Abstract: A central heat-insulation hole structure for an aluminum wheel low-pressure water-cooling casting mold. The structure includes a top mold and a central heat-insulation hole. A split unit structure including a top mold and central flange loose pieces is changed into a non-split integrated top mold. Besides, a circle of uniformly distributed heat-insulation holes are thrilled in a circumferential direction of the position of a mold split unit parting surface of the original top mold and the central flange loose pieces. The diameter of each heat-insulation hole is 8 mm, the size of a wheel flange defines the number of the heat-insulation holes and the diameter of circumference of the heat-insulation holes distributed in the integrated top mold, and in order to ensure the service life and water cooling and heat insulation effects of the mold, the depth of each heat-insulation hole from the surface of a cavity is more than 20 mm.
