1、The mold designing and manufacturingThe mold is the manufacturing industry important craft foundation, in our country, the mold manufacture belongs to the special purpose equipment manufacturing industry. China although very already starts to make the mold and the use mold, but long-term has not for
2、med the industry. Straight stabs 0 centuries 80s later periods, the Chinese mold industry only then drives into the development speedway. Recent years, not only the state-owned mold enterprise had the very big development, the three investments enterprise, the villages and towns (individual) the mol
3、d enterprises development also rapid quietly.Although the Chinese mold industrial development rapid, but compares with the demand, obviously falls short of demand, its main gap concentrates precisely to, large-scale, is complex, the long life mold domain. As a result of in aspect and so on mold prec
4、ision, life, manufacture cycle and productivity, China and the international average horizontal and the developed country still had a bigger disparity, therefore, needed massively to import the mold every year .The Chinese mold industry must continue to sharpen the productivity, from now on will hav
5、e emphatically to the profession internal structure adjustment and the state-of-art enhancement. The structure adjustment aspect, mainly is the enterprise structure to the specialized adjustment, the product structure to center the upscale mold development, to the import and export structure improve
6、ment, center the upscale automobile cover mold forming analysis and the structure improvement, the multi-purpose compound mold and the compound processing and the laser technology in the mold design manufacture application, the high-speed cutting, the super finishing and polished the technology, the
7、 information direction develops .The recent years, the mold profession structure adjustment and the organizational reform step enlarges, mainly displayed in, large-scale, precise, was complex, the long life, center the upscale mold and the mold standard letter development speed is higher than the co
8、mmon mold product; The plastic mold and the compression casting mold proportion increases; Specialized mold factory quantity and its productivity increase; The three investments and the private enterprise develops rapidly; The joint stock system transformation step speeds up and so on. Distributes f
9、rom the area looked, take Zhejiang Delta and Yangtze River delta as central southeast coastal area development quickly to mid-west area, south development quickly to north. At present develops quickest, the mold produces the most centralized province is Guangdong and Zhejiang, places such as Jiangsu
10、, Shanghai, Anhui and Shandong also has a bigger development in recent years.Although our country mold total quantity had at present achieved the suitable scale, the mold level also has the very big enhancement, after but design manufacture horizontal overall rise and fall industry developed country
11、 and so on Yu De, America, date, France, Italy many. The current existence question and the disparity mainly display in following several aspects:(1) The total quantity falls short of demand Domestic mold assembling one rate only, about 70%. Low-grade mold, center upscale mold assembling oneself rat
12、e only has 50% about.(2) the enterprise organizational structure, the product structure, the technical structure and the import and export structure does not gatherin our country mold production factory to be most is from the labor mold workshop which produces assembles oneself (branch factory), fro
13、m produces assembles oneself the proportion to reach as high as about 60%, but the overseas mold ultra 70% is the commodity mold. The specialized mold factory mostly is large and complete, small and entire organization form, but overseas mostly is small but, is specially small and fine. Domestic lar
14、ge-scale, precise, complex, the long life mold accounts for the total quantity proportion to be insufficient 30%, but overseas in 50% above 2004 years, ratio of the mold import and export is 3.7:1, the import and export balances the after net import volume to amount to 1.32 billion US dollars, is wo
15、rld mold net import quantity biggest country .(3) The mold product level greatly is lower than the international standardThe production cycle actually is higher than the international water broad product level low mainly to display in the mold precision, cavity aspect and so on surface roughness, li
16、fe and structure.(4) Develops the ability badly, economic efficiency unsatisfactory our country mold enterprise technical personnel proportion lowThe level is lower, also does not take the product development, and is frequent in the passive position in the market. Our country each mold staff average
