On June 3, 2026, information from the State Intellectual Property Office showed that Shandong Haomai Machinery Technology Co., Ltd. successfully applied for a patent called “A Tire Active Mold”. The authorization announcement number is CN224296653U, and the authorization announcement date is May 29, 2026.
The patent application number is CN202520754838.3, and the application date is April 21, 2025.
The patent summary shows that this tire movable mold belongs to the field of tire movable mold technology and is mainly composed of an upper cover, upper slider, slider, guide bar, guide ring, base and other parts.
Five friction pairs are formed by sliding fit between the upper cover and the upper slider, between the upper cover and the slider, between the slider and the guide ring, between the slider and the guide bar, and between the slider and the base.
Furthermore, a braided layer is fixedly provided on at least one friction surface of at least one friction pair, and the braided layer is braided from polytetrafluoroethylene fibers and aramid fibers.
This braided layer has high wear resistance and low friction coefficient, which significantly increases its use time on the mold, eliminating the need for replacement of the braided layer during the life cycle of the mold, and greatly reducing production costs.
