[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figure 1 , Figure 2 , Figure 3 As shown, the positioning mechanism in the automobile mold includes an upper mold 1, a lower mold 2 and a positioning bolt 3. The lower mold 2 is provided with an inclined groove 4 for the positioning bolt 3 to pass through. A sliding block 5 that can move laterally is provided at the upper end of the groove 4. The positioning bolt 3 passes through the sliding block 5. When the positioning bolt 3 moves up and down, the sliding block 5 is driven to move laterally at the same time. A notch 6 is provided on the sliding block 5. A pair of clips 7 for limiting the positioning bolt 3 are correspondingly provided on the inner wall of the notch 6. An elastic element that can be elastically reset is provided inside the clip 7.

[0016] The lower mold 2 is also provided with a sliding block 8, a slot 9 is opened on the sliding block 8, and a fastener 10 is provided on the inner wall of the slot 9. A positioning column 11 for matching the slot 9 is provided at the lower end of the upper mold 1. The positioning column 11 drives the sliding block 8 to move, and a stepped structure with an inclination is provided on one side of the fastener 10.

[0017] When the upper mold 1 is closed, the stepped structure is pushed to move the second clip 10 inward and limit the positioning column 11. The upper mold 1 is provided with a mounting hole 12 for mounting and driving the positioning bolt 3 to move up and down. The positioning bolt 3 passes through the groove 4 along the slope of the groove 4.

[0018] When the mold is opened, the upper mold 1 pulls up the positioning bolt 3 and the positioning column 11. Since the groove 4 has an inclination and the positioning bolt 3 is limited by the buckle 1 7, when the positioning bolt 3 is upward, it will abut against the buckle 1 7, and at the same time drive the sliding block 1 5 to slide outward, and the positioning column 11 will be driven upward by the upper mold 1 to break away from the limit of the buckle 2 10;

[0019] When closing the mold, the upper mold 1 inserts the positioning column 11 into the slot 9, and the positioning column 11 pushes the fastener 2 10 to both sides. The positioning bolt 3 moves downward, and when it contacts the fastener 1 7, it pushes the fastener 1 7 to both sides. When the positioning bolt 3 enters the groove 4, the fastener 1 7 is restored to its original state due to the elastic reset of the elastic element. When the positioning column 11 enters the slot 9, it pushes the fastener 2 10. Since the fastener 2 10 has an inclined stepped structure on one side, the fastener 2 10 will be squeezed inward during the mold closing process and lock the positioning column 11. During the mold closing process, the positioning bolt 3 squeezes the sliding block 1 5 through the slope of the groove 4 to make it slide inward.

[0020] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0021] Although the terms such as upper die 1, lower die 2, positioning bolt 3, channel 4, sliding block 1 5, notch 6, fastener 1 7, sliding block 2 8, slot 9, fastener 2 10, positioning column 11, and mounting hole 12 are frequently used in this article, the possibility of using other terms is not excluded. The use of these terms is only for the purpose of more conveniently describing and explaining the essence of the utility model; interpreting them as any additional limitation is contrary to the spirit of the utility model.
