[0031] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection, a contact connection, or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0032] A mold hoisting device 1, such as Figures 1-10 As shown, the system includes: a hanger 10, a pair of boom assemblies 20, and a lifting assembly 30. Specifically, the hanger 10 is used for hoisting with lifting equipment and has a vertical mounting surface 11. The boom assembly 20 includes a first boom assembly 21 and a second boom assembly 22, with the middle portions of the first boom assembly 21 and the second boom assembly 22 hinged together. The middle portions of the first boom assembly 21 and / or the second boom assembly 22 are pivotally connected to the mounting surface 11, allowing the first boom assembly 21 and the second boom assembly 22 to rotate in planes parallel to the mounting surface 11. The lifting assembly 30 is used for fixing to lifting holes on the mold and is slidably connected to the boom assembly 20, allowing it to slide along the extension direction of the boom assembly 20. The vertical mounting surface 11 means that the plane containing the mounting surface 11 is perpendicular to the horizontal ground.

[0033] It should be understood that, typically, the various lifting holes on a mold are distributed on a virtual circle within a vertical plane. This facilitates the mold's natural rotation into an upright position for easy mold closing after lifting. In this embodiment, by rotating the first lifting arm assembly 21 and the second lifting arm assembly 22 within a vertical plane, the included angle between them can be adjusted. Furthermore, by sliding the lifting assembly 30 along the extension direction of the lifting arm assembly 20, the position of the lifting assembly 30 can be adjusted, i.e., the distance between the lifting assembly 30 and the pivot axis of the lifting arm assembly 20 can be adjusted. This configuration allows the lifting assembly 30 to be fitted and fixed with lifting holes at different positions on different molds, enabling the mold lifting device 1 to adapt to multiple molds, thereby reducing production costs and improving production efficiency. In other words, the lifting assembly 30 can be fitted with lifting holes at different positions on virtual circles of different diameters, thus expanding the applicability of the mold lifting device 1.

[0034] In some embodiments, such as Figures 3-4 Therefore, each boom assembly 20 includes a beam 23 and a sliding member 24. The beam 23 includes a pivot portion 231 and two track portions 232. The pivot portion 231 is pivotally connected to the mounting surface 11. The two track portions 232 are respectively connected to opposite sides of the pivot portion 231 and extend away from each other. At least one sliding member 24 is connected to each track portion 232. The sliding member 24 can slide along the extension direction of the track portion 232. The sliding member 24 is used to install the lifting assembly 30 so that the lifting assembly 30 slides along the extension direction of the track portion 232.

[0035] In at least one embodiment, such as Figures 1-4 As shown, the mounting surface 11 of the hanger 10 is provided with a base 12 protruding towards the boom assembly 20. The extension direction of the base 12 is perpendicular to the mounting surface 11. The pivot portion 231 has a through hole 2311, which is adapted to cooperate with the base 12 so that the beam 23 can rotate around the base 12. In other words, both the first boom assembly 21 and the second boom assembly 22 can be pivotally connected to the base 12 through the through hole 2311 of the pivot portion 231. This arrangement helps to make the beam 23 of the first boom assembly 21 and the beam 23 of the second boom assembly 22 have the same structure, thereby reducing the types of parts in the mold lifting device 1 and reducing the production cost of the mold lifting device 1.

[0036] Furthermore, two track sections 232 extend away from each other from opposite sides of the pivot section 231, and each track section 232 is provided with at least one sliding member 24, which can slide along the extension direction of the track section 232. It should be understood that there are at least four sliding members 24 on the mold lifting device 1, that is, at least four lifting components 30 can be installed on the mold lifting device 1 for fixing with the lifting holes on the mold, thereby meeting the lifting requirements of most molds. It is worth mentioning that the adjustable distance range between the sliding member 24 and the pivot axis of the beam 23 is the radius range of the virtual circle where the lifting hole of the mold is adapted to the mold on the mold lifting device 1.

[0037] In some embodiments, such as Figure 1 and Figure 2 As shown, the mold hoisting device 1 also includes a telescopic push rod assembly 40, which is connected between the mounting surface 11 and the beam 23, so as to drive the beam 23 to rotate in a plane parallel to the mounting surface 11.

