【正文】 he design knowledge should be reused. As a performance knowledgebased design activity, product model evolvement and reuse technology has recently attracted a lot of research and industrial interest. Troxlor presented the management of product design knowledge. The knowledge acquirement, model, retrieve and publishment were studied. Pan researched on product innovative design technology based on knowledge and presented the knowledge model. Tan introduced the multiple ways to express the configuration knowledge in mass customization model. Waterson verified the ontological mitment in knowledgebased system. In modern product design methods, there must be some management and maintenance problems of product model evolvement and performance knowledge history. Otherwise, the old performance knowledge of pleted product should be updated and consummated because of the function improvement, the customer requirement change and so on. That is, the performance knowledge and design result should be improved and modified based on current product model to make it to be a new injection molding machine product which meets the new design requirements. Compared with the original product, the new injection molding machine must have similar structure and coordinate or enhanced functions concurrently. Performance knowledge are consummated and enriched during the evolvement process of injection molding machine’s product model ceaselessly. Now, there are formidable challenges among the manufacturing enterprises in the multioutlet market economy environment. To make injection machines meet the customers’ individual requirements, the research on product model evolvement technology bees more and more important. The dynamic evolvement of injection molding machine’s product model and the updating and improvement of performance knowledge demand the further research on injection molding machine’s product. model and performance knowledge reuse technology． 2. Product model dynamics and evolvement driven factors Product model dynamics of injection molding machines Every aspect of the process of injection molding machine configuration design determines that it is a dynamic process． Its dynamics mainly appear as the following aspects： (1) Component sets of injection molding machines are dynamic． With the evolvement of injection molding machine’s product model, some new ponents would be added into the sets， and some old ponents which were eliminated would be deleted from the sets to perfect or update the pleted products ． (2) Parts of injection molding machine’s ponents are dynamic. Some parts in the product model would remodel their materials, colors and such characters to improve the product model integral performance. (3) Product models of injection molding machine sale dynamic． The product models in some design environment would transform into other models because of design requirements changing． (4) Completed injection molding machines are dynamic. In the lifecycle of pletely designed products, one or two parts of the injection molding machines would be updated or maintained． (5) Customers’ individual requirements of injection molding machines are dynamic． The same customer or different customers’ requirements would be changed in different time or different environment.
