With the continuous development of communication technology, the requirements on the die castings of 5G products are higher and higher, and particularly, the requirements on the quality of cooling fins are higher and higher. The number of the radiating fins is also more and more dense, and the distance between the radiating fins is smaller and smaller, so that the conventional integral die core has certain difficulty in electric discharge machining and polishing due to the characteristics of the radiating fins, and any link has problems, which can lead to a series of subsequent problems. As the shape of the die is not easy to change once being determined, the insert assembly structure is adopted to reduce the processing difficulty, and the flat ejector pin is required to be adopted for ejection, so that the strength of the insert can be conveniently increased, and the ventilation effect of the die casting is improved.

However, the existing flat ejector pins are arranged at the positions of the riding lines of two panels, because the matching requirement of flat ejector pin holes is very high, all panels are required to be assembled and then subjected to wire cutting processing to ensure the precision, and because the number of panels forming the panel group is usually 26-32 (even more), accumulated errors can be generated, and the actual wire cutting holes are not formed on the riding lines of the panels. Because the insert itself is thin, damage cannot be avoided during mass production, and spare parts need to be made for replacement. The position of the ejector pin hole actually processed generates fine deviation and is not in the theoretical position, so that the ejector pin hole of the new insert and the ejector pin hole of the original insert are misplaced, the size is bigger or smaller, the ejector pin hole cannot be matched with the actual size of the ejector pin, ejection cannot be normally performed, and in addition, the original insert is damaged and deformed to different degrees in the use process, and the position deviation is easy to generate when the new insert is matched with the original insert.
