轿车子午线轮胎侧缺胶的研究

Research on the lack of rubber on the sidewall of radial tires for cars

分析轿车子午线轮胎侧缺胶易发生部位及产生的原因,并提出相应的解决措施。通过适当调整缺胶部位的材料分布、重新设计半部件尺寸、在模具增加排气孔等措施,能够有效解决侧翼端点附近、三角胶端点附近及胎侧小字体等胎侧缺胶病象,有效提高了外观检验通过率并简化了工艺流程,提升了公司的利润。

This paper analyzes the car radial tire tire sidewall glue is prone to parts and causes,and puts forward the corresponding measures to solve the problem.Through the appropriate adjustment of the distribution of materials in the lack of rubber parts,redesign the size of parts,increase the air vent in the mold and other measures,can effectively solve the following problems,such as the lack of rubber near the end point of the flanks,the lack of rubber near the end point of the triangle rubber and the font of the tire side is small and other phenomena.These measures effectively improve the passing rate of appearance inspection and simplify the process flow,which enhances the company's profit.
