Abstract

The invention relates to a production process for tire curing bladders. The production process includes steps of (1), pouring butyl rubber, zinc oxide, stearic acid, curing resin, N220 carbon black, N550 carbon black, caster oil and stabilizers into an internal mill and then milling to obtain milled rubber materials; (2), filling the milled rubber materials into an open mill, mixing the milled rubber materials to discharge to obtain rubber sheets 10mm in thick and 50mm in width, and naturally cooling the rubber sheets to the room temperature; and (3), filling the rubber sheets into a screw of an injection press while keeping the temperature of the screw within the range of 70-80 DEG C, extruding the rubber sheets by the screw under the pressure ranging from 12 MPa to 18MPa, weighing the rubber sheets by a metering pump, feeding the rubber sheets into a mold cavity, holding the pressure ranging from 12MPa to 18MPa to perform injection curing for 42-48 minutes at a temperature ranging from 160 DEG C to 170 DWG C, and finally ejecting the formed bladders out of the mold cavity by the injection press after finishing curing. Service times of the bladders produced by the production process can be increased, service lives of the bladders can be prolonged, and quality of tires produced by the aid of the bladders can be improved remarkably.

Description

technical field [0001] The invention relates to a production process of a tire curing bladder, which belongs to the technical field of automobile tire production. Background technique [0002] With the continuous development of the world's automobile industry and the rapid growth of global highways, there are more and more types of cars, faster and faster driving speeds, and higher and higher quality requirements for tires. Therefore, the quality requirements for tire molds are also getting higher and higher. Get better and better. Tire curing bladders are an essential tool in the vulcanization process in modern tire production. Tire curing bladders are subject to some harsh operating conditions, including high temperatures, extensive flexing, co-vulcanization, and migration of curing agents from unvulcanized green tires. The service life of the vulcanizing bladder has a great influence on the production efficiency of the tire factory. The function of the tire vulcanizing ...
