摘　　要：对具有狭小凹槽结构的精铸小件,组树凹槽需朝向外侧,避免制壳涂料、撒砂堆积使凹槽处局部型壳过厚影响铸件凝固散热;同时设计浇注系统时需要考虑在热节部位设置内浇口保障补缩通道畅通,试制验证后确定合理铸造工艺方案。For small parts with narrow groove structure,the groove should be oriented outwards to avoid the accumulation of shell coating and sand powder,which may cause the local shell thickness at the groove to affect the solidification and heat dissipation of the casting.At the same time,when designing the pouring system,it is necessary to consider setting the inner gate at the hot section to ensure the smooth feeding channel,and determine a reasonable casting process plan after trial production verification.
