摘　　要：研究将SLS粉末快速成形方法应用于注塑模具随形冷却水路的快速制造,此方法形成的内置水路是随形的,其不但可以保证注塑模具型腔表面的均匀传热,而且在保证机械性能的前提下,能够克服扭曲变形和熔接痕等不良缺陷,注塑成型的塑件外观满足高光无痕的要求,能大幅缩短注塑周期和提高生产率。It studies the SLS powder rapid prototyping method is applied to injection mold-shaped cooling channels,the formation of built-in water channels by this method,it is not only can guarantee the uniformity of injection mold cavity surface transfers heat evenly,but also in ensuring under the premise of the mechanical performance,it can pruduces working parts of the injection mold which achieves rapid injection molding and high-light and traceless of the plastic parts directly,overcomes the distortion and weld traces and other undesirable defects,significantly shortens the molding cycle and increases productivity.
