PROBLEM TO BE SOLVED: To fully perform a gas releasing function, a function for releasing a mold of a molding article, and a function for preventing clogging of a passage for gas releasing and the like, even when a thin molding article is cast. SOLUTION: This device is equipped with an upper movable die 7 and a lower fixed die 8 for forming a cavity 9, ejector pins 12 protruding to the cavity side in a rising process of the movable die 7, and gas releasing pins 13 which have grooves 16 for forming a gas releasing passage on a periphery and protrude after protrusion of the ejector pins 12. In this case, when a thin molding article is cast, each of the pins 12 and 13 is arranged at an optimum portion, so as to secure a function for releasing gas, a function for releasing a mold of the molding article, and a function for preventing clogging of the gas releasing passage and the like. |
