碩士 === 逢甲大學 === 機械工程學所 === 93 === In this work, high-velocity air is conducted into the cooling channel with honeycomb section instead of water to observe the effect of air coolant on the uniformity and maximum deformation and cooling cycle of an injected part during injection molding of polymer. Herein, a novel cooling methodology is proposed by using a new cooling channel with enhanced honeycomb sectioned structure. Due to relatively higher surface area, the enhanced honeycomb channel provides an alternative selection of cooling system for injection molding. The deflection characteristics of the enhanced honeycomb structure under higher pressure and the feasibility of air coolant for injection molding are analyzed. Consequently, a favorable methodology based on the optimized processing parameters for improving the quality and cost of injected product is presented.
