Mold steel, with its characteristics of "high hardness, high strength, high wear resistance, and corrosion resistance," has become the preferred material for key components such as mold cavities and cores. As the core equipment in mold manufacturing, the milling machine for machining mold steel directly determines the dimensional accuracy and service life of the mold through its machining accuracy, cutting efficiency, and stability.

[0003] The prior art discloses a planar milling machine for machining mold steel, with announcement number CN221088087U. The machine includes: a bed and a worktable mounted on the top; a clamping plate, each with side support seats on its outer side and connected to an electric telescopic rod; an internal gear ring connected to the clamping plate, with driven wheels meshing at corresponding positions on the inner wall teeth of the internal gear ring; a driving wheel installed at the center of the inner cavity of the internal gear ring and meshing with the driven wheels; and a second electric motor installed at the center of the outer side of the side support seats and coaxially connected to the gear shaft of the driving wheel. In this planar milling machine for machining mold steel, after the clamping plate clamps and fixes the mold steel under the drive of the side support seats, the side support seats and connecting structure rise under the action of the telescopic end of the electric telescopic rod, and the second electric motor drives the driving wheel to rotate.
