A device and application of ultrasonic-assisted lost foam casting magnesium-aluminum bimetallic casting

Abstract

The invention belongs to the technical field of metal casting manufacturing, and in particular relates to a device and application of an ultrasonic-assisted lost foam casting magnesium-aluminum bimetallic casting. The ultrasonic-assisted lost foam casting magnesium-aluminum bimetallic casting device of the present invention comprises a lost foam casting composite model, an ultrasonic vibration component and a sand box, and the lost foam casting composite model includes a gating system, a casting model connected with the gating system, an embedded A solid inlay in the casting model; the ultrasonic vibration assembly includes a connector, a transducer holder detachably connected with the connector, an ultrasonic transducer detachably connected with the transducer holder, and an ultrasonic transducer Ultrasonic generators connected electrically. The invention can break and remove the oxide film on the surface of the aluminum inlay through the cavitation of the ultrasonic wave, eliminate the inclusion defect at the interface, and can also break the dendrites and refine the grains, thereby improving the quality of the magnesium-aluminum bimetallic material. organizational performance.
