| Popis: | 95 With the development of technique and science the industry products become more complex and precise. All trades and professions, service or industry, have to enhance the competitiveness for long-term management. From the view of mold industry, pursuing precision mold design is the important target for all mold companies. There are lots of things used in daily life or components applied in high technology utilizing mold technique in manufacturing process. Using mold technology can make repeated manufacturing processes more efficient. It is the reason that many companies invest lots of money into the research of mold techniques. It is clear to understand the importance of mold design. Plastic injection molding is the most popular molding process of industry and the mold cooling system is the most important design for injection molding. Generally the products manufactured using injection molding would occur some problems such as warpage or welding line which was related to the good or bad cooling process. The commercial software MOLDFLOW can efficiently predict the defect that would happen in the injection molding processes. It can reduce development time of product by using simulation instead of traditional trail-and-error process. But there are still lots of trials needed to accomplish the product design by turning the major factors affecting the results of simulation of commercial software. In order to improve the mold design process further without repeated trial-and-error turning procedure, this study combines particle swarm optimization algorithm with commercial software MOLDFLOW for optimization of cooling channel of plastic injection molding. The goal of this study is to develop the architecture of combination of own-developed particle swarm optimizer with injection mold simulator for finding the optimal configuration of cooling channel of injection mold in a limited time. Multi-objective optimization of cooling channel configuration for mold design was illustrated through studies of actual example of plastic injection molding. It can be found that good configuration of cooling channel can be achieved by applying architecture and computer programs developed in this thesis. |
