Rubber roller forming mold and processing method thereof

Abstract

The invention provides a rubber roller forming mold and a processing method thereof. The mold includes a mold body, and a cavity is formed in the mold body. The cavity includes a first cavity body anda second cavity body communicating with each other. The inner diameter of the first cavity body is smaller than the inner diameter of the second cavity body, the inner wall of the first cavity body is a curved surface, and the mold body is provided with a feeding port. According to the scheme, the forming of rubber rollers at one time is facilitated, the subsequent processes of rubber roller production and processing are reduced, the processing efficiency and the processing quality of the rubber rollers are effectively improved, the structural strength of the rubber rollers is effectively improved, the risk of degumming is reduced, the connection strength between a hard rubber layer and a soft rubber layer is improved, the glossiness of the surfaces and the concentricity of the rubber rollers are improved, and the service life of the rubber rollers is effectively prolonged.

Description

technical field [0001] The invention relates to rubber roller processing equipment, in particular to a rubber roller forming mold and a processing method thereof. Background technique [0002] Cots are used in drawing frames, rovings, and spinning frames in the cotton spinning industry. During the spinning and drafting process, the cots are responsible for controlling the movement of fibers, reducing the speed change of floating fibers, improving yarn evenness, and reducing yarn thickness and hairiness. [0003] The existing rubber roller manufacturing process generally cannot meet the requirements of use after rubber vulcanization, and the concentricity and straightness of the circles deviate. process, low production efficiency and high production cost. [0004] Patent No. CN208006175U discloses a rubber roller injection molding mold, including a main body, a shaft core is provided inside the main body, an upper module is provided on the top of the shaft core, a lower mod...

AI Technical Summary

Problems solved by technology

However, during the processing of this model, there are extrusion marks on the surface of the rubber roller, and the gloss or smoothness does not meet the requirements for use, which affects the product quality. At the same time, it needs subsequent grinding and polishing, which cannot be formed at one time, which affects the processing efficiency of the rubber roller.
