Abstract

EN UN PROCEDIMIENTO PARA LA COLADA DE ARTICULOS EN LAS CAVIDADES (NO MOSTRADAS) DE UN MOLDE DE ARENA (1), EN QUE SE UTILIZA UNA UNIDAD DE ALIMENTACION (4) PARA INTRODUCIR UN METAL FUNDIDO (NO MOSTRADO) EN DICHAS CAVIDADES A TRAVES DE UN CANAL DE COLADA (2), LA NUEVA CARACTERISTICA PRINCIPAL ES EL USO DE UN ELEMENTO ELASTICO DE ESTANQUEIDAD, EN EL EJEMPLO MOSTRADO UN ARO (8), HECHO PREFERENTEMENTE DE UN MATERIAL TERMOAISLANTE PARA OBTENER UNA JUNTA ESTACA ALREDEDOR DE LA CONEXION ENTRE UN BOQUILLA (3) DISPUESTA SOBRE DICHA UNIDAD (4) Y EL CANAL DE COLADA (2), CUANDO LA UNIDAD (4) SE MUEVE A LA POSICION DE LLENADO MOSTRADA. EL USO DEL ARO DE ESTANQUEIDAD (8) PERMITE EVITAR QUE LA ARENA DEL MOLDE CONTAMINE DE LA BOQUILLA (3), ASI COMO LA SOLIDIFICACION DEL METAL FUNDIDO SOBRE LA BOQUILLA, QUE DE LO CONTRARIO IMPEDIRIA LA CORRECTA COOPERACION DE LA BOQUILLA CON EL SIGUIENTE MOLDE DE LA FILA A LLENAR.IN A PROCEDURE FOR CASTING ITEMS IN THE CAVES (NOT SHOWN) OF A SAND MOLD (1), IN WHICH A FEED UNIT (4) IS USED TO INTRODUCE A CAST METAL (NOT SHOWN) IN SUCH CAVITIES THROUGH A CASTING CHANNEL (2), THE NEW MAIN FEATURE IS THE USE OF AN ELASTIC SEALING ELEMENT, IN THE EXAMPLE SHOWN A RING (8), PREFERABLY MADE OF A THERMAL INSULATING MATERIAL TO OBTAIN A STAIN GASKET AROUND THE CONNECTOR (3) PROVISION ABOUT SUCH UNIT (4) AND THE COLADA CHANNEL (2), WHEN THE UNIT (4) IS MOVED TO THE FILLING POSITION SHOWN. THE USE OF THE SEALING RING (8) ALLOWS TO PREVENT THE SAND OF THE MOLD CONTAMINATING FROM THE NOZZLE (3), AS WELL AS THE SOLIDIFICATION OF THE MELTED METAL ON THE NOZZLE, WHICH WOULD OTHERWISE PREVENT THE CORRECT COOPERATION OF THE NOZZLE WITH THE FOLLOWING MOLD FROM THE ROW TO FILL.
