【正文】 beautiful of the surface and the quality of the products .This mold uses a mold cavity,one minute leaves ,make the congels the material out of the mold ,then,push the products out of the mold . The core and the cavity uses the cooling water system, tuck to exhaust the gas, but avoids the flaw. After ascertaining the project of the structure of the mould, protract mouldfitting drawing. At last, carry out an allaround checkout and auditing and launch into manufacture.Key words: the injection moulds, core , a mold cavity.目 錄摘要 .............................................................................................................................................IABSTRACT...............................................................................................................................II第一章 引言...............................................................................................................................1 課題的背景 和意義 ...........................................................................................................2 注塑模具的現(xiàn)狀和發(fā)展 ...................................................................................................3 本課題的研究對(duì)象、目標(biāo)和方法 ...................................................................................3第二章 設(shè)計(jì)及計(jì)算過程...........................................................................................................5 確定零件加工的整體方案 ...............................................................................................5 注塑工藝參數(shù)的校核 .......................................................................................................7第三章 澆注系統(tǒng)與排氣系統(tǒng)設(shè)計(jì)...........................................................................................9 澆注系統(tǒng)的設(shè)計(jì)原則 ......................................................................................................9 主澆道設(shè)計(jì) .....................................................................................................................10 澆口的設(shè)計(jì) .....................................................................................................................11 冷料穴和拉料桿的設(shè)計(jì) .................................................................................................12 排氣系統(tǒng)的設(shè)計(jì) .............................................................................................................13第四章 成型零件設(shè)計(jì).............................................................................................................14 分型面的選擇 ................................................................................................................14 成型零件的結(jié)構(gòu)與設(shè)計(jì) .................................................................................................14 成型零件尺寸的計(jì)算 .....................................................................................................15第五章 導(dǎo)向與脫模機(jī)構(gòu)設(shè)計(jì).................................................................................................18 導(dǎo)向機(jī)構(gòu)設(shè)計(jì) ................................................................................................................18 脫模機(jī)構(gòu)設(shè)計(jì) .................................................................................................................18第六章 溫度調(diào)節(jié)系統(tǒng)設(shè)計(jì)設(shè)計(jì).............................................................................................20 冷卻系統(tǒng)設(shè)計(jì) ................................................................................................................20總結(jié)...........................................................................................................................................22參考文獻(xiàn)...................................................................................................................................23致謝...........................................................................................................................................24第一章 引言模具是工業(yè)產(chǎn)品生產(chǎn)用的重要工藝裝備。最后繪制模具非標(biāo)準(zhǔn)零件圖，經(jīng)全面審核后投產(chǎn)制造。型芯和型腔采用冷卻水槽結(jié)構(gòu)的冷卻系統(tǒng)，采用各零件間隙排氣，可有限避免缺陷。此模具采用一模二腔,一次分型，通過彈簧、階梯定距桿、橡膠脹套等機(jī)構(gòu)順序開模。根據(jù)其技術(shù)要求和使用要求，選擇塑料種類為 POM，再根據(jù)
