Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a traction wheel casting mold. Background Technology

[0002] The traction sheave is a key casting on the elevator traction machine. The traction sheave is the rope sheave on the traction machine, also known as the traction rope sheave or drive rope sheave. It is the device that transmits traction power in the elevator. It transmits power by utilizing the friction between the traction steel wire rope and the rope groove on the edge of the traction sheave. When manufacturing and processing the traction sheave, a traction sheave casting mold is required.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] In one embodiment, such as Figures 1-8 As shown, a traction wheel casting mold includes a base 1, a support plate 2 fixedly mounted on the upper surface of the base 1, a positioning sleeve 44 fixedly connected to the middle of the upper surface of the support plate 2, an installation plate 14 inserted into the positioning sleeve 44, a lower mold 3 fixedly connected to the upper surface of the installation plate 14, an upper mold 4 located directly above the lower mold 3, a wheel body 6 located between the upper mold 4 and the lower mold 3, and a pouring gate opened on the upper surface of the upper mold 4. The mold also includes:

[0036] An adjustment component is provided on the base 1 and is used to adjust the height of the upper mold 4;

[0037] The first mounting component is disposed on the upper surface of the upper mold 4 and is used to mount the upper mold 4;

[0038] The second mounting component is symmetrically arranged on the surface of the positioning sleeve 44 and is used to mount the lower mold 3;

[0039] The ejector assembly is symmetrically positioned at the bottom of the lower mold 3 and is used to eject the wheel body 6.

[0040] In this embodiment, when the wheel body 6 needs to be produced, the upper mold 4 and the lower mold 3 are fixedly installed using the first and second installation components. After the upper mold 4 and the lower mold 3 are installed, the height of the upper mold 4 is adjusted using the adjustment component. After the upper mold 4 and the lower mold 3 are completely closed, the production material is poured into the cavity between the upper mold 4 and the lower mold 3 through the pouring port. At this time, the casting production process of the wheel body 6 can be realized. After the wheel body 6 is produced, the height position of the upper mold 4 is adjusted using the adjustment component. During the upward movement of the upper mold 4, the ejection component will also simultaneously eject the wheel body 6 from the lower mold 3. At this time, it is convenient for the staff to demold and take out the wheel body 6 after production, which effectively improves the overall practicality and convenience of the device.

[0041] In one embodiment, such as Figures 1-4 As shown, the adjustment assembly includes an adjustment plate 5 fixedly connected to the upper surface of the base 1. A drive motor 7 is fixedly connected to the upper surface of the adjustment plate 5. The output shaft of the drive motor 7 is fixedly connected to a threaded rod 8 via a coupling. The other end of the threaded rod 8 is rotatably connected to the inner wall of the adjustment plate 5. A threaded block 9 is threadedly connected to the outer wall of the threaded rod 8. A movable groove for the threaded block 9 to move is opened on the surface of the adjustment plate 5. A connecting frame 10 is fixedly installed on the surface of the threaded block 9. A bottom frame 24 is fixedly connected to the bottom of the connecting frame 10. An installation plate 18 is inserted into the bottom frame 24. The bottom of the installation plate 18 is fixedly connected to the upper surface of the upper mold 4. When the height of the upper mold 4 needs to be adjusted, the drive motor 7 starts to run. At this time, the drive motor 7 will drive the threaded rod 8 to rotate synchronously. The threaded block 9 will move synchronously on the outer wall of the threaded rod 8, driving the connecting frame 10 and the bottom frame 24 to move synchronously. The bottom frame 24 will then drive the installation plate 18 and the upper mold 4 to move synchronously. At this time, the height of the upper mold 4 can be adjusted.

