42、會(huì)效益越來(lái)越顯著。  快速經(jīng)濟(jì)制模技術(shù)與傳統(tǒng)的機(jī)械加工相比，具有制模周期短、成本低、精度與壽命又能滿足生產(chǎn)上的使用要求，是綜合經(jīng)濟(jì)效益比較顯著的一類制造模具的技術(shù)，概括起來(lái)，有以下幾種類別。   1快速原型制造技術(shù) 快速原型制造技術(shù)簡(jiǎn)稱RPM，是80年代后期發(fā)展起來(lái)的一種新型制造技術(shù)。美國(guó)、日本、英國(guó)、以色列、德國(guó)、中國(guó)都推出了自己的商業(yè)化產(chǎn)品</p><p

43、>　　電弧噴涂成型制模技術(shù)  電弧噴涂成型技術(shù)的原理是：利用2根通電的金屬絲之間產(chǎn)生電弧的熱量將金屬絲熔化，依靠高壓氣體將其充分霧化，并給予一定的動(dòng)能，高速噴射在樣模表面，層層鑲嵌，形成一金屬殼體，即型腔的內(nèi)表面，再用充填基體材料(一般為金屬粉粒與樹脂的復(fù)合材料)加以支撐加固，提高其強(qiáng)度和剛性，連同金屬模架組合成模具。這種制模技術(shù)工藝簡(jiǎn)單、成本低，制造周期非常短，型腔表面的成型僅需幾個(gè)小時(shí)，節(jié)省能源和金屬材料

44、，一般型腔表面僅2-3mm厚，仿真性極強(qiáng)，花紋精度可達(dá)到0.5μm。 目前該技術(shù)被廣泛地用于飛機(jī)、汽車的內(nèi)飾件模具、家電、家俱、制鞋、美術(shù)工藝品等表面形狀復(fù)雜及花紋精細(xì)的各種聚氨酯制品的吹塑、吸塑、PVC注射、PU發(fā)泡及各類注射成型模具中。     電鑄成型技術(shù) 電鑄成型技術(shù)的原理同電鍍一樣，是依樣模(現(xiàn)成制品或按制品圖紙制成的母模)為基準(zhǔn)(陰極)，置放在電鑄液中(陽(yáng)極

45、)，使電鑄液中的金屬離子還原后一層一層地沉積在樣模上，形成金屬殼體，將其剝離后，與樣模接觸的表面即為模具的型腔內(nèi)表面。該技術(shù)主要特點(diǎn)是節(jié)省材料、模具制造周期短，電鑄層硬度可達(dá)40HRC，提高了耐磨性和壽命，粗糙度</p><p>　　型腔表面精細(xì)花紋成型的蝕刻技術(shù)蝕刻技術(shù)是光學(xué)、化學(xué)、機(jī)加工綜合應(yīng)用的一種技術(shù)，它的基本原理是先把花紋圖案制成膠片，再把膠片上的花紋圖案復(fù)制在已涂上光敏材料的模具型腔表面上，經(jīng)過(guò)化學(xué)

46、處理，模具型腔表面形成不被蝕刻部分的保護(hù)層，再根據(jù)模具材質(zhì)，選擇相應(yīng)蝕刻工藝，將花紋圖案蝕刻在模具內(nèi)表面上。  該技術(shù)的主要特點(diǎn)是時(shí)間短、費(fèi)用低，修補(bǔ)破損花紋圖案可做到天衣無(wú)縫。</p><p>　　3澆鑄成型制模技術(shù)澆鑄成型制模技術(shù)的共同特點(diǎn)是依樣件為基準(zhǔn)，澆鑄出凸、凹模，型腔表面不需要機(jī)械加工。</p><p>　　4擠壓成型技術(shù)   

47、;利用鈹銅合金的良好的導(dǎo)熱性和穩(wěn)定性，經(jīng)固熔時(shí)效處理后，采用冷擠壓制造模具凹模型腔。其特點(diǎn)是制造周期短，型腔精度高(IT7級(jí))，表面粗糙度Ra=0.025μm,強(qiáng)度高，壽命可達(dá)50萬(wàn)次，無(wú)環(huán)境污染。該技術(shù)是利用金屬材料在細(xì)化晶粒、一定成型溫度、低變形速率條件下，材料具有最佳超塑性時(shí)，將事先制作好的凸模，用較小的力便可擠壓出凹模的一種快速經(jīng)濟(jì)制模技術(shù)。超塑成型材料的典型代表是Zn-22%AL。   5無(wú)模多點(diǎn)成

48、形技術(shù)  無(wú)模多點(diǎn)快速成形技術(shù)是以CAD/CAM/CAT技術(shù)為主要手段，利用計(jì)算機(jī)控制高度可調(diào)基本體群形成上下成形面，代替?zhèn)鹘y(tǒng)模具對(duì)板料進(jìn)行三維曲面成形的又一現(xiàn)代先進(jìn)制造技術(shù)。此項(xiàng)技術(shù)可以隨意改變變形路徑與受力狀態(tài)，提高材料的成形極限，可反復(fù)成形，以此消除材料內(nèi)部的殘余應(yīng)力，實(shí)現(xiàn)無(wú)回彈成形。    6凱維朗(KEVRON)鋼帶沖裁落料制模技術(shù)  新型鋼帶沖裁
