Abstract

A problem of modeling plastic injection forming (molding) is presented, including both the plasticizing system of the injection-forming machine and the mold. When modeling the plastic flow in the mold, the input quantities are essentially unknown, e.g., the plastic melt temperature. Thus, a comprehensive (global) model of the injection-forming process is needed for the flow in the plasticizing system and in the mold. The process output quantities from the plasticizing system will be the input quantities for the mold. When modeling the plastic flow in the injection-forming machine, a comprehensive approach should be applied to consider the solid material conveying, material plasticizing, and the material melt flow. The model of material plasticizing is a basis for building such global models. In this research, the effect of the flow (including plasticizing) in the injection-forming machine on the flow in the mold is studied by simulation (using Moldex3D 2023R3OR 64-bit software) and experimentation. These studies are carried out for the injection forming of selected material using a specialized spiral mold. Simulations performed with the use of Moldex3D software for the plasticizing system significantly improved the accuracy of the simulation of the flow in the mold. However, the best results were obtained using experimental data (plastic melt temperature) as input quantities for mold filling simulations. The novel concepts of injection-forming process modeling based on our previous experimentations are also discussed.

摘要

提出了一个塑料注射成型（模塑）的建模问题，包括注塑机的塑化系统和模具。在对模具中的塑料流动进行建模时，输入量基本上是未知的，例如塑料熔体温度。因此，需要一个注塑成型过程的综合（全局）模型来描述塑化系统和模具中的流动。塑化系统的过程输出量将作为模具的输入量。在对注塑机中的塑料流动进行建模时，应采用综合方法来考虑固体物料输送、物料塑化和物料熔体流动。物料塑化模型是建立此类全局模型的基础。在本研究中，通过模拟（使用Moldex3D 2023R3 OR 64位软件）和实验研究了注塑机中的流动（包括塑化）对模具中流动的影响。这些研究是针对使用专门的螺旋模具对选定材料进行注射成型进行的。使用Moldex3D软件对塑化系统进行的模拟显著提高了模具中流动模拟的准确性。然而，使用实验数据（塑料熔体温度）作为模具填充模拟的输入量时获得了最佳结果。还讨论了基于我们以前实验的注塑成型过程建模的新概念。
