【正文】 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 cases, some products are not from the design concept, but the origin and some other products or in kind, to or in kind, only the prototype model, but not under the conditions of product design mold design and manufacturing in order to produce a finished product. At this point needs to physical measurement, physical measurement data and then use the CAD geometry model to restructure, this process is the reverse engineering. Reverse engineering to shorten the cycle from design to manufacturing is to help designers achieve concurrent engineering and other modern design concept is a powerful tool, on being present in the more widely used. 7) rapid prototyping rapid prototyping manufacturing technology is based on layer manufacturing principle, to create a prototype quickly, and with the geometric plexity of nothing to do, especially with plex surface shape in the manufacture of products can show their superiority. It not only can quickly create prototypes for design review, assembly verification, but also can copy the shape of the mold and quickly create a product, thus avoiding the cost of the traditional mold manufacturing, the high cost of NC machining, which in mold manufacturing RPM play an increasingly important role. 4. Pilot program 1. Analysis of mobile phone parts and plastic parts plastic molding technology and processes. 2. Design mobile phone plastic parts diagram. 3. Using the principle of injection molding for molding plastic parts of mobile phones. 4. And injection mold design and drawing and assembly drawing die cavity, core and some other parts diagram. 5. Using Mastercam software to the mold cavity, core threedimensional surface modeling and NC machining simulation, and production CNC machining process. 6. The design process can be processed using puter simulation test. MasterCAM is today widely used CAD / CAM software. Rational use of CAD / CAM software can significantly improve the mechanical design and processing quality and efficiency. This mobile phone model and shell mold process, for example, flexible use of MasterCAM on how to carry out mechanical design and process were discussed. 5. Tooling design parts Rectangle using the Rectangle mand MasterCAM, Arc mand draws Top surface contour, and to do with the Fillet mand to fillet processing, drawing out the Top side. Through entity Solids / Extrude mand to get physical contours of tensile 12mm. In the Front view, use Spline Curves, Arc mand draws the arc curve surface of the phone curves. Similarly, the use of physical tension Extrude mand, select the Extrude Chain Cut Body Options window to make it to the front surface of the Top physical entities drawn shear, that is, the Boolean operation squeezed entities, resulting in cell phone curved surface. Select Solids → Fillet fillet on the entity made to plete the design of the mold parts. In the drawing process, the application layer functionality Level design is very helpful. The curve can be different, separate entities, each of the layers in place, and its name be distinguished. Nothing needed shielding layer, so that simplified view, clear, easy to modify, reduce operational errors. 6. Tooling design entity 1. Airframe design Set the position plane, the view plane are the Top plane, the (0,0) the lower left corner point positioning in the mobile phone, according to The prototype design is pleted parts. Mobile phone keypad and the body is not the same as a whole, in body manufacturing, should be key part of the hole, so the per
