Abstract
Se describe un método y un aparato para el moldeo por compresion de artículos de plástico, incluyendo cierres, el cual incluye la provision de grupos de coaccion de herramientas que incluyen un primer grupo para el movimiento de un nucleo y de una manga de nucleo, en acoplamiento con un molde de cavidad sobre un segundo grupo herramental. Se proporciona un accionador entre el primer grupo de herramientas y una leva superior fija. El segundo grupo de herramientas incluye un accionador que soporta el molde de cavidad, y asociado con una leva inferior fija. Un cilindro de nitrogeno en el segundo grupo de herramientas proporciona el control de la fuerza de moldeo por compresion. En una forma preferida, se proporciona una pluralidad de grupos de herramientas en relacion circunferencialmente espaciada, sobre una torreta giratoria soportada por una columna central. Una tubería comun suministra la presion, a presion controlada de manera precisa, a cada uno de los cilindros de nitrogeno. Se proporciona un sistema de control para la verificacion periodica y el cambio de presion.
