Key words :Quick mold-making technology ;Rapid prototyping manufacture ;High speed manufacture.
The common saying say:" have no rules not to become the square circle", this" rules" is the molding tool in plastics process. In modern industry produce,60% industry product with 90% ～ needs to use the molding tool to process, the molding tool industry has already become a foundation industry within manufacturing industry, is the foundation of the technique result conversion, is the important realm of the high new technique industry again at the same time, the flourishing nation of industry of etc. is become in the Europe and America" the magnetic force industry" of" order the iron gold". Turn worse continuously along with the market globalization and competitions, the product renewal changes the speed of the generation to speed continuously, have another the small batch quantity of species and will become the important mode of production of the manufacturing industry, in this kind of case, manufacturing industry to product prototype of the fast manufacturing techenology of the fast manufacturing and molding tool put forward the strong request. Therefore, make the mold technique to present the animate development trend quickly. The conduct and actions makes the two greatest representatives of technical molds quickly: make the mold method( RT), the adoption high speed to slice to pare to process the inevitable meeting of molding tool( HSM) technically according to the fast prototype to get the faster development in very long period of time of future.
1 Fast prototype of molding tool manufacturing technique
1. 1 The fast prototype makes the technique to thought of put forward
The fast prototype manufacturing technique( the Rapid Prototyping Manufacture, RPM) expects to come from the United States after 80's in 20 centuries, is 20 a gravenesses of the manufacturing technique realm of the near in the last years worlds break, it is to accompany with the technical development of calculator technique, the laser technique and new materials but output, is a kind of all new manufacturing technique, the design that its ability will has already had several models of mathematics is quick, of oneself the thing changes in to have the certain structure and the prototype or the spare parts of the function. The technique of RPM acquires the path of the spare parts to differ from the traditional material to do away with or the material transform the method, but control in the calculator under according to long-lost pile up the principle, adopt the different method to pile up the material according to the spare parts CAD model most complete the spare parts to take shape eventually with the manufacturing technique, it has the height gentle and technical gather highly, design manufacturing the integral whole turn, fast, free shape manufacturing, characteristics of extensive of material, drive generally accepted is after technique of NC of a technique revolution.
1. 2 RPM general craft step
Because the technique of RPM can shorten the product development period clearly, the success rate of the exaltation product development, lower the development cost and invest the risk, so got the quick expansion application in the process of product develop, the technique of RPM got the further development. Since the 3 DSYSTEM company of the United States release the first Taiwanese business people the article SLA took shape the machine quickly, there has been more than ten different take shape the system quickly. Among them more mature have the methods, such as SGC, LOM, SLS , 3 Ds- P printings, FDM and IJ- Petc., some experts think that the ink-jet technique is a future
The trend of the development. Although exist the fast prototype technique of various each kind, its basic thoughts all make use of the calculator to order complicated 3D object conversions are 2D Layer, then from/ the line constitutes to face( layer), pursue the layer takes shape to get end of 3D spare parts models .Its craft step is:
