模具的發(fā)展趨勢
1．模具CAD/CAE/CAM正向集成化、三維化、智能化和網(wǎng)絡(luò)化方向發(fā)展
?? （1）模具軟件功能集成化
?? 模具軟件功能的集成化要求軟件的功能模塊比較齊全，同時各功能模塊采用同一數(shù)據(jù)模型，以實現(xiàn)信息的綜合管理與共享，從而支持模具設(shè)計、制造、裝配、檢驗、測試及生產(chǎn)管理的全過程，達到實現(xiàn)最佳效益的目的。如英國Delcam公司的系列化軟件就包括了曲面/實體幾何造型、復(fù)雜形體工程制圖、工業(yè)設(shè)計高級渲染、塑料模設(shè)計專家系統(tǒng)、復(fù)雜形體CAM、藝術(shù)造型及雕刻自動編程系統(tǒng)、逆向工程系統(tǒng)及復(fù)雜形體在線測量系統(tǒng)等。集成化程度較高的軟件還包括：Pro/ENGINEER、UG和CATIA等。國內(nèi)有上海交通大學(xué)金屬塑性成型有限元分析系統(tǒng)和沖裁模CAD/CAM系統(tǒng)；北京北航海爾軟件有限公司的CAXA系列軟件；吉林金網(wǎng)格模具工程研究中心的沖壓模CAD/CAE/CAM系統(tǒng)等。
?? （2）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。如Pro/ENGINEER、UG和CATIA等軟件具備參數(shù)化、基于特征、全相關(guān)等特點，從而使模具并行工程成為可能。另外，Cimatran公司的Moldexpert，Delcam公司的Ps-mold及日立造船的Space-E/mold均是3D專業(yè)注塑模設(shè)計軟件，可進行交互式3D型腔、型芯設(shè)計、模架配置及典型結(jié)構(gòu)設(shè)計。澳大利亞Moldflow公司的三維真實感流動模擬軟件MoldflowAdvisers已經(jīng)受到用戶廣泛的好評和應(yīng)用。國內(nèi)有華中理工大學(xué)研制的同類軟件HSC3D4.5F及鄭州工業(yè)大學(xué)的Z-mold軟件。面向制造、基于知識的智能化功能是衡量模具軟件先進性和實用性的重要標志之一。如Cimatron公司的注塑模專家軟件能根據(jù)脫模方向自動產(chǎn)生分型線和分型面，生成與制品相對應(yīng)的型芯和型腔，實現(xiàn)模架零件的全相關(guān)，自動產(chǎn)生材料明細表和供NC加工的鉆孔表格，并能進行智能化加工參數(shù)設(shè)定、加工結(jié)果校驗等。
?? （3）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)既有必要，也有可能。美國在其《21世紀制造企業(yè)戰(zhàn)略》中指出，到2006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。
2.模具檢測、加工設(shè)備向精密、高效和多功能方向發(fā)展
（1）模具檢測設(shè)備的日益精密、高效
?? 精密、復(fù)雜、大型模具的發(fā)展，對檢測設(shè)備的要求越來越高?，F(xiàn)在精密模具的精度已達2～3μm，目前國內(nèi)廠家使用較多的有意大利、美國、日本等國的高精度三坐標測量機，并具有數(shù)字化掃描功能。如東風(fēng)汽車模具廠不僅擁有意大利產(chǎn)3250mm×3250mm三坐標測量機，還擁有數(shù)碼攝影光學(xué)掃描儀，率先在國內(nèi)采用數(shù)碼攝影、光學(xué)掃描作為空間三維信息的獲得手段，從而實現(xiàn)了從測量實物→建立數(shù)學(xué)模型→輸出工程圖紙→模具制造全過程，成功實現(xiàn)了逆向工程技術(shù)的開發(fā)和應(yīng)用。這方面的設(shè)備還包括：英國雷尼紹公司第二代高速掃描儀(CYCLON SERIES2)可實現(xiàn)激光測頭和接觸式測頭優(yōu)勢互補，激光掃描精度為0.05mm，接觸式測頭掃描精度達0.02mm。另外德國GOM公司的ATOS便攜式掃描儀，日本羅蘭公司的PIX-30、PIX-4臺式掃描儀和英國泰勒·霍普森公司TALYSCAN150多傳感三維掃描儀分別具有高速化、廉價化和功能復(fù)合化等特點。
?? （2）數(shù)控電火花加工機床
?? 日本沙迪克公司采用直線電機伺服驅(qū)動的AQ325L、AQ550LLS-WEDM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。瑞士夏米爾公司的NCEDM具有P-E3自適應(yīng)控制、PCE能量控制及自動編程專家系統(tǒng)。另外有些EDM還采用了混粉加工工藝、微精加工脈沖電源及模糊控制(FC)等技術(shù)。
（3）高速銑削機床(HSM)
銑削加工是型腔模具加工的重要手段。而高速銑削具有工件溫升低、切削力小、加工平穩(wěn)、加工質(zhì)量好、加工效率高(為普通銑削加工的5～10倍)及可加工硬材料(<60HRC)等諸多優(yōu)點。因而在模具加工中日益受到重視。瑞士克朗公司UCP710型五軸聯(lián)動加工中心，其機床定位精度可達8μm，自制的具有矢量閉環(huán)控制電主軸，最大轉(zhuǎn)速為42000r/min。意大利RAMBAUDI公司的高速銑床，其加工范圍達2500mm×5000mm×1800mm，轉(zhuǎn)速達20500r/min，切削進給速度達20m/min。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0.01mm。

