Abstract

UN SISTEMA DE MOLDEO POR INYECCION CON VALVULA DE SALIDA, TENIENDO UN NUEVO MIEMBRO DE VALVULA PARA UN GRAN VOLUMEN DE APLICACIONES. EL MIEMBRO VALVULA ALARGADO TIENE UNA PARTE ENCARRUJADA AISLANTE ENTRE LA PORCION PRINCIPAL DE ACERO Y UNA PARTE CONDUCTORA ADYACENTE AL EXTREMO DE LA PUNTA. LA PARTE CONDUCTORA PROVEE ENFRIAMIENTO MAS RAPIDO CUANDO EL EXTREMO DE LA PUNTA ESTA APOYADO EN LA PUERTA EN LA POSICION DE CIERRE. LA PARTE AISLANTE ADYACENTE PROVEE UNA BARRERA TERMICA PARA REDUCIR EL FLUJO DE CALOR A LO LARGO DE LA VALVULA EN LA PORCION CONDUCTORA. ESTA COMBINACION IMPIDE QUE EL EXTREMO DE LA PUNTA SE QUEDE PEGADA CUANDO SE ABRE EL MOLDE Y PERMITE POR ESTO QUE LA DURACION DEL CICLO SEA REDUCIDA. LA PORCION CONDUCTORA TIENE UN TAPON INTEGRAL DE COBRE Y BERILO, EL CUAL ESTA APOYADO EN COSTILLAS QUE SE EXTIENDEN RADIALMENTE DESDE LA PARTE AISLANTE PARA OPONERSE A LOS CONTINUOS Y REPETIDOS IMPACTOS DE CARGA SIEMPRE QUE LA PUERTA SE CIERRE.FIG 1.
