The first analyzes the power plug cover parts of the process characteristics, material properties and molding characteristics and conditions, structure, process, etc., and select the molding equipment. Then introduced the power plug cover injection mold parting line selection, determining the number and arrangement of the cavity, focusing on the gating system, molded parts, clamping guide mechanism, pulling mechanism, fixed pitch typing institutions and cooling system design. And then select the standard mold and the mold material and injection machine process parameters check. Finally, the working principle of the mold described, as well as problems that may arise in the process of installation and missioning summarize, analyze, and gives the corresponding solution. This article discusses the charger shell threeplate injection mold structure, namely the gating system condensate material and parts emerge in different parting surface, using a fourchamber mold cavity layout, and finally the use of the push plate parts introduced. Keyword:Charger shell。Injection mould。Threepence mould。Gating system。Moulding mechanism 。 Space parting institutions 浙江水利水電學院畢業(yè)設計（論文） 4 目錄 1. 電源插頭上 蓋工藝性分析 ..................................................................................... 7 工藝性分析 ............................................................................................................. 7 塑件的結(jié)構(gòu)及成型工藝性分析 .............................................................................. 8 塑件的成型特性和條件 .......................................................................................... 8 塑件表面質(zhì)量分析 ................................................................................................. 9 ABS 成型塑件的主要缺陷及消除措施 .................................................................. 9 2. 電源插頭注塑模具的結(jié)構(gòu)設計 ........................................................................... 10 分型面位置的確定 ................................................................................................ 10 分型面的選擇 ........................................................................................................ 10 確定型腔數(shù)量及排列方式 .................................................................................... 11 模具結(jié)構(gòu)形式的確定 ............................................................................................ 12 確定模具基本結(jié)構(gòu) ............................................................................................... 12 3. 注射機型號的確定 ............................................................................................... 12 所需注射量的計算 ................................................................................................ 12 塑件質(zhì)量，體積計算 ......................................................................................... 12 澆注系統(tǒng)凝料質(zhì)量、體積的初步計算 ............................................................. 13 注射機 型號的選定 ................................................................................................ 13 型腔數(shù)量及注射機有關工藝參數(shù)的校核 ............................................................ 13 型腔數(shù)量的校核 ................................................................................................. 14 注射機工藝參數(shù)的校核 ..................................................................................... 15 安裝尺寸的校核 ................................................................................................. 16 開模行程和推出機構(gòu)的校核 ............................................................................. 16 模架儲存與注射機拉桿內(nèi)間距 校核 ................................................................ 17 4. 澆注系統(tǒng)形式和澆口的設計 ............................................................................... 17 主流道的設計 ........................................................................................................ 17 浙江水利水電學院畢業(yè)設計（論文） 5 主流道尺寸 ......................................................................................................... 18 主流道襯套的形式 ............................................................................................. 18 主流道襯套的固定 ............................................................................................. 19 冷料穴的設計 ........................................................................................................ 20 分流道的設計 ........................................................................................................ 20 澆口的設計 ............................................................................................................ 22 澆注系統(tǒng)的平衡 .................................................................................................... 23 澆注系統(tǒng)凝料體 積的計算 .................................................................................... 23 ............................................................... 24 5. 成型零件的結(jié)構(gòu)設計和計算 ................................................................................. 24 塑件的成型收縮率 ................................................................................................ 25 型腔型芯各尺寸的計算 ........................................................................................ 25 型腔零件的強度和剛度的校核 .............................................................
