Abstract

L'INVENTION VISE A COMPENSER ECONOMIQUEMENT LE RETRAIT DE LA RESINE COULEE DANS UN MOULE, AFIN D'EVITER TOUT DEFAUT D'ASPECT, RETASSURE OU INCLUSION DANS LA PIECE MOULEE. SUIVANT L'INVENTION, ON INTERPOSE ENTRE UN DEMI-MOULE INFERIEURE 16 ET UN APPUI 10 AUQUEL LE DEMI-MOULE SUPERIEUR 18 EST RELIE PAR DES TIRANTS 36 UN COUSSIN DE PRESSION 12 QUE L'ON PEUT GONFLER AVEC UN FLUIDE SOUS PRESSION. LES DEUX DEMI-MOULES 16 ET 18 SONT DE PREFERENCE MAINTENUS A L'ECARTEMENT APPROPRIE POUR FIXER L'EPAISSEUR DE LA PIECE MOULEE AU MOYEN DE CALES 46 PENDANT LA COULEE ET JUSQU'A LA GELIFICATION DE LA RESINE. LE JOINT ENTRE LES DEUX DEMI-MOULES EST DE PREFERENCE FERME PAR UNE GARNITURE SOUPLE ET GONFLABLE A APPUI RADIAL 24.
