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(duì)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(duì)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，滄縣塑料模具廠家電話，常加元素Cr，同時(shí)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(jìn)行滲碳和淬火回火處理，表面硬度可達(dá)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，滄縣塑料模具廠家電話，無塌陷及表面剝落現(xiàn)象，模具壽命提高。鋼中元素cr，滄縣塑料模具廠家電話，Ni、Mo、V增加滲碳層的硬度和耐磨性及心部的強(qiáng)韌性。滄縣塑料模具廠家電話</p><div

style="text-indent:25px">塑料模的工作條件由于塑料及塑料成型工業(yè)的發(fā)展，對(duì)塑料的模具的質(zhì)量要求也越來越高，因而塑料模具的失效問題及其影響因素已成為重要的研究課題。塑料模的主要工作零件是成型零件，如凸模、凹模等，它們構(gòu)成塑料模的型腔，以成型塑料制件的各種表面并直接與塑料接觸，經(jīng)受壓力、溫度、摩擦和腐蝕等作用。塑料模材料失效原因分析一般模具制造中包括模具設(shè)計(jì)、選用材料、熱處理、機(jī)械加工、調(diào)試與安裝等過程。根據(jù)調(diào)查表明：模具失效的因素中，模具所使用的材料與熱處理是影響使用壽命的主要因素。從全（quan）面質(zhì)量管理的角度出發(fā)，不能把影響模具使用壽命的諸因素作為多項(xiàng)式之和來衡量，而應(yīng)該是多因素的乘積，這樣，模具材料與熱處理的優(yōu)劣在整個(gè)模具制造過程中就顯得特別重要。 </p><p style="text-indent:25px">高發(fā)泡聚苯乙烯成型模具是應(yīng)用可發(fā)性聚苯乙烯（由聚苯乙烯和發(fā)泡劑組成的珠狀料）原料來成型各種所需形狀的泡沫塑料包裝材料的一種模具。其原理是可發(fā)聚苯乙烯在模具內(nèi)能入蒸汽成型，包括簡易手工操作模具和液壓機(jī)直通式泡沫塑料模具兩種類型，主要用來生產(chǎn)工業(yè)品方面的包裝產(chǎn)品。制造此種模具的材料有鑄鋁、不銹鋼、青銅等。設(shè)計(jì)要素模具設(shè)計(jì)和制造與塑料加工有密切關(guān)系。塑料加工的成敗，很大程度上取決于模具設(shè)計(jì)效果和模具制造質(zhì)量，而塑料模具設(shè)計(jì)又以正確的塑料制品設(shè)計(jì)為基礎(chǔ)。塑料模具設(shè)計(jì)要考慮的結(jié)構(gòu)要素有： ①分型面，即模具閉合時(shí)凹模與凸模相互配合的接觸表面。它的位置和形式的選定，受制品形狀及外觀、壁厚、成型方法、后加工工藝、模具類型與結(jié)構(gòu)、脫模方法及成型機(jī)結(jié)構(gòu)等因素的影響。 ②結(jié)構(gòu)件，即復(fù)雜模具的滑塊、斜頂、直頂塊等。結(jié)構(gòu)件的設(shè)計(jì)非常關(guān)鍵，關(guān)系到模具的壽命、加工周期、成本、產(chǎn)品質(zhì)量等，因此設(shè)計(jì)復(fù)雜模具**結(jié)構(gòu)對(duì)設(shè)計(jì)者的綜合能力要求較高，盡可能追求更簡便、更耐用、更經(jīng)濟(jì)的設(shè)計(jì)方案。

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(dòng)，凝固的塑件從模具中脫出，都對(duì)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(shí)，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(jìn)入塑模型腔時(shí)，它會(huì)加劇型腔面的磨損。加之塑料加工時(shí)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(shí)又有磨損損傷，使型腔表面的鍍層或其他防護(hù)層遭到破壞，則將促進(jìn)腐蝕過程。兩種損傷交叉作用，加速了腐蝕一磨損失效。滄縣塑料模具廠家電話</p><p style="text-indent:25px">滄縣塑料模具廠家電話</p><p style="text-indent:25px">足夠耐磨性隨著塑料制品用途的擴(kuò)大，在塑料中往往需添加玻璃纖維之類的無機(jī)材料以增強(qiáng)塑性，由于添加物的加入，使塑料的流動(dòng)性**降低，導(dǎo)致模具的磨損，故要求其具有良好的耐磨性。 3）優(yōu)良的切削加工性大多數(shù)塑料成型模具，除電火花加工還需進(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，在切削過程中加工硬化小。為避免模具變形而影響精度，希望加工殘余應(yīng)力能控制在**小限度。良好的熱穩(wěn)定性塑料注射模的零件形狀往往比較復(fù)雜，淬火后難以加工，因此應(yīng)盡量選用具有良好的熱穩(wěn)定性的材料。滄縣塑料模具廠家電話</p><p
