Abstract

Un mecanismo de compuerta de valvula para el uso con sistemas de moldeo por inyeccion de plastico asistidos por gas. Un mecanismo de pasador movible se coloca en un buje o boquilla de la maquina para regular la inyeccion del material de plastico en una cavidad de moldeo. El mecanismo de pasador tiene una cola de milano externa y una cola de milano interna. El movimiento de la cola de milano interna con relacion a la cola de milano externa permite que el gas se inyecte en el plastico en la cavidad de moldeo. Un miembro de muelle, tal como una arandela Belleville, alterna la cola de milano interna a la posicion cerrada con relacion a la cola de milano externa. La presion de gas desde la fuente de gas supera la fuerza del miembro de muelle que permite que el gas entre en la cavidad de moldeo.
