Research On Large Injection Mold Design Knowledge Management System

The die & mould industry developed very rapidly during the "Ten Five" in our country. The output of mold production and the volume of demand are increasing under the drive of national economy development and the encouragement of national industry policy. But the laggard integrated level of whole mold industry was not radically changed, especially in the large precise complex injection mold production area, there is a largish disparity compared to the developed countries: the equipment backwards above 5 years;the management backwards above 8 years;the technology and the technologist backwards above 10 years. In other words, it has become a bottleneck on the future development of nation mould industry that the low capacity of large injection mold design and the out-of-date level of control. Whereas this present status in mould industry, lots of mould enterprises have been on to the importance of the explicit knowledge management with the development of information technology and the mould enterprise management consciousness enhancement. Many mould enterprises have used the computer to manage the product data and information. For example, the product data management (PDM) had used in many enterprises. But most of them have not take any measurement to manage the tacit knowledge like the designers' experience that is very importance to the technique innovation.The thesis is concerned mainly on the project of "The digitized manufacture of car's large precise complex injection mold", which is a key industries project of the Guangdong province. On the basis of studying about the design knowledge of the large injection mold like the fender-guard, we develop the design knowledge management system of large injection mold that is based on Borland Delphi 7.0 and MS SQL Server 2000. This paper mainly includes the following contents:1. By combining the research on the current knowledge management (KM) theories and the analysis of relationship and differences between knowledge management and information management with the analysis of design cycle and design knowledge architecture of large injection mold, the management model of large injection mold design knowledge was constructed.2. The knowledge management was brought into the field of large injection mold design knowledge management. On the point of knowledge management view, the large injection mold design knowledge was classed, and their management methods were researched. Finally, the large injection mold design knowledge management system was constructed.3. The whole design knowledge of large injection mold was divided into two parts: the explicit knowledge and the tacit knowledge. The method of coding management was used to manage the explicit knowledge, and the knowledge distribution map was used to manage the tacit knowledge.4. Adopting Borland Delphi 7.0 and MSSQL Server 2000, we developed the large injection mold design knowledge management system. This software primarily achieves the following functions such as: browse, search, share and communicate with each other and so on.According to the research, we achieved the management of large injection mold design knowledge primarily and developed the software. Users can search the knowledge rapidly, calculate conveniently, browse the knowledge distribution and through it to find the information of the expert through this management platform. Others, the system has the following features: simple interface, easy to use, favorable man-machine conversation, expandability, transplantation, and so on.
