DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] like Figures 1-14 As shown, the technical solution adopted by the present invention is as follows: a conveying device for processing aluminum alloy molds includes a conveying trolley 1 and a bearing assembly.

[0038] like Figure 1 As shown, the bottom of the transport trolley 1 is provided with rollers for transport. The upper end of the transport trolley 1 is open, and the left and right sides of the upper end of the transport trolley 1 are provided with slots to facilitate the movement of the load-bearing components through the slots to the outside of the transport trolley 1 for docking with the delivery platform or the receiving platform.

[0039] The load-bearing assembly includes a chain, a rectangular rod 17, a circular plate 23, a first frame 8, and a second frame 11. There are two chains, and the two chains are symmetrically arranged. One end of the chain is hinged to the first frame 8, and the other end of the chain is hinged to the second frame 11.

[0040] like Figure 2 、 Figure 6 、 Figure 7 As shown, a plurality of first driving rollers 9 are rotatably provided on the first frame 8, and a plurality of second driving rollers 12 are rotatably provided on the second frame 11. The first frame 8 and the first driving rollers 9 are moved away from each other, thereby unfolding the bearing assembly.

[0041] like Figure 2 、 Figure 4 、 Figure 5 As shown, each chain includes a plurality of hinged chain pieces 19. Between two chains, a rectangular rod 17 is rotatably connected between two symmetrical chain pieces 19. Specifically, as Figure 9 、 Figure 10 As shown, a connecting plate 18 is fixedly connected to each end of the rectangular rod 17. The connecting plate 18 and the rectangular rod 17 are arranged coaxially. The two connecting plates 18 correspond to two corresponding chain plates 19. One connecting plate 18 is rotatably disposed within a limiting ring 21, which is fixedly connected to the corresponding chain plate 19. The other connecting plate 18 is fixedly connected to the output shaft of the motor 20, which is fixedly mounted on the corresponding chain plate 19.

[0042] like Figure 8 、 Figure 11 As shown, multiple circular plates 23 are slidably mounted on each rectangular rod 17. Slide grooves 24 are defined within the circular plates 23, through which the circular plates 23 slide onto the rectangular rods 17. The sliding direction of the circular plates 23 is perpendicular to the axis of the rectangular rods 17. A fixed cylinder 25 is fixedly connected to the rectangular rods 17 within the slide grooves 24. A sliding rod 26 is sealed and slidably mounted within the fixed cylinder 25, and is fixedly connected to the circular plates 23. A spring 27 is mounted on the fixed cylinder 25, one end of which is fixedly connected to the rectangular rods 17, and the other end of which is fixedly connected to the circular plates 23.

[0043] In this embodiment, the plurality of motors 20 are located on the same side of the bearing assembly, and the plurality of limiting rings 21 are located on the other side of the bearing assembly.

[0044] A limiting member is provided between the load-bearing assembly and the conveying trolley 1 to limit the circular plate 23 . When the load-bearing assembly is horizontally unfolded, the limiting member prevents the circular plate 23 from sliding along the rectangular rod 17 and keeps the circular plate 23 coaxial with the rectangular rod 17 .

[0045] The limiting member includes a limiting plate 6 and a piston rod 22 .

[0046] like Figure 10 、 Figure 11 As shown, a fluid chamber is defined axially within rectangular rod 17. The end of the fluid chamber, remote from motor 20, extends into the corresponding chain link 19 and penetrates through the chain link 19 to communicate with the outside world. A fixed cylinder 25 is in communication with the fluid chamber. A piston rod 22 is sealingly slidably disposed within the fluid chamber. The fluid chamber is filled with hydraulic oil. Under the action of spring 27, rectangular rod 17 is positioned in the end of slideway 24, remote from slide rod 26.

[0047] like Figure 2 、 Figure 3 As shown, the limit plate 6 is fixedly connected to the inner wall of the conveyor trolley 1. A sloped surface 7 is defined on the underside of the limit plate 6. The lower end of the sloped surface 7 is tilted toward the inner wall of the conveyor trolley 1. When the load-bearing assembly is deployed, the piston rod 22 faces the limit plate 6. The length of the limit plate 6 is not less than the length of the chain.

[0048] Both sides of the first frame 8 are fixedly connected with a first slider 10, which is slidably arranged in a first horizontal guide groove 2 opened on the inner wall of the conveying trolley 1. The inner wall of the conveying trolley 1 is installed with a first electric-controlled slide rail for driving the first slider 10 to slide.

