Abstract

LE MOULE COMPORTE UNE MOITIE FEMELLE PRESENTANT UNE SURFACE DE MOULAGE CONCAVE 3 ET UNE MOITIE MALE PRESENTANT UNE SURFACE DE MOULAGE CONVEXE 13. CES MOITIES SONT REUNIES PAR ADAPTATION EN BLOCAGE DE DEUX SURFACES D'ACCOUPLEMENT 4 ET 14 DEPENDANT RESPECTIVEMENT DE LA MOITIE FEMELLE ET DE LA MOITIE MALE. LES SURFACES 4 ET 14 SONT PLEINES, RIGIDES, CONTINUES ET ANNULAIRES. LA LENTILLE OBTENUE NE NECESSITE PAS D'USINAGE POSTERIEUR AU MOULAGE.
