Abstract

Se describe un sistema de moldeo de preforma que incluye una media cavidad que puede montarse en una platina fija de una máquina de moldeo de inyección y una media alma que puede montarse en una platina de movimiento de la máquina de moldeo de inyección. El sistema de moldeo de preforma incluye un montaje de pisos de molde (también llamado sándwich de moldes) que tiene una porción de cavidad y una porción de alma. La porción de cavidad está acoplada con la media cavidad e incluye un inserto de cavidad y la porción de alma está acoplada con la media alma e incluye un inserto de alma, un par de anillos de cuello y un anillo desmoldador o separación de molde. El inserto de alma tiene un corte sesgado que define una protuberancia anular en una superficie interna de la preforma que es creada en el montaje de pisos de molde. El sistema de moldeo de preforma se configura para permitir en secuencia, la retracción del par de anillos de cuello fuera del inserto de alma y la eyección de la preforma del inserto de alma por medio del anillo desmoldador.
