Abstract

The invention discloses a manufacturing process of a wearing plate for an automobile tire mold. After matching copper-tin powder, molybdenum disulfide, lead powder and graphite powder, and after the high-temperature sintering and molding through a powder metallurgy sintering furnace, the hardness of the wearing plate is improved greatly, 0.5-0.6Wt% aluminum borate crystal is added to enhance the sintering effect, the sintering furnace is heated and warmed up, the heating rate is controlled to 40- 50 DEG C/min, and then the aluminum borate crystal is heated and warmed up to 700- -750 DEG C to be kept for 3 hours, so hardness of the wearing plate is gradually improved, and finally the rust removal treatment is performed, so that the wearing plate has better rust resistance, and the service life is prolonged. The manufacturing process solves the problems of weak hardness and easy rust of the existing wearing plate.

Description

technical field [0001] The invention relates to the technical field of wear-resistant plate processing technology, in particular to a wear-resistant plate manufacturing process for automobile tire molds. Background technique [0002] The wear-resistant plate for tire mold is the key part of the positioning and sliding between the active mold for modern tires, the movable plate and the fixed ring. It mainly plays the role of positioning, and because the movable mold has been working continuously at a higher temperature for a long time, to keep the movable mold open normally, the material needs to have a stable thermal expansion coefficient and wear resistance, and the powder metallurgy bimetallic wear-resistant plate can completely meet its needs. The wear-resistant plate can reduce the damage to the mold during the vulcanization process of the tire. However, the existing wear-resistant plate has weak hardness and is easy to rust. Therefore, we have designed a wear-resistant...
