Die-casting forming process of gearbox clutch shell

Abstract

The invention relates to a die-casting forming process of a gearbox clutch shell. The limitation that a traditional die-casting process depends on actual production experience and a repeated trial-and-error method to improve the quality of a gearbox clutch shell is improved; CAE simulation is conducted on the gearbox clutch shell die-casting process through ProCAST software, die-casting technological parameters under the condition that defects such as shrinkage porosity and shrinkage cavity are minimum are obtained, and a needed die-casting die is analyzed, judged and formulated; and meanwhile, the die-casting die of the gearbox clutch shell is provided with the corresponding exhaust grooves and the multiple ejection mechanisms, air in the die-casting die can be exhausted in time in the mold filling process, and thus the defects of insufficient pouring, air pores and the like are avoided.

Description

technical field [0001] The invention relates to the field of die-casting technology, in particular to a die-casting molding technology for a gearbox clutch housing. Background technique [0002] At present, the gearbox clutch housing is a relatively complex product. In order to reduce the defects such as shrinkage and shrinkage of the gearbox clutch housing during the molding process, there are two main methods: one is to modify the pouring in the original die-casting mold. System and overflow system and other structures; the second is to adjust the corresponding die-casting process parameters. Although the first method is effective, but the internal structure of the design mold changes, the time cost and mold cost are high, while the second method only involves the adjustment of parameters such as mold temperature, injection speed and pouring temperature, which is very convenient. But now there is no systematic die-casting process to quickly obtain the above parameters. ...
