company news about What are the advantages of the precision forming device and forming process for magnesium alloy automobile hub?

The company develops a magnesium alloy automobile wheel precision forming device and its forming process. The invention solves the problems of shrinkage porosity, shrinkage hole, cold separation and coarse crystal grain existing in the existing magnesium alloy wheel hub in the casting process, including Upper Die Assembly and Lower Die Assembly, the utility model is characterized in that the upper die assembly is provided with a push-pull oil cylinder which is perpendicular to the action direction of the die, and the push-pull oil cylinder is connected with the upper die connecting seat plate, and the upper die head is fixed at the lower part of the upper die connecting seat plate; the Lower Die Assembly is provided with a forming area and a demoulding area, the forming area comprises a forming slide block and a lower mould core. The forming slide block is arranged in a barrel-shaped mould bed, the outer surface of the barrel-shaped mould bed is provided with a barrel-shaped heat preservation device, and the demoulding area is provided with a ejector mechanism. Less machining allowance, simple process, easy to operate, fine grain wheel, high strength, good stiffness.
