[0002] Precision casting molds for gradient cooling of brake components are a special type of mold used to produce high-precision brake components. Brake system components usually need to withstand high temperature and high pressure working environments, so they are required to have excellent wear resistance, thermal stability and corrosion resistance.

Support columns are fixedly connected to the upper surface of the base plate in a rectangular arrangement. A mold container is fixedly connected to the upper surface of the support columns. Lifting rods are slidably connected to the lower end of the mold container in a rectangular arrangement. A lifting plate is fixedly connected to the lower end of the lifting rods. A pulley is slidably connected to the rear side of the upper surface of the base plate via a sliding groove. A movable plate is provided on the upper end of the pulley. A dust collection box is fixedly connected to the upper surface of the movable plate. An exhaust fan is connected to the upper end of the dust collection box. A suction pipe is connected to the air inlet of the exhaust fan. The upper end of the suction pipe... With a dust extraction head, this utility model facilitates the removal of parts from the mold container after stamping and can also suck up the debris generated during stamping, preventing debris from flying and polluting the environment. However, it still has the following shortcomings: the mold of this device does not have the function of easy disassembly and assembly, so it is not convenient to replace the mold by disassembly and assembly. In the case of small batch and multi-variety production, it will cause production line stoppage, increase the production changeover time, and thus affect production efficiency. Therefore, we propose a gradient cooling precision casting mold for brake components. Utility Model Content

A hydraulic rod is provided, with a second fixing plate fixedly connected to its end. The second fixing plate has two through slots, each slot containing a rod. The lower end of the rod is fixedly connected to the upper mold. The second fixing plate also has a first sliding groove, in which two clamping blocks are slidably connected. The bottom of each clamping block is provided with a first slider that matches the first sliding groove. Each clamping block is threadedly connected to a bidirectional threaded rod. A second slider is provided on one side of the second fixing plate. A third fixing plate is installed on the top surface of the housing, with a second sliding groove on the third fixing plate, in which the second slider is assembled.

[0005] Furthermore, in the aforementioned precision casting mold for gradient cooling of brake components, the first groove is disposed between the two slots and the direction of the first groove is perpendicular to the line connecting the two slots, and the two clamping blocks are respectively located on both sides of the slots.

[0006] Furthermore, in the aforementioned precision casting mold for gradient cooling of brake components, the top surface of the upper mold is provided with a liquid injection hole, and the top surface of the second fixed plate is provided with a liquid injection port, the liquid injection port being matched with and connected to the liquid injection hole.

[0007] Furthermore, in the aforementioned precision casting mold for gradient cooling of brake components, the mold closing mechanism includes two fixed shafts disposed on opposite sides of the second fixed plate (without the second slider) and two fixed frames disposed on the top surface of the housing. Each fixed frame corresponds to one of the fixed shafts. A vertical third slide groove is formed within the two side bosses of each fixed frame. The two protruding ends of the T-shaped third slider are slidably fitted into the two third slide grooves. A first telescopic rod is fixedly connected to the lower part of each of the two protruding ends of the third slider. The lower end of the first telescopic rod is fixed to the fixed frame. A first spring is fitted around the outer periphery of each first telescopic rod. The upper end of the spring is fixedly connected to the two protruding ends of the third slider, and the lower end of the first spring is fixedly connected to the fixed frame. A fourth slide groove is provided in the middle of the third slider. A fourth slider and a second telescopic rod are installed in the fourth slide groove. The fourth slider is slidably assembled in the fourth slide groove. The two ends of the second telescopic rod are respectively fixedly connected to one side of the fourth slider and the inner wall of the fourth slide groove. A second spring is fitted around the outer periphery of the second telescopic rod. The two ends of the second spring are respectively fixedly connected to one side of the fourth slider and the inner wall of the fourth slide groove. A locking block is fixedly connected to the top surface of the fourth slider. The locking block has a through hole that matches the fixed shaft.

[0008] Furthermore, in the aforementioned precision casting mold for gradient cooling of brake components, the mold closing mechanism further includes an air-cooling device disposed within the housing, with the air outlet of the air-cooling device facing the lower mold.

[0009] The gradient cooling precision casting mold for brake components of this utility model has the following advantages and beneficial effects:

[0010] 1. By innovatively incorporating a disassembly mechanism into the precision casting mold for gradient cooling of brake components, when mold replacement is required, rotating the bidirectional threaded rod causes two clamping blocks to slide away from each other in the first groove, thereby releasing the clamping blocks from the insert rod. This allows the insert rod, which is fixedly connected to the upper mold, to be removed from the second fixing plate, and then a new upper mold can be installed. Therefore, the mold of this invention features convenient disassembly and assembly, enabling quick and easy mold replacement. It adapts to the different mold requirements of various brake components. In small-batch, multi-variety production, rapid mold replacement reduces time and labor costs associated with mold adjustment and maintenance, improving production flexibility and efficiency.

