【正文】 本設(shè)計特征要求，由于塑料件是程中心對稱，故采有整體式模體，且根據(jù)零件的處形特征，其三維形狀如圖36所示：定位圈的三維設(shè)計根據(jù)設(shè)計要求，定位圈的設(shè)計形狀如圖37所示：圖35圖36 圖373． 澆口套的三維設(shè)計 澆口套的三維形狀如圖38所示： 圖385． 型芯和滑塊滑塊用來側(cè)抽芯的，使模件形成側(cè)孔，且使斜導柱沿其孔運動。導柱：2022625 —84導套：3090（B）—846. 脫模機構(gòu)在注射成形的每一個環(huán)節(jié)中，塑件必須由模具型腔中脫出，脫出塑件的機構(gòu)稱為脫模機構(gòu)或頂出機構(gòu)。頂桿是頂出機構(gòu)最常見的一種結(jié)構(gòu)形式。頂桿與頂出固定板的連接形式采用墊板固定支撐連接。動畫模塊可以實現(xiàn)以下功能：1．將產(chǎn)品的運行用動畫來表示，使其具有可視性。2．可以用動畫的方式形象的表示產(chǎn)品的裝配和拆卸序列。 動畫創(chuàng)建的一般過程UG軟件三維動畫是在三維零件造型的基礎(chǔ)之上創(chuàng)建的，三維動畫能給人以直觀的視覺，讓人了解設(shè)計的運動過程。由于三維動畫的創(chuàng)建過程比較復雜繁瑣，難于在有限的篇幅里將創(chuàng)建過程敘述清楚，故省略了動畫的制作過程，其運動過程在視頻中播放。千萬不要刪除行尾的分節(jié)符，此行不會被打印。 42 結(jié) 論隨著塑料工業(yè)的發(fā)展，塑料注射模已經(jīng)成為制造塑料制品的主要手段之一，且發(fā)展成為最有前景的模具之一,而且我對模具也有著濃厚的興趣。 在為期20周的設(shè)計過程中，通過老師的引導和自己收集資料，初步的了解了模具行業(yè)的相關(guān)知識；比較系統(tǒng)的學習了注射模具設(shè)計的流程，包括模具材料的選擇、注射機的選擇、模具的各個部分如成型部分等的設(shè)計。它使我深深的體會到：在掌握好專業(yè)知識的同時，在計算機這個平臺上對模具進行設(shè)計、裝配、分析等將是模具行業(yè)發(fā)展的一個必然趨勢，兩者缺一不可。與此同時，由于實踐經(jīng)驗的缺乏，在模具的設(shè)計過程中可能會出現(xiàn)一些錯誤，懇請各位老師同學批評和指正。并在設(shè)計學會了簡單零件塑料的設(shè)計，并對UG軟件的運用更加熟練，還學到許多新的功能，得到了這個很好的鍛煉自己的機會。參考文獻1 朱光力，萬金保 等. 塑料模具設(shè)計. 北京：清華大學出版社，20032 李海梅，申長雨. 注塑成型及模具設(shè)計實用技術(shù). 北京：化學工業(yè)出版社，20053 ：機械工業(yè)出版社，20044 孫玉芹，孟兆新. ：科學出版社，20045 ：高等教育出版社，20026 ，20047 林清安.

The excellent technological properties of the workpiece and reasonable technology scheme would cut down the material exhausted, operation number and production time. It would also simplify the die construction and increase the die life, thus resulting in reducing the manual labour and the cost of the workpiece. The latter two factors are the main indexes for judging the design of the blanking process.1. Calulation of blanking force and methods to decrease blanking force(1) calculation of blanking forceThe purpose of the calculation of the blanking force is to choose a suitable press machine,to design the die,and to check the die strength . the ton capacity of the press machine should be higher than the blanking force.(2) hods to decrease blanking forceIn practice, in order to meet the demand of the equipment condition,and to reduce vibration and noise,following methods are used to decrease the blanking force.1) Blanking with heatin. The shearing strength of material can be significantly decreased when heated,so to decrease the blanking force. The disadvantage of this method is that a layer of oxide would be produced on the surface of the material after heating,and the working condition getting worse. Consequently,this method is only used with thick plate or the workpiece without high deamands on suface quality and tolerance grage.2) Multipunch stepped blanking. If there is more than one punch in blanking, the bottom surface of the plunch edge can be arranged in steps. While blanking by multipunch without step,total blanking force is the sum of each punch force。 therefore, the minimum dimension of the aperture punched can be decreased.(5) Distance between holes in the blanking workpieceThe distances between holes or between the hole and edge should not be too small. Otherwise, the material between the holes may twist. In the case of pound blanking process , the die may break easily due to the material is pulled into die easily。 on the contrary,the distance between them should be langer than .3. Determination of technology scheme in blanking According to the characteristics of the blanking workpiece,the technology scheme of the blanking is determined based on the analysis of the blanking process (1) Combination of the blanking processBlanking process can be divided into single blanking,pound blanking and progressive blanking.The pound blanking is that two or more than two processes are done in the same die position in one press progressive blanking is that several blanking processes are done at different die positions in one press workpicec can be produce in each press stroke but the initial stroke is the productivity of the pound blanking is higher than that of the single blanking,and the tolerance grade of workpiece of the pound blanking is also higher than that of the single blanking.The pound mode of the blanking process is determined by following factors:1) Production batch.Generally,the single blanking is suitable for small batch or trial production,the pound or progressive blanking is suitable for medium and large batch production.2) Dimension tolerance grade of the blanking workpiece.The tolerance grade of the workpiece produced through the pound blanking is high, because multitime locating error can be avoided in this pared with pound blanking, the tolerance grade of the workpiece produced through progressive blanking is low.3) Dimension and shape of the workpiece.When the dimension of the workpiece is small, the pound or progressive blanking is usually adopted in view of inconvenience and low productivity of the single workpiece of medium dimension,the bined blanking is also used because to manufacture several simple dies is more expensive than a bined die. But if the distance between the holes or between hole and edge is too small,it is better to use propressive blanking than pound and single blanking. So the progressive blanking can used to produce abnormal workpieces with plex shape and small width,and the blanking material thickness in progressive blanking is larger than that in pound blanking. The progressive blanking is restricted by the working table dimension of press and the number of proess,so the size of blanking workpiece cannot be too big.
