碩士 === 中原大學 === 機械工程研究所 === 98 === In the past, people use manual drawing to express their concepts on designing injector pins, lifters and inserts. So far, most companies use 2D systems to solve part of actual problems. The mainstream of developing CAD will be 3D molds in order to advance the accuracy, decrease the rate of altering design. Combining with engineering analysis and process, the development of integrated application can be accomplished. The study uses the browser built in the CAD software, Pro/ENGINEER, to plan and develop a rationalized guiding process of injector pins, angle pins and inserts with knowledge management. Formerly, engineers design specific positions, shapes and sizes of injector pins, angle pins and inserts based on their experience. To some new staffs who are lack of experiences, errors may occur easily without any standard design process. This may cost more time and money in order to alter these important devices in producing molds and performing trials. Therefore, the study is to construct a rationalized guiding process in designing injector pins, angle pins and inserts centered with CAD software, Pro/ENGINEER. The process guides the users to clearly plan the proper sizes of the angle pins and inserts and device forming. In the part of injector pins, the process gives hints, helping the users to select proper diameters and bring it into the injector pin design. In designing injector pin, the devices of angle pin are finished. The users then build up the water path through the standard designing process. Then, the users can follow the rationalized planned value of injector pin design and finish the plan of different injector pins in different positions by steps. Finally, the users can use the guidance of automatic assembly in process to quickly assemble different forms of injector pins. By using the information saved in the database, the new staffs are provided with related design concepts and help the design process of injector pins to be modular, systematized and in process. In the guiding process, the standardization of injector pin design and support of the database can reduce unnecessary errors and differences in design and decrease errors in breaking mold and shorten developing time.
