A flow hole through which core sand is poured into the cavity is formed, and a through hole through which an ejector pin for pushing out the core sand in the cavity is inserted is formed on the other side of the upper mold or the lower mold. In a core forming mold device equipped with an air vent that releases air inside the cavity to the outside through a vent plug attached to one end of the wall, an air supply and exhaust path is formed inside the upper plate. The air vent is communicated with the air supply/exhaust passage, and an air blowing device is disposed outside the air supply/exhaust passage to supply compressed air to the vent plug via the air supply/exhaust passage at an appropriate time. A mold device for forming cores.
