Abstract

Un aparato para moldear un cierre de material plástico, que incluye un conjunto de molde macho que incorpora un vástago formador y un manguito de vástago exterior, que coopera con un molde hembra para definir una cavidad de molde. Para facilitar el desprendimiento mecánico del cierre moldeado del vástago formador, se introduce aire presurizado dentro del cierre moldeado a través de por lo menos una vía de paso de aire, que se extiende en sentido axial entre el vástago formador y el manguito del vástago. Expandiendo hacia fuera y formando el cierre de material plástico durante la eyección desde el vástago formador, se reducen significativamente las fuerzas a las que se ve sometido el cierre durante la eyección, reduciendo así de manera conveniente la intensidad de enfriamiento del cierre, requerida durante el ciclo de moldeado anterior a la eyección. Pueden lograrse así velocidades operativas significativamente mayores para el aparato de moldeado por compresión.
