Technical Field

[0001] This utility model relates to the field of casting production technology, and more specifically, to a casting cleaning device and a casting production line. Background Technology

[0002] Castings, as an important industrial product, are widely used in various fields. However, during the production process, especially after casting, cooling, and grinding, impurities such as oil, residual sand, and oxides often adhere to the surface and internal cavities of castings. These impurities not only affect the appearance quality of the castings but can also seriously impact their performance and service life. Therefore, thorough cleaning of castings has become an indispensable part of the casting production process.

[0003] For some castings without internal cavities, it is often only necessary to clean the surface of the casting. Spray cleaning is usually used. However, most existing spray cleaning devices have certain defects. If a large number of nozzles are arranged, the spray cleaning effect is better, but it consumes more cleaning fluid.
