摘要
球墨铸铁玻璃瓶成型模具在使用过程中产生变形,导致所生产的瓶子合缝处产生错位而报废。通过对模具化学成分、硬度试验、金相组织进行分析,发现模具产生变形为材料方面的原因,使模具内部有大量疏松,合缝线处存在补焊等不利因素。
The glass bottle forming mold produced by a mold manufacturer has dislocation in the process of use,and one of them is sent for inspection to analyze the reason. Through the chemical composition analysis、hardness test and microstructure microscopic test of the die,it is found that the cause of the mold dislocation is caused by a lot of loose material and different repair welding process.
