Description

Automatic cleaning device for accumulated sand in sand tire exhaust hole Technical Field The invention relates to the technical field of casting sand tires, in particular to an automatic cleaning device for accumulated sand in a sand tire exhaust hole. Background In the sand casting industry, exhaust holes are drilled in a mold body after sand molding, so that air stored in the sand mold in the casting process is smoothly discharged, and the quality of castings is prevented from being influenced. However, after the sand mould is drilled with the vent holes, residual sand can remain in the holes, and the residual sand is mixed into the cast to produce some bad or scrapped products, so that the production benefits of enterprises and the quality of the cast are seriously affected. However, the existing automatic cleaning device for the sand accumulation in the sand tire exhaust hole has the following problems that the sand accumulation in the traditional casting sand tire exhaust hole is finished by manual operation, because the sand box is large in size, the manual operation is inconvenient, waste time and labor are wasted, the blow-out phenomenon is easy to occur, and the product quality is influenced.
