Study of injection molding process simulation and mold design of automotive back door panel

Numerical simulation of the injection molding process outer panel automotive plastic rear door and mold design is presented here. Computer aided three-dimensional interactive application (CATIA) employed to original steel structure, modal thermodynamic properties back are changed by changing different materials panel. In order efficiently panels, finite element analysis used verify whether designed parts meet mechanical requirements such as light weight, low fuel consumption, short production cycle, strong modeling design, high corrosion resistance good recovery, above main parameters have been evaluated, carried out evaluate. To simulate process, computer engineering (CAE) software ANSYS HyperWorks analyze selected material. After numerical analysis, suitable material selected, so that product could be satisfied well improved. Unigraphics NX (UG) convex concave for automobile’s Combined with characteristics mold, multi-scheme pouring cooling system out. By comparing effects gating systems on molding, best selected. The artificial fish swarm algorithm optimize combination automobile obtained.
