摘要：本課題主要是針對(duì)兒童玩具積木的注塑模具設(shè)計(jì),材料為丙烯晴-丁二烯-苯乙烯（ABS），是工業(yè)生產(chǎn)中常見(jiàn)的一種產(chǎn)品。通過(guò)對(duì)塑件進(jìn)行工藝的分析和比較,最終設(shè)計(jì)出一副一模兩腔的注塑模具。該課題從產(chǎn)品結(jié)構(gòu)工藝性，具體模具結(jié)構(gòu)出發(fā)，對(duì)模具的澆注系統(tǒng)、模具成型部分的結(jié)構(gòu)、側(cè)抽機(jī)構(gòu)、頂出系統(tǒng)、冷卻系統(tǒng)、注塑機(jī)的選擇及有關(guān)參數(shù)的校核都有詳細(xì)的設(shè)計(jì)，同時(shí)并簡(jiǎn)單的編制了模具的加工工藝。通過(guò)整個(gè)設(shè)計(jì)過(guò)程表明該模具能夠達(dá)到此塑件所要求的加工工藝。根據(jù)題目設(shè)計(jì)的主要任務(wù)是兒童玩具積木注塑模具的設(shè)計(jì)，也就是設(shè)計(jì)一副注塑模具來(lái)生產(chǎn)塑件產(chǎn)品，以實(shí)現(xiàn)自動(dòng)化提高產(chǎn)量。
