12、復(fù)雜的精密塑件。加工仿真模擬真實(shí)加工過(guò)程，降低生產(chǎn)成本，避免新產(chǎn)品開(kāi)發(fā)的風(fēng)險(xiǎn)。首先選擇鼠標(biāo)的材料，對(duì)鼠標(biāo)進(jìn)行功能和結(jié)構(gòu)工藝分析，參照“巡洋艦”鼠標(biāo)運(yùn)用UG軟件進(jìn)行鼠標(biāo)的三維建模和裝配。借助于UG軟件的注塑模設(shè)計(jì)功能，運(yùn)用注塑模的知識(shí)，通過(guò)設(shè)置注塑模具的各項(xiàng)參數(shù)設(shè)計(jì)了鼠標(biāo)上殼的注塑模。運(yùn)用UG軟件的仿真加工模塊對(duì)模具型腔進(jìn)行了仿真加工。首先進(jìn)行型腔銑：開(kāi)粗；然后進(jìn)行型腔銑：半精加工凹模；之后進(jìn)行曲面銑：精加工凹模。工藝參數(shù)設(shè)置完成后，可生

13、成數(shù)控加工代碼，進(jìn)行仿真加工。設(shè)計(jì)表明，運(yùn)用UG軟件進(jìn)行注塑模設(shè)計(jì)，直觀、便于修改，能明顯降低注塑模設(shè)計(jì)難度、節(jié)約時(shí)間；借助于UG的仿真加工功能，能檢驗(yàn)?zāi)＞咴O(shè)計(jì)的正確性和工藝的可行性。關(guān)鍵詞：關(guān)鍵詞：UG軟件；產(chǎn)品三維造型；注塑模設(shè)計(jì)；仿真加工ThirdgearshiftphotoelectricshellcavityinjectionmolddesignmachiningsimulationmouseAbstractAbstract：