[0011] 2. By innovatively setting a mold closing mechanism on the precision casting mold for gradient cooling of braking components, after the upper and lower molds are closed, the third slider moves upward. As the third slider moves in the third slide groove, the first telescopic rod and the first spring are stretched, and then the locking block is pushed outward of the equipment, causing the second spring and the second telescopic rod to retract. This causes the locking block to lock the fixed shaft through its through hole. In this state, due to the elastic restoring force of the first spring, the third slider will be continuously pulled downward, thereby strengthening the mold closing effect of the upper and lower molds, improving the stability and uniformity of the closure of the upper and lower molds, ensuring the safety and reliability of the casting process, and improving product quality and mold service life.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Please see Figure 1-5 As shown, the precision casting mold for gradient cooling of brake components of this utility model includes a housing 101. A support rod 102 is fixed at each of the four corners of the top wall of the housing 101. A first fixing plate 103 is fixedly connected to the top of the four support rods 102. The first fixing plate 103 is provided with a disassembly mechanism 2. A mold closing mechanism 3 is provided on the housing 101. Furthermore, the precision casting mold for gradient cooling of brake components also includes an upper mold 104 and a lower mold 105. The top surface of the upper mold 104 is provided with a liquid injection hole, and the lower mold 105 is mounted on the housing 101.

[0024] The disassembly mechanism 2 includes a hydraulic actuator 201, a hydraulic rod 202, a second fixing plate 203, a slot 204, an insert rod 205, a first sliding groove 206, a clamping block 207, a first slider 208, a bidirectional threaded rod 209, an injection port 210, a second slider 211, a third fixing plate 212, and a second sliding groove 213. The hydraulic actuator 201 is fixed to the top surface of the first fixing plate 103. The lower end of the hydraulic actuator 201 is fixedly connected to the hydraulic rod 202, and the end of the hydraulic rod 202 is fixedly connected to the second fixing plate 203. The hydraulic actuator 201 can drive the hydraulic rod 202 to move up and down. When the hydraulic rod 202 moves, it will drive the second fixing plate 203 to move up and down. Two through slots 204 are provided on the second fixing plate 203. Each slot 204 contains an insert rod 205, and the lower end of the insert rod 205 is fixedly connected to the upper mold 104. The second fixed plate 203 is also provided with a first sliding groove 206, in which two clamping blocks 207 are slidably connected. The first sliding groove 206 is located between two slots 204 and its direction is perpendicular to the line connecting the two slots 204. The two clamping blocks 207 are located on both sides of the slots 204. The bottom of each clamping block 207 is provided with a first slider 208 matching the first sliding groove 206. Each clamping block 207 is threadedly connected with a bidirectional threaded rod 209. When the insert rod 205, which is fixedly connected to the upper mold 104, is inserted into the slot 204 of the second fixed plate 203 from bottom to top, the two clamping blocks 207 are driven to move by rotating the bidirectional threaded rod 209. By sliding close together in the first slide groove 206, the insert rod 205 can be clamped and fixed, thereby fixing the upper mold 104 to the second fixing plate 203. Thus, when the second fixing plate 203 moves up and down under the drive of the hydraulic rod 202, the upper mold 104 moves up and down accordingly, realizing the opening and closing of the mold with the lower mold 105 on the housing 101. Conversely, by rotating the bidirectional threaded rod 209, the two clamping blocks 207 are driven to slide away from each other in the first slide groove 206, thereby causing the clamping blocks 207 to leave the insert rod 205, thus releasing the insert rod 205. This allows the insert rod 205, which is fixedly connected to the upper mold 104, to be removed from the second fixing plate 203 for easy replacement of the upper mold 104.

[0025] The top surface of the second fixing plate 203 is provided with a liquid injection port 210, which is matched and connected to the liquid injection hole on the top surface of the upper mold 104.

[0026] A second slider 211 is provided on one side of the second fixed plate 203. Corresponding to the second slider 211, a third fixed plate 212 is installed on the top surface of the housing 101 between the two support rods 102. A second slide groove 213 is provided on the third fixed plate 212. The second slider 211 is assembled in the second slide groove 213 and can slide up and down in the second slide groove 213. Thus, when the upper mold 104 moves up and down with the second fixed plate 203, the second slider 211 slides vertically along the second slide groove 213 to position and guide the upper mold 104 in the vertical direction, so as to accurately open and close the mold between the upper mold 104 and the lower mold 105.

