吹风机第五章总结展望参考文献附录

1、第五章 总结与展望5.1 总结通过对吹风机外壳注塑模具设计与制造，对常用塑料在成型过程中对模具的工艺要求有了更深一层的理解，掌握了塑料成型模具的结构特点及设计计算方法，对独立设计模具具有了一次新的锻炼。在设计过程充分利用了各种可以利用的方式，同时在反复的思考中不断深化对各种理论知识的理解，在设计的后一阶段充分利用cad软就是一例，新的工具的利用，大在提高了工作效率。本次毕业设计研究内容归纳如下：（1） 模具工业在国民经济中的我重要地位。（2） 分析了塑模设计和工艺分析原理及方法。（3） 利用solidworks研究吹风机的外形设计及塑模的模具设计。（4） 基于mastercam软件吹风机外壳注

2、塑模的数控加工及加工程序。在本次毕业设计我学到了许多知识，并为即将踏入社会的我奠定了坚实的基础。以下是我对这次的毕业设计的一些体会和心得： 这次毕业设计是一个理论与实践相结合的过程，这次设计教会了我发现问题时如何去解决它。解决问题的方法有很多，但是哪一个更合理这就要通过自己的计算了。本模具采用autocad、mastercam设计，在毕业设计其间对软件的理解与熟练程度得到了很好的提升。5.2 展望通过这次毕业设计，我还发现了自己的许多不足之处，比如想问题总是过于简单化，考虑不全面，爱钻死胡同，想到一个方案也不管是否合理就埋头苦算，到最后还是要改。另外本次设计有关于cae方面的知识相当欠缺，本次

3、设计也是一笔带过，并没有相关方面的实际操作，这一点是我们本次毕业设计的一个败笔，以后一定会充实这方面的知识，在今后的工作过程中我会做到扬长避短。设计时，经过不断的到校图书馆认真地查找和借阅相关的参考资料，不但提高了个人查阅资料的能力，还扩阔了我的知识视野。我想这些经历都会成为我将来的工作的宝贵经验。 致 谢本次毕业设计就像是一次挑战，没有了固定地点，没有固定的时间，没有老师全程的监督，完全把时间给我们去利用，开始独立的设计。通过本次毕业设计真的是让我获易良多，不仅大学三年所学的所有相关的专业知识得到了进一步的了解和巩固，而且还使我掌握了一些实际上机操作的知识，同时也提高了我对模具设计的综合能力

4、，培养了我独立运用所学的知识来解决实际问体的能力和信心。 在本次设计中我遇到了许多困难，但是黄伟玲老师、同组各位同学的指导、帮助与督促下，我都一一解决，在此表示衷心的感谢！尤其是xxx老师不厌其烦的给我指出错误，百忙之中对我言传身教，传授给我的不仅仅是全面系统的模具方面知识及机械各方面的知识，更包含了追求真理，严于律己、宽厚待人、助人为乐的优良品德。感谢我的同组同学，他们在本次毕业设计上给予我长期的支持和鼓励，与他们共同学习，共同分享期间的快乐。感谢所有曾经帮助过我的人。参考文献1 祁宏志.模具制造工艺m.北京：化学工业出版社,2009.2 齐晓杰.塑料成型工艺与模具设计m.北京：机械工业出版

12、tarts to make the mold and the use mold, but long-term has not formed 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 i

13、nvestments enterprise, the villages and towns (individual) the mold enterprises development also quite rapid .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,complex, the long l

14、ife mold domain. as a result of in aspect and so on mold precision, 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 ex

15、cept must continue to sharpen the productivity, from now on will have 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

16、upscale mold development, to the import and export structure improvement, 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

17、-speed cutting, the superfinishing and polished the technology, the information direction develops .the recent years, the mold profession structure adjustment and the organizational reform step enlarges, mainly displayed in, large-scale, precise, complex, the long life, center the upscale mold and t

18、he mold standard letter development speed is higher than the common 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 stoc

19、k system transformation step speeds up and so on. distributes from the area looked, take zhujiang 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 central

20、ized province is guangdong and zhejiang, places such as jiangsu, 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 manufac

