| 中文摘要: |
| 斜平面模具中套滑板在模具闭模时起到锁紧模具作用,中套滑板的磨损过大会导致锁模力不足或消失,引起模具花纹块之间、花纹块与上下侧板之间产生间隙,硫化时轮胎出现胶边。通过对特定滑板的磨损分析,建立了该滑板磨损模型。根据磨损模型及计算机有限元模拟,轮胎胶边的产生主要是由于模具预加载量消失造成的。对全钢模具1188壳体而言,模具工作8000次左右时,中套滑板的磨损量会导致模具预加载量消失。 |
| 英文摘要: |
| The cone ring sliding plate mold set to locking mold in the mold closing action, If the sliding plate was worn too much, the mold’s locking force would be less than requirement or even disappears, which would cause gaps between segment and sidewall plate or between segment and segment. Then rubber edge would appear on the surface of the tire after vulcanization. Based on the analysis of the wear, the wear model was established. According to the wear model and the finite element simulation of the computer, flash of the tire is mainly caused by the loss of the mold pre loading. For TBR mold 1188 shell, the mold works about 8000 times, the wear of the sliding plate will lead to the loss of mold preload. |
