Steel balls and cast balls made by vertical centrifugal casting machines are commonly used according to the different spatial positions of the mold's rotating axis. In the prior art, it is still difficult to achieve automated production in the field of casting machines, especially in the casting process, where workers have always been responsible for quantitatively adding aluminum liquid to the casting machine. Therefore, employees are required to be experienced and have comprehensive skills. At the same time, the physical exertion of employees is too great, the labor efficiency is low, and insufficient casting volume is prone to occur. After additional casting, interlayers appear with the original casting, affecting the quality of the product.
