| Summary: | 碩士 === 國立高雄應用科技大學 === 模具工程系碩士班 === 102 === This study aim to existing plastic injection mold that ejection-clamping mechanism of two-freedom and double-toggle creative design various and feasible ejection-clamping mechanism of one-freedom. This paper recount structural analysis of original ejection-clamping mechanism firstly, and doing kinematic analysis by AutoDesk Inventor mechanism simulation software. The result of kinematic analysis get design condition and requirement of this study that design three ejection-clamping mechanism of much practical, low cost, simple structure and maximum ejection stroke. The first type is (8,10) mechanism that add movable link to attach between toggle link and movable ejector plate of clamping mechanism, and its concept is from four-bar linkage. The second type is (10,13) mechanism that add a (6,7) linkage to attach between toggle link and movable ejector plate of clamping mechanism, and its concept is from Robert’s straight line mechanism. The third type is (10,13) mechanism that add a (6,7) linkage to attach between toggle link and movable ejector plate of clamping mechanism, and its concept is from Hoeken straight line mechanism. This study use triangle geometry analytic method by Mathematica software and vector-loop numerical analysis by Matlab software that determine ejector stroke, and simulate by AutoDesk Inventor mechanism simulation software.
