Description

Technical Field

[0001] This application relates to the field of mold manufacturing, and in particular to a mold mounting structure. Background Technology

[0002] In manufacturing processes such as injection molding, stamping, and die casting, molds serve as the core tooling for mass production. Their production process can be summarized as follows: hoisting the mold onto the machine tool table → aligning it with the positioning support plate and locking it → connecting the temperature control and injection system → starting continuous production. The entire process places extremely high demands on the installation accuracy, mold change speed, and operational safety of the mold. Any deviation will directly affect the product dimensional accuracy and production efficiency.

[0003] In actual production, molds are frequently changed: on the one hand, the order model of multiple varieties and small batches requires the same machine tool to switch different molds multiple times a day; on the other hand, molds need to be taken off the production line regularly for maintenance, cleaning or repair. Due to the large weight and high center of gravity of the molds, when changing molds, it is common to use a manual hoist to lift the mold, and then manually move the mold to make fine adjustments by using pry bars and rollers, and then fix it.

[0004] Traditionally, after hoisting the mold with a hoist, workers use crowbars and rollers to move the mold for fine adjustments. This is not only time-consuming and labor-intensive, but also carries the risk of the mold tipping over, injuring personnel, or damaging expensive mold cavities. Utility Model Content

[0005] The purpose of this application is to address the problem mentioned in the background art that the traditional method of manually lifting the mold with a hoist and then manually moving the mold with crowbars and rollers for fine adjustments is not only time-consuming and labor-intensive, but also poses the risk of mold tipping over, injuring personnel, or damaging expensive mold cavities. This application provides a mold mounting structure.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: A mold mounting structure includes a mold platform with two symmetrical support plates slidably connected to it. A production mold is positioned between the two support plates. A lifting frame is mounted on the mold platform, and the lifting frame rests against the ground. A manual hoist is mounted on the lifting frame, and a mounting mechanism is provided between the manual hoist and the lifting frame. An adjusting chain is driven to the manual hoist, and a lifting chain is driven to the manual hoist. A lifting hook is mounted on the lifting chain, and a quick-release limiting mechanism is provided between the lifting chain and the lifting hook. A lifting strap is hung on the lifting hook and is fixedly fitted to the production mold. A latching rod is rotatably connected to the lifting hook, and a U-shaped spring plate is provided between the latching rod and the lifting hook. Both ends of the spring plate are fixedly connected to the latching rod and the lifting hook. A controller is fixed on the mold platform.

[0007] By adopting the above technical solution, the hoisting mechanism on the hoisting frame drives the manual hoist to move, allowing the manual hoist to quickly adjust the position of the hoisted production mold. This makes it easier to align the production mold with the installation position on the support plate when installing the mold on the mold platform, reducing the possibility that the installation workers will have difficulty pushing and adjusting the mold due to its weight.

[0008] Furthermore, the upper hoisting mechanism includes a sliding block slidably connected to the hoisting frame, a threaded rod rotatably connected to the hoisting frame, the threaded rod passing through the sliding block and being threadedly connected to the sliding block, a drive motor fixed to one end of the hoisting frame, the output end of the drive motor passing through the hoisting frame and being fixedly connected to the threaded rod, a moving rod fixed to the sliding block, a moving component provided on the moving rod, and a limit component provided between the moving rod and the hoisting frame.

[0009] By adopting the above technical solution, when the sliding block moves on the hoisting frame, it drives the moving rod, allowing the moving component to move on the moving rod. The moving component drives the manual hoist, which makes it convenient and quick to adjust the position of the production mold during installation, reducing the possibility that the installation workers will have to exert a lot of effort to adjust the production mold due to its weight.

[0010] Furthermore, the moving component includes a second sliding block slidably connected to the moving rod, a second threaded rod rotatably connected to the moving rod, the second threaded rod passing through the second sliding block and being threadedly connected to the second sliding block, a second drive motor fixed to one end of the moving rod, the output end of the second drive motor passing through the moving rod and being fixedly connected to the second threaded rod, and the second sliding block being fixedly connected to the manual hoist.

[0011] By adopting the above technical solution, the second threaded rod drives the second sliding block, which moves along the moving rod, thus making it convenient for the second sliding block to drive the manual hoist to move along the moving rod.

[0012] Furthermore, the limiting assembly includes two limiting rods symmetrically fixed on the moving rod, a limiting block fixed between the two limiting rods, and two symmetrical stop rods fixed on the hoisting frame, with the limiting block located between the two stop rods.

[0013] By adopting the above technical solution, when the sliding block moves the moving rod, the moving rod moves the limiting rod, and the limiting rod moves the limiting block between the two stops on the hoisting frame, thereby further improving the stability of the moving rod support.

[0014] Furthermore, a movable wheel is rotatably connected to the limiting block, and the movable wheel is located between the two stop levers and is in rolling connection with the stop levers.

[0015] By adopting the above technical solution, when the limiting block moves, it drives the moving wheel to move between the two stop levers, thereby facilitating the movement of the limiting block between the two stop levers and reducing the friction between the limiting block and the stop levers.

[0016] Furthermore, the quick-release limiting mechanism includes a support pulley frame rotatably connected to the lifting chain, a connecting block provided on the support pulley frame, the connecting block being fixedly connected to the lifting hook, a sliding groove provided on the support pulley frame, the connecting block being located within the sliding groove, one end of the sliding groove being open, a locking block slidably connected on the support pulley frame, the locking block penetrating the support pulley frame, with one end located within the sliding groove, an inclined surface being provided on the side of the locking block facing the opening of the sliding groove, a limiting spring provided between the locking block and the support pulley frame, both ends of the limiting spring being fixedly connected to the support pulley frame and the locking block, and a blocking component provided on the latching rod.

[0017] By adopting the above technical solution, the connecting block is locked in the sliding groove on the supporting pulley frame, and the locking block is used to limit the connection block, thereby making it easy to replace the lifting hook on the connecting block. Furthermore, the blocking assembly includes a support block fixed to the latching rod, a movable threaded rod threaded through the support block, a blocking block rotatably connected to one end of the movable threaded rod, the blocking block being slidably connected to the latching rod, and a knob fixed to the end of the movable threaded rod away from the blocking block.

[0018] By adopting the above technical solution, the moving threaded rod drives the blocking block to move, and the blocking block is positioned between the buckle rod and the lifting hook, thereby further reducing the possibility of the lifting sling coming off the hook after it is fitted onto the lifting hook.

[0019] Furthermore, four symmetrical fixing bolts are fixed on the production mold, and fixing bolts corresponding to the fixing bolts are fixed on the support plate. The threads of fixing bolts one and two are opposite. A double-ended nut is provided between fixing bolts one and two. The double-ended nut is threadedly connected to fixing bolts one and two.

[0020] By adopting the above technical solution, corresponding fixing bolt one and fixing bolt two are fixed on the production mold and the support plate. Double-headed nuts are simultaneously screwed onto fixing bolt one and fixing bolt two, which facilitates the connection, fixing and disassembly of the production mold and the support plate.

[0021] In summary, this application includes at least one of the following beneficial effects; 1. In this application, a controller is used to control a drive motor, which in turn drives a threaded rod to rotate. The threaded rod then drives a sliding block, which slides on the lifting frame. This sliding block drives a moving rod, which in turn drives a second sliding block. The second sliding block then drives a manual hoist, moving the hoist to the center of the mold table. The controller then controls a second drive motor, which drives another sliding block, which in turn moves the manual hoist from above the mold table. After the production mold, equipped with a lifting strap, is hung on the lifting hook, the manual hoist drives the lifting chain to... The lifting chain drives the lifting hook, and after the production mold is raised, the second drive motor drives the second threaded rod, which in turn moves the second sliding block to move the production mold above the mold platform, between the two support plates. Then, the controller controls the first and second drive motors to make fine adjustments to the position of the production mold, aligning it with the installation position of the support plates. This allows for convenient and quick adjustments to the position of the production mold during installation, reducing the effort required for installation workers due to the weight of the production mold.

[0022] 2. This application, by rotating a knob when the lifting sling is hooked onto the lifting hook after passing over the locking bar, moves the threaded rod on the support block. The support block, along with a blocking block, blocks between the locking bar and the lifting hook. The upper limit groove of the locking bar and the blocking block cooperate to restrict the locking bar. When the lifting hook needs to be replaced, the locking block is pulled, moving it on the support pulley frame and pulling the limit spring. Then, the connecting block moves the lifting hook out of the sliding groove on the support pulley frame. A new connecting block and lifting hook are then removed, and the connecting block is inserted into the sliding groove on the support pulley frame. The connecting block presses against the inclined surface of the locking block, moving the locking block away from the support pulley frame. When the connecting block passes the locking block, the locking block returns to its original position under the pull of the limit spring, completing the replacement of the lifting hook. This achieves the purpose of facilitating the replacement of damaged lifting hooks, improving the stability of lifting hook use, and reducing the possibility of lifting sling detachment.

