The invention belongs to the field of non-ferrous metal melting equipment, and relates to an ingot casting device for automatically clearing impurity and finishing appearance. The device comprises a casting part, a baffle plate, a scraper assembly, an edge scraping assembly and an ingot mold, wherein the casting part adjusts the flow by using the dynamic balance principle; the scraper assembly removes oxide layers and impurity; and the edge scraping assembly finishes the ingot casting appearance. The device has the advantages that: because of the adoption of the technical scheme, the device automatically controls the flow and the weight, clears the impurity and finishes the appearance by electric and mechanical automatic control combination; and the device replaces manual operation, improves the dangerous and hard working environment of workers, reduces the labor intensity, improves the work efficiency, has a simple structure, and does not use manual operation.
