Description

Technical Field

[0001] This invention belongs to the field of casting molds, specifically relating to a centrifugal intelligent cooling casting mold and thermal management system. Background Technology

[0002] Centrifugal casting is a highly efficient special casting method, widely used in the production of cylindrical and ring castings such as cylinder liners and rolls. In the centrifugal casting process, the temperature field distribution of the mold and its control precision are key factors that determine the quality of the castings (such as grain size, mechanical properties, and defect rate).

[0003] In existing technologies, centrifugal mold cooling often employs external spraying or internal fixed water channels to cool the mold; however, this cooling method has significant drawbacks:

[0004] Fixed water channels cannot precisely target overheated areas in different regions of the mold, which can easily lead to uneven cooling of the casting, resulting in defects such as stress, deformation, and shrinkage cavities. Furthermore, large temperature fluctuations, the huge thermal shock during pouring, and the temperature fluctuations during the cooling process affect the stability of the casting solidification process.

[0005] This application proposes a centrifugal intelligent cooling casting mold and thermal management system to improve upon the aforementioned deficiencies. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a centrifugal intelligent cooling casting mold and thermal management system with the function of precise local cooling of centrifugal mold.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A centrifugal intelligent cooling casting mold and thermal management system includes a centrifugal mold, roller rings, and a coolant circulation unit. Roller rings are installed at both ends of the outer surface of the centrifugal mold to facilitate contact with the centrifuge and drive the centrifugal mold to rotate centrifugally. The internal part of the centrifugal mold is embedded with a coolant circulation unit, which can accurately control and cool the mold temperature during centrifugal casting.

[0009] In one specific implementation scheme, a PCM temperature control module is installed in the critical heat load area of ​​the centrifugal mold, such as the area corresponding to the pouring gate. The PCM temperature control module is filled with a screened phase change material. As a heat storage unit, the module absorbs a large amount of heat during pouring to slow down the temperature rise; and releases latent heat during the cooling stage to balance temperature fluctuations.

[0010] In one specific implementation scheme, a temperature sensing unit is installed inside the centrifugal mold. The temperature sensing unit is arrayed on the inner surface and key parts of the mold to collect temperature data in real time and transmit the collected data to an external control center. The control center processes the data using a built-in intelligent algorithm model such as PID or fuzzy control algorithm and outputs control signals to the drive unit of the coolant circulation unit to achieve coordinated closed-loop control of the overall flow rate, pressure, and microchannel diameter of each zone of the coolant.

[0011] In one specific implementation scheme, the coolant circulation unit includes a left cooling channel grid, a right cooling channel grid, an inlet pipe, a drain pipe, and a flow control unit. A right cooling channel grid is provided on the other side of the left cooling channel grid. The left cooling channel grid and the right cooling channel grid have the same structure. A flow control unit is installed between the left cooling channel grid and the right cooling channel grid. The inlet pipe and the drain pipe are respectively connected to the end of the left cooling channel grid and the right cooling channel grid near the outside of the centrifugal mold.

[0012] In one specific implementation, the other end of both the inlet pipe and the outlet pipe is connected to an external coolant tank. The coolant inside the tank is driven by a water pump and flows into the coolant circulation unit through the inlet pipe, where it is distributed within the grid.

[0013] In one specific implementation scheme, the flow control unit includes a left pipe, a right pipe, a micro motor, and a valve core structure. The flow control unit has a left pipe and a right pipe on its two sides, respectively. The left pipe and the right pipe are connected to the grid channels on the left cooling channel grid and the right cooling channel grid, respectively. A micro motor is installed on the top of the flow control unit, and a valve core structure is installed inside the flow control unit.

[0014] In one specific implementation scheme, the valve core structure includes a movable body, a top post, a flow groove, a spring, and an inclined post. The top post is installed on the top of the movable body, and several flow grooves are formed on the body of the movable body. A spring is installed at the bottom of the movable body, and the other end of the spring is connected to the inner bottom of the flow control unit. An inclined post is provided directly above the movable body, and the inclined post is connected to the output end of the micro motor. The high point of the inclined surface of the inclined post is in contact with the top post, which is the initial state.

[0015] In one specific implementation scheme, a filter disc and an anti-clogging device are installed in the channel of the left cooling channel mesh near the valve core structure. The filter disc is installed on the inner wall of the cooling channel, and an anti-clogging device is provided on one side of the filter disc. The anti-clogging device is connected to the inner wall of the cooling channel.