[0025] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0026] This application discloses a mold mounting structure.

[0027] Reference Figure 1 , Figure 2 and Figure 3A mold mounting structure includes a mold platform 1, on which two symmetrical support plates 3 are slidably connected. A production mold 2 is disposed between the two support plates 3. A lifting frame 6 is disposed on the mold platform 1, and the lifting frame 6 is in contact with the ground. A manual hoist 9 is disposed on the lifting frame 6. A mounting mechanism 5 is disposed between the manual hoist 9 and the lifting frame 6. An adjusting chain 11 is driven to the manual hoist 9. A lifting chain 10 is driven to the manual hoist 9. A lifting hook 7 is disposed on the lifting chain 10. A quick-release limiting mechanism 8 is disposed between the lifting chain 10 and the lifting hook 7. A lifting strap 4 is hung on the lifting hook 7. The lifting strap 4 is sleeved and fixed to the production mold 2. A buckle rod 12 is rotatably connected to the lifting hook 7. A U-shaped spring plate 13 is disposed between the buckle rod 12 and the lifting hook 7. Both ends of the spring plate 13 are fixedly connected to the buckle rod 12 and the lifting hook 7. A controller 17 is fixed on the mold platform 1.

[0028] When it is necessary to install the production mold 2, firstly, the upper hoisting mechanism 5 on the hoisting frame 6 is used to drive the manual hoist 9, so that the hoisting chain 10 on the manual hoist 9 drives the hoisting hook 7 to move outside the mold platform 1, and the production mold 2 is moved to the ground on one side of the mold platform 1. The hoisting strap 4 is then placed on the hoisting hook 7 and the production mold 2. The hoisting strap 4 squeezes the buckle rod 12, so that the buckle rod 12 squeezes the spring plate 13. After the hoisting strap 4 passes the buckle rod 12, it is hooked on the hoisting hook 7. The installer pulls the adjusting chain 11 to retract the hoisting chain 10 on the manual hoist 9, so that the hoisting hook 7 drives the hoisting strap 4, and the hoisting strap 4 drives the production mold 2. The installer uses the controller 17 to control the upper hoisting mechanism 5 to hoist the production mold 2. Mechanism 5 drives the manual hoist 9 to move, causing the production mold 2 on the lifting hook 7 to move as well. The position of the production mold 2 between the two support plates 3 is adjusted, and then the production mold 2 is fixed on the corresponding support plate 3, completing the mold installation. If the lifting hook 7 is damaged, the quick-release limit mechanism 8 can be used to quickly disassemble and replace the lifting hook 7. By using the lifting mechanism 5 on the lifting frame 6 to drive the manual hoist 9 to move, the manual hoist 9 can quickly adjust the position of the lifted production mold 2. This makes it easier to align the production mold 2 with the installation position on the support plate 3 when installing the mold on the mold platform 1, reducing the possibility that the installation workers will have difficulty pushing and adjusting the mold due to its weight.

[0029] Reference Figure 1 and Figure 2The hoisting mechanism 5 includes a sliding block 51 slidably connected to the hoisting frame 6. A threaded rod 52 is rotatably connected to the hoisting frame 6. The threaded rod 52 passes through the sliding block 51 and is threadedly connected to the sliding block 51. A drive motor 53 is fixed to one end of the hoisting frame 6. The output end of the drive motor 53 passes through the hoisting frame 6 and is fixedly connected to the threaded rod 52. A moving rod 54 is fixed to the sliding block 51. A moving component 55 is provided on the moving rod 54. A limit component 56 is provided between the moving rod 54 and the hoisting frame 6.

[0030] In addition, the moving component 55 includes a second sliding block 551 slidably connected to the moving rod 54, a second threaded rod 552 rotatably connected to the moving rod 54, the second threaded rod 552 passing through the second sliding block 551 and being threadedly connected to the second sliding block 551, a second drive motor 553 fixed to one end of the moving rod 54, the output end of the second drive motor 553 passing through the moving rod 54 and being fixedly connected to the second threaded rod 552, and the second sliding block 551 being fixedly connected to the manual hoist 9.

