45、规模效益，使得模具向着高速、精密、长寿命方向发展；另一方面企业为了满足多品种、小批量、产品更新换代快、赢得市场的需要，要求模具向着制造周期短、成本低的快速经济的方向发展。计算机、激光、电子、新材料、新技术的发展，使得快速经济制模技术如虎添翼，应用范围不断扩大，类型不断增多，创造的经济效益和社会效益越来越显著。快速经济制模技术与传统的机械加工相比，具有制模周期短、成本低、精度与寿命又能满足生产上的使用要求，是综合经济效益比较显著的一类制造模具的技术，概括起来，有以下几种类别。1、快速原型制造技术快速原型制造技术简称RPM，是80年代后期发展起来的一种新型制造技术。美国、日本、英国、以色列、德国、
46、中国都推出了自己的商业化产品，并逐渐形成了新型产业。RPM是电脑、激光、光学扫描、先进的新型材料、计算机辅助设计CAD、计算机辅助加工CAM、数控CNC综合应用的高新技术。在成型概念上以平面离散、堆积为指导，在控制上以计算机和数控为基础，以最大柔性为总体目标。它摒弃了传统的机械加工方法，对制造业的变革是一个重大的突破，利用RPM技术可以直接或间接地快速制模，该技术已被汽车、航空、家电、船舶、医疗、模具等行业广泛应用。2、表面成型制模技术表面成型制模技术，主要是利用喷涂、电铸、化学腐蚀等新的工艺电弧喷涂成型制模技术电弧喷涂成型技术的原理是利用2根通电的金属丝之间产生电弧的热量将金属丝熔化，依靠高
47、压气体将其充分雾化，并给予一定的动能，高速喷射在样模表面，层层镶嵌，形成一金属壳体，即型腔的内表面，再用充填基体材料一般为金属粉粒与树脂的复合材料加以支撑加固，提高其强度和刚性，连同金属模架组合成模具。这种制模技术工艺简单、成本低，制造周期非常短，型腔表面的成型仅需几个小时，节省能源和金属材料，一般型腔表面仅23MM厚，仿真性极强，花纹精度可达到05M。目前该技术被广泛地用于飞机、汽车的内饰件模具、家电、家俱、制鞋、美术工艺品等表面形状复杂及花纹精细的各种聚氨酯制品的吹塑、吸塑、PVC注射、PU电铸成型技术电铸成型技术的原理同电镀一样，是依样模现成制品或按制品图纸制成的母模为基准阴极，置放在电
48、铸液中阳极，使电铸液中的金属离子还原后一层一层地沉积在样模上，形成金属壳体，将其剥离后，与样模接触的表面即为模具的型腔内表面。该技术主要特点是节省材料、模具制造周期短，电铸层硬度可达40HRC，提高了耐磨性和寿命，粗糙度、尺寸精度与样模完全一致，适用于注射、吸塑、吹塑、搪塑、胶木模、玻璃模、压铸模等模具型腔及电火花成型电极的制造。它的基本原理是先把花纹图案制成胶片，再把胶片上的花纹图案复制在已涂上光敏材料的模具型腔表面上，经过化学处理，模具型腔表面形成不被蚀刻部分的保护层，再根据模具材质，选择相应蚀刻工艺，将花纹图案蚀刻在模具内表面上。该技术的主要特点是时间短、费用低，修补破损花纹图案可做到天
49、衣无缝。3、型腔表面不需要机械加工。4、挤压成型技术利用铍铜合金的良好的导热性和稳定性，经固熔时效处理后，采用冷挤压制造模具凹模型腔。其特点是制造周期短，型腔精度高IT7级，表面粗糙度RA0025M,强度高，寿命可达50万次，无环境污染。该技术是利用金属材料在细化晶粒、一定成型温度、低变形速率条件下，材料具有最佳超塑性时，将事先制作好的凸模，用较小的力便可挤压出凹模的一种快速经济制模技术。超塑成型材料的典型代表是ZN22AL5、CAD/CAM/CAT技术为主要手段，利用计算机控制高度可调基本体群形成上下成形面，代替传统模具对板料进行三维曲面成形的又一现代先进制造技术。此项技术可以随意改变变形路径与受力状态，提高材料的成形极限，可反复6、凯维朗KEVRON具有凸、凹模结构的钢带模，它是由单刃钢带与特制垫板组成的新型快速经济制模技术。这种模具重量轻，一般只有200KG，加工精度为035050MM，可适合各种黑色和有色金属的05065MM厚的板料加工。寿命可达到5257、模具毛坯的快速制造技术现代模具毛坯已广泛地采用子实型铸造技术，所谓实型铸造就是利用泡沫塑料聚苯乙烯PS或聚甲基丙烯酸酯PMMA制作代替传统的木模或金属模，造型后不需取出模型，便可以浇铸，泡沫塑料模型的高温液体金属作用下，迅速燃烧气化而消失，金属液取代原来泡沫塑料模型所占有的位置，冷凝后形成铸件8、外也先后
