Description

Technical Field

[0001] The utility model relates to the field of radiator mold structures, in particular to a novel blade insert structure. Background Art

[0002] With the changes in communication technology and the full commercialization of 5G communication, its communication base stations have increasingly higher requirements for the heat dissipation capacity of the radiator shell. The current practice is to increase the height of the heat dissipation teeth on the radiator shell. Therefore, the requirements for the manufacturing of die-casting molds are higher. First, how to solve the problem of processing and manufacturing the cavity of the high-tooth blade mold, and second, how to ensure the internal and external quality requirements of the product molding by the designed and manufactured mold. For the casting of high-tooth radiators, due to the difficulty in processing the blade cavity, the mold adopts an insert structure to form the cavity. The conventional insert structure is made into a single-sided edge processing, polishing, and inspection, which can reduce the cost of replacing spare parts. However, some blade cavities have multiple cylindrical structures. If they are made into single-piece inserts, weak points will appear and they are prone to breakage. If they are made into thicker inserts, deep cavities need to be processed. However, such deep cavities can only be processed by discharge machining, which not only takes a long time to process, but also requires a long time to polish, which increases the processing difficulty and processing cost. It also affects the surface quality of the product and is prone to sticking, tearing, and meat falling. Summary of the Invention

The first blade forming cavity 7 is located at the upper right side of the first single-sided insert. The front and rear sides of the first intermediate insert 2 have symmetrically arranged semi-cylindrical conical forming cavities 8, which, together with the semi-cylindrical conical forming cavities 8 on the other blade insert structures, form a complete cylindrical conical forming cavity. The structure of the second intermediate insert 4 is identical to that of the first intermediate insert 2. The second composite insert 3 comprises three stacked second single-sided inserts. A second blade-forming cavity 9 is located between any two adjacent second single-sided inserts, for forming intermediate heat dissipation blades. The second blade-forming cavity 9 is located at the top of the second single-sided inserts. The third composite insert 5 comprises three stacked third single-sided inserts. A third blade-forming cavity 10 is located between any two adjacent third single-sided inserts. The third blade-forming cavity 10 is located at the upper left side of the third single-sided inserts.
