Abstract

The invention provides a sand box having stability. The sand box comprises an upper sand box and a lower sand box, wherein one or more protrusions are arranged at the lower end of the upper sand box; and one or more grooves adapted with the protrusions are formed in the upper end of the lower sand box. According to the sand box disclosed by the invention, the protrusions are arrange on the upper sand box, the grooves are formed in the lower sand box, and the protrusions and the grooves are adapted, so that after being covered, the upper sand box and the lower sand box are closed, the compacting degree of the upper sand box and the lower sand box can be increased; and the situation that during casting, the sand box is deformed caused by that molten iron heat sands in the sand box and are expanded is avoided, so that the quality of a casting is protected.

Description

technical field [0001] The invention relates to the field of foundry tooling, in particular to a stable sand box for sand casting. Background technique [0002] Sand Casting - A casting method in which castings are produced in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. Because the molding materials used in sand casting are cheap and easy to obtain, the casting mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings. It has been the basic process in casting production for a long time. Usually in sand casting, the sand box is an indispensable tool. The sand box is generally made of wood. After a long time of use, it is easy to be damaged, which makes it difficult to align the upper and lower sand boxes, and it is easy to pour out scrap castings. Contents of the invention [0003] Purpose of the invention: The technical problem to be solved by the present...
