| description | L'invention concerne le domaine de la fonderie monocristalline, et en particulier une cavité de démarrage (10) pour fonderie monocristalline, comprenant au moins un premier volume (10a) en forme d'entonnoir inversé, et un deuxième volume (10b) distinct en forme de socle à la base du premier volume et sensiblement en saillie par rapport audit premier volume dans au moins une direction horizontale. L'invention concerne aussi un moule (1) comprenant une telle cavité de démarrage (10) et un procédé de fonderie utilisant un tel moule (1), ainsi qu'un modèle fusible (10') d'une telle cavité de démarrage (10).
The invention relates to the field of monocrystalline casting, and in particular to a mold (1) for monocristalline casting comprising at least a molding cavity (7), a starter cavity (10) having at least a first volume (10a) in the form of an upside-down funnel, and a distinct second volume (10b) forming a plinth at the bottom of the first volume and projecting perceptibly relative to said first volume in at least one horizontal direction, a selector channel (9) connecting said starter cavity (10) to said molding cavity (7), and a support rod (20) that is laterally offset relative to said selector channel, and that connects the second volume (10b) of the starter cavity (10) to the molding cavity (7). The invention also provides a casting method using such a mold (1). |
