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(lái)的熱量通過(guò)熱輻射傳遞給材料和模具的鋼材，通過(guò)對(duì)流傳遞給導(dǎo)熱流體。另外，熱量通過(guò)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(lái)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。有效控制模具溫度的預(yù)備條件溫度控制系統(tǒng)由模具、模溫機(jī)、導(dǎo)熱流體三部分組成。為了確保熱量能加給模具或移走，系統(tǒng)各部分必須滿足以下條件:首先是在模具內(nèi)部，江蘇注塑模具品牌哪家好，冷卻通道的表面積必須足夠大，流道直徑要匹配泵的能力(泵的壓力)。型腔中的溫度分布對(duì)零件變形和內(nèi)在壓力有很大的影響，江蘇注塑模具品牌哪家好。合理設(shè)置冷卻通道可以降低內(nèi)在壓力，江蘇注塑模具品牌哪家好，從而提高了注塑件的質(zhì)量。它還可以縮短循環(huán)時(shí)間，降低產(chǎn)品成本。
