【正文】 ding technology. (4) cold extrusion mold technology and ultramolded shapes. (5) multipoint forming technology. (6) KEVRON steel blanking blanking tooling. (7) mold blank rapid manufacturing technology. Mainly dry sand Mold Casting, Va cuum Mold Casting, Resin Sand Mold Casting Lost Wax Casting, and other technologies. (8) Other aspects of technology. Such as the use of nitrogen gas spring pressure side, discharge, quick die technology, stamping unit technology, and cutting edge technology and solid surfacing edge inserts die casting technology. 4 mold materials and surface treatment technology developed rapidly Industry to the level of mold, material application is the key. Due to improper selection and use of materials, causing premature die failure, which accounts for more than 45% failure die. In the mold material, monly used cold work tool steel with CrWMn, Cr12, Cr12MoV and W6Mo5Cr4V2, flame hardened steel (such as Japan, AUX2, SX105V (7CrSiMnMoV), etc.。 by the general diffusion to the CVD, PVD, PCVD, ion peration , the direction of ion implantation, etc.。 extensive use of standard parts mon parts of the division of work mode of production。 to create the best management and effective teamwork, lean production。 used a prehardened plastic mold steel (such as the . P20), agehardening steel (such as the . P21, Japan NAK55, etc.), heat treatment hardened steel (such as the United States, D2, Japan, PD613, PD555, Sweden wins the White 136, etc.), powder die steel (such as Japan KAD18 and KAS440), etc.。 laminated profile manufacturing (LOM)。s PIX30, PIX4 desktop scanner and the United Kingdom Taylor Hopson39。 5 Die trend CAD / CAE / CAM being integrated, threedimensional, intelligent and work direction (1) mold software features integrated Die software features of integrated software modules required relatively plete, while the function module using the same data model, in order to achieve Syndicated news management and sharing of information to support the mold design, manufacture, assembly, inspection, testing and production management of the entire process to achieve optimal benefits. Series such as the UK Delcam39。另外，目前對(duì)激光強(qiáng)化、輝光離子氮化技術(shù)及電鍍 (刷鍍 )防腐強(qiáng)化等技術(shù)也日益受到重視。因選材和用材不當(dāng)，致使模具過(guò)早失效，大約占失效模具的 45%以上。主要有干砂實(shí)型鑄造、負(fù)壓實(shí)型鑄造、樹(shù)脂砂實(shí)型鑄造及失蠟精鑄等技術(shù)。 (4)冷擠壓及超塑成形制模技術(shù)。 (2)表面成形制模技術(shù)。 3 3 快速經(jīng)濟(jì)制模技術(shù) 縮短產(chǎn)品開(kāi)發(fā)周期是贏得市場(chǎng)競(jìng)爭(zhēng)的有效手段之一。因而在模具加工中日益受到重視。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(dòng)編程專家系統(tǒng)。這方面的設(shè)備還包括：英國(guó)雷尼紹公司第二代高速掃描儀 (CYCLON SERIES2)可實(shí)現(xiàn)激光測(cè)頭和接觸式測(cè)頭優(yōu)勢(shì)互補(bǔ)，激光掃描精度為 ，接觸式測(cè)頭掃描精度達(dá) 。美國(guó)在其《 21 世紀(jì)制造企業(yè)戰(zhàn)略》中指出，到 2020 年要實(shí)現(xiàn)汽車工業(yè)敏捷生產(chǎn) /虛擬工程方案，使汽車開(kāi)發(fā)周期從 40個(gè)月縮短到 4個(gè)月。國(guó)內(nèi)有華中理工大學(xué)研制的同類軟件 Zmold軟件。模具設(shè)計(jì)、分析、制造的三維化、無(wú)紙化要求新一代模具軟件以 立體的、直觀的感覺(jué)來(lái)設(shè)計(jì)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(píng)價(jià)和數(shù)控加工、成形過(guò)程模擬及信息的管理與共享。 畢業(yè)設(shè)計(jì)（論文）外文翻譯 外 文
