Abstract

Through numerical simulation method which combined Moldflow software with orthogonal experiment,the residual stress distribution after demoulding in the thickness direction of three typical positions of polycarbonate corner window plastic parts was studied, and the injection compression molding process of corner window plastic parts was optimized. On the basis, the main factors were selected to investigate the influence of the main process parameters on the residual stress of the product.The results showed that the residual stress distribution after demoulding in the thickness direction of three typical locations of the product conforms to the three-region distribution of tension-compression-tension.The optimum combination of process parameters was that the mold temperature was 105 ℃, the melt temperature was 315 ℃, the injection time was 3 s, the compression force was 882 kN, the compression distance was 1.0 mm, the compression speed was 5 mm/s, and the delay time was 0 s.Melt temperature, delay time, compression distance were the main process parameters that affect the residual stress of the product, and the residual stress of the subsurface layer and the center layer of the plastic part decreased with the increase of the melt temperature, while the residual stress of each layer in the thickness direction of the plastic part increased with delay time and compression distance.
