矩形罩盒注塑模具設計

1、I摘要本論文重點的分析和設計了矩形罩盒的塑料制品的模具設計基本過程。首先對國內模具發(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構；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、成型設備、一模幾腔等。此后便是選定分型面的基本位置，型芯結構的基本尺寸、型腔結構的基本尺寸、導向裝置的選取以及推出裝置的設

2、計分析，確定了定模板構件等各模板構件的基本厚度大小。設計出矩形罩盒的推出機構，包括推桿的確定和模的選擇等內容。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，確保矩形罩盒模具的可行性。關鍵詞：關鍵詞：工藝方案；模具結構；注塑機；模具設計AbstractAbstractThispapermainlyintroducesthedesignprocessoftheplasticmoldMinicomb.Firstgivesanov
