Sand casting is a common casting method, a sand mold is generally required in a molding process, and particularly, a production line is adopted to carry out an operation process, and a specific sand box is often required to be manufactured according to specific products. The sand box mainly has the functions of fixing the sand mould, facilitating demoulding in the moulding process, facilitating sand mould transfer and locking the sand mould in the mould assembling process. The rib plates in the sand box mainly play a role in preventing the sand mould from sinking or deforming.
In the design and manufacturing process of the traditional sand box, the overall dimension and the rib plate structure of the sand box, namely a special sand box, are often required to be designed according to the dimension of a casting product and a casting process so as to realize the optimal combination of manufacturability and sand consumption. However, a special sand box is designed for each product, and a large number of sand boxes are required to be manufactured along with the increase of product varieties. The storage, custody and use of these flasks require a significant amount of resources. When a special sand box is used for producing other castings, the height and the inner diameter are not matched, or the sand consumption of the castings is too large, and the molding sand, the curing agent and the bonding agent are wasted; or the flask needs to be cut (rib plates interfere with the mold or the sprue) to accommodate new castings, which damages the flask and reduces the service life of the flask. Particularly, when the height of the sand box is not enough, a layer of upper sand box must be stacked on the lower sand box, so that the machine can not be used for overturning and stripping, the machine can only be used for overturning and stripping manually, and if the machine is used for stripping, the sand box must be manufactured again.
