Description

Technical Field

[0001] This utility model relates to the field of mold design and manufacturing technology, and in particular to a novel universal mold for automatic wheel rolling. Background Technology

[0002] The new type of universal oscillating rolling mold for automatic wheel production line consists of an upper mold core and a lower mold core that are inclined at a predetermined angle, as well as an upper fitting ring and a lower fitting ring that can be pressed and embedded into the lower end of the rim ring cavity of the lower mold core. This mold can reduce material costs and improve production efficiency. By matching fitting rings of different sizes, its application range can be expanded to adapt to different wheel rim widths.

[0003] The ejection structure of the existing new type of automatic wheel rolling universal mold mainly relies on the key component at the lower mold core. The lower mold core is precisely positioned by the positioning pin and is firmly installed on the lower mold base with bolts. The ejector screw hole set in the lower mold base can assist in ejecting the lower mold core, indirectly helping the wheel to be ejected. However, when facing large-sized or high-strength wheels, a single ejector screw is prone to ejection failure due to insufficient load.

[0004] Existing universal oscillating rolling molds for new automatic wheel lines lack effective auxiliary ejection structures. When faced with wheels of complex shapes or large sizes, a single ejector screw is insufficient to provide enough ejection power, causing the wheel to fail to detach smoothly from the mold, affecting production efficiency and product quality. Therefore, a new universal oscillating rolling mold for automatic wheel lines is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a new type of universal oscillating rolling mold for automatic wheel lines, which aims to improve the problem that existing technologies cannot perfectly eject wheels.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel universal mold for automatic wheel rolling line includes a lower body. A second hydraulic cylinder is fixedly connected inside the lower body. A moving plate is fixedly connected to the drive end of the second hydraulic cylinder. A linkage plate is slidably connected inside the lower body. A hook is fixedly connected inside the lower body. A spring is fixedly connected inside the linkage plate. A pin is fixedly connected to the other end of the spring. A wedge is fixedly connected inside the moving plate. Two push rods are fixedly connected inside the moving plate. A push rod is fixedly connected inside the moving plate. A support frame is fixedly connected to the outside of the lower body. A stamping assembly is provided on the top of the support frame.

[0008] As a further description of the above technical solution:

[0009] The stamping assembly includes a hydraulic cylinder, the drive end of which is fixedly connected to a support plate, and the top of the support plate is fixedly connected to a motor.

[0010] As a further description of the above technical solution:

[0011] A disk is fixedly connected to the drive end of the motor, a fixed column is fixedly connected to the outside of the disk, a linkage column is fixedly connected to the other end of the fixed column, a support rod is fixedly connected to the bottom of the support plate, a rotating column is rotatably connected to the outside of the support rod, a limiting ring is rotatably connected to the other end of the rotating column, a fixed plate is fixedly connected to the outside of the limiting ring, and an upper template is fixedly connected to the other end of the linkage column.

[0012] As a further description of the above technical solution:

[0013] The fixed plate is rotatably connected to a rotating rod, and the other end of the rotating rod is fixedly connected to a limiting ring two. The limiting ring two is rotatably connected to a rotating column two.

[0021] The wedge is slidably connected inside the linkage plate, and the outside of the wedge engages with the groove of the pin.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, after the wheel is formed, the second hydraulic cylinder pushes the moving plate to move upward. Because the wedge block inside the plate is stuck in the pin groove, it drives the linkage plate to move upward synchronously. When the moving plate drives the wedge block to move upward, the pin is squeezed by the top protrusion of the hook, the compressed spring stores energy, the protrusion of the hook causes the pin to move, the wedge block disengages from the lock, the second hydraulic cylinder pushes the moving plate, and the linkage plate drives the push rod to complete the first ejection. After the wedge block disengages, the moving plate continues to move upward to achieve the second ejection to better eject the wheel.

[0024] 2. In this utility model, the starting motor drives the disc to rotate, and its edge fixing column is connected to the linkage column, causing the linkage column to rotate eccentrically, which in turn drives the upper template to swing eccentrically. The first limiting ring outside the rotating column between the two support rods at the bottom of the support plate is fitted around the linkage column to limit it. The second limiting ring at one end of the rotating rod inside the fixing plate is fitted around the linkage column through the second internal rotating column, and together with the linkage column, it limits and adjusts the angle.

[0031] 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.

