摘　　要：大型注塑产品往往拥有大量深而薄结构的加强筋,这极大影响模具的脱模结构设计。通过建立脱模力测量平台,采用PP材料进行实验,以研究注塑工艺参数与加强筋脱模力的关系。实验表明:不同的注塑工艺参数对加强筋脱模力影响程度不同,其中脱模温度对加强筋脱模力影响程度较大。并且根据实验结果,对脱模力理论公式进行修正。Large injection molding products often had a number of deeper and thinner strengthening rib, which greatly influenced demoulding structural design. Through established a platform to measure injection force, experienced with PP in order to study the relationship between injection parameters and ejection force of strengthening rib. Experiments showed that the effects of different injection parameters on the ejection force of strengthening rib were different. The demolding temperature had a greater influence on the ejection force of strengthening rib. And according to the experimental results, the demoulding force theory formula was amended.
