[0002] The impeller, also known as the working wheel, is an important part of the gearbox. When processing and producing the gearbox, a casting mold is required to cast the impeller. The casting mold can be used to shape the metal liquid so that the metal liquid reaches the specified processing specifications after solidification.

[0003] A casting mold is needed when processing and producing a gearbox. Among them, the "casting mold for a gearbox impeller" disclosed in the publication number "CN217647466U" has solved the various disadvantages that the cast gearbox will get stuck on the mold, making it difficult for the staff to easily remove the gearbox from the mold.

[0004] However, there are still many defects in the actual use of impeller processing equipment with similar structures, such as: it does not have the function of automatically demolding the impeller, and the operator needs to use external auxiliary equipment to demold the impeller, which increases the workload of the operator and complicates the process of casting impellers using the device. At the same time, it does not have the function of improving the quality of the cast impeller, resulting in impurities remaining in the mold that easily affect the processing of the next batch of impellers, and the quality control of the impeller cast using the mold cannot be guaranteed. Therefore, it is necessary to design a casting mold for the gearbox impeller. Utility Model Content
