Abstract

The invention discloses an automotive trim panel injection moulding technology based on a BP (Back Propagation) neural network. The automotive trim panel injection moulding technology comprises the following steps: establishing a plastic part mold flow CAE (Computer Aided Engineering) analysis model; simulating the injection moulding technical parameters of the plastic part, and determining technical parameters which can be set; preliminarily optimizing the optimum value domain, which is improved on the basis of buckling, of each technical parameter; carrying out prediction model training on an obtained experiment result by the BP neural network to obtain a prediction model; and on the basis of the optimum value domain, designing a quadratic stereo orthorhombic optimum value domain optimization scheme, applying the neural network model to predict, and directly optimizing an optimal parameter domain value. The automotive trim panel injection moulding technology aims at the problem of large buckling deformation during CAE analysis when injection imoulding is carried out, the minimum buckling and the optimal injection moulding technical parameters of the plastic part are optimized, practical injection moulding mold testing frequencies and mold testing cost are lowered, workload is lowered, and working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a BP neural network-based injection molding process for automobile interior panels. Background technique [0002] After the injection molding of automotive interior panels, large warping deformation often occurs. If the large warping deformation is not resolved, it is necessary to conduct a comprehensive analysis of various factors in the injection molding process and related process parameters. Work Larger volume, lower efficiency.
