パーの構造。 A blow head 17 that carries molding sand and performs reciprocating motion between stop positions A and B provided inside the machine body 14, and a core molding mechanism below the stop position B that transports the mold sand in the blow head 17. A core molding machine 20 having an air cylinder 18 that blows out compressed air for pressurizing the inside of the core molding machine 19, and a core molding mechanism 19 disposed below the stop position B.
Inside the hopper 1 disposed above the stop position A, there is a circular section 5 which serves as the rotation radius of the two groups of feed blades, and a trapezoidal section connected to the upper part of the circular section 5 and having a substantially trapezoidal cross section. By providing the cross-sectional portions 6 extending in the direction of transport of the molding sand,
The structure of a hopper dedicated to a core molding machine is characterized by providing a transfer region 7 with a circular cross section and a crosslinking prevention region 8 with a trapezoidal cross section.
