g forward to these design features in every mobile phone to achieve harmony and unity. Mobile Industrial designers have the responsibility and the ability to give consumers more to e. 2. The main content of the research Content: Nokia 2700 shell design and plastic injection molding Programme: 1. Design and draw and cavity injection mold assembly, core parts diagram, in line with plastic parts production requirements。 2. Using threedimensional CAD / CAM software for mold surface for CAD modeling。 3. Requirements of design drawings in line drawings。 4. Requires coherent thesis statement, design calculation is correct, the paper format specification. 3. Research and the development trend of domestic and foreign The development of mold Mold is an important industrial production technology and equipment, mold industry is the development of national economy, an important basis for the various departments, one after accession to the WTO, the economic exchanges are frequent, rapid economic development in countries around the world, China has gradually transformed into the world39。 s manufacturing center. At present, China has made significant development die, but pared with the advanced countries there are still large gaps. Such as: low precisionmade die, life is short, the manufacturing cycle length, forming equipment, the older, less brand specifications。 the use of new materials research and development efforts do not die, CAD / CAM. / CAE application level is still far behind the industrialized countries . Die CAD / CAM technology trends 21 basic features of the mold manufacturing industry is highly integrated, intelligent, flexible and work, and the goal is to improve product quality and production efficiency, shorten the design cycle and manufacturing cycle is short, lower production costs and maximize die the resilience of the manufacturing industry to meet customer needs. Concrete manifestation of the following: 1) standardized CAD / CAM systems can create standard parts database, a database of nonstandard parts and mold parameters database. Standard library in the CAD design of the parts can be called at any time, using GT (group technology) production. Stored in nonstandard parts library, although the structure and design of different needs, but the use of modeling system itself can easily be modified to speed up the design process, the typical mold structure library is based on the design parameters to achieve, according to user requirements to revise the structure of similar mold, can produce the required structure. 2) The integrated technology of modern mold design system should not only emphasize the integration of information, but should be emphasized that technology, and management integration. In the development of mold manufacturing system is stressed that more integrated concept, that is, information integration, intelligent integration, serial and parallel working mechanism of integration and to integrate it more suitable for future manufacturing systems. 3) The application of artificial intelligence technology to achieve intelligent technology product life cycle (including product design, manufacture, use) of all aspects of intelligence, to achieve the production process (including organization, management, planning, scheduling, control, etc.) all aspects of intelligence, and mold equipment, intelligent, but also between man and system integration and intelligence in which the full play. 4) The application of work technology, work technology, hardware and software integration, including implementation of various munication protocols and manufacturing automation protocol, the information munication interface, system operation control strategy is to achieve the basis for a variety of automated manufacturing systems. 5) MultiScience multifunctional integrated product design and technology used in future product development is not only a scientific theory and knowledge of machinery, but also use electromagism, optics, control theory and science and other knowledge. Product development to fullperformance multiobjective optimization design, a pursuit of static and dynamic characteristics of the mold product, efficiency, precision, service life, reliability, manufacturing costs and manufacturing cycle, the best bination. 6) The application of reverse engineering technology in many case。
