Synchronous knockout tire mold
By using a flexible tire mold design that allows for simultaneous mold opening and material ejection, the mold opening and demolding actions are synchronized, solving the problems of low tire production efficiency and unstable quality in existing technologies. This improves production efficiency and molding quality, while reducing mold wear and production costs.

AI Technical Summary
Existing flexible tire molds require separate steps for mold opening, tread block demolding, and tire unloading, which prolongs the single vulcanization molding cycle of the tire. Furthermore, insufficient coordination of the actions may lead to uneven stress during tire demolding, resulting in appearance defects.
Design a flexible tire mold with synchronous mold opening and material discharge. By setting a split structure of upper mold cover, cavity mold and lower mold base, and using the linkage of axial drive component and radial drive component to realize the synchronous mold opening and demolding action, combined with limit component and adjustment component, it is ensured that the tire is directly discharged after the mold is closed.
It shortens the molding cycle, improves production efficiency, ensures the molding quality and precision of tires, reduces mold wear, and lowers production costs.
