Abstract

Se proporciona un dispositivo de desgasificación de molde que puede reducir la probabilidad de que entren partículas entre un vástago de válvula y un agujero de inserción. El dispositivo de desgasificación de molde (10, 40, 50) incluye un pasaje de entrada (11, 41, 51), un pasaje de descarga (12), un pasaje de comunicación (13), un dispositivo de válvula (30) para abrir y cerrar el pasaje de comunicación (13), una parte de ajuste de flujo de gas para ajustar un flujo de gas. Una superficie de pared que forma el pasaje de comunicación (13) se proporciona con un agujero de inserción (32d) a través del cual se inserta un vástago de válvula (31) del dispositivo de válvula (30). La parte de ajuste de flujo de gas se coloca más cerca del pasaje de entrada (11, 41, 51) que del agujero de inserción (32d) y, cuando se descarga gas, genera un flujo de gas dirigido de manera rotacional sobre un eje (C).
