【正文】 erence books to plete, and it will be a longterm influence in the future in personal design ability, the ability to use the knowledge and so on. This mission will use the mould of up_cover to design. The explain, which is the most important, is the mould design flow and the programming of numerical control way. First, i will use to analyse the bases property of up_cover, arrange the work piece and then create the separable face. Secondly, the machine which use to inject will be ensure and check. After a several works, i will design the system of pouring, the construction of the mould, the demould facility, the cooling system...and the norm spare part. At last, the software() will be use to imitate the numerical control process, ensure the route of tool, the method to process and stimulate its procedures. When the procedures are plete, the assembly drawing, the main ponent drawing will be show at the back. 吉林大學珠海學院本科畢業(yè)論文 3 目錄 緒論 ..................................................................................................... 6 設(shè)計題目 ： ........................................................................................ 6 任務分析 ............................................................................................ 7 塑件塑料品種的確定和結(jié)構(gòu)工藝性 ................................................... 9 塑料品種的確定 ................................................................................ 9 ABS 塑料的性能 ................................................................................. 9 塑料精度 .......................................................................................... 10 塑件的表面粗糙度 .......................................................................... 10 分型面及型腔的設(shè)計 .......................................................................... 11 分型面選擇 ...................................................................................... 11 選擇模具分型面的九個基本原則： ....................................... 11 Up_Cover 塑件分型面的確定 ................................................. 11 生成分型面 ............................................................................... 12 型腔的確定 ...................................................................................... 12 凹模、凸模厚度尺寸設(shè)計 ................................................................. 13 注塑機的選擇 ..................................................................................... 16 注射機有關(guān)參數(shù)的校核 ................................................................... 18 6． 1 校核所選注塑機的最大注射量 .................................................... 18 6． 2 校核所選注塑機的鎖模力 ............................................................ 18 吉林大學珠海學院本科畢業(yè)論文 4 6． 3 校核所選注塑機的注塑壓力 ........................................................ 19 6． 4 確定所設(shè)計模具的閉合高度 ........................................................ 19 6． 5 校核模具安裝部分 ........................................................................ 19 6． 6 校核開模行程 ................................................................................ 20 澆注系統(tǒng)的設(shè)計 ................................................................................. 21 主流道的設(shè)計 .................................................................................. 21 分流道的設(shè)計 .................................................................................. 22 7． 3 冷料穴和拉料桿的設(shè)計 ................................................................ 23 7． 4 澆口的設(shè)計 .................................................................................... 23 澆口的形式： .......................................................................... 23 澆口的尺寸： .......................................................................... 24 排氣系統(tǒng)的設(shè)計 .............................................................................. 24 成型零件設(shè)計 ................................................................................... 26 結(jié)構(gòu)零部件的設(shè)計 ........................................................................... 27 注射模 標準模架的選擇 .................................................................. 27 支承零部件設(shè)計 .............................................................................. 29 墊塊選擇 .................................................................................. 29 動定模坐板 ............................................................................ 30 合模導向裝置 .................................................................................. 30 導柱導向機構(gòu) ........................................................................... 30 導套 .......................................................................................... 31 吉林大學珠海學院本科畢業(yè)論文 5 推桿、推板固定板 .......................................................................... 31 冷卻管道的設(shè)計 .............................................................................. 32 模架 ................................................................................................... 33 電極 ................................................................................................... 34 電極的設(shè)計 ..................................................................................... 34 1模具的數(shù)控加工 ............................................................................... 35 凹模的加工 ...................................................................................
