六缸油底壳铸件变形原因分析及控制措施

摘要

Aiming at the problem of the deformation of lost foam production six cylinder oil pan,the mold filling, solidification and casting stress of casting were simulated and analyzed with casting simulation software. The main reasons of the casting deformation are pattern deformation because of adding sand and shaking. The process was improved. The experimental results show that the improved technology not only solves the problem of the deformation of the casting, but also improves the production efficiency.%针对消失模生产六缸油底壳铸件变形率较高的问题,采用铸造模拟软件对铸件充型、凝固、应力进行模拟,分析认为造成铸件变形的主要原因是造型过程中加砂和震实造成的.为此对现行工艺提出改进措施.经生产验证,改进工艺不仅解决了铸件变形问题,而且提高了生产效率.
