Description

Technical Field

[0001] This invention belongs to the field of casting processing technology, and specifically discloses a water circulation cooling device for die casting. Background Technology

[0002] For castings with complex structures, such as steering gears, immersion cooling is typically employed after high-temperature casting to rapidly reduce the temperature of the castings after machining and ensure dimensional accuracy. Immersion cooling is a widely used, highly efficient heat exchange method. Currently, most immersion cooling equipment is equipped with a basic water circulation system, which, after simple treatment, is then returned to the cooling area. This reduces water consumption while maintaining the continuity of the cooling process and meeting the cooling requirements of batch castings.

[0003] However, when using immersion cooling to cool castings such as steering gears, the castings are mostly in a static state and lack movement during the cooling process. Steering gears and other castings often have complex structures such as internal holes and corners. During static cooling, these areas are prone to forming dead zones for water flow, making it difficult for cooling water to flow fully. This results in inconsistent heat exchange rates in different areas of the casting. Furthermore, the cooling water mostly circulates naturally. When the casting enters the cooling zone, the surrounding cooling water cannot be concentrated in a directional manner to enhance the heat exchange effect. After the casting leaves, the cooling water is also difficult to quickly restore a uniform distribution, affecting the cooling efficiency of subsequent castings and reducing the utilization efficiency of cooling water in the water circulation system. Summary of the Invention

[0004] In view of this, the technical problem to be solved by the present invention is to provide a water circulation cooling device for die casting, so as to solve the problem that castings such as steering gears often have complex structures such as internal holes and corners, and these areas are prone to forming water flow dead zones during static cooling, making it difficult for cooling water to flow fully, resulting in inconsistent heat exchange rates in different areas of the casting.

Each of the two transmission rods is fitted with a compression spring on its outer wall. A pull plate is fixedly connected to the upper end of the two transmission rods, and a compression plate is fixedly connected to the lower end of the two transmission rods.

[0007] In the above technical solution, preferably, the upper end of the partition plate is slidably connected to the guide groove through a second round shaft, and the end of the second round shaft is arc-shaped. A reset spring is sleeved on the end of the second round shaft away from the guide groove, and a circular plate is fixedly connected to the end of the second round shaft away from the guide groove.

[0009] In the above technical solution, preferably, two guide rods are fixedly connected to the upper end of the bracket, and lifting springs are sleeved on the outer walls of the two guide rods. A horizontal plate is slidably connected to the upper ends of the two guide rods corresponding to the lifting springs. The two ends of the lifting springs are fixedly connected to the bracket and the horizontal plate, respectively, and the middle of the horizontal plate corresponds to the top block.

[0010] In the above technical solution, preferably, a first extrusion plate is fixedly connected to both ends of the horizontal plate, and a second extrusion plate is fixedly connected to the inner side of the horizontal plate near the first extrusion plate, with the side of the first extrusion plate opposite to the second extrusion plate corresponding to the outer wall of the round rod.

[0011] In the above technical solution, preferably, the cooling water collection assembly further includes a water storage tank disposed on one side of the cooling box, the water storage tank being fixedly connected to the base plate, and a circulating water pump being fixedly installed on the upper end of the water storage tank.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The guide groove formed by the first guide plate and the second guide plate, together with the movement of the first and second round shafts driven by the lifting rod, makes the casting flip with the partition plate around the first round shaft. This flipping action can break the dead angle of water flow in the inner hole and corner of the steering gear, so that all surfaces of the casting can fully contact the flowing cooling water, and the air in the inner hole of the casting can be discharged, ensuring that the heat exchange rate of each area of ​​the casting is consistent, avoiding the casting accuracy deviation caused by uneven local cooling. The flipping process does not require an additional power source, and can be achieved by relying on the weight of the component and the guide structure. This simplifies the equipment structure and improves the cooling uniformity. In addition, during the cooling and reset process after flipping, the inner hole of the casting faces downward, effectively discharging the internal moisture.

[0017] (2) When the lifting rod moves the casting down to the cooling area, the top block squeezes the horizontal plate, and the first squeezing plate pushes the collecting plate to move in opposite directions, so that the cooling water gathers in the casting area, enhancing the flow rate and heat exchange efficiency of the cooling water around the casting; when the casting is cooled, the lifting rod drives the top block to rise, the lifting spring pushes the horizontal plate to reset, and the second squeezing plate drives the collecting plate to move in opposite directions, so that the cooling water is restored to a uniform distribution, preparing for the next cooling, and further improving the utilization efficiency of the cooling water.

A support mold 15 is fixedly installed on the upper end of the bearing plate 14.