[0032] Reference Figure 1 and Figure 3 This utility model provides an embodiment of a novel universal mold for automatic wheel rolling, comprising a lower body 1. A hydraulic cylinder 27 is fixedly connected inside the lower body 1, acting as a power source to generate linear thrust. A movable plate 24 is fixedly connected to the drive end of the hydraulic cylinder 27, causing the movable plate 24 to move. A linkage plate 25 is slidably connected inside the lower body 1, allowing it to slide horizontally within a groove in the lower body 1. A hook 18 is fixedly connected inside the lower body 1, fixed to the inner wall of the lower body 1. The outer wall of the hook 18 is slidably connected to the inside of the linkage plate 25. A spring 21 is fixedly connected inside the linkage plate 25, providing elastic restoring force to push a pin 20 to remain in its initial position. The other end of the spring 21 is fixedly connected to a pin 20, which is slidably connected inside the linkage plate 25. Under the action of the spring 21, the pin 20 slides along a vertical channel in the linkage plate 25. The movable plate 24 is fixedly connected inside... A wedge 19 is attached and fixed to the movable plate 24, moving up and down with the movable plate 24. The wedge 19 is slidably connected inside the linkage plate 25, allowing it to move up and down within the linkage plate 25. The outside of the wedge 19 engages with the groove of the pin 20, and the inclined surface of the wedge 19 is engaged with the bottom of the pin 20. When the movable plate 24 moves the wedge 19 up and down, the protrusion of the hook 18 presses against the outer wall of the pin 20, forcing the pin 20 to slide and releasing the engagement with the wedge 19, thus achieving [the desired effect]. Mechanical unlocking is achieved by two ejector rods 23 fixedly connected inside the movable plate 24. The ejector rods 23 are fixed on the movable plate 24 and move up and down with the movable plate 24, driving the ejector rods 23 to push the side of the mold, assisting the demolding process and ensuring that the wheels smoothly leave the mold. The outer wall of the ejector rods 23 is slidably connected to the inside of the linkage plate 25. A push rod 22 is fixedly connected inside the movable plate 24 and moves up and down with the movable plate 24 to achieve secondary ejection, making the mold more perfectly demolded.

[0033] The lower body 1 is externally fixedly connected to a support frame 3, which serves as the external support structure for the mold. A stamping assembly is provided on the top of the support frame 3. The stamping assembly includes a hydraulic cylinder 4, which is externally fixedly connected to the top of the support frame 3. The hydraulic cylinder 4 serves as the power source for the stamping assembly and is fixedly located on the top of the support frame 3, generating a vertically downward thrust. A support plate 5 is fixedly connected to the drive end of the hydraulic cylinder 4, which is driven by the hydraulic cylinder 4 to move vertically downward. A motor 6 is fixedly connected to the top of the support plate 5, and the motor 6 is fixedly located on the support plate 5.

[0034] Reference Figure 2 and Figure 4 A disk 7 is fixedly connected to the drive end of motor 6. Disk 7 receives the rotational power of motor 6 and rotates synchronously. A fixed column 8 is fixedly connected to the outside of disk 7. The fixed column 8 is eccentrically installed on the edge of disk 7 and forms an eccentric circular motion when disk 7 rotates. A linkage column 12 is fixedly connected to the other end of fixed column 8. When disk 7 rotates, linkage column 12 swings eccentrically under the drive of fixed column 8. A support rod 9 is fixedly connected to the bottom of support plate 5. Support rod 9 is fixed to the bottom of support plate 5. A rotating column 10 is rotatably connected to the outside of support rod 9. When linkage column 12 swings, rotating column 10 restricts the movement trajectory of linkage column 12 through its own rotation and swing, so that its swing angle and range meet the requirements of the rolling process. The other end of the linkage column 12 is rotatably connected to a limiting ring 11. A fixing plate 13 is fixedly connected to the outside of the limiting ring 11. The other end of the linkage column 12 is fixedly connected to an upper template 2. The upper template 2 is a forming component that directly acts on the wheel blank. A rotating rod 14 is rotatably connected inside the fixing plate 13. One end of the rotating rod 14 is rotatably connected to the fixing plate 13. A limiting ring 16 is fixedly connected to the other end of the rotating rod 14. A rotating column 15 is rotatably connected inside the limiting ring 16. One end of the rotating column 15 is rotatably connected to the outer wall of the linkage column 12. The rotating column 15 can move synchronously with the linkage column 12. The limiting ring 11 is rotatably connected to the outside of the linkage column 12 to ensure that the limiting ring 11 can smoothly constrain the swing of the linkage column 12.

[0035] Working principle: Start motor 6, which drives disc 7 to rotate. A fixed column 8 is fixed to the edge of disc 7. One end of fixed column 8 is connected to linkage column 12, causing linkage column 12 to rotate eccentrically, thereby causing upper template 2 to swing eccentrically. Two support rods 9 are fixed to the bottom of support plate 5. Rotating column 10 rotates on the opposite side of the two support rods 9. Restriction ring 11 rotates outside of rotating column 10. Restriction ring 11 rotates outside of linkage column 12 and plays a restrictive role. Rotating rod 14 rotates inside fixed plate 13. Restriction ring 2 16 is fixed to one end of rotating rod 14. Rotating column 2 15 rotates inside restriction ring 2 16. Rotating column 2 15 rotates outside of linkage column 12 and together with linkage column 12 plays a restrictive role. When adjusted to a certain angle, hydraulic cylinder 4 is started to push support plate 5 down, thereby causing upper template 2 to press on top of lower body 1.

[0036] After the wheel is formed, hydraulic cylinder 17 is activated, which pushes the moving plate 24 upward. Because the wedge 19 inside the moving plate 24 is stuck in the groove of the pin 20, it drives the linkage plate 25 to move upward synchronously. When the moving plate 24 drives the wedge 19 upward, the pin 20 is squeezed by the protrusion on the top of the hook 18, which squeezes the spring 21. The spring 21 generates elastic potential energy, and the protrusion of the hook 18 squeezes the pin 20 to move, thereby causing the wedge 19 to disengage from the pin 20. Hydraulic cylinder 17 pushes the moving plate 24, which drives the linkage plate 25. The linkage plate 25 drives the push rod 23 to move upward, realizing the first ejection. Then the wedge 19 disengages from the pin 20, and the moving plate 24 continues to move upward, realizing the second ejection, thus ejecting the wheel better.

[0037] 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.