[0049] Both sides of the second frame 11 are fixedly connected with a fixed block 13, and the fixed block 13 is connected to a guide rod 14. A guide portion is provided on the inner wall of the conveying trolley 1, and the guide rod 14 is slidably arranged in the guide portion. The guide portion includes a third horizontal guide groove 4 and an inclined guide groove 5 provided on the inner wall of the conveying trolley 1. One end of the third horizontal guide groove 4 is connected to the inclined guide groove 5, and the inclined guide groove 5 is inclined downward away from the end of the third horizontal guide groove 4. The lower end of the inclined guide groove 5 is on the extension line of the limit plate 6. When the guide rod 14 is located at the lower end of the inclined guide groove 5, the first frame 8 and the second frame 11 are on the same horizontal plane.

[0050] The fixed block 13 is connected to a telescopic rod 15, which is mounted on a second slider 16. The second slider 16 is slidably arranged in a second horizontal guide groove 3 provided on the inner wall of the conveying trolley 1. A second electrically controlled slide rail is mounted on the inner wall of the conveying trolley 1 to drive the second slider 16 to move horizontally.

[0051] The first horizontal guide groove 2 , the second horizontal guide groove 3 and the third horizontal guide groove 4 are arranged in parallel, and the second horizontal guide groove 3 is located above the first horizontal guide groove 2 .

[0052] Working principle:

[0053] Initially, the first frame 8 and the second frame 11 are both in the transport trolley 1, and the guide rod 14 is located in the third horizontal guide groove 4. Figure 11 As shown, under the action of the spring 27, the rectangular rod 17 is at the lower end of the slide groove 24 in the circular plate 23. At this time, the circular plate 23 and the rectangular rod 17 are coaxial. Figure 10 As shown, the end of the piston rod 22 is flush with the end surface of the chain plate 19.

[0054] When in use, move the transport trolley 1 to one side of the delivery platform. Start the first electric control slide and the second electric control slide, as shown in FIG. Figure 2 In the direction shown, the first electric-controlled slide rail drives the first frame 8 to move to the left along the first horizontal guide groove 2, and the second electric-controlled slide rail drives the second frame 11 to move to the right along the second horizontal guide groove 3. The first frame 8 and the second frame 11 move away from each other, the load-bearing assembly gradually unfolds, and the chain gradually unfolds and gradually moves toward a horizontal state.

[0055] When the guide rod 14 moves into the inclined guide groove 5 , the guide rod 14 slides along the inclined guide groove 5 , the second frame 11 moves rightward and downward at the same time, and the telescopic rod 15 extends.

[0056] Until the guide rod 14 is at the lower end of the inclined guide groove 5 and the first slider 10 is at the left end of the first horizontal guide groove 2. At this point, the load-bearing assembly is unfolded and horizontal, with the upper end surfaces of the first drive roller 9, the second drive roller 12, and the circular plate 23 on the same horizontal plane. The piston rod 22 is directly opposite the limit plate 6. Furthermore, both the first frame 8 and the second frame 11 extend outside the conveyor trolley 1, with the first frame 8 or the second frame 11 docked with the delivery platform. In this embodiment, it is assumed that the first frame 8 is docked with the delivery platform.

[0057] Next, the first drive roller 9 rotates, and the delivery platform transports mold 28 onto the first drive roller 9. The first drive roller 9 drives mold 28 toward circular plate 23, that is, toward the right. Simultaneously, the motor 20 is activated, rotating the rectangular rod 17, which in turn rotates the circular plate 23. As mold 28 moves onto circular plate 23, it continues to move toward the right, driven by the circular plate 23. This continues until mold 28 reaches the center of the support assembly, at which point the first drive roller 9 and motor 20 are turned off.

[0058] When the motor 20 is turned off, the rectangular rod 17 is positioned at the lower end of the chute 24 in the circular plate 23. That is to say, the number of revolutions of the rectangular rod 17 is an integer, and when the rectangular rod 17 stops rotating, the rectangular rod 17 is positioned at the lower end of the chute 24.

[0059] When the supporting assembly is in the horizontally expanded state and the mold 28 is on the circular plate 23, the mold 28 presses the circular plate 23, tending to move the circular plate 23 downward along the rectangular rod 17. However, due to the restriction of the piston rod 22 by the limiting plate 6, the piston rod 22 cannot move out of the liquid chamber, and the circular plate 23 cannot move downward, so that the circular plate 23 and the rectangular rod 17 remain coaxial. This ensures that the mold 28 can move smoothly on the circular plate 23.

