The invention discloses a novel powder forming machine die. The novel powder forming machine die comprises a die body. A die set is arranged at the top end of the die body. The die set is composed ofan upper die and a lower die. A clamping groove is arranged in the middle of the front side of the die set. A sealing ring is arranged at the top end of the inner side of the lower die. A gas cylinderand an installation rack are arranged in the middle of the interior of the lower die. The novel powder forming machine die is provided with a long baffle and a short baffle. When the die is in use, powder is pressed by a powder forming machine, a silencer starts up, noise generated in the production process enters the silencer, and sound waves are continuously reflected by the long baffle and theshort baffle; and because the surface of the long baffle and the surface of the short baffle are uneven, energy is consumed in the reflection process of the sound waves, residual sound waves will bereflected again when passing through a smooth separation plate so as to be consumed, and the sound wave pollution caused by the noise to the environment is reduced.
