Abstract
PERFECTIONNEMENT AU MOULAGE DE COEURS DE CROISEMENT POUR APPAREILS DE VOIES, AVEC EVIDEMENTS INFERIEURS ET LOGEMENTS D'ECLISSAGE AVEC LES RAILS DE RACCORDEMENT. ON UTILISE UNE SEULE BOITE A NOYAU MONOBLOC REPRENANT LA TOTALITE DES EVIDEMENTS INFERIEURS. ON PLACE LA BOITE A NOYAU MONOBLOC DANS L'EMPREINTE CREUSE EN SABLE DU MODELE; ON FORME ENSUITE LE NOYAU DES EVIDEMENTS INFERIEURS ET LE SERRAGE DU SABLE DU CHASSIS DE DESSUS AVEC LA BOITE A NOYAU TOUJOURS EN PLACE DANS L'EMPREINTE CREUSE. LA BOITE A NOYAU EST ENLEVEE APRES SEPARATION DE DEUX CHASSIS. L'INVENTION S'APPLIQUE A LA FABRICATION DES COEURS DE CROISEMENT EN ACIER AU MANGANESE MOULE.IMPROVEMENT IN THE MOLDING OF CROSSING HEARTS FOR TRACK UNITS, WITH LOWER RECESSES AND SLIDING HOUSINGS WITH CONNECTION TRACKS. A SINGLE MONOBLOC CORE BOX IS USED WITH ALL OF THE LOWER RECESSES. THE MONOBLOC CORE BOX IS PLACED IN THE HOLLOW SAND PRINT OF THE MODEL; THE CORE IS THEN SHAPED OF THE BOTTOM CHASSIS AND THE CLAMPING OF THE SAND OF THE TOP CHASSIS WITH THE CORE BOX STILL IN PLACE IN THE HOLLOW RECESS.