The modern mold semifinished materials widely have used the seeds casting technology, the so-called solid casting is (polystyrene PS either polymethacrylate PMMA) manufactures using the foam plastics replaces traditional the wooden mold or the metal pattern, after the modelling does not have to take out the model, then may the casting, under the foam plastics model high temperature liquid metal function, deflagrate the gasification but to vanish, the molten metal substitution original foam plastics model holds the position, after the condensation forms the casting. The solid casting has the following several kind of situations in the practical application.
(1) dry sands solid casting
Namely all does not do any cementing agent quartz sand modelling with 55-100 goal, spreads with EPS or the PMMA foam plastics manufacture model hangs the 0.2-1mm thick permeability good fireproof coating level, by enhances the casting superficially attractive fineness, prevented the fat sand or collapses the box.
(2) negative compactions casting
The negative compaction casting calls V law modelling. This technology is the use all does but does not have the cementing agent the quartz sand to make the molding sand, makes the model with EPS or the PMMA foam plastics, in under the plastic film seal condition, entire lets cast (vacuum degree 0.4-0.67MPa) carries on the liquid metal casting under the negative pressure condition, after the casting coagulates relieves the negative pressure then to obtain the superficial bright and clean casting.
(3) resins granulated substance solid casting
Makes the molding sand using the resin granulated substance, makes the model with EPS or the PMMA foam plastics, under the normal temperature, the atmospheric pressure carries on the liquid metal casting but to make takes the casting. uses the solid casting the technical manufacture mold semifinished materials to have the size precision high (the ISO9 level), processing remainder small (generally about 5mm), does not need to pull out the mold ascent, does not need the making core and the sand core brace, saves the metal material, economical makes the wooden model the lumber, the manufacture cycle short, the cost is low. This technology suits large-scale, is complex, the single unit mold semifinished materials production. the ceramics fine cast, lose the cerotin to cast and so on the technology are increasing the mold semifinished materials precision, reduce the processing man-hour, reduce the manufacture cycle, reduce aspect and so on cost also demonstrate its unique superiority.
7．other aspects technologies
In order to simplify the mold the structural design, reduces the mold cost, reduces the mold manufacture cycle, in domestic and foreign also successively appeared some other aspects new technology application, like trades the mold frame, the ramming unit, the cutting edge built-up welding quickly, inlays the block casting, the nitrogen spring and so on.