21、ture horizontal overall rise and fall industry developed country 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 oneself rate only ,a

22、bout 70%. low-grade mold , center upscale mold assembling oneself rate 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 labo

23、r mold workshop which produces assembles oneself (branch factory), from 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 o

24、verseas mostly is small but, is specially small and fine. domestic large-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 t

25、he after net import volume to amount to 1.32 billion us dollars, is world 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 displa

26、y in the mold precision, cavity aspect and so on surface roughness, life and structure .(4) develops the ability badly, economic efficiency unsatisfactory.our country mold enterprise technical personnel proportion low the level is lower, also does not take the product development, frequently is in t

27、he passive position in the market. our country each mold staff average year creation output value approximately ,ten thousand us dollars, overseas mold industry developed country mostly 15 to 20 thousand us dollars, some reach as high as 25 to 30 thousand us dollars, relative is our country quite pa

28、rt of molds enterprises also continues to use the workshop type management with 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

29、which should have, as well as the most state-owned enterprises mechanism cannot 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 profess

30、ion industrial policy, but necessary policy few, carried out dynamics to be weak. 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 e

31、quipment 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 profess

32、ion 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 high-quality mold fitter and the enterprise management talent extremely is also an

33、xious. 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 income, causes the mold profession invests too few in

34、the scientific research development and the technical attack aspect, causes the mold technological development step not to be big, progresses not quick .(3) the craft equipment level to be low, also necessary is not good, the use factor low recent years our country engine bed profession progressed q

35、uickly, has been able to provide the quite complete precision work equipment, 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 ov

36、erseas many enterprises. as a result of aspect the and so on system and fund reason, introduces the equipment not 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

37、 for a long time .(4) specialization, standardization, commercialized degree low, 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.

38、 at present domestic every year produces mold, commodity mold minister 40% about, other for from produce uses for oneself. between the mold enterprise cooperates impeded, completes the comparatively large-scale mold complete task with difficulty. mold standardization level low, mold standard letter

39、use cave rare is low also to the mold quality, the cost has a more tremendous influence, specially has very tremendous influence .(5) to the mold manufacture cycle) the mold material and the mold correlation technology falls the mold material performance, the quality and the variety question often c

40、an affect the mold quality, the life and the cost, the domestically produced molding 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

41、 at the high speed development phase, on the international economical globalization 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 h

42、igh speed to develop, on the other hand, the mold manufacture also gradually will 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 mar

43、ket overall development tendency prospect will favor, estimated the chinese mold will 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 g

44、reat strides forward. 15 period, the chinese mold industry level not only has the 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 technolo

45、gy advancement aspect also can obtain a bigger development .the mold technology has 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 en

46、gineering. the mold technology development tendency mainly is the mold product to larger-scale, preciser, 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 info

47、rmation, is not having the chart, is fine, the automated direction develops, the mold enterprise to the technical integration, the equipment excellent, is producing approves the brand, the management information, the management internationalization direction develops. our country mold profession sti

48、ll will have to enhance from now on the general character technology had :(1) to establish in the cad/cae platform the advanced mold design technology, enhances modernization which the mold designed, information, intellectualization, standardized level .(2) establishes in the cam/capp foundation the

49、 advanced mold processing technology and the advanced manufacture technology unifies, raises the automated level and the production efficiency which the mold processes .(3) the mold production enterprises information management technology. for example pdm (product data management), erp (enterprise r

50、esource management), mis (mold manufacture management information system) and information network technology the and so on intermet platform application, the promotion and the development .(4) are high speed, gao jing, the compound mold processing technology research and the application. for example

51、 the ultra fine ramming mold manufacture technology, the precise plastic and the compression casting mold manufacture technology and so on .(5) enhances the mold production efficiency, reduces the cost and reduces the mold production cycle each kind of fast economical mold manufacture technology .(6

52、) the advanced manufacture technology application. for example hot technology and so on flow channel technology, gas auxiliary technology, hypothesized technology, nanotechnology, rapid scanning technology, reversion project, parallel project in the mold research, the development, the processing pro
