Authorized document number: CN 103407035B Authorization date: August 19, 2015 Patentee: Shandong Hammer Machinery Technology Co., Ltd. Inventors: Zhang Wei, Zhang Ren, Ma Haibo The present invention provides a dual-damascene composite structure without Stomatal tire active mold, block and preparation method. The block includes a first metal block body and a second metal material member embedded in the inner circumferential surface of the pattern. The block is provided with an exhaust passage which communicates with the inner circumferential surface and the outside of the cavity to form a dual damascene composite structure The non-stomatal tire active mold blocks. Among them, the first and second metal materials are both suitable for tire vulcanization, and the first metal material
