摘　　要：对客户提供的玻璃器皿样品尺寸进行三坐标测量,利用RP技术可制得样品的树脂原型,利用石膏模和树脂原型制备模具毛坯的型芯,采用中空的毛坯木模来造型,可快速得到玻璃模具的毛坯;利用RP技术可制得模具电火花加工电极的树脂原型,利用ZrO2熔模铸造技术及有限元模拟技术,对型壳的焙烧过程进行模拟,优化型壳焙烧工艺方案,为电极的制备提供了依据。采用以上工艺,可实现玻璃模具的快速制造。The glass service offered by client was measured in three coordinates dimensions, the RP technology was used to obtain co｜ophony prototype of the specimen. The model core of mould＇ s roughcast was made using gesso mould and colophony prototype, using roughcast＇ s wooden model with a middle hole to molding, can rapidly achieve glass mould＇ s roughcast. The mould＇ s elec- tric spark machining electrode＇ s colophony prototype was made using RP technology. Using ZrO2 molten mould foundry technolo- gy and finite element simulation technology,in order to simulate the model shell＇ s baking process, using this method can optimize technical scheme of model shell＇ s baking process and provide gist for electrode＇ s preparation. Using upper technology can a- chieve rapid making of glass mould.
