摘　　要：通过运用TRIZ创新理论中的因果链分析法,对长杆类铸件存在的质量问题进行了可能的原因分析;根据分析出的可能性原因,利用TRIZ理论中的预先作用法原理、中介物原理等逐一采取了相应的工艺措施。经过生产验证,长、短支撑杆尺寸及内部质量均能满足标准要求。在长支撑杆和短支撑杆的工艺设计中,运用不同浇注重量进行内浇口截面按比例设计,实现了两种不同类铸件在同一浇注系统下浇注生产。Analyzed the possible causes of the existing quality problems in long rod castings through Cause-Effect Chain Analysis method in TRIZ innovation theory.According to the analyzed possible reasons,take technological measures based on the principle of pre-action and intermediary principle in the TRIZ theory.After production verifcation,the size and internal quality of long and short support rods can meet the standard requirements.In the process design of long and short support rod,different casting weights were used to design the inner gate section according to the proportion,which realized the casting production of two diferent types of castings under the same pouring system.
