The Search And Development Based On Function Module For Injection Moulds

Mould quotation is an important economical condition to achieve a successful deal between the Mould&die corporations and its clients, is the key step by which corporations to gain potential clients or orders and hold the old clients, and also it is a comprehensive reflection of all aspects of the mould industry including management, equipment, capability of manufactures, etc. Mould quotation is really critical for the cost of mould because it will decide whether can a mould corporation survive in the competition.

With this method, the dissertation divide the mould cost into 7 categories: Design engineering module, Core&cavity module, the Moldbase module, the Lifter module, the Slider module, the Hot runner module, the Mold Assemble module. And because the quotation needs enough experience, the dissertation bring forward CBR(Case-Based Reasoning) method to take mould-finished cost accounting as an important reference data for injection mold quotation, by which way the quotation was simplified.Finally, applying the above theories, an injection mold system, which is based on function module, has been developed on VB by adopting ACCESS as the database. As application verification, the paper gives a brief introduction by a quotation of LCD REAR COVER.
