Description

Technical Field

[0001] The utility model relates to the technical field of processing of casting moulding sand, in particular to a casting moulding sand stirring machine. Background Art

[0002] Sand casting refers to a casting method for producing castings in sand molds. Steel, iron, and most non-ferrous alloy castings can be obtained by sand casting. Since the molding materials used in sand casting are inexpensive and easy to obtain, and the manufacture of sand molds is simple, it can adapt to single-piece production, batch production, and mass production of castings.

[0003] During the production and processing of sand casting, a stirring device is used to stir the raw materials for sand casting. A stirring rod is arranged in the stirring device, and the sand casting is mixed by the rotation of the stirring rod. At present, most of the stirring devices are open barrel-shaped structures, which leads to the sand casting being in an external state during stirring. In this external state, a large amount of dust will be raised during the stirring of the sand casting, which not only affects the surrounding environment but also fails to guarantee the safety of the operator during operation. Also, since the sand casting can only be stirred once in the stirring device, there are certain limitations in the stirring effect in the stirring device, which prolongs the stirring time of the sand casting and thus affects the efficiency of sand casting stirring.
