With the continuous development of market economy, industrial products are developing in the direction of multi variety, small batch, high quality and low cost. Therefore, the requirements of mold, the key process equipment for forming various products, are higher. On the one hand, in order to pursue the scale benefit, the enterprise makes the mold develop towards the direction of high speed, precision and long life; on the other hand, in order to meet the needs of multi variety, small batch, fast product renewal and rapid market winning, the enterprise requires the mold processing to develop towards the rapid economic direction of short manufacturing cycle and low cost. The emergence of advanced computer technology in industrial production makes the rapid and economic mold making of plastic mold more powerful, the application scope is constantly broadened, the types are constantly increasing, and the economic benefits created are more and more significant.
In recent years, the mold CAD software is represented by mold wizard and Pro / E, which are developed by UGS company in USA. The injection mold design wizard provides users with injection mold design environment, tools and related knowledge, as well as rich standardized mold base library, parts library and insert library. Users can choose the standard mold base provided by the software or flexibly and conveniently establish their own standard mold base library. In various forms of dynamic and fixed mold structures, the parametric design of gate sleeve, draw bar and inclined bar is adopted Then, the demoulding mechanism and cooling system are designed to complete the final assembly of the mold, and realize the transformation from plastic parts to plastic parts
The rapid design process of mould. Users can use UG software to realize the whole process of plastic injection mold from design to numerical control processing and molding, practice the 3D mold design, reduce the mold design and manufacturing cycle time, and greatly improve the efficiency.
In the plastic mold industry, the CAE software is represented by Moldflow software. Its injection molding simulation analysis module (MPI) simulates and analyzes the whole injection molding process on the computer, including filling, packing, cooling, warping, fiber orientation, structural stress and shrinkage, and gas assisted molding analysis, so that designers can find out the possible defects of future products in the design stage In order to improve the success rate of one trial. After designing the product, the designer can get the optimized product design scheme and confirm the surface quality of the product in a very short time by using the product optimization consultant module (MPA) simulation analysis. his
Injection molding process control expert module (MPX for short) is an injection molding quality control expert integrating software and hardware. It can be directly connected with the injection molding machine controller to optimize the process and monitor the quality, automatically optimize the injection molding cycle, reduce the scrap rate and monitor the whole production process.
The interactive use of CAD and CAE Technology in injection molding can reduce the designer's dependence on experience, improve the success rate of one-time mold test, greatly shorten the mold processing design time, simplify the manufacturing and cutting process, optimize and control the injection process of injection molding machine, reduce the cost and improve the efficiency.
