Description

Technical Field

[0001] The utility model relates to the technical field of casting cooling of a transfer case housing of an automobile, and more specifically to a casting molding cooling device for a transfer case housing of an automobile. Background Art

[0002] The transfer case of a car is a device that distributes the power of the engine. The shell of the transfer case needs to be processed and formed through a casting process. Casting is a relatively early metal heat processing process mastered by humans. It is a method of obtaining parts or blanks after cooling and solidification. After casting, the shell of the transfer case needs to be cooled and formed to improve the preparation efficiency.

[0003] However, generally, castings are cooled by natural cooling, which takes a long time to cool, prolonging the metal casting time and making the work inconvenient. In the prior art, a cooling device is also used in casting. The traditional cooling device cannot automatically cool. When the cooling liquid circulates unevenly in the condenser, it is easy to cause uneven cooling of the molten metal and affect the quality of the casting, thereby reducing the quality of the casting and may cause the failure of the casting process, thereby increasing the cost of the casting process and reducing work efficiency.

[0004] After searching, a Chinese patent with publication number CN212419596U discloses a molding cooling device for casting a transfer case housing of an automobile. The structure is provided with a cooling structure to circulate cold water inside the sand mold tank to cool down the casting parts, which can speed up the cooling speed of the casting parts and ensure that the casting parts will not be damaged, thereby ensuring quality and reducing production costs. In addition, the waste of water resources can be saved through circulation.

[0005] However, when the structure is actually used, the structure transports cold water inside the spiral tube to take away the heat of the casting to achieve the cooling effect. However, there will be more or less impurities in the cold water. During the transportation through the spiral tube, a large amount of impurities and sediments are likely to accumulate inside the spiral tube. In addition, the spiral tube is embedded in the inner wall of the sand mold groove, which makes it difficult to handle the impurities, and the spiral tube is easily blocked. In view of this, the utility model proposes a casting molding cooling device for an automobile transfer case housing. Utility Model Content

[0006] In order to overcome the above defects of the prior art, the utility model provides a casting cooling device for a transfer case housing of an automobile to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a casting cooling device for a transfer case housing of an automobile, comprising a sand mold groove, an inner wall of the sand mold groove is provided with a heat conducting layer, a condensing box is provided on one side of the sand mold groove, a circulating box is provided on one side of the condensing box, a plurality of annular tubes are embedded and installed inside the sand mold groove, a connecting tube is provided between the plurality of annular tubes, the plurality of annular tubes are distributed up and down, and the plurality of annular tubes are connected through the connecting tube, wherein a water inlet pipe is provided at one end of the bottommost annular tube, and a water outlet pipe is provided at one end of the topmost annular tube, a cooling pipe is provided at one end of the water inlet pipe, a high-pressure pump is provided at one end of the cooling pipe, a connecting pipe is provided at the input end of the high-pressure pump, a circulating pipe is provided at one end of the water outlet pipe, the input end of the high-pressure pump is connected to the connecting pipe, one end of the connecting pipe extends to the interior of the condensing box, the output end of the high-pressure pump is connected to the cooling pipe, one end of the circulating pipe extends to the interior of the circulating box, and a cooling machine is connected between the condensing box and the circulating box through a pipeline.

[0008] It can be seen that in the above structure, the high-pressure pump transports cooling water to the inside of multiple annular pipes for circulation, and finally enters the inside of the circulation box. The high-temperature water is cooled by the cooler and then enters the inside of the condensation box again, thereby achieving the recycling of condensed water. The flowing condensed water can take away the heat of the casting inside the sand mold tank, thereby achieving a cooling effect.

[0009] In order to filter the impurities inside the condensed water and avoid the blockage inside the circulation pipe that is difficult to handle, and to facilitate the cleaning of the filter net, preferably, a filter assembly is arranged between the water inlet pipe and the cooling pipe and between the water outlet pipe and the circulation pipe, and the filter assembly includes a filter cartridge, which is connected between the water inlet pipe and the cooling pipe and between the water outlet pipe and the circulation pipe through a pipe flange, and an installation groove is provided on the surface of the filter cartridge, a sealing plate is provided inside the installation groove, a mounting ring is provided inside the filter cartridge, a filter net is installed inside the mounting ring, and the mounting ring is connected to the sealing plate, and the sealing plate is detachably connected to the inside of the installation groove by screws, and a drawing groove is provided on the surface of the sealing plate.

[0011] Technical effects and advantages of the utility model:

[0012] 1. By setting up the filter assembly, the filter net at the mounting ring inside the filter cartridge can filter the condensed water flowing through, so as to prevent the impurities contained in the condensed water from being accumulated inside the annular tube for a long time, making the annular tube blocked and difficult to handle. The impurities filtered by the filter net are inside the mounting ring and on one side of the filter net. The operator can remove the screws at the sealing plate and pull the sealing plate outward through the groove, so that the sealing plate can drive the mounting ring to be pulled out from the inside of the filter cartridge, thereby facilitating the handling of the impurities inside the mounting ring and on one side of the filter net.

[0013] 2. The threaded block is moved by rotating the screw rod, and the slider is guided by sliding on the outside of the slide rod, so that the filter slides from the inside of the mounting ring to the outside.

The impurities filtered by the filter screen 17 are inside the mounting ring 16 and on one side of the filter screen 17. The operator can remove the screws at the sealing plate 15 and pull the sealing plate 15 outward through the groove 23, so that the sealing plate 15 can drive the mounting ring 16 to be pulled out from the interior of the filter cartridge 13, thereby facilitating the treatment of the impurities inside the mounting ring 16 and on one side of the filter screen 17.

[0034] The threaded block 21 is moved by rotating the screw rod 19, and the slider 22 is slidably guided on the outside of the slide rod 20, so that the filter 17 slides from the inside of the mounting ring 16 to the outside. The sliding filter 17 can bring out impurities in the mounting ring 16, and can also take the filter 17 out of the mounting ring 16 for cleaning, thereby avoiding clogging of the filter 17 and facilitating the disassembly and assembly of the filter 17 inside the mounting ring 16.
