Abstract

The present invention relates to a shell mould (200) for manufacturing aircraft turbomachine bladed elements using the lost wax moulding technique and comprising: shell mould bladed elements (1b) comprising a blade portion (2b) situated between a first end part (4b) delimiting the impression of a platform (8b) and a second end part (6b) delimiting the impression of another platform (8b) the blade portion comprising a trailing edge zone (30b); a metal feeder (12b) having a central axis (14b) around which the bladed elements (1b) are distributed; and according to the invention the shell mould is equipped with one or a number of screens (29b) that form accumulators of heat and are arranged in a shell mould interior space (28b) facing the inwardly directed trailing edge zones (30b).
