[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Reference Figure 1 , Figure 4 This utility model provides an embodiment of a high-precision guiding mechanism for automotive precision molds, comprising a base 1. A threaded rod A6 is rotatably connected to the front end of the inner surface of the base 1, allowing the threaded rod A6 to rotate along the inner surface of the base 1. A horizontal plate 8 is threaded through and connected to the outer surface of the threaded rod A6, allowing the threaded rod A6 to drive the horizontal plate 8 to move laterally when rotating. A horizontal groove 9 is formed on the outer surface of the horizontal plate 8, allowing a guide post 4 to move laterally along the inner surface of the horizontal plate 8. The guide post 4 is slidably connected to the inner surface of the horizontal groove 9, ensuring that the guide post 4 always moves along a designated position under the constraint of the horizontal groove 9. The horizontal plate 8 is slidably connected to the bottom of the inner surface of the base 1, allowing the horizontal plate 8 to move laterally along the bottom of the inner surface of the base 1. A groove 5 is provided in the middle of the inner surface of the base 1. The outer surface of the guide post 4 is slidably connected to the inner surface of the groove 5. When the guide post 4 moves laterally with the horizontal plate 8, the groove 5 can change the direction of movement of the guide post 4, causing it to move along the direction of the groove 5, so as to realize the action of the guide post 4 moving closer or further away from each other. An adjustment component 15 is provided at the front end of the threaded rod A6, so that the operator can control the rotation of the threaded rod A6 and the connecting rod 7 by adjusting the component.

[0039] Reference Figure 2 , Figures 5-6A connecting rod 7 is rotatably connected to the inner surface of the threaded rod A6, allowing the connecting rod 7 to rotate along the inner surface of the threaded rod A6. A connecting piece 12 is threadedly connected to the rear end of the outer surface of the connecting rod 7, allowing the connecting rod 7 to drive the connecting piece 12 to move laterally when rotating. A traction block 13 is fixedly connected to the rear end of the outer surface of the connecting piece 12, allowing the traction block 13 to move together when the connecting piece 12 moves laterally. The outer surface of the traction block 13 is inserted into the inner surface of the threaded rod A6, so that when the traction block 13 is retracted into the threaded rod A6, it will contact the threaded rod B10. The adjusting component 15 includes an internal hexagonal hole A151 and an internal hexagonal hole B152. The internal hexagonal hole A151 is formed in the threaded rod A6. The outer surface of the 6 is designed so that when the internal hexagonal hole A151 is rotated using an external hexagonal wrench, the threaded rod A6 and the connecting rod 7 can rotate together. The internal hexagonal hole B152 is opened at the outer surface of the connecting rod 7 so that when the internal hexagonal hole B152 is rotated using an external hexagonal wrench, the connecting rod 7 can rotate independently. The inner surface of the base 1 is rotatably connected to the rear end of the inner surface of the base 1 so that the threaded rod B10 can rotate at the rear of the inner surface of the base 1. The outer surface of the threaded rod B10 is provided with a insertion groove 14. The outer surface of the traction block 13 is inserted into the inner surface of the insertion groove 14 so that when the traction block 13 is inserted into the insertion groove 14, the rotation of the threaded rod A6 can drive the threaded rod B10 to rotate together.

[0040] Reference Figures 3-5 The mold 2 is inserted into the top of the inner surface of the base 1, which provides support and positioning for the mold 2. The inner surface of the mold 2 is slidably connected to the outer surface of the guide post 4, so that the mold 2 can move along the direction of the guide post 4 during installation and movement, ensuring the accuracy of the mold installation position and improving the accuracy and reliability of the mold during operation. The front of the outer surface of the connecting rod 7 is fixedly connected to the limiting post 11, so that when the connecting rod 7 rotates, it can drive the limiting post 11 to rotate at the same time. The outer surface of the limiting post 11 is rotatably connected to the front end of the inner surface of the threaded rod A6, so that the limiting post 11 can ensure that the connecting rod 7 always rotates along the specified position inside the threaded rod A6. There are two sets of horizontal plates 8. The inner surface of one set of horizontal plates 8 is slidably connected to the outer surface of the threaded rod A6, and the inner surface of the other set of horizontal plates 8 is slidably connected to the outer surface of the threaded rod B10. Under the rotation of the threaded rod A6 and the threaded rod B10, the two sets of horizontal plates 8 can move closer or further away from each other, thereby driving the guide post 4 to adjust its position.

[0041] Reference Figure 4 , Figure 7The inclined groove 5 and the horizontal groove 9 are each provided with four sets. The four sets of inclined groove 5 and horizontal groove 9 cooperate with each other to realize the simultaneous position adjustment of the four guide pillars 4. The top of the outer surface of the mold 2 is fixedly connected to the injection tube 3, so that the injection liquid can be injected into the mold 2 through the injection tube 3. The bottom of the outer surface of the guide pillar 4 is fixedly connected to the T-shaped part 16, so that when the guide pillar 4 moves, it can drive the T-shaped part 16 to move together. The outer surface of the T-shaped part 16 is slidably connected to the bottom of the inner surface of the horizontal groove 9, so that the T-shaped part 16 can prevent the guide pillar 4 from falling out of the horizontal groove 9, and at the same time ensure the stability of the guide pillar 4 sliding in the horizontal groove 9, and ensure the reliability of the guide pillar 4 when working. The bottom of the inner surface of the base 1 is provided with a guide groove 18. The bottom of the outer surface of the horizontal plate 8 is fixedly connected to the guide block 17. The outer surface of the guide block 17 is slidably connected to the inner surface of the guide groove 18, further enhancing the stability of the horizontal plate 8 when moving in the base 1, preventing it from deviating, and ensuring the accuracy of the horizontal plate 8 movement.

[0042] Working principle: When molds 2 of different sizes need to be placed into the base 1, the internal hexagonal hole A151 is rotated by using an external hex wrench, which drives the threaded rod A6 to rotate. When the threaded rod A6 rotates, the traction block 13 on the connector 12 is inserted into the threaded rod B10, which in turn drives the threaded rod B10 to rotate. This causes the opposing threads on the two sets of threaded rods to move the two sets of horizontal plates 8 closer or further apart. When the horizontal plate 8 moves laterally, it also drives the two sets of guide pillars 4 inside the horizontal plate 8 to move laterally as well. When the guide pillars 4 move laterally, they slide and connect with the inner surface of the inclined groove 5 in the middle. Under the drive of the horizontal plate 8 and the guidance of the inclined groove 5, the guide pillars 4 move closer or further apart along the inside of the horizontal groove 9 on the horizontal plate 8. Because the two sets of threaded rods rotate simultaneously, the two sets of horizontal plates 8 can simultaneously drive the four sets of guide pillars 4 to move closer or further apart towards the center point of the base 1.

[0043] When only the positions of the two sets of guide posts 4 on one side need to be adjusted, a smaller external hex wrench is used to rotate the internal hexagonal hole B152, causing it to connect with the inner surface of the connector 12 via a thread. This causes the traction block 13 on the connector 12 to extend or retract into the threaded rod A6. When the traction block 13 retracts into the threaded rod A6, it disengages from the insertion slot 14 on the threaded rod B10, preventing both sets of threaded rods from rotating simultaneously when only the threaded rod A6 or the threaded rod B10 is rotated. This allows for position adjustment of only the two sets of guide posts 4 on one side.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
