通过对比不同的冒口处理方法对铸件补缩、生产过程的影响及对模具的要求,提出了一种新的冒口涂层复合处理方法,并分析了涂层结构,描述了涂层处理方法及施工工艺。通过在实际生产中应用,对冒口涂层复合处理方法进行了验证。结果表明,通过涂层复合处理后的冒口,使用寿命长、补缩效果良好、冒口体积小,是一种经济实用的工艺方法。 By comparing different riser processing methods on casting shrinkage, the impact of the production process and the requirements of the mold, a new riser coating composite treatment method, and analysis of the coating structure, describes the coating treatment method And construction technology. Through the application in the actual production, the riser coating composite treatment method was verified. The results show that the riser after coating composite treatment has long service life, good feeding effect and small riser volume, which is an economical and practical process.
