Abstract

S UPPORT DE STOCKAGE D ’ UNE PIECE EN CIRE PERDUE Un aspect de l’invention concerne un support de stockage (4) d’une pièce en cire perdue (4) en forme d’un distributeur basse pression (1), caractérisé en ce qu’il comprend : - cinq lignes parallèles (40, 41, 42) et en relief dont trois lignes (40) de même hauteur placées entre deux lignes latérales (41, 42) de hauteur inférieure et - deux plots (43, 44, 45) de hauteur supérieure aux lignes parallèles (40, 41, 42). Cette géométrie du support permet de répartir la charge sur de nombreux points d’appui et donc de limiter fortement les déformations de la pièce en cire perdue. On n’observe ainsi aucune déformation des pales grâce aux trois points d’appui. Les appuis au niveau de chaque plateforme et de la venue de cire permettent une répartition uniforme de la charge Figure à publier avec l’abrégé : Figure 3S UPPORT FOR STORAGE OF A LOST-WAX PIECE One aspect of the invention relates to a storage support (4) for a lost-wax piece (4) in the form of a low-pressure distributor (1), characterized in that that it comprises: - five parallel lines (40, 41, 42) and in relief including three lines (40) of the same height placed between two lateral lines (41, 42) of lower height and - two studs (43, 44, 45) higher than the parallel lines (40, 41, 42). This geometry of the support makes it possible to distribute the load over many points of support and therefore to greatly limit the deformations of the lost wax part. There is thus no deformation of the blades thanks to the three support points. Sills at each platform and wax rise allow even load distribution Figure to be published with abstract: Figure 3
