Description

Technical Field

[0001] This utility model relates to the field of brake disc casting technology, specifically to an automatic pouring mechanism for brake disc casting. Background Technology

[0002] Brakes include disc brakes, drum brakes, and air brakes. Many older cars have front disc brakes and rear drum brakes. Many cars have disc brakes both front and rear because disc brakes dissipate heat better than drum brakes. Under high-speed braking conditions, they are less prone to heat fade, so their high-speed braking effect is better. However, at low speeds and when cold, their braking effect is not as good as drum brakes. Disc brakes are also more expensive than drum brakes. Therefore, many mid-to-high-end cars use all disc brakes, while ordinary cars use front disc brakes and rear drum brakes. Trucks and buses, which require relatively low speeds and high braking force, still use drum brakes. During the production and processing of brake discs, a casting process is required, which is called casting, to form the brake discs.

[0003] In the prior art, a brake disc casting pouring mechanism with publication number CN219724572U includes a frame, a reciprocating screw rotatably connected to the upper inner side of the frame, and a drive motor fixedly connected to one side of the outer wall of the frame by bolts. One end of the reciprocating screw passes through the side wall of the frame and is connected to the output shaft of the drive motor for transmission. A nut seat is threadedly connected to one end of the reciprocating screw. The method proposed in this utility model facilitates the control of the pouring volume of the brake disc mold through the bearing cylinder. At the same time, by utilizing the movement of the bearing cylinder, multiple brake disc molds can be poured.

[0004] However, while the aforementioned application allows for the pouring of multiple brake discs, the recovery of dripping material from the pouring head is not very effective. Furthermore, the pouring head's ability to scrape and recover impurities from its surface is limited after prolonged use, resulting in a higher level of impurities on the head surface. This negatively impacts the cleanliness of subsequent brake disc pouring. Additionally, the tilting of the carrier box is often done manually, leading to inconsistent precision in controlling the tilt angle and resulting in either excessive or insufficient pouring of material, thus affecting the quality of the brake disc pouring.

[0005] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed an automatic pouring mechanism for brake disc casting. Utility Model Content

[0006] The purpose of this utility model is to provide an automatic pouring mechanism for brake disc casting, so as to solve the problems mentioned in the background art, such as the low efficiency of raw material recovery from dripping on the surface of the pouring head, the low efficiency of scraping and recovering impurities on the surface of the pouring head after long-term use, and the low precision of automatic tilting angle control of the bearing box.

A recycling box is slidably connected to the inner side wall of the recycling frame.

[0009] Preferably, a second motor is fixedly connected to the outer wall of the threaded slide plate, and a rotating shaft is fixedly connected to the output end of the second motor. A scraper is detachably connected to the outer wall of the rotating shaft, and a nut is provided on the outer wall of the scraper. A bolt that is slidably connected to the outer wall of the rotating shaft is threaded to the inner wall of the nut. A groove is provided at the connection between the outer wall of the rotating shaft and the bolt.

[0010] Furthermore, a third motor is fixedly connected to the outer wall of the sliding block, and a second threaded rod that is rotatably connected to the outer wall of the sliding block is fixedly connected to the output end of the third motor. A threaded slider that is slidably connected to the outer wall of the sliding block is threadedly connected to the outer wall of the second threaded rod. A swing rod that is fixedly connected to the end of the connecting shaft is slidably connected to the outer wall of the threaded slider. A limit groove is provided at the connection part between the outer wall of the swing rod and the threaded slider. A pointer is fixedly connected to the end of the connecting shaft away from the swing rod. A protractor located on one side of the pointer is fixedly connected to the outer wall of the sliding block.

[0011] Furthermore, a flow port is provided at the connection between the outer wall of the carrier box and the pouring head, the threaded slide plate forms a sliding structure with the carrier box through the first threaded rod, and a connecting groove is provided at the connection between the bottom of the carrier box and the threaded slide plate.

[0012] Furthermore, the recycling port extends out from a position directly below the pouring head, and the scraper is in a horizontally retracted state when extended.

[0013] Furthermore, the scraper forms an oscillating structure between the second motor and the rotating shaft, and the scraper is set to be in close contact with the surface of the pouring head in the use state.

[0014] Furthermore, the scraper is engaged with the rotating shaft by bolts and slots. There are two sets of bolts and slots, and the positions of the two sets of bolts and slots are symmetrical about the central axis of the scraper.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model, through the setting of a recycling box and a scraper, improves the convenience of recycling raw material dripping from the surface of the pouring head and the effect of simultaneously scraping and cleaning the impurities adsorbed on the surface of the pouring head when the brake disc is processed by the auxiliary forging equipment of the pouring mechanism. The first motor can be turned on to drive the threaded slide plate to extend along the bottom of the bearing box through the rotation of the first threaded rod, so that the recycling port moves to the bottom of the pouring head, preventing raw material from dripping into the pouring bottom frame and affecting the cleanliness of the subsequent brake disc surface processing. The second motor can be turned on to drive the scraper to swing back and forth along the surface of the pouring head through the rotation of the shaft, so as to achieve the effect of convenient cleaning and recycling of impurities adsorbed on the pouring head.

