It can effectively avoid the problem that manually taking out the sand core from the mold is time-consuming and laborious, resulting in a reduction in the processing efficiency of the subsequent sand core. When the next casting process is required, by making the telescopic end of the electric telescopic rod 17 contract, driving the sliding block 16 to move, and then driving the blower 10 to move, the impurities remaining in the mold can be conveyed to the collection box 12 through the suction hood 15 and the input pipe 14, achieving the purpose of recycling. It can effectively avoid the problem that excessive impurities in the mold lead to a reduction in the casting quality of the sand core and a large amount of resource waste.