[0038] It is understandable that if gear transmission is used to drive the beam 23 to rotate, the overall mass of the boom assembly 20 is large, requiring a large drive and a motor to be installed as a power source. Not only will the gears and motor occupy a large space, but custom gears may also be required, which will increase the cost of the mold hoisting device 1 and make the overall structure more complex.

[0039] In this embodiment, a push rod assembly 40 is used to drive the beam 23 to rotate. By designing the distance between the pivot axis of the push rod assembly 40 and the beam 23, the lever arm can be increased, thereby reducing the required driving force. Furthermore, the push rod assembly 40 has a small volume, which reduces the space occupied and makes the structure of the mold hoisting device 1 more compact, which is conducive to the miniaturization of the mold hoisting device 1.

[0040] It is worth mentioning that, during the mold installation process, the angle between the first boom assembly 21 and the second boom assembly 22 can be adjusted via the push rod assembly 40 so that the lifting components 30 on each boom assembly 20 correspond to the lifting holes of the mold. Furthermore, after the mold and the mold lifting device 1 are installed, the beams 23 of each boom assembly 20 and the lifting components 30 can be limited by the body structure of the mold, and the push rod assembly 40 can be de-energized and does not require self-locking. This simplifies the control of the mold lifting device 1, saves energy, reduces energy consumption during production, and lowers production costs.

[0041] Furthermore, a large number of push rod assemblies 40 are available on the market, which reduces the design and manufacturing difficulty of the mold lifting device 1, as well as the manufacturing cost of the mold lifting device 1. It is worth mentioning that the push rod assembly 40 includes, but is not limited to, hydraulic push rods and electric push rods, and this application does not make specific limitations in this regard.

[0042] In some embodiments, such as Figures 1-3 As shown, a guide groove 233 is provided on the beam 23. The extension direction of the guide groove 233 is parallel to the extension direction of the track part 232, thereby making the structure of the beam 23 more compact and reducing the overall size of the beam 23. Furthermore, one end of the push rod assembly 40 is fixedly installed on the mounting surface 11, thereby improving the connection strength between the push rod assembly 40 and the mounting surface 11, thus improving the reliability and safety of the mold hoisting device 1; the other end of the push rod assembly 40 is slidably connected to the guide groove 233, and the beam 23 can be driven to rotate in a plane parallel to the mounting surface 11 by the extension and retraction of the push rod assembly 40.

[0043] It should be understood that, with one end of the push rod assembly 40 fixed to the mounting surface 11, the range of motion of the push rod assembly 40 during the extension and retraction process is approximately a straight line. This arrangement reduces the area swept by the push rod assembly 40 during the extension and retraction process, thereby reducing the risk of interference between the push rod assembly 40 and other devices. Furthermore, it enables the structure of the mold hoisting device 1 to be more compact, which is beneficial for miniaturizing the mold hoisting device 1.

[0044] In other embodiments, one end of the push rod assembly 40 is pivotally connected to the mounting surface 11, and the other end of the push rod assembly 40 is pivotally connected to the beam 23, thereby driving the beam 23 to rotate in a plane parallel to the mounting surface 11 through the extension and retraction of the push rod assembly 40.

[0045] In some embodiments, such as Figure 3 and Figure 4 As shown, the mold hoisting device 1 also includes a first drive assembly 50, which includes a lead screw 51 and a slider 52. The lead screw 51 is installed on the beam 23, and the extension direction of the lead screw 51 is parallel to the extension direction of the beam 23. The slider 52 is threadedly connected to the lead screw 51 and can move along the lead screw 51. The slider 52 is fixedly connected to the sliding member 24 and can drive the sliding member 24 to slide along the track 232.

[0046] It should be understood that the first drive assembly 50 is positioned on the side of the track portion 232 of the beam 23, thereby making the structure between the first drive assembly 50 and the beam 23 more compact. Furthermore, the lead screw 51 transmission has high positioning accuracy, allowing for minor adjustments to the sliding member 24 to align the lifting assembly 30 on the sliding member 24 with the lifting hole of the mold. In addition, the lead screw 51 and the slider 52 have a self-locking function, which helps prevent the slider 52 from sliding under gravity when the motor stops working, thus keeping the slider 52 in its current position and improving the reliability and safety of the mold lifting device 1.

