Casting installation

A casting installation for casting slip into a ceramic product, said casting installation comprising:

• a pressure container,
• an inner surface of said pressure container defining an opening extending through said container,
• at least one casting mold adapted to be located in said opening of said pressure container so as to establish a space which surrounds said at least one casting mold,
• said casting mold being composed of a plurality of separate mold parts each having a plurality of channels therein and having its respective outer face treated to be fluid-tight,
• an inner molding surface of said mold parts, when assembled, being dimensioned to define a molding cavity of said at least one casting mold,
• said space being in communication with said molding cavity of said at least one casting mold,
• means for firmly clamping said at least one casting mold,
• means operatively connected to said channels of said mold parts for depressurizing said mold parts,
• a source of slip operatively connected to said molding cavity of said at least one casting mold, and
• a pressurized water source operatively connected to said space surrounding said at least one casting mold.

A casting installation for casting slip into a ceramic product, said casting installation comprising:

• a pressure container having a wall formed on the inner surface thereof so as to define an opening through the container,
• at least one porous casting mold adapted to be located in said opening of said pressure container so as to establish a space which surrounds said at least one casting mold,
• said at least one casting mold being composed of a plurality of separate mold parts each having a plurality of channels therein and assembled to define a molding cavity of said at least one casting mold,
• means for firmly clamping said at least one casting mold,
• means operatively connected to said channels of said mold parts for depressurizing said mold parts,
• means for supplying slip from a slip source into said molding cavity of said at least one casting mold,
• auxiliary slip supply reservoir means located outside said casting mold within said pressure container and communicating with said molding cavity for supplying additional slip into said molding cavity,
• said auxiliary slip supply reservoir means opening into said space surrounding said casting mold, and
• means for pressurizing said space surrounding said casting mold with air under pressure to equalize the pressures in said space and said molding cavity.
