The invention relates to a magnetic shoe mold and provides a permanent magnetic ferrite magnetic shoe mold which is simple in structure, enables a magnetic force line to be radial from an outer arc toan inner arc during magnetic shoe molding and realizes increasing of the magnetic flux density of an outer arc surface of a magnetic shoe and improvement of the magnetic field intensity. Through thepermanent magnetic ferrite magnetic shoe mold, the technical problems that the surface magnetic field intensity of the inner arc of the magnetic shoe is greater than that of the outer arc in the molding process and the usage requirements cannot be met in the prior art are solved. The permanent magnetic ferrite magnetic shoe mold comprises an upper mold, a concave mold and a lower mold which are fixed to a mold base. The lower mold is inserted in a center hole of the concave mold, and the lower mold and the upper mold jointly define an arc-shaped magnetic shoe mold cavity. The convex surface ofthe arc-shaped magnetic shoe mold cavity faces the upper mold. An upper insert is arranged in the position, corresponding to the upper mold, of the upper surface of the arc-shaped magnetic shoe moldcavity. The top end of the lower mold is provided with a lower insert matched with the concave surface of the arc-shaped magnetic shoe mold cavity. An annular middle mold is clamped between the uppermold and the concave mold outside the arc-shaped magnetic shoe mold cavity correspondingly. The upper insert, the concave mold and the lower mold are all made of a strong magnetic material. The uppermold, the lower insert and the annular middle mold are all made of a weak magnetic material.
