The alloy material enters the cavities of the first groove 34 and the second groove 44 to shape the mounting ring 23; the alloy material can not enter the heat-resisting ring 1 so as to form the mounting hole 22 penetrating through the mounting ring 23, and the alloy material enters the blocking groove 11 of the heat-resisting ring 1 so as to form the blocking rib 28 in the mounting ring 23; alloy material enters a cavity between the first die-casting ring surface 32 and the second die-casting ring surface 42 so as to form the smooth wheel body 21 of the alloy aluminum wheel and make two surfaces of the wheel body 21 smooth; the alloy material enters the first annular chamfer 33, the second annular chamfer 43, and the cavity between the die cast rings to shape the wire guide 27.

After the alloy material is cooled, the heat-resisting ring 1 is die-cast with the wheel body 21 into a whole. In the step, the die casting machine separates the front die core 3 from the rear die core 4, and simultaneously separates the two loose cores 5 by utilizing the inclined guide columns, so that the die cavity is opened, and the ejector pins are used for ejecting a plurality of alloy aluminum wheel blanks, so that the alloy aluminum wheel blanks can be demoulded.

Specifically, step S5 includes:

And the finished alloy aluminum wheel after being processed is used as a wire guide wheel.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
