Abstract

See full text

A ventilator for a casting mold is mounted on an exhaust pipe (11) of a mold (10) to emit gas generated when melt is injected into a molding space (12). The ventilator for a casting mold has exhaust holes which are improved in arrangement structure and are shorter than a cylindrical body part so as to enhance gas emission efficiency and prevent transformation of the exhaust holes, and has a buffering space part formed inside a cylindrical body part to spread and accept melt coming through the exhaust holes so as to effectively prevent a damage of a mold caused by external leakage of the melt. The ventilator for the casting mold includes a cylindrical body part (100) and a fixed type exhaust block (20).
