[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it comprises two box bodies buckled up and down, a box belt is provided on the top of the box body, the side wall of the box body is formed by alternately splicing a plurality of inclined box walls and vertical box walls, and sand box exhaust holes are provided in the inclined box walls and the vertical box walls.

[0005] Preferably, the outer side surfaces of the vertical box wall and the inclined box wall are provided with crisscross reinforcing ribs.

[0006] Preferably, a plurality of suspension shafts are provided on two symmetrical vertical box walls.

[0007] Preferably, the bottom edges of two symmetrical vertical box walls are both fixed with a flipping and fastening device, and the flipping and fastening device and the hanging shaft are arranged on different vertical box walls.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model provides a hanging shaft type special sand box with a self-contained fastening device, which uses a cast steel material welding process and has the characteristics of high strength, light weight, durability and the like. The inclined box wall and box belt and other components are manufactured according to certain specifications and sizes, wherein the box wall adopts an inclined splicing structure, which can reduce the amount of molding sand used in mass production, reduce labor intensity, and improve production efficiency. The side wall adds 3 rows of reinforcing ribs in the horizontal and vertical directions to enhance the strength of the sand box; at the same time, a number of exhaust holes are opened on the side of the box wall to facilitate the discharge of gas generated by the sand mold during the pouring process, reducing the risk of suffocation of castings, and 3 φ100 hanging shafts are embedded on both sides of the vertical box wall of the sand box to facilitate the flipping and lifting of the sand box, and a double-arm ear fastening device is used to realize the locking of the upper and lower boxes, which can reduce the lifting time of the iron weight and shorten the turnover time of the sand box.

[0011] Box body 1, box belt 2, inclined box wall 3, vertical box wall 4, reinforcing ribs 5, hanging shaft 6, turning and fastening device 7, sand box exhaust hole 8. DETAILED DESCRIPTION

[0012] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. The preferred embodiments in the description are only used as examples, and all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the utility model.

[0013] like Figure 1 As shown, this specific embodiment adopts the following technical solution: it comprises two box bodies 1 buckled together up and down, a box belt 2 is provided on the top of the box body 1, the side wall of the box body 1 is formed by a plurality of inclined box walls 3 and vertical box walls 4 spliced ​​alternately, and sand box exhaust holes 8 are provided in the inclined box walls 3 and the vertical box walls 4.

[0014] Preferably, the outer side surfaces of the vertical box wall 4 and the inclined box wall 3 are both provided with crisscross reinforcing ribs 5 .

[0015] Preferably, a plurality of suspension shafts 6 are provided on two symmetrical vertical box walls 4 .

[0016] Preferably, the bottom edges of two symmetrical vertical box walls 4 are both fixed with a flipping and fastening device 7 , and the flipping and fastening device 7 and the hanging shaft 6 are arranged on different vertical box walls 4 .

[0017] When the utility model is in use, the two boxes 1 are buckled together up and down, and are flipped and locked by using the flipping and fastening device 7 in conjunction with locking structures such as a pin shaft and a locking ring buckle; during the casting process, the sand mold emits gas and is discharged from the sand box exhaust hole 8, reducing the risk of air suffocation in the casting.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] Using cast steel welding technology, it has the characteristics of high strength, light weight and durability;

[0020] The inclined box wall and box belt are manufactured according to certain specifications and sizes. The box wall adopts an inclined splicing structure, which can reduce the amount of molding sand used in mass production, reduce labor intensity, and improve production efficiency;

[0021] Three rows of reinforcing ribs are added to the side walls to enhance the strength of the sand box;

[0022] At the same time, several exhaust holes are opened on the side of the box wall to facilitate the discharge of gas generated by the sand mold during the pouring process, reducing the risk of air suffocation in the casting;

[0023] Three φ100 lifting shafts are embedded on both sides of the vertical wall of the sand box to facilitate the flipping and lifting of the sand box. A double-arm ear fastening device is used to lock the upper and lower boxes, which can reduce the lifting time of the weights and shorten the turnover time of the sand box.

[0024] For those skilled in the art, they can modify the technical solutions recorded in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
