汽车铝合金支架零件压铸工艺优化设计

Optimization Design of Die Casting Process for Automotive Alloy Support Frame

针对汽车发动机铝合金燃油滤清器支架实际压铸生产中缺陷较多、打压检测合格率低的问题,采用Pro CAST数值模拟软件对压铸工艺过程进行模拟、对缩孔缩松缺陷进行预测。根据模拟结果,确定合理浇注方案,采用正交试验确定最佳工艺参数。结果表明,燃油滤清器支架最佳压铸工艺参数为:模具预热温度200℃,压射速度1 m/s,浇注温度630℃,应用设计方案及最优工艺参数,完成铸件的压铸生产,得到的铸件质量良好,通过压力检测,效果理想。

Aiming at the problem of low defects rate in automobile engine aluminum alloy fuel filter support frame die-casting production and lower qualified rate. The ProCAST numerical simulation software is used to predict the process of die casting and shrinkage defects, according to the simulation results, determine the reasonable casting solution, using orthogonal test to determine the best process parameters. The results show that the fuel filter support frame best die casting technology parameters is for mold preheat temperature 200 ℃, injection speed 1 m/s, pouring temperature 630 ℃, application design and the optimal process parameters, complete casting die casting production and processing, get the casting quality is good, the effect is ideal through pressure test.
