[Claims for Utility Model Registration] An upper mold and a lower mold forming a cavity of a predetermined shape inside, an air vent attached to one end of the cavity, and an ejector bar disposed above the upper mold. A low-pressure casting device comprising: an ejector plate that is pushed by the ejector plate; and an ejector pin that is protruded from the ejector plate and that pushes out the casting in the cavity through a through hole formed in the upper die. , the ejector plate is divided into a first ejector plate on which an ejector pin for ejecting a product is protruded, and a second ejector plate on which an ejector pin for air vent is protruded; Therefore, the low pressure casting apparatus is characterized by comprising a delay means for pushing the second ejector plate after the first ejector plate is pushed.
