| Abstract: | The factors affecting the stress warpage deformations about thin-walled part in the plastic injection forming were analyzed,a numerical simulation mathematical model and solving method about the warpage deformation of injection forming plastic were given.Based on it,effects of various mould designs and forming process conditions on the degree of warpage deformations of thin-walled optical disk bracket in injection forming was simulated.According to the simulation result,it was analyzed that flowing unequilibrium and cooling unequilibrium were the key factors affecting the stress warpage deformations when the raw materials and the structure of part were confirmed,the solving method for stress warpage deformations were given. |
