| Popis: | 101 This study explores the stress distribution of a medical disposal container product and the associated plastic injection mold during fabricating with different configuration ratio of cooling channel and different mold material. A detailed mold flow analysis in conjunction with structure analysis in the mold design process not only can determine whether the designed structural stiffness of mold is sufficient but also reduce the times of mold testing and the costs of mold modification, which improve the production efficiency dramatically. In the medical disposal container, the risk of sharps injury can also be reduced by the strengthened product stiffness. This study especially focuses on the needle-remover mechanism of medical disposal container in the objective to enhance its strength. By taking the ratio of cooling channel as variable factor, 1:3:5, 1:2.5:5 and 1:2:5, a mold flow analysis was first carried to simulate the temperature distribution on the mold. A structure analysis was then introduced to study the stress generated during the molding process. Each analysis is investigated after 20 molding process. Analysis results indicated that lower product stress could be obtained while the ratio of cooling channel configuration was 1:2:5, and the mold core insert material was beryllium copper. However, with the same ratio channel configurations and the material of core insert was AISI-P20 steel, the stress value can be similar to that of beryllium copper material. In addition, the analysis results also show that the total warpage on the bottom of the container in the vertical direction of the core insert with the AISI-P20 steel material is similar to that of beryllium copper.
