| Abstract: |
| The base of traditional four pillar plate vulcanizing machine was made from cast iron and the pull ring was usually formed under the level of casting gate entry point.Due to the improper distribution of material， the tensile strength of pull ring was low，which resulted in easy fracture of pull ring.In this study，the stress distribution of pull ring was analyzed through conventional stress analysis and ANSYS modeling analysis，considering the cases that pull ring position was under and above the level of gate.The analysis results showed that since the tensile strength of the cast iron was much lower than the compression strength，when the pull ring was formed above the level of the gate，the stress distribution of pull ring was improved and the easy fracture was prevented. |