[0016] In one specific implementation, the anti-clogging device includes an outer cover, a support unit, a ball screw, and a vibration mechanism. The support unit is installed inside the outer cover, the ball screw is located at the center of the outer cover, and the vibration mechanism is installed at the bottom of the ball screw.

[0017] In one specific implementation scheme, the support unit includes a chassis, movable seats, rollers, cylinders, L-shaped rods, and rotary bearings. A plurality of movable seats are arranged in a square array on the chassis. Rollers are installed at the other end of each movable seat. L-shaped rods are rotatably fitted on each movable seat. The other end of each L-shaped rod is connected to a rotary bearing. The rotary bearing is installed at the center of the chassis. Cylinders are installed on the two opposing sets of movable seats.

[0018] In one specific implementation, the vibration mechanism includes a motor, a guide seat, push rods, connecting rods, an impact block, and elastic balls. The motor is installed at the bottom inside the outer casing and is electrically connected to an external control unit. The output end of the motor is connected to a ball screw. A guide seat is slidably fitted onto the ball screw. A plurality of push rods are arrayed on the outer wall of the guide seat. The other end of the push rods is rotatably connected to the middle of the connecting rod. One end of the connecting rods is rotatably connected to the bottom of the outer wall of the ball screw. The other end of the connecting rod is connected to the impact block. The bottom of the impact block is densely covered with elastic balls.

[0019] According to the technical solution proposed above, the present invention, a centrifugal intelligent cooling casting mold and thermal management system, has the following beneficial effects:

[0020] (1) This invention integrates the coolant circulation unit and the PCM temperature control module into the centrifugal casting mold. Through the real-time temperature feedback of the PCM temperature control module, the coolant flow rate in a specific area can be dynamically adjusted, realizing local precise temperature control from "surface cooling" to "point, line and surface combination", which greatly improves the uniformity of the mold temperature field.

[0021] (2) The present invention provides a valve core structure in the coolant circulation unit, and drives the inclined column to rotate with the help of a micro motor, so that the inclined low surface of the inclined column gradually contacts the top column and squeezes the top column downward, driving the moving body and several flow grooves to move downward synchronously, reducing the exposed flow grooves, thereby reducing the flow of coolant and adjusting it, realizing local precise temperature control and cooling adjustment of centrifugal mold, and improving the casting efficiency of centrifugal mold.

[0022] (3) The present invention provides a support unit in the coolant channel. The piston rod on the cylinder extends and retracts, driving the moving seat to move on the chassis. Under the linkage of the L rod, several moving seats will move synchronously. The length of the extension is adjusted so that the roller can be supported and installed with cooling pipe mesh of different diameters, increasing applicability.

[0023] (4) The present invention provides an anti-clogging device in the coolant channel. The ball screw is driven by a motor to rotate in both directions. Under the guidance of the guide member inside the guide seat, the rotational motion is converted into linear motion, which drives the guide seat to move up and down. During the movement, the impact block will repeatedly impact the filter plate located below through the linkage of the push rod and the connecting rod. The elastic ball at the bottom of the impact block can increase the elasticity when impacting the filter plate, so that the filter screen on the filter plate will vibrate. This can effectively prevent impurities in the coolant from being retained on the filter screen. Even if there is partial blockage, the bypass can still be maintained. Attached Figure Description

Detailed Implementation

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] Example 1: Please refer to Figures 1-6 The specific embodiments of the present invention are as follows:

[0038] A centrifugal intelligent cooling casting mold and thermal management system includes a centrifugal mold 1, roller rings 2 and a coolant circulation unit 3. Roller rings 2 are installed at both ends of the outer surface of the centrifugal mold 1 to facilitate contact with the centrifuge and drive the centrifugal mold 1 to rotate centrifugally. The internal structure of the centrifugal mold 1 is embedded with a coolant circulation unit 3, which can accurately control and cool the mold temperature during centrifugal casting.

[0039] Please see Figure 1 A PCM temperature control module 4 is installed in the critical heat load area of ​​the centrifugal mold 1 (such as the area corresponding to the pouring gate). The PCM temperature control module 4 is filled with selected phase change material. This module acts as a heat storage unit, absorbing a large amount of heat during pouring to slow down the temperature rise; and releasing latent heat during the cooling stage to balance temperature fluctuations. At the contact interface between the PCM temperature control module 4 and the centrifugal mold 1 substrate, a two-step process is adopted: first, a micro-nano scale anchoring structure is manufactured on the mold substrate using laser surface texturing technology; then, a high thermal conductivity metal such as copper or aluminum layer is sprayed onto the texturized surface using low-pressure cold spraying technology to form a mechanical interlock and metallurgical bond, which significantly reduces the interface thermal resistance.

