北美地区双腔节流阀体压铸不良品分析及对策

Die-casting Defects Analysis and Countermeasures of North America Double-cavity Throttle Body

介绍了北美地区双腔节流阀体的产品结构、模具结构以及压铸生产过程中出现的主要缺陷。运用压铸填充的P-Q^2关系对浇注系统设计进行了验证,利用模流分析软件对溢流排气系统进行了分析,并针对性地采取了措施,有效地降低了压铸件废品率。

The product structure,die-casting mold structure and main defects in the double cavity throttle valve body were analyzed.The design of the gating system was verified by using the P-Q^2 formula of die-casting system,and the overflow exhaust system was analyzed by using the mold flow analysis software.Some measures were taken to reduce effectively the reject rate of the product.
