摘  要

中國空調(diào)業(yè)的發(fā)展歷經(jīng)坎坷,從奢侈消費品飛入尋常百姓家,在實現(xiàn)了自身的巨大飛越之時,也見證了社會經(jīng)濟生活的巨大變遷。透過空調(diào)業(yè)二十多年來的發(fā)展,我們在親身感受著歷史的車輪由緩緩行駛步入飛速發(fā)展的大提速。
1978年,社會大眾對于空調(diào)的概念還局限于一部分特殊場合的重要物品。而進入1997年之后,隨著空調(diào)市場化運作的深入、人們生活水平的大幅提升,一大批在改革開放的春風(fēng)中先富裕起來的人群,開始將空調(diào)作為日常的家居用品使用。隨后,全國各大中城市的空調(diào)普及率大幅提升,而在長三角、珠三角等經(jīng)濟發(fā)達地區(qū),許多鄉(xiāng)鎮(zhèn)居民的空調(diào)消費量也在呈現(xiàn)逐年增長的勢頭。  
隨后,國內(nèi)居民家庭中的空調(diào)普及率穩(wěn)步提升,2003年全國30個城市居民家庭中空調(diào)的保有率達到了55.9%,和1998年相比,增長了15個百分點。上海、北京、廣州等超大規(guī)模城市居民的空調(diào)每百戶擁有率已經(jīng)達108%以上。
隨著空調(diào)業(yè)的發(fā)展中央空調(diào)控制器轉(zhuǎn)盤等這類空調(diào)的配套精密零件的制造成為我國現(xiàn)代空調(diào)業(yè)的一個重要組成部分。這些零件大部分需要用通過精密的模具來制造。
由于種種歷史原因,我國模具工業(yè)與當(dāng)前工業(yè)發(fā)展還不很適應(yīng)。無論是在設(shè)計制造技術(shù)和生產(chǎn)能力方面,還是在管理水平方面,模具工業(yè)均遠遠不能滿足需求,它嚴重影響工業(yè)產(chǎn)品的品種、質(zhì)量和生產(chǎn)周期,削弱了其在國際市場上的競爭能力。近年來,我國模具進口幅度呈大幅下降之勢,并有超億元出口額。大型、復(fù)雜、精密、高效和長壽命模具也逐年上新的臺階,體現(xiàn)高水平制造技術(shù)的級進模也越來越多,沖壓自動線、自動沖技術(shù)也得到廣泛應(yīng)用。我國模具行業(yè)的技術(shù)迅速提高,模具國產(chǎn)化已經(jīng)取得十分可喜的成績,這將對我國在國際市場的競爭能力和綜合國力的提高起到有力的促進作用。

ABSTRACT
The industry of Chinese Air Condition has been suffering a long time. It used to be a luxury machine and no one used it, but now it can be seen in almost every families. The developments of this industry not only raise its own value, but also witness the huge changes of the economy in our modern society. Though this development, we are just like putting our selves into the wheels which are continuously driving us to the success.    In 1978, the requirements to the air condition are just at a extremely low level. When it comes 1997, people's living standard increases dramatically. Lots of people are becoming richer than ever before. They can easily afford to all kinds of modern home appliance. The air condition which is one of the most famous one are being more and more used in normal lives. The reports said that in down areas, the percentage of people who have air condition is increasing sharply those years. Also in other sub urban areas, the consume on this machine also rises steadily every year.    During the following years, this development didn't stop. The statistics reveals that in 2003, the percentage of people who has been holding an air condition in 30 cities of all country has rated at 55.9%, which is 15 percent higher than that of 1998. In big cities like Shanghai 、Beijing and Guangzhou, this percentage even picked at more than 108%.    Also these developments of air condition make the manufacturing its parts such as Central air conditioning temperature controller turntable becoming an essential part to constitute our modern industry of air condition. These parts are mostly made by precise moulds.
Because of various history reason, molding industry of china and the industry develop now are still not adapt very much. Is in the aspects of designing to make the technique and produce the ability regardless, still manage the level aspect, the molding tool industry can't meet the demands all and far and far, the species, quantity and the production periods of its serious influence  industry product, weakened its competition ability in international market. In recent years, our country the molding tool imports the range to present to descend significantly, and have over hundred million dollar’s exit sum. Large, complications, nicety, the longevity life, also ascend the new step year by year with molding tool efficiently. More and more high manufacturing technique level’s progressive die has appeared. Hurtle to press the automatic line and hurtle the technique to also get the extensive application automatically. The technique of the molding tool profession of our country has developed very fast, the molding tool national product turn to have already very pleased result, it will let our country in the international market of exaltation of competition ability and comprehensive national strength rise to promote the function.