[0019] 2. By setting up a slot, this utility model allows for the cleaning of the surface of the pouring head by the scraper over a long period of time. In order to improve the cleanliness of the scraper surface after long-term use, the bolt can be rotated periodically and the nut can be used to limit the movement of the bolt, allowing it to slide out from the inner wall of the slot and the scraper to be disassembled from the outer wall of the rotating shaft. This achieves the effect of convenient disassembly and replacement of the scraper after long-term use.

[0020] 3. This utility model, through the setting of a pointer and a protractor, when forging and pouring through the carrier box and pouring head, in order to improve the automation of the carrier box tilt angle and the precision control of the carrier box angle adjustment degree, can turn on the third motor and drive the second threaded rod to rotate, thereby driving the threaded slider to slide along the outer wall of the sliding block. At the same time, it drives the threaded slider to slide along the inner wall of the limiting groove. The sliding of the threaded slider, through the connection of the connecting shaft, drives the swing rod to perform angle adjustment movement and drives the connecting shaft to perform synchronous rotation movement. Under the action of the protractor, the rotation of the connecting shaft plays the role of accurately observing and controlling the pointer rotation degree. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1:

[0031] like Figures 1-6As shown, an automatic pouring mechanism for brake disc casting includes a pouring equipment frame 1. A pouring base frame 2 is provided on the outer wall of the pouring equipment frame 1. A positioning arc-shaped rod 3 is provided on the inner side wall of the pouring base frame 2. A fixing rod 4 is fixedly connected to the inner side wall of the pouring equipment frame 1. A sliding block 5 is slidably connected to the outer wall of the fixing rod 4. A connecting shaft 6 is rotatably connected to the outer wall of the sliding block 5. A bearing box 7 located on the inner side wall of the sliding block 5 is fixedly connected to the end of the connecting shaft 6. A pouring head 8 is fixedly connected to the outer wall of the bearing box 7. A first motor 9 is fixedly connected to the bottom of the bearing box 7. A first threaded rod 10 rotatably connected to the bottom of the bearing box 7 is fixedly connected to the output end of the first motor 9. The outer wall is threaded with a threaded slide plate 11 that is slidably connected to the bottom of the carrier box 7. The end of the threaded slide plate 11 is fixedly connected to a recycling frame 12. The outer wall of the threaded slide plate 11 has a recycling port 13 located above the recycling frame 12. The inner side wall of the recycling frame 12 is slidably connected to a recycling box 14. The outer wall of the threaded slide plate 11 is fixedly connected to a second motor 15. The output end of the second motor 15 is fixedly connected to a rotating shaft 16. The outer wall of the rotating shaft 16 is detachably connected to a scraper 17. The outer wall of the scraper 17 is provided with a nut 27. The inner wall of the nut 27 is threaded with a bolt 18 that is slidably connected to the outer wall of the rotating shaft 16. The connection part between the outer wall of the rotating shaft 16 and the bolt 18 is provided with a slot 19.

[0032] like Figure 5 As shown, a flow port is provided at the connection between the outer wall of the carrier box 7 and the pouring head 8. The threaded slide plate 11 forms a sliding structure with the carrier box 7 through the first threaded rod 10. A connecting groove is provided at the connection between the bottom of the carrier box 7 and the threaded slide plate 11, which is conducive to the rotation of the first threaded rod 10 and drives the threaded slide plate 11 to move in and out along the bottom of the carrier box 7, so as to facilitate the switching of the use status of the scraper 17 and the recycling box 14.

[0033] like Figure 5 As shown, the recycling port 13 extends out and is positioned directly below the pouring head 8. The scraper 17 is in a horizontally retracted state when extended. This arrangement of the recycling port 13 extending out and being positioned directly below the pouring head 8 facilitates the convenient recycling of raw materials dripping from the surface of the pouring head 8.

[0034] like Figure 5 and Figure 6 As shown, the scraper 17 forms an oscillating structure with the second motor 15 and the rotating shaft 16. When in use, the scraper 17 is set to be in close contact with the surface of the pouring head 8, which is conducive to the second motor 15 driving the scraper 17 to swing back and forth through the connection of the rotating shaft 16, so as to achieve the effect of conveniently scraping and cleaning the impurities adsorbed on the surface of the pouring head 8.

[0035] like Figure 6As shown, the scraper 17 forms an engaging structure with the rotating shaft 16 through bolts 18 and slots 19. There are two sets of bolts 18 and slots 19. The positions of the two sets of bolts 18 and slots 19 are symmetrical about the central axis of the scraper 17, which facilitates the sliding of the bolts 18 along the inner wall of the slots 19 and drives the scraper 17 to engage and disengage along the outer wall of the rotating shaft 16, thereby improving the cleanliness of the scraper 17 during long-term use.

