Description

Technical Field

[0001] The utility model relates to the technical field of forming dies for producing a casing of an electric vehicle reducer, in particular to a forming die for a casing of an electric vehicle reducer. Background Art

[0002] As we all know, most industrial products nowadays need to use molds to unify product specifications. The reducer of electric vehicles is one of the common structures in the transmission system of mechanical equipment. It has relatively high requirements for precision and quality. Naturally, molds are also needed when manufacturing its shell. When the mold is separated and the casting is taken out, the demolding mechanism set in the mold base needs to operate to perform demolding operations. However, under high quality requirements, the demolding mechanism often has large operating accuracy errors after long-term use due to mechanical fatigue and other factors, resulting in an increase in the number of scratches and bumps on the reducer shell workpieces. Personnel are also required to frequently maintain the demolding mechanism to ensure the yield rate of the reducer shell workpiece production. The traditional mechanical demolding mechanism requires personnel to perform regular inspection and maintenance, which greatly increases the workload of personnel. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content
