【正文】 ocess and the introduction, the first in China to C8812E mobile phone back cover design, determine the parting surface, gating system design, the choice of injection molding machine, and then to Pro/ selection of die set, check, etc., these processes are very detailed the cell phone back cover injection mold design process mainly USES the Peo/ modelling design and its related to mobile phone shell EMX die fast on the selection of die gating system using Moldeflow software mainly gate location optimization, cooling circuit optimization, injection pressure, and a series of auxiliary analysis, through these analysis can be design to improve design, a very large extent, save the design cycle, improve the this design, not only for injection mold design had a deeper understanding, also make learning knowledge was obtained. Keywords: injection mold, Pro/E, simulation processing， Moldflow 基于 Pro/E 的手機(jī)外殼模具設(shè)計(jì)與解析 3 目錄 摘 要 ..................................................................................................................... 1 Abstract..................................................................................................................... 2 1 前言 ..................................................................................................................... 1 模具工業(yè)在國(guó)內(nèi)外現(xiàn)狀及其重要性 ................................................................ 1 設(shè)計(jì)的目的及意義 ........................................................................................... 2 2 塑件成形工藝性分析 .......................................................................................... 4 手機(jī)后蓋分析 .................................................................................................. 4 塑件的材料性能 .............................................................................................. 5 塑件的工藝性能 .............................................................................................. 5 3 注塑機(jī)的確定 ..................................................................................................... 6 分型面的確定 .................................................................................................. 6 型腔的數(shù)量確定及排列方式 ........................................................................... 6 注塑機(jī) 的選擇 .................................................................................................. 8 4 澆注系統(tǒng)的設(shè)計(jì) ................................................................................................ 10 澆注系統(tǒng)的組成和設(shè)計(jì)原則 ......................................................................... 10 主流道的設(shè)計(jì) ................................................................................................ 10 分流道的設(shè)計(jì) ................................................................................................ 11 澆口的設(shè)計(jì) .................................................................................................... 12 排氣方式設(shè)計(jì) ................................................................................................ 13 型腔、型芯的結(jié)構(gòu)設(shè)計(jì)和固定方式 .............................................................. 14 型腔、型芯工作尺寸計(jì)算 ............................................................................. 14 型腔側(cè)壁和底板厚度計(jì)算 ............................................................................. 15 動(dòng)模墊板厚度 ................................................................................................ 16 基于 Pro/E 的手機(jī)外殼模具設(shè)計(jì)與解析 4 5 脫膜機(jī)構(gòu)的設(shè)計(jì) ................................................................................................ 17 推出機(jī)構(gòu) ........................................................................................................ 17 分型原理 ........................................................................................................ 17 脫膜力計(jì)算 .................................................................................................... 17 推桿尺寸計(jì)算 ................................................................................................ 18 合模導(dǎo)向機(jī)構(gòu)設(shè)計(jì) ......................................................................................... 18 定位圈的設(shè)計(jì) ................................................................................................ 18 復(fù)位機(jī)構(gòu)設(shè)計(jì) ................................................................................................ 19 冷卻系統(tǒng)的設(shè)計(jì) ............................................................................................ 19 6 校核 ................................................................................................................... 21 注射壓力機(jī)的校核 ......................................................................................... 21 鎖模力的校核 ................................................................
