1、摘要本畢業(yè)設(shè)計(jì)說明書主要講述對手機(jī)后蓋進(jìn)行模具設(shè)計(jì)的過程。通過對塑件的工藝分析，設(shè)計(jì)出塑料模具。本論文首先簡單介紹了模具設(shè)計(jì)與分類，然后對產(chǎn)品材料性能作了介紹，并初步選擇注射機(jī)。本說明書還詳細(xì)敘述了模具結(jié)構(gòu)方案，包括確定分型面、成型零部件的結(jié)構(gòu)設(shè)計(jì)、斜頂內(nèi)抽芯機(jī)構(gòu)、脫模機(jī)構(gòu)、合模導(dǎo)向機(jī)構(gòu)、冷卻系統(tǒng)等等的設(shè)計(jì)過程。還有重要零件的工藝參數(shù)的選擇與計(jì)算。校核注射模與注射機(jī)的關(guān)系等。本設(shè)計(jì)主要是通過使用Pro/ENGINEER與AutoCAD完成裝配圖、零件圖。此次畢業(yè)設(shè)計(jì)綜合了大學(xué)四年來所學(xué)的專業(yè)知識(shí)，從而進(jìn)一步鞏固了模具設(shè)計(jì)方面的相關(guān)
