轮胎模具及其排气装置、花纹部分及模具清洗方法
摘要：
本发明提供了一种轮胎模具及其排气装置、花纹部分及模具清洗方法，该排气装置用于设置在所述轮胎模具的花纹部分中，所述花纹部分设有第一排气通道，所述排气装置形成有第二排气通道，所述第二排气通道包括微气隙结构，形成在轮胎硫化过程中排气不跑胶的排气间隙，所述第二排气通道的第一端与所述花纹部分的第一排气通道相连通，所述第二排气通道的第二端延伸至所述花纹部分的内周面，与所述轮胎模具的内腔相连通。本发明提供的排气装置在进行硫化的过程中，使轮胎硫化过程产生的气体通过第二排气通道进入花纹部分中设置的第一排气通道，再通过第一排气通道将气体排到轮胎模具的外部，并且在第二排气通道中设置的微气隙结构能够在轮胎硫化过程中实现排气不跑胶。
摘要（英）：

The invention provides a tire mold and an air exhaust device, a pattern part and a mold cleaning method thereof. The air exhaust device is arranged in the pattern part of the tire mold; the pattern part is provided with a first air exhaust channel; a second air exhaust channel is formed in the air exhaust device; the second air exhaust channel comprises a micro air-gap structure and is formed in an air exhaust clearance in which air exhausts and rubber can not leak in the tire vulcanization process, the first end of the second air exhaust channel is communicated with the first air exhaust channel of the pattern part, and the second end of the second air exhaust channel extends to the inner peripheral surface of the pattern part and is communicated with the inner cavity of the tire mold. The air exhaust device provided by the invention has the benefits that in the vulcanization process, gas generated in the tire vulcanization process enters the first air exhaust channel formed in the pattern part through the second air exhaust channel and is discharged to the outside of the tire mold through the first air exhaust channel; through the micro air-gap structure formed in the second air exhaust channel, the effects that air exhausts and rubber cannot leak can be realized in the tire vulcanization process.
