Technical Field

[0001] The utility model relates to the technical field of casting, in particular to a sand mixer for casting. Background Art

[0002] Casting is a molding method that pours liquid metal into a casting cavity that is adapted to the shape of the part, and after it cools and solidifies, a metal part blank with a certain shape, size and performance is obtained. It is a commonly used metal heat processing process. The sand used for casting can be divided into silica sand and non-silica sand according to its mineral composition. Sand mixing is of great significance in casting. The sand and gravel used for casting often contain multiple ingredients, such as base sand, binder, water and other additives. These ingredients need to be mixed in a certain proportion and stirred evenly through sand mixing equipment to ensure the uniformity and consistency of the sand and gravel.

[0003] At present, when mixing sand, there is no structure to limit and guide the sand mixing tank, and the sand mixing tank cannot rotate smoothly and steadily, resulting in poor practicality. Therefore, a sand mixer for casting is proposed to facilitate the limitation and guidance of the sand mixing tank, so that the sand mixing tank can rotate smoothly and steadily, thereby improving the sand mixing effect.
