The initial design isposed of decisions made at the early stage of themould design, such as the type of mould configuration,the number of cavities, the type of runner, the type of gate and the type of mould base. The detailed design isposed of the insert (core/cavity) design, the ejectionsystem design, the cooling and venting ponent design,the assembly analysis and the final drafting. To develop a good CAIMDS, an analysis of ‘whatthey have’ and ‘what they want’ needs to be they have. The customer’s requirements for the product. Thisincludes the detailed geometry anddimension requirementsof the product. An existing mould design library. This library coversthe standard or previously designedponents andassemblies of the mould design, for example, themould base (the fixed half and the moving half) andthe pocket (the fixed half and the moving half). An expert knowledge in injection mould design. Expertknowledge of both initial and detailed designs forthe injection mould is obtained mainly from experiencedmould designers. Such knowledge includesmaterial selection, shrinkage suggestion, cavity layoutsuggestion and others. What they want: An intelligent and interactive mould design design is often posed of a series ofdesign procedures. These procedures usually requirecertain mould parts to be created and existing mouldparts to be assembled. Such a mould design environmentneed not be fully automatic, especially forplicated products with many undercuts. Anintelligent and interactive environment will be a goodchoice to integrate some useful automation algorithms,heuristic knowledge and onlineinteraction by the experienced mould designer. Standard/previous designed ponents/assemblies(productindependent parts) management. Apart from the core and cavity, an injection mould hasmany other parts that are similar in structure and geometrical shape that can be used in other injectionmould designs. These parts are independent of the plastic mould products. They are standardponents that can be reused in different mould designs and mould sets. Useful tools (including solid design and analysiscalculation) in the core and the cavity (productdependentparts) design. Geometrical shapes and thesizes of the core and cavity system are determineddirectly by the mould product. All ponents insuch a system are product dependent. Also, theseparts are the critical ponents in the mould design Their geometrical requirements may be , some tools developed to design the core and thecavity based on partial automation and partialinter
