Optimal Structure of PlayTrib by Molding Structure Design and Injection Condition

摘要

The present invention relates to the rib structure of the plate by the molded product structural design and injection conditions, in the case of a plate without a conventional rib structure, the deflection phenomenon is greatly generated by the external load, and the stress continues to increase, and also Mises (Von Mises) ) There was a problem that the product is destroyed due to the concentration of stress in the area to which the load is applied.;Therefore, the present invention is formed at regular intervals from the left and right sides and the upper and lower sides, the grid rib portion 42 having a height and thickness of a predetermined size; The grid rib portion has a different diameter from the center of the three or more and has a constant height and thickness consisting of a circular rib portion 44 formed of three circles, characterized in that the grid and circular structure of the application In consideration of the height, width and injection conditions, it is possible to improve the optimal resin flow characteristics and strength as well as to smoothly distribute the force and to significantly reduce the occurrence of product defects.
