摘要本論文是根據(jù)實際的需要設(shè)計出骨輪的注射模。在設(shè)計中采用的是聚甲醛的塑料，成型的方式為一模兩腔，分析了產(chǎn)品的工藝性，確定了塑料的工藝參數(shù)和設(shè)計方案，以及它的總體結(jié)構(gòu)和具體結(jié)構(gòu)，并進行了一些必要的尺寸計算和強度校核。本文還對分型面、澆注系統(tǒng)、側(cè)抽芯機構(gòu)、頂出機構(gòu)、脫模機構(gòu)和溫度調(diào)節(jié)系統(tǒng)進行了分析設(shè)計，完成了模具三維設(shè)計和工程圖設(shè)計。通過設(shè)計，綜合應(yīng)用了大學(xué)期間的多數(shù)基礎(chǔ)和專業(yè)知識，加深所學(xué)知識體系，掌握了應(yīng)用 Pro\E 進行塑料模具的設(shè)計方法和技巧，熟悉了工程應(yīng)用設(shè)計。關(guān)鍵詞：注射模 塑料 成型 結(jié)構(gòu)設(shè)計AbstractThe present paper actual completes the plastic injection mould of gulun according to the practical necessary. Uses the POM plastic injection in the design to take shape, the formation way is a mold two cavities. The paper concretely studies product’s technology capability, and determines the formation equipment and the designing concept. Else, it determines the gross construction, each effective range concrete structure and carries on some essential size computation and the intensity examination. The paper also designs the halving-profile, the irrigate system, shuck institution, temperature adjust system and other systems. Finally, it completes the triaxiality models and the schedule drawings of the mould.Through this design, we have applied the university period most foundations and the specialized knowledge, deeply studies the knowledge system, have mastered the methods and skills of designing plastic mould with Pro\E, and have been familiar with the project application design.Keywords Plastic injection mould Plastic Forming structure design目 錄1 引言 .............................................................................................................11.1 塑料模具的現(xiàn)狀及發(fā)展 .............................................................................11.2 塑料注塑模具的設(shè)計步驟 ..........................................................................41.3 課程任務(wù)要求 ............................................................................................72 方案分析與設(shè)計 ...........................................................................................83 注塑成型的準備 ...........................................................................................93.1 注塑成型工藝簡介 .....................................................................................93.2 注塑機的選擇 ..........................................................................................113.3 注射模具分型面的選擇 ...........................................................................133.4 注射模具澆注系統(tǒng)的設(shè)計 ........................................................................143.5 注射模具成型零件和模體的設(shè)計 .............................................................183.6 注射模具的側(cè)抽芯機構(gòu) ...........................................................................233.7 注射模具的頂出機構(gòu)的設(shè)計 ....................................................................243.8 塑料注射模具的排氣設(shè)計 ........................................................................253.9 塑料注射模具的溫度調(diào)節(jié)系統(tǒng)設(shè)計 .........................................................253.10 模具結(jié)構(gòu)設(shè)計 ........................................................................................264 注射模加工工藝設(shè)計 ..................................................................................264.1 坯料確定 .................................................................................................274.2 模板的平面加工 ......................................................................................274.3 塑料注射模具型腔常用加工方法及設(shè)備 ..................................................284.4 成型零件加工 ..........................................................................................29結(jié)束語 .............................................................................................................30致 謝 .............................................................................................................31參 考 文 獻 ....................................................................................................33附錄：設(shè)計圖紙（另外裝訂）
