A die-casting process for a gearbox clutch housing

Abstract

The invention relates to a die-casting forming process of a gearbox clutch housing, which improves the limitation of the traditional die-casting process of relying on actual production experience and repeated trial and error to improve the quality of the gearbox clutch housing. CAE simulation of the die-casting process is carried out to obtain the die-casting process parameters with minimal defects such as shrinkage porosity and shrinkage holes, and analyze and determine the required die-casting molds; at the same time, the die-casting molds of the gearbox clutch housing are provided with corresponding exhaust slots, and There are multiple ejection mechanisms, which is conducive to the timely discharge of the air inside the die-casting mold during the filling process, thereby avoiding the occurrence of defects such as insufficient pouring and pores.

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. ...
