【正文】 塑料掛鉤座注射模具設(shè)計摘要注射模在機械、電子、航天航空、生物等領(lǐng)域及日用品的生產(chǎn)中得到了越來越廣泛的應(yīng)用，但我國的塑料成形模具設(shè)計整體水平還較低，跟發(fā)達國家有很大的差距，主要表現(xiàn)在：模具零件變形大、溢邊毛刺大、表面質(zhì)量差、模具型腔沖蝕和腐蝕嚴(yán)重、模具排氣不暢和型腔易損等。目前，我國的注射成型發(fā)展方向主要為提高大型、精密、復(fù)雜、長壽命模具的設(shè)計制造水平及CAD/CAE/CAM技術(shù)的應(yīng)用范圍。本設(shè)計的課題是塑料掛鉤座注射模具設(shè)計，塑件結(jié)構(gòu)復(fù)雜，尺寸精度要求較高，模具設(shè)計具有一定的難度。設(shè)計內(nèi)容分為以下三個方面：注射可行性分析、模具總體設(shè)計和模具零部件設(shè)計。整個設(shè)計過程主要借助PRO/ENGINEER（以下簡稱PRO/E）、MoldFlow等軟件完成。該模具設(shè)計的過程為：（1） 對塑件實體進行測繪，同時在PRO/E中創(chuàng)建其3D模型，并用PRO/E的模型分析功能對其進行初步分析和計算；（2） 擬定型腔布局并選擇合適的注射機；（3） 利用PRO/E的模具模塊完成模具的模仁設(shè)計和澆注系統(tǒng)設(shè)計，在設(shè)計澆注系統(tǒng)時，運用MoldFlow軟件對塑件進行了最佳澆口位置分析和注射模流分析及模擬；（4） 用PRO/E注塑模設(shè)計專家（簡稱EMX）進行模架和模具各零部件的設(shè)計。本設(shè)計的最大特點是運用先進的設(shè)計理念，在3D實體模型環(huán)境下完成整個模具設(shè)計過程。從零件建模，到模具結(jié)構(gòu)設(shè)計，以及最后的工程出圖，均通過PRO/E軟件完成；并且在設(shè)計過程中充分利用了PRO/E、MoldFlow的分析功能，進行了如澆注系統(tǒng)分析、注射模擬、開模動作檢測、干涉檢測等工作，以設(shè)計出最為合理的模具結(jié)構(gòu)。此外，設(shè)計中大部分分析計算都依靠設(shè)計軟件進行，手工需要完成的只是模具的結(jié)構(gòu)形式選擇及計算校核，從而把設(shè)計工作從以往復(fù)雜繁瑣的計算過程中解放出來，借助于EMX，大大縮短了模具設(shè)計花費在創(chuàng)建、定制和細化模架部件以及模具組件上的時間，并且其3D 實體模型也隨著設(shè)計零件的更改而自動更新，從而使設(shè)計周期大為縮短，較好的保證了該模具的設(shè)計水平。本設(shè)計較好的實現(xiàn)了利用先進CAD/CAE/CAM技術(shù)對該復(fù)雜、精密塑件的設(shè)計。關(guān)鍵詞：塑料；掛鉤座；注射模；Pro/Engineer；MoldFlow48 / 48The abstract of designing plastic pothook injection mouldThe injection mould has been more and more widely used in the field of machine, electronics, aviation, biology and modity. But the technology of designing injection mould in our country has a wide gap with developed countries due to paratively low average lever. The gap is mainly reflected in the following aspects: the large deformity of the part, the great burr of side overflow, the lower surface quality, the serious erosion and cauterization of the mould, the bad exhaust of mould and the easily destroyed of the cavity and so on. At present, the direction of our injection mold is focus on improving the technology of large, exact, plex and longlife mould and widening the range of using the CAD/CAE/CAM.The subject of the design is an injection mould for plastic pothook, as the configuration of the plastic is plex, and the precision of the dimension is high required, the design of the mould is difficult in some degree. The content of the design can be divided into three parts: the analysis of the injection possibility, the whole design of the mould and the design of the parts, the process have been finished chiefly with the help of software Pro/Engineer.The general processes of the design is: firstly, survey and draw the plastic, establish it’s 3D model by PRO/E。 then primarily analysis and figure up it using the analytic function of PRO/E。 then sketch the draft of the layout of cavity and choose an equal injection machine。 next, making use of PRO/E’s module to plete the design of core and cavity as well as molding system, on which, software MoldFlow is used to do the analysis of the best gate location and the analysis and simulation of fluid。 at last, use Expert Moldbase Extension of PRO/E to execution the designing of the moldbase and every part of the mould. The most conspicuous feature of the design is that the whole process is done in the environment of 3D model, which is conduct by the advanced theory. The software POR/E pletes the work from modeling to the design of construction, and the last draw for engineering. During the process, the analytic function of PRO/E、MoldFlow have been fully used to do the work, such as: Analysis of molding system, injection simulation, the testing of mold opening and interference and so on, in order to make the most rational mould. In addition, most analysis and count are finished by design software automatically, therefore, what left to be done by hand are only selecting the form of the mould、 calculate and check the result. In which condition, the fussy pute process can be avoided, and the time spent on creating, ordering and simplifying the parts and ponent part can be largely shortened with the help of EMX. The 3D model can renew itself automatically as the change of the design parts, therefore, the design circle can greatly be shortened and the mould quality can be better secured.Key words: plastic。 pothook。 injection mould。 Pro/Engineer。 MoldFlow目錄前言．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．Ⅰ設(shè)計說明書．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．１第一章 產(chǎn)品分析．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．１ 塑件分析．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．１ 塑件原材料分析．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．2第二章 擬定型腔布局.....．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．４ 型腔．．．．．．．．．．．．．．．．．．．．.．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．4 型腔數(shù)目的確定...．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．４ 型腔排布．．．．．．．．．．．．．．．．.．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．5第三章 塑件相關(guān)計算及注塑機的選擇．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．６ 塑件相關(guān)計算.．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．
