style="text-indent:25px">汽車模具所謂的”精”，是因?yàn)槠囀袌龈偁幵絹碓郊ち?，消費(fèi)者越來越成熟、理性和挑剔，尤其是對車身外觀的要求越來越高，而車身質(zhì)量主要由模具和裝焊夾具來保證，這就決定了模具加工設(shè)備必須具備精度高、功能多等特點(diǎn)，如五軸聯(lián)動(dòng)數(shù)控銑床及高速精密數(shù)控銑床主要從歐美進(jìn)口，在國內(nèi)采購不到。滿足以上特點(diǎn)，一是投資大.如一臺大型試模機(jī)械壓力機(jī)需要600～800萬元人民幣，進(jìn)口一臺大型數(shù)控銑床需要80～150萬美元，是國產(chǎn)設(shè)備一5倍：二是固定資產(chǎn)多.設(shè)備折舊費(fèi)用提取多，增加了模具開發(fā)成本，國內(nèi)一般中小型模具廠難以承受。張家港國內(nèi)**汽車模具廠模具是技術(shù)型產(chǎn)品和典型的非定型產(chǎn)品。尤其是汽車覆蓋件模具的技術(shù)含量非常高。</p><div

style="text-indent:25px">同時(shí)由于其硬度相對空冷鋼低，加工時(shí)對刀具的磨損較小，具有良好的切削加工性能，加工成本低。在模具工作時(shí)，由于鉬鉻鑄鐵的散熱性能優(yōu)于其他幾種模具材料，尤其模具在機(jī)械壓力機(jī)上工作時(shí)，其具有良好的抗粘附性(抗咬合性)能比較大化的保護(hù)模具，延長模具使用壽命。維修時(shí)，可以直接對其表面進(jìn)行冷焊，大量節(jié)約維修時(shí)間。但由于其淬火后的硬度相對較低，耐磨性差，生產(chǎn)高強(qiáng)板的模具不會采用鉬鉻鑄鐵。Cr12MoV：屬于高碳高鉻鋼，其含有大量的碳化物和高合金度的馬氏體。</p><p style="text-indent:25px">日用品模具澆口的形式很多，但無論采用什么形式的模具澆口，其開設(shè)的位置對塑件的成形性能及成型質(zhì)量影響都很大。所以，合理選擇模具澆口的開設(shè)位置是提高塑件質(zhì)量的一個(gè)重要設(shè)計(jì)環(huán)節(jié)。在選擇模具澆口位置時(shí)，應(yīng)針對塑料制造的幾何形狀特點(diǎn)及技術(shù)要求，來分析熔融塑料在模內(nèi)的流動(dòng)狀態(tài)，填充條件及排氣條件等因素。模具澆口應(yīng)開設(shè)在塑件斷面比較厚處。當(dāng)塑件的壁厚相差較大時(shí)，若將模具澆口開設(shè)在壁薄處，這是塑料熔體進(jìn)入型腔后，不但流動(dòng)阻力大，而且還易冷卻，影響熔體的流動(dòng)距離，難易保證充填滿整個(gè)型腔。塑件的壁厚處往往是熔體比較晚固化的地方，如果澆口開設(shè)在壁薄處，那么壁厚的地方因塑料熔體收縮得不到補(bǔ)縮而會形成表面凹陷或縮孔。提前給汽車廠提供樣件，是模具開發(fā)后期和車型試制、試驗(yàn)及車身裝焊線調(diào)試之問的并行工程。</p><div
