Description

Technical Field

[0001] This utility model relates to the field of casting cooling technology, specifically a casting cooling device after pouring. Background Technology

[0002] Casting cooling refers to the process by which a casting, after being poured and solidified, cools from a high temperature to room temperature. During this process, the casting's temperature, microstructure, properties, and stress state all change. Understanding casting cooling is crucial for controlling casting quality, avoiding defects, and optimizing process parameters.

[0003] During the cooling process, inconsistent cooling rates in different parts of the casting can lead to thermal stress. Controlling the cooling process can reduce or eliminate these stresses and prevent the casting from deforming or cracking. While common methods of rapid cooling such as spraying or immersion can improve cooling efficiency, the inconsistent cooling rates inside and outside the casting can lead to certain product damage risks. Therefore, it is necessary to design a multi-stage cooling device for cooling treatment. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0019] Please see Figure 1-4 This utility model provides a technical solution including a ring track 1, a hanging basket 4, an air-cooled box 2, a water-cooled box 3, and a control cabinet 6. The control cabinet 6 is located on the side of the air-cooled box 2 away from the water-cooled box 3. The ring track 1 is located above the air-cooled box 2 and the water-cooled box 3. Track blocks 5 are equidistantly slidably installed on the ring track 1. A hanging rod 53 is fixed to the lower end of the track block 5. A connecting rod 41 is fixed to the upper end of the hanging basket 4. A rotating component is provided between the connecting rod 41 and the hanging rod 53. A fan 21 is installed on the side wall of the air-cooled box 2, and a partition 22 is fixed to the bottom. A radiator 31 and a circulating pump 32 that drives the liquid flow in the radiator 31 are installed on the water-cooled box 3. The radiator 31 is provided with a heat absorption section and a heat dissipation end, and the heat absorption section is located inside the water-cooled box 3. A water temperature sensor is provided inside the water-cooled box 3.

[0020] A track groove 11 is provided on the outer side of the circular track 1. A fixed rack 12 is fixed in the track groove 11. A synchronous walking motor 51 is fixed on the track block 5. The output end of the synchronous walking motor 51 is located in the track groove 11 and a drive gear 52 is fixed thereon. The drive gear 52 meshes with the fixed rack 12. The synchronous walking motor 51 can drive the drive gear 52 to rotate. The meshing transmission of the fixed rack 12 can make the track block 5 slide along the circular track 1. The circular track 1 is provided with a high and low undulating structure. The circular track 1 at the air-cooled box 2, water-cooled box 3 and loading and unloading positions is lower than other positions. Since the circular track 1 above the air-cooled box 2 and water-cooled box 3 is lower, the basket is inserted into the air-cooled box 2 and water-cooled box 3.

[0021] A check valve assembly 7 is provided between the annular track 1 and the track block 5. The check valve assembly 7 includes a mounting groove 71 and a serrated block 74. The mounting groove 71 is opened on the outside of the annular track 1, and a serrated strip 72 is fixed in the mounting groove 71. The serrated block 74 is installed on the inside of the track block 5 and its position is aligned with the mounting groove 71. A telescopic groove 73 is opened on the inside of the track block 5 and at a position corresponding to the serrated block 74. A push-out spring 75 is fixed between the inner wall of the telescopic groove 73 and the serrated block 74. When the track block 5 slides in the forward direction, the inclined surface of its serrated block 74 will continuously press against the inclined surface of the serrated strip 72 and compress the push-out spring 75, which can achieve normal sliding. When sliding in the reverse direction, the plane of the serrated block 74 abuts against the plane of the serrated strip 72, and reverse sliding cannot be achieved, ensuring the stable operation of the track block 5.

[0022] The rotating assembly includes a connecting sleeve 54 and a fixed gear 42. The connecting sleeve 54 is fixed to the bottom of the hanging rod 53. The upper end of the connecting rod 41 is rotatably connected inside the connecting sleeve 54. The fixed gear 42 is fixed to the outer periphery of the connecting rod 41. A drive motor 55 is fixed to the outer side of the connecting sleeve 54. A transmission gear 56 that meshes with the fixed gear 42 is fixed to the output end of the drive motor 55.

[0023] A pressure plate 44 is installed inside the hanging basket 4. A cylinder 43 is installed on the top of the hanging basket 4 to drive the pressure plate 44 to extend and retract. Top rods 45 are fixed at equal intervals at the bottom of the pressure plate 44. Ventilation holes are provided on the side wall and bottom of the hanging basket 4. Driven by the cylinder 43, the pressure plate 44 is pressed down, so that the top rods 45 press down against the casting to fix the casting and prevent it from falling during the transportation process.

[0024] Working principle: First, connect the entire device to an external power source. Then, place the casting into the hanging basket 4. The synchronous walking motor 51 drives the drive gear 52 to rotate, and the meshing transmission of the fixed rack 12 allows the track block 5 to slide along the circular track 1. Since the circular track 1 above the air-cooled box 2 and the water-cooled box 3 is lower, the hanging basket is inserted into the air-cooled box 2 and the water-cooled box 3. In the air-cooled box 2, the fan 21 accelerates the airflow to achieve initial cooling. In the water-cooled box 3, the casting can be immersed in water for rapid cooling. The cooling process achieves multi-stage cooling, reducing the risk of damage to the casting. Secondly, when the casting is placed inside the hanging basket 4, the cylinder 43 can be used to drive the pressure plate 44 to press down, causing the top rod 45 to press down against the casting and fix it, preventing it from falling during transportation. Then, the output end of the drive motor 55 drives the transmission gear 56 to rotate, and the fixed gear 42 drives the connecting rod 41 and the hanging basket 4 to rotate. As the hanging basket 4 enters the air-cooling box 2, it rotates slowly and continuously, which can make the surface of the casting cool down more evenly.
