【正文】 I 塑料把手模具設(shè)計(jì) 摘 要 近年來(lái),我國(guó)家電工業(yè)的高速發(fā)展對(duì)模具工業(yè),尤其是塑料模具提出了越來(lái)越高的要求, 2021 年,塑料模具在整個(gè)模具行業(yè)中所占比例已上升到 30%左右,據(jù)有關(guān)專家預(yù)測(cè),在未來(lái)幾年中,中國(guó)塑料模具工業(yè)還將持續(xù)保持年均增長(zhǎng)速度達(dá)到 10%以上的較高速度的發(fā)展。國(guó)內(nèi)塑料模具市場(chǎng)以注塑模具需求量最大,其中發(fā)展重點(diǎn)為工程塑料模具。 注射成型是塑料成型的一種重要方法,它主要適用于熱塑性塑料的成型,可以一次成型形狀復(fù)雜的精密塑件。本課題就是將塑料蓋作為設(shè)計(jì)模型,將注射模具的相關(guān)知識(shí)作為依據(jù),闡述塑料注射 模具的設(shè)計(jì)過(guò)程。 本設(shè)計(jì)對(duì)塑料蓋進(jìn)行的注塑模設(shè)計(jì),對(duì)塑件結(jié)構(gòu)進(jìn)行了工藝分析。明確了設(shè)計(jì)思路,確定了注射成型工藝過(guò)程并對(duì)各個(gè)具體部分進(jìn)行了詳細(xì)的計(jì)算和校核。如此設(shè)計(jì)出的結(jié)構(gòu)可確保模具工作運(yùn)用可靠,保證了與其他部件的配合。最后用AutoCAD 繪制了一套模具裝配圖和零件圖。 本課題通過(guò)對(duì)塑料蓋的注射模具設(shè)計(jì),鞏固和深化了所學(xué)知識(shí),取得了比較滿意的效果,達(dá)到了預(yù)期的設(shè)計(jì)意圖 關(guān)鍵詞: 塑料模具,注射成型,模具設(shè)計(jì) !!所有下載了本文的注意:本論文附有 CAD 圖紙和完整版說(shuō)明書(shū),凡下載了本文的讀者請(qǐng)留下你的聯(lián)系 方式( 郵箱),或加我百度用戶名 ,我把圖紙發(fā)給你。最后,希望此文能夠幫到你! II Medical plastic injection mold design cap ABSTRACT In recent years, China39。s household electrical appliance industry in the development of highspeed tooling industry, especially the plastic mold to the growing demands, in 2021, plastic mold in the mold industry in the proportion had increased to about 30 percent, according to relevant experts predict, In the next few years, China plastic mold industry will continue to maintain an average annual growth rate reached over 10 percent of high speed development. The domestic market to mold plastic injection mold the demand is greatest, of which focus on the development of engineering plastics mold. Plastic injection molding is an important method of molding, which apply mainly to the thermoplastic plastic molding, can be a plex shape of the precision molding plastic parts. This issue is the plastic cover as a design model, the injection moldrelated knowledge as the basis on the design of plastic injection molding process. The design of plastic injection mold covered the design, structure of the plastic parts of the process. Defined the design, determine the injection molding process and the specific part of a detailed calculation and verification. So the str ucture can be designed to ensure that the use of reliable mold work to ensure that the coordination with other ponents. Finally, AutoCAD drawing a mold assembly and parts plans. The topics covered by plastic injection mold design, consolidated and deepened by knowledge, has been relatively satisfied with the results, achieved the expected design intent KEY WORDS: Plastic mold, Inljection molding。 Die design III 目 錄 前 言 ....................................................................................................... 1 第 1 章 材料 ............................................. 5 設(shè)計(jì)要求 ................................................................................... 5 材料 ................................................................................... 5 塑件形狀分析 .................................................................. 5 第 2 章 初選注射機(jī) ....................................... 8 計(jì)算塑件體積 ............................................................................. 8 選擇壓力機(jī) ....................................................................... 8 確定型腔數(shù)目 .................................................................. 