鏡盒式計算器底蓋注塑模具設(shè)計

鏡盒式計算器底蓋注塑模具設(shè)計,盒式,計算器,注塑,模具設(shè)計 大學(xué)本科畢業(yè)設(shè)計說明書摘 要注塑成型是塑件生產(chǎn)最常用的方法之一。本設(shè)計通過注塑模具產(chǎn)品，利用實體模型測量產(chǎn)品的尺寸，對實體進(jìn)行建模，并對塑件的材料和塑件結(jié)構(gòu)進(jìn)行分析，并對塑件的模具進(jìn)行設(shè)計，包括塑件成品的設(shè)計、工藝參數(shù)的分析與計算、工作部分的設(shè)計、模具結(jié)構(gòu)的設(shè)計和加工方案的制定，確定塑件的最佳澆注位置，并通過實際情況進(jìn)行調(diào)整，從而得到對實際生產(chǎn)來說最合理的澆注位置。在確定模具型腔數(shù)目后，分析產(chǎn)品的氣穴、熔接痕、充填時間、充填結(jié)束時的體積溫度、流動前沿處的溫度、速度/時間轉(zhuǎn)換點壓力、充填結(jié)束時的壓力、注射位置處壓力等，可確定注塑模具的合理性。最后本運(yùn)用PROE 4.0及其EMX4.1模塊來完成模具整體設(shè)計工作。關(guān)鍵詞：模具設(shè)計；PROE4.0；IAbstractPlastic shaping be used in common for plastic products to manufacture.Basing on the actual plastic products of electric blanket, the designer uses the actual model to measure the product, creates a model for the actual product and making an analysis to the materials and structure of the product. Designs the plastic mould, including the design of plastic finished product, analysis and account of craft parameter, the design of work piece, mould structure and the processing project. The designer focuses on the design and account work of parting-surface and slide. Using the designer uses Moldflow Plastics Insight 6.1 to make an analysis of the product，deciding the best location. And making a increase Basing on actuality to get the best effect . After deciding the number of cavity for mold ，using Moldflow Plastics Insight 6.1 to make an analysis for air pocket，weld lines，fillingtime，bulk temperatures of sandouting，temperature at flow front，pressure at V/P switchover point，screen out pressure，pressure at injected location and so on， to sure the rationality of mould design. The last using Pro-Engineer4.0 and EMX4.1 module is applied to the whole design.Keywords： mould design；PROE4.0； plastic products of electric blanket目 錄引 言1第一章 設(shè)計任務(wù)與流程21.1畢業(yè)設(shè)計任務(wù)21.注塑模具設(shè)計的流程2第二章 塑件成品、注塑模具設(shè)計與構(gòu)型42.1 概述42.2 模具設(shè)計環(huán)境和應(yīng)用軟件42.2.1 PROE4.042.2.2 AutoCAD52.3零件的三維圖和二維工程圖建模52.3.1零件的立體圖建模52.3.2零件的二維工程圖繪制62.4塑件的基本數(shù)據(jù)62.4.1塑件塑料品種的確定62.4.2塑件材質(zhì)72.4.3塑件結(jié)構(gòu)分析92.4.4塑件體積與質(zhì)量92.4.5塑件圖及其尺寸公差102.4.6分型面及排氣形式的確定102.4.7型腔數(shù)的確定與型腔的分布11第三章 分析設(shè)計與計算113.1澆注系統(tǒng)的設(shè)計113.1.1主流道設(shè)計113.1.2 冷料穴設(shè)計123.2 成型方案133.2.1 成型部分的設(shè)計133.2.2 成型零部件結(jié)構(gòu)設(shè)計153.2.3 成型零部件工作尺寸計算163.2.4 型腔壁厚和底板厚度的計算173.3 導(dǎo)向機(jī)構(gòu)設(shè)計193.3.1 合模導(dǎo)向機(jī)構(gòu)193.4脫模機(jī)構(gòu)設(shè)計.203.4.1脫模力計算.203.4.2推桿脫模機(jī)構(gòu)設(shè)計.203.5冷卻系統(tǒng)的計算213.6模架形式及規(guī)格213.7設(shè)備的選擇與校核.223.7.1 注塑機(jī)的選擇.223.7.2 校核.243.7.3 其他.243.8 模具裝配圖與零件圖的繪制25結(jié) 論.26參 考 文 獻(xiàn)27謝 詞28附 圖323
