Aluminum alloy casting stamping die with noise reduction performance

The invention is suitable for the technical field of stamping dies, and provides an aluminum alloy casting stamping die with noise reduction performance, which comprises a convex die piece fixedly mounted on an external press machine and a noise reduction assembly, the noise reduction assembly comprises a noise reduction cylinder with the two ends open. A female die piece is arranged between the two sliding rods in a sliding mode. The female die piece comprises a containing box arranged in the noise reduction cylinder in a sliding mode. Liquid leakage holes are uniformly formed in the surface of the containing box; lifting plates in sliding fit with the sliding rods are symmetrically fixed to the peripheral side face of the mounting pipe, and an extension plate is fixed to the peripheral side face of the mounting pipe and located between the two lifting plates; an extrusion spring is fixed between the second piston and the mounting pipe; according to the device, along with gradual increase of the noise reduct