[0042] In one embodiment, such as Figure 2 and Figure 5As shown, the first mounting assembly includes an inner plate 19 fixedly connected to the middle of the inner wall of the mounting plate 18. Slide rods 20 are symmetrically arranged on both sides of the inner plate 19. The other end of each slide rod 20 is fixedly connected to the inner wall of the mounting plate 18. A moving block 21 is slidably connected to the outer wall of every two slide rods 20. A return spring 22 is sleeved on the outside of each slide rod 20, and the return spring 22 abuts against the moving block 21 and the inner plate 19. An arc-shaped block 23 is fixedly connected to the surface of the moving block 21. Mounting grooves for the arc-shaped blocks 23 to move are provided on the surfaces of both the mounting plate 18 and the bottom frame 24. When the upper mold 4 needs to be installed, the mounting plate 18 is simply inserted into the bottom frame 24. When the mounting plate 18 moves synchronously, the arc-shaped block 23 moves synchronously. When the arc-shaped block 23 enters the bottom frame 24, it is squeezed. At this time, the arc-shaped block 23 moves synchronously on the outer wall of the slide bar 20, and the moving block 21 squeezes the return spring 22 during the movement. When the mounting plate 18 moves the arc-shaped block 23 into the mounting groove on the surface of the bottom frame 24, the return spring 22 resets and moves synchronously with the moving block 21 and the arc-shaped block 23. When the arc-shaped block 23 is inserted into the mounting groove on the surface of the bottom frame 24, the mounting plate 18 and the bottom frame 24 can be fixed. At this time, the upper mold 4 can be installed.

[0043] In one embodiment, such as Figure 2 and Figure 6 As shown, the surface of the bottom frame 24 is symmetrically provided with storage plates 25. A support block 26 is fixedly connected to the middle of the inner wall of the storage plate 25. Both sides of the support block 26 are fixedly connected to connecting blocks 28 through damping rods 27. A stop spring 29 is sleeved on the outside of the damping rod 27. The stop spring 29 abuts against the connecting block 28 and the support block 26. A connecting rod 30 is fixedly connected to the surface of the connecting block 28. A pressing plate 31 is fixedly connected to the other end of every two connecting rods 30. An extrusion plate 32 is fixedly connected to the surface of the pressing plate 31. When it is necessary to disassemble the upper mold 4, simply press the pressing plate 31. At this time, the pressing plate 31 will drive the extrusion plate. 32 moves synchronously. When the pressing plate 32 presses the arc-shaped block 23 into the mounting groove that is detached from the surface of the bottom frame 24, the upper mold 4 is pulled down. At this time, the upper mold 4 will drive the mounting plate 18 to move synchronously. When the mounting plate 18 is detached from the bottom frame 24, the upper mold 4 can be disassembled. During the movement of the pressing plate 31, it will also drive the connecting rod 30 and the connecting block 28 to move synchronously. At this time, the connecting block 28 will press the damping rod 27 and the resisting spring 29. When the operator releases the pressing plate 31, the resisting spring 29 will reset, thereby driving the pressing plate 31 and the pressing plate 32 to reset synchronously.

[0044] In one embodiment, such as Figures 1-4As shown, guide rods 11 are symmetrically arranged on the upper surface of the support plate 2. The other end of the guide rod 11 is fixedly connected to the limiting plate 12. The outer wall of the guide rod 11 is slidably connected to the guide plate 13. The surface of the guide plate 13 is fixedly connected to the surface of the connecting frame 10. During the movement of the connecting frame 10, the guide plate 13 will also move synchronously on the outer wall of the guide rod 11. At this time, the guide plate 13 and the guide rod 11 can effectively play the role of limiting and guiding, thereby effectively improving the stability of the upper mold 4 during the movement.

[0045] In one embodiment, such as Figure 3 and Figure 7 As shown, the second mounting assembly includes a fixing plate 15 symmetrically arranged on the surface of the positioning sleeve 44. Inner rods 34 are symmetrically mounted on the inner wall of the fixing plate 15. A contact plate 35 is slidably connected to the outer wall of every two inner rods 34. A compression spring 36 is sleeved on the outside of each inner rod 34, and the compression spring 36 abuts against the contact plate 35 and the fixing plate 15. A pull ring is fixedly connected to one side of the contact plate 35 via a side plate 37, and an insertion rod 38 is fixedly connected to the other side of the contact plate 35. Slots for the insertion rod 38 are provided on the contact surfaces of the fixing plate 15 and the positioning sleeve 44, as well as on the surface of the mounting plate 14. When it is necessary to install the lower mold 3, only... First, pull the ring. The ring will move the side plate 37 synchronously. The side plate 37 will then move the contact plate 35 synchronously on the outer wall of the inner rod 34. During the movement of the contact plate 35, it will compress the compression spring 36. The contact plate 35 will also move the insertion rod 38 synchronously. Then, insert the mounting plate 14 into the positioning sleeve 44 and release the ring. The compression spring 36 will then return to its original position, moving the contact plate 35 and the insertion rod 38 synchronously. When the insertion rod 38 is inserted into the slot on the surface of the mounting plate 14, the lower mold 3 can be installed. This also makes it easier for workers to disassemble and replace the lower mold 3.

