A pressing-shaping method for manufacturing a circular cooling base for being embedded with fins and a mold used in the method are disclosed. The method includes providing a blank ingot that has a first surface, a second surface, and a lateral circular surface encircling the rims of the first and second surfaces. The method further includes using a mold to press the blank ingot to cause the first surface of the blank ingot to indent inward to form a groove, and to cause a plurality of clipping grooves to be formed on the lateral circular surface of the blank ingot through extrusion. As a result, the blank ingot is shaped into the circular cooling base for being embedded with fins.
