摘要
铸铁件变形问题是负压消失模铸造技术生产过程中的一种典型缺陷。消失模铸造的变形问题存在于生产全流程过程中,例如白模制作、施涂、烘干、放模、三维振实及浇注过程。本文通过研究各个工序变形产生的原因,并制定改进和控制措施,达到控制变形问题,最终形成一套负压消失模铸造过程尺寸控制的流程与措施。
Casting deformation is one typical defect of the vacuum lost foam casting during production.The deformation exists in the whole process such as lost foam pattern making,coating,drying,assembly,three-dimensional vibration compaction and pouring process.This subject researched and analyzed the cause in each process and made corrective action to control the deformation during production,and formed a lost foam casting dimension control methods from whole foundry practice process.
