[0002] Sand boxes play a crucial role in industrial manufacturing, especially in the foundry industry. Their primary function is to serve as containers for molding sand during casting, ensuring that the sand forms the desired casting shape. Sand boxes are typically made of metal, and their design must consider strength and durability to withstand the pressure of the molding sand solidifying and the metal melting during casting. Furthermore, the design of sand boxes also involves dimensions, shape, and ease of handling. Removing the molded parts from the sand box generally requires the use of a sand box tilting machine to empty it.

[0003] Currently, some sand box turning machines on the market are indeed designed in a conservative and standardized manner, mainly in terms of mechanical structure, power configuration, and control system. These designs are often optimized based on specific sand box sizes and weight ranges, but fail to fully anticipate or reserve sufficient adjustment space to cope with diverse production needs.
