The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0030] The following is combined Figures 1-4 This invention describes a mold for a sliding hole in an automotive door hinge.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, an automotive door hinge slotting mold includes a support platform 110, a positioning block 120, a positioning pin 130, a push rod 140, and a steel ball 150.

[0032] The support platform 110 has a drain hole 112 for supporting the door hinge 50. When the car door hinge is placed on the support platform 110, the pin hole 52 of the door hinge 50 needs to be axially aligned with the drain hole 112.

[0033] A positioning block 120 is disposed on the support platform 110 to restrict the movement of the door hinge 50 along the surface of the support platform 110 and to align the pin hole 52 of the door hinge 50 with the drain hole 112. The positioning block 120 restricts the position of the door hinge 50 so that the axis of the pin hole 52 is aligned with or nearly aligned with the axis of the drain hole 112. The door hinge 50 has a threaded hole 54 perpendicular to the pin hole 52. After the pin hole 52 of the door hinge 50 is drilled, burrs are usually generated at the intersection of the pin hole 52 and the threaded hole 54.

[0034] Positioning pins 130 are disposed on the support platform 110 to restrict the rotation of the door hinges 50 along the surface of the support platform 110. Optionally, at least two positioning pins 130 are provided, symmetrically distributed on the support platform 110, to restrict the rotation of the door hinges 50 of the left and right doors of the vehicle, respectively.

[0035] The push rod 140 is located above the drain hole 112, and its end diameter is smaller than the inner diameter of the pin hole 52. It is used to transmit and apply thrust. The end of the push rod 140 facing the drain hole 112 is smaller than the size of the pin hole 52, and its length is greater than the depth of the pin hole 52.

[0036] The outer diameter of the steel ball 150 is equal to the inner diameter of the shaft pin hole 52, which is used to be placed on the shaft pin hole 52 and pass through the shaft pin hole 52 under the pushing of the push rod 140. When the vehicle door hinge 50 is placed on the bearing table 110, the positioning block 120 and the positioning pin 130 respectively limit the position and rotation of the vehicle door hinge 50, so that the vehicle door hinge 50 remains stable and the shaft pin hole 52 is aligned with the end of the push rod 140. The steel ball 150 is placed at one end of the shaft pin hole 52 close to the push rod 140, and the push rod 140 exerts pressure on the steel ball to make the steel ball move downward along the shaft pin hole 52 and pass through the shaft pin hole 52 until it falls from the shaft pin hole 52 into the leakage hole 112 of the bearing table 110, thereby realizing the hole slipping of the shaft pin hole 52. The steel ball 150 that falls out of the leakage hole 112 can be reused. The end of the push rod 140 towards the leakage hole 112 has a spherical concave part for accommodating part of the steel ball 150 to limit the lateral movement of the push rod 140 when pushing the steel ball 150.

[0037] The automobile door hinge hole slipping mold of the embodiment realizes the position limitation and rotation limitation of the vehicle door hinge 50 through the positioning block 120 and the positioning pin 130 respectively, so that the shaft pin hole 52 is aligned with the push rod 140, and the push rod 140 pushes the steel ball 150 on the shaft pin hole 52 to move downward while keeping the vehicle door hinge 50 stable, thereby completing the hole slipping operation of the shaft pin hole 52. During the hole slipping operation, the same steel ball 150 or the same outer diameter steel ball is used, so that the hole diameter of the shaft pin hole 52 of the vehicle door hinge 50 after hole slipping is relatively consistent. During the pushing process along the shaft pin hole 52, the outer periphery of the steel ball 150 accumulates on the inner wall of the shaft pin hole 52, so that the inner wall of the shaft pin hole 52 is relatively smooth and no burr is generated. Compared with the reamer hole tapping process, the efficiency of the hole slipping of the shaft pin hole 52 by the push rod 140 pushing the steel ball 150 is higher.

[0038] In the embodiment, the automobile door hinge hole slipping mold further comprises a top die 160, which is located above the bearing table 110, and the end of the push rod 140 away from the leakage hole 112 is fixed on the top die 160. The top end of the top die 160 is connected to a driving device.

[0039] The top die 160 is provided with a guide column 162 extending towards the bearing table 110, and the bearing table 110 has a guide hole 114 opposite to the guide column 162. The outer diameter of the guide column 162 is smaller than the inner diameter of the guide hole 114.

[0040] In the embodiment, the automobile door hinge hole slipping mold further comprises a groove plate 170 and a die seat 180. The groove plate 170 is fixed on the bottom of the bearing table 110, and the sliding groove 172 is connected to the leakage hole 112 and used to receive the steel ball 150 falling from the leakage hole 112. The sliding groove 172 is a groove extending from the middle of the groove plate 170 to the edge and inclined downward. The die seat 180 is arranged on the side of the groove plate 170 away from the bearing table 110. Figure 3 , The groove plate 170 is fixed on the bottom of the bearing table 110, and the sliding groove 172 is connected to the leakage hole 112 and used to receive the steel ball 150 falling from the leakage hole 112. The sliding groove 172 is a groove extending from the middle of the groove plate 170 to the edge and inclined downward. The die seat 180 is arranged on the side of the groove plate 170 away from the bearing table 110.

[0041] In the present embodiment, the positioning block 120 has a notch 122, see Figure 4 , the notch 122 is used to accommodate one end of the door hinge 50 having the shaft pin hole 52, when the door hinge 50 abuts in the notch 122, the leakage hole 112 is opposite to the shaft pin hole 52. The notch 122 is a trapezoidal port expanding from the middle of the positioning plate to the edge.

[0042] The technical features of the above embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not contradict, they should be considered as the scope of the present disclosure.

[0043] The above embodiments only express several implementation manners of the present application, the description is relatively specific and detailed, but it should not be understood as the limitation of the scope of the present application. It should be pointed out that, for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
