[0002] Polyurethane, the full name of which is polyurethane, is a general term for macromolecular compounds containing repeating carbamate groups (NHCOO) on the main chain. It is formed by the addition polymerization of organic diisocyanates or polyisocyanates with dihydroxy or polyhydroxy compounds. In addition to carbamate, polyurethane macromolecules may also contain ether, ester, urea, biuret, allophanate and other groups. Depending on the raw materials used, products with different properties can be produced, generally of polyester and polyether types. They can be used to manufacture plastics, rubber, fibers, rigid and flexible foam plastics, adhesives and coatings, etc. Molds are required to assist in the production of screen-type polyurethanes.

[0003] For example, Chinese patent publication number CN203046096U discloses a mold specifically designed for integrally forming a polyurethane fine screen.
