[0002] As the core component of the automotive braking system, the quality of the brake disc is directly related to driving safety. The casting quality of the brake disc is closely related to the forming accuracy of the sand mold. The molding machine is a key piece of equipment used to manufacture sand molds in casting production.

[0003] Currently available brake disc molding machines still have the following problems:

[0004] Some brake disc molding machines cannot accurately control the amount of sand fed into the mold, resulting in either too much or too little sand being fed. This can affect the dimensional accuracy and compactness of the sand mold, making it difficult to maintain stable quality control in brake disc casting. Consequently, it can lead to sand waste, mold defects, or a lower yield rate of finished brake discs. Utility Model Content

[0027] Reference Figure 1-4This utility model discloses a special molding machine for brake discs, including a worktable 1. A support frame 2 is fixedly installed on the upper end of the worktable 1. A slide groove 16 is opened on one side of the support frame 2. A cylinder 8 is fixedly installed on the upper end of the support frame 2. An extension end of the cylinder 8 passes through the support frame 2 and is fixedly installed downwards on a mounting plate 17. The mounting plate 17 is slidably installed in the slide groove 16. A mounting box 3 is fixedly installed on the upper end of the mounting plate 17. A metering component is provided in the mounting box 3. The metering component includes a fixing block 19, a pressure sensor 18, a metering hopper 22, a discharge pipe 20, and a solenoid valve 23. Two fixing blocks 19 are fixedly installed on both sides of the middle part of the mounting box 3. Two pressure sensors 18 are symmetrically arranged on the upper end of each fixing block 19. A metering hopper is arranged on the upper end of each pressure sensor 18. 22. A discharge pipe 20 is provided at the bottom center of the metering hopper 22. A solenoid valve 23 is provided on the discharge pipe 20. The ends of the discharge pipe 20 pass through the mounting box 3 and the mounting plate 17 downwards. In use, the sliding groove 16 in the support frame 2 provides precise sliding guidance for the mounting plate 17. With the cylinder 8 fixed at its upper end, the mounting plate 17 can be driven to move the mounting box 3 flexibly. The fixing block 19 in the mounting box 3 provides reliable support for the pressure sensor 18. The pressure sensor 18 accurately weighs the metering hopper 22 and the material inside. Combined with the solenoid valve 23 on the discharge pipe 20, the quantitative control of the material is realized, which effectively reduces waste and ensures the quality of sand molding. It avoids the sand overflow waste caused by excessive sand or the sand molding quality being affected by insufficient sand, which would cause defects in the brake disc casting.

[0028] Two fixing plates 9 are fixedly installed on the support frame 2 at the front end of cylinder 8. A feeding hopper 5 is fixedly installed on the two fixing plates 9. A motor 27 is fixedly installed on one side of the feeding hopper 5. The output end of the motor 27 passes through the feeding hopper 5 and is connected to a screw conveyor rod 28 via a coupling. A feed pipe 6 is fixedly installed at the upper end of the feeding hopper 5, and a feed hopper 7 is fixedly installed at the other end of the feed pipe 6. A feed pipe 11 is provided at one bottom end of the feeding hopper 5, and a solenoid valve 10 is installed on the feed pipe 11. A conveying pipe 21 is provided in the middle of the upper end of the mounting box 3, and a flexible telescopic hose is provided between the conveying pipe 21 and the feed pipe 11. 4. During use, the two fixed plates 9 on the support frame 2 provide stable installation support for the conveying bin 5, ensuring its operational stability. The feeding hopper 7 connected to the upper end of the conveying bin 5 via the feeding pipe 6 can achieve efficient material collection. The side motor 27 drives the spiral conveying rod 28 to rotate, which can push the material to the conveying pipe 11 in a directional and precise manner. The solenoid valve 10 on the conveying pipe 11 can flexibly control the start and stop of the material supply. With the telescopic hose 4 between the conveying pipe 11 and the upper conveying pipe 21 of the mounting box 3, it can not only adapt to the displacement requirements of the mounting box 3, but also avoid the leakage of materials during the conveying process, thus achieving stable and controllable material conveying as a whole.

[0029] A cylinder 212 is fixedly installed at one bottom end of the support frame 2. An upper mold core 13 is fixedly installed on the extension of cylinder 212. A cylinder 314 is fixedly installed on one side of the support frame 2. A lower module 15 is fixedly installed on the extension of cylinder 314. A mold hole 24 is opened on the lower module 15. A cylinder 426 is fixedly installed inside the lower module 15. A lower mold core 25 is fixedly installed on the extension of cylinder 426. Both the lower mold core 25 and the upper mold core 13 are adapted to the mold hole 24. In use, cylinder 212 at one bottom end of the support frame 2 can drive the upper mold core 13. The mold core 13 is precisely positioned close to the mold hole 24. In conjunction with the cylinder 3 14 on one side of the support frame 2, the lower module 15 is pushed to adjust its position, ensuring that the upper mold core 13 and the mold hole 24 of the lower module 15 are precisely aligned. This provides stable pressure and precise positioning for material pressing and molding. The cylinder 4 26 inside the lower module 15 can drive the lower mold core 25 to move upward. The lower mold core 25, which is compatible with the mold hole 24, is used to smoothly push out the molded sand mold, avoiding damage to the sand mold during demolding and greatly improving the finished product qualification rate. The whole process achieves efficient and stable connection between brake disc sand mold forming and demolding.

[0030] Working Principle: When a brake disc molding machine is put into use, the material first enters the conveying bin 5 through the feeding hopper 7 and feeding pipe 6. The motor 27 on one side of the conveying bin 5 is started, and its output end drives the screw conveyor 28 to rotate via a coupling, pushing the material towards the conveying pipe 11. The solenoid valve 10 on the conveying pipe 11 is opened, and the material enters the metering hopper 22 inside the mounting box 3 through the telescopic hose 4 and conveying pipe 21. The metering hopper 22 is supported by pressure sensors 18 on the upper ends of the fixing blocks 19 on both sides of the middle of the mounting box 3. The pressure sensors 18 detect the weight of the material in the metering hopper 22 in real time, achieving accurate metering. After metering is completed, the cylinder 8 on the upper end of the support frame 2 is started, and its extension end pushes the mounting plate 17 along... The slide 16 slides downward, causing the mounting box 3 to move down to the appropriate position. Then, the solenoid valve 23 on the discharge pipe 20 is opened, and the material falls into the mold hole 24 of the lower module 15 through the discharge pipe 20. Then, the cylinder 12 at one end of the bottom of the support frame 2 is activated, and its extension pushes the upper mold core 13 close to the mold hole 24. At the same time, the cylinder 14 on one side of the support frame 2 is activated, and its extension pushes the lower module 15 to adjust its position so that the mold hole 24 is aligned with the upper mold core 13, so that the upper mold core 13 presses the material in the mold hole 24 into shape. After pressing, the cylinder 26 in the lower module 15 is activated, and its extension pushes the lower mold core 25 upward to push out the pressed mold, thus completing the production of the brake disc sand mold.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
