Abstract
A moulding unit for producing a turbomachine blade blank. The moulding unit has an upstream portion and a downstream portion. According to the invention, the moulding unit comprises a raised portion 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 rigidly secures the upstream portion to the downstream portion and comprises a strengthening protuberance extending in the transverse direction.
