<p>The present invention relates to a mould, in particular, for shaping unfired ceramic products. It can be used to make products of complex geometric shape using vertical-action presses, in which the surface of an upper buffer (3) in each cell (9) is so shaped that it can be superimposed by vertical displacement onto the surface of a fixed lower buffer (6) in such a way that the two surfaces almost meet. The 'soft' material is fed at room temperature through loading inlets (111) located in plates (11) which form the sides of each cell (9) and are in turn attached to a matrix (10) constituting the lower, mobile part of the mould. Feeding of the soft material through the loading inlets (111) into the cell (9), the form of which is defined above by the upper buffer (3), below by the lower buffer (6) and on each side by the plates (11), occurs while the cell is closed.</p> |