[0047] It is worth mentioning that there are a large number of lead screw and slider modules available on the market, which can reduce the design and manufacturing difficulty of the mold hoisting device 1, as well as reduce the manufacturing cost of the mold hoisting device 1.

[0048] In some embodiments, such as Figure 3 and Figure 4 As shown, the lead screw 51 includes a first rod portion 511 and a second rod portion 512. The first rod portion 511 is installed on one of the track portions 232 of the beam body 23, and the second rod portion 512 is installed on the other track portion 232 of the beam body 23. The slider 52 includes a first slider 521 and a second slider 522. The first slider 521 is threaded to the first rod portion 511 and fixedly connected to one of the sliding members 24 of the boom assembly 20. The second slider 522 is threaded to the second rod portion 512 and fixedly connected to the other sliding member 24 of the boom assembly 20. The first rod portion 511 and the second rod portion 512 rotate synchronously to drive the two sliding members 24 to slide towards or away from each other.

[0049] It should be understood that, typically, a mold has four lifting holes, arranged radially opposite to each other on a virtual circle in a vertical plane. In this embodiment, through the cooperation of the first rod 511 and the first slider 521, the cooperation of the second rod 512 and the second slider 522, and the synchronous rotation of the first rod 511 and the second rod 512, the two sliding members 24 on the boom assembly 20 can slide towards or away from each other, thereby enabling the two lifting assemblies 30 fixed on the two sliding members 24 to move towards or away from each other. This ensures that the distance between the two lifting assemblies 30 installed on the same boom assembly 20 and the pivot axis of the boom assembly 20 remains consistent. This arrangement facilitates the rapid adjustment of the two lifting assemblies 30 on the same boom assembly 20, allowing the two lifting assemblies 30 to be fitted one-to-one with the two radially opposite lifting holes on the mold, thereby improving the efficiency of mold replacement and installation.

[0050] It is worth mentioning that the first rod 511 and the second rod 512 can be integrated or separate; the first rod 511 and the second rod 512 can be driven by the same motor or by separate motors, and this application does not impose any specific restrictions on this.

[0051] In one specific embodiment, such as Figure 3 and Figure 4As shown, the first rod portion 511 and the second rod portion 512 are separately arranged. The first drive assembly 50 also includes a drive motor 53, which is disposed on the pivot portion 231 between the first rod portion 511 and the second rod portion 512. The output shaft of the drive motor 53 is connected to a driving bevel gear, and the first rod portion 511 and the second rod portion 512 are respectively provided with driven bevel gears. Through the cooperation of the driving bevel gears and the driven bevel gears, the first rod portion 511 and the second rod portion 512 can be driven to rotate synchronously. It should be understood that this arrangement makes the force on the drive motor 53 and the driving gear more balanced, which is beneficial to extending the service life of the drive motor 53 and the driving gear. Furthermore, the drive motor 53 and the gear set are both mounted on the pivot portion 231, close to the base 12 on the mounting surface 11, which reduces the impact of the beam 23's sway on the drive motor 53 and the gear set, thereby improving the reliability of the connection between the drive motor 53 and the beam 23. In addition, the drive motor 53 and the gear set are centrally located, which makes it easier to inspect and maintain the drive motor 53 and the gear set.

[0052] In some embodiments, such as Figures 3-5 As shown, the track portion 232 includes a first frame 2321 and a second frame 2323. The two first frames 2321 are arranged opposite each other at a distance. One end of the first frame 2321 is connected to the pivot portion 231, and the other end of the first frame 2321 is connected to the second frame 2323. A mounting groove 2324 is formed between the pivot portion 231, the first frame 2321 and the second frame 2323. The mounting groove 2324 can accommodate the slider 24 so that the slider 24 can slide between the two first frames 2321.

