| 中文摘要: |
| 针对叉车用充气式实心橡胶轮胎快装式共锁圈（LOC）胎圈裂口问题进行原因分析，对轮胎的模具钢圈进行优化设计。结果表明，通过将模具钢圈右侧胎踵处由下模改到上模和增加环形凹槽等优化设计，消除了轮胎硫化出模时右侧胎踵受力，可使右侧胎踵胶料迅速充满模腔，解决了胎圈部位裂口问题，提高了产品质量和生产效率。 |
| 英文摘要: |
| Aiming at the cracking of the LOC bead of the pneumatic solid rubber tire for forklift，the reasons was analyzed，and the optimization design of the mold steel ring of the tire was carried out.The results showed that by changing the right heel of the mold steel ring from the lower mold to the upper mold and adding annular grooves，the force on the right heel when the tire was vulcanized and out of the mold was eliminated，the right heel compound could quickly fill the mold cavity，which solved the problem of cracks of the tire bead，and improved product quality and production efficiency. |
