1、摘要近年來(lái),我國(guó)家電工業(yè)的高速發(fā)展對(duì)模具工業(yè),尤其是塑料模具提出了越來(lái)越高的要求,2004年,塑料模具在整個(gè)模具行業(yè)中所占比例已上升到30%左右,據(jù)有關(guān)專(zhuān)家預(yù)測(cè),在未來(lái)幾年中,中國(guó)塑料模具工業(yè)還將持續(xù)保持年均增長(zhǎng)速度達(dá)到10%以上的較高速度的發(fā)展。國(guó)內(nèi)塑料模具市場(chǎng)以注塑模具需求量最大,其中發(fā)展重點(diǎn)為工程塑料模具。注射成型是塑料成型的一種重要方法,它主要適用于熱塑性塑料的成型,可以一次成型形狀復(fù)雜的精密塑件。本課題就是花朵蓋塑料成型工藝與模具設(shè)計(jì),將注塑模具的相關(guān)知識(shí)作為依據(jù),闡述塑料注塑模具的設(shè)計(jì)過(guò)程。(1)通過(guò)運(yùn)用塑料模
2、具設(shè)計(jì)指導(dǎo),機(jī)械制圖,互換性與技術(shù)測(cè)量673A械原理及零件,模具材料及熱處理,模具制造工藝,塑料成型工藝及模具設(shè)計(jì)等方面必要的基礎(chǔ)知識(shí)和專(zhuān)業(yè)知識(shí),分析和解決塑料模具設(shè)計(jì)問(wèn)題,進(jìn)一步鞏固加深和開(kāi)拓所學(xué)的知識(shí)。(2)本設(shè)計(jì)對(duì)花朵蓋塞進(jìn)行的注塑模設(shè)計(jì),利用UG軟件對(duì)塑件進(jìn)行了實(shí)體造型,對(duì)塑件結(jié)構(gòu)進(jìn)行了工藝分析。明確了設(shè)計(jì)思路,確定了注射成型工藝過(guò)程并對(duì)各個(gè)具體部分進(jìn)行了詳細(xì)的計(jì)算和校核。如此設(shè)計(jì)出的結(jié)構(gòu)可確保模具工作運(yùn)用可靠,保證了與其他部件的配合。最后用AutoCAD繪制了一套模具裝配圖和零件圖(3)通過(guò)計(jì)算、繪圖和運(yùn)用技術(shù)標(biāo)
3、準(zhǔn)、規(guī)范、設(shè)計(jì)手冊(cè)等有關(guān)設(shè)計(jì)手冊(cè),進(jìn)行塑料設(shè)計(jì)全面的基本技能訓(xùn)練,為畢業(yè)設(shè)計(jì)打下一個(gè)良好的實(shí)踐基礎(chǔ)。(4)本課題通過(guò)對(duì)榨汁機(jī)料桶杯的注射模具設(shè)計(jì),鞏固和深化了所學(xué)知識(shí),取得了比較滿(mǎn)意的效果,達(dá)到了預(yù)期的設(shè)計(jì)意圖關(guān)鍵詞:塑料模具;注射成型;模具設(shè)計(jì)全套圖紙,加AbstractInrecentyears,therapiddevelopmentofChina'shomeapplianceindustrymoldindustry,especiallyplasticmoldmadeincreasingdemands,in2004,t
