style="text-indent:25px">注塑模具的熱平衡控制注塑機(jī)和模具的熱傳導(dǎo)是生產(chǎn)注塑件的關(guān)鍵。模具內(nèi)部，由塑料(如熱塑性塑料)帶來的熱量通過熱輻射傳遞給材料和模具的鋼材，通過對流傳遞給導(dǎo)熱流體。另外，熱量通過熱輻射被傳遞到大氣和模架。被導(dǎo)熱流體吸收的熱量由模溫機(jī)來帶走。模具的熱平衡可以被描述為:P=Pm-Ps。式中P為模溫機(jī)帶走的熱量;Pm為塑料引入的熱量;Ps為模具散發(fā)到大氣的熱量。控制模具溫度的目的和模具溫度對注塑件的影響注塑工藝中，控制模具溫度的主要目的一是將模具加熱到工作溫度，二是保持模具溫度恒定在工作溫度。以上兩點(diǎn)做的成功的話，可以把循環(huán)時(shí)間優(yōu)化，進(jìn)而保證注塑件穩(wěn)定的高質(zhì)量。模具溫度會影響表面質(zhì)量，流動性，收縮率，注塑周期以及變形等幾方面。模具溫度過高或不足對不同的材料會帶來不同的影響。對熱塑性塑料而言，模具溫度高一點(diǎn)通常會改善表面質(zhì)量和流動性，但會延長冷卻時(shí)間和注塑周期。模具溫度低一點(diǎn)會降低在模具內(nèi)的收縮，但會增加脫模后注塑件的收縮率。而對熱固性塑料來說，高一點(diǎn)的模具溫度通常會減少循環(huán)時(shí)間，且時(shí)間由零件冷卻所需時(shí)間決定。此外，在塑膠的加工中，高一點(diǎn)的模具溫度還會減少塑化時(shí)間，減少循環(huán)次數(shù)。</p><p
