Optimization for injection molding process of automobile battery shell based on orthogonal experiment
The simulation for mesh division and injection molding process of an automobile battery shell was carried out by Moldflow software.Holding pressure,cooling water temperature,holding time and cooling time were selected as the four factors of the orthogonal experiment,and three levels were selected for each factor to design the orthogonal experiment.The results show that the optimal process parameters are as follows:the holding pressure is 60 MPa,the cooling water temperature is 22℃,the holding time is 25 s,and the cooling time is 30 s.The total warping deformation is reduced by 2.491 3 mm than that of traditional design under the conditions.The quality problem that thin wall parts is easily warped and deformed is solved effectively by adjusting the cooling water channel.
