style="text-indent:25px">周轉(zhuǎn)箱模具溫度對(duì)塑件的質(zhì)量及生產(chǎn)率都有影響。如果模溫太低，塑料板和型腔一接觸就會(huì)產(chǎn)生冷斑或應(yīng)力以致產(chǎn)生裂紋；而模溫太高時(shí)，塑料片材可能粘附在型腔上，塑料脫模時(shí)會(huì)變形，而且延長(zhǎng)了生產(chǎn)周期。因此模溫應(yīng)控制在一定范圍內(nèi)，一般在50℃左右。周轉(zhuǎn)箱模具溫度的控制一般有依靠塑料與周轉(zhuǎn)箱模具接觸之后的自然冷卻、增設(shè)風(fēng)冷裝置加速冷卻和水冷等方法，在模內(nèi)開(kāi)冷卻水道是控制周轉(zhuǎn)箱模具溫度的有效、常用的方法，冷卻水道應(yīng)距型表面8mm以上，以避免產(chǎn)生冷斑。寧波塑料周轉(zhuǎn)箱周轉(zhuǎn)筐模具生產(chǎn)企業(yè)</p></p><br
