AI Technical Summary

Technical Problem

The white rubber flow channel in the existing white tire side pre-die adopts an integrated design, which leads to low die processing efficiency and requires repeated adjustments to achieve the desired molding effect.

Method used

A combined white tire sidewall pre-die structure is adopted, and the assembly is fixed on the through groove by bolt assembly, forming a fourth flow channel for the white rubber sidewall rubber material to flow, allowing direct processing on the through groove to adjust the die shape.

Benefits of technology

The efficiency of white rubber sidewall molding is improved, the number of adjustments is reduced, faster molding speed and larger processing surface are achieved, and predetermined molding requirements are met.

Abstract

The utility model is suitable for a tire forming pre-die technology, and provides a combined type white sidewall pre-die, which comprises a pre-die body comprising a first end surface, a second end surface, a top surface and a bottom surface, a main rubber material channel for forming a tire side main rubber surface is arranged between the first end surface and the second end surface, and a through groove for constructing a white rubber tire side runner is formed in the top surface; the through groove is communicated with the first end surface and the second end surface; and the assembly is assembled on the end face, away from the bottom face, of the through groove, and a gap between the assembly and the through groove forms a fourth runner used for forming flowing of the white rubber sidewall rubber. Compared with an integrated pre-die, the combined part and the through groove can obtain a larger processing surface, the adjustment progress of the shape of the die opening of the fourth runner can be accelerated, and the adjustment times are reduced, so that the white rubber sidewall rubber type forming speed is higher, and the preset forming effect is achieved.
