Description

Technical Field

[0001] The invention relates to the technical field of mold turning equipment, and in particular to a mold turning mechanism and a conveying equipment with a mold turning function. Background Art

[0002] As the demand for large prefabricated parts in the construction, engineering and manufacturing industries increases, the relevant production processes and equipment are also constantly being updated and optimized. In the production process of large prefabricated parts, mold flipping and disassembly are crucial links. Traditional molds are usually bulky and large in size, and the flipping and disassembly process requires precise control and careful operation. For this reason, mold flipping and disassembly often rely on specialized equipment and technology to ensure that the prefabricated parts can be removed from the mold safely and quickly, and to avoid deformation or damage during the disassembly process.

[0003] At present, many workshops generally use gantry cranes and other lifting equipment to perform operations when turning over and disassembling large prefabricated molds. The mold is extracted through the hook on one side of the crane. It is usually necessary to turn the mold over to the ground and then take out the product. During this process, workers need to bind tools such as slings and rings before performing lifting operations. Although this method can complete the turning and disassembly of the mold, due to the cumbersome operation process and the need for more manual cooperation, it is not only inefficient, but also because the lifting process involves the handling of a large number of heavy objects, there are certain safety hazards, such as loose slings and equipment failures.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0038] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0039] like Figures 1 to 7 In a first aspect of the present invention, a mold turning mechanism is provided.

[0040] The mold flipping mechanism includes: two relatively arranged mounting plates 1, a base 2, a first driving mechanism 3 and a clamping assembly 4; the two mounting plates 1 are connected to each other through a connecting shaft 11, and the two mounting plates 1 are respectively rotatably connected to the base 2, and the first driving mechanism 3 is used to drive the mounting plates 1 to rotate on the base 2.

[0041] The clamping assembly 4 is used to clamp the mold. After the clamping assembly 4 clamps the mold, the first driving mechanism 3 is started, and the first driving mechanism 3 drives the mounting plate 1 to rotate on the base 2. The rotation of the mounting plate 1 directly drives the clamping assembly 4 to rotate, and the clamping assembly 4 drives the mold to rotate, thereby realizing the flipping of the mold. After the mold flipping is completed, the clamping assembly 4 is controlled to cancel the clamping of the mold, and then the mold can be safely removed to complete the mold flipping operation.

[0042] Specifically, the first driving mechanism 3 includes a first motor 31, a first driving sprocket 32, a first chain 33 and a first driven sprocket 34; the first motor 31 is fixedly mounted on the base 2, the first driving sprocket 32 ​​is connected to the output end of the first motor 31, the first driven sprocket 34 is connected to the mounting plate 1, and the first chain 33 is meshedly connected between the first driving sprocket 32 ​​and the first driven sprocket 34. When the first motor 31 is started, the output end of the first motor 31 drives the first driving sprocket 32 ​​to rotate, the first driving sprocket 32 ​​drives the first driven sprocket 34 to rotate through the first chain 33, and the first driven sprocket 34 drives the mounting plate 1 to rotate, thereby driving the mounting plate 1.

[0043] The clamping assembly 4 includes a hydraulic telescopic rod 41 and two clamping parts 42. The rotating parts of the two clamping parts 42 are rotatably connected to the surfaces corresponding to the two mounting plates 1, and the number of the hydraulic telescopic rods 41 is four. One end of the hydraulic telescopic rod 41 is rotatably connected to the mounting plate 1, and the mounting plate 1 is provided with an arc groove 12. The swinging parts of the two clamping parts 42 pass through the arc groove 12 and are connected to the other end of the hydraulic telescopic rod 41. A clamping space for clamping the mold is formed between the two clamping parts 42.

[0044] During use, the mold is placed between the two clamping parts 42, and the hydraulic telescopic rod 41 is activated to retract. The output end of the hydraulic telescopic rod 41 drives the swinging part of the clamping part 42 to move along the arc groove 12, and the rotating part of the clamping part 42 rotates accordingly, causing the clamping space between the two clamping parts 42 to gradually shrink until the mold is clamped. At the same time, the first driven sprocket 34 drives the mounting plate 1 to rotate, so that the clamping part 42 on the lower side always remains in a horizontal state, ensuring that the mold is firmly clamped.

