Abstract
In current designs of the conventional and Fanuc five-point double-toggle mechanisms, the lengths of moving-platen side links are greater than the lengths of tailstock-platen side links in order to provide enough horizontal space for the ejector unit and to avoid the unsound transmission characteristic. In this study, another method to provide such a space is adopted. From a parametric study, the method can be proved practicable and the individual profiles of toggle linkages for the two types of mechanism with the characteristics of time saving or a larger opening stroke and/or thrust saving can be found. Moreover, objective comparisons of the performances between the two types of mechanism are also given.
