                 Abstract: Through a feasibility analysis of the physical elements of the partition cylinder, factors affecting
             the mold structure can be identified, allowing for the development of a feasible mold structure plan. After
             comparing and analyzing multiple feasible mold structure plans, the optimal optimized mold structure plan
             that meets the requirements of the injection molded parts can be determined before proceeding with
             mold design or modeling. The molding process of the partition cylinder is injection molding, as there are two
             placement forms of the partition cylinder in the injection mold. One is with the axis lying horizontally, and
             the other is with the axis vertical. By comparing the processing quality of the partition cylinder in these two
             placement forms of injection mold structures, it is found that Plan One cannot guarantee the coaxiality of the
             partition cylinder to within Φ0.03 mm, and the lower bottom of the outer cylindrical surface of the partition
             cylinder may produce ejector pin demolding marks, affecting the appearance. However, Plan Two does not
             have these drawbacks, making it the optimal optimized mold structure plan.
