摘要
在現(xiàn)代工業(yè)中，模具工業(yè)已經(jīng)成為制造業(yè)的基礎，這一觀點隨著全球制造業(yè)向我國轉移的過程中被越來越多的有識之士所意識到。而在模具行業(yè)中塑料模又是其重中之重，此種模具占模具行業(yè)值的50%以上，我國的塑料成型模具設計，制作技術比較晚，整體水平還比較低。目前單型腔、簡單型腔的模具達70%以上，占主導地位。
本論文介紹了讀卡器蓋注射模具的設計過程。從讀卡器蓋的測繪，分型面的確定，型腔數(shù)目和布局的確定，注射機選擇，澆注系統(tǒng)設計，冷卻系統(tǒng)設計，模板及其標準件的選用，脫模機構的設計，成型部件的設計等一一進行了詳細的介紹。
通過本設計，可以對注射模具有一個初步的認識，模架的結構及其動作原理都有了一定的了解。注射模是安裝在注射機上的，因此在設計注射模時應該對注射機的有關技術規(guī)范進行必要的了解，以便設計出符合要求的模具，同時選定合適的注射機型號。
關鍵詞 注射模；模具設計；讀卡器蓋；模架
Abstract
In modern industry, die industry has become the basis of manufacturing,this view as the process of the global manufacturing transfer to China being awared by more and more insightful people. The plastic mould is top priority in the die industry, such mould of the die industry production value over 50 percent. China's plastic mold design, production technology relatively late, the overall level is still relatively low.At present, single-cavity and simple cavity of the mold more than 70 percent, it’s dominated.
This paper introduces the reader cap injection mold design process. From the card reader cover mapping, sub-surface determination, the determination of cavity number and layout of the injection machine selection, gating system design, cooling system design, selection of templates and standard parts, ejection mechanism design, molding parts the design of one by one in detail.
Through this design,I can have a preliminary understanding of the injection mold ,the die carrier’s frame and action principle.Understanding the selected of die carrier and injection machine need through to calculation the various size and check the Strength.
Keywords Plastic injection mould Mould design Reader cover Die carrier
