Abstract

L'invention concerne un procédé de fabrication d'un modèle (30) en cire pour fabrication à cire perdue, caractérisé en ce qu'il comprend une étape d'injection de cire dans un moule d'injection cire métallique, de sorte à fabriquer au moins deux sous-modèles (10, 20) en cire identiques, une étape de jonction des sous-modèles (10, 20) en cire de sorte à former un modèle (30) en cire, et en ce qu'il comprend une étape préliminaire de conception des sous-modèles en cire, comprenant la définition de séries de points de références sur chaque sous-modèle en cire : une première série de six points de référence sur le sous-modèle en cire, permettant de bloquer chaque sous-modèle selon tous les degrés de liberté, une deuxième série de points de référence permettant de bloquer le modèle en cire formé par la jonction des sous-modèles en cire selon tous les degrés de liberté.The invention relates to a method of manufacturing a wax model (30) for manufacturing lost wax, characterized in that it comprises a step of injecting wax into a metal wax injection mold, so as to manufacture at least two identical submodels (10, 20) in wax, a step of joining the submodels (10, 20) in wax so as to form a model (30) in wax, and in that it comprises a preliminary stage of design of the wax submodels, including the definition of series of reference points on each wax submodel: a first series of six reference points on the wax submodel, making it possible to block each submodel model according to all the degrees of freedom, a second series of reference points making it possible to block the model in wax formed by the junction of the submodels in wax according to all the degrees of freedom.