[0036] Example 2:

[0037] like Figure 1 , Figure 2 and Figure 4 As shown, the automatic pouring mechanism for brake disc casting proposed in this utility model, compared with Embodiment 1, is another embodiment of this utility model. A third motor 20 is fixedly connected to the outer wall of the sliding block 5. A second threaded rod 21, rotatably connected to the outer wall of the sliding block 5, is fixedly connected to the output end of the third motor 20. A threaded slider 22, slidably connected to the outer wall of the sliding block 5, is threadedly connected to the outer wall of the second threaded rod 21. A swing rod 23, fixedly connected to the end of the connecting shaft 6, is slidably connected to the outer wall of the threaded slider 22. A limit groove 24 is provided at the connection between the outer wall of the swing rod 23 and the threaded slider 22. A pointer 25 is fixedly connected to the end of the connecting shaft 6 away from the swing rod 23. A pointer 25 is fixedly connected to the outer wall of the sliding block 5 at the position of the pointer 25. The protractor 26 on the side, when in operation, by setting the pointer 25 and the protractor 26, is beneficial to improve the automation of the tilt angle of the carrier box 7 and the accuracy of the angle adjustment of the carrier box 7 when forging and pouring through the pouring head 8. The third motor 20 can be turned on to drive the threaded slider 22 to slide along the outer wall of the sliding block 5 through the rotation of the second threaded rod 21. At the same time, the threaded slider 22 is driven to slide along the inner wall of the limiting groove 24. The sliding of the threaded slider 22 is connected through the connecting shaft 6, which drives the swing rod 23 to perform angle adjustment movement and drives the connecting shaft 6 to perform synchronous rotation movement. The rotation of the connecting shaft 6, under the action of the protractor 26, plays the role of accurately observing and controlling the rotation degree of the pointer 25.

[0038] like Figure 4 As shown, the threaded slider 22 forms a sliding structure with the sliding block 5 through the second threaded rod 21. The rotation center of the swing rod 23 and the rotation center of the connecting shaft 6 are on the same horizontal plane, which is conducive to the rotation of the second threaded rod 21, and drives the threaded slider 22 to slide along the outer wall of the sliding block 5, thereby facilitating the rotation of the swing rod 23.

[0039] like Figure 3As shown, the pointer 25 forms an oscillating structure with the sliding block 5 through the swing rod 23 and the connecting shaft 6. The protractor 26 is located on the indicating trajectory of the pointer 25, which is conducive to the rotation of the swing rod 23. Through the connection of the connecting shaft 6, the pointer 25 is driven to rotate synchronously along the outer wall of the sliding block 5, which plays the role of accurately observing and controlling the rotation degree of the pointer 25.

[0040] Working principle:

[0041] First, when the brake disc is processed by the auxiliary forging equipment of the pouring mechanism, in order to improve the convenience of recovering the raw material dripping from the surface of the pouring head 8 and the effect of simultaneously scraping, cleaning and recovering the impurities adsorbed on the surface of the pouring head 8, the first motor 9 can be turned on and the first threaded rod 10 can be rotated to drive the threaded slide plate 11 to extend along the bottom of the bearing box 7, so that the recovery port 13 moves to the bottom of the pouring head 8, preventing the raw material from dripping into the pouring bottom frame 2 and affecting the cleanliness of the subsequent brake disc surface processing. The second motor 15 can be turned on and the rotating shaft 16 can be rotated to drive the scraper 17 to swing back and forth along the surface of the pouring head 8 to clean, so as to achieve the effect of convenient cleaning and recovery of the impurities adsorbed on the pouring head 8.

[0042] Secondly, when cleaning the surface of the pouring head 8 with the scraper 17 for a long time, in order to improve the cleanliness of the scraper 17 after long-term use, the bolt 18 can be rotated periodically and the nut 27 can be used to limit the bolt 18 to slide out from the inner wall of the slot 19 and remove the scraper 17 from the outer wall of the rotating shaft 16, so as to achieve the effect of convenient disassembly and replacement of the scraper 17 after long-term use.

[0043] Finally, when forging and pouring are carried out through the support box 7 and the pouring head 8, in order to improve the automation of the tilt angle of the support box 7 and the precision control of the angle adjustment degree of the support box 7, the third motor 20 can be turned on. Through the rotation of the second threaded rod 21, the threaded slider 22 is driven to slide along the outer wall of the sliding block 5. At the same time, the threaded slider 22 is driven to slide along the inner wall of the limiting groove 24. The sliding of the threaded slider 22 is connected through the connecting shaft 6, which drives the swing rod 23 to perform angle adjustment movement and drives the connecting shaft 6 to perform synchronous rotation movement. The rotation of the connecting shaft 6, under the action of the protractor 26, plays the role of accurately observing and controlling the rotation degree of the pointer 25.
