1、华中科技大学硕士学位论文摘要压铸是避无余爨铸造,宦具有生产效率离、节约能源和原材料、成本低、适于大规模生产、铸传矮量好等一系到优点。浇注系绞推为聪铸摸的~个重要部分,其设计质量直接关系到聪铸模的好坏和服铸件的质量。常冒是雁铸大国,但目前我国模其生产水平还不荔,不辘漩是嚣凌压铸鼓发震熬嚣要≯本文在礤究参数他装配技术襄姆缝建撰技术的基础上,开展了压铸模浇淀系统的研究工作。营先,论文综述嚣蓠夔羚各国悉铸模壤凝,撬感了对压铸模实现计算掇壤爨设诗豹必要性和紧迫性。然后,在总结装配技术帮变形设计技术静基础上,论文分辑了燕铸模浇注系统翁常用特征,以及特征之间的层次
2、、位置和引用的关系,实现了特征和几何模型的表达。建立了篷铸模浇注系统特征瘁。论文解决了压铸模浇注系统cAD的一魑关键问题。针对压铸模浇注系统的特点,对歪祷模浇淀系统遗行了模块亿交澎设计链瑾。装配技术和变形设计方法麓模其cAD中常用的设计方法,本文采用了参数化装配技术和变形设计方法。最后,程理论研究的基础上,开发了压铸模浇注系统cAD软件,完成了模套设计、浇注系统设计、溢滤槽没计鞠组件搽作模块,利用该软件可方便完成压铸模浇注系统的设计。关键词:压礴模浇疰系统cAb特霰建模特征麾参数证设计变形设计≯f薹l华中科技大学硕士学位论文AbstractDieca
