Abstract

EN EL DISPOSITIVO DE CIERRE DE MOLDE PARA UNA MAQUINA DE MOLDEO DE INYECCION, EN EL MOLDE FIJO (1) INMOVIL (4) SE DISPONE DE HUSILLOS (36) DE MOVIMIENTO QUE PUEDEN GIRAR LIBREMENTE EN LA SUJECION (1) DEL MOLDE FIJO, ESTAN SOPORTADOS AXIALMENTE EN UNA DIRECCION Y APOYADOS EN LAS TUERCAS (39) DE HUSILLO ASEGURADAS EN LA SUJECION (4) DE MOLDE MOVIL. PARA LA ACTUACION DE LOS HUSILLOS (36) DE MOVIMIENTO PARA CIERRE Y APERTURA DE LOS MOLDES (4) MOVILES SE DISPONE DE UN ACCIONAMIENTO (44) ROTATIVO Y UNA UNIDAD (45,46) EMBOLO-CILINDRO HIDRAULICA EN CONEXION OPERATIVA CON LOS HUSILLOS DE MOVIMIENTO PARA LA ACUMULACION DE LAS FUERZAS DE CIERRE. PARA ASEGURAR QUE, MIENTRAS SE MANTIENE UNA ALTA PRESION DE CIERRE EJERCIDA POR LA UNIDAD EMBOLO-CILINDRO HIDRAULICA, EL ACCIONAMIENTO DE ACTUACION DEL HUSILLO DE MOVIMIENTO DEBE SER DISEÑADO SOLO DE ACUERDO CON LOS REQUERIMIENTOS PARA APERTURA RAPIDA Y MOVIMIENTOS DE CIERRE, SE PROPONE QUE LA UNIDAD EMBOLO-CILINDRO HIDRAULICA CONSISTA EN UNO O MULTIPLES EMBOLOS Y CILINDROS HIDRAULICOS, A LOS QUE SE APLICA EL AGENTE PRESURIZADO, PARA ACUMULACION DE LA PRESION DE CIERRE, MEDIANTE LA UNIDAD EMBOLO-CILINDRO DERIVABLE A TRAVES DE LOS HUSILLOS DE MOVIMIENTO CON LA INSERCION DE DISPOSITIVOS (19) DE TRASMISION DE PRESION.
