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. THE CORE BOX IS REMOVED AFTER TWO CHASSIS SEPARATION. THE INVENTION APPLIES TO THE MANUFACTURING OF MOLDED MANGANESE STEEL CROSSING HEARTS.
