Reusable tire mold manufacturing method based on additive manufacturing technology

Abstract

The invention discloses a reusable tire mold manufacturing method based on an additive manufacturing technology. The reusable tire mold manufacturing method comprises the following steps that blockingis performed on a single tire mold, the single tire mold is divided into an additive manufacturing body and a machining base body, the additive manufacturing body is machined through an additive manufacturing process, the machining base body is machined through a traditional manufacturing process, the single tire mold and the machining base body are combined through mechanical connection, and tire molding is finally realized; under the drive of three-dimensional drawing software, layer-by-layer melting is performed or metal powder is synchronously fed, so that an additive manufacturing body with complex patterns is produced; an original additive manufacturing body is separated from the machining base body; and then the new additive manufacturing body is connected to the original machiningbase body to be assembled into a single whole mold, and accordingly the whole set of mold is assembled. By the adoption of the reusable tire mold manufacturing method, the production link is more efficient, and compared with a traditional machining method, the reusable tire mold manufacturing method is more energy-saving and environmentally-friendly; and meanwhile vulcanizing of tires with different types of patterns is more convenient and faster, the machining base body can be reused, and thus the production and manufacturing costs are saved.

Description

technical field [0001] The invention relates to a novel tire mold manufacturing method, in particular to a tire mold manufacturing method combining an additive manufacturing body and a reusable base body through a detachable mechanism, and belongs to the field of advanced manufacturing. Background technique [0002] Dies are widely used in various fields of national economy. Throughout the development history of molds, from the initial pure hand-made, to mechanical processing, to the digital design and CNC machining of automatic control molds that are commonly used today, the precision and complexity of molds are getting higher and higher, and the cost and production cycle are gradually increasing. reduce. With the rapid development of my country's automobile industry, the manufacturing level of tire molds and tires has also made great progress. The rapid upgrading of the automobile tire industry has stimulated the continuous growth of the tire mold market. Tire mold is vu...
