The present invention relates to a die-casting gas removing device capable of preventing fine dust or the like from adhering to a sliding portion of a closing valve so that operation of the gas removing device can be smoothly performed over a long period of time, productivity is improved, And a method for preventing malfunction of the opening / closing valve.
SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-described problems, and it is an object of the present invention to provide a vacuum degassing apparatus for a vacuum degassing apparatus, Is low and the temperature of the molten metal containing fine dust passes through the main passage is high and reaches the closing valve later than the good quality molten metal to prevent the malfunction of the opening / closing valve. It is also preferable that the main path be provided with a bending portion, and the bypass path is provided across the movable block and the fixed block. Alternatively, the bypass path may be a closed path. In the present invention, the term "closed path" refers to a path where the molten metal solidifies and becomes a pouring basin.
