Abstract

SE DESCRIBE UN MACHO O NUCLEO REPLEGABLE PARA UN MOLDE, QUE COMPRENDE TRES CONJUNTOS (10, 110, 210) MOVIBLES RELATIVAMENTE. EL PRIMER CONJUNTO LLEVA UN CONO (14), EL SEGUNDO CONJUNTO LLEVA UN JUEGO DE SEGMENTOS (116) QUE FORMA PARTE DE LA SUPERFICIE DEL NUCLEO Y SE ACOPLA AL CONO (14), Y EL TERCER CONJUNTO (210) LLEVA LOS SEGMENTOS EXTERIORES (216) MOVIDOS MEDIANTE ESPIGAS INCLINADAS (116) EXISTENTES EN EL SEGUNDO CONJUNTO. CUANDO LOS CONJUNTOS SE MUEVEN UNO HACIA OTRO, LOS SEGMENTOS EXTERIORES (216) SE MUEVEN RADIALMENTE HACIA FUERA Y LOS SEGMENTOS INTERIORES (116) SE MUEVEN AXIALMENTE ENTRE ELLOS. ENTONCES LOS SEGMENTOS INTERIORES SE MUEVEN RADIALMENTE HACIA FUERA Y EL CONO LLENA EL CENTRO DEL NUCLEO. INVIRTIENDO EL MOVIMIENTO, EL NUCLEO ES REPLEGADO PARA PERMITIR EXTRAERLE DEL ARTICULO MOLDEADO.
