【正文】 式或外熱式熱流道裝置，少數(shù)單位采用具有世界先進(jìn)水平的高難度針閥式熱流道裝置，少數(shù)單位采用具有世界先進(jìn)水平的高難度針閥式熱流道模 具。氣體輔助注射成型技術(shù)的使用更趨成熟，如青島海信模具有限公司、天津通信廣播公司模具廠等廠家成功地在 29～ 34 英寸電視機(jī)外殼以及一些厚壁零件的模具上運(yùn)用氣輔技術(shù)，一些廠家還使用了 CMOLD 氣輔軟件，取得較好的效果。還能生產(chǎn)厚度僅為 的一模兩腔的航空杯模具和難度較高的塑料門窗擠出模等等。在大型模具方面已能生產(chǎn) 48 英寸大屏幕彩電塑殼注射模具、 大容量洗衣機(jī)全套塑料模具以及汽車保險(xiǎn)杠和整體儀表板等塑料模具；精密塑料模具方面，已能生產(chǎn)照相機(jī)塑料件模具、多型腔小模數(shù)齒輪模具及塑封模具。 Autocad 目 錄 摘 要 ..................................................................................................................... 1 Abstract ................................................................................................................ 2 第一章 前 言 ........................................................................................................ 5 、我國塑料模具的發(fā)展現(xiàn)狀 ............................................................................................ 5 、國外塑料模的發(fā)展?fàn)顩r ................................................................................................ 5 第二章 產(chǎn)品分析 .................................................................................................. 7 塑件工藝分析 ................................................................................................................ 7 設(shè)計(jì)塑件時(shí)必須考慮的幾個(gè)方面的問題 ........................................................... 7 尺寸和精度 ........................................................................................................... 7 塑件的形狀 ......................................................................................................... 7 材料分析 .......................................................................................................................... 8 第三 章 注射機(jī)的選擇 ........................................................................................ 10 估算塑件體積 : ............................................................................................................. 10 注射機(jī)的類型和規(guī)格 .................................................................................................... 10 注射機(jī)有關(guān)工藝參數(shù)的校對(duì) ........................................................................................ 11 第四章 模具整體設(shè)計(jì) ........................................................................................ 13 型腔數(shù)目的確定 ........................................................................................................... 13 分型面設(shè)計(jì) .................................................................................................................... 14 澆注系統(tǒng)設(shè)計(jì) ................................................................................................................ 16 主流道設(shè)計(jì) ......................................................................................................... 16 分流道設(shè)計(jì) .......................................................................................................... 16 進(jìn)料口設(shè)計(jì) .......................................................................................................... 17 模架的選用 .................................................................................................................... 20 成型零部件設(shè)計(jì) ............................................................................................................. 21 導(dǎo)向機(jī)構(gòu)的設(shè)計(jì) ............................................................................................................ 24 導(dǎo)柱 ........................................................................................ 錯(cuò)誤 !未定義書簽。 關(guān)鍵詞 ： 小型斜齒輪 ； 注射模 ； Autocad Abstract Injection molding is the main method of forming thermoplastic parts, so a wide range of applications. Injection molding is the plastic material into the barrel through the heating and melting, make it bee the high viscosity fluid, with piston or screw as pressure tool, cavity melt through the nozzle with high pressure injection mold, after cooling, solidification stage, and then ejected from the mould, a plastic products. This paper takes the small bevel gear as the object, the inject
