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。 then sketch the draft of the layout of cavity and choose an equal injection machine。 關(guān)鍵詞： 塑料；掛鉤座；注射模； Pro/Engineer； MoldFlowThe 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。此外，設(shè)計(jì)中大部分分析計(jì)算都依靠設(shè)計(jì)軟件進(jìn)行，手工需要完成的只是模具的結(jié)構(gòu)形式選擇及計(jì)算校核，從而把設(shè)計(jì)工作從以往復(fù)雜繁瑣的計(jì)算過程中解放出來(lái)，借助于 EMX， 大大縮短 了 模具設(shè)計(jì) 花費(fèi)在創(chuàng)建、定制和細(xì)化模架部件以及模具組件上的時(shí)間 ，并且其 3D 實(shí)體模型 也 隨
