Research On Pre-processing And Post-processing Of Plastic Injection Molding Simulation System

HSCAE is the newest generation numerical simulation commercial software for plastic injection molding, which is developed by HuaSu Software Research Center of HUST. It is designed and developed by modern software engineering method. It supports both surface model and three-dimensional model, and has friendly user interface. This paper focuses on the research of the system structure, pro-processing, post-processing of HSCAE.This paper deeply discusses the structure design of HSCAE, including logic flow analysis, topic identifying and modularization. Plastic injection molding simulation process can be divided into pro-processing, numerical simulation and post-processing. It includes such topics as: pro-processing, numerical simulation, expert system, data management and post-processing. It is composed of fast filling simulation, detail filling simulation, packing simulation, cooling simulation, stress analysis and warpage analysis modules.Graphic operation platform is an important component of HSCAE in post-processing. This paper presents the analysis and design of graphic operation platform in details, including the all-around design of this platform, innovative implement of graphic render, transformation in graphic operation and design of user interface.The runner system design has been a feature of HSCAE since version 5.5. This paper provides a new runner system design method base on runner center lines, which includes up-to-date runner system, such as hot runner system, valve gate. It also introduces how to exchange data with CAD system through IGES files.Grouped by the display mode, this paper dividually discusses the color-map graph, various curve graph, warpage result display. Based on above research, integrates mold movement and injection machine movement in injection, the author has developed virtual injection molding system. This paper also brings out a new design method of molding movement simulation, plastic injection machine movement simulation based on skeleton animation. Based on the analysis and research above, the author has accomplished most jobs of pre-processing and post-processing in HSCAE and has developed HSCAE system in cooperation with colleagues. As the gradual application of this system, the pre-processing and post-processing module researched in this article is proved performing well on the integrality of function, friendly on user interface.
