Abstract:
Aiming at the injection mould process parame-ter optimization methods are relatively few, and there is no combination of multiple multi-objective optimi¬zation methods to carry out optimization research. In this paper, the gating system of the upper bracket of automobile front-end frame is designed, and the flow channel system of the upper bracket of automobile front-end frame is simulated. The orthogonal experi¬ment of the upper bracket of automobile front-end frame is designed. The multi-objective injection mould process parameters of the parts are optimized by the grey relational analysis (GRA) method, and the optimal process parameters and the influence degree of each factor on the evaluation index are obtained. The second-order response surface model of the eval¬uation index was established with the key influencing factors, and the multi-objective optimization of the model was carried out with the genetic algorithm, and the optimal injection mould process parameters of the parts were obtained. The upper bracket of automobile front-end frame optimized by the design was physi-cally injected. The feasibility of the optimization method of injection mould process parameters was verified.
