for transferring the articles, after being withdrawn from the moulds, from the two casting benches to a motorized holding table (11) provided at the base of said vertical parking unit; end lifting-lowering means (8), (88) for loading and unloading this latter; means (18), disposed at the discharge end of said vertical parking unit, for automatically loading the articles on to fork trucks (20); at least one rotatable platform (19) for these latter; a drier (23) through which the full fork trucks pass;
