汽车凸轮轴支架铝合金零件的压铸成形在技术开发中存在一定的难度。针对某汽车凸轮轴支架铝合金的压铸成形,应用数值模拟,通过了解铝液流动充型状态与铸件缺陷的分布,确定了铸件的浇注系统与排气系统,大大缩短了模具的开发周期。同时在试模与试生产阶段,从浇注、工艺、模具等方面分析了不同缺陷产生的原因,并且提出了改善措施。结果表明,合理的浇注、排气系统与合理的冷却是获得高品质压铸件的关键。
Automotive camshaft support aluminum alloy die-casting parts in the development of technology there is a certain degree of difficulty. Aiming at the die casting of aluminum alloy camshaft bracket, the application of numerical simulation is adopted to understand the distribution of molten aluminum filling flow and casting defects and to determine the pouring system and exhaust system of casting, which greatly shortens the development cycle of the mold. At the same time in the trial and trial production stage, from the casting, technology, mold and other aspects of the analysis of the causes of different defects, and put forward improvements. The results show that reasonable casting, exhaust system and reasonable cooling is the key to obtain high quality die-casting.
