【正文】 can use the coating are: TiC, TiN, TiCN, TiAlN, CrN, Cr7C3, W2C, etc., while heat from the air treatment means to the development of vacuum heat treatment. In addition, the current strengthening of the laser, glow plasma Nitriding and electroplating (plating) enhanced anticorrosion technologies are also more and more attention. 5 mold industry new techniques, new ideas and new models have been gradually recognized In the forming process, the main function of posite stamping die, superplastic forming, plastic precision molding technology, plastic mold gasassisted injection technology and hot runner technology, highpressure injection molding technology. On the other hand, with the continuous development of advanced manufacturing technology and raise the level of mold industry as a whole, in the mold industry, there are some new design, production, management ideas and models. Concrete are: to adapt to the characteristics of moldpiece production flexible manufacturing technologies。s highspeed milling, the processing range of up to 2500mm 5000mm 1800mm, speed up 20500r/min, cutting feed speed of 20m/min. HSM generally used large, mediumsized mold, such as motor cover mold, die casting mold, large plastic surface machining, the surface precision up to . 3 rapid economic modeling techniques Shorten the product development cycle is an effective means of market petition to win one. Compared with the traditional mold process, fast economic modeling 8 technology is a short molding cycle, the characteristics of low cost, precision, and life can meet the production needs, overall economic efficiency is more significant in the mold manufacturing technology, specifically the following main technology. (1) rapid prototyping and manufacturing (RPM). It consists of threedimensional laser lithography (SLA)。具體主要有： 適應(yīng)模具單件生產(chǎn)特點(diǎn)的柔性制造技術(shù)；創(chuàng)造最佳管理和效益的團(tuán)隊精神，精益生產(chǎn)；提高快速應(yīng)變能力的并行工程、虛擬制造及全球敏捷制造、網(wǎng)絡(luò)制造等新的生產(chǎn)哲理；廣泛采用標(biāo)準(zhǔn)件通用件的分工協(xié)作生產(chǎn)模式；適應(yīng)可持續(xù)發(fā)展和環(huán)保要求的綠色設(shè)計與制造等。 4 模具材料及表面處理技術(shù)發(fā)展迅速 模具工業(yè)要上水平，材料應(yīng)用是關(guān)鍵。主要有鉍錫合金制模技術(shù)、鋅基合金制模技術(shù)、樹脂復(fù)合成形模具技術(shù)及硅橡膠制模技術(shù)等。 HSM 一般主要用 于大、中型模具加工，如汽車覆蓋件模具、壓鑄模、大型塑料等曲面加工，其曲面加工精度可達(dá) 。 數(shù)控電火花加工機(jī)床 日本沙迪克公司采用直線電機(jī)伺服驅(qū)動的 AQ325L、 AQ550LLSWEDM 具有驅(qū)動反應(yīng)快、傳動及定位精度高、熱變形小等優(yōu)點(diǎn)。 模具軟件應(yīng)用的網(wǎng)絡(luò)化趨勢 隨著模具在企業(yè)競爭、合作 、生產(chǎn)和管理等方面的全球化、國際化，以及計算機(jī)軟硬件技術(shù)的迅速發(fā)展，網(wǎng)絡(luò)使得在模具行業(yè)應(yīng)用虛擬設(shè)計、敏捷制造技術(shù) 2 既有必要，也有可能。 模具設(shè)計、分析及制造的三維化 傳統(tǒng)的二維模具結(jié)構(gòu)設(shè)計已越來越不適應(yīng)現(xiàn)代化生產(chǎn)和集成化技術(shù)要求。模具設(shè)計、分析、制造的三維化、無紙化要求新一代模具軟件以 立體的、直觀的感覺來設(shè)計模具，所采用的三維數(shù)字化模型能方便地用于產(chǎn)品結(jié)構(gòu)的 CAE 分析、模具可制造性評價和數(shù)控加工、成形過程模擬及信息的管理與共享。美國在其《 21 世紀(jì)制造企業(yè)戰(zhàn)略》中指出，到 2020 年要實現(xiàn)汽車工業(yè)敏捷生產(chǎn) /虛擬工程方案，使汽車開發(fā)周期從 40個月縮短到 4個月。瑞士夏米爾公司的 NCEDM 具有PE3 自適應(yīng)控制、 PCE 能量控制及自動編程專家系統(tǒng)。 3 3 快速經(jīng)濟(jì)制模技術(shù) 縮短產(chǎn)品開發(fā)周期是贏得市場競爭的有效手段之一。 (4)冷擠壓及超塑成形制模技術(shù)。因選材和用材不當(dāng)，致使模具過早失效，大約占失效模具的 45%以上。 5 Die trend CAD / CAE / CAM being integrated
