style="text-indent:25px">在設(shè)計(jì)模具時(shí)需要考慮哪些因素呢？ 1.要考慮注塑成本，根據(jù)機(jī)臺(tái)大小每啤多少錢(qián)，從而確定產(chǎn)品排位方式和穴數(shù)。 2.考慮產(chǎn)品外觀，確定分型面。分型面的位置要有利于模具加工、排氣、脫模等。 3.考慮水口方式，確定主流道和分流道的形狀、大小、以及排氣方位。 4.考慮產(chǎn)品脫模，確定頂出方式和布置頂針位置。 5.考慮產(chǎn)品縮水和注塑時(shí)間，確定冷卻或加熱形式并排好冷卻道的部位。 6.考慮模具壽命，確定模具材料硬度、厚度和大小尺寸。 7.考慮加工難度，確定成型零件分拆和做好線割結(jié)構(gòu)形狀。</p><p style="text-indent:25px">模具加工精度把握之因素： (1)上模芯1與上模芯2的壓合：上模芯1與上模芯2的壓合是保證油封副唇尺寸及精度的關(guān)鍵。三開(kāi)油封模具副唇處的飛邊,對(duì)副唇處的外觀影響比較大。新結(jié)構(gòu)模具將上模芯1與上模芯2采用過(guò)盈配合，單體加工后，用熱脹法壓合成一體，再由上端的緊固螺釘將上模芯2緊緊拉住，有效地阻止副唇處兩模芯的松動(dòng)。 (2)各腔模具之間的連接：各單腔模具與聯(lián)板的連接必須有一定的浮動(dòng)量，以保證精密模具加工開(kāi)合靈活，找正準(zhǔn)確。一般單模與聯(lián)板間的間隙控制在0。50一1。0rnm。間隙過(guò)大易造成模具使用時(shí)偏旋轉(zhuǎn)軸油封新結(jié)構(gòu)模具的研制斜太大，模具磨損加劇，影響模具的使用壽命；間隙過(guò)小則使模具操作時(shí)各模腔間發(fā)生干涉，卡得過(guò)。旋轉(zhuǎn)軸油封兩開(kāi)模具的研制改變了傳統(tǒng)三開(kāi)模結(jié)構(gòu)型式，使油封制品外觀及性能得以保證，較大提高了工作效率。所謂數(shù)字化模具技術(shù)，就是計(jì)算機(jī)技術(shù)或計(jì)算機(jī)輔助技術(shù)(CAX)在模具設(shè)計(jì)制造過(guò)程中的應(yīng)用。</p><div
