According to the theory of the injection mold to carry on the covered hull molding tool design, really include to determine the type to dividing-plane, to really settle the pour meatus position and forms, to really settle the form of taking off from the mold, to really settle the cool system; Analyze the nicety notes of the precision to the mold cavity and mould core of the nicety inject mould; constringed some problems of producing; the choice of the injection craft parameter etc. It is to assurance the injected progress smoothly. In the foundation of the hull CAD mold, To note the fluxion and to keep press of the inject mould, cooling etc. the process carries on the number emulation. The image keeps the view ground to imitate to mould the process physically, Predicting the molding tool design and mould the blemish of the influence of the condition upon the product and possible emergence; In the foundation of the CAD/ CAE research on the injection producing. Adopting the AutoCAD and Pro/ Engineer graphics software to carry on the shape design, the rack of the mold, the geometrical shape of the mould cavity, the extrusion system were designed; the static analysts of the main loaded parts of the mold are studied by the ANSYS, the FEA software. The solid molds for analysis were built by Pro/E software, and then change them old from .prt format to the .db format by ANSYS software .The molds were defined by the pre-processing part of the ANSYS, and were analyzed by the analysis part of the ANSYS. The results were deal by the post-processing part. T he analysis is based on the results of the paper CAE Optimization art.The main analysis contents and achievements are as follows:1 The die used fixed die half and loose core, point pouring glut was emplaced inside sphere shape core, the sphere and its subjacent circumference hookers were separated by forced demoulding-mode, when the die is sinking, components and pouring mouth were separated automatically, components can have a low defective index with and fit well with smooth surface, and didn't need to cut fash.2 For the analyses of the complicated solid mold of three dimensions, if it cannot influence the precision of the analyses, some unimportant curve surfaces of the mold should be wiped of. In his way can also greatly reduce the analysis time;3 In the beginning of the finite element analysis, coarse mesh should be made firstly. The fine grid size can not be taken until we find a good optimized mold. It can...
