Abstract

UN METODO DE MOLDEO POR INYECCION SEGUN EL CUAL EL MATERIAL DE PLASTICO SE PLASTIFICA POR HUSILLO Y ES INYECTADO A TRAVES DE UN PISTON Y EL MATERIAL DE PLASTICO PLASTIFICADO SE ALIMENTA EN EL CILINDRO DE INYECCION POR PISTON (18) DURANTE EL RETORNO DEL PISTON DE INYECCION (19). EL HUSILLO PLASTIFICANTE (12) ROTA DE FORMA CONTINUA EN UNA POSICION AXIAL FIJA DEL CILINDRO PLASTIFICANTE (10), QUEDANDO EL MATERIAL DE PLASTICO A PRESION ALMACENADO TEMPORALMENTE EN UN ESPACIO A PRESION (26) DURANTE LA CARRERA OPERATIVA DEL PISTON DE INYECCION PARA SER ALIMENTADO DURANTE EL RETORNO DEL PISTON DE INYECCION DESDE DICHO ESPACIO HASTA EL CILINDRO DE INYECCION JUNTO CON EL MATERIAL DE PLASTICO PLASTIFICADO SUMINISTRADO DIRECTAMENTE DESDE EL HUSILLO PLASTIFICANTE (12) HASTA EL CILINDRO DE INYECCION. UNA MAQUINA DE MOLDEO POR INYECCION PARA LLEVAR A CABO EL METODO CONSISTE EN UN CILINDRO DE PLASTIFICACION POR HUSILLO (10) Y UN CILINDRO DE INYECCION POR PISTON (18) CONECTADO AL ORIFICIO DE SALIDA DEL CILINDRO DE PLASTIFICACION POR HUSILLO A TRAVES DE UNA VALVULA DE RETENCION. HAY UN CILINDRO DE CARGA (26) QUE TIENE UN PISTON A PRESION (27) CONECTADO DIRECTAMENTE AL ORIFICIO DE SALIDA DEL CILINDRO DE PLASTIFICACION, QUEDANDO TAMBIEN DICHO CILINDRO DE CARGA CONECTADO AL CILINDRO DE INYECCION POR PISTON A TRAVES DE LA VALVULA DE RETENCION.
