Injection molding is forming hot plastic pieces of main methods, so wide applications. The plastic injection molding is ingredients in a nitrogentreated barrel with heat of melting, make it bee the high viscosity fluid, with piston or screw as pressure tool, melt through the nozzle with higher injection mould cavity pressure, after cooling, coagulation phase, and then from the mold in decent shape, bee plastic products. The graduation design is blower of injection mould stent, the die structure simple, forming the parting quite simple. According to the number of products and plastic39。s process performance determined the parting surface in a single injection mold way design. The mould cavity use a module and four cavity balance layout, pouring system USES some gate forming, roll out form for push board launched institutions plastic parts to launch the finish. Because plastic parts of the process performance requirements of injection mold cooling system, and therefore in the mold design and design. The design of the reference of a large number of literature, and also in the Inter for material, design process is plete. Key words ： single injection mold parting surface。 ABS。 Plastic mould. 第 4 頁(yè) 共 39 頁(yè) 目錄 緒論 ............................................................................................... 6 1 塑料制件的工藝性分析及工藝結(jié)構(gòu)設(shè)計(jì) .......................................10 成型塑料制件結(jié)構(gòu)工藝性分析 ...........................................10 塑件材料的分析 ...............................................................12 ...................................................................14 3 注塑設(shè)備的選擇 .........................................................................15 估算塑件體積質(zhì)量 .............................................................15 選擇注塑機(jī) ......................................................................16 4 塑料件的工藝尺寸的計(jì)算 ...........................................................17 5 分型面的設(shè)計(jì) ............................................................................19 6 注塑機(jī)有關(guān)參數(shù)的校核 ..............................................................20 最大注塑量的校核 .............................................................20 注塑壓力校核 ..................................................................20 鎖模力的校核 ....................................................................21 模具與注塑機(jī)安裝部分相關(guān)尺寸校核 ................................21 開(kāi)模行程與頂裝置的校核 .................................................22 7 脫模機(jī)構(gòu)的設(shè)計(jì)與合模導(dǎo)向結(jié)構(gòu)設(shè)計(jì) ..........................................23 脫模力計(jì)算 ......................................................................23 脫模結(jié)構(gòu)設(shè)計(jì) ..................................................................23 脫模機(jī)構(gòu)的分類 ............................................................................23 脫模機(jī)構(gòu)的設(shè)計(jì)原則 .............................................................24 合模導(dǎo)向機(jī)構(gòu)的設(shè)計(jì) .........................................................26 8 澆注系統(tǒng)的設(shè)計(jì) ..........................................................................29 主流道設(shè)計(jì) ......................................................................29 分流道的設(shè)計(jì) ..................................................................29 分流道的布置 ....................................................................30 澆口的設(shè)計(jì) .......................................................................30 冷料穴的設(shè)計(jì) ..................................................................31 9 排氣系統(tǒng)和溫度調(diào)節(jié)系統(tǒng)的設(shè)計(jì) ................................................31 排氣系統(tǒng) .........................................................................31 溫度調(diào)節(jié)系統(tǒng)的設(shè)計(jì) ........................................................32 10 繪制裝配圖 ..............................................................................35 總結(jié) ..............................................................................................38 參考文獻(xiàn) .......................................................................................39 第 5 頁(yè) 共 39 頁(yè) 現(xiàn)成設(shè)計(jì)購(gòu)買(mǎi)注意事項(xiàng) 定做設(shè)計(jì)流程以及注意 第 6 頁(yè) 共 39 頁(yè) 緒論 1 國(guó)際國(guó)內(nèi)塑料成型模具發(fā)展概況 80 年代以來(lái)，在國(guó)家產(chǎn)業(yè)政策和與之配套的一系列國(guó)家經(jīng)濟(jì)政策的支持和引導(dǎo)下，我國(guó)模具工業(yè)發(fā)展迅速，年均增速為 13%， 2022 年我國(guó)模具工業(yè)產(chǎn)值為 375 億，至 2022 年我國(guó)模具總產(chǎn)值約為 525 億元，其中塑料模約 35%左右 。在未來(lái)的模具市場(chǎng)中，塑料模在模具總量中的比例還將逐步提高。 我國(guó)塑料