[0032] A base plate 16 is fixedly connected to the upper end of the partition plate 13 near the supporting mold 15. Two transmission rods 17 are slidably connected through the base plate 16. Each transmission rod 17 has a compression spring 18 sleeved on its outer wall. A pull plate 19 is fixedly connected to the upper end of the two transmission rods 17, and a compression plate 20 is fixedly connected to the lower end of the two transmission rods 17. A second round shaft 21 is slidably connected through the upper end of the partition plate 13 corresponding to the guide groove 6. The end of the second round shaft is arc-shaped. A return spring 22 is sleeved on the end of the second round shaft 21 away from the guide groove 6. A circular plate 23 is fixedly connected to one end of the guide groove 6. The cooling water collection assembly includes two sliding grooves 24 on one side of the cooling box 3. A rectangular block 25 is slidably connected in the sliding groove 24. A round rod 26 is fixedly connected through the rectangular block 25. A collection plate 27 is fixedly connected to the round rod 26 corresponding to the cooling box 3. A bracket 28 is fixedly connected to the other end of the cooling box 3 corresponding to the round rod 26. Two guide rods 29 are fixedly connected to the upper end of the bracket 28. A lifting spring 30 is sleeved on the outer wall of each of the two guide rods 29. The upper ends of the two guide rods 29 and the lifting springs 30 are connected together. A sliding connection includes a horizontal plate 31. The lifting spring 30 is fixedly connected at both ends to the bracket 28 and the horizontal plate 31, respectively. The middle of the horizontal plate 31 corresponds to the top block 9. Two first extrusion plates 32 are fixedly connected to both ends of the horizontal plate 31. Two second extrusion plates 33 are fixedly connected to the inner side of the horizontal plate 31 near the two first extrusion plates 32. The side of the first extrusion plates 32 and the second extrusion plates 33 opposite to each other corresponds to the outer wall of the round rod 26. The cooling water collection assembly also includes a water storage tank 34 disposed on one side of the cooling box 3. The water storage tank 34 is fixedly connected to the bottom plate 2. A circulating water pump 35 is fixedly installed at the upper end. The outlet of the circulating water pump 35 is connected to a drain pipe 36, which is connected to the cooling tank 3. The lower end of the water storage tank 34 is connected to an inlet pipe 37, which is connected to the water storage tank 34. Universal wheels 38 are fixedly connected to the four corners of the lower end of the frame 1. A protective chamber 39 is fixedly installed on the outer wall of the frame 1 corresponding to the base plate 2. The protective chamber 39 has an L-shaped structure design. The guide groove 6 has a four-section structure, two of which are vertical through grooves extending in the vertical direction, and the other two are arc-shaped through grooves connecting the two vertical through grooves.

[0033] Working principle:

[0034] Before cooling, the circulating water pump 35 at the top of the water storage tank 34 is started. The circulating water pump 35 serves as a power source to transport the cooling water in the water storage tank 34 to the interior of the cooling box 3 through the drain pipe 36 connected to its outlet end. At the same time, the cooling water in the cooling box 3 that has been heated after subsequent use can flow back to the water storage tank 34 through the water inlet pipe 37 connected to the bottom end of the cooling box 3, forming a closed-loop water circulation to continuously provide a low-temperature water source for cooling the casting and avoid the cooling water from overheating after a single use, which could lead to cooling failure.

[0035] When the casting is fixed, pull the pull plate 19 upwards. The pull plate 19 drives the two transmission rods 17 fixed to it to slide upwards along the base plate 16. At this time, the two compression springs 18 sleeved on the upper ends of the two transmission rods 17 are squeezed by the pull plate 19 and the base plate 16, and enter the storage state. At the same time, the compression plate 20 fixed at the lower end of the transmission rods 17 moves upwards, and the upper space of the support mold 15 is opened. After the steering gear to be cooled is placed on the upper positioning surface of the support mold 15, the pull plate 19 is released. The two compression springs 18 lose tension and restore their deformation, generating a downward elastic thrust, which is transmitted to the compression plate 20 through the two transmission rods 17, so that the compression plate 20 is pressed tightly downwards against the upper end of the steering gear, and the steering gear is firmly fixed on the support mold 15 to prevent the steering gear from shifting or bumping due to water flow impact or component movement when it is subsequently immersed in cooling water.

