| Abstract: |
| An analysis of motional andmechanical characteristics for twin toggle，three links and five diagonal hinges mold closing device is made by structural method and using diagonal as variable.The formulas for calculating the mold board stroke，the oil cylinder stroke，the speed variation coefficient，the mold closing force and the force amplification are derived and the direct calculating method for primary angle and critical angle is described.The theoretic basis of optimizing the mold closing device design and establishing the mathematic model for the optimized design is proposed. |
