| 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 ). |
