[0002] During the production process of an aluminum alloy low-pressure casting die, axial deformation of the bottom die may occur. The center of the bottom die may bulge upward or sink downward. The deformation of the bottom die will cause deformation of the wheel hub casting, affecting the appearance and dimensions of the machining. When the wheel hub casting is deformed, uneven machining will appear on the surface of the wheel hub casting. The bottom die of the die is in a shape with a middle bulge. The traditional depth checking tool cannot detect the axial deformation amount of the bottom die, or a special support is used for detection. However, the special support can only detect wheel types with fixed dimensions, and the manufacturing accuracy of the special support is often low, affecting the detection effect; the depth gauge and the support need to be matched for measurement, the operation is cumbersome, and the detection accuracy is affected; when the traditional depth gauge is detecting, it is necessary to calculate the difference between the detected dimension and the reference plane to calculate the axial deformation amount, and the detection efficiency is low.