[0045] After the mold is firmly clamped, the first driven sprocket 34 continues to drive the mounting plate 1 to rotate. The rotation of the mounting plate 1 drives the clamping portion 42 to rotate, and the clamping portion 42 further drives the mold to flip 180 degrees, thereby completing the flipping operation of the mold.

[0046] Through the cooperation of the hydraulic telescopic rod 41 and the first driving mechanism 3, the mold can be flipped, reducing the cumbersome manual operation and safety hazards in the traditional method, thereby improving work efficiency and operational safety and reducing dependence on manual operation.

[0047] In this embodiment, the clamping part 42 includes two connecting plates 421, a first roller 422, a second roller 423 and a third roller 424. The first roller 422 and the second roller 423 respectively penetrate the two connecting plates 421, wherein the end of the first roller 422 is the rotating part of the clamping part 42 and is rotatably connected to the mounting plate 1. The end of the second roller 423 is the swinging part of the clamping part 42, and passes through the mounting plate 1 through the arc groove 12 and is connected to the other end of the hydraulic telescopic rod 41. The third roller 424 is located between the first roller 422 and the second roller 423, and is connected to the two connecting plates 421, so that the structure of the clamping part 42 is more stable.

[0048] During use, the hydraulic telescopic rod 41 is first controlled to be retracted. The retracting action of the hydraulic telescopic rod 41 causes the second roller 423 to slide along the arc groove 12 on the mounting plate 1, and the connecting plate 421 rotates with the movement of the second roller 423. Due to the existence of the arc groove 12, the rotation of the connecting plate 421 drives the rotating part of the clamping part 42 (i.e., the first roller 422) to rotate accordingly, thereby causing the distance between the clamping parts 42 to gradually decrease, and finally achieving the clamping action.

[0049] When the two clamping parts 42 clamp the mold, the first roller 422, the second roller 423 and the third roller 424 clamp the mold to ensure that the mold will not loosen or shift during the turning process.

[0050] Specifically, when the hydraulic telescopic rod 41 is retracted, it drives the second roller 423 to slide, ensuring that the clamping space between the clamping parts 42 can be stably reduced. During the whole process, the rotating part of the first roller 422 and the swinging part of the second roller 423 work together under precise control to ensure that the clamping force is evenly distributed and effectively avoid uneven force on the mold during the clamping process.

[0051] In this embodiment, two limit assemblies 5 are further included, and the two limit assemblies 5 are respectively connected to the two clamping parts 42. Each limit assembly 5 includes a first cylinder 51, a limit plate 52, a connecting part 53 and a connecting beam 54. The connecting beam 54 is fixedly installed between the two connecting plates 421, the first cylinder 51 is rotatably connected to the connecting beam 54, the output end of the first cylinder 51 is rotatably connected to the connecting part 53, the connecting part 53 is fixedly connected to the limit plate 52, and the limit plate 52 is rotatably installed between the two connecting plates 421.

[0052] The limiting plate 52 is provided with a curved portion 521, which is used to limit the mold to prevent displacement or instability of the mold during the clamping process. When the first cylinder 51 is started, the output end of the first cylinder 51 extends to push the connecting portion 53 to rotate, thereby driving the limiting plate 52 to rotate. The curved portion 521 of the limiting plate 52 enters the clamping space to limit the mold, ensuring that the position of the mold is stable during the clamping process, and preventing the mold from affecting the clamping effect due to displacement or uncontrolled shaking.

[0053] In this embodiment, if Figure 1 , Figure 5 and Figure 6 As shown, the second driving mechanism 6 and the transmission assembly 7 are also included. The transmission assembly 7 includes a rotating shaft 71, two first transmission sprockets 72, two third chains 73 and two second transmission sprockets 74. The rotating shaft 71 passes through the mounting plate 1 and is rotatably connected to the mounting plate 1. The second driving mechanism 6 is used to drive the rotating shaft 71 to rotate, the two first transmission sprockets 72 are fixedly connected to the rotating shaft 71, and the two second transmission sprockets 74 are respectively connected to the first rollers 422 of the two clamping parts 42. The third chain 73 connects the first transmission sprocket 72 and the second transmission sprocket 74, and transmits the driving force through the meshing connection.

