Abstract

Ensemble pour la réalisation d’un moulage en matériau éliminable d’une aube de turbomachine comprenant un moule d’injection dudit matériau éliminable dans lequel un premier élément de noyau (22) et un second élément noyau (21) sont aptes à venir se monter dans une position prédéterminée de moulage, les premier et second éléments noyaux (21, 22) s’étendant selon une première direction (Z), le moule comprenant :- une première face (20) pour le moulage d’une face intrados de l’aube et une seconde face pour le moulage d’une face extrados de l’aube agencée en vis-à-vis de la première face selon une deuxième direction (Y) perpendiculaire à la première direction (Z), - des organes de maintien (P1a, P1f, P2a, P2f, P3a, P3f, P6a, P6f, P6’f) en position des noyaux dans le moule d’injection, caractérisé en ce que la première face de moulage (20) comprend au moins un premier organe de maintien (P1a, P1f, P2a, P2f, P3a, P3f) s’étendant depuis la première face de moulage (20) selon la deuxième direction (Y), ledit premier organe de maintien (P1a, P1f, P2a, P2f, P3a, P3f) comprenant un premier point d’appui sur une première surface d’appui d’un élément de noyau (21, 22), la première surface d’appui s’étendant contre l’élément de noyau (21, 22), pour le maintien en position dudit élément de noyau suivant la deuxième direction (Y). Figure de l’abrégé : Figure 1Assembly for producing a mold of a turbomachine blade from disposable material, comprising an injection mold for said disposable material, in which a first core element (22) and a second core element (21) are adapted to be mounted in a predetermined molding position, the first and second core elements (21, 22) extending along a first direction (Z), the mold comprising: - a first face (20) for molding an intrados face of the blade and a second face for molding an extrados face of the blade arranged opposite the first face along a second direction (Y) perpendicular to the first direction (Z), - retaining elements (P1a, P1f, P2a, P2f, P3a, P3f, P6a, P6f, P6’f) in position of the cores in the injection mold, characterized in that the first molding face (20) comprises at least one first retaining element (P1a, P1f, P2a, P2f, P3a, P3f) extending from the first molded face (20) along the second direction (Y), said first retaining member (P1a, P1f, P2a, P2f, P3a, P3f) comprising a first bearing point on a first bearing surface of a core element (21, 22), the first bearing surface extending against the core element (21, 22), for holding said core element in position along the second direction (Y).
