摘　　要：为了提高出风口的制造质量,从保证运动件的结构精度要求出发,在Moldflow模流分析及模具设计方面对出风口进行了详细的研究。详述了在模具制造前期如何利用Moldflow优化浇口设计,控制零件变形。为了提高出风口精度,采用可随时研配的单镶块设计。针对出风口模具常用的油缸滑块提出了一种全新的油缸设计选择方式,提出了一种特殊的、应用在出风口叶片模具中的定模斜顶结构,从而有效地保证了出风口的零件运动精度。In order to improve the manufacture quality of vehicle outlet and meet the dimen- sion requirement of moving parts, Moldflow analysis and mould design of the outlet have been implemented. The method to use Moldflow to choosc the gate location, gate size for optimizing the wrap and deflection before mould manufacturing were introduced. The insert block was adopted to improve the assembly precision, the hydro-cylinder of slide was chosen using stress formula. A special structure of cavity lifter for outlet blade mould was pro- posed. With these measures, the precision of outlet can effectively be controlled.
