置。 After pouring molding sand into a casting flask placed on a model plate with vent holes, compressed air is blown onto the surface of the molding sand to cause the sand to flow through the molding sand toward the model plate to form a green mold. The compressed air blowing device for green molding equipment includes a surface plate-like frame capable of closing the upper end opening of the casting flask and having an exhaust hole facing the upper end opening of the casting flask formed on the upper surface thereof. ;
The cylinder is airtightly attached to the upper surface of the frame, is oriented vertically, and has a cylindrical body whose upper end is closed with a lid, and has an exhaust hole in the lid and an air supply hole in the lower part of the body. a cylinder; a piston fitted in the cylinder so as to be able to slide vertically; and a piston attached to the lower surface of the piston, which closes the exhaust hole of the frame when the piston descends to the vicinity of the air supply hole in the body of the cylinder; a valve that is airtightly mounted on the frame so as to surround the cylinder; and a cover member that together with the frame constitutes a compressed air storage tank; an exhaust pipe extending downward and having a lower end attached to the lid of the cylinder in an airtight manner so as to surround the exhaust hole of the lid; arranged to be movable up and down to open and close the exhaust hole of the cylinder; compressed air in green molding equipment, characterized in that the upper part of the cylinder is connected to a compressed air source through an on-off valve and the inside of the cover member is connected to a compressed air source through a pressure regulating valve; blowing device.
