| 中文摘要: |
| 针对轨道车辆用纵向止挡橡胶部件设计橡胶冷流道注射成型模具及硫化工艺，并通过正交试验方法对塑化温度、料筒温度、一段注射速度、冷流道温度4个工艺参数对产品自由高度及刚度的影响规律进行研究。结果表明：工艺参数对产品自由高度（或收缩率）影响由大到小的排序为塑化温度、料筒温度、一段注射速度、冷流道温度，而对产品刚度影响由大到小的排序为料筒温度、塑化温度、冷流道温度、一段注射速度。本研究可为橡胶冷流道注射成型工艺的推广应用提供参考。 |
| 英文摘要: |
| The rubber cold runner injection molding mold and vulcanization process were designed
for longitudinal bump stop rubber parts used in rail vehicles，and the influence of the process parameters
including plasticizing temperature，barrel temperature，primary injection speed and cold runner temperature
on the free height and stiffness of the product was studied through orthogonal test methods. The results
showed that the influence of process parameters on the free height（or shrinkage） of the product was sorted
from large to small as plasticizing temperature，barrel temperature，primary injection speed and cold runner
temperature，while the influence on the stiffness of the product was sorted from large to small as barrel
temperature，plasticizing temperature，cold runner temperature and primary injection speed. This study could
provide a reference for the promotion and application of the rubber cold runner injection molding technology |
