Abstract

The present disclosure provides an impeller and a mold for manufacting the impeller. The impeller includes a plurality of blades, and there is an overlapped area between two adjacent blades. The mold includes a first part, a second part and a plurality of slide groups. The first part and the second part move in a mold opening direction. At least a portion of each slide group is located in the overlapped area, and each slide group has a first slide block and a second slide block, and a movement direction of the first slide block and the second slide block is perpendicular to the mold opening direction. By using that the movement direction of the slide group is perpendicular to the mold opening direction, the impeller with blades that have the overlapped area may be manufactured.
