[0032] Reference Figure 1-4The utility model provides a technical solution: a wheel hub casting mold locking device, including a workbench 1, an upper mold 2 and a lower mold 3, a locking mechanism including a locking rod 4, a moving groove 5, a wedge 6 and a connecting plate 7, the locking rod 4 is slidably sleeved inside the upper mold 2, a plurality of locking rods 4 are provided, the moving groove 5 is opened on one side of the locking rod 4, the wedge 6 is slidably installed inside the moving groove 5, the connecting plate 7 is fixedly installed on the top of the plurality of locking rods 4, a centering mechanism is arranged on the top of the workbench 1, a support frame 10 is fixedly installed on the top of the workbench 1, a hydraulic cylinder 11 is installed on the top of the support frame 10, the output end of the hydraulic cylinder 11 is fixedly connected to the top of the connecting plate 7, a first spring 12 is fixedly installed on the bottom of the connecting plate 7, the other end of the first spring 12 is fixedly connected to the top of the upper mold 2, a second spring 13 is fixedly installed on the side of the inner wall of the moving groove 5 away from the wedge 6, the other end of the second spring 13 is fixedly connected to the wedge 6 Then, a guide rod 14 is fixedly installed on one side of the wedge block 6 close to the inner wall of the movable groove 5, and the guide rod 14 penetrates the outer wall of the locking rod 4. By setting a locking mechanism, the hydraulic cylinder 11 is started to drive the connecting plate 7 to move downward, so that the wedge block 6 supports the upper mold 2 to move downward. Since the height of the top of the clamping block 18 and the locking block 19 is consistent with the height of the top of the lower mold 3, the wedge block 6 is squeezed after contacting the locking block 19 and gradually moves toward the inside of the movable groove 5. When the upper mold 2 contacts the lower mold 3, the wedge block 6 is completely retracted into the inside of the movable groove 5. At this time, the connecting plate 7 drives the locking rod 4 to continue to move downward, so that the first spring 12 squeezes the upper mold 2 until the height of the top of the wedge block 6 is lower than the height of the bottom of the locking block 19. The second spring 13 causes the wedge block 6 to pop out through the rebound force, and the upper mold 2 and the lower mold 3 are locked, thereby solving the problem that the existing equipment needs to manually operate the bolts to lock the upper mold 2 and the lower mold 3;

[0033] It is worth noting that the locking rod 4, the moving groove 5, the wedge block 6, the first spring 12, the second spring 13 and the guide rod 14 are all provided in plurality.

[0034] Reference Figure 1-4The centering mechanism includes a centering groove 8 and a centering block 9. The centering groove 8 is provided on the top of the workbench 1. The centering block 9 is slidably installed inside the centering groove 8. A turntable 15 is rotatably installed inside the workbench 1. A slide groove 16 is provided on the top of the turntable 15. The shape of the slide groove 16 is set to be arc-shaped. A limit block 17 is slidably installed inside the slide groove 16. The shape of the limit block 17 is set to be cylindrical. The top of the limit block 17 is fixedly connected to the bottom of the centering block 9. A clamping block 18 is fixedly installed on the top of the centering block 9. The shape of the clamping block 18 is set to be arc-shaped. A locking block 19 is fixedly installed on the side of the clamping block 18 away from the lower mold 3. A motor 20 is fixedly installed inside the workbench 1. The output end of the motor 20 is fixedly connected to the bottom of the turntable 15. By setting a centering mechanism, the lower mold 3 is placed on the workbench 1, and the motor 20 is started to drive the turntable 15 to rotate. The slide groove 16 squeezes the limit block 17. Through the cooperation of the centering groove 8, the centering block 9 drives the clamping block 18 and the locking block 19 to move to a position close to the central axis of the workbench 1, and the slide groove 16, the limit block 17, the centering groove 8, the centering block 9, the clamping block 18 and the locking block 19 can be correspondingly provided with multiple ones until the lower mold 3 is clamped, and an anti-slip pad can be installed on the clamping block 18 to improve the clamping effect. After casting is completed, the motor 20 is started in reverse, the lower mold 3 is released, and the lower mold 3 is replaced, thereby solving the problem in the prior art that the lower mold 3 needs to continue to cool after the upper mold 2 is cooled, affecting the production efficiency.

[0035] Specifically, the working process or working principle of the wheel hub casting mold locking device is as follows: when in use, the lower mold 3 is placed on the workbench 1, the motor 20 is started, the turntable 15 is driven to rotate, the slide groove 16 squeezes the limit block 17, and the centering block 9 drives the clamping block 18 and the locking block 19 to move to a position close to the central axis of the workbench 1 through the cooperation of the centering groove 8, and the slide groove 16, the limit block 17, the centering groove 8, the centering block 9, the clamping block 18 and the locking block 19 can be correspondingly provided with multiple ones until the lower mold 3 is clamped, and an anti-slip pad can be installed on the clamping block 18 to improve the clamping effect, and the hydraulic cylinder 11 is started to drive the connecting plate 7 to move downward, so that the wedge block 6 supports The upper mold 2 is supported and moved downward. Since the height of the top of the clamping block 18 and the locking block 19 is consistent with the height of the top of the lower mold 3, the wedge block 6 is squeezed after contacting the locking block 19 and gradually moves toward the inside of the movable groove 5. When the upper mold 2 contacts the lower mold 3, the wedge block 6 is completely retracted into the inside of the movable groove 5. At this time, the connecting plate 7 drives the locking rod 4 to continue to move downward, so that the first spring 12 squeezes the upper mold 2 until the height of the top of the wedge block 6 is lower than the height of the bottom of the locking block 19. The rebound force of the second spring 13 causes the wedge block 6 to pop out and lock the upper mold 2 and the lower mold 3. After casting is completed, the motor 20 is started in reverse to release the lower mold 3 and replace the lower mold 3.

[0036] It should be noted that the hydraulic cylinder 11 and the motor 20 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
