能源、環(huán)境和安全是當(dāng)今備受關(guān)注的三大問題，也正是這三大問題制約了汽車工業(yè)的發(fā)展和汽車的普及。本文根據(jù)擠壓鑄造的工藝特點(diǎn)，對汽車輪轂擠壓鑄造模具 設(shè)計(jì) 進(jìn)行了分析總結(jié)，并對模具型腔進(jìn)行了結(jié)構(gòu)設(shè)計(jì)， 查閱模具設(shè)計(jì)手冊，完成模具的總體設(shè)計(jì)。s Degree The Structure of Automobile hub With Mold design Candidate： Specialty： Vehicle