17、 year creation output value approximately, ten thousand US dollars, overseas mold industry developed country mostly 15 to10, 000 US dollars, some reach as high as 25 to10, 000 US dollars, relative is our country quite part of molds enterprises also continues to use the workshop type management with
18、it, truly realizes the enterprise which the modernized enterprise manages few To create the above disparity the reason to be very many, the mold long-term has not obtained the value besides the history in as the product which should have, as well as the most state-owned enterprises mechanism cannot
19、adapt the market economy, but also has the following several reasons: .(1) Country to mold industry policy support dynamics also insufficientlyAlthough the country already was clear about has promulgated the mold profession industrial policy, but necessary policy few, carried out dynamics to be weak
20、. At present enjoyed the mold product increment duty enterprise nation 185; 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 techn
21、ology 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 p
22、rogress and the technical development, grasps the talented person which and skilled utilizes the new technology exceptionally short, the high-quality mold fitter and the enterprise management talent extremely is also anxious. Because the mold enterprise benefit unsatisfactory and takes insufficientl
23、y the scientific research development and the technical attack, the scientific research unit and the universities, colleges and institutes eye stares at is creating income, causes the mold profession invests too few in the scientific research development and the technical attack aspect, causes the m
24、old technological development step doe not to be big, progresses does not be quick.(3) The craft equipment level is low, also is not good, the using factor is low. Recent years ,our country engine bed profession progressed quickly, has been able to provide the quite complete precision work equipment
25、, but compared with the overseas equipment, still had a bigger disparity. Although the domestic many enterprises have introduced many overseas advanced equipment, but the overall equipment level low are very more than the overseas many enterprises. As a result of aspect the and so on system and fund
26、 reason, introduces the equipment not necessary, the equipment and the appendix not necessary phenomenon are extremely common, the equipment utilization rate low question cannot obtain the comparatively properly solution for a long time .(4) Specialization, standardization, commercialized degree low
27、, the cooperation ability Because receives large and complete small and entire the influence since long ago, mold specialization level low, the specialized labor division is not careful, the commercialized degree is low. At present domestic every year produces mold, commodity mold minister 40% about
28、, other for from produce uses for oneself. Between the molds enterprise cooperates impeded, completes the comparatively large-scale mold complete task with difficulty. Mold standardization level low, mold standard letter use cave rare is low also to the mold quality, the cost has a more tremendous i
29、nfluence, specially has very tremendous influence.(5) To the mold manufacture cycle) the mold material and the mold correlation technology fall The mold material performance, the quality and the variety question often can affect the mold quality, the life and the cost, the domestically produced mold
30、ing tool steel and overseas imports the steel products to compare has a bigger disparity. Plastic, plate, equipment energy balance, also direct influence mold level enhancement.At present, our country economy still was at the high speed development phase, on the international economical globalizatio
31、n development tendency is day by day obvious, this has provided the good condition and the opportunity for the our country mold industry high speed development. On the one hand, the domestic mold market will continue high speed to develop, on the other hand, the mold manufacture also gradually will
32、shift as well as the transnational group to our country carries on the mold purchase trend to our country extremely to be also obvious. Therefore, will take a broad view the future, international, the domestic mold market overall development tendency prospect will favor, estimated the Chinese mold w
33、ill obtain the high speed development under the good market environment, our country not only can become the mold great nation, moreover certainly gradually will make the powerful nation to the mold the ranks to make great strides forward. 15 period, the Chinese mold industry level not only has the
