Detailed Description
In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined below to clearly and completely describe the technical solution of the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments, which can be obtained by a person skilled in the art without any inventive work based on the described embodiments of the present invention, belong to the protection scope of the present invention.
As shown in fig. 2-5, the inner mold core cooling structure of the rotor die-casting mold comprises an annular core body 1 with a hollow inner part and a disc body 2 integrally formed with the annular core body, wherein the disc body is arranged at one end of the annular core body, and the outer diameter of the disc body is larger than that of the annular core body; a plurality of groups of runners are arranged in the wall of the annular core body and distributed along the periphery of the annular core body, each group of runners is formed into a V shape by the intersection of two flow holes 8, and the plurality of groups of runners are sequentially communicated to form a coherent W-shaped cooling channel 5 with an inlet 3 and an outlet 4; an inlet channel 6 and an outlet channel 7 are arranged on the disk body along the radial direction of the disk body, the inlet channel is communicated with an inlet of the cooling channel, and the outlet channel is communicated with an outlet of the cooling channel. And after cooling, the cooling medium is discharged from the outlet of the cooling channel and flows back to the discharge channel to be discharged.
