Abstract

SE PRESENTA UNA BOQUILLA DE MOLDEADO A INYECCION (14) PARA UN MATERIAL DE MOLDEADO TERMOENDURECIBLE DE MOLDEADO EN CORREDERA FRIA EN UN MOLDE CALIENTE. UN ORIFICIO (48) SE EXTIENDE CENTRALMENTE A TRAVES DE LA BOQUILLA (14) PARA DIRIGIR EL MATERIAL DE MOLDEADO LIQUIDO DESDE UN DISTRIBUIDOR ENFRIADO (10) HASTA UNA COMPUERTA (42) QUE SE DIRIGE A UNA CAVIDAD (44). UN CONDUCTO DE FLUIDO DE ENFRIAMIENTO, INTEGRAL (82) TIENE UNA PARTE HELICOIDAL (88) QUE SE EXTIENDEN CONCENTRICAMENTE ALREDEDOR DEL ORIFICO DEL MATERIAL DE MOLDEADO (48). EL FLUIDO DE ENFRIAMIENTO CIRCULA DESDE UNA PARTE DE ENTRADA RADIAL (84) HASTA UNA PARTE DE SALIDA RADIAL (86) DEL CONDUCTO DE FLUIDO DE ENFRIAMIENTO (82) PARA ENFRIAR EL MATERIAL DE MOLDEADO LIQUIDO QUE FLUYE A TRAVES DEL ORIFICIO CENTRAL (48).
