This topic came from the technology capability of product, the structure of the mold embarks, the pours system, the injection molding system and the related parameter examination, the mold took shape the partial structures, the against system, the cooling system all had the detailed design, at the same time , the processing craft of the mold were simply established. Through the entire process of the design indicated this mold can achieve the processing craft which the plastic lid requested. Key words plastic mold lid mold 5 一 、 緒論 模具工業(yè)是制造業(yè)中的一項基礎(chǔ)產(chǎn)業(yè)，是技術(shù)成果轉(zhuǎn)化的基礎(chǔ)，同時本身又是高新技術(shù)產(chǎn)業(yè)的重要領(lǐng)域，在歐美等工業(yè)發(fā)達國家被稱為 “點鐵成金 ”的 “磁力工業(yè) ”。也就是設(shè)計一副注塑模具來生產(chǎn) 鼠標 塑件產(chǎn)品，以實現(xiàn)自動化提高產(chǎn)量。 1 XXXXX 大學(xué) 系 別 機電工程 系 班 級 機械制造與自動化 姓 名 學(xué) 號 課題名稱 鼠標 注塑模設(shè)計 指導(dǎo)老師 2021 年 4 月 25 日 2 目 錄 目錄 ................................................................................................................................ 2 摘要 ................................................................................................................................ 4 一 、緒論 ........................................................................................................................ 5 二、 概述 ........................................................................................................................ 7 三、塑件工藝分析 ....................................................................................................... 7 塑件材質(zhì)工藝性 ................................................................................................. 7 塑件工藝性分析 ............................................................................................... 8 成型工藝性 ......................................................................................................... 9 四、確定型腔數(shù)目 ....................................................................................................... 9 五、確定分型面 .......................................................................................................... 10 六、澆注系統(tǒng)的設(shè)計 ................................................................................................. 12 確定澆口形式及位置 ....................................................................................... 13 澆口的形式 ............................................................................................... 13 澆口的選擇要點 ....................................................................................... 13 側(cè)澆口尺寸 ............................................................................................... 13 初步設(shè)計主流道及分流道形式和尺寸 ........................................................... 14 主流道 ....................................................................................................... 14 分流道 ....................................................................................................... 15 型腔位置的排布 ............................................................................................... 16 七、確定型腔、型芯工作部分的尺寸 ..................................................................... 17 7． 1 成型零件工作尺寸的計算 ............................................................................ 17 八、模架的選用 .......................................................................................................... 20 初選注塑機 ....................................................................................................... 20 注射壓力和鎖模壓力 ....................................................................................... 21 注射壓力 ................................................................................................... 21 鎖模力 ..................................................................................................... 21 塑料注射機參數(shù) ............................................................................................... 22 選用標準模架 ................................................................................................... 23 注射噴嘴與模具主流道襯套 ........................................................................... 23 注塑機相關(guān)參數(shù)的校核 ................................................................................... 24 注塑壓力的校核 ...................................................................................... 24 鎖模力的校核 .......................................................................................... 24 模具與注塑機裝模部位相關(guān)尺寸的校核 .............................................. 24 開模行程和塑件推出距離的校核 ........................................................... 25 九、其它機構(gòu)設(shè)計 ..................................................................................................... 25 9． 1 冷料穴和拉料桿的設(shè)計 ................................................................................ 25 3 9． 2 排氣系統(tǒng)的設(shè)計 ............................................................................................ 26 9． 3 推件板推出機構(gòu)的設(shè)計 ................................................................................ 26
