将快速原型制造与转移涂料精密铸造结合 ,对复杂曲面金属模具的快速制作方法进行了探索。该方法用三维造型软件设计模具 ,用分层制作技术快速得到模具原型 ,再基于原型直接采用转移涂料工艺 ,制作出近净型金属模具毛坯。该工艺流程短 ,成本较低 ,特别适合砂型铸造或消失模铸造用的小型金属模具的快速制作 The combination of rapid prototyping and cast transfer precision casting has been explored for the rapid fabrication of complex curved metal molds. The method uses three-dimensional modeling software to design the mold, and uses the layered production technology to quickly obtain the prototype of the mold, and then directly uses the transfer coating process based on the prototype to make the near-net-shape metal mold blank. The process is short, the cost is low, especially for sand casting or lost foam casting mold for the rapid production of small metal mold
