Based on the analysis of software Moldflow through orthogonal experiment and get the best technical parameters. Using PRO/E 3d modeling software will plastics 3d drawing, reintroduce Moldflow simulation software, for the best gate location analysis. Reference analysis of the best gate location, design gating system of Pro/E EMX formwork design plugin import formwork system and the detailed design, mould parts of the structure, combining the engineering drawings Pro/E AutoCAD software modules and draw the part of the mould assembly, and finally through Pro/E of the assembly simulation module design good mold cavity, simulation, plastic mould set of mould process, examination without interference phenomenon, mould movement to ensure that the design of the mould in practical production. Finally using Moldflow of plastic parts for molding process simulation, through orthogonal test method, test data, the comprehensive evaluation in the test range process parameters on the effect of injection warping deformation, thus obtains the optimal parameters.
