【正文】 摘要本課題主要是針對圓蓋的注塑模具設計,該圓蓋材料為改性PS，是工業(yè)生產(chǎn)中常見的一種保護蓋產(chǎn)品。通過對塑件進行工藝的分析和比較,最終設計出一副注塑模。該課題從產(chǎn)品結(jié)構(gòu)工藝性，具體模具結(jié)構(gòu)出發(fā)，對模具的澆注系統(tǒng)、模具成型部分的結(jié)構(gòu)、側(cè)抽機構(gòu)、頂出系統(tǒng)、冷卻系統(tǒng)、注塑機的選擇及有關參數(shù)的校核都有詳細的設計，同時并簡單的編制了模具的加工工藝。通過整個設計過程表明該模具能夠達到此塑件所要求的加工工藝。根據(jù)題目設計的主要任務是圓蓋注塑模具的設計，也就是設計一副注塑模具來生產(chǎn)塑件產(chǎn)品，以實現(xiàn)自動化提高產(chǎn)量。針對塑件的具體結(jié)構(gòu)，該模具是點澆口的雙分型面注射模具。 在現(xiàn)代的模具設計生產(chǎn)中,通常運用UG軟件進行產(chǎn)品的3D圖形設計，UGMoldWizard 是 UG 系統(tǒng)的一個獨立的智能化設計注射模具的模塊,按照注射模具設計過程的一般順序來實現(xiàn)模具設計的整個過程。利用UG分析中的塑模部件驗證對制件分析，并設置脫模方向及型芯和型腔區(qū)域。依次利用UG注塑模向?qū)е械哪＞逤SYS、收縮率、工件、型腔布局、分型、模架標準件、澆口流道和冷卻等功能設計三維模具。并運用 UGMoldWizard 檢驗制件構(gòu)的合理性，以及注射模具結(jié)構(gòu)設計的可行性。最后由三維圖直接生成二維圖。關鍵詞:注塑模 圓蓋 側(cè)抽機構(gòu)ABSTRACTThe main topic covered for a round of injection mold design, the materials for Modified PS, is monly found in industrial production of a protective cover products. Through the process of plastic parts for analysis and parison, the final design of an injection mold. The product mix from technology issues, and specific mold structure of the casting mold system, mold forming part of the structure, side pumped body, top of the system, cooling system, the choice of injection molding machine and related calibration parameters are detailed design, at the same time and developed a simple process dies. Through the entire design process that the mold can be achieved by the plastic parts processing requirements. Designed in accordance with the subject39。s main task is to build a round plastic injection mold design, that is, the design of an injection mold to produce plastic products in order to achieve automation to increase production. Plastic parts for the specific structure of the mold is the runner double parting surface of injection mold. In the modern mold design and production, usually by using UG software products 3D graphic is an independent mode of UG system to design injection mold intelligently, which uses the basic knowledgeembedded theory to realize thewholemold designing process in a normal order of injectionmold designing ，mold ponents in the UGvalidation analysis on the parts，and set the parting direction and the core and cavity ，followed by the use of the Wizard of UG injection mold mold CSYS, the contraction rate of the workpiece, cavity layout, typing, mold standard parts, gate runner and cooling functions to design threedimensional use the UGMoldWizard to check the production the accuracy is with high characteristics of efficiency. Finally，threedimensional mold directly generate twodimensional diagram.Key words： Injection mold ；round cap ；side pumped body目 錄摘要 IABSTRACT II前 言 1第1章 塑料成型制件的工藝性 2 制件原料的工藝性 2 制件的結(jié)構(gòu)工藝性 2第2章 初步選擇注射機 4 成型前的準備 4 制品PS的注塑成型參數(shù) 4 塑件的形狀估算其體積和質(zhì)量 4 確定型腔數(shù)量 4 注射機有關參數(shù) 5 分型面選擇 5第3章 澆注系統(tǒng) 6 主流道的設計 6 6 分流道設計 7 澆口設計 7 流動比的校核 8 排溢系統(tǒng) 8第4章 成型零件設計 9 凹模 9 凸模和滑塊 9 型腔、型芯徑向尺寸 10 型腔深度和型芯高度尺寸 10 凹模側(cè)壁厚度和底板厚度的計算 11 合模導向結(jié)構(gòu)機構(gòu)設計 12 推出機構(gòu)的復位 13
