1、 1 Modern fast economy manufacture mold technology Along with the global economy development, the new technological revolution made the new progress and the breakthrough unceasingly, the technical leap development already becomes the important attribute which the impetus world economics grew. The ma

2、rket economy unceasing development, urges the industry product more and more to the multi- 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, thereupo

3、n to makes 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 long life direction develops； On the other hand enterprise in order to satisf

4、y the multi- varieties, the product renewal quickly, wins the market the need, requests the mold to turn towards the manufacture cycle to be short, the cost low fast economy direction develops. The computer, the laser, electronic, the new material, the new technical development, causes the fast econ

5、omical pattern making technology even more powerful, the application scope expands unceasingly, the type increases unceasingly, the creation economic efficiency and the social efficiency are more and more remarkable. The fast economical pattern making technology and the traditional machine-finishing

6、 compares, has the pattern making cycle short, the cost is low, the precision and the life can satisfy in the production the operation requirements, is synthesizes an economic efficiency quite remarkable kind to make the mold the technology, summarizes below, has several types to leave. 1 fast proto

7、types manufactures technology The fast prototype manufacture technology is called RPM, is one kind of new manufacture technology which the 80s later period develops. US, Japan, England, Israel, Germany, China have all promoted own commercialization product, and has formed the new industry gradually.

8、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 (CNC) synthesizes the application the high technology and new technology. In takes shape in the concept take the plane sep

9、arate, piles up as the instruction, in the control take the computer and the numerical control as 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

10、 RPM technology to be 2 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. 2 surfaces take shape the pattern making technology The surface takes sha

11、pe the pattern making technology, mainly is the use spurts 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 kind of types. electric a

12、rcs 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 circular telegrams tinsel to melt the tinsel, depends upon the compressed gas its full atomization, and gives the ce

13、rtain kinetic energy, high speed sprays in the type mold surface, layer upon layer mounts, forms a metal 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 in

14、tensity and the rigidity, 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 hours, saves the energy and the metal material, general cavity su

15、rface 2-3mm is only thick, simulation greatly strengthened, the pattern precision may achieve 0.5 mu m. At present this technology widely uses in superficial shape and so on airplane, automobile mold, electrical appliances, furniture, shoemaking, fine arts handicraft is complex and the pattern fine

16、each kind of polyurethane product blow molding, attracts models, the PVC injection, PU becomes spongy and each kind of injection takes shape in the mold. electrolytic castings take shape the technology The electrolytic casting takes shape the technical principle to be same with the galvanization, is

17、 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 in the electrolytic casting fluid the metallic ion to return to original state a latter place deposition

18、on the type mold, forms the metal shell, after strips it, contacts the surface with the type mold namely for the 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, en

19、hanced the resistance to wear 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 3 electric spark and so on bakelite mold, glass mold, compression casting mol

20、d takes shape the electrode manufacture. cavities surfaces fine pattern takes shape etching technology The etching technology is optics, chemistry, the machining synthesis application one kind of technology, its basic principle is makes first the pattern design the film, then in has spread the film

21、on pattern design duplication the photosensitive material on the mold cavity surface, process chemistry processing, the mold cavity surface does not form by the etching partial protectors, then acts according to the mold material quality, the choice corresponding etching craft, pattern design etchin

22、g in mold internal surface.This technical main characteristic is the time short, the expense is low, patching damages the pattern design to be possible to achieve flawlessly. 3 sprinkle to cast into the type system mold technique Sprinkling to cast into technical and common characteristics of the ty

23、pe system mold is according to the kind piece for basis, sprinkle a convex and cave mold, a surface do not need the machine to process.Make physically to mainly have following several categories type in the mold. 4 extrusions takes shape the technology Using the berylliuim copper alloy good thermal

24、conductivity and the stability, after the solid melt aging treatment of metal, use the swaging pressure to make the mold concave model cavity. Its characteristic is makes the cycle short, the cavity precision is high (the IT7 level), surface roughness Ra=0.025 mu m, The intensity is high, the life m

25、ay reach 500,000 times, does not have the environmental pollution. This technology is using the metal material in the thin crystal grain, certainly takes shape the temperature, under the low distortion speed condition, when the material has the best superplasticity, toes attend to carry out raised m

26、old which the initiative finishes, then may extrude the concave mold with the small strength one kind of fast economical pattern making technology. Ultra models takes shape material typical representative is Zn-22%AL. 5 does not have the mold multi- spots forming technology Does not have the mold mu

27、lti- spots fast forming technology is by CAD/CAM/CAT The technology is the main method about, may adjust the base main body group highly using the computer control to form forms the surface, replaces the traditional mold to carry on the three dimensional curved surface forming to the sheet an modern advanced manufacture technology. This technology may change the distortion way and the stressful condition at will, enhances the material the formed limit, may form repeatedly, by this elimination material interior remaining stress, the realization does not have
