Abstract

PROCEDIMIENTO Y DISPOSITIVO CORRESPONDIENTE PARA EL MOLDEO POR INYECCION. EL DISPOSITIVO CONSTA DE UN MOLDE (12) DE TEMPERATURA CONTROLADA Y UN MANDRIL INTERNO (14), QUEDANDO DEFINIDA ENTRE ESTE Y LA SUPERFICIE INTERNA DEL MOLDE LA FORMA DEL ELEMENTO REPETIDO DEL ARTICULO DE PLASTICO (40) A FABRICAR. EL MANDRIL INTERNO (14) ES SOLIDARIO DE UN MANDRIL EXTERNO (20) DE LA MISMA SECCION TRANSVERSAL, PERO SEPARADO DE ESTE MEDIANTE UNA PLACA DE AISLAMIENTO TERMICO (22). EL MATERIAL PLASTICO SE INYECTA EN LA CAVIDAD FORMADA POR EL MOLDE (12), EL MANDRIL INTERNO (14), Y UNAS PUERTAS DE CIERRE (18, 18.1) DE LA CAVIDAD; DESPUES DE UN PERIODO DE ENFRIAMIENTO EL MANDRIL INTERNO SE MUEVE HACIA LA DERECHA Y EL PRIMER ELEMENTO DE PLASTICO FORMADO SE SITUA SOBRE EL MANDRIL EXTERNO (20), A CONTINUACION SE ABREN LAS PUERTAS DE CIERRE (18, 18.1) Y SE ACCIONAN LOS MANDRILES HACIA LA IZQUIERDA, QUEDANDO FORMADA OTRA CAVIDAD, AHORA CERRADA POR EL ELEMENTO DE PLASTICO FABRICADO; SE VUELVE A INYECTAR MATERIAL PLASTICO FORMANDOSE UN NUEVO ELEMENTO QUE SE SUELDA AL PRIMERO.