[0040] Please see Figure 1The centrifugal mold 1 is equipped with a temperature sensing unit 5. The temperature sensing unit 5 is arrayed on the inner surface and key parts of the mold to collect temperature data in real time and transmit the collected data to the external control center. The control center processes the data through a built-in intelligent algorithm model (such as PID or fuzzy control algorithm) and outputs control signals to the drive unit of the coolant circulation unit 3 to achieve coordinated closed-loop control of the overall flow rate, pressure and microchannel diameter of each zone of the coolant.

[0041] Please see Figures 2-3 The coolant circulation unit 3 includes a left cooling channel grid 31, a right cooling channel grid 32, an inlet pipe 33, an outlet pipe 34, and a flow control unit 35. The right cooling channel grid 32 is provided on the other side of the left cooling channel grid 31. The left cooling channel grid 31 and the right cooling channel grid 32 have the same structure. The flow control unit 35 is installed between the left cooling channel grid 31 and the right cooling channel grid 32. After being connected by the flow control unit 35, the flow rate of the coolant can be controlled. The inlet pipe 33 and the outlet pipe 34 are respectively connected to the end of the left cooling channel grid 31 and the right cooling channel grid 32 near the outside of the centrifugal mold 1.

[0042] Please see Figures 2-3 The other ends of the inlet pipe 33 and the outlet pipe 34 are connected to the external coolant tank. The water pump in the coolant tank drives the internal coolant to flow into the coolant circulation unit 3 through the inlet pipe 33 and distribute it in the grid to cool the centrifugal mold 1 in all aspects. It can also be discharged from the outlet pipe 34 and flow back to the coolant tank for recycling and cooling.

[0043] Please see Figure 4 The flow control unit 35 includes a left pipe 351, a right pipe 352, a micro motor 353, and a valve core structure 354. The left pipe 351 and the right pipe 352 are respectively provided on both sides of the flow control unit 35. The left pipe 351 and the right pipe 352 are respectively connected to the grid channels on the left cooling channel grid 31 and the right cooling channel grid 32. The micro motor 353 is installed on the top of the flow control unit 35. The valve core structure 354 is installed inside the flow control unit 35. The flow rate of the coolant can be adjusted through the valve core structure 354.

[0044] Please see Figures 5-6The valve core structure 354 includes a movable body 11, a top column 12, a flow channel 13, a spring 14, and an inclined column 15. The top column 12 is installed on the top of the movable body 11. Several flow channels 13 are opened on the body of the movable body 11, which allow the coolant to flow. The spring 14 is installed at the bottom of the movable body 11. The other end of the spring 14 is connected to the inner bottom of the flow control unit 35. An inclined column 15 is provided directly above the movable body 11. The inclined column 15 is connected to the output end of the micro motor 353, which can drive the inclined column 15 to rotate. The high part of the inclined surface of the inclined column 15 is in contact with the top column 12, which is the initial state.

[0045] Please see Figures 5-6 When the moving body 11 and the inclined column 15 are in their initial state, the several flow channels 13 can discharge and flow the coolant. When the flow rate needs to be adjusted, the inclined column 15 is rotated by the micro motor 353, so that the inclined low surface of the inclined column 15 gradually contacts the top column 12. At this time, the top column 12 will be squeezed downward, and the moving body 11 and several flow channels 13 will move downward synchronously, so that the exposed flow channels 13 are reduced, thereby reducing the flow rate of the coolant and adjusting it.

[0046] Example 2: Please refer to Figures 7-10 The specific embodiments of the present invention are as follows:

[0047] Please see Figure 7 A filter disc 311 and an anti-clogging device 312 are installed in the channel of the left cooling channel mesh 31 near the valve core structure 354. The filter disc 311 is installed on the inner wall of the cooling channel and can filter the coolant. An anti-clogging device 312 is provided on one side of the filter disc 311 and is connected to the inner wall of the cooling channel.

[0048] Please see Figure 8 The anti-clogging device 312 includes an outer cover 21, a support unit 22, a ball screw 23, and a vibration mechanism 24. The support unit 22 is installed inside the outer cover 21. The support unit 22 can install the anti-clogging device 312 inside the cooling pipe. The ball screw 23 is located at the center of the outer cover 21, and the vibration mechanism 24 is installed at the bottom of the ball screw 23.