[0031] Furthermore, the limiting assembly 56 includes two limiting rods 561 symmetrically fixed on the moving rod 54, a limiting block 562 fixed between the two limiting rods 561, and two symmetrical stop rods 563 fixed on the hoisting frame 6, with the limiting block 562 located between the two stop rods 563.

[0032] Furthermore, a movable wheel 564 is rotatably connected to the limiting block 562. The movable wheel 564 is located between the two stop levers 563 and is in rolling connection with the stop levers 563.

[0033] The controller 17 controls the drive motor 53, which drives the threaded rod 52 to rotate. The threaded rod 52 drives the sliding block 51, which slides on the lifting frame 6. The sliding block 51 drives the moving rod 54, which drives the second sliding block 551. The second sliding block 551 drives the manual hoist 9, moving it to the middle position of the mold table 1. Then, the controller 17 controls the drive motor 553, which drives the second sliding block 551. 51 drives the manual hoist 9 to move out from above the mold table 1. After the production mold 2, which is equipped with the lifting belt 4, is hung on the lifting hook 7, the manual hoist 9 drives the lifting chain 10, which in turn drives the lifting hook 7. After the production mold 2 is raised, the drive motor 2553 drives the threaded rod 552, which in turn drives the sliding block 551 to move the production mold 2 above the mold table 1, so that the production mold 2 is moved between the two support plates 3. Then, the controller 17 controls the drive motor 153 and the drive motor 2552. 553. Make fine adjustments to the position of the production mold 2 to align it with the installation position of the support plate 3. When the sliding block 51 drives the moving rod 54 to move on the lifting frame 6, the moving rod 54 drives the limiting rod 561, which in turn drives the limiting block 562. The limiting block 562, supported by the moving wheel 564, moves between the two stop bars 563. The limiting rod 561 further supports the moving rod 54, improving its stability. The production mold 2 and the support plate 3 are then fixed. After they are fixed together, release the lifting strap 4 and move the manual hoist 9 to one side of the lifting frame 6. By moving the moving rod 54 along the lifting frame 6 with the support of the sliding block 51, the sliding block 551 drives the manual hoist 9 to move along the moving rod 54, and the lifting hook 7 on the manual hoist 9 drives the production mold 2 to move. This makes it convenient and quick to adjust the position of the production mold 2 when it is installed, reducing the possibility that the installation workers will have to exert more effort to adjust it because the production mold 2 is heavy.

[0034] Reference Figure 1 and Figure 3 The quick-release limiting mechanism 8 includes a support pulley frame 81 rotatably connected to the lifting chain 10. A connecting block 82 is provided on the support pulley frame 81. The connecting block 82 is fixedly connected to the lifting hook 7. A sliding groove is provided on the support pulley frame 81. The connecting block 82 is located in the sliding groove. One end of the sliding groove is open. A locking block 83 is slidably connected on the support pulley frame 81. The locking block 83 passes through the support pulley frame 81, and one end is located in the sliding groove. An inclined surface is provided on the side of the locking block 83 facing the opening of the sliding groove. A limiting spring 84 is provided between the locking block 83 and the support pulley frame 81. Both ends of the limiting spring 84 are fixedly connected to the support pulley frame 81 and the locking block 83. A blocking component 85 is provided on the latch rod 12.

[0035] Additionally, the blocking assembly 85 includes a support block 851 fixed to the latching rod 12. A movable threaded rod 853 is threadedly connected through the support block 851. One end of the movable threaded rod 853 is rotatably connected to a blocking block 852. The blocking block 852 is slidably connected to the latching rod 12. A knob 854 is fixed to the end of the movable threaded rod 853 away from the blocking block 852.

