摘要

The invention relates to a core (16) for molding a blade, said core (16) comprising a first element (17) for delimiting a first cavity and a second element (18), at least a portion (19) defining a second cavity located between the first cavity and the apex of the blade, in which: the portion (19) of the second element (18) comprises a through-hole (26) which opens at the right of the first element (17) to delimit in the molded blade an outer face of a dedusting duct of the first cavity; - an alumina rod (27) extending in the through hole (26) being fixed to the end face (28) of the first element (17), to define the inner face of the conduit; - Centering means (29) interposed between the rod (27) and the through hole (26) to center the rod relative to the hole (26), these centering means (29) being of a material intended to be dissolved before pouring dawn around said core (16).
