パー構造。 In a modeling machine in which main mold sand falling from an aerator is once introduced into a modeling machine hopper through a mortar-shaped upper chute with an on-off valve attached to the lower end opening, and then fed to the modeling machine in batches. , A plurality of nozzle holes are installed at equal intervals in the upper part of the upper chute, and before introducing the main mold sand, air jets are ejected from each nozzle hole at a slight downward slope angle and slightly deflected in the same direction with respect to the center. The main sand hopper structure of the modeling machine is characterized by being designed to inject sand.
