A rolling bearing cage electromagnetic radial impact semisolid extrusion die

A rolling bearing cage electromagnetic radial impact semi-solid extrusion die, the extrusion apparatus comprising a stopper rod, the die set means, electromagnetic means and the radial impact movable mold apparatus, the mold apparatus in which the internal fixed stopper rod fitted with a pressing device, means fixedly connected outer mold fixed electromagnetic radial impact means, on a given side die means is movable mold apparatus. In use, the prepared semi-solid billet into a preheated mold cavity, and then decreased movable mold clamping apparatus, the pressing means pressing the stopper rod by the semi-solid billet for filling, packing and molding the first bearing holder, then open the solenoid first radial impact device for radial electromagnetic bearing cage and forming a second impact bearing cage, and finally, rises movable mold parting means, pressing means and increase the second bearing ejector holder, the present invention has a simple, high forming efficiency advantages.
