Description

Technical Field

[0001] The invention relates to the field of casting processing, and in particular to a rapid cooling device for casting processing. Background Art

[0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain objects with a certain shape, size and performance.

[0003] In the casting process, cooling treatment is a crucial step. Its purpose is to allow the temperature of the casting to drop steadily from a high temperature state to a balance with the ambient temperature. This process not only affects the production efficiency of the casting, but is also directly related to the quality of the final product. Water cooling is a rapid cooling method. By placing the freshly cast casting into cold water, it can be quickly cooled to room temperature. However, this method has significant risks. When the casting is at a high temperature, direct immersion in cold water will cause its surface to shrink sharply, while the interior still maintains a high temperature. This temperature difference between the inside and the outside will produce large thermal stresses. These thermal stresses may cause cracks or deformation in the casting, seriously affecting the quality and performance of the finished product. In order to avoid the above problems, it is chosen to extend the cooling path of the casting on the conveyor belt so that the casting can be gradually cooled before entering the next process. However, this method requires a larger production site and may reduce the overall production efficiency. Therefore, there is room for improvement. It is necessary to produce a rapid cooling device for casting processing to solve the above problems. Summary of the invention

The weight of the movable frame 5 exceeds the weight of the casting mold base 6, and the distance from the lower surface of the cooling seat 3 to the cooling workbench 1 is equal to the height of the movable frame 5.

[0021] In this embodiment, when the casting is processed for cooling operation, the control panel 27 is used to control the opening and closing of the electric sliding door 24, so that the conveyor belt can move the movable frame 5 to the inside of the U-shaped cover 2 and the cooling seat 3. The control panel 27 controls the motor 23 to start. Under the transmission action of the connecting shaft 22, the two sets of chains 21 rotate synchronously. The movable frame 5 located on the upper surface of the cooling workbench 1 moves toward the outlet of the cooling device along the slide 26 as a whole under the action of the push plate 211. There are multiple sets of temperature sensors inside the cooling seat 3, which can detect the temperature of each interval in real time. When the movable frame 5 moves as a whole to the bottom of the air cooling bin 31, if the temperature detected by the temperature sensor inside the air cooling bin 31 exceeds the preset temperature, the sensor in the control panel 27 controls the air pump 311 to start, and the cold air is used for preliminary cooling.When the temperature is lower than the preset temperature, under the action of the push plate 211, the moving frame 5 moves to the bottom of the spray bin 32. If the temperature detected by the temperature sensor inside the spray bin 32 exceeds the preset temperature, the control panel 27 controls the liquid pump 322 to start spraying and cooling again until the temperature detected by the temperature sensor inside the spray bin 32 is lower than the preset temperature. Subsequently, under the action of the push plate 211, the moving frame 5 enters the spray bin 32 area. Under the action of the special-shaped groove 25, the casting mold base 6 inside the moving frame 5 drops as a whole and enters the liquid refilling tank 4 for ultimate cooling. In the mold base 6, the upper rack 251 and the lower rack 253 are arranged alternately, and cooperate with the short rack 252, so that the casting mold base 6 swings left and right and rotates alternately, so that the casting inside the casting mold base 6 is fully in contact with the water, and the cooling efficiency is further accelerated. After the cooling is completed, under the action of the special-shaped groove 25, the casting mold base 6 returns to the initial position, and under the action of the long rack 254, the casting mold base 6 rotates to throw out the water, thereby improving the water recovery rate. The moving frame 5 as a whole ends the cooling work under the action of the push plate 211 controlled by the sensor in the control panel 27, which facilitates the subsequent demoulding and other processes of the casting. The casting is cooled in a controlled manner in stages, avoiding quality problems that may be caused by direct water cooling, while shortening the cooling path and improving the overall cooling efficiency. It should be noted that the upper rack 251, short rack 252, lower rack 253 and long rack 254 inside the connecting groove 34 are provided with multiple groups to ensure that the casting is fully cooled. When the distance sensor 28 detects that the moving frame 5 moves, the conveyor belt automatically loads the material, and the steam generated inside the spray bin 32 and the cooling bin 33 is conveyed through the guide pipe B35 and the connecting groove 34, and the refilling tank is conveyed through the connecting pipe 41. 4, the steam generated inside is guided to the cooling workbench 1 and the cooling seat 3 on one side of the connecting pipe 41, and the excess steam inside the air cooling bin 31 is also transported to the side of the connecting pipe 41 through the guide pipe A313. These steam and waste heat pre-cool the casting mold base 6 inside the moving frame 5 as a whole, shortening the overall cooling time in the later stage, fully recycling existing resources, and being more energy-saving and environmentally friendly. At the same time, it should be noted that the protective plate 7 can move up and down in the vertical direction through the spring B661, which can not only protect the casting mold base 6 as a whole, but also facilitate the staff to carry out later maintenance. ;

[0022] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
