Abstract

MODELE ET PROCEDE DE MOULAGE POUR COEURS DE VOIES COMPORTANT DES EVIDEMENTS INFERIEURS, DES LOGEMENTS D'ECLISSAGE EN BOUT DES BRANCHES DE RACCORDEMENT, ET DES SEMELLES D'APPUI SUR TRAVERSES. ON UTILISE UN MODELE A DEUX FACES, REPRODUISANT A LA FOIS LES FORMES EXTERIEURES ET TOUS LES EVIDEMENTS INFERIEURS. ON SERRE D'ABORD LE SABLE SUR LE DESSUS DU MODELE, DANS UN CHASSIS DE DESSOUS, PUIS APRES RETOURNEMENT ON FORME LES MOTTES DANS LES CREUX INFERIEURS DU MODELE, ET ON SERRE LE SABLE DANS LE CHASSIS DE DESSUS. ON SEPARE LES CHASSIS AVEC DEBOITAGE DU MODELE DU CHASSIS DE DESSOUS ET, APRES RETOURNEMENT, ON ENLEVE LE MODELE POUR DEMOULER LES MOTTES. L'INVENTION S'APPLIQUE AU MOULAGE DES COEURS DE VOIES POUR AIGUILLAGES OU TRAVERSEES DE CHEMIN DE FER.MODEL AND METHOD OF MOLDING FOR CORE OF TRACKS INCLUDING LOWER RECESSES, SLIDING HOUSINGS AT THE END OF THE CONNECTING BRANCHES, AND SUPPORTING SIDES ON CROSSERS. A TWO-SIDED MODEL IS USED, REPRODUCING BOTH THE EXTERNAL SHAPES AND ALL THE LOWER RECESSES. FIRST SAND THE SAND ON THE TOP OF THE MODEL, IN A CHASSIS BELOW, THEN AFTER TURNING, FORM THE MOUNDS IN THE LOWER HOLLOWS OF THE MODEL, AND SAND IN THE FRAME ABOVE. THE CHASSIS ARE SEPARATED WITH THE MODEL DISCONNECTED FROM THE CHASSIS FROM BELOW AND, AFTER TURNING OVER, THE MODEL IS REMOVED TO UNMOLD THE CLODS.
