Polyurethane forming and punching integrated structure

The polyurethane forming and punching integrated structure comprises an upper die core and a lower die core which are correspondingly arranged up and down, a die cavity is formed between the upper die core and the lower die core, an upper die knife edge insert is installed on the upper die core, and a lower die knife edge insert is installed on the lower die core. The upper die knife edge insert and the lower die knife edge insert are both located on the outer side of the edge of the die cavity and matched with each other in position, and the upper die knife edge insert and the lower die knife edge insert are both subjected to hardening treatment. According to the polyurethane forming and punching integrated structure, the knife edge inserts are arranged on the upper mold core and the lower mold core, and the upper mold knife edge and the lower mold knife edge are hardened, so that polyurethane can be synchronously punched during forming, the machining procedures are reduced, the cutting rate of the mold is i
