This paper proposes a design methodology to decide layouts and shapes of cooling channels in a plastic injection molding die for reduction of residual stresses in plastic products. In a cooling process of plastic injection molding, non-uniform temperature distribution causes some molded defects in molded products such as warps and cracks. The most effective factor to affect the temperature distribution is cooling channels. In the proposed method, the design problem of cooling channels is formulated as shape optimization problem considering the residual stresses in a plastic product as an objective function. Then, the layout parameters of cooling channels are taken as the design variables and the residual stresses in a plastic product are minimized.
