1、畢業(yè)設(shè)計(jì)（論文）課題：盒蓋注塑模具設(shè)計(jì)課題名稱：＿＿＿＿＿＿＿系別：＿＿＿＿＿＿＿專業(yè)：＿＿＿＿＿＿＿班級：＿＿＿＿＿＿＿姓名：＿＿＿＿＿＿＿學(xué)號(hào)：＿＿＿＿＿＿＿指導(dǎo)老師：＿＿＿＿＿＿＿2012-4-128摘要塑料模具在當(dāng)今社會(huì)越來越廣泛的應(yīng)用，從電腦、手機(jī)、飲料、臺(tái)燈、水筆、水盆等方面應(yīng)用極其廣泛，可以說從我們的吃穿住行都離不開它。注射成形是成形熱塑件的主要方法，因此應(yīng)用范圍很廣。注射成形是把塑料原料放入料筒中經(jīng)過加熱熔化，使之成為高黏度的流體，用柱塞或螺桿作為加壓工具，使熔體通過噴嘴以較高壓
2、力注入模具的型腔中，經(jīng)過冷卻、凝固階段，而后從模具中脫出，成為塑料制品。本次的畢業(yè)設(shè)計(jì)是盒蓋注塑模的設(shè)計(jì)，該模具結(jié)構(gòu)簡單，成型分型都非常簡單。依據(jù)產(chǎn)品的數(shù)量和塑料的工藝性能確定了以單分型面注塑模的方式進(jìn)行設(shè)計(jì)。模具的型腔采用一模一腔，澆注系統(tǒng)采用直澆口成形，推出形式為推桿推出機(jī)構(gòu)完成塑件的推出。由于塑件的工藝性能要求注塑模中有冷卻系統(tǒng)，因此在模具設(shè)計(jì)中也進(jìn)行了設(shè)計(jì)。本次的設(shè)計(jì)中參考了大量的文獻(xiàn)，還在互聯(lián)網(wǎng)上查找資料，設(shè)計(jì)過程比較完整。關(guān)鍵詞：單分型面注射模具；ABS;塑料模具。28Abstrac
