The distance between the intersection point and the end part of the outer side of the window is defined as L, the total length of the outer side of the window is L, L is more than or equal to 1/3L and less than or equal to 2/3L, and the intersection point of the extension line of the joint line and the outer side of the window is positioned in the middle area away from the outer side of the window, so that the parting line and the window can be well matched as far as possible, and the optimal cooling effect and the optimal forming effect on the window position and the non-window heat section area are achieved.
This solution is applicable to hubs of conventional design, i.e. hubs that have a window count of 5-19 and cannot be divided exactly by 4. The number of the wheel hub windows is 4-8, namely the number of the wheel hub windows is 5, 6 and 7, at the moment, under the limit that the second side die is larger than the first side die 1, the two symmetrical first side dies 1 can only cover two half windows, namely a complete window, at the moment, the maximum included angle and the minimum included angle of the adjacent joint lines are both arranged on the wheel hub with the number of the windows being 7, the included angle of the two adjacent joint lines is defined as a, the angle of the minimum included angle is 360 degrees/7 degrees approximately equal to 51.53 degrees, namely the angle of the joint line included angle of the two sides of the first side die 1, and the angle of the maximum included angle is (360 degrees/7) 3 degrees approximately equal to 154.29 degrees.
When the number of the windows of the hub is 8-20, compared with the number of the windows of 4-8, the number of the windows is increased by four, each of the first side module 1 and the second side module can cover one more window, and the maximum angle and the minimum angle at the moment are the same as the maximum angle included angle and the minimum angle of the interval of 4-8. Similarly, compared with the interval with the number of windows being 8-12, each first side die 1 and each second side die can cover two more windows, compared with the interval with the number of windows being 12-16, each first side die 1 and each second side die can cover three more windows, compared with the interval with the number of windows being 16-20, each first side die 1 and each second side die can cover four more windows, when the number of the windows is gradually increased, the included angle formed by the adjacent windows relative to the center of the hub is gradually reduced, the included angle formed by the two adjacent joint lines is selected to be 360 degrees/7-a-3, the width difference between the first side die 1 and the second side die can be ensured to be as minimum as possible, and the upper limit and the lower limit of the value range of the included angle between the adjacent parting lines cannot exceed the maximum included angle and the minimum included angle of the hub with the number of windows being 7.
The above description is intended to be illustrative of the preferred embodiment of the present invention and should not be taken as limiting the invention, but rather, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
