Low1 and . Lee2ABSTRACTTo provide an initial design of the mould assembly for customers prior to receiving the final product CAD data is a preliminary work of any final plastic injection mould design. Traditionally and even up till now, this initial design is always created using 2D CAD packages. The information used for the initial design is based on the technical discussion checklist, in which most mould makers have their own standards. This technical discussion checklist is also being used as a quotation. This paper presents a methodology of rapid realization of the initial design in 3D solid based on the technical discussion checklist, which takes the role of the overall standard template. Information are extracted from databases and coupled with the basic information from customer, these information are input into the technical discussion checklist. Rules and heuristics are also being used in the initial mould design. A case study is provided to illustrate the use of the standard template and to exhibit its real application of rapid realization of the initial design for plastic injection moulds.INTRODUCTIONThe most established method for producing plastic parts in large quantities is plastic injection moldings. This is a highly costeffective, precise and petent manufacturing method, which can be automated. However, costly tooling and machinery are needed in this manufacturing process. The design of a plastic injection mould is an integral part of plastic injection moldings as the quality of the final plastic part is greatly reliant on the injection mould. A plastic injection mould is a high precision tooling that is being used to mass produce plastic parts and is by itself an assembly of cavities, mould base and standard ponents etc. An example of an injection mould assembly is shown in Figure 1.Over the years, much research work using puteraided techniques had been done from studying the very specific areas of mould design to studying mould design as a whole integrated system. Knowledgebased systems such as IMOLD, ESMOLD, IKMOULD, etc were developed for injection mould design. Many mercial mould design software packages such as IMOLD, UG Mold Wizard, Mold Works, etc are also available today in the market for mould makers. However, the systems and software packages mentioned above did not consider the initial design prior to actual mould design. Figure 1: An injection mould assemblyThere is not much research being done on the initial design of plastic injection moulds except for Ye et al. (2000) who presented an algorithm for the initial design. The researchers first determine the parting line for the plastic part followed by the calculation of the number of cavities required. The cavity layout is created based on the input information of the layout pattern and the orientation of each cavity. The mould base is loaded automatically to acmodate the layout. The researchers also proposed to use their initial design as a guide tool for the quotation of the mould. However, the research that is being done may not be applicable for most plastic injection moldings industries. The calculation of the number of cavities required is mostly determined by the customers who provides the product CAD file and they seldom seek opinion from the mould makers, thus this step could be omitted to save time.
