[0002] The foundry industry is an important field in the manufacturing industry. Casting is the process of injecting molten metal or other materials into a mold to solidify it into a shape, thereby manufacturing various parts, components and products. These products can be used in multiple fields such as automobiles, aerospace, construction, and mechanical equipment.

[0003] In the foundry industry, sand falling and sand dropping are likely to occur in the mold cavity during molding and core setting due to unreasonable mold design, poor quality of sand cores or sand mold materials, and improper pouring process. In particular, manual cleaning of sand falling in the mold cavity of some large and medium-sized castings is very troublesome.

[0004] The existing method is to use a plastic hose to blow out the sand, but this method has a low cleaning efficiency and often blows the sand to a place that is not easy to find, causing sand to fall out of the casting and resulting in the scrapping of the casting. Therefore, a new type of sand suction tube is proposed to solve the above problem. Utility Model Content
