An assembly for manufacturing a wax moulding of a turbine engine blade has a wax injection mould in which a core is able to be mounted in a predetermined moulding position, the core including a main element and at least a first secondary element each including at least one functional part and a non-functional part, wherein the non-functional part of the first secondary element includes a rod portion extending in a longitudinal direction of the blade and housed in a first slot of the non-functional part of the main member, the mould including a first internal boss clamping said rod portion at the bottom of the first slot.

Assembly for manufacturing a turbine engine blade

The invention relates to the making, on a support plate (), of an annular space () in a ceramic paste covering this plate, in order, by successive deposits and firing of layers of said ceramic paste, to create a base of a ceramic shell () for the moulding of parts, the base having said annular space (). For this purpose, between two deposits of said ceramic paste, and on the plate, said deformable annular element () will be deformed in order to break the ceramic layer.

Manufacture of parts using the lost wax method

A method of making a multi-vane model for a nozzle guide out of sacrificial material, includes the steps of fabricating a single-vane model out of sacrificial material, assembling at least two sacrificial material single-vane models with each other, and positioning () a holder element on at least one sacrificial material single-vane model so as to hold a predetermined spacing between an inner platform and an outer platform. An assembly of a sacrificial material single-vane model for a nozzle guide together with a holder element, and also an assembly of a sacrificial material multi-vane model for a nozzle guide together with a holder element.

Method of making a multi-vane model, tooling, and an assembly comprising a multi-vane model and a holder element

A core used in the manufacture, by lost-wax casting, of a turbomachine blade, includes a main element and at least one first secondary element, each including a functional part and a non-functional part. The non-functional part of the main element and the non-functional part of the at least one first secondary element are assembled and shaped so as to cooperate with each other by sliding in a longitudinal direction extending between the base and the top of a blade and by rotating around the longitudinal direction.
