style="text-indent:25px">塑料模具的工作條件與冷沖模不同，一般須在150℃-200℃下進(jìn)行工作，除了受到一定壓力作用外，還要承受溫度影響。同一種模具會(huì)有多種失效形式，即使在同一個(gè)模具上也可能出現(xiàn)多種損傷。從塑料模的失效形式可知，合理的選用塑料模具材料和熱處理是十分重要的，因?yàn)樗鼈冎苯雨P(guān)系到模具的使用壽命。所以，塑料模具用鋼應(yīng)滿足以下要求： 1）耐熱性能隨著高速成型機(jī)械的出現(xiàn)，塑料制品運(yùn)行速度加快。由于成型溫度在200--350℃之間，如果塑料流動(dòng)性不好，成形速度又快，會(huì)使模具部分成型表面溫度在極短時(shí)間內(nèi)超過400℃。為保證模具在使用時(shí)的精度及變形微小，模具鋼應(yīng)有較高的耐熱性能。云南塑料模具外殼定做</p><div

1、足夠的表面硬度和耐磨性塑料模的硬度通常在50-60HRC以下，經(jīng)過熱處理的模具應(yīng)有足夠的表面硬度，以保證模具有足夠的剛度。模具在工作中由于塑料的填充和流動(dòng)要承受較大的壓應(yīng)力和摩擦力，要求模具保持形狀的精度和尺寸精度的穩(wěn)定性，保證模具有足夠的使用壽命。模具的耐磨性取決于鋼材的化學(xué)成分和熱處理硬度，因此提高模具的硬度有利于提高其耐磨性。 2、優(yōu)良的切削加工性大多數(shù)塑料成型模具，除EMD加工外還需進(jìn)行一定的切削加工和鉗工修配。為延長切削刀具的使用壽命，提高切削性能，減少表面粗糙度，塑料模具用鋼的硬度必須適當(dāng)。云南塑料模具外殼直銷</p><p
