Abstract

Uno stampo per la formatura di manufatti ceramici comprende gusci (17, 17') in materiale poroso, di spessore genericamente costante, riproducenti internamente la matrice del manufatto da stampare e aventi esternamente una pluralità di scanalature intercollegate (19, 19'). Detti gusci sono ricoperti da corpi (22, 22') in materiale non poroso a formare un generico parallelepipedo così da essere comprimibili assieme fra piani di pressa (27). Le scanalatura intercollegate (19, 19') formano una rete di condotti interconnessi con l'esterno attraverso condotti (23, 23') ricavati nei corpi non porosi (22, 22').Un metodo realizzativo dello stampo comprende le fasi di formare i gusci (17, 17') in materiale poroso con sulla loro superficie esterna una rete di scanalature; chiudere dette scanalature (19, 19') alla superficie dei gusci mediante strisce (20, 20') per formare una rete di canalizzazioni; formare un corpo (22, 22') su ogni guscio (17, 17') con almeno un condotto (23, 23') sfociante nella rete di scanalature (19, 19').A mold for the formation of ceramic articles comprises shells (17, 17 ') in porous material, of generally constant thickness, internally reproducing the matrix of the article to be printed and externally having a plurality of interlinked grooves (19, 19'). Said shells are covered by bodies (22, 22 ') in non-porous material to form a generic parallelepiped so as to be compressible together between press surfaces (27). The interconnected grooves (19, 19 ') form a network of conduits interconnected with the outside through conduits (23, 23') obtained in the non-porous bodies (22, 22 '). A mold construction method comprises the steps of forming the shells (17, 17 ') in porous material with a network of grooves on their external surface; closing said grooves (19, 19 ') to the surface of the shells by means of strips (20, 20') to form a network of channels; forming a body (22, 22 ') on each shell (17, 17') with at least one conduit (23, 23 ') leading into the network of grooves (19, 19').
