武汉科技大学毕业论文气压瓶盖毕业设计本文详细地阐述了气压瓶盖注射模具的设计过程。设计了注射模具中的各个系统，如浇注系统、导向与定位机构、侧向分型与抽芯机构，并对塑料材料性能进行了分析。根据塑件的产品数量要求，以及结构要求，该模具采用一模一腔。整个设计过程都是用Pro/E软件进行参数化设计，尤其是对其中的MPA(Moldflow Plastics Advisers)和EMX4.1插件的使用，使整个模具设计过程简单明了。利用MPA软件进行模流分析，为模具设计和成型工艺的指定提供参照依据。使用Pro/E软件设计成型零件以及非标零件，从而进行全方面的参数化设计，即对模具进行分模、生成元件、装配、试模、开模等设计。使用EMX4.1调用标准模架以及标准件，从而完成模具的整体设计。同时应用Pro.e可快捷的将三维图转化为二维工程图，直接指导生产。针对塑件的特点，本模具设计了侧抽芯滑块机构，也构成了本次模具设计的主要内容。关键词 ：注射模，参数化设计，侧抽芯和滑块，气压瓶盖ABSTRACTThis article has elaborated the injection mould design of the Air pressure bottle cover. Designed all system of the injecting mould .and orientating institution,side disparting modle and taking out core institution. Besides , analyzing materialcapabilities .Considing the number of the production and fabric requiring , the mould is one mould with one cavity .That die is injection moule adhibiting three side cores.The whole design processeses are all according to the foundation of the software of Pro/ E .Particularly being to the usage of the MPA( the Moldflow Plastics Advisers) and EMX4.1 plug-in,make the whole die designprocess simplification understand.Using MPA carries through model stream analysis.for mould design and type technology to offer reference basis; then using Pro-E to carries out moulding parts and unstandarding parts, according the whole Parameter melts to design,namely carrying through dividing mould,generation element and examination mould, open mould. In EMX, we can load the standard component and standard parts, at the same time we can use it turn from the picture of 3D for the picture of 2D,immediacily instruct production.Basising the characteristic of the mold, the moule design Side core slide .These things also constituted main contents of this die design.Key words ：Injection mould，Parameterization design，Side core and slide mrvhsnidm，Air pressure bottle coverConference is by Council party research decided held of once important Conference, main task is in-depth learning implement XI General Secretary series important speech especially on two learn a do learning education of important indicates spirit, according to Central, and provincial and municipal on in all members in the carried out learn Constitution Party rules, and Speech series, be qualified party members learn the deployment requirements of education, for me two education work arrangements, education and guidance directly under the works of party members and further strengthening the conviction in ideal, keeping faithful to the party and set up breeze upright, play, dare, to speed up water conservancy reform and development efforts to provide a strong organizational guarantee. Just now, the XX gay announced municipal water systems two is Fertilization system, units of the party organization in accordance with the implementation plan, paying careful attention to implementation. The following, according to the spirit of the Central, provincial and municipal party Committee, and conducted my municipal water system two study and education, I wish to make three points. A, and deep awareness carried out two learn a do learning education of important meaning party of 18 big yilai, to XI comrade for General Secretary of Central, around full strictly rule party made has series major deployment, played has a strictly rule party of combination fist, has carried out has party of mass line education practice activities, three strict three real topic education, for solution members cadres especially County at level above leaders exists of highlight problem, advance full strictly rule party up to has very important of role, tube party rule party lost of Yu wide, and Lost in the loose, soft-lost problem has been greatly improved, ranks the overall quality has been greatly improved.
