style="text-indent:25px">新型塑料模具鋼一般塑料模具常采用正火態(tài)的45鋼或40Cr鋼經(jīng)調(diào)質(zhì)制造。硬度要求較高的塑料模具采用CrWMn或Crl2MoV等鋼制造。對工作溫度較高的塑料模具，可以選擇用韌性高的熱作模具鋼。為了滿足塑料型腔對尺寸精度和表面質(zhì)量的更高要求，新近又研制一系列新型模具鋼。 1）滲碳型塑料模具鋼滲碳型塑料模具鋼主要用于冷擠壓成型型腔復(fù)雜的塑料模具，這類鋼的含碳量較塑料模具低，常加元素Cr，同時加入適量Ni、Mo和v，作用是提高淬透性和滲碳能力，為了便于冷擠壓成形，這類鋼在退火狀態(tài)須有高的塑性和低的變形抗力，退火硬度≤1 00HBS。在冷擠壓成形后進行滲碳和淬火回火處理，表面硬度可達58---62HRC。此類鋼國外有**鋼種，如瑞典的8416、美國的P2和P4等。國內(nèi)常采用12CrNi3A和12Cr2Ni4A鋼、20Cr2Ni4A，耐磨性好，無塌陷及表面剝落現(xiàn)象，模具壽命提高。鋼中元素cr，Ni、Mo、V增加滲碳層的硬度和耐磨性及心部的強韌性。江西塑料模具外殼國家標(biāo)準(zhǔn)</p><div

style="text-indent:25px">型腔表面的磨損和腐蝕塑料熔體以一定的壓力在模腔內(nèi)流動，凝固的塑件從模具中脫出，都對模具成型表面造成摩擦，引起磨損。造成塑料模具磨損失效的根本原因就是模具與物料間的摩擦。但磨損的具體形式和磨損過程則與許多因素有關(guān)，如模具在工作過程中的壓力、溫度、物料變形速度和潤滑狀況等。當(dāng)塑料模具使用的材料與熱處理不合理時，塑料模具的型腔表面硬度低，耐磨性差，其表現(xiàn)為：型腔面因磨損及變形引起的尺寸超差；粗糙度值因拉毛而變高，表面質(zhì)量惡化。尤其是當(dāng)使用固態(tài)物料進入塑模型腔時，它會加劇型腔面的磨損。加之塑料加工時含有氯、氟等成分受熱分解出腐蝕性氣體HC1、HF，使塑料模具型腔面產(chǎn)生腐蝕磨損，導(dǎo)致失效。如果在磨損的同時又有磨損損傷，使型腔表面的鍍層或其他防護層遭到破壞，則將促進腐蝕過程。兩種損傷交叉作用，加速了腐蝕一磨損失效。江西塑料模具外殼價格</p><p
