ZS900 注塑機(jī)設(shè)計(jì)1摘 要在成型加工中，注塑占有占有重要位置，其設(shè)備就是注塑機(jī)。本文著手設(shè)計(jì)一款注塑量為 180g 合模力為 900KN 的注塑機(jī)。本文首先簡(jiǎn)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，接著通過(guò)查閱資料分析國(guó)內(nèi)外注塑機(jī)特點(diǎn)，最終選定設(shè)計(jì)方案為臥式雙缸液壓馬達(dá)直接驅(qū)動(dòng)的往復(fù)螺桿式注塑機(jī)，其合模、移座及頂出均通過(guò)液壓缸實(shí)現(xiàn)，屬于全液壓式注塑機(jī)。設(shè)計(jì)的內(nèi)容包括對(duì)注塑部件的設(shè)計(jì)包括螺桿、料筒、噴嘴、料斗等，合模部件設(shè)計(jì)、液壓系統(tǒng)設(shè)計(jì)等等。最后使用 CAD 軟件繪制注塑機(jī)和注射裝置的裝配圖，并且選出典型零件畫(huà)出零件圖。關(guān)鍵詞： 注塑機(jī)，注射，合模，油缸AbstractIn the molding process, injection occupies an important place, their equipment is the injection molding machine. This paper set out to design an injection volume of 180g of 900KN clamping force injection molding machine. This article briefly describes the development and the future direction of the injection molding machine industry, followed by access to data analysis features of the injection molding machine at home and abroad, the final selection of the design is a horizontal cylinder hydraulic motor direct drive reciprocating screw injection molding machine, which mold, ejector seats and were moved by hydraulic cylinders to achieve, are fully hydraulic injection molding machine. Design elements include injection molded parts design includes screw, barrel, nozzle, hopper, mold component design, hydraulic system design, and so on. Final assembly drawing using CAD software and injection molding machine device and select the typical parts draw parts diagram.Keywords: Injection Molding Machines, Injection, Mold, CylinderZS900
