3531 套筒注塑模設(shè)計,套筒,注塑,設(shè)計 河南機電高等專科學(xué)校畢業(yè)設(shè)計說明書（套筒注塑模）摘要分析了 PA1010 塑料的特性及其對注塑工藝的影響，介紹了套筒注塑模主要零部件的尺寸計算方法，注塑模結(jié)構(gòu)及工作過程。根據(jù)套筒零件的特點確定了注塑模結(jié)構(gòu)，并且模具結(jié)構(gòu)設(shè)計精巧，達(dá)到了塑件的尺寸精度。針對塑件脫模過程中的難點，設(shè)計了一種非常規(guī)抽芯的注塑模結(jié)構(gòu)，并對模具設(shè)計與制造中的一些關(guān)鍵問題加以詳述。由于該模具需要 3 個方向抽芯，因此選擇了多種側(cè)向分型機構(gòu)，并對其中之一作了重點介紹，同時對澆注系統(tǒng)，頂出機構(gòu)也作了簡要說明。實踐證明，該模具設(shè)計合理，動作可靠，對同類塑件的注塑模設(shè)計有一定的參考價值。關(guān)鍵詞：PA1010 塑料 ;注塑模 ；設(shè)計 ；套筒 ；抽芯機構(gòu)；側(cè)向抽芯。 河南機電高等專科學(xué)校畢業(yè)設(shè)計說明書（Design of the Cylindrical bush Injection Mould）AbstractThe properties of the PA1010 plastics and their influences to the moulding technology are analyzed. The structure and working process of the cylindrical bush injection mould are introduced.And the dimension calculations for some key components of the mould are stated.Thestructure of the injection mould for the cylindrical bush has been determined according to it’s characteristics . The design of the mould structure is smart and the operation of the mould is easy. The plastic parts moulded with the mould have reached the required dimension precision .According to the difficulty in the plastic part demoulding process ,an injection mould with non-tradional core-pulling mechanism has been designed. And some key points in design and manufacture of the mould are stated in detail. Since the mould requires core-pulling on three directions ,various side parting mechanisms have been used and one of them is mainly introduced .The feed system and the ejector mechanism are briefly introduced . Practices show that the mould are design is reasonable and the mould movement is reliable. It can serve as a reference to the design of the moulds for similar parts.Key words:PA1010plastic;injection mould; design;Cylindrical bush;core-pulling;side parting.河南機電高等?？茖W(xué)校畢業(yè)設(shè)計說明書產(chǎn)品型號 零（部）件圖 號 凹模機械加工工藝過程卡片 產(chǎn)品名稱 零（部）件名稱共（1）頁第（1）頁材料牌號 40Cr毛坯種類板料 毛坯外型尺寸H50× B450每個毛坯可制件數(shù) 1每臺件數(shù) 1 備注工時工序號 工序名稱 工 序 內(nèi) 容車間 工段 設(shè)備工 藝 裝 備 準(zhǔn)終 單件01 鍛造 消除毛坯組織缺陷，改善其力學(xué)性能。 空氣錘 鉗子、卡尺 0.25h02 退火改善毛坯的切削加工性及消除熱加工的組織缺陷。煤氣爐鉗子8h03 銑削進行粗加工，留精加工余量及研磨量。銑床 夾具、卡尺 0.504 鏜凹模 孔 鏜床 坐標(biāo)鏜床 6h05 電火花加工加工凹模腔 電火花成型機夾具 尺子 0.5h06 調(diào)質(zhì) 達(dá)到零件各項力學(xué)性能要求。 調(diào)質(zhì)爐 鉗子 12h07 磨削 進行精加工，留研磨量。 加工中心 夾具、卡尺 5h08 研磨進行研磨使得零件達(dá)到零件圖上各項要求。砂布 千分尺 20h09 檢驗 對零件進行復(fù)查 0.5h設(shè)計日期標(biāo)記記數(shù)更改文件號簽字 日期 標(biāo)記 處數(shù)更該文件號審核日期標(biāo)準(zhǔn)化日期會簽日期河南機電高等?？茖W(xué)校畢業(yè)設(shè)計說明書
