High-density polyurethane foaming mold

The high-density polyurethane foaming mold comprises a bottom plate, a box body is fixedly installed on the top side of the bottom plate, a first air cylinder is fixedly installed on the top side of the box body, the output end of the first air cylinder penetrates through the box body and is fixedly provided with a first piston rod, and the output end of the first piston rod is fixedly connected with an upper push plate. An upper pressing plate is fixedly mounted on the bottom side of the upper push plate, four grooves are formed in the upper pressing plate, and through the four grooves formed in the upper pressing plate, when large-size foaming needs to be carried out, two hand wheels rotate to drive shaping plates arranged on one sides of two threaded rods to be far away from each other and then move to the positions below the two grooves located in the two sides of the upper pressing plate, so that foaming of the large-size foaming needs to be carried out. When foaming is carried out, a first air cylinder
