ABSTRACT:
An installation (100) for the manufacture of ceramic products comprises a 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) comprises at least one rear outside surface (2p, 3p) and one lateral outside surface (2s, 3s); at least one of the parts (2, 3) is equipped with means (6) for containing and controlling a fluid and encompassing the rear (2p, 3p) and lateral (2s, 3s) outside surfaces of the mold (1) part (2, 3); the containment means (6) are 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 by correlated forces (FR).
