摘　　要：铸型制造是铸造生产的重要组成部分,铸型质量的好坏直接影响到铸件的质量。传统的铸型制造依赖模样或芯盒,成本高,周期长,难以满足单件小批量零件的快速制造和试制。文章介绍了金属件无模铸型数控加工制造技术的工艺原理,加工设备的性能以及该技术在新产品开发中的应用。无模铸型数控加工制造技术无需模样,能快速、准确地将铸型生产出来,改变了传统的铸型制造工艺,具有数字化、精密化、柔性化、绿色化等特点,为单件小批量铸件的快速制造提供解决方案。Casting mold manufacturing is an important component of foundry and the quality of casting molds directly impact the quality of cast.Due to the high cost,long producing cycle and the dependence on mold or core box,traditional casting mold producing is hard to meet the demands of trial-manufacture and rapid manufacture which just need single piece or small volume.Process Principles,function of Processing equipment,and Application in Product Development has been introduced in this paper.Patternless casting CNC manufacturing is a technical renovation compared to the traditional casting manufacturing,with traits of green,digital,flexibility,precision,rapidity.It＇s applicable to the rapid manufacturing of metal casting either in single piece or small lot,and the pattern is unneeded.
