And through the pore simulation analysis software of deformation, filling, pouring gate, exhaust, cooling time, pressure and injection molding parameters such as analysis and optimization, forecasting products possible problems in the forming process. Through the mold design shows that the mold can achieve the quality of the mobile phone shell and processing requirements. Keywords: The mobile phone shell and plastic molding mold Injection mold Tunnel or submarine gate 目 錄 第 1 章 塑件的成型工藝性分析 ............................................... 1 塑件材料的選用與性能分析 ........................................... 1 材料的選擇 .................................................... 1 ABS 的性能分析 ................................................. 1 ABS 注射成型工藝參數(shù) .......................................... 2 ABS 成型塑件的主要缺陷及消除措施 .............................. 2 手機(jī)外殼塑件的測(cè)繪 .................................................. 3 手機(jī)外殼 塑件的二維圖 .......................................... 3 手機(jī)外殼塑件的三維圖 .......................................... 4 手機(jī)外殼塑件的結(jié)構(gòu)分析 .............................................. 6 結(jié)構(gòu)分析 ...................................................... 6 成型分析 ..................................................... 6 第 2 章 成型設(shè)備及模架的選用 ............................................... 7 確定型 腔數(shù)量及排列方式 .............................................. 7 模具結(jié)構(gòu)形式的確定 .................................................. 7 模架的選擇 .......................................................... 8 注塑機(jī)的選擇 ........................................................ 8 手機(jī)外殼塑件的計(jì)算 ............................................ 8 注塑機(jī)型號(hào)的初步確定 .......................................... 9 第 3 章 分 型面的選擇與澆注系統(tǒng)的設(shè)計(jì) ...................................... 10 確定型腔數(shù)量及排列方式 ............................................. 10 注射模分型面的選擇 ................................................. 10 澆注系統(tǒng)的設(shè)計(jì) ..................................................... 10 主流道的設(shè)計(jì) ................................................. 11 定位圈設(shè)計(jì) .................................................. 12 分流道設(shè)計(jì) ................................................... 12 澆口設(shè)計(jì) ..................................................... 14 第 4 章 成型零部件設(shè)計(jì) .................................................. 16 成型零部件的結(jié)構(gòu)設(shè)計(jì) ............................................... 16 成型零部件尺寸的計(jì)算 ............................................... 17 定模型腔尺寸計(jì)算 ............................................. 17 動(dòng)模 型芯尺寸計(jì)算 ........................................... 19 第 5 章 側(cè)向分型與抽芯機(jī)構(gòu) ................................................ 20 . 斜導(dǎo)桿的結(jié)構(gòu) ...................................................... 20 斜導(dǎo)桿的固定形式 ................................................... 21 第 6 章 合模導(dǎo)向、推出復(fù)位機(jī)構(gòu)設(shè)計(jì) ........................ 錯(cuò)誤 !未定義書簽。 合模導(dǎo)向機(jī)構(gòu)設(shè)計(jì) ................................................... 22 推出機(jī)構(gòu)的設(shè)計(jì) ................................................... 22 推桿設(shè)計(jì) .......................................................... 23 脫模力的計(jì)算 ....................................................... 24 第 7 章 模具冷卻 和排氣 系統(tǒng) 設(shè)計(jì) ......................................... 26 冷卻系統(tǒng)設(shè)計(jì) ...............................
