2、easingly, the technical leap development already becomes the important attribute which the impetus world economics grew. The market economy unceasing development, urges the industry product more and more to the multi-

3、 varieties, high grade, the low cost direction to develop, in order to maintain and strengthens the product in market competitive power, product development cycle, production cycle more and more short, thereupon to mak

4、es each kind of product the essential craft equipment mold request to be more and more harsh. On the one hand the enterprise for the pursue scale benefit, causes the mold to turn towards high speed, is precise, the l

5、ong life direction develops; On the other hand enterprise in order to satisfy the multi- varieties,, the product renewal quickly, wins the market the need, requests the mold to turn towards the manufacture cycle to be

6、short, the cost low fast economy direction develops. The computer, the laser, electronic, the new material, the new technical development, causes the fast economical pattern making technology even more powerful, the a

7、pplication scope expands unceasingly, the type increases unceasingly, the creation economic efficiency and the social efficiency are more and more remarkable. 2 fast economical pattern makings technologies type The

8、fast economical pattern making technology and the traditional machine-finishing compares, has the pattern making cycle short, the cost is low, the precision and the life can satisfy in the production the operation requ

9、irements, is synthesizes an economic efficiency quite remarkable kind to make the mold the technology, summarizes below, has several types to leave. 2.1 fast prototypes manufactures technology The fast prototype ma

10、nufacture technology is called RPM, is one kind of new manufacture technology which the 80's later period develops. US, Japan, England, Israel, Germany, China have all promoted own commercialization product, and ha

11、s formed the new industry gradually. RPM is the computer, the laser, the optical scanning, the advanced new material, the computer-aided design (CAD), the computer assistance processing (CAM), the numerical control

12、(CNC) synthesizes the application the high technology and new technology. In takes shape in the concept take the plane separate, piles up as the instruction, in the control take the computer and the numerical control a

13、s the foundation, take biggest flexibility as general goals. It has abandoned the traditional machine-finishing method, to the manufacturing industry transformation is a significant breakthrough, uses the RPM technolo

14、gy to be possible directly or indirectly the fast pattern making, this technology already by profession widespread application and so on automobile, aviation, electrical appliances, ships, medical service, mold. Under

15、summarized already commercialization continuously, the basis lamination software selectively deposits the liquid cementing material by the level on the powder level, finally piles up a three dimensional entity by the s

16、mooth printing two-dimensionalleve Justs like does not use the laser the fast pattern making technology. This technical main application takes shape in advance in the cermet compound materials porous ceramics on, its g

17、oal is produces the mold or ??? the manufacture directly by the CAD product model. 2.2 surfaces take shape the pattern making technology The surface takes shape the pattern making technology, mainly is the use spurts

18、 spreads, the electrolytic casting, chemistry corrosion and so on the new technique formation cavity surface and the fine pattern one kind of craft technology, in the practical application including following several

19、kind of types. 2.2.1 electric arcs spurt spread take shape the pattern making technology The electric arc spurts spreads takes shape the technical principle is: Has the electric arc quantity of heat using between 2

20、circular telegrams tinsel to melt the tinsel, depends upon the compressed gas its full atomization, and gives the certain kinetic energy, high speed sprays in the type mold surface, layer upon layer mounts, forms a met

21、al shell, namely the cavity internal surface, uses to fill the substrate material again (generally for metal silt and resin compound materials) performs to support the reinforcement, enhances its intensity and the rig

22、idity, combines the mold together with the metal pattern frame. This kind of pattern making technology craft simple, cost low, manufacture cycle extremely short, the cavity surface takes shape only needs for several ho

23、urs, saves the energy and the metal material, general cavity surface 2-3mm is only thick, simulation greatly strengthened, the pattern precision may achieve 0.5 mu m. At present this technology widely uses in superfi

24、cial shape and so on airplane, automobile mold, electrical appliances, furniture, shoemaking, fine arts handicraft is complex and the pattern fine each kind of polyurethane product blow molding, attracts models, the P

25、VC injection, PU becomes spongy and each kind of injection takes shape in the mold. 2.2.2 electrolytic castings take shape the technology The electrolytic casting takes shape the technical principle to be same with

26、 the galvanization, is according to model the mold (ready-made product or female mold which makes according to product blueprint) is the datum (negative pole), places in the electrolytic casting fluid (anode), causes

27、in the electrolytic casting fluid the metallic ion to return to original state a latter place deposition on the type mold, forms the metal shell, after strips it, contacts the surface with the type mold namely for the

28、mold the cavity internal surface. This technical main characteristic is saves material, the mold manufacture cycle short, electrolytic casting level degree of hardness may reach 40HRC, enhanced the resistance to wear

29、 and the life, roughness, the size precision is completely consistent with the type mold, is suitable for the injection, attracts models, the blow molding, keeps out models, mold cavity and the electric spark and so on

30、 bakelite mold, glass mold, compression casting mold takes shape the electrode manufacture. 2.2.3 cavities surfaces fine pattern takes shape etching technology The etching technology is optics, chemistry, the machin
