【正文】 期,降低成本。由于我國(guó)的模具產(chǎn)品在國(guó)際市場(chǎng)上占有較大的價(jià)格優(yōu)勢(shì),因此對(duì)于出口前景好的模具產(chǎn)品也應(yīng)作為重點(diǎn)來(lái)發(fā)展。根據(jù)上述需要量大、技術(shù)含量高、代表發(fā)展方向、出口前景好的原則選擇重點(diǎn)發(fā)展產(chǎn)品,而且所選產(chǎn)品必須目前已有一定技術(shù)基礎(chǔ),屬于有條件、有可能發(fā)展起來(lái)的產(chǎn)品。 根據(jù)“十一五”模具行業(yè)發(fā)展規(guī)劃,“十一五”期間模具產(chǎn)品發(fā)展重點(diǎn)主要有如下幾類: (1)汽車覆蓋件模具沖壓模具占模具總量的40%以上。汽車覆蓋件模具主要為汽車配套,也包括為農(nóng)用車、工程機(jī)械和農(nóng)機(jī)配套的覆蓋件模具,它在沖壓模具中具有很大的代表性,模具大都是大中型,結(jié)構(gòu)復(fù)雜,技術(shù)要求高。尤其是為轎車配套的覆蓋件模具,要求更高,可以代表沖壓模具的水平。此類模具我國(guó)已有一定的技術(shù)基礎(chǔ),已為中檔轎車配套,但水平還不高,能力不足,目前滿足率只有一半左右。中高檔轎車覆蓋件模具主要依靠進(jìn)口,已成為汽車發(fā)展的瓶頸,極大的影響著車型開發(fā)。 (2)精密沖壓模具 多工位級(jí)進(jìn)模和精沖模代表了沖壓模具的發(fā)展方向,精度要求壽命要求極高,主要為電子工業(yè)、汽車、儀器儀表、電機(jī)電器等配套。這兩種模具,國(guó)內(nèi)已有相當(dāng)基礎(chǔ),并已引進(jìn)了國(guó)外技術(shù)及設(shè)備,個(gè)別企業(yè)生產(chǎn)的產(chǎn)品已達(dá)到世界水平,但大部分企業(yè)仍有較大差距,供應(yīng)總量不足,進(jìn)口很多。 (3)大型精密塑料模具 塑料模具占模具總量近40%,而且這個(gè)比例還在上升。塑料模具中為汽車和家電配套的大型注塑模具,為集成電路配套的塑封模,為電子信息產(chǎn)業(yè)和機(jī)械及包裝配套的多層、多腔、多材質(zhì)、多色精密注塑模,為新型建材及節(jié)水農(nóng)業(yè)配套的塑料異型材擠出模及管路和噴頭模具等,目前雖然已有相當(dāng)技術(shù)基礎(chǔ)并正在快速發(fā)展,但技術(shù)水平與國(guó)外仍有較大差距,總量供不應(yīng)求,每年的進(jìn)口額達(dá)幾億美元。 (4)主要模具標(biāo)準(zhǔn)件 目前國(guó)內(nèi)已有較大產(chǎn)量的模具標(biāo)準(zhǔn)件主要是模架、導(dǎo)向件、推桿推管、彈性元件等。這些產(chǎn)品不但國(guó)內(nèi)配套大量需要,出口前景也很好,應(yīng)繼續(xù)大力發(fā)展。氮?dú)飧缀蜔崃鞯涝饕揽窟M(jìn)口,應(yīng)在現(xiàn)有基礎(chǔ)上提高水平,形成標(biāo)準(zhǔn)并組織規(guī)?;a(chǎn)。 (5)其他高技術(shù)含量的模具 占模具總量給8%的壓鑄模具中,大型薄壁精密壓鑄技術(shù)含量高,難度大。鎂合金壓鑄模具目前雖然剛起步,但發(fā)展前景好,有代表性。子午線橡膠輪胎模具也是發(fā)展方向,其中活絡(luò)模技術(shù)難度最大。與快速成型技術(shù)相結(jié)合的一些快速制模技術(shù)及相應(yīng)的快速經(jīng)濟(jì)模具具有很好的發(fā)展前景。這些高技術(shù)含量的模具在“十一五”期間也應(yīng)重點(diǎn)發(fā)展。附錄B 外文文獻(xiàn)Mold design and manufacturing processAbstract:In recent years, due to the rapid development of China39。s manufacturing industry, and the stamping process in the manufacturing and use of unique features, stamping die design technology research increasingly by domestic concern and attention. The 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 longterm has not formed the industry. Straight stabs 0 centuries 8039。s later periods, the Chinese mold industry only then drives into the development speedway. Recent years, not only the stateowned mold enterprise had the very big development, the three investments enterprise, the villages and towns (individual) the mold enterprise39。s development also quite rapid .  The level of mold design and manufacturing technology, has bee the measure of an important symbol of national science and technology, to a large extent determine the quality, effectiveness, new product development capabilities, determine a country39。s international petitiveness of the manufacturing sector. 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 recent years, the mold profession structure adjustment and the organizational reform step enlarges, mainly displayed in, largescale, precise, was plex, the long life, center the upscale mold and the mold standard letter development speed is higher than the mon mold product.Keywords: die design manufacture;craftwork level 。die design manufacture。 die manufacturing;die precision;With the rapid development of the world economy, China39。s mold industry is developing rapidly. Mold is the basis of industrial production industries, in the automotive, electronics, mechanical and electrical, instrumentation, home appliances and telemunications industries, 60% 80% of the parts have to rely on forming mold. Cold stamping die in die play a rather important position, the scope of products affected, and about half of the total number of mold, so from all sides attach great importance to the quality of stamping parts and mixed with the mold to a large extent depend on the design, manufacture skills.The 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 longterm has not formed the industry. Straight stabs 0 centuries 8039。s later periods, the Chinese mold industry only then drives into the development speedway. Recent years, not only the stateowned mold enterprise had the very big development, the three investments enterprise, the villages and towns (individual) the mold enterprise39。s development also quite rapid .Although the Chinese mold industrial development rapid, but pares with the demand, obviously falls short of demand, its main gap concentrates precisely to, largescale, is plex, the long life 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 except must continue to sharpen the productivity, from now on will have emphatically to the profession internal structure adjustment and the stateofart 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 improvement, center the upscale automobile cover mold forming analysis and the structure improvement, the multipurpose pound mold and the pound processing and the laser technology in the mold design manufacture application, the highspeed 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, largescale, precise, was plex, the long life, center the upscale mold and the mold standard letter development speed is higher than the mon mold product。 The plastic mold and the pression 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 from the area looked, take Zhujiang Delta and Yangtze River delta as central southeast coastal are
