FIELD: metallurgy.
SUBSTANCE: mould set contains a water-absorbing matrix located in a metal frame, a core and a boosting unit. At that, the water-absorbing matrix is made of a porous polymer that fills the entire volume formed by the outer contour of the workpiece and the frame. In the body of the matrix, there are channels with a diameter from 2 to 15 mm, located from the base of the frame to the working surface of the matrix. The distance between the centers of the channels, as well as from the working surface of the matrix to the end of the channel, is from 15 to 40 mm. The matrix in the area of the frame base is made with a gap, and the frame has branch pipes for supplying air and water under pressure to this gap. The boosting unit contains a branch pipe for feeding slurry under pressure.
EFFECT: increased productivity of mould sets for forming complex ceramic workpieces.