[0054] The first roller 422, the second roller 423 and the third roller 424 are all rotatably connected to the connecting plate 421. The second driving mechanism 6 includes a second motor 61, a second driving sprocket 62, a second chain 63 and a second driven sprocket 64. The second motor 61 is connected to the base 2, the second driving sprocket 62 is installed at the output end of the second motor 61, the second driven sprocket 64 is connected to the rotating shaft 71, and the second chain 63 is meshed and connected between the second driving sprocket 62 and the second driven sprocket 64. When the second motor 61 is started, the output end of the second motor 61 drives the second driving sprocket 62 to rotate, the second driving sprocket 62 drives the second driven sprocket 64 to rotate through the second chain 63, and the second driven sprocket 64 drives the rotating shaft 71 to rotate, thereby realizing the driving of the rotating shaft 71.

[0055] When the second driving mechanism 6 drives the rotating shaft 71 to rotate, the rotating shaft 71 drives the two first transmission sprockets 72 to rotate, and the two first transmission sprockets 72 drive the second transmission sprocket 74 to rotate through the third chain 73, thereby driving the first roller 422 to rotate. In actual use, in the initial state, the mold is placed on the first roller 422 of the clamping part 42 located at the lower side. Subsequently, the second driving mechanism 6 is started, and the second driving mechanism 6 drives the rotating shaft 71 to rotate, and the rotating shaft 71 indirectly drives the first roller 422 to rotate through the first transmission sprocket 72 and the third chain 73, thereby conveying the mold into the clamping space.

[0056] Next, the mold is clamped by two clamping parts 42, and the mold flipping operation is started. When the mold is flipped to 180 degrees, the flipping work is completed. After that, the second driving mechanism 6 is started, and the mold is further transported out by the rotation of the first roller 422, completing the flipping and transportation process of the mold.

[0057] In this embodiment, the clamping assembly 4 further includes a connecting assembly 43, which includes a swing arm 431 and two connecting rods 432. The two connecting rods 432 are respectively connected to the two ends of the swing arm 431, and one end of the connecting rod 432 away from the swing arm 431 is respectively connected to the connecting plates 421 of the two clamping parts 42. The rotating shaft 71 is rotatably connected to the swing arm 431.

[0058] The setting of the swing arm 431 is used to provide certain support for the rotating shaft 71, thereby improving the stability of the rotating shaft 71. Furthermore, when the two clamping parts 42 rotate, the connecting plate 421 drives the swing arm 431 to move through the connecting rod 432, so that the swing arm 431 swings. The setting of the connecting assembly 43 effectively improves the synchronization of the movement between the two connecting plates 421, thereby improving the synchronization of the two clamping parts 42 during the clamping and rotation process, ensuring that the work of the clamping parts 42 is more coordinated and reducing deviation or asymmetry.

[0059] The design of the connecting assembly 43 can ensure the stability and accuracy of the clamping portion 42 during movement, further improving the reliability of the mold flipping operation and avoiding problems such as inaccurate mold position or loose clamping due to poor synchronization.

[0060] In this embodiment, two groups of supporting wheels 21 are rotatably mounted on the upper surface of the base 2, and the number of each group of supporting wheels 21 is two. Two mounting plates 1 are respectively mounted on the two groups of supporting wheels 21 and are rotatably connected with the base 2. Each group of supporting wheels 21 cooperates with the mounting plate 1 to provide rotation support, so that the mounting plate 1 can achieve stable rotation on the base 2.

