Abstract

UN SISTEMA DE VACIADO POR INYECCION PARA TRANSPORTAR MATERIAL FUNDIDO DESDE UNA TOBERA CALIENTE DE LA PARTE SUPERIOR COLOCADA EN UN MOLDE DE CHAPA FIJO, HACIA UNA TOBERA DE LA PARTE INFERIOR CALIENTE, EN UN MOLDE DE CHAPA MOVIL. LAS TOBERAS SUPERIOR E INFERIOR TIENEN UNA BOCA CON UNA PARTE DELANTERA QUE SE APOYA LA UNA EN LA OTRA EN LA LINEA DE DIVISION DE LA POSICION CERRADA. EL PASO DEL MATERIAL FUNDIDO A TRAVES DEL CENTRO DEL APARATO; EL MATERIAL FUNDIDO PENETRA EN LAS TOBERAS QUE SE ESTRECHAN INTERIORMENTE ADYACENTES A LAS PARTES DELANTERAS PARA FORMAR UN ORIFICIO DE ENTRADA POR EL CUAL PASA DICHO MATERIAL. MIENTRAS QUE AMBAS TOBERAS TIENEN UN ELEMENTO INTEGRAL DE CALENTAMIENTO ELECTRICO, UNICAMENTE EL ELEMENTO CALENTADOR DE LA TOBERA SUPERIOR TIENE UNA PORCION CIRCULAR SOLDADA A LA BOCA PARA INTRODUCIR EL MATERIAL FUNDIDO Y DAR MAS CALOR Y MEJOR CONTROL CERCA DEL ORIFICIO DE SALIDA. ANTES DE QUE SE ABRA EL MOLDE POR SU MITAD PARA EXPULSAR MIENTRAS DURA EL CICLO DE INYECCION, EL PODERDE LOS ELEMENTOS CALORIFICOS SE DESCONECTA PARA PERMITIR LA ENTRADA DEL MATERIAL FUNDIDO POR EL ORIFICIO DE ENTRADA.
