style="text-indent:25px">塑料壓塑模具：包括壓縮成型和壓注成型兩種結(jié)構(gòu)模具類型。它們是主要用來成型熱固性塑料的一類模具，其所對應(yīng)的設(shè)備是壓力成型機(jī)。壓縮成型方法根據(jù)塑料特性，將模具加熱至成型溫度(一般在103°-108°)，然后將計(jì)量好的壓塑粉放入模具型腔和加料室，閉合模具，塑料在高熱，高壓作用下呈軟化粘流，經(jīng)一定時(shí)間后固化定型，成為所需制品形狀。壓注成型與壓縮成型不同的是有單獨(dú)的加料室，成型前模具先閉合，塑料在加料室內(nèi)完成預(yù)熱呈粘流態(tài)，在壓力作用下調(diào)整擠入模具型腔，硬化成型。壓縮模具也用來成型某些特殊的熱塑性塑料如難以熔融的熱塑性塑料(如聚加氟乙烯)毛坯(冷壓成型)，光學(xué)性能很高的樹脂鏡片，輕微發(fā)泡的硝酸纖維素汽車方向盤等。壓塑模具主要由型腔、加料腔、導(dǎo)向機(jī)構(gòu)、推出部件、加熱系統(tǒng)等組成。壓注模具普遍用于封裝電器元件方面。壓塑模具制造所用材質(zhì)與注射模具基本相同。廣東底座模具制造哪家好我國模具工業(yè)的技術(shù)水平近年來也取得了長足的進(jìn)步。</p><div

style="text-indent:25px">近年來，中國模具制造程度已有較大進(jìn)步。中國塑料模具增長迅速，比重不斷提高。近年來，中國塑料模具發(fā)展迅速。塑料模具在整個(gè)模具行業(yè)中所占比重約為30%，在模具進(jìn)出口中的比重高達(dá)50~70%。隨著中國機(jī)械的發(fā)展，汽車、家電、電子信息在塑料橡膠模具在模具進(jìn)出口中所占的比重逐年增加。據(jù)了解，制造一款普通轎車約需200多件內(nèi)飾件模具，而制造保險(xiǎn)杠、儀表盤、油箱、方向盤等所需的大中型塑料模具*約50%能夠滿足。而塑料建材大量替代傳統(tǒng)材料也成為所趨，預(yù)計(jì)2010年全國塑料門窗和塑管普及率將達(dá)到30%~50%，塑料排水管市場占有率將超過50%，這些都會(huì)增加對模具的需求。據(jù)**預(yù)測，模具市場的總體趨勢是平穩(wěn)向上的，在未來的模具市場中，塑料模具的發(fā)展速度將高于其它模具，在模具行業(yè)中的比例將逐步提高。</p><p style="text-indent:25px">3D打印技術(shù)在模具行業(yè)中的應(yīng)用：1、直接制作手板：3D打印工藝都能制作手板，只是制作出來的手板的精度、強(qiáng)度和表面質(zhì)量有區(qū)別，這也是目**D打印技術(shù)常見的應(yīng)用方式；2、間接制造模具：即利用3D打印的原型件，通過不同的工藝方法翻制模具，如硅橡膠模具、石膏模具、環(huán)氧樹脂模具、砂型模具等；3、直接制造模具：即利用SLS、DMLS、SLM等3D打印工藝直接制造軟質(zhì)模具或硬質(zhì)模具。傳統(tǒng)的模具制造過程是，在接單后還需對接單項(xiàng)目進(jìn)行評審，評審過關(guān)后制定生產(chǎn)進(jìn)度表，然后進(jìn)行3D軟件修正、模流分析、分型線及進(jìn)料點(diǎn)確定，后反饋給客戶定稿，客戶滿意后才能確定制造用的零件圖，才可以準(zhǔn)備加工流程。其加工流程如圖1所示。從圖1可見，采用傳統(tǒng)的模具制造過程加工出一個(gè)合格的模具所需要的人力、物力較多，生產(chǎn)周期較長。塑膠模具是一種用于壓塑、擠塑、注射、吹塑和低發(fā)泡成型的組合式模具的簡稱。</p><div

style="text-indent:25px">模具面臨的問題：1.公差標(biāo)注不統(tǒng)一不同比例的塑料模具會(huì)制成不同的制品，公差標(biāo)注高意味著塑料模具加工工藝相對復(fù)雜，公差標(biāo)注低意味著塑料模具的精度不夠高。所以，設(shè)計(jì)者設(shè)計(jì)塑料模具考慮模具的公差問題應(yīng)該成為重點(diǎn)?，F(xiàn)有的狀況是，設(shè)計(jì)模具時(shí)仍然有設(shè)計(jì)人員根據(jù)過往的經(jīng)驗(yàn)來設(shè)置公差標(biāo)準(zhǔn)，導(dǎo)致的情況是模具尺寸出現(xiàn)偏差，而且形狀出現(xiàn)改變，這在很大程度上影響到了塑料模具設(shè)計(jì)的質(zhì)量和其參考價(jià)值。2、熱膨脹系數(shù)不統(tǒng)一不同的塑料材料的熱膨脹系數(shù)各不相同，塑料冷卻之后的形狀和大小直接受到熱膨脹系數(shù)的影響。所以，設(shè)計(jì)者在設(shè)計(jì)塑料模具時(shí)，必須考慮熱膨脹系數(shù)，并按照實(shí)際情況的變化，對塑料模具的設(shè)計(jì)尺寸做出及時(shí)的調(diào)整?，F(xiàn)在有一些設(shè)計(jì)者不按照設(shè)計(jì)程序進(jìn)行設(shè)計(jì)，不使用熱膨脹系數(shù)，從而導(dǎo)致的結(jié)果是產(chǎn)品無法滿足實(shí)際的要求，進(jìn)而整個(gè)的塑料模具的設(shè)計(jì)效率降低。模具工業(yè)與各行業(yè)都密切相關(guān)。寧波汽車內(nèi)外飾模具制造加工</p><p
