摘要： A computing system (100) may include a design access engine (108) configured to access an injection mold design (210) and a channel construction engine (110) configured to construct conformal cooling channels (510) for the injection mold design (210). The channel construction engine (110) may do so by extracting a cooling surface (600) of the injection mold design (210), generating a central offset surface (220) with a same shape as the cooling surface (600), projecting cooling lines (310) on to the central offset surface (220), detecting sharp portions (410) of the projected cooling lines (320), smoothing the detected sharp portions (410) of the projected cooling lines (320), and generating the conformal cooling channels (510) using the smoothed cooling lines (420) along the central offset surface (220) as a center line for the conformal cooling channels (510). It also relates to the method and a non-transitory machine-readable medium (820) comprising instructions (822, 824).
