DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 to Figure 4In an embodiment of the utility model, a brake disc casting device comprises a lower casting mold 1 and an upper casting mold 2, the upper casting mold 2 is located at the top of the lower casting mold 1, the top of the lower casting mold 1 is provided with a liquid inlet 3 connected to the inner cavity of the upper casting mold 2, and the top of the lower casting mold 1 is also provided with an exhaust port 4 connected to the inner cavity of the upper casting mold 2, a synchronous driving mechanism is installed at the bottom of the lower casting mold 1, and a clamping mechanism extending to the top of the upper casting mold 2 is provided on the outer periphery of the lower casting mold 1; the synchronous driving mechanism is used to drive a plurality of clamping mechanisms equidistantly distributed circumferentially to simultaneously press down and limit the top of the upper casting mold 2, or synchronously drive a plurality of clamping mechanisms equidistantly distributed circumferentially to simultaneously release the downward pressure limit on the top of the upper casting mold 2.

[0021] In this embodiment: during casting, first, the synchronous drive mechanism is started, and the synchronous drive mechanism drives the clamping mechanism to effectively clamp the upper casting mold 2, and then the liquid molten iron is introduced into the upper casting mold 1 and the lower casting mold 2 through the liquid inlet 3. During the process of the molten iron entering, the gas in the casting mold is discharged through the exhaust port 4. After the casting is completed, the synchronous drive mechanism is started in reverse again to release the limit of the clamping mechanism on the upper casting mold 2. This method achieves the effect of quickly limiting or releasing the limit of the mold.

[0022] Please refer to Figure 3 and Figure 4 The synchronous drive mechanism includes a forward and reverse motor 14, the output end of the forward and reverse motor 14 is connected to a driving gear 12, and the outer periphery of the driving gear 12 is meshed with a plurality of driven gears 8 of equal size, and the plurality of driven gears 8 are equidistantly distributed in the circumferential direction.

[0023] In this embodiment: by starting the forward and reverse motor 14, the forward and reverse motor 14 drives the driving gear 12 to rotate, and the rotating driving gear 12 drives the multiple driven gears 8 distributed on its periphery to rotate synchronously. Since the rotation directions of the multiple driven gears 8 are opposite to the rotation direction of the driving gear 12, the rotation directions of the multiple driven gears 8 are consistent.

[0024] Please refer to Figure 1 , Figure 2 and Figure 3 A downwardly extending column 9 is welded to the bottom end of the lower casting mold 1, and a mounting bracket 13 is fixedly connected to the outer walls of the two columns 9. A forward and reverse motor 14 is fixedly connected to the bottom end of the circular plate portion at the center of the mounting bracket 13, and the output shaft of the forward and reverse motor 14 is rotatably connected to the circular plate portion through a bearing.

[0025] In this embodiment: the mounting bracket 13 fixes the position of the forward and reverse motor 14 to provide support for the forward and reverse motor 14 . When the forward and reverse motor 14 rotates, the bearing can effectively reduce the friction between the output shaft of the forward and reverse motor 14 and the mounting bracket 13 .

[0026] Please refer to Figure 1 and Figure 2 and Figure 3 The clamping mechanism includes a plurality of fixed blocks 5 which are circumferentially arranged and equidistantly distributed. The inner wall of the fixed block 5 is rotatably connected with a rotating shaft 7. The bottom end of the rotating shaft 7 is fixedly connected with the top of the driven gear 8. The top of the rotating shaft 7 passes through the top of the fixed block 5, and the top of the rotating shaft 7 is fixedly connected with a rotating pressure plate 6.

[0027] In this embodiment, when the plurality of driven gears 8 rotate synchronously in the same direction, the driven gears 8 drive the rotating shaft 7 on the top thereof to rotate, and the rotation of the rotating shaft 7 drives the rotating pressure plate 6 to rotate.

[0028] Please refer to Figure 1 and Figure 2 The clamping mechanism also includes a plurality of triangular blocks 10 integrally formed on the top of the upper casting mold 2. The plurality of triangular blocks 10 are equidistantly distributed circumferentially. The top of the triangular block 10 and the bottom of the rotating pressing plate 6 are both formed with extrusion slopes 11, and the two extrusion slopes 11 are consistent with each other.

[0029] In this embodiment: when the rotating pressing plate 6 rotates to gradually overlap with the triangular block 10, the extrusion slope 11 at the bottom end of the rotating pressing plate 6 gradually overlaps with the extrusion slope 11 at the top of the triangular block 10 until the two overlap in the up and down directions. At this time, the rotating pressing plate 6 continues to rotate, and the two extrusion slopes 11 squeeze each other during rotation. The extrusion force is applied to the top of the upper casting mold 2, thereby forming an effective upper limit force on the upper casting mold 2, avoiding the problem of the upper casting mold 2 being pushed upward due to the increase in temperature and internal pressure during the pouring of molten iron.

[0030] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
