【正文】 超小型及高精度由于塑料應(yīng)用的擴(kuò)大，塑料制件已應(yīng)用到建筑、機(jī)械、電子、儀器等各工業(yè)領(lǐng)域。如高效冷卻以縮短成型周期；各種能可靠地自動(dòng)脫出產(chǎn)品和流道凝料的脫模機(jī)構(gòu)；熱流道澆注系統(tǒng)注射模具等。尤其是擠出機(jī)頭的設(shè)計(jì)，這使擠出制品產(chǎn)量和質(zhì)量都得到很大的提高。 近年來，塑料成型加工機(jī)械和成型模具增長十分迅速，高效率、自動(dòng)化、大型、微型、精密、高壽命估整個(gè)模具產(chǎn)量中所占的比例越來越大。在精度方面，塑件的尺寸精度可達(dá)IT67級(jí)。氣體輔助注射技術(shù)已成功得到應(yīng)用。一般均采用內(nèi)熱式或外熱式熱流道裝置。在精密塑料模具方面，能生產(chǎn)多型腔小模數(shù)齒輪模具和600腔塑封模具， 較高的塑料門窗擠出模等。在大型塑料模方面，已能自行生產(chǎn)34〃大屏幕彩電塑殼模具，6kg大容量洗衣機(jī)全套塑料模具及汽車保險(xiǎn)杠和整 體儀表板等的塑料模具。關(guān)鍵詞： CAD 、CAM、注塑模abstractIt is to design the drawer injection mould, references to the traditional mechanical design, focus on the CAD/CAM application in the plastic mould design, that is to say to apply the CAD system in model and plastic injection mould design. This artic introduces the mould technology and the CAD/CAM application of mould in china nowadays, Including PRO/E，AUTOCAD，MASTERCAM. While main mechanical designs content the principle and application of the plastic mould, design standards and brief intro of the items. The calculation of the plastic mould design concerns about the mould construction design, choosing injection machine, injection system and so on..Keywords: CAD CAM INJECTION MOULD 抽屜注塑模具設(shè)計(jì)機(jī)械設(shè)計(jì)制造及其自動(dòng)化，第1章緒論 我國塑料成型模具的現(xiàn)狀與發(fā)展趨勢(shì) 塑料成型模具是應(yīng)用得最為廣泛的一類模具。而主要的機(jī)械部分設(shè)計(jì)，其內(nèi)容包括塑料注塑模具的工作原理及應(yīng)用，設(shè)計(jì)準(zhǔn)則，以及產(chǎn)品的簡介。目 錄中英文摘要..............................................................3第1章 緒論............................................................4 我國塑料成型模具的現(xiàn)狀與發(fā)展趨勢(shì)...................................4 何謂注塑成型.......................................................5 CAD/CAM 的技術(shù)現(xiàn)狀.................................................5 使用微機(jī)作為開發(fā)和應(yīng)用平臺(tái)...................................6 PDM 技術(shù)的實(shí)施...............................................6 逆向工程...........................................................7第2章 CAD/CAM 軟件簡介................................................7 PRO/E 簡介.........................................................7 AUTOCAD 簡介.......................................................7 MASTERCAM 簡介.....................................................8第3章 模型的設(shè)計(jì)......................................................8 3D 模型的建立......................................................8 零件模具的設(shè)計(jì).....................................................9第4章 模具的裝配.....................................................11第5章 零件材料的選擇及材料性能 ....................................11 制品的材料選擇依據(jù)................................................11 聚苯乙烯的化學(xué)和物理特性....................................11 聚苯乙烯主要技術(shù)指標(biāo)........................................11 分析計(jì)算..........................................................12第6章 塑料注射成型模具的設(shè)計(jì).........................................13 注射機(jī)類型的選擇..................................................13 注射機(jī)有關(guān)工藝參數(shù)的校核..........................................13 注射量的校核................................................13 鎖模壓力的校核..............................................13 注射壓力的校核 ...........................................14 注射速率....................................................14 模具閉合厚度的校核..........................................14第7章 成型零件的設(shè)計(jì).................................................14 型腔分型面的設(shè)計(jì)..................................................14 排氣槽的設(shè)計(jì)......................................................14 成型零件的設(shè)計(jì)....................................................15 凹模的結(jié)構(gòu)設(shè)計(jì)..............................................15 型芯結(jié)構(gòu)設(shè)計(jì)................................................15 成型零件工件尺寸............................................16 復(fù)位機(jī)構(gòu)的設(shè)計(jì)....................................................16 塑件脫模機(jī)構(gòu)的設(shè)計(jì)................................................17 脫模力計(jì)算........................................................17 側(cè)向分型與抽芯機(jī)構(gòu)設(shè)計(jì)............................................17 斜導(dǎo)柱.....................................................17 導(dǎo)柱傾斜角的計(jì)算...........................................18 抽心距的計(jì)算...............................................18 斜導(dǎo)柱工作部分長度..........................................18 抽拔力的計(jì)算...............................
