2.8.4 cutting edges built-up weldings technology
In dies in the manufacture, take the ordinary gray iron as the substrate, in the cutting edge spot built-up welding high degree of hardness alloy steel, by replaces the molding tool steel to inlay the block, this technology becomes one of world advanced crafts. This is an item saves the manufacture man-hour, saves the expensive mold steel products, reduces the mold manufacture cycle the fast economical pattern making technology.
At present melts extremely the argon are welding technology application, enhanced the cutting edge built-up welding speed and the quality greatly. This technology various countries mold profession has widely used, has obtained the good economic efficiency.
2.8.5 solid casting die the cutting edge to inlay the block\\technology
This is one kind dies the cutting edge method with the solid casting technique manufacture, namely inlays the block with the alloy-steel castings to replace forges the alloy steel to inlay the block. At present because the casting craft and the heat treatment craft consummate and the enhancement unceasingly, the casting inlaid the block the intrinsic quality to have the guarantee, therefore its application scope was expanding unceasingly. This item by casts the new technical prominent characteristic which the generation hammers saves the precious mold steel products, simplifies the mold manufacture working procedure, because the processing remainder is small, has saved the massive machining man-hour, reduces the mold manufacture cycle, reduces the mold cost.
2.8.6 may process the plastic in mold manufacture application
May process the plastic to be common in the developed industrial nation application, specially in manufacturing industry and so on automobile, airplane, mainly replaces the lumber or the metal manufacture automobile body host model, the profile, examines has and the casting model and so on. May process the plastic the main characteristic is has both the lumber and the metal fine workability, the manufacture craft simple and direct(may use compression molding, pour, spells sticks, method well and so on sculpture), the size stability, does not distort, bears moistly, anti-corrosive, is easy to repair, the easy modification, the weight light, the manufacture cycle short, the cost to be low.
3 concluding remark
Fast economical pattern making technology type very many, its has the characteristic, the application scope are various, this article only can broadly make some simple introductions, each kind of technology still had many concrete technological processes, the craft parameter and it's the technical characteristic in the concrete application and the implementation process.
The mold is one of foundation industries, in the globalization market economy and under each kind of high technology and new technology swift and violent development situation, the fast economical mold has entrusted with the new mission and the brand-new connotation, the classification increases unceasingly, the fast economical pattern making material turns towards the multi-varieties seriation to make great strides forward, the craft has the new innovation and the breakthrough unceasingly, is published one after another with it supplementary equipment, the service domain in opens up unceasingly, the creation economic efficiency is more and more remarkable. Along with the commodity economy development, the intense market competition, the product renewal acceleration, is reducing the cycle to the fast economical pattern making technology, reduces the cost, will increase the precision and lengthens the life aspect the request to be able to be more and more high inevitably. Because it can cause the enterprise to win the market, creates the remarkabe economic efficiency, more and more receives entrepreneur’s favor and the concerned leader department’s enormous attention and the policy fund support. Each kind of fast economical pattern making technology also can consummate mature and the development unceasingly in the promoted application process, as a result of the high technology and new technology development, each kind of technical bonding with the seepage, for the adaption production in different demand, surely will be able to form some, the frugal energy, the frugal material fast pattern making technology new from now on.
