Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution:

the utility model provides a sand box for producing stock class foundry goods, include and pile up the sand box that the concatenation formed by cope flask 1 and drag flask 2, cope flask 1 and drag flask 2 are made by

structure frame

5, 5 both ends of structure frame all are provided with end plate 6, the equidistance is provided with the case fender 7 that the array is parallel with end plate 6 in the structure frame 5, all be provided with foundry goods shape breach 8 on case fender 7 and on the end plate 6 of 5 one sides of structure frame or both sides, 6 both ends of end plate of cope flask 1 and drag flask 2 all are provided with connecting hole 4, pass through 4 fixed connection of connecting hole through connecting bolt between the sand box.

Wherein, the top of the cope flask 1 and the bottom of the drag flask 2 are both provided with a structural plate 3.

Wherein, a technical opening 10 is arranged on the rear side plate of the structure frame 5 of the drag flask 2, and a side baffle 11 is arranged outside the rear side plate of the structure frame 5.

Wherein, the outer side of the end plate 6 at one side or two sides of the structure frame 5 is fixedly provided with an end baffle 9.
