Assembly for producing a molding made of removable material of a turbomachine

A method for producing a molding, made of removable material, of a turbomachine blade, the method comprising:

• providing a first core element and a second core element, said core elements extending in a first direction;
• and
• providing an injection mold for said removable material,
• wherein the mold comprises:
• a first molding face configured to mold a pressure-side face of the blade and a second molding face configured to mold a suction-side face of the blade and arranged facing the first face in a second direction perpendicular to the first direction;
• and
• retaining members configured to hold the cores in position in the injection mold, among which at least a first retaining member extends from the first molding face in the second direction,
• the method further comprising the step of positioning the first core element and the second core element on the first molding face such that the first retaining member extends at least partially through the first and second core elements and comprises a first support point at which the first retaining member bears against the first core element and a second support point at which the first retaining member bears against the second core element.
