Isostatic mold, particularly for ceramic tiles

摘要

An isostatic mold (1), particularly for ceramic tiles, comprising at least one forming receptacle (2) which is delimited in an upper region by a first mold part (3) and in a lower region by a respective second mold part (4), at least one of the mold parts comprising a closed compression chamber (5) which accommodates a working liquid. The compression chamber (5) has a volume delimited by a first face (6) of a punch (8) and by a corresponding sliding seat (9). The punch (8) is associated slidingly and hermetically with the sliding seat (9) for its transition from an inactive position to a pressing position and vice versa; in particular in the pressing position the compression chamber (5) defines a smaller volume than the volume it defines in the inactive position. An external hydraulic circuit (10) being functionally connected to the compression chamber (5) to control the pressure of the working liquid.
