Abstract

Système de fixation des deux moitiés de fû t d’un moule d’injection d’un carter de soufflante Moule (400) destiné à être utilisé pour la fabrication d’un carter de soufflante de turbine à gaz en matériau composite comprenant un mandrin sur lequel est destinée à être enroulée une préforme fibreuse de carter de soufflante comprenant une paroi annulaire dont le profil de la surface extérieure correspond à celui de la surface interne du carter à fabriquer et deux flasques latéraux dont les profils correspondent à ceux de brides externes du carter à fabriquer, la paroi annulaire étant formée d’un premier et d’un deuxième demi-fûts (411, 412) assemblés entre eux par au moins un système vis-écrou, caractérisé en ce que ledit système vis-écrou comprend : une vis (421) placée sur une surface du premier demi-fût (412) et insérée dans un premier trou présent dans le premier demi-fût (412) et dans un deuxième trou présent dans le deuxième demi-fût (411), etun écrou (422) intégré à une plaque (423) fixée sur une surface du deuxième demi-fût (411) et la vis étant vissée dans l’écrou.
