Abstract

Dispositivo para la fabricación de un cuerpo moldeado de material sintético, en el que se introduce material sintético calentado hasta hacerlo plastificable en una cavidad de moldeo y es prensado allí para obtener el cuerpo moldeado, cuyo dispositivo comprende un cuerpo giratorio accionable paso a paso, que lleva matrices y machos de útiles de mecanización en posiciones distribuídas en dirección periférica a distancias uniformes una de otra, estando dispuesta en cada caso una matriz y un macho asociado en una posición coaxial de manera que pueden ser aproximados uno con relación a otro y retraídos separándose uno de otro, así como también hechos bascular saliendo de la posición coaxial, caracterizado porque los útiles de prensar, de los cuales las matrices están dispuestas sobre el cuerpo giratorio, configurado en forma de mesa giratoria, con su lado abierto dirigido hacia arriba, porque los machos están dispuestos de manera que pueden ser hechos bascular saliendo de la posición coaxial conlas matrices correspondientes para dejar libre el espacio situado por encima de la matriz, y porque ele elemento de entrega de material está dispuesto con su abertura de salida directamente por encima de la matriz en una posición de etapa en la que el macho asociado está basculado hacia afuera de la posición coaxial.
