Description

Technical Field

[0001] The invention relates to the technical field of centrifugal casting, in particular to a processing centrifugal casting mold. Background Art

[0002] Centrifugal casting is a technology and method of injecting liquid metal into a high-speed rotating mold, causing the molten metal to perform centrifugal motion to fill the mold and form a casting. After the casting is completed, the existing centrifugal casting mold needs to be slowly stopped and then the casting is taken out. The existing mold is generally stopped by stopping the driving device, allowing the mold to rotate freely for a period of time, and then using friction resistance to slowly stop it. However, in this way, the energy stored in the mold containing the casting when it rotates will be completely wasted, and the downtime of the mold will also be extended, reducing work efficiency. For this reason, we propose a method for processing a centrifugal casting mold. Summary of the invention

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1-Figure 9 The present invention provides a technical solution: a centrifugal casting mold, comprising a base 1 and a mold arranged on the base 1, and also comprising:

[0041] Axle 1 2 is fixedly connected to the mold and rotatably connected to the base 1;

[0042] The driving assembly 3 is arranged on the base 1 and connected with the shaft 2 to drive the shaft 2 to rotate so as to rotate the mold;

[0043] The switching component 4 is arranged on the base 1 and connected to the driving component 3;

[0044] The energy recovery component 5 is arranged on the base 1, and the switching component 4 is used to disconnect the connection between the driving component 3 and the shaft 1 2, and at the same time drive the energy recovery component 5 to connect with the shaft 1 2 to recover energy;

[0045] During specific operation, the slide tube 42 is pushed to disconnect the shaft 1 2 from the drive motor 32, and the drive motor 32 is stopped by a program, and the shaft 1 2 is connected to the coil spring 38, so that the energy of the mold rotation is recovered and stored;

[0046] After the casting is taken out, the slide tube 42 is pushed continuously to release the energy of the coil spring 38 to drive the mold to rotate alone. At this time, it can be used to cooperate with the staff to clean the inner wall of the mold or spray the release agent. At the same time, after the mold rotates a certain number of times, the slide tube 42 will be automatically reset to collect the energy of the mold rotation again.

[0047] At the same time, after the slide tube 42 is reset, the coil spring 38 can be reset and can work together with the drive motor 32 to drive the mold to rotate, so that the drive motor 32 does not need to work at a high load, thereby increasing the life of the device.

[0048] The driving assembly 3 includes a gear plate 1 31 fixedly connected to the shaft 1 2, a driving motor 32 fixedly connected to the base 1, a shaft 2 33 fixedly connected to the output shaft of the driving motor 32, a gear plate 2 34 meshing with the gear plate 1 31 is provided on the shaft 2 33, and the driving motor 32 is started to drive the gear plate 2 34 to rotate, thereby driving the gear plate 1 31 to rotate, and then driving the shaft 1 2 to rotate.

[0049] The energy recovery component 5 includes a mounting frame 35 fixedly connected to the base 1, and a shaft three 36 is rotatably connected to the mounting frame 35 through a bearing. A circular shell 37 is fixedly connected to the mounting frame 35. One end of the shaft three 36 passes through the circular shell 37 and is fixedly connected to a disc spring 38. One end of the disc spring 38 is fixedly connected to the circular shell 37. A hollow shaft four 39 is provided on the shaft three 36. Rotating the hollow shaft four 39 drives the shaft three 36 to rotate, thereby causing the disc spring 38 to twist and store force.

[0050] The switching assembly 4 includes a slide bar 41 fixedly connected to the mounting frame 35, a slide tube 42 is sleeved on the slide bar 41, a support frame 43 is fixedly connected to the slide tube 42, a hollow shaft 43 is rotatably connected to the support frame 43 through a bearing, and a toothed disc 3 44 is fixedly connected to the shaft 1 2, and a toothed disc 4 45 is fixedly connected to the hollow shaft 4 39. When switching, the movable slide tube 42 drives the hollow shaft 4 39 to move, thereby driving the toothed disc 4 45 to move and engage with the toothed disc 3 44, while the toothed disc 2 34 is disengaged from the toothed disc 1 31;

[0051] A hollow shaft 5 46 is sleeved on the shaft 2 33, and the hollow shaft 5 46 is fixedly connected to the gear disc 2 34, and a sliding protrusion 1 47 is fixedly connected to the inner wall of the hollow shaft 5 46, and a sliding groove 1 48 is provided on the shaft 2 33, and one end of the sliding protrusion 1 47 is located in the sliding groove 1 48 and is slidably connected to the inner wall thereof, and a sliding plate 49 is fixedly connected to one end of the sliding tube 42, and one end of the sliding plate 49 is rotatably connected to the hollow shaft 5 46 through a bearing, and the sliding tube 42 is moved to drive the sliding plate 49 to move, thereby driving the hollow shaft 5 46 to move, and then driving the gear disc 2 34 to move away from the gear disc 1 31;

[0052] A second sliding protrusion 51 is fixedly connected inside the hollow shaft 4 39 , and a second sliding groove 52 is provided on the shaft 36 . One end of the second sliding protrusion 51 is located in the second sliding groove 52 and is slidably connected to the inner wall thereof.

[0053] The toothed disc 3 44 is designed to have a diameter much smaller than that of the toothed disc 45 , so when the mold stops rotating, the coil spring 38 can be locked by utilizing the resistance of the mold itself, which is relatively simple and convenient;

[0054] A transmission member 53 is provided on the mounting frame 35 to move and reset the slide tube 42, and at the same time the coil spring 38 is reset. The transmission member 53 and the drive motor 32 are used to drive the shaft 2 to rotate, so that the drive motor 32 does not need to work under high load, thereby improving the service life of the device.

