CLUSTER-SHAPED MODEL AND CARAPACE FOR OBTAINING AN INDEPENDENT HANDLING ACCESSORY FOR SHAPED PARTS AND ASSOCIATED METHOD

摘要

The main object of the invention relates to a cluster-shaped model and a shell (1) for the lost-wax molding of a plurality of turbomachine elements, the shell (1) comprising a central descendant (3). ) in fluid communication with a casting cup (2) for receiving the molten metal and a plurality of shell elements (4). The shell (1) is characterized in that it further comprises a plurality of source supply ducts (5) of the shell elements (4) and a handling accessory shell (6), independent of the plurality of carapace elements (4) and their metal supply circuit so as to be without fluid communication with the carapace elements (4), the handling accessory carapace (6) being in fluid communication with the descendant central (3) to allow a fall casting of the carapace handling accessory (6).
