Treating and the modern mould make high speed    One, summarizes    1 the present situation that the mould makes at present and trend8844
    The mould is important handicraft equipment, occupies decisive position in industrid departments such as consumer goods , electrical equipment electron , automobile , aircraft fabrication. The mould is important handicraft equipment, occupies decisive position in industrid departments such as consumer goods, electrical equipment electron, automobile, aircraft fabrication. Industrial product part rough process 75%, the finish machining 50% and plastic part 90% will be completed from the mould. The Chinese mould market demand already reaches scale of 500 hundred million yuan at present. The automobile mould , the annual growth rate covering piece of mould especially will exceed 20 %; Also prompt building material mould development , various heterotype material the mould , wall surface and floor mould become new mould growth point , plastic doors and windows and plastic drain-pipe increase to exceeding 30 by in the upcoming several years %; The home appliance mould annual growth rate will exceed 10 %; The IT industry year increases % speed equally exceeding 20 , the need to the mould accounts for 20 of mould marketplace %.2004 annual Chinese machine tools implements industry output value will continue to increase. Our country mould fabrication market potential is enormous. The basis data counts, in recent years, our country mould year gross output value reaches 3 billion U. S. dollar, entrance exceeds 1 billion U. S. dollar, exceed 100 million U. S. dollar outlet. Increase by from 25% to increase to 2005 50% of 1995. The expert foretells that abroad: Asia portion being occupied by in mould fabrication in the whole world, will from 25% to increase to 2005 50% of 1995.
    Chinese mould industry has been expanding by leaps and bounds , has formed east China and two big South China bases, and has expanded gradually arriving at other province. In 2002 (Shandong, Anhui, Sichuan) in 1996 ~, mould manufacturing industry output value annual average growth 14%, grows by 25% in 2003. In 2003 our country mould output value is 45 billion RMB. The gross product place occupies the world the 3rd, exports a mould increases33.5% compared to last year 336,800,000 U. S. dollar. But, contents low our country technology moulds already pile up in excess of requirement, very most support of accurate, complicated top grade mould imports. Every year the entrance mould exceeds 1 billion U. S. dollar. Exceed 100 million U. S. dollar outlet.
    Precise mould accuracy requires that 3 mu ms , large-scale moulds require that 8000 satisfied kN agree well with model force injection machine request in 2 ~; The minitype mould needs the request satisfying the diameter 1 mm silent stock tube. At present, adopt quick-cutting to produce a mould already becoming the general trend that the mould makes, a few moulds have produced a manufacturer in abroad , high-speed machine tool large area has substituted the electric spark machine tool , quick-cutting has improved the mould efficacy greatly. Machine tool enterprise aims at mould manufacturing enterprises, some treating centres60% all above of the machine tool producing a factory sells treating enterprise to a mould. The mould fabrication enterprise substituting the electric spark finish machining mould gradually in abroad has adopt quick-cutting already commonly , quick-cutting has produced a mould already becoming the general trend that the mould makes gradually , has improved the mould efficacy and mass greatly. Adopt quick-cutting to replace electric spark producing a mould, can get on the stick obviously , improves mould accuracy , life time growing.
    2 high speed processes application in making in the mould
    2.1 quick-cutting merit:
    1) cutter high rotation rate and the machine tool height enter be given to and high acceleration , improve metal excision rate greatly; 模具制造加工英文文献和中文翻译:http://www.youerw.com/fanyi/lunwen_7334.html
