Abstract (en)
A mould for manufacturing ceramic articles comprises shells (17, 17') made of porous material, of a generically constant thickness, internally reproducing the matrix of the article to be moulded and externally provided with a plurality of interconnected grooves (19, 19'). Said shells are covered by casings (22, 22') made of non-porous material to form a generic parallelepipedon to enable them to be pressed together between press plates (27). The interconnected grooves (19, 19') form a network of ducts interconnected with the outside by means of ducts (23, 23') made in the non-porous casings (22, 22'). A method for manufacturing the mould comprises the steps of moulding the shells (17, 17') made of porous material with a network of grooves on their outer surface, of closing said grooves (19, 19') on the surface of the shells by means of strips (20, 20') to form a network of ducts, and of moulding a casing (22, 22') onto each shell (17, 17') with at least one duct (23, 23') leading into the network of grooves (19, 19'). <IMAGE>
