Abstract

UN METODO PARA LA FABRICACION DE UNA TOBERA DE MOLDEO POR INYECCION QUE TIENE UN ELEMENTO DE CALENTAMIENTO ELECTRICO (28) ENROLLADO EN UN CANAL (18). EL ELEMENTO DE CALENTAMIENTO (28) TIENE DOS ALAMBRES TERMINALES (40) QUE SE EXTIENDEN RADIALMENTE HACIA AFUERA PARALELOS ENTRE SI DESDE BIEN UNA PORCION FINAL COMUN O DOS PORCIONES FINALES SEPARADAS (30) DEL ELEMENTO DE CALENTAMIENTO. TRAS ENROLLAR EL ELEMENTO DE CALENTAMIENTO (28) EN EL CANAL EN ESPIRAL (18) QUE HAY EN EL CUERPO DE LA TOBERA (10) SE MONTAN UNAS PORCIONES DE COLLAR DELANTERAS Y TRASERAS (46,60) ALREDEDOR DEL CUERPO DE LA TOBERA (10) PARA FORMAR UNA RANURA RADIAL O APERTURA (72) ENTRE ELLAS A TRAVES DE LAS CUALES SE PROYECTAN LA PORCION O PORCIONES FINALES (30) DEL ELEMENTO DE CALENTAMIENTO. HAY MONTADA UNA PORCION DE PERNO (84) DE MODO QUE SE EXTIENDA RADIALMENTE HACIA AFUERA DESDE LA RANURA (72) CON UN SOLO AGUJERO O DOS AGUJEROS PARALELOS (86) A TRAVES DE LOS CUALES SE EXTIENDE LA PORCION O PORCIONES FINALES (30). ESTOS COMPONENTES SE SUELDAN ENTONCES ENTRE SI EN UN HORNO DE VACIO PARA FORMAR UNA ESTRUCTURA SOLIDARIA FUERTE CON LA PORCION O PORCIONES FINALES (30) DEL ELEMENTO DE CALENTAMIENTO (28) ASEGURADO EN SU LUGAR CORRESPONDIENTE. EN UN ASPECTO DE LA INVENCION, SE MONTA UNA PORCION SEPARADORA (152), QUE TIENE DOS AGUJEROS PARALELOS (156), CON UNA PASTA DE CERAMICA A LA PORCION DE PERNO (142). LOS DOS ALAMBRES TERMINALES (40) SE EXTIENDEN HACIA AFUERA A TRAVES DE LOS AGUJEROS PARA LA CONEXION EN UNA TAPA ROSCADA (168) A UN PAR DE HILOS CONDUCTORES QUE HAY EN EL EXTERIOR (128).
