Simulation Design And CAE Optimization Analysis Of Big-size Injection Mold Based On UG

Referred to a large number of literature resource of design and application of large-scale injection molds , analyzed the development status of domestic and international injection mold. Aiming at the problems of mold CAD /CAE summarized the development trend of plastic injection molds.Described the molding process and principle of injection molding molds, introduced the basic structure of injection molds in detail,summarized the design features in addition,paves the way for the three-dimensional design of the injection mold and their parts,then details the impact that all kinds of processing parameters on the plastic product,prepares the theoretical basis for the optimization of processing parameters.Using the Mold Flow analysis software,analyzes the gate location of large plastic product. According to the result,makes three schemes for flow analyzes. By comparing the results,determines the optimum gate number.Using the Mold Flow/Warp module,analyze the warp of the products; find the main parameters of the warp follow the results. In order to minimize warping deformation,determine the optimum process parameters,according to rheological design analysis,repeated by changing the molding process parameters,design the best gating system finallyAccording to the design of heat transfer,design and calculate the large injection mold cooling system,determine the basic size and dispose the cooling circuit. Through using Mold flow/Cool analysis module,analyzes the cooling results. According to the result of the analysis,optimize the cool system,re-design the cool system,and get a reasonable cool system finally.According to the empirical formula, calculate the dimensioning of plastic injection mold part.In order to ensure that there is no elastic or plastic deformation occurred in the injection process, the finite element static analysis is done for preliminary design of the slide and die sets,and check the intensity and stiffness of cavity thickness, using ANSYS software.Using UG/Mold Wizard module optimizes the design and checking their parameters for basic parts of large-scale injection mold,achieves the virtual assembly of the injection mold finally,and provide a reasonable and effective design for large injection mold design.
