Through the mixing and stirring tank, the first motor, the stirring shaft and the vibration motor arranged in the injection molding machine unloading and mixing device, the materials inside the mixing and stirring tank can be mixed and stirred by shaft stirring and vibration stirring, so that the mixing and stirring effect of the materials inside the mixing and stirring tank can be better, and when unloading, the inner wall of the mixing and stirring tank can be vibrated by the U-shaped structure of the mixing and stirring tank and the vibration motor, so that the material can slide downward along the inner wall of the mixing and stirring tank, thereby making the unloading speed of the mixed material smoother and faster.
