摘要

铝合金差速器壳体是汽车传动系统的关键部件之一

其结构相对复杂

且内部品质要求较高。生产过程中

需大面积加工

因而暴露出来的内部缺陷大大增加

尤其是夹渣、气孔。为了解决缺陷带来的废品率偏高问题

通过采用数值模拟

将铝合金液充型状态与实际铸件缺陷分布位置进行对比

再对铸件结构进行剖解分析

从而优化浇注系统。通过设计合理的浇注系统从而减少缺陷

降低废品率。

Abstract

Aluminum alloy differential case is one of the key components of automobile transmission system

which has relatively complex structure and high internal quality requirements. In the process of production and manufacture

the product was processed on a large area

taking the internal defects of the product exposed to increase greatly

such as inclusion and gas hole. In order to solve the problem of high reject rate caused by molding defects

the filling process of aluminum alloy was compared with the actual casting defect location by numerical simulation method

and then the product structure was dissected and analyzed to optimize the gating system. It is concluded that more reasonable pouring can improve the risk of process exposure and reduce the reject rate.
