成品——收音機底蓋注塑模具設(shè)說明書

1、I摘要本論文重點的分析和設(shè)計了收音機底蓋的塑料制品的模具設(shè)計基本過程。首先對國內(nèi)模具發(fā)展狀況進行概述，提出未來模具行業(yè)的發(fā)展狀況，使用UG建模和CAD進行工程圖的繪制，是此次設(shè)計的重點之一。通過使用UG進行建模，了解整套模具最核心部分的大體結(jié)構(gòu)；然后對塑件的工藝性進行分析，在滿足經(jīng)濟性的條件下，確定各項參數(shù)，包括材料、成型設(shè)備、一模幾腔等。此后便是選定分型面的基本位置，型芯結(jié)構(gòu)的基本尺寸、型腔結(jié)構(gòu)的基本尺寸、導(dǎo)向裝置的選取以及推出裝置的

2、設(shè)計分析，確定了定模板構(gòu)件等各模板構(gòu)件的基本厚度大小。設(shè)計出收音機底蓋的推出機構(gòu)，包括推桿的確定和模的選擇等內(nèi)容。通過對各項參數(shù)的計算和校核，保證模具可以制造出來和正常使用，確保收音機底蓋模具的可行性。關(guān)鍵詞：關(guān)鍵詞：工藝方案；模具結(jié)構(gòu)；注塑機；模具設(shè)計AbstractAbstractThispapermainlyintroducesthedesignprocessoftheplasticmoldMinicomb.Firstgivesa