[0027] The mold clamping mechanism 3 includes two fixed shafts 302 disposed on opposite sides of the second fixed plate 203 where the second slider 211 is not disposed, and two fixed frames 303 disposed on the top surface of the housing 101. The fixed frames 303 correspond one-to-one with the fixed shafts 302. Each of the two protrusions on both sides of the fixed frame 303 has a vertical third slide groove 304. The two protruding ends of the T-shaped third slider 305 are slidably fitted into the two third slide grooves 304 respectively. The lower part of the two protruding ends of the third slider 305 is fixedly connected to a first telescopic rod 306. The lower end of the first telescopic rod 306 is fixed to the fixed frame 303. A first spring 307 is fitted around the outer periphery of each first telescopic rod 306. The upper end of the first spring 307 is fixedly connected to the two protruding ends of the third slider 305, and the lower end of the first spring 307 is fixedly connected to the fixed frame 303.

[0028] The third slider 305 has a fourth slide groove 308 in the middle. The fourth slider 309 and the second telescopic rod 310 are installed in the fourth slide groove 308. The fourth slider 309 is slidably assembled in the fourth slide groove 308. The two ends of the second telescopic rod 310 are respectively fixedly connected to one side of the fourth slider 309 and the inner wall of the fourth slide groove 308. The outer periphery of the second telescopic rod 310 is fitted with a second spring 311. The two ends of the second spring 311 are respectively fixedly connected to one side of the fourth slider 309 and the inner wall of the fourth slide groove 308. The top surface of the fourth slider 309 is fixedly connected with a locking block 312. The locking block 312 has a through hole that matches the fixed shaft 302.

[0029] The mold closing mechanism 3 may also include an air cooling device 301 disposed in the housing 101. The air outlet of the air cooling device 301 faces the lower mold 105 disposed on the housing 101. By using the air cooling device 301, the molten metal / casting in the upper mold 104 and the lower mold 105 can be cooled during casting, ensuring uniform cooling of the casting and casting quality, and avoiding casting defects caused by local overheating or overcooling.

[0030] The working principle and process of the gradient cooling precision casting mold for brake components of this utility model are briefly described as follows:

[0031] When it is necessary to change the mold, rotate the bidirectional threaded rod 209 to drive the two clamping blocks 207 to slide away from each other in the first slide groove 206, thereby disengaging the clamping blocks 207 from the insert rod 205 and releasing the insert rod 205. This allows the insert rod 205, which is fixedly connected to the upper mold 104, to be removed from the second fixed plate 203. Then, replace the upper mold 104 with a new one. Insert the insert rod 205, which is fixedly connected to the new upper mold 104, into the slot 204 of the second fixed plate 203 from bottom to top. Rotate the bidirectional threaded rod 209 to drive the two clamping blocks 207 to slide closer to each other in the first slide groove 206, clamping and fixing the insert rod 205, thereby fixing the upper mold 104 to the second fixed plate 203. Then, the second fixed plate 203 can be driven to move downward by the hydraulic rod 202, causing the upper mold 104 to move downward as well, realizing the mold closing of the upper mold 104 and the lower mold 105, and carrying out the casting production.

[0032] During the movement of the upper mold 104 with the second fixed plate 203, the second slider 211 always slides vertically along the second slide groove 213, thereby positioning and guiding the upper mold 104 in the vertical direction, thus ensuring the precise opening and closing of the upper mold 104 and the lower mold 105.

[0033] Furthermore, after the upper mold 104 and the lower mold 105 are closed, the third slider 305 moves upward. As the third slider 305 moves in the third slide groove 304, the first telescopic rod 306 and the first spring 307 are stretched. Then, the locking block 312 is pushed outward, causing the second spring 311 and the second telescopic rod 310 to retract. By adjusting the position of the locking block 312 using the above method, the locking block 312 is aligned with the fixed shaft 302 and then released. Under the action of the elastic restoring force of the second spring 311, it is pushed... The fourth slider 309 moves, thereby driving the locking block 312 to move, which in turn causes the locking block 312 to lock the fixed shaft 302 through its through hole. In this state, due to the elastic restoring force of the first spring 307, the third slider 305 will be continuously pulled downward, so that the fixed shaft 302 will be continuously subjected to downward pulling force. This strengthens the mold closing effect of the upper mold 104 and the lower mold 105, improves the stability and uniformity of the closure of the upper and lower molds, ensures the safety and reliability of the casting process, and improves product quality and mold service life.

[0034] Furthermore, during the casting of the brake components within the upper mold 104 and lower mold 105, the air-cooling device 301 is activated to cool the components, ensuring uniform cooling and casting quality, and preventing casting defects caused by localized overheating or overcooling.
