鏡盒式計(jì)算器底蓋注塑模具設(shè)計(jì),盒式,計(jì)算器,注塑,模具設(shè)計(jì) 大學(xué)本科畢業(yè)設(shè)計(jì)說(shuō)明書(shū) 摘 要 注塑成型是塑件生產(chǎn)最常用的方法之一。本設(shè)計(jì)通過(guò)注塑模具產(chǎn)品，利用實(shí)體模型測(cè)量產(chǎn)品的尺寸，對(duì)實(shí)體進(jìn)行建模，并對(duì)塑件的材料和塑件結(jié)構(gòu)進(jìn)行分析，并對(duì)塑件的模具進(jìn)行設(shè)計(jì)，包括塑件成品的設(shè)計(jì)、工藝參數(shù)的分析與計(jì)算、工作部分的設(shè)計(jì)、模具結(jié)構(gòu)的設(shè)計(jì)和加工方案的制定，確定塑件的最佳澆注位置，并通過(guò)實(shí)際情況進(jìn)行調(diào)整，從而得到對(duì)實(shí)際生產(chǎn)來(lái)說(shuō)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(shí)間、充填結(jié)束時(shí)的體積溫度、流動(dòng)前沿處的溫度、速度/時(shí)間轉(zhuǎn)換點(diǎn)壓力、充填結(jié)束時(shí)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(lái)完成模具整體設(shè)計(jì)工作。 關(guān)鍵詞：模具設(shè)計(jì)；PROE4.0； I Abstract Plastic 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.
