| 内容： | A porous mould for making sanitaryware comprises: two half-parts (2, 3) joined to each other to create a product forming cavity (4); one of the half-parts (2) has a first inlet opening (5) through which respective means (6) feed a liquid (7) under pressure into the product forming cavity (4); a variable volume element (8) located inside the cavity (4); second means (10) for feeding a fluid under pressure, acting on this element (8) and varying the volume of the element (8) between at least two limit states, namely, a least expanded, idle state and a most expanded working state, when the forming liquid (7) is fed in, and where the element (8) occupies a predetermined volume of the cavity (4) in such a way as to control the inflow of the liquid (7) along the surfaces of the cavity (4); means (11) for controlling and regulating the degree to which the element (8) is filled and the liquid (7) feed pressure, acting on the respective first feed means (6) and second feed means (10) in such a way as to correlate the feed pressures according to the extent to which the cavity (4) has been filled by the liquid (7). |
