UNIT FOR MOULDING A TURBOMACHINE BLADE, COMPRISING A RAISED PORTION WITH A LARGE CROSS-SECTION

摘要

The invention relates to a moulding unit (210) for producing a turbomachine blade blank. The moulding unit (210) has an upstream portion (270) and a downstream portion (280). According to the invention, the moulding unit (210) comprises a raised portion (231) designed to form a downstream opening which, at the level of the trailing edge, passes through at least one of the side edges of the basin-like portion at the blade tip. The raised portion (231) rigidly secures the upstream portion (270) to the downstream portion (280) and comprises a strengthening protuberance extending in the transverse direction.
