矩形罩盒注塑模具設(shè)計(jì)

1、I摘要本論文重點(diǎn)的分析和設(shè)計(jì)了矩形罩盒的塑料制品的模具設(shè)計(jì)基本過(guò)程。首先對(duì)國(guó)內(nèi)模具發(fā)展?fàn)顩r進(jìn)行概述，提出未來(lái)模具行業(yè)的發(fā)展?fàn)顩r，使用UG建模和CAD進(jìn)行工程圖的繪制，是此次設(shè)計(jì)的重點(diǎn)之一。通過(guò)使用UG進(jìn)行建模，了解整套模具最核心部分的大體結(jié)構(gòu)；然后對(duì)塑件的工藝性進(jìn)行分析，在滿足經(jīng)濟(jì)性的條件下，確定各項(xiàng)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設(shè)

2、計(jì)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(jì)出矩形罩盒的推出機(jī)構(gòu)，包括推桿的確定和模的選擇等內(nèi)容。通過(guò)對(duì)各項(xiàng)參數(shù)的計(jì)算和校核，保證模具可以制造出來(lái)和正常使用，確保矩形罩盒模具的可行性。關(guān)鍵詞：關(guān)鍵詞：工藝方案；模具結(jié)構(gòu)；注塑機(jī)；模具設(shè)計(jì)AbstractAbstractThispapermainlyintroducesthedesignprocessoftheplasticmoldMinicomb.Firstgivesanov
