Abstract

Le présent document concerne un moule (34) pour procédé de fabrication d’un noyau en céramique de fonderie destiné à former au moins une partie d’une aube, le moule (34) comprenant une empreinte (40), l’empreinte (40) comprenant une première zone (42) destinée à former une première zone du noyau et une seconde zone (44) destinée à former une seconde zone du noyau, lesdites zones (42, 44) de l’empreinte (40) étant décalées l’une de l’autre, le moule (34) comportant au moins un canal principal d’alimentation (48) débouchant dans la première zone (42) de l’empreinte (40) et un logement (46) reliant les première et seconde zones (42, 44), ledit logement (46) étant destiné à permettre l’insertion d’une tige de liaison (52) reliant les première et seconde zones du noyau, caractérisé en ce qu’il comprend au moins deux canaux auxiliaires d’alimentation (54) s’étendant de part et d’autre de la première zone (42) de l’empreinte (40) et débouchant dans la seconde zone (44) de l’empreinte (40). Figure à publier avec l’abrégé : Figure 7.This document relates to a mold (34) for a method of manufacturing a foundry ceramic core intended to form at least part of a blade, the mold (34) comprising a cavity (40), the cavity (40 ) comprising a first zone (42) intended to form a first zone of the core and a second zone (44) intended to form a second zone of the core, said zones (42, 44) of the cavity (40) being offset from the other, the mold (34) comprising at least one main supply channel (48) opening into the first zone (42) of the cavity (40) and a housing (46) connecting the first and second zones (42, 44), said housing (46) being intended to allow the insertion of a connecting rod (52) connecting the first and second zones of the core, characterized in that it comprises at least two auxiliary channels of supply (54) extending on either side of the first zone (42) of the cavity (40) and opening into the second zone (44) of the cavity (40). Figure to be published with abstract: Figure 7.
