Pressure casting apparatus utilizing with two-part moulds

An apparatus for pressure casting sanitary appliances, which comprises

• an outer framework,
• at least one block slidable within said outer framework and including a male mould part and a female mould part,
• a fixed endpiece of said framework being provided with the male part which is to be inserted into the female part of said one block,
• a movable head of said framework being provided with the female mould part which is adapted to receive the male part of said one block,
• means for thrusting the movable head in the direction of the fixed endpiece, and means for introducing pressurized slip into cavities which are formed when said blocks are positioned one against the other, wherein a mould portion which defines a tile cavity of the female mould part is surrounded by a frame which is open on at least two sides, said mould portions and said frame defining a space therebetween which is provided with an inflatable element containing a pressurized fluid.

An apparatus for pressure casting sanitary appliances, which comprises:

• an outer framework;
• at least one block slidable in a first direction within said outer framework and including a male mould part and a female mould part;
• a fixed endpiece of said framework being provided with the male part which is to be inserted in the first direction into the female part of said one block;
• a movable head of said framework being provided with the female mould part which is adapted to receive in the first direction the male part of said one block, said female mould part having at least one wall which is deformable in second direction;
• means for thrusting the movable head in the direction towards the fixed endpiece in the first direction, and means for introducing pressurized slip into cavities which are formed when said blocks are positioned one against the other;
• at least one frame for surrounding the mould portion which defines the tile cavity of the female mould, defining a space between the at least one frame and the mould portion;
• at least one inflatable element containing a pressurized fluid positioned in the space between the at least one frame and the mould portion, said at least one inflatable element acting on the at least one wall of the female mould part in the second direction;
• and
• wherein the first direction and the second direction are substantially orthogonal relative to each other.
