【正文】 ore powerful, the application 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 fast economical pattern making technology and the traditional machinefinishing pares, 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. fast prototypes manufactures technology The fast prototype manufacture technology is called RPM, is one kind of new manufacture technology which the 8039。s characteristics is to make the mold cost low, the period is short, being applicable to create the lamella large pull to stretch the mold and hurtle to cut the mold and plastics molds. resin pounds model the molding tool technique This is a kind of to take the kind mold( or the craft model) as the basis, taking resin or its pound materials as the fluid material, sprinkling the convex( cave) mold of outpouring first, again the convex( cave) mold of basis sticks up the wax slice( the cleft layer), sprinkling to note the convex( cave) surface that that technique model does not need the machine to that technique and CAD/ CAMs bine together, the characteristics is the molding tool size accuracy high, the manufacturing period is short, the cost is low, is the new product manufacture on a trial basis, the small batch quantity produces the craft material of new applicable to the creation large overlay the piece to pull to stretch the mold( also can the part inset the steel), vacuum to absorb the and gather the ammonia ester hair bubble to model the mold, porcelain and ceramics mold and imitate the type to depend the mold and cast mold etc.. rubbers of system mold technique That technique take making a prototype or models as the basis, making into soft rubber of system piece, then depend the high pressure dint and models to fit together pletely. extrusions takes shape the technology cold extrusions takes shape Using the berylliuim copper alloy good thermal conductivity and the stability, after 5 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. ultra models takes shape the pattern making technology 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. 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 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。s attention. At present developed industrial nation some big panies traded the mold speed to achieve astonishing degree, whether had fast trades the mold technology to bee for an enterprise technology advancement sign. The always tendency is reduces 7 the mold to install on the equipment, to be fixed, the adjustment time, this both must give in the equipment structural design to consider, and must in the mold structural design, the standardized aspect consider, machine on work as far as possible placing machine under will do. ramming units bination technology The ramming unit bination technology is dies a resolve into each one simple unit the convention to die, according to the working procedure request, the arrangement bination, pletes the many kinds of ramming working procedure when the identical inferior stroke the new craft equipment, the work the ramming unit not with the punch press slide joint, only needs the slide attack then to plete the ramming work. When independent employment it is 1 plete mold. It may use for to process the sheet or the molding punch holes, falls the material, cuts the angle, the grooving, shuts off and the shallow stretch and so on. Has the assembly strongly, the easy to operate, the versatility, the efficiency is quickly good and so on the characteristic, suits the multi varieties specially, center the production. cutting edges builtup weldings technology In dies in the manufacture, take the ordinary gray iron as the substrate, in t
