引 言


本說(shuō)明書(shū)為機(jī)械塑料注射模具設(shè)計(jì)說(shuō)明書(shū)，是根據(jù)塑料模具手冊(cè)，上的設(shè)計(jì)過(guò)程及相關(guān)工藝編寫(xiě)的。本說(shuō)明書(shū)的內(nèi)容包括：目錄、畢業(yè)設(shè)計(jì)指導(dǎo)書(shū)、畢業(yè)設(shè)計(jì)說(shuō)明書(shū)、畢業(yè)設(shè)計(jì)體會(huì)、參考文獻(xiàn)等。
編寫(xiě)本說(shuō)明書(shū)時(shí)，力求符合設(shè)計(jì)步驟，詳細(xì)說(shuō)明了塑料注射模具設(shè)計(jì)方法，以及各種參數(shù)的具體計(jì)算方法，如塑件的成型工藝、塑料脫模機(jī)構(gòu)的設(shè)計(jì)。
本說(shuō)明書(shū)在編寫(xiě)過(guò)程中，得到老師、同學(xué)和工作中師傅們的大力支持和熱情幫助，在此謹(jǐn)以致意。
由于本人設(shè)計(jì)水平有限，在設(shè)計(jì)過(guò)程中難免有錯(cuò)誤之處，敬請(qǐng)各位老師批評(píng)指正。
