Abstract

The invention discloses a manufacturing method of a pattern ring of a segmented mold of a radial tyre. The manufacturing method comprises the following steps of: performing a CAD design on the pattern ring, establishing a 3D model of the pattern ring, then dividing the 3D model into corresponding single pattern blocks according to requirements, and simultaneously customizing a pattern ring blank, finishing preliminary works such as rough machining, heat treatment, reference plane machining and the like of the pattern ring; configuring a plurality of machine tools and completing the preparation work before production; establishing part processing cutter tracks required by each machine tool, generating semi-finishing, finishing and corner cleaning procedures of each pattern block according to the configured condition of the machine tools, and establishing a procedure list; executing the processing procedures according to a procedure list sequence; and assembling and debugging the plurality of processed pattern blocks. The manufacturing method has the advantages of simple process, difficult generation of thermal deformation on a workpiece during production, short production cycle, high production efficiency and high accuracy, and ensures the assembly accuracy of the a tyre mold.

Description

technical field

[0001] The invention relates to the technical field of molds, in particular to a method for manufacturing a pattern ring of a radial tire active mold. Background technique

[0002] At present, the radial active mold is composed of four major parts: upper and lower tire side plates, pattern rings, and centripetal mechanisms. The pattern ring, the upper side plate and the lower side plate are combined into a mold cavity to ensure the tire shape and tire design parameters; the centripetal mechanism ensures that the mold cavity combination reaches the design accuracy and interfaces with the tire vulcanizing machine to coordinate with the movement of the vulcanizing machine. Complete the vulcanization and shaping of the tire. Among them, the pattern ring is the core part of the tire mold, and the complex and changeable tire specifications and pattern forms are the key factors affecting the quality and production cycle of the tire mold.

[0003] At present, the p...
