[Abstract]:With the rapid development of plastic industry, plastic products have been widely used in the fields of automobile, household appliances, logistics, medical equipment, aerospace and so on. "plastic instead of wood" trend. Plastic products from its structure design to product molding is a complex process of design, manufacturing, process debugging and so on. Any link will have a great impact on the quality of the product. With the continuous development of plastic mould CAD / CAE technology, the traditional mold design and manufacture method is overturned. The rational use of CAD / CAE technology can find the problem and solve the problem in the product and mold structure design stage as soon as possible. Effectively shorten the product design cycle, reduce the cost of enterprises. In this paper, based on UG and Moldflow, the application of CAD / CAE technology in plastic product structure design, mold structure design and injection molding process optimization is studied based on UG and Moldflow. The three processes of process debugging can effectively link up, improve the efficiency of product development, and shorten the production cycle of plastic products as much as possible. The main contents of this paper are as follows: (1) with UG8.0 as the design platform, Workbench 14.5 as the analysis tool, combined with the general criteria of plastic product structure design, the structure of cup frame series products is designed and its three-dimensional model is established. Finally, Moldflow is used to evaluate the filling quality of its products.) first, Moldflow is used to analyze and optimize the optimum gate position and the optimal cooling circuit layout, then the UG8.0 / Mold Wizard module is combined with HBSMOULD, and according to the basic principle of mould design, Die structure design of cup frame series products includes mould frame system selection, dynamic mode design and slide block design, hot runner system, cooling system, exhaust system, ejection system and its auxiliary parts design. Finally, the overall assembly drawing of the cup frame is obtained. (3) the injection molding process simulation based on Moldflow software, including the simulation analysis of filling, cooling, keeping pressure, warping and so on, and the optimization of injection molding process are obtained, and the best molding process parameters are obtained. The process parameters are transformed into actual injection conditions, which provides scientific basis for mould testing. Through the research of this subject, it shows that the rational use of CAD / CAE technology can greatly improve the efficiency of collaborative work in three departments: product structure, mold design and injection molding process debugging. It provides an efficient method for enterprises and promotes the development of CAD / CAE technology.
