CLUSTER MODEL AND SHELL FOR OBTAINING AN ACCESSORY FOR THE INDEPENDENT HANDLING OF FORMED PARTS, AND ASSOCIATED METHOD

The invention relates principally to a cluster model and a shell (1) for the production, by lost wax casting, of a plurality of turbomachine elements, the shell (1) comprising a central sprue (3) thatis fluidically connected to 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 bottomfeed conduits (5) for the shell elements (4) and a handling accessory shell (6) that is independent of the plurality of shell elements (4) and of their metal supply circuit, such that there is no fluidic connection to the shell elements (4), the handling accessory shell (6) being fluidically connected to the central sprue (3) so as to allow top-pour casting of the handling accessory shell (6). 本发明主要涉及群集模型和用于通过失蜡铸造法生产多个涡轮机元件的壳体(1)，该壳体(1)包括流体地连接到铸造杯(2)以接收熔融金属的中心浇口(3)以及多个壳体元件(4)。壳体(1)的特征在于，该壳体进一步包括用于壳体元件(4)的多个底部进料管道(5)以及处理附件壳体(6)，该处理附件壳体独立于多个壳体元件(4)和多个壳体元件的金属供应回路，使得不存在到壳体元件(4)的流体连接，处理附件壳体(6)流体地连接到中心浇口(3)以允许对处理附件壳体(6)进行顶部浇
