The 3D models of gating system, ejection mechanisms and cooling system of the swtich shell for injection mold are designed by using Pro/ENGINEER software. MOLDFLOW is utilized for CAE analysis. Three schemes are obtained by changing the gate location during the injection molding process. After comparing the volume shrinkage during injection, shrink marks index, filling time and the injection pressure, the best scheme is obtained. According to the optimal scheme, the injection mold is designed. The results showed that simulation analysis method can not only improve the successful probability of mold trial, but also shorten the production development cycle of developing product.

The overall injection mold structure scheme was determined based on the processing analysis of a large LCD TV panel. Specific heating/cooling system and temperature control system aiming for better surface finish were designed. The runner system, which starts from a pin valve hot runner system and turn to cold runner and then to banana-like gates, was obtained. Lifters used for smooth ejection and pulling side cores were presented. The venting system and the material for the cavity plate were introduced. The assembly drawing was shown and the working process of the mold was described at last.

For the cooling system of plastic injection mold affects significantly the productivity and quality of the finial products, the cooling system design is of great importance. In this paper, considering the location, size, number of cooling channels and mold material properties, the optimization design of heterogeneous injection mold cooling system is discussed to achieve simultaneously fast and uniform cooling. A mathematical model is constructed in which the part temperature distribution uniformity and production efficiency are taken as the objective function for cooling system design of heterogeneous injection mold. For the reason of the non-linearity of design problem and the coupling of geometric with material variable, the design problem is divided into two sub-problems and the combining algorithm is used in such way that, the geometric optimization sub-problem is solved by Hooke-Jeeves method and the material optimization sub-problem is solved by particle swarm optimization (PSO) method. The effectiveness of the approach is illustrated by a design example of injection mold cooling system.
