On the one hand, the parting surface can be used as a limit surface when the mold is closed to ensure the thickness direction size of the steering knuckle product. On the other hand, the parting surface can balance the horizontal mold misalignment force and reduce the misalignment amount. A locking guide device 3 is installed between the upper mold 1 and the lower mold 2. The locking guide device 3 is located at the outer edge between the upper mold 1 and the lower mold 2 and is distributed in a rectangular shape. The locking guide device 3 includes an upper mold locking block 7 and a lower mold locking block 6. The upper side of the lower mold 2 is fixedly connected to the lower mold locking block 6.

A certain amount of movement and adjustment is performed through contact between the guide surfaces.

[0027] During the process of inserting the first guide post 15 into the first guide hole 9, the time when the first guide post 15 enters the first guide hole 9 takes precedence over the time when the upper mold locking block 7 enters the slot 8. During the process of inserting the second guide post 17 into the second guide hole 19, the time when the second guide post 17 enters the second guide hole 19 takes precedence over the time when the upper mold locking block 7 enters the slot 8, thereby guiding the mold, and through the cooperation of the guide post and the guide hole, the height of the locking block can be reduced.

[0028] There is a gap between the first guide post 15 and the left and right sides of the first guide hole 9 , and there is a gap between the second guide post 17 and the front and back sides of the second guide hole 19 , which facilitates the insertion of the first guide post 15 and the second guide post 17 .

[0029] The anti-loosening mechanism includes a cylinder 10, a sliding block 13, and an anti-loosening block 14. The upper outer wall of the lower mold locking block 6 is connected to the cylinder 10 by bolts, and the sliding block 13 is slidingly connected to the side of the slot 8. The telescopic end of the cylinder 10 is connected to the sliding block 13, and the side of the sliding block 13 close to the slot 8 is fixedly connected to the anti-loosening block 14. An anti-loosening groove 20 is opened on the side of the upper mold locking block 7, and the anti-loosening block 14 is inserted into the anti-loosening groove 20.

[0033] An upper die fixing plate 5 is provided on the upper side of the upper die 1 , and a lower die fixing plate 4 is provided on the lower side of the lower die 2 .

[0034] Working principle: During the mold closing process of the upper mold 1 and the lower mold 2, through the setting of the locking guide device 3, first, the first guide post 15 is inserted into the first guide hole 9, and the first guide surface 16 of the first guide post 15 contacts the first guide hole 9, so that the upper mold 1 can move forward and backward by a certain amount, optimize the position and improve the accuracy after mold closing. At the same time as the first guide post 15 is inserted into the first guide hole 9, the second guide post 17 is inserted into the second guide hole 19, so that the upper mold 1 can move left and right by a certain amount, which also improves the accuracy after mold closing, so that the upper mold 1 and the lower mold 2 can be accurately closed, the mold misalignment is reduced, and the quality of the steering knuckle is improved. In the process of optimizing the position, by splitting the movement into forward and backward movement and left and right movement adjustment methods, it is convenient to drive it for micro-adjustment, and the sliding block 13 is driven to move by the cylinder 10, so that the anti-loosening block 14 is inserted into the anti-loosening groove 20, which can effectively lock the mold to avoid loosening and improve the processing quality.