9 第 3 章 模具設(shè)計(jì) ...................................................................................11 型腔的分布 ................................................................................11 分型面的確定 .................................................................11 澆口的確定 ......................................................................11 澆注系統(tǒng)的確定 ....................................................................... 12 主流道 ............................................................................. 12 澆口套的設(shè)計(jì) ................................................................ 13 分流道的設(shè)計(jì) ............................................................. 14 冷料穴的設(shè)計(jì) ................................................................ 14 型腔型芯和型芯的確定 ......................................................... 15 型腔的結(jié)構(gòu)和固 定 ........................................................ 15 型芯的結(jié)構(gòu)和固定 ........................................................ 15 成型零部件的設(shè)計(jì) .................................................................. 16 型腔壁厚和底板厚度的計(jì)算 ........................................ 16 成型零件工作尺寸的計(jì)算 ............................................ 17 模架的選用 ............................................................................... 21 模具高度尺寸的確定 .................................................... 21 結(jié)構(gòu)零部件的設(shè)計(jì) ................................................................... 22 墊塊的設(shè)計(jì) ..................................................................... 22 IV 定模座板和動(dòng)模座板的設(shè)計(jì) ........................................ 22 導(dǎo)向與定位機(jī)構(gòu) ............................................................ 23 導(dǎo)套的設(shè)計(jì) ..................................................................... 24 推出機(jī)構(gòu)的設(shè)計(jì) ....................................................................... 25 推桿的設(shè)計(jì) ..................................................................... 26 結(jié) 論 .............................................. 29 謝 辭 ............................................... 29 參考文獻(xiàn) ............................................ 30 1 前 言 模具是工業(yè)生產(chǎn)的基礎(chǔ)工藝裝備。振興和發(fā)展我國(guó)的模具工業(yè),日益受到人們的重視和關(guān)注。在電子、汽車(chē)、電機(jī)、電器、儀器、儀表、家電和通訊等產(chǎn)品中, 60~ 80%的零部件,都要依靠模具成形。用模具生產(chǎn)制件所表現(xiàn)出來(lái)的高精度、高復(fù)雜程度、高一致性、高生產(chǎn)率和低消耗,是其他加工制造方法所不能比擬的。模具又是 “ 效益放大器 ” ,用模具生產(chǎn)的最終產(chǎn)品的價(jià)值,往往是模具自身價(jià)值的幾十倍、上百倍。模具生產(chǎn)技術(shù)水平的高低,已成為衡量一個(gè)國(guó)家產(chǎn)品制造水平高低的重要標(biāo)志,在很大程度上決定著產(chǎn)品的 質(zhì)量、效益和新產(chǎn)品的開(kāi)發(fā)能力。鑒于振興我國(guó)模具工業(yè)的重要性,在 1989 年 3 月國(guó)務(wù)院頒布的《關(guān)于當(dāng)前產(chǎn)業(yè)政策要點(diǎn)的決定》中,把模具列為機(jī)械工業(yè)技術(shù)改造序列的第一位、生產(chǎn)和基本建設(shè)序列的第二位。 1997 年以來(lái),國(guó)家又相繼把模具及其加工技術(shù)和設(shè)備列入了《當(dāng)前國(guó)家重點(diǎn)鼓勵(lì)發(fā)展的產(chǎn)業(yè)、產(chǎn)品和技術(shù)目錄》和《鼓勵(lì)外商投資產(chǎn)業(yè)目錄》。經(jīng)國(guó)務(wù)院批準(zhǔn),從 1997 年到 2021 年,對(duì)全國(guó)部分重點(diǎn)專業(yè)模具廠實(shí)行增值稅返還 70%的優(yōu)惠政策,以扶植模具工業(yè)的發(fā)展。 1999 年 7月國(guó)家計(jì)委和科學(xué)技術(shù)部發(fā)布的《當(dāng)前國(guó)家優(yōu)先發(fā)展的高新技術(shù)產(chǎn)業(yè)化 重點(diǎn)領(lǐng)域指南 (目錄 )》,把電子專用工模具、塑料成形新技術(shù)與新設(shè)備、快速原型制造工藝及成套設(shè)備、激光加工技術(shù)及成套設(shè)備、汽車(chē)關(guān)鍵零部件等等,都列進(jìn)去了。 1999 年 8 月 20日黨中央和國(guó)務(wù)院發(fā)布的《關(guān)于加強(qiáng)技術(shù)創(chuàng)新發(fā)展高科技實(shí)現(xiàn)產(chǎn)業(yè)化的決定》指出:要在電子信息特別是集成電路設(shè)計(jì)與制造、網(wǎng)絡(luò)及通訊、計(jì)算機(jī)及軟件、數(shù)字化電子產(chǎn)品等方面,在生物技術(shù)及新醫(yī)藥、新技術(shù)、新能源、航天航空、海洋等有一定基礎(chǔ)的高新技術(shù)產(chǎn)業(yè)領(lǐng)
