technology is playing a key role in nonferrous metal structure forming processes. Diecasting process’s features are the strength and hardness of die casting on high, thinwalled castings with plex shape can be cast, and the production is efficient. The diecasting die is the key for the process of die casting, its quality decides the quality and accuracy of castings, and the design of the diecasting die affects its quality and operating life directly. Therefore, designing the diecasting die is the key to technological progress。經(jīng)計(jì)算，推桿受力符合要求。模具整體尺寸為 560 315 459mm，符合所選壓鑄機(jī)安裝空間。根據(jù)鑄件的形狀特點(diǎn)、零件尺寸及精度，選定了合適的壓鑄機(jī)， 通過準(zhǔn)確的計(jì)算并查閱設(shè)計(jì)手冊(cè)，確定了成型零件以及模體的尺寸及精度，在材料的選取及熱處理要求上也作出了詳細(xì)說(shuō)明，并在結(jié)合理論知識(shí)的基礎(chǔ)上，借助于計(jì)算機(jī)輔助軟
