目前,注塑模具数值模拟主要集中在产品的成型过程模拟,较少考虑模具在成型过程中的受力变形。研究注塑成型过程中模具变形对于减少模具重量、节约成本、提高产品性能具有重要意义。基于载荷映射的注塑模具结构分析方法,是将注塑成型数值模拟分析结果施加到模具型腔有限元模型表面作为力边界条件,从而能够更加真实的对注塑模具零件进行结构分析。其中,对于注塑模具的网格信息和模流结果信息的读取为首要关键步骤。本文就是在此基础上,提出了一种基于载荷映射的注塑模具信息的读取研究方法。
At present, the numerical simulation of injection mold mainly focuses on the simulation of the molding process of the product, and less considers the force deformation of the mold during the molding process. It is important to study mold deformation during injection molding to reduce the weight of mold, save cost and improve product performance. The structure analysis method of injection mold based on load mapping is to apply the result of numerical simulation of injection molding to the surface of the finite element model of the mold cavity as the force boundary condition so as to be able to carry out the structural analysis of the injection mold parts more truly. Among them, the injection mold for the grid information and the results of the flow of information to read as the most important key steps. Based on this, this paper presents a method for reading information of injection mold based on load mapping.