[0053] It should be understood that the mounting groove 2324 extends in a plane parallel to the mounting surface 11, and the sliding member 24 is slidably clamped between the two first frame parts 2321, which improves the connection reliability between the sliding member 24 and the track part 232. This helps to prevent the sliding member 24 from tilting due to the torque from the mold, thereby keeping the mold in an upright posture that is easy to close and reducing the risk of mold tilting. Furthermore, the fact that the sliding member 24 is clamped between the two first frame parts 2321 also improves the connection strength and reliability between the sliding member 24 and the track part 232, thereby enhancing the safety of the mold hoisting device 1.

[0054] In at least one embodiment, such as Figure 5 and Figure 6As shown, the surfaces of the two first frame frames 2321 facing each other are respectively provided with sliding grooves 2322, which are connected to the mounting grooves 2324. The extending direction of the sliding grooves 2322 is parallel to the extending direction of the first frame frames 2321. Further, the sliding member 24 includes a main body 241 and a sliding part 242. The main body 241 is used to install and fix the hoisting assembly 30. The main body 241 is accommodated in the mounting groove 2324. The two sliding parts 242 are respectively connected to the opposite sides of the main body 241 and extend from the main body 241 toward the sliding grooves 2322. The sliding parts 242 can slide in the sliding grooves 2322, so that the main body 241 is slidably clamped between the two first frame frames 2321.

[0055] In at least one embodiment, the first drive component 50 is mounted on the side of the first frame 2321 away from the mounting groove 2324, which makes the structure of the mold hoisting device 1 more compact and helps to avoid interference between the first drive component 50 and the hoisting component 30 mounted on the slider 24.

[0056] In some embodiments, such as Figure 4 and Figure 6 As shown, the boom assembly 20 also includes a connector 25, which includes a first connecting portion 251 and a second connecting portion 252. The first connecting portion 251 is fixedly connected to the slider 52, and the second connecting portion 252 extends from the first connecting portion 251 toward the slider 24. The second connecting portion 252 is fixedly connected to the slider 24, so that the slider 52 can drive the slider 24 to slide along the extension direction of the track portion 232 through the connector 25.

[0057] It should be understood that the first connecting part 251 has several mounting holes for fixed installation with the threaded holes on the slider 52. Two second connecting parts 252 are respectively connected to opposite sides of the first connecting part 251 and extend towards the slider 24. Furthermore, the slider 24 also includes two spaced-apart joints 243 connected to the main body 241. The two joints 243 are fixedly connected to the two second connecting parts 252 in a one-to-one correspondence. This arrangement helps to improve the connection reliability between the connector 25 and the slider 24 and makes the force exerted by the connector 25 on the slider 24 more balanced. In addition, the first connecting part 251, the second connecting part 252 and the slider 24 can surround the outer periphery of the first frame 2321 where the first driving member is provided. In this way, even if the first connecting part 251 is separated from the slider 52 or the slider 24 is detached from the first frame 2321, the connector 25 and the slider 24 can still be hooked on the first frame 2321, which helps to prevent falling and improves the safety of the mold lifting device 1.

[0058] It is worth mentioning that the connector 25 can also be integrally formed with the slider 24 to improve the connection strength between the connector 25 and the slider 24. This application does not impose any specific restrictions on this.

[0059] In some embodiments, such as Figure 8 and Figure 9 As shown, the hoisting assembly 30 includes a fixing member 31, a rotating rod 32, a connector 33, a limiting plate 34, and a limiting disc 35. Specifically, the fixing member 31 is fixedly connected to the sliding member 24. The fixing member 31 has a through groove 311, the extension direction of which is perpendicular to the mounting surface 11. The rotating rod 32 is installed on the fixing member 31 and can move along the through groove 311, that is, it can rotate in the through groove 311 or move along the extension direction of the through groove 311. The connector 33 is installed on the end of the rotating rod 32 facing away from the mounting surface 11 and can be fixed with the lifting hole on the mold. The limiting plate 34 is rotatably connected to the end of the rotating rod 32 facing the mounting surface 11. The limiting plate 34 and the fixing member 31 are separably snapped together to limit the circumferential movement of the rotating rod 32. The limiting disk 35 is rotatably connected to the end of the fixing member 31 facing the mounting surface 11. The limiting disk 35 and the rotating rod 32 are arranged opposite each other along the axial direction of the rotating rod 32 to limit the axial movement of the rotating rod 32. It is understandable that this design helps improve the reliability of the connection between the lifting assembly 30 and the lifting hole on the mold.

