【正文】 egory, while the injection mold is one of the types of rapid development, therefore, research on the understanding of plastic injection molding production process and improve product quality is very significant. The name of the skeleton design products, choose materials for the PP, because the demand for the product, we choose a twocavity mold arrangement, according to mold structure, we applied the lateral type Pulling Mechanism design and the design of the lifter body . Through this design, injection mold can have a preliminary understanding of the design of some of the details of the note issue, to understand the structure and working principle of mold。通過本設(shè)計(jì)，可以對注塑模具有一個(gè)初步的認(rèn)識，注意到設(shè)計(jì)中的某些細(xì)節(jié)問題，了解模具結(jié)構(gòu)及工作原理；通過對 CAD 的學(xué)習(xí)，可以建立較簡單零件的零件庫，從而有效的提高工作效率。目 錄風(fēng)扇按鈕塑料模具設(shè)計(jì)中 文 摘 要……………………………………………………………………………3Abstract …………………………………………………………………………………………3緒論.………………………………………………………………………………………………4第一章 塑件的工藝分析........................................................7 塑件 .................................................................................................................................... 7 工藝分析 ...............................................................................................................................8第二章 擬定模具結(jié)構(gòu)形式......................................................8 分型面的確定 .............................................................8 確定行腔數(shù)和排列方式 .....................................................8第三章 澆注系統(tǒng)的設(shè)計(jì) ..............................................................................................................10 主流道的設(shè)計(jì) .....................................................................................................................10 分流道的設(shè)計(jì) ....................................................................................................................11 澆口的設(shè)計(jì).........................................................................................................................11 分流道的分布 ..........................................................12第四章 成型零件的設(shè)計(jì).......................................................12 成型零件的結(jié)構(gòu)設(shè)計(jì) ........................................................................................................12 成型零件鋼材選用......................................................13 動模的大小............................................................13 主要成型零件的工作尺寸計(jì)算............................................13 定模的設(shè)計(jì)............................................................14第五章 推出機(jī)構(gòu)的設(shè)計(jì).......................................................14 推出機(jī)構(gòu)設(shè)計(jì)原則 ............................................................................................................14 脫模力................................................................14 推桿的機(jī)構(gòu)設(shè)計(jì) ........................................................14 推出形式的確定........................................................14第六章 模架的確定...........................................................15 A 板（定模固定板） .........................................................................................................15 B 板（動模固定板）
