[0002] After the existing castings are ejected from the mold, flash will be generated on the side of the casting. The location of the flash is called the flash position. In order to remove the flash on the flash position of the casting, stamping is used in the prior art. Specifically, during the stamping process, the casting needs to be placed in the stamping die, and then the upper template is driven downward to press the lower template, so that the stamping part on the upper template is pressed against the flash on the casting, thereby removing the flash on the casting. Since the current stamping die can only remove the flash on a single side of the casting, if the flash on multiple sides of the casting needs to be removed, it is necessary to stamp multiple times, and each time the stamping needs to adjust the stamping part on the stamping die or replace the stamping part of a different shape, which makes the flash removal process complicated and seriously affects the flash removal efficiency of the casting.
