Abstract

UNA TOBERA (26) ESTA COLOCADA EN LA CABEZA DE CONEXION (14) DE UNA TOBERA DEL CANAL DE CALEFACCION (10) PARA UNA PLACA DE NIDO A MOLDEAR (18) DE UN CANAL PRINCIPAL (22) CALEFACTOR. LA TOBERA (26) TIENE UNOS SALIENTES-GUIA (28) DE BLOQUEO Y DESPLAZABLES EN SU EXTREMO INFERIOR (27), BUENOS CONDUCTORES DEL CALOR, EN RELACION CON EL NIDO DE MOLDEO. ESTOS SALIENTES SE PUEDEN SEPARAR DE UN SOPORTE (30), CONDUCTOR DEL CALOR, O ESTAN FIJOS EN SU INTERIOR, EL CUAL ENCIERRA UN SALIENTE (27) CILINDRICO Y CONCENTRICO DE LA TOBERA Y QUE SE COLOCA, POR ENCIMA DE UN ANILLO DE SOPORTE DE DISTANCIA (34), EN LA TOBERA (26) MEDIANTE UNOS BRAZOS QUE SON MALOS CONDUCTORES DEL CALOR O, TAMBIEN SE PUEDEN COLOCAR EN LA PLACA DE NIDO A MOLDEAR (18) ANTES DE SU REALIZACION. LOS SALIENTES-GUIA (28) ESTAN COLOCADOS TRANSVERSALMENTE O CON TENDENCIA HACIA EL EJE (12) DE LA TOBERA (26). EN CASO DE QUE EN EL CANAL PRINCIPAL (22) Y/O EN LOS CANALES LATERALES SE ENCUENTRE POR EJEMPLO UNA AGUJA DE CIERRE (50) EN FORMA DE SELLO, SE AÑADIRA A SU FONDO UN MEDIO REFRIGERANTE MEDIANTE UNA TUBERIA DOBLE (52) CON AVANCE Y RETORNO INTERIOR (54 O 56). UN NUCLEO (62) QUE SE MUEVE EN FORMA LONGITUDINAL DENTRO DEL CANAL (22, 24) DEJA LIBRE, EN UNA POSICION TRASERA, A UNA TOBERA ANULAR DE INYECCION (68), QUE MEDIANTE EL DESPLAZAMIENTO DEL NUCLEO (62) SE PUEDE CERRAR EN PARTE O TOTALMENTE.