[0049] Please see Figures 8-9The support unit 22 includes a chassis 221, movable seats 222, rollers 223, cylinders 224, L-rods 225, and a rotary bearing 226. Several movable seats 222 are arranged in a four-corner array on the chassis 221 and are slidably engaged with the chassis 221. Rollers 223 are installed at the other end of each movable seat 222. L-rods 225 are rotatably engaged on each movable seat 222. The other end of each L-rod 225 is connected to the rotary bearing 226, which is installed at the center of the chassis 221. Cylinders 224 are installed on two opposing sets of movable seats 222. By extending and retracting the piston rods on the cylinders 224, the movable seats 222 can be moved on the chassis 221. Thus, under the linkage of the L-rods 225, the movable seats 222 will move synchronously. The extended length can be adjusted so that the rollers 223 can be supported and installed with cooling pipe meshes of different diameters.

[0050] Please see Figure 10 The vibration mechanism 24 includes a motor 41, a guide seat 42, push rods 43, connecting rods 44, impact blocks 45, and elastic balls 46. The motor 41 is installed at the bottom inside the outer cover 21 and is electrically connected to an external control unit. The output end of the motor 41 is connected to the ball screw 23 and can drive the ball screw 23 to rotate. The guide seat 42 is slidably fitted on the ball screw 23, which can convert the rotational motion into linear motion. Several push rods 43 are arrayed on the outer wall of the guide seat 42. The other end of the push rods 43 is rotatably connected to the middle of the connecting rod 44. One end of the connecting rod 44 is rotatably connected to the bottom of the outer wall of the ball screw 23. The other end of the connecting rod 44 is connected to the impact block 45. The bottom of the impact block 45 is densely covered with elastic balls 46, which are made of rubber and have elasticity.

[0051] Please see Figures 9-10 The ball screw 23 is driven to rotate in both directions by the motor 41. Under the guidance of the guide member inside the guide seat 42, the rotational motion is converted into linear motion, which can drive the guide seat 42 to move up and down. During the movement, the impact block 45 will repeatedly impact the filter disc 311 located below through the linkage of the push rod 43 and the connecting rod 44. The elastic ball 46 at the bottom of the impact block 45 can increase the elasticity when impacting the filter disc 311, so that the filter screen on the filter disc 311 will vibrate, thereby effectively preventing impurities of coolant from being retained on the filter screen. Even if there is partial blockage, the bypass flow can still be maintained.

[0052] Based on the above embodiments, the specific working principle is as follows:

[0053] When the mold is being centrifugally cast, the casting liquid is poured into the interior of the centrifugal mold 1 and the centrifugal equipment is used to drive the centrifugal mold 1 to rotate and centrifuge. At the same time, when the casting liquid is being poured, the high-temperature molten metal comes into contact with the centrifugal mold 1, and the PCM temperature control module 4 inside the mold starts to absorb heat, like a "sponge" to absorb a large amount of latent heat, which greatly relieves the initial cooling pressure of the coolant circulation unit 3 and avoids a sudden rise in the temperature of the inner surface of the mold.

[0054] Then, during the centrifugal solidification stage, the water pump in the coolant tank drives the internal coolant to flow. The coolant flows into the coolant circulation unit 3 through the inlet pipe 33 and is distributed in the grid to cool the centrifugal mold 1 in all directions. It can also be discharged from the drain pipe 34 and flow back to the coolant tank for recycling and cooling. Then, the control center identifies which areas of the centrifugal mold 1 are overheating due to the completion of the PCM phase change or the large thickness of the casting based on the data transmitted by the temperature sensing unit 5. At this time, the micro motor 353 drives the tilting column 15 to rotate, so that the tilted low surface of the tilting column 15 gradually contacts the top column 12. At this time, the top column 12 is squeezed downward, and the moving body 11 and several flow channels 13 move downward synchronously, reducing the exposed flow channels 13, thereby reducing the flow of coolant and adjusting it. The flow of coolant in the corresponding area can be dynamically adjusted to perform precise secondary forced cooling.

[0055] Then, when the casting is basically formed and the overall temperature drops, the PCM module begins to release heat, which slows down the overall cooling rate of the mold, helps release stress in the casting, and prevents cracking.

[0056] In the description of this invention, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0057] The control method of the present invention is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Therefore, the present invention will not explain the control method and circuit connection in detail.

[0058] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
