This utility model discloses a die-casting mold that facilitates subsequent burr removal, comprising an upper mold and a lower mold that move in a vertical direction. The lower mold has a forming cavity with its opening facing upwards. The mold also has multiple forming ribs arranged spaced apart from each other in the left-right direction within the forming cavity. The upper mold has forming grooves of the same number as the forming ribs, which fit together one-to-one. The upper ends of the forming ribs are placed in the forming grooves after the upper and lower molds are closed. The surface of the upper end of the forming rib includes a top surface and two upwardly inclined, narrowing left and right slopes. The top surface connects the left and right slopes, and at least a portion of the top surface is parallel to the parting surface of the die-casting mold. The wall of the forming groove includes a groove bottom surface facing the top surface, a left groove side slope facing the left slope, and a right groove side slope facing the right slope. At least a portion of the groove bottom surface is parallel to the parting surface. This facilitates subsequent burr removal operations on the die-cast product.