[0060] Afterwards, the first electric control slide rail and the second electric control slide rail are started, as shown in FIG. Figure 2 In the direction shown, the first frame 8 moves rightward along the first horizontal guide groove 2, and the second frame 11 moves leftward along the second horizontal guide groove 3. After the pulling force of the first frame 8 and the second frame 11 is lost, the mold 28 gradually moves downward and the chain sags.

[0061] When the guide rod 14 slides along the inclined guide groove 5, the second frame 11 moves to the left and upward at the same time until the guide rod 14 moves into the third horizontal guide groove 4. Then the second frame 11 moves to the left along the third horizontal guide groove 4. At this time, the horizontal plane where the second frame 11 is located is above the horizontal plane where the first frame 8 is located.

[0062] As the first frame 8 moves to the right and the second frame 11 moves to the left, the bearing assembly between the first frame 8 and the second frame 11 gradually wraps the mold 28. Until the chain is tightened so that the first frame 8 cannot continue to move to the right and the second frame 11 cannot continue to move to the left, the first and second electric control slides are closed, and the second frame 11 is above the mold 28. Figure 13 shown.

[0063] As the chain deforms, when the chain link 19 is offset from the stop plate 6 and the stop plate 6 is no longer restrained, the circular plate 23 slides downward along the rectangular rod 17 under the pressure of the die 28, and the piston rod 22 extends out of the liquid chamber. After losing the restraint of the stop plate 6, the circular plate 23 squeezed by the die 28 moves along the corresponding rectangular rod 17 away from the die 28. The circular plate 23 not squeezed by the die 28 remains coaxial with the corresponding rectangular rod 17, as shown in FIG. Figure 14 That is to say, the plurality of circular plates 23 will form a groove matching the mold 28 under the extrusion of the mold 28, which plays a role in limiting and fixing the mold 28 and ensuring the stability of the mold 28 during transportation.

[0064] During the transportation of the conveying trolley 1, the first frame 8, the first driving roller 9, the second frame 11 and the second driving roller 12 are all located inside the conveying trolley 1. This prevents the first frame 8 and the first driving roller 9 from colliding with external objects during the transportation of the conveying trolley 1, thereby maintaining the stability of the transportation process.

[0065] When the transport trolley 1 moves to one side of the receiving platform, the first electric control slide rail and the second electric control slide rail are activated. Figure 2 In the direction shown, the first electrically controlled slide rail drives the first frame 8 to the left, while the second electrically controlled slide rail drives the second frame 11 to the right. The first frame 8 drives the left end of the chain to the left, while the second frame 11 drives the right end of the chain to the right, causing the chain to gradually unfold and move toward a horizontal state, and the mold 28 to gradually move upward.

[0066] During the process of the bearing assembly expanding to a horizontal state, when the piston rod 22 extending outside the liquid cavity contacts the inclined surface 7 on the lower side of the limit plate 6, the piston rod 22 moves into the liquid cavity under the extrusion of the limit plate 6, causing the circular plate 23 to move upward along the rectangular rod 17. When the piston rod 22 abuts against the limit plate 6, the piston rod 22 returns to the liquid cavity, and the circular plate 23 is coaxial with the rectangular rod 17.

[0067] When the guide rod 14 moves to the lower end of the inclined guide groove 5, the chain is in a horizontal state, the second frame 11 and the first frame 8 are on the same horizontal plane, and the first frame 8 and the second frame 11 both extend to the outside of the conveying trolley 1, and the upper end surfaces of the first drive roller 9, the second drive roller 12 and the circular plate 23 are on the same horizontal plane.

[0068] Assume that the second frame 11 is docked with the receiving platform at this time, start the second drive roller 12 and the motor 20, the motor 20 drives the rectangular rod 17 to rotate, the rectangular rod 17 drives the circular plate 23 to rotate, and the circular plate 23 transports the mold 28 to the second drive roller 12, and then the second drive roller 12 transports the mold 28 to the receiving platform.

[0069] Of course, if the first frame 8 is docked with the receiving platform, the first driving roller 9 and the motor 20 are started, so that the circular plate 23 drives the mold 28 to move toward the first driving roller 9, and then the first driving roller 9 transports the mold 28 to the receiving platform.

[0070] After being horizontally unfolded, the carrying component is easy to dock with the delivery platform or the receiving platform, and the setting of the first drive roller 9, the second drive roller 12 and the circular plate 23 facilitates the movement of the mold 28 on the carrying component, thereby realizing automatic loading and unloading of the mold 28.

[0071] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
