1、支架塑料注射模具設(shè)計(jì)摘要此論文在第一章緒論中主要介紹了塑料模具現(xiàn)階段的發(fā)展?fàn)顩r,在現(xiàn)代模具設(shè)計(jì)中采用了大量的新技術(shù),新工藝和新材料。模具設(shè)計(jì)已經(jīng)成為一種綜合型技術(shù)。還簡單的介紹了塑料的一般成份及塑料的一些特性。還介紹了注射模具的主要組成部件(如定模板、動(dòng)模板、復(fù)位桿、頂桿、導(dǎo)柱等)及模板的材料選擇。第二章第一節(jié)中寫的是塑料的注塑成型工藝,包括塑料的注塑成型工藝、注塑成型參數(shù)的選擇(溫度、壓力和時(shí)間)。第二節(jié)介紹的是塑料制品的設(shè)計(jì)及設(shè)計(jì)中應(yīng)考慮的因素。塑料制品設(shè)計(jì)的主要內(nèi)容包括塑料制品的幾何形狀、尺寸精度和表面質(zhì)量。在第三章塑料模具的設(shè)計(jì)中介紹了塑料模具設(shè)計(jì)的基礎(chǔ)知識包括:注
2、射模具與注射機(jī)的關(guān)系(基本技術(shù)參數(shù)和選用注射成型機(jī)時(shí)基本工藝參數(shù)的校核)、澆注系統(tǒng)的設(shè)計(jì)(主流道,分流道、澆口的類型等)、成型零件的結(jié)構(gòu)設(shè)計(jì)(模具分型面的選擇和凹模、凸模、型芯的設(shè)計(jì)及組合形式)。及零件的注射模具的設(shè)計(jì)過程。每個(gè)零件的設(shè)計(jì)步驟一般由產(chǎn)品分析及零件選擇、塑件幾何特性分析、注射成型機(jī)的選擇、注射成型機(jī)參數(shù)的校核、澆注系統(tǒng)的設(shè)計(jì)、成型零件的機(jī)構(gòu)設(shè)計(jì)、成型零件的尺寸計(jì)及模具的零件等組成。關(guān)鍵詞 塑料;現(xiàn)代模具;塑料模具;注射機(jī);凸模;冷卻裝置ApparatusShellInjectPlasticMouldDesignandCADSimulateAbstractThi