[0036] When the casting is immersed in cooling, the lifting rod 8 is activated, and the output end of the lifting rod 8 extends downward, simultaneously driving the top block 9 and the protrusion 10 on the output end to move. The protrusion 10 drives the transmission plate 11 fixed on one lower side to move downward. The transmission plate 11 drives the first round shaft 12 rotatably connected at the lower end. The first round shaft 12 drives the partition plate 13 fixed on one side. The partition plate 13 drives the lower bearing plate 14, the supporting mold 15, the upper base plate 16, the transmission rod 17, the compression spring 18, the pull plate 19, the compression plate 20, and the second round shaft 21 that is slidably connected through it to move. The entire assembly... The component moves downward along the guide groove 6 naturally formed between the first guide plate 4 and the second guide plate 5, gradually immersing the steering gear into the cooling water in the cooling tank 3. When the first round shaft 12 moves to the lower end of the guide groove 6, the steering gear is completely submerged in the cooling water. At this time, the second round shaft 21 enters the arc-shaped through-slot section of the guide groove 6. Under the weight of the steering gear, the supporting mold 15, the bearing plate 14, and other components, the partition 13 rotates clockwise around the first round shaft 12 as the rotation center along the lower end of the guide groove 6, and the second round shaft 21 slides from the upper end of the first round shaft 12 to the side end. This rotational action causes the steering gear to rotate slowly in the cooling water, so that all surfaces of the steering gear, such as the inner hole and the outer wall, are evenly in contact with the cooling water, and the air in the hole is discharged. This avoids local areas that are difficult to deeply contact with the cooling water for cooling, which could cause internal stress, deformation, or cracking of the casting due to temperature difference. At the same time, the rotation of the steering gear can also agitate the cooling water in the cooling tank 3, breaking up hot spots where the water temperature rises locally, and ensuring a uniform and stable cooling effect.

[0037] When the lifting rod 8 descends, as the lifting rod 8 moves the top block 9 to the lowest point, the top block 9 contacts and presses the horizontal plate 31 in the cooling water collection assembly. The horizontal plate 31 slides downward along the two guide rods 29, simultaneously compressing the two lifting springs 30 sleeved on the outer walls of the two guide rods 29, causing the two lifting springs 30 to enter a storage state. The horizontal plate 31 drives the two first extrusion plates 32 fixed at both ends to move downward, and the two first extrusion plates 32 contact and press the outer wall of the round rod 26. Under the extrusion force, the round rod 26 drives the rectangular blocks 25 at both ends to slide towards each other along the two slide grooves 24. At the same time, the round rod 26 drives the corresponding collection plates 27 of the cooling box 3 to move towards each other. The two collection plates 27 converge towards the middle of the cooling box 3, pushing the cooling water to concentrate in the area where the steering gear is located, enhancing the water flow speed and cooling water volume around the steering gear, and further improving the cooling efficiency.

[0038] When the lifting rod 8 rises, after the steering gear has cooled down, the output end of the lifting rod 8 retracts upward, and the lifting rod 8 drives the top block 9 and the protrusion 10 to rise synchronously. The squeezing force of the top block 9 on the horizontal plate 31 disappears, and the two lifting springs 30 restore their deformation and generate an upward elastic thrust, pushing the horizontal plate 31 to slide upward and reset along the two guide rods 29. The horizontal plate 31 drives the two second squeezing plates 33, which are fixed close to the inner side of the two first squeezing plates 32, to move upward. The two second squeezing plates 33 contact the outer wall of the round rod 26 and squeeze the round rod 26, so that the round rod 26 drives the rectangular block 25 to slide back and forth along the two sliding grooves 24. The round rod 26 synchronously drives the two collecting plates 27 to move back and forth, diverting the cooling water in the middle of the cooling box 3 to both sides, restoring the uniform distribution of the cooling water, and preparing for the water flow to converge during the next casting cooling, avoiding the long-term concentration of cooling water in the middle and causing local temperature rise.

[0039] When the casting is removed, the lifting rod 8 raises the partition 13 and related components to the operating height. During this process, the first round shaft 12 and the second round shaft 21 move upward along the vertical through-slot section of the guide groove 6. At this time, the inner hole of the steering gear is vertically downward, and the water in the hole naturally falls down. When the first round shaft 12 moves to the initial position along the vertical through-slot section of the guide groove 6, the teaching robot assists in gripping the steering gear and pulling the pull plate 19. The pull plate 19 drives the two transmission rods 17 and the pressing plate 20 to move, releasing the pressing plate 20 from fixing the steering gear. At the same time as pulling the pull plate 19, the teaching robot rotates the pull plate 19 counterclockwise. The pull plate 19 then moves through the transmission rods 17 and the pressing plate 20 to release the pressing plate 20 from fixing the steering gear. The moving rod 17 drives the base plate 16, partition plate 13, and first round shaft 12 to rotate on the transmission plate 11. During the rotation, the second round shaft 21 contacts the inclined end of the flip plate 7. The second round shaft 21, which is compressed, then squeezes the return spring 22 through the circular plate 23. With the transmission of rotational force, the second round shaft 21 rotates 90 degrees and passes over the flip plate 7 into the guide groove 6, releasing the pull plate 19. The return spring 22 restores its deformation and presses the second round shaft 21 tightly into the guide groove 6, so that the partition plate 13, bearing plate 14, support mold 15 and other components return to their initial positions. The entire device is reset and awaits the next cooling operation of the steering gear.

[0040] In addition, the casters 38 fixed at the four corners of the lower end of the frame 1 can facilitate the overall movement of the device to meet the needs of different processing stations; the L-shaped protective chamber 39 fixed to the base plate 2 on the outer wall of the frame 1 can prevent cooling water from splashing to the outside during the cooling process, and at the same time protect the internal components from external collision damage.