[0036] When the lifting sling 4 is hooked onto the lifting hook 7 after passing over the locking rod 12, turn the knob 854 to move the threaded rod 853 on the support block 851. The support block 851 moves the blocking block 852 between the locking rod 12 and the lifting hook 7. The upper limit groove of the locking rod 12 and the blocking block 852 cooperate to restrict the locking rod 12. When the lifting hook 7 needs to be replaced, pull the locking block 83 to move it on the support pulley frame 81 and pull the limit spring 84. Then, the connecting block 82 moves the lifting hook 7 out of the sliding groove on the support pulley frame 81. Then, take out the new connecting block 82 and the lifting hook 7, and insert the connecting block 82 into the support pulley frame 81. In the sliding groove, the connecting block 82 presses against the inclined surface of the locking block 83, causing the locking block 83 to move away from the supporting pulley frame 81. When the connecting block 82 passes the locking block 83, the locking block 83 is reset under the pull of the limiting spring 84, completing the replacement of the lifting hook 7. By using the connecting block 82 to support the lifting hook 7, the connecting block 82 is slidably connected to the supporting pulley frame 81, and then the locking block 83 is used for limiting. At the same time, when using the lifting hook 7, the blocking block 852 is used to further limit the locking rod 12 on the lifting hook 7, thereby facilitating the replacement of the damaged lifting hook 7, improving the stability of the lifting hook 7, and reducing the possibility of the lifting sling 4 disengaging.

[0037] Reference Figure 1 and Figure 4Four symmetrical fixing bolts 14 are fixed on the production mold 2. Fixing bolts 15 corresponding to fixing bolts 14 are fixed on the support plate 3. The threads of fixing bolts 14 and 15 are opposite. A double-ended nut 16 is provided between fixing bolts 14 and 15. The double-ended nut 16 is threaded to fixing bolts 14 and 15. After hoisting the production mold 2 between the two support plates 3, adjust the position of the production mold 2 so that the fixing bolt 14 on the production mold 2 is aligned with the fixing bolt 15 on the support plate 3. Then, position the double-ended nut 16 between the fixing bolt 14 and the fixing bolt 15, and rotate the double-ended nut 16 to connect it with the fixing bolt 14 and the fixing bolt 15 by thread, thus completing the fixation of the production mold 2 to the support plate 3. At the same time, the two ends of the double-ended nut 16 are flared, which makes it easier for the fixing bolt 14 and the fixing bolt 15 to align with the double-ended nut 16. By fixing the corresponding fixing bolt 14 and fixing bolt 15 on the production mold 2 and the support plate 3, and by simultaneously screwing the double-ended nut 16 onto the fixing bolt 14 and the fixing bolt 15, the connection, fixation and removal of the production mold 2 and the support plate 3 can be easily achieved.

[0038] Working principle: When it is necessary to install the production mold 2, the controller 17 controls the drive motor 53, which drives the threaded rod 52 to rotate. The threaded rod 52 drives the sliding block 51, which slides on the lifting frame 6. The sliding block 51 drives the moving rod 54, which drives the second sliding block 551. The second sliding block 551 drives the manual hoist 9, which moves to the middle position of the mold table 1. Then, the controller 17 controls the drive motor 553, which drives the second sliding block 551, which in turn drives the manual hoist 9. Moving from above the mold platform 1, after the production mold 2, equipped with the lifting strap 4, is hung on the lifting hook 7, and the lifting strap 4 is then hung on the hook 7 over the buckle rod 12, the knob 854 is turned to move the threaded rod 853 on the support block 851. The support block 851 drives the blocking block 852 to block between the buckle rod 12 and the lifting hook 7. The upper limit groove of the buckle rod 12 and the blocking block 852 cooperate to restrict the buckle rod 12. Then, the manual hoist 9 drives the lifting chain 10, which in turn drives the lifting hook 7. After the production mold 2 is raised, the drive motor 2553 drives the threaded rod 255. 2. Move the production mold 2 above the mold table 1 using the sliding block 551, positioning it between the two support plates 3. Then, use the controller 17 to control the drive motors 53 and 553 to finely adjust the position of the production mold 2, aligning the fixing bolt 14 on the production mold 2 with the fixing bolt 15 on the support plate 3. Position the double-ended nut 16 between the fixing bolts 14 and 15, and rotate the double-ended nut 16 to thread it onto the fixing bolts 14 and 15, thus completing the connection between the production mold 2 and the support plate 3. When the lifting hook 7 needs to be replaced, pull the locking block 83 to move it on the support pulley frame 81 and pull the limit spring 84. Then, the connecting block 82 will drive the lifting hook 7 to slide out of the sliding groove on the support pulley frame 81. Then, take out the new connecting block 82 and the lifting hook 7, insert the connecting block 82 into the sliding groove on the support pulley frame 81, and the connecting block 82 will press the inclined surface of the locking block 83 to move the locking block 83 away from the support pulley frame 81. When the connecting block 82 passes the locking block 83, the locking block 83 will be reset under the pull of the limit spring 84, thus completing the replacement of the lifting hook 7.
