초록
Recently, the mold industry has been developed to high-quality and high-productivity with various demands of the high-tech industry. Also, geometry parts of injection mold are complex and diverse optimum design through the injection molding analysis has become a matter of course. The mold industry is trying to revitalize the industry with demand technology development and manufacturing process improvement. However, products that have undercut is the need for a separate processing mechanism and structure of the mold is getting more complex, the cost is expensive. Therefore, improving the structure of the mold through a study on the forced ejecting for injection molding without undercut processing unit and to improve the productivity.