34、very big enhancement in the quantity and the archery target aspect, moreover the profession structure, the product level, the development innovation ability, enterprises system and the mechanism as well as the technology advancement aspect also can obtain a bigger development .The mold technology ha
35、s gathered the machinery, the electron, chemistry, optics, the material, the computer, the precise monitor and the information network and so on many disciplines, is a comprehensive nature multi-disciplinary systems engineering. The mold technology development tendency mainly is the mold product to
36、larger-scale, precise, more complex and a more economical direction develops, the mold product technical content unceasingly enhances, the mold manufacture cycle unceasingly reduces, the mold production faces the information, is not having the chart, is fine, the automated direction develops, the mo
37、ld enterprise to the technical integration, the equipment excellent, is producing approves the brand, the management information, the management internationalization direction develops. Mold profession in 十15 period needs to solve the key essential technology should be the mold information, the digi
38、tized technology and precise, ultra fine, high speed, the highly effective manufacture technology aspect breakthrough Along with the national economy total quantity and the industry product technology unceasing development, all the various trades and occupations to the mold demand quantity more and
39、more big, the specification more and more is also high.Although mold type many, but its development should be with emphasis both can meet the massive needs, and has the comparatively high-tech content, specially at present domestic still could not be self-sufficient, needs the massive imports the mo
40、ld and can represent the development direction large-scale, precise, is complex, the long life mold. Standard letter type, quantity, level and the production of the mold have significant influence to the entire mold profession development. Therefore, some important mold standard letters also must pr
41、ioritize, moreover its development speed should quickly to the mold development speed, like this be able unceasingly to raise our country mold standardization level, thus improves the mold quality, reduces the mold production cycle, reduces the cost. Because our country mold product holds the bigger
42、 price superiority in the international market, therefore regarding the exportation prospect good mold product also should take key develops. According to the above required quantity big, the technical content is high, represents the development direction, the export prospect good principle choice p
43、rioritize product, moreover chooses the product to have at present to have the certain technology base, belongs has the condition, has the product which the possibility develops .模具设计与制造 模具是制造业的重要工艺基础，在我国模具制造属于专用设备制造业。中国虽然很早就开始制造模具和使用模具，但长期未形成产业。直到20世纪80年代后期，中国模具工业才驶入发展的快车道。近年，不仅国有模具企业有了很大发展，三资企业、乡镇
44、（个体）模具企业的发展也相当迅速。 虽然中国模具工业发展迅速，但与需求相比，显然供不应求，其主要缺口集中于精密、大型、复杂、长寿命模具领域。由于在模具精度、寿命、制造周期及生产能力等方面，中国与国际平均水平和发达国家仍有较大差距，因此，每年需要大量进口模具。 中国模具产业除了要继续提高生产能力，今后更要着重于行业内部结构的调整和技术发展水平的提高。结构调整方面，主要是企业结构向专业化调整，产品结构向着中高档模具发展，向进出口结构的改进，中高档汽车覆盖件模具成形分析及结构改进、多功能复合模具和复合加工及激光技术在模具设计制造上的应用、高速切削、超精加工及抛光技术、信息化方向发展。 近年，模具行业
45、结构调整和体制改革步伐加大，主要表现在，大型、精密、复杂、长寿命、中高档模具及模具标准件发展速度高于一般模具产品；塑料模和压铸模比例增大；专业模具厂数量及其生产能力增加；“三资”及私营企业发展迅速；股份制改造步伐加快等。从地区分布来看，以珠江三角洲和长江三角洲为中心的东南沿海地区发展快于中西部地区，南方的发展快于北方。目前发展最快、模具生产最为集中的省份是广东和浙江，江苏、上海、安徽和山东等地近几年也有较大发展。 虽然我国模具总量目前已达到相当规模，模具水平也有很大提高，但设计制造水平总体上落后于德、美、日、法、意等工业发达国家许多。当前存在的问题和差距主要表现在以下几方面：（1）总量供不应求
46、，国内模具自配率只有70%左右。其中低档模具供过于求，中高档模具自配率只有50%左右。 （2）企业组织结构、产品结构、技术结构和进出口结构均不合理 。我国模具生产厂中多数是自产自配的工模具车间（分厂），自产自配比例高达60%左右，而国外模具超过70%属商品模具。专业模具厂大多是“大而全”、“小而全”的组织形式，而国外大多是“小而专”、“小而精”。国内大型、精密、复杂、长寿命的模具占总量比例不足30%，而国外在50%以上。2004年，模具进出口之比为3.7:1，进出口相抵后的净进口额达13.2亿美元，为世界模具净进口量最大的国家。（3）模具产品水平大大低于国际水平，生产周期却高于国际水平 产品水
47、平低主要表现在模具的精度、型腔表面粗糙度、寿命及结构等方面。 （4）开发能力较差，经济效益欠佳，我国模具企业技术人员比例低，水平较低，且不重视产品开发，在市场中经常处于被动地位。我国每个模具职工平均年创造产值约合1万美元，国外模具工业发达国家大多是1520万美元，有的高达2530万美元，与之相对的是我国相当一部分模具企业还沿用过去作坊式管理，真正实现现代化企业管理的企业较少。 造成上述差距的原因很多，除了历史上模具作为产品长期未得到应有的重视，以及多数国有企业机制不能适应市场经济之外，还有下列几个原因： （1）国家对模具工业的政策支持力度还不够，虽然国家已经明确颁布了模具行业的产业政策，但配套
48、政策少，执行力度弱。目前享受模具产品增值税的企业全国只有185家，大多数企业仍旧税负过重。模具企业进行技术改造引进设备要缴纳相当数量的税金，影响技术进步，而且民营企业贷款十分困难。 （2）人才严重不足，科研开发及技术攻关投入太少，模具行业是技术、资金、劳动密集的产业，随着时代的进步和技术的发展，掌握并且熟练运用新技术的人才异常短缺，高级模具钳工及企业管理人才也非常紧张。由于模具企业效益欠佳及对科研开发和技术攻关重视不够，科研单位和大专院校的眼睛盯着创收，导致模具行业在科研开发和技术攻关方面投入太少，致使模具技术发展步伐不大，进展不快。 （3）工艺装备水平低，且配套性不好，利用率低，近年来我国机
49、床行业进步较快，已能提供比较成套的高精度加工设备，但与国外装备相比，仍有较大差距。虽然国内许多企业已引进许多国外先进设备，但总体的装备水平比国外许多企业低很多。由于体制和资金等方面的原因，引进设备不配套，设备与附件不配套现象十分普遍，设备利用率低的问题长期得不到较妥善的解决。 （4）专业化、标准化、商品化程度低，协作能力差，由于长期以来受“大而全”“小而全”影响，模具专业化水平低，专业分工不细致，商品化程度低。目前国内每年生产的模具，商品模具只占40%左右，其余为自产自用。模具企业之间协作不畅，难以完成较大规模的模具成套任务。模具标准化水平低，模具标准件使用覆盖率低也对模具质量、成本有较大影响，特别是对模具制造周期有很大影响。 （5）模具材料及模具相关技术落后，模具材料性能、质量和品种问题往往会影响模具质量、寿命及成本，国产模具钢与国外进口钢材相比有较大差距。塑料、板材、设备性能差，也直接影响模具水平的提高。 目前，我国经济仍处于高速发展阶段，国际上经济全球
