在討論注塑機(jī)設(shè)計(jì)之前，先要對(duì)國內(nèi)外的注塑機(jī)工業(yè)的狀況、注塑機(jī)工業(yè)的發(fā)展方向有一個(gè)比較清晰的了解，這也就使我們對(duì)本課題的意義有所了解。本文首先簡要介紹了注塑機(jī)行業(yè)的發(fā)展情況和今后的發(fā)展方向，其次就是對(duì)注射裝置的結(jié)構(gòu)設(shè)計(jì)，設(shè)計(jì)的內(nèi)容包括對(duì)液壓馬達(dá)的選擇，和對(duì)螺桿、料筒、噴嘴、料斗等的設(shè)計(jì)，同時(shí)還對(duì)注塑機(jī)的基本參數(shù)進(jìn)行了計(jì)算。