[0060] In at least one embodiment, the limiting plate 34 is rotatably connected to the rotating rod 32, and the limiting plate 34 can rotate between an unlocked position and a locked position. When the limiting plate 34 is in the unlocked position, the extension direction of the limiting plate 34 is consistent with the extension direction of the rotating rod 32, and the limiting plate 34 can also move within the through groove 311. When the limiting plate 34 is in the locked position, the extension direction of the limiting plate 34 is perpendicular or nearly perpendicular to the extension direction of the rotating rod 32; and, the fixing member 31 is provided with a plurality of locking grooves 312. When the limiting plate 34 is in the locked position, the limiting plate 34 engages with the locking grooves 312, and thus, through the interaction between the limiting plate 34 and the fixing member 31, the rotating rod 32 is circumferentially limited, which helps to prevent the rotating rod 32 from rotating.

[0061] Furthermore, the limiting disc 35 is rotatably connected to the fixing member 31, allowing the limiting disc 35 to rotate between a clearance position and a stop position. When the limiting disc 35 is in the clearance position, along the axial direction of the rotating rod 32, the limiting disc 35 is offset from the limiting plate 34 and the rotating rod 32, allowing the limiting disc 35 to avoid the limiting plate 34 and the rotating rod 32, and the limiting plate 34 to rotate between an unlocked position and a locked position. When the limiting disc 35 is in the stop position, along the axial direction of the rotating rod 32, the limiting disc 35, the limiting plate 34, and the rotating rod 32 are relatively arranged, allowing the limiting disc 35 to limit the rotating rod 32 and the limiting plate 34 axially, and keeping the limiting plate 34 within the locking groove 312.

[0062] It is worth mentioning that the fixing member 31 can be connected to the sliding member 24 by fasteners, by welding, or by integral molding; the connector 33 can be connected to the rotating rod 32 by fasteners, by welding, or by integral molding; this application does not impose specific limitations in this regard.

[0063] In at least one embodiment, the connector 33 and the rotating rod 32 are connected by fasteners. It should be understood that the connector 33 typically requires higher wear resistance than the rotating rod 32 to ensure reliable connection with the mold and extend its service life. Therefore, the connector 33 and the rotating rod 32 can be made of different materials to balance practicality and cost. Compared to welding, fixing the connector 33 and the rotating rod 32 with fasteners in this embodiment helps avoid the influence of materials on connection strength and reliability. Furthermore, the connector 33 is detachably connected to the rotating rod 32, facilitating replacement of the connector 33. For example, a worn connector 33 can be replaced with a new one, or a different model of connector 33 can be used depending on the mold's lifting holes, thereby increasing the applicability of the mold lifting device 1.

[0064] In some embodiments, such as Figure 10 As shown, the mold hoisting device 1 also includes a counterweight assembly 60, which is installed on the hanger 10. The counterweight assembly 60 includes a support block 61, a counterweight block 62, and a second drive assembly 63. The support block 61 supports the counterweight block 62, and the second drive assembly 63 drives the counterweight block 62 to move in a direction perpendicular to the mounting surface 11. By moving the counterweight block 62, the balance of the mold hoisting device 1 can be adjusted, thereby keeping the mold in an upright posture that is convenient for mold closing and reducing the risk of mold tilting.

[0065] In at least one embodiment, the counterweight assembly 60 includes two spaced-apart support blocks 61 to support the opposite sides of the counterweight block 62, thereby reducing the force exerted by the counterweight block 62 on the second drive assembly 63 and extending the service life of the second drive assembly 63. Furthermore, the second drive assembly 63 is disposed between the two support blocks 61, making the structure of the counterweight assembly 60 more compact.

[0066] In at least one embodiment, the second drive component 63 is implemented as a linear module. It should be understood that there are a large number of linear modules available on the market, which can reduce the design and manufacturing difficulty of the mold hoisting device 1 and reduce the manufacturing cost of the mold hoisting device 1.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made without departing from the spirit and scope of the invention, and all such changes and modifications fall within the scope of the invention as claimed.
