摘　　要：为提高DISA线球铁薄壁管件的生产效率,提高产品质量,以三通管为例,重新对管件模具进行优化设计,阐述了DISA垂直造型线薄壁管件的模具布局及铸造浇注系统的设计方法。结果表明,按照新的工艺试验浇注铸件,优化的三通管件生产效率提高了100%。铸件内部无缩松、缩孔缺陷,废品率控制在2%以下,成功实现了该薄壁管件的大批量机械化生产。In order to improve the production efficiency and product quality of ductile iron thin-wall pipe fitting with DISA line,taking tee pipe as an example,the mould design of thin-wall pipe fitting with DISA vertical modeling line was optimized again,and the mould layout and the design method of casting system were expounded.The results show that the production efficiency of the optimized tees increases by 100%according to the new process test.There is no shrinkage cavity or porosity defects in the casting,and the rejection rate is controlled below 2%,which has successfully realized the large-scale mechanized production of the thin-walled pipe fitting.