[0055] The transmission member 53 includes a sprocket plate 54 connected to the hollow shaft 4 39, and a reversing sprocket plate 55 meshing with the sprocket plate 54 is rotatably connected to the mounting frame 35 via a rotating shaft, and a one-way ratchet and ratchet assembly 56 is provided between the sprocket plate 54 and the hollow shaft 4 39. When the hollow shaft 4 39 rotates, the ratchet and ratchet assembly drives the sprocket plate 54 to rotate, thereby driving the reversing sprocket plate 55 to rotate, and then driving the sprocket plate 1 31 to rotate, moving the reset slide tube 42, and driving the reversing sprocket plate 55 to mesh with the sprocket plate 1 31.

[0056] Sprocket five 54 is designed to be the same size as sprocket three 44, and sprocket one 31 is designed to have a diameter much larger than that of sprocket five 54. Therefore, when the reversing sprocket 55 is meshed with sprocket one 31, sprocket three 44 and sprocket four 45 are disengaged, thereby automatically releasing the locking state of the disc spring 38. At the same time, the disc spring 38 will be suddenly released, thereby increasing the power for the mold to start rotating, thereby reducing the compliance of the drive motor 32.

[0057] The base 1 is rotatably connected with a shaft 6 57, a synchronous pulley 58 is fixedly connected to the shaft 6 57, and a synchronous pulley 58 is also fixedly connected to the shaft 1 2. The two synchronous pulleys 58 are connected by a synchronous belt. A toothed disc 6 59 is fixedly connected to the shaft 6 57, and the toothed disc 6 59 is designed to have a smaller diameter than the toothed disc 1 31. Therefore, when the coil spring 38 drives the mold to rotate alone, its force application time is extended;

[0058] A locking assembly 61 is provided on the support frame 43. The sliding tube 42 is moved to drive the gear disc three 44 to engage with the gear disc four 45, and then the sliding tube 42 is continued to be moved to drive the reversing gear disc 55 to engage with the gear disc six 59. At the same time, the locking assembly 61 is used to lock the support frame 43, and the rear disc spring 38 is reset to drive the shaft 2 to rotate alone.

[0059] The locking assembly 61 includes a cylinder 62 rotatably connected to the mounting frame 35 via a bearing, a rotating disk 63 is rotatably connected to the cylinder 62, an arc-shaped clamping block 64 with an L-shaped cross section is fixedly connected to one side of the rotating disk 63, an L-shaped rod 65 is fixedly connected to the support frame 43, a bayonet 66 is slidably connected to one end of the L-shaped rod 65, and the bayonet 66 is located inside the L-shaped rod 65 and fixedly connected to one end of a spring 67, one end of the spring 67 is fixedly connected to the inner wall of the L-shaped rod 65, and one end of the bayonet 66 adopts an arc surface design;

[0060] One end of the slide tube 42 is fixedly connected with a spring 2 68, which is sleeved on the slide rod 41. The slide tube 42 is moved to insert the bayonet 66 into the arc-shaped block 64. At the same time, the spring 2 68 is compressed and contracted to provide self-restoring ability. A torsion spring 69 is sleeved on the cylinder 62. The two ends of the torsion spring 69 are respectively fixedly connected to the rotating disk 63 and the mounting frame 35. The rotating disk 63 is rotated to disengage the bayonet 66 from the arc-shaped block 64. At the same time, the torsion spring 69 is twisted to provide self-restoring ability.

[0061] One end of the cylinder 62 is fixedly connected to a toothed disc 71, and the mounting frame 35 is also rotatably connected to the toothed disc 71 via a rotating shaft. The two toothed discs 71 are meshed, and a plurality of tooth grooves 72 meshing with the toothed disc 71 are evenly and equidistantly provided in the rotating disc 63. The rotating cylinder 62 drives the toothed disc 71 to rotate, thereby driving the rotating disc 63 to rotate.

[0062] A hexagonal column 73 is fixedly connected to one end of the hollow shaft 39, and a hexagonal groove 74 is opened at one end of the cylindrical body 62. The sliding tube 42 is moved to drive the hexagonal column 73 to move and insert into the hexagonal groove 74;

[0063] When in use, after the mold stops rotating, the slide tube 42 is continuously pushed, and the gear disc three 44 is disengaged from the gear disc four 45, and the reversing gear disc 55 is engaged with the gear disc six 59. At the same time, the latch pin 66 is inserted into the arc block 64, and the hexagonal column 73 is also inserted into the hexagonal groove 74. At this time, the disc spring 38 resets and drives the mold to rotate. At the same time, the rotation of the hexagonal column 73 drives the cylinder 62 to rotate, so that the gear disc seven 71 drives the rotating disk 63 to rotate, and at the same time drives the arc block 64 to rotate, so that the arc block 64 automatically unlocks the latch pin 66, and then the spring two 68 is reset to drive the slide tube 42 to reset, so that the gear disc three 44 and the gear disc four 45 are re-engaged to recover the mold rotation energy, so that the energy of the disc spring 38 can be released in multiple stages to drive the mold to rotate alone, and cooperate with the staff to clean or spray the mold, which is more practical.

[0064] Example 2: Please refer to Figure 1-Figure 10 , the present invention provides a technical solution: Example 2 is optimized on the basis of Example 1;

[0065] A positioning magnet 75 is fixedly connected to one end of the slide tube 42, and two positioning magnets 75 are also fixedly connected to the mounting frame 35. The corresponding positioning magnets 75 are adsorbed to temporarily fix the slide tube 42 in two states. One state is that the gear disc three 34 is engaged with the gear disc four 45, and the other state is that the gear disc one 31 is engaged with the gear disc two 34, so that the device body is more stable when in use.
