摘要
介绍了一种汽车用球墨铸铁换挡拨叉的铸造工艺方法。该工艺是在原来一型只能水平布置2个铸件的前提下,在不改变造型设备的基础上,通过采用垂直放置和每个铸件仅使用一个冒口的方法将一型布置为3件,设计了满足质量要求的铸造工艺方法。经模拟分析和实践验证,生产出的铸件均能符合客户指定标准的所有要求,目前,已具备投入批量生产的条件。
This paper introduced a casting process of ductile iron gearshift fork for vehicle.This process is based on the premise that only two castings can be placed in one mold,and the mold is arranged into three pieces by using the method of vertical placement and single feeder for each casting without changing the molding equipment.And a casting process is designed to meet the requirements of customers,through simulation analysis and practice verification,the castings meet all the requirements of customer specified standards.Currently,the conditions for mass production have been met.
