Abstract

Perfeccionamientos en los moldes para la fabricación de objetos conformados con material plástico por calentamiento por alta frecuencia, caracterizados por comprender; a) una parte inferior constituida por una estructura metálica que tiene por lo menos un emplazamiento que representa en hueco la configuración general de un objeto que hay que reproducir y que contiene en el interior. - en la zona que rodea dicho emplazamiento: una primera capa relativamente espesa de material plástico con pequeñas pérdidas dieléctricas, cargado por lo menos con el 80% de polvo metálico y luego una segunda capa delgada de dicho material plástico puro exento de carga; - en el exterior de dicha zona y llenando todo el volumen restante disponible, un material aislante para la alta frecuencia; - en el fondo de dicho emplazamiento, la mitad inferior de la maqueta o contramolde del objeto a moldear; b) una parte superior constituida por una placa metálica que comprende la mitad superior de la maqueta o contramoldedel objeto a moldear consistente en dicho material plástico con por lo menos el 20% de carga metálica; dicha parte superior, después de insertar el material destinado a la fabricación del objeto que hay que moldear en los intersticios y huecos de dicha mitad inferior de maqueta, es posicionada mediante espigas sobre la parte inferior del molde y se somete luego a la acción de la corriente de alta frecuencia.
