| 中文摘要: |
| 以采用注压成型工艺生产锥形橡胶弹簧为例，研究硫化内压对锥形橡胶弹簧外观质量和物理性能的影响。结果表明：锥形橡胶弹簧硫化时胶料用量增大，硫化内压增大，锥形橡胶弹簧的压缩高度和垂向刚度增大，但胶料用量过大会影响产品外观质量；硫化内压增大，锥形橡胶弹簧的耐屈挠疲劳性能、抗蠕变性能以及金属-橡胶粘合强度提高，产品综合性能改善。 |

| Abstract：Taking the conical rubber spring produced by injection molding process as an example，
the effect of vulcanization internal pressure on the appearance quality and physical properties of the
conical rubber spring was studied. The results showed that，for the conical rubber spring vulcanization，if
the amount of the compound increased，the vulcanization internal pressure increased，and the compression
height and vertical stiffness of the conical rubber spring increased，but the excessive compound would affect
the appearance. With the increase of vulcanization internal pressure，the flexural fatigue resistance，creep
resistance，metal-rubber bonding strength of the conical rubber spring were improved，and the comprehensive
performance was better. |
