【正文】 ral cavity surface 23mm is only thick, simulation greatly strengthened, the pattern precision may achieve 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 plex and the pattern fine each kind of polyurethane product blow molding, attracts models, the PVC injection, PU bees 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 according to model the mold (readymade 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 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, enhanced the resistance to wear and the life, roughness, the size precision is pletely 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 bakelite mold, glass mold, pression casting mold 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 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 etching in mold internal 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 mon characteristics of the type system mold is 12 according to the kind piece for basis, sprinkle a convex and cave mold, a surface do not need the machine to physically to mainly have following several categories type in the mold. 4 extrusions takes shape the technology Using the berylliuim copper alloy good thermal 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= mu m, The intensity is high, the life may 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 mold 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 Zn22%AL. 5 does not have the mold multi spots forming technology Does not have the mold multi 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 puter 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 the snapping back forming 6 triumphant Uygur bright steel belt blanking falls the material pattern making technology The new steel belt blanking falls the material pattern making technology is one kind is different with has raised, the concave mold structure steel belt mold generally, it is with specially makes the new fast economical pattern making technology by the single edge steel belt which the backing strip is posed. This kind of mold weight is light, only then 200kg, the processing precision for 177。 the majority enterprise still the tax burden is only overweight. The mold enterprise carries on the technological transformations introduction equipment to have to pay the considerable amount the tax money, affects the technology advancement, moreover privately operated enterprise loan extremely difficult. (2) Talented person serious insufficient, the scientific research development and the technical attack investment too urine mold profession is the technology, the fund, the work crowded industry, along with the time progress and the technical development, grasps the talented person which and skilled utilizes the new technology exceptionally short, the highquality mold fitter and the enterprise management talent extremely is also anxious. Because the mold enterprise benefit unsatisfactory and takes insufficiently the scientific research development and the technical attack, the scientific research unit and the universities, colleges and institutes eye stares at is creating ine, causes the mold profession invests too few 9 in the scientific research development and the technical attack aspect, causes the mold technological development ste
