摘　　要：提出在设计阶段对几何形状较复杂的注塑件产品进行并行成本估算的方法,引入特征概念,分析了注塑件产品的几何特征和设计特点,以及在设计阶段的成本估算策略;建立了以特征为基本处理单元的并行成本估算模型,研究了产品设计过程中特征变化对产品成本的影响。以一法兰盘注塑件为例进行了并行成本估算。A method of the concurrent cost evaluation at design stage for injection molding product with a complex geometry is presented. The concept of feature is introduced. The geometry features and the design characteristics are analyzed, and the strategy of the cost evaluation of injection molding product at design stage is presented. The concurrent cost evaluation model based on feature is built. The influence of the feature change at design stage on the product cost is studied. A simple example of flange injection molding product is applied to show the process of concurrent cost evaluation.
