基于UG的電話機(jī)機(jī)座下蓋塑料模具設(shè)計與仿真分析
摘要：模具工業(yè)在國民經(jīng)濟(jì)中占有重要地位，其生產(chǎn)技術(shù)水平的高低，己成為衡量1個國家產(chǎn)品制造水平高低的重要標(biāo)志。為了進(jìn)行注塑過程的CAE模擬，本文先根據(jù)實物用UG軟件進(jìn)行實體建模，再用UG下的注塑模具向?qū)K進(jìn)行模具設(shè)計，最后對電話機(jī)底座殼體的前殼部的實體CAD模型進(jìn)行了有限元網(wǎng)格的劃分和修改。塑料熔體的充填、流動和模具的冷卻等是注塑過程中幾個重要的過程。在注塑過程中，各種工藝參數(shù)如壓力、溫度、時間等都是影響塑料制品質(zhì)量高低的重要因素。本文采用CAE軟件moIdflow對充填、流動和模具的冷卻等過程進(jìn)行了模擬分析。根據(jù)模擬分析結(jié)果，對注塑工藝參數(shù)進(jìn)行了修改和優(yōu)化，得出了比較合理的工藝參數(shù)，設(shè)計了電話機(jī)殼體的模具。

According to UG telephone machine the lower cover enjection Mold design and imitate true analysis
Abstract: Mold industry occupies an important place in the national economy. The level of the mold manufacturing techniquesh as become a significant symbol of national manufacturing. At the same time, this paper canvasses the CAE software1moldflow and its application in engineering. In order to apply the Moldflow, this paper enlarges the plastic materials database and establishes a local plastic materials database which lay a foundation of setting our own domestic one.For the mould plastics CAE analysis, this paper carrie son division and modification of the net of the computer’s fore element CAD model. The processes of the filling, flowing of the plastic melt and the cooling of the mould and so on are the more important process in the plastic injection. In t he process of the llastic injecting various kinds of craft parameters, such as pressure, temperature, time, etc... are several important factors of the quality level of influencing the plastic products. This paper has imitated this process with software moldflow of CAE. Setting from the result of imitating, the craft parameters are revised and optimized to moulding plastics, more rational craft parameters are drew from it.Setting from imitating the analysis result，the author designs the injection mould of the telephone1element.