[0061] Through this design, the setting of the supporting wheel 21 provides a stable rotating platform for the mounting plate 1, effectively reduces friction and wear, and ensures that the rotation operation of the mounting plate 1 is smoother and more stable. In addition, the number and distribution of the supporting wheels 21 are evenly distributed on the upper surface of the base 2, so that the entire system maintains a uniform load distribution during operation, further improving the stability and service life of the equipment.

[0062] like Figure 7As shown, in this embodiment, a locking assembly 8 is also included, and the locking assembly 8 includes a mounting seat 81, a second cylinder 82, a sleeve 83 and a locking member 84. The mounting seat 81 is fixedly connected to the base 2, the sleeve 83 is fixedly connected to the mounting seat 81, and the second cylinder 82 is fixedly connected to the base 2. The locking member 84 is slidably installed inside the sleeve 83, and the output end of the second cylinder 82 is connected to the locking member 84, which is used to drive the locking member 84 to extend out of the sleeve 83. A locking hole 13 for the locking member 84 to extend into is provided on the mounting plate 1.

[0063] In actual operation, the second cylinder 82 is started, and the output end of the second cylinder 82 drives the locking member 84 to move out of the sleeve 83. The end of the locking member 84 away from the second cylinder 82 is provided with a conical guide portion, which controls the locking member 84 to extend into the locking hole 13 on the mounting plate 1, thereby locking the mounting plate 1.

[0064] Furthermore, when the mold is placed on the first roller 422, the mounting plate 1 is locked by the locking assembly 8, and then the first roller 422 is driven to rotate to convey the mold so that the mold is located in the clamping space for easy clamping. The setting of the locking assembly 8 can effectively ensure the stability of the mounting plate 1 during the conveying of the mold.

[0065] like Figures 8 to 11 As shown, in the second aspect of the present invention, a conveying device with a mold flipping function is provided. The conveying device with a mold flipping function comprises: the above-mentioned mold flipping mechanism and at least one conveying mechanism 9, wherein the conveying mechanism 9 is connected to the mold flipping mechanism and is used to convey the mold to the conveying device with a mold flipping function.

[0066] The conveying device can realize the function of flipping the mold during the conveying process by cooperating with the mold flipping mechanism. The conveying mechanism 9 accurately delivers the mold to the position of the flipping mechanism, and through the action of the flipping mechanism, the mold is flipped to the required angle in a predetermined manner, ensuring that the mold can be flipped smoothly and accurately during the transportation process. This design can greatly improve the efficiency and safety of the mold conveying process, reduce manual operations, and avoid mold damage or personal injury.

[0067] In this embodiment, the conveying mechanism 9 includes a frame 91, a third driving mechanism 92 and a conveying roller 93; the conveying roller 93 is connected to the frame 91, and the third driving mechanism 92 is used to drive the conveying roller 93 to rotate, and the conveying roller 93 is flush with the clamping portion 42 located at the lower side.

[0068] When in use, the mold is placed on the conveying roller 93 , and then the third driving mechanism 92 is started. The third driving mechanism 92 drives the conveying roller 93 to rotate, and the conveying roller 93 conveys the mold to the clamping part 42 , and the clamping part 42 clamps the mold.

[0069] Furthermore, in order to improve convenience, a conveying mechanism 9 is provided on both sides of the mold turning mechanism, such as Figure 8 As shown, the mold is transported to the mold turning mechanism, and after passing through the mold turning mechanism, the mold is further transported.

[0070] In this embodiment, if Fig.11 As shown, each of the conveying roller shafts 93 is connected to two linkage sprockets 94 , and adjacent linkage sprockets 94 are connected via a linkage chain 95 .

[0071] Among them, the third driving mechanism 92 includes a third motor 921, a third driving sprocket 922 and a fourth chain 923. The fourth chain 923 is connected to the interlocking sprocket 94 on the conveying roller shaft 93. The output end of the third motor 921 drives the third driving sprocket 922 to rotate. The third driving sprocket 922 will drive the interlocking sprocket 94 to rotate through the fourth chain 923. The interlocking sprocket 94 drives the conveying roller shaft 93 to rotate, and at the same time drives other conveying roller shafts 93 to rotate through the interlocking chain 95.

[0072] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
