    • Golf club heads include at least one part having a side wall extending completely around the golf club head, wherein the side wall ends at an edge (a free end) that defines an open side of the part. An interior surface of this side wall has a draft angle of −1° or more as it extends to its edge. In some club heads, the interior surface of at least one club head part will be shaped so that the interior surface does not converge as the side wall of that part extends to its edge. For some club head parts, the planar cross sectional area defined inside the interior surface of the part will either stay the same or get larger as one moves to the part edge. By avoiding or limiting features of negative draft angles, converging interior surfaces, and/or smaller cross sectional areas on interior surfaces of a part, manufacturing and tooling may be simplified.
    • 高尔夫球杆头包括至少一部分,其具有完全围绕高尔夫球棒头部延伸的侧壁,其中侧壁在限定部件的开口侧的边缘(自由端)处终止。 该侧壁的内表面延伸到其边缘时具有-1°或更大的拔模斜度。 在一些球杆头中,至少一个球杆头部分的内表面将被成形为使得当该部件的侧壁延伸到其边缘时内表面不会会聚。 对于一些球杆头部分,限定在部件的内表面内的平面横截面面积将随着朝向部件边缘移动而保持相同或变大。 通过避免或限制部件的内表面上的负牵引角,会聚内表面和/或较小横截面积的特征,可以简化制造和加工。
