家用電風(fēng)扇葉片注塑模具設(shè)計(jì)畢業(yè)設(shè)計(jì)

1、杭州電子科技大學(xué)本科畢業(yè)設(shè)計(jì)I摘要本論文闡述一套用于生產(chǎn)風(fēng)扇葉片的注塑模具設(shè)計(jì)，給定參數(shù)：風(fēng)扇直徑30CM，風(fēng)扇功率45W來進(jìn)行設(shè)計(jì)。設(shè)計(jì)時(shí)首先設(shè)計(jì)出塑件模型，然后選擇合適的材料，接下來再進(jìn)行模具設(shè)計(jì)（此次設(shè)計(jì)應(yīng)用ProE野火4.0版設(shè)計(jì)）。包括設(shè)計(jì)模具的成型系統(tǒng)、澆注系統(tǒng)、冷卻系統(tǒng)、導(dǎo)向系統(tǒng)、脫模系統(tǒng)等。設(shè)計(jì)的重點(diǎn)在于成型系統(tǒng)和澆注系統(tǒng)與脫模系統(tǒng)，而成型系統(tǒng)的重點(diǎn)在于分型面的設(shè)計(jì)，它決定了型芯和型腔結(jié)構(gòu)以及模具的質(zhì)量。因?yàn)樯热~塑件比較

2、特殊，葉片的厚度較薄，所以澆注系統(tǒng)澆口和主分流道的選擇顯得尤為重要。在設(shè)計(jì)中通過合理設(shè)計(jì)推出機(jī)構(gòu)和脫模機(jī)構(gòu)，保證了扇葉脫模時(shí)受力均勻，避免了葉片變形、扭曲。最后，通過選用合適的標(biāo)準(zhǔn)模架，設(shè)計(jì)出一套完整的模具。此外為保證設(shè)計(jì)合理，對(duì)注塑件進(jìn)行各種工藝仿真，提高了模具的設(shè)計(jì)效率！關(guān)鍵詞關(guān)鍵詞：風(fēng)扇葉片；注塑模具；ProE設(shè)計(jì)；分型面；成型系統(tǒng)；澆注系統(tǒng)杭州電子科技大學(xué)本科畢業(yè)設(shè)計(jì)III目錄第一章前言.....................
