Abstract

La invención se refiere a un manguito dinámico distribuidor de material plástico fundido, de tipo articulado, destinado a compensar las diferencias de dilatación en el canal caliente de circulación interna aislada por ranuras de ventilación, en moldes de inyección para transformar los materiales plásticos. Los manguitos de este tipo, anclados fijamente, reivindicados hasta ahora, presentaban tolerancias de montaje extremadamente apretadas y conllevaban a menudo una ruptura de la cavidad del molde o fugas debidas a diferencias de dilatación. El manguito descrito en la presente invención, comprende labios de estanqueidad periféricos en sus dos extremos y está montado entre el canal caliente (3) y la cavidad del molde (6), éste compensa el fenómeno de dilatación térmica y permite, gracias a una estanqueización de la ranura de ventilación (4) una separación térmica más nítida en la región de la entrada del molde de inyección.
