Because the water tray 2 and the branch side module 1 are both arc-shaped, the water-cooling main body channel 3 adopts an arc-shaped structure, so that the casting can be rapidly cooled, the cooling efficiency is high, the production efficiency and the qualification rate of the casting are also improved, and the process parameter adjusting range of the production process of the arc-shaped water-cooling main body channel 3 is large, and the machine is convenient to adjust.

The annular inner wall of the side die forms a cavity wall matched with the outer wall surface of the hub, and the cavity wall of the side die, the cavity walls of the upper die and the lower die form a cavity for injection molding of the hub. As shown in fig. 1-2, the side form is formed by splicing four sub-side modules 1, the sub-side modules 1 are of arc structures with the same radian of inner and outer arc surfaces, the four arc sub-side modules 1 form an annular side form, the central angle corresponding to each sub-side module 1 is 90 degrees, the sub-side modules 1 are mutually independent, and the adjacent sub-side modules 1 are hinged by hinges and are convenient to disassemble and assemble.

As shown in fig. 1-3, water tray 2 sets up the inboard at minute side module 1 with minute side module 1 mutually independently, and water tray 2 is the arc structure that equals with minute side module central angle, and the central angle that corresponds is 90, because water cooling channel sets up on water tray 2, when water cooling channel is damaging, can change water tray 2 alone to practice thrift the later maintenance cost. The middle part of the outer cambered surface of the water tray 2 is provided with an arc-shaped groove to reduce the weight of the side mold. It is understood that, in other embodiments, the grooves may have other shapes, the number of the grooves may be multiple, and the number of the side dividing modules 1 and the water trays 2 and the corresponding central angles may be adjusted according to actual needs.

Further, each water-cooled body passage 3 provided in the water tray 2 corresponds to a central angle smaller than 90 ° and larger than 60 °. In order to avoid the over-small distance between the end point of the water-cooling main body channel 3 and the wall surfaces of the two ends of the water tray 2, the corresponding central angle of the water-cooling main body channel 3 is less than 90 degrees, so that the water leakage at the two ends is prevented; in order to cool the casting uniformly and reduce the cooling dead angle, the central angle corresponding to the water-cooling main body channel 3 should be larger than 60 degrees, such as 70 degrees, 75 degrees and the like. Preferably, the radians of the water-cooling main body channel 3, the side-parting module 1 and the water tray 2 are the same, so that the distances from the water-cooling main body channel 3 to the inner arc surfaces of the side molds are equal, and the casting can be uniformly cooled.
