Claim:
An installation for the manufacture of ceramic products, the installation ( 100 ) comprising at least one mold ( 1 ) divided into at least two parts ( 2 , 3 ) forming an internal cavity (C) where the ceramic product is formed, and mobile towards and away from each other, under the action of respective drive means ( 4 ) acting in both directions along a predetermined clamping line (S), in such a way as to join or detach the parts ( 2 , 3 ) to/from each other; each part ( 2 , 3 ) of the mold ( 1 ) comprising at least one rear outside surface ( 2 p , 3 p ) and one lateral outside surface ( 2 s , 3 s ); wherein at least one of the parts ( 2 , 3 ) of the mold ( 1 ) is equipped with means ( 6 ) for containing and controlling a fluid, encompassing at least the rear outside surface ( 2 p , 3 p ) and the lateral outside surface ( 2 s , 3 s ) of the mold ( 1 ) part ( 2 , 3 ) and being associated with the part ( 2 , 3 ) of the mold ( 1 ) in such a way that during the product casting cycle the forces (SF) acting on the part ( 2 , 3 ) of the mold ( 1 ) are constantly compensated, wherein said containment and control means ( 6 ) comprise a hermetically sealed containment element ( 7 ) associated with the mold part ( 2 , 3 ) to surround the rear outside surface ( 2 p , 3 p ) and the lateral outside surface ( 2 s , 3 s ) of the mold part ( 2 , 3 ); said containment element ( 7 ) being equipped with means ( 8 ) for pumping compensation fluid in and out of a compensation chamber ( 9 ) defined between the containment element ( 7 ) itself and the rear ( 2 p , 3 p ) and lateral ( 2 s , 3 s ) outside surfaces of the mold part ( 2 , 3 ), wherein the containment element ( 7 ) comprises at least; a rigid element ( 22 ) defining the walls of the compensation chamber ( 9 ); a base plate ( 19 ) associated with the rigid element ( 22 ); sealing means ( 21 ) acting at least between the rigid element ( 22 ) and the mold part ( 2 , 3 ); a positioning or spacing element ( 17 ), located inside the rigid element ( 22 ) and associated bilaterally with the lateral outside surface ( 2 s , 3 s ) of the mold part ( 2 , 3 ) and to the base plate ( 19 ), through respective first and second fastening means ( 18 , 20 ), said element ( 17 ) being designed to position the mold part ( 2 , 3 ) relative to the base plate ( 19 ), wherein the base plate ( 19 ) is connected to means ( 4 ) for moving the mold part ( 2 , 3 ) and acting in both directions along a predetermined clamping line (S) in such a way as to join or detach the two parts ( 2 , 3 ) to/from each other.
