碩士 === 中原大學 === 機械工程學系 === 87 === The process of injection molding is to inject the melted plastic materials into the cavity, form the mold through packing, cooling processes, and opens the mold. It applies on versatile merchandises and becomes the most utilized technique because of its simple process, mass-production ability, and low cost. The most recent orientation of the plastic products are designed toward the purpose of light-weighted、thin、small、and beautiful configuration. In order to achieve this purpose, the faster the injection velocity, the more sensitive the machine varies. As a result, a precise control on injection parameter and processes monitoring become more important to the quality of the products. Under such requirements, an ordinary injection machine and processes control could not offer a real-time and dynamic monitoring to make all of the entire injection process to be understood. The purpose of this study is to provide a control modulus to understand the entire injecting process, and monitor the whole process by extra pressure and VCDT sensors. These sensors monitor can transfer the data dynamically and transforms the data graphically on the computer. This control modulus can assist the users to understand to features of the injection-molding machine, check the accuracy of set parameters, and monitor the variable conditions of the cavity. The advantage of this modulus can provide an experimental precise data which can compares with the simulation result from Computer Aided Engineering (CAE) software.
