浅谈铸件外观质量的提升

Simple Introduction about Outer Quality Improvement of Castings

介绍了铸件外观质量的具体体现,归纳了模具、砂型、砂芯和后序清理等工序的关键控制要素,重点指出:(1)铸模、芯盒起模斜度要合理,确保良好的起模性;(2)要重视模具、芯盒的日常维护保养和修理;(3)起模后的砂型、砂芯应该进行很好地保护,防止磕碰伤;(4)开箱清理工序要注意保护铸件,避免不当修磨和过度修磨损伤铸件,制定合理的铸件清理运行方案,减少铸件吊运次数,合理的工序检测,避免磕碰、损害铸件外观,提升工作效率。

The concrete embodiment of the casting outer quality was introduced,the control essential factors of the procedures including pattern tools,sand mold,sand core and subsequent cleaning were summed up. The followings were highlighted:(1)The pattern draft and core box draft must be reasonable to guarantee good liftability.(2)Attention should be paid to the routine maintenance and repair of the pattern and core box.(3)The sand molds and cores drafted out from the pattern and box should be safeguarded to avoided bump injury.(4)Attention should paid to protecting castings in the knock-out and cleaning procedures to avoid casting damage due to inappropriate and excessive grinding. A reasonable operation plan should be drawn for casting cleaning to reduce hoisting times,procedure inspection should be reasonable,collide damage of casting outer quality should be avoided to improve work efficiency.