[0046] In one embodiment, such as Figure 4 and Figure 8As shown, the ejector assembly includes connecting sleeves 39 symmetrically installed at the bottom of the lower mold 3. A movable disk 40 is provided inside the connecting sleeve 39. A push rod 41 is fixedly connected to the upper surface of the movable disk 40. A sliding groove for the push rod 41 to move is opened through the bottom of the lower mold 3. A connecting spring 42 is sleeved on the outside of the push rod 41, and the connecting spring 42 abuts against the movable disk 40 and the connecting sleeve 39. A push rod 43 is fixedly connected to the bottom of the movable disk 40. A threaded plate 16 is threadedly connected to the outer wall of the threaded rod 8. A movable groove for the threaded plate 16 to move is opened on the surface of the adjusting plate 5. A support frame 17 is fixedly connected to the surface of the threaded plate 16. The bottom end of the push rod 43 contacts the upper surface of the support frame 17. During the upward movement of the upper mold 4 (i.e., during the rotation of the threaded rod 8), the threaded plate 16 moves synchronously on the outer wall of the threaded rod 8, driving the support... The support frame 17 moves synchronously. During the upward movement of the support frame 17, it will press the push rod 43. At this time, the push rod 43 will drive the moving plate 40 and the ejector rod 41 to move upward synchronously. During the upward movement of the ejector rod 41, the wheel 6 inside the lower mold 3 can be effectively ejected, making it easier for the workers to remove the wheel 6 from the mold (the opening of the upper mold 4 and the ejection of the wheel 6 are carried out synchronously). During the upward movement of the moving plate 40, it will also press the connecting spring 42. When the support frame 17 moves downward, the connecting spring 42 will reset, which will drive the moving plate 40, the ejector rod 41 and the push rod 43 to reset synchronously (the support plate 2 has a through hole for the connecting sleeve 39 to move, so it will not affect the disassembly and assembly of the lower mold 3, but can play a certain positioning role).

[0047] In one embodiment, such as Figures 1-4 As shown, sealing gaskets are bonded to the contact surfaces of the upper mold 4 and the lower mold 3. The sealing gaskets effectively improve the sealing between the upper mold 4 and the lower mold 3, thereby preventing leakage between the upper mold 4 and the lower mold 3 and affecting the production quality of the wheel body 6.

[0048] The above embodiment discloses a traction wheel casting mold. When the wheel body 6 needs to be produced, the mounting plate 18 and the bottom frame 24 are first fixed together by the arc block 23. At this time, the upper mold 4 can be installed, and the lower mold 3 is installed by the cooperation between the pull ring and the insert rod 38. After the upper mold 4 and the lower mold 3 are installed, the drive motor 7 starts to run, driving the threaded rod 8 to rotate synchronously. At this time, the height of the upper mold 4 can be adjusted. After the upper mold 4 and the lower mold 3 are completely closed, the production raw materials are poured into the space between the upper mold 4 and the lower mold 3 through the pouring port. Inside the cavity, the casting and production of wheel body 6 can be realized. After the wheel body 6 is produced, the drive motor 7 reverses, which can drive the upper mold 4 to move upward. During the upward movement of the upper mold 4 (i.e. during the reverse movement of the threaded rod 8), the support frame 17 will squeeze the push rod 43. At this time, the push rod 43 will drive the moving plate 40 and the ejector rod 41 to move upward synchronously. During the upward movement of the ejector rod 41, the wheel body 6 in the lower mold 3 can be effectively ejected. At this time, it is convenient for the staff to demold and take away the wheel body 6 after production, which effectively improves the overall practicality and convenience of the device.
