A kind of exhaust apparatus for hot box, including hot box；Core cavity is equipped in hot box, hot box divides on groove face
Equipped with air discharge duct, one end of air discharge duct is connected to core cavity, and the other end of air discharge duct is pierced by the box body of hot box；Air discharge duct is equipped with
Horizontally movable venting plug, venting plug include chock plug and cock body, and cock body is equipped with first row stomata, second row stomata and third
Gas vent is equipped with sieve in first row stomata, second row stomata and third gas vent.
Further, there are three types of mesh sizes, the sieve of three kinds of mesh sizes to be respectively provided at first row stomata, second for sieve
In gas vent and third gas vent.
By the way that the sieve of three kinds of mesh sizes is arranged, the core sand of unlike material can be prevented to occur running sand phenomenon.
Further, venting plug is threadedly coupled with hot box.
Different gas vents can be switched by twisting venting plug.
Further, the depth of air discharge duct is 0.1mm-0.4mm.
Further, chock plug is interior five corner bolts head.
Further, the cross-sectional area of first row stomata, second row stomata and third gas vent is equal to vent
Cross-sectional area.
Guarantee that the gas of hot box discharge can pass through gas vent and enter in vent.
Compared with the existing technology, a kind of exhaust apparatus for hot box described in the utility model has the advantage that
A kind of exhaust apparatus for hot box described in the utility model is used cooperatively air discharge duct and two kinds of venting plug
Method combines, and solves the problems, such as that the sieve in gas vent can prevent core because sand core shape can not open up exhaust apparatus
The problem of sand is run out of, and the exhaust apparatus is located on point groove face, can be handled in time core sand blocking.
