【正文】 湖北工業(yè)大學商貿(mào)學院畢業(yè)設(shè)計摘 要本次畢計業(yè)設(shè)的題目是：手機上殼的塑件注射模。本次設(shè)計主要是通過對塑件的形狀、尺寸及其精度的要求來進行注射成型工藝的可行性分析。塑件的成型工藝性主要包括塑件的壁厚，斜度和圓角以及是否有抽芯機構(gòu)。通過以上的分析來確定模具分型面、型腔數(shù)目、澆口形式、位置大??；其中最重要的是確定型芯和型腔的結(jié)構(gòu)，例如是采用整體式還是鑲拼式，以及它們的定位和固緊方式。此外還分析了模具受力，脫模機構(gòu)的設(shè)計，合模導(dǎo)向機構(gòu)的設(shè)計，冷卻系統(tǒng)的設(shè)計等。最后繪制完整的模具裝配總圖和主要的模具零件土及編制成型零部件的制造加工工藝過程卡片。關(guān) 鍵 詞 ： 分型面、澆口、型腔、型芯、鑲塊、脫摸力、潛伏澆口湖北工業(yè)大學商貿(mào)學院畢業(yè)設(shè)計IAbstract This graduate that design is:The movetelephone that shout the Battery door injects the design primarily passeses to piece viability assessment for request for of shape, size and its accuracy ing proceeding injecting type piece the wall for of type craft primarily including the piece is thick, slope and circle angle and whether to have corepulling or not the above analysis to e the certain molding tool cent the type the surface, type the number, gate the form, place the size。The among them and most important is a certain type core and the construction of the type , for example adopt the whole the type of type still , and their fixed position and tight way of .In addition and still analyzed the molding tool to suffer force, mold that design that the design of the pattern draw mechanism, match the design etc. to lead to the mechanism, cooling draw the production that plete molding tool assemble the general drawing sum the soil and establishment of prinipal molding tool parts type zero the parts process the craft process the card.Key phrase: parting line,the gate, cavity,core,mold insert, ejection force,submarinegate.湖北工業(yè)大學商貿(mào)學院畢業(yè)設(shè)計II目 錄摘 要 ......................................................................IABSTRACT ...................................................................II目 錄 ....................................................................III概 論 ......................................................................1第 1 章 塑件分析 .............................................................2第 2 章 塑件材料的成型特性與工藝參數(shù) .........................................3 塑件材料的特性 .........................................................3 成型特性 ...............................................................3 工藝參數(shù) ...............................................................3 塑料制件的結(jié)構(gòu)工藝性 ...................................................5 塑件在模具中的位置 .....................................................5第 3 章 設(shè)備的選擇 ...........................................................7 最大注射量 .............................................................7 注射量的校核 ...........................................................7 塑件在分型面上的最大注射量與鎖模力的校核 ...............................8 最大注射量的校核 ...................................................8 鎖模力的校核 .......................................................8 注射壓力的校核 .........................................................8 開模行程的校核 .........................................................8 注射機的技術(shù)規(guī)格 .......................................................9第 4 章 分型面與澆注系統(tǒng)的設(shè)計 ..............................................10 分型面的設(shè)計 ..........................................................10 主流道的設(shè)計 ..........................................................10 分流道的設(shè)計 ..........................................................11 澆口形式的選擇 ........................................................11 排溢系統(tǒng)的設(shè)計 ........................................................12第 5 章 零件工作部分尺寸計算 ...............................................13 成型零件的結(jié)構(gòu)設(shè)計 ....................................................13 成型工作零件的工作尺寸 ................................................13 型腔和型芯的徑向尺寸 ..............................................14 中心距尺寸 ........................................................16 型腔深度和型芯高度尺寸的計算 ......................................16 成型零部件的強度與剛度計算 ............................................17 進行成型零部件強度、剛度計算時考慮的要素 ..........................17 型腔的側(cè)壁和底板厚度的計算 ........................................18第 6 章 模架組合的選擇 ......................................................19湖北工業(yè)大學商貿(mào)學院畢業(yè)設(shè)計III第 7 章 合模導(dǎo)向機構(gòu)的設(shè)計 ..................................................20 導(dǎo)柱 ..................................................................20 導(dǎo)套 ..................................................................21第 8 章 推出與復(fù)位機構(gòu)的設(shè)計 ................................................22 推出機構(gòu)的組成 ........................................................22 推出機構(gòu)的設(shè)計原則 ....................................................22 脫模力的計算 ......................................................22 簡單推出機構(gòu) ..........................................................23 推桿位置的設(shè)置 ....................................................23 推桿的直徑 .
