The foaming equipment comprises a workbench, a mounting frame is fixedly mounted on the top side of the workbench, and two multi-layer gear rings are rotatably mounted on the top side of the mounting frame; circular shafts are fixedly mounted on the inner walls of the two sides, away from each other, of the mounting frame correspondingly, and fixing rings are fixedly mounted at the ends, close to each other, of the two circular shafts correspondingly. A rotating disc is rotated to drive an adjusting lead screw to rotate, the adjusting lead screw rotates to drive a U-shaped block to move, the U-shaped block moves to drive a lantern ring to move, the lantern ring moves to drive two gears to slide on the two multi-layer gear rings through a rotating shaft, and therefore injection proportion of two raw materials is adjusted by adjusting transmission ratio of rotation of the two multi-layer gear rings, the best foaming effect can be achieved by finely adjusting the proportion according to different shapes, strengths and functions of foaming forming, foaming effect of the foaming equipment is good, and performance of the formed polyurethane foam plastic is good.
