[0001] The utility model belongs to the technical field of sand mold cooling, and more specifically, particularly relates to a cooling device used for sand mold casting. Background Art

[0002] In various casting processes, in order to ensure the quality of castings, it is sometimes necessary to take certain measures to control the local cooling rate of castings, so as to change the solidification sequence and reduce the occurrence of shrinkage defects. In sand casting, chillers are often set at hot spots to speed up the local cooling rate of castings. In investment casting, air cooling is carried out on the surface of the shell to achieve the cooling effect.

[0003] After searching, for example, the patent number CN212734110U discloses a cooling device for sand mold casting, which relates to the technical field of cooling devices. The cooling device for sand mold casting includes a liquid cooling pool and a sand mold tray. The left side of the liquid cooling pool is fixedly connected to a No. 1 controller, and the right side of the liquid cooling pool is fixedly connected to a No. 2 controller. The bottom of the inner wall of the No. 1 controller and the No. 2 controller are fixedly connected to a sliding lifter, and the right bottom of the sliding lifter is fixedly connected to a positioner, and both sides of the sand mold tray are fixedly connected to a lifting slider. The utility model first places the sand mold in the sand mold tray, and then controls the transmission gears inside the No. 1 controller and the No. 2 controller to rotate through the control knob, thereby driving the lifting sleeve rod inside the sliding lifter to move downward, and then driving the sand mold tray to move downward through the lifting slider, so that the sand mold tray drives the sand mold to invade the liquid cooling pool to achieve the purpose of cooling.

[0004] The cooling device in the above patent currently still has the following shortcomings:

[0005] Although the cooling structure in the above patent can cool the sand mold, it is impossible to accurately grasp the temperature change of the sand mold during the process of immersing the sand mold in the coolant for cooling. Therefore, the cooling time can only be roughly estimated through experience, which makes it impossible to judge the cooling time and cooling effect well. On the one hand, the quality of the product may be affected due to insufficient cooling, and on the other hand, the work efficiency may be affected due to too long cooling time.

[0023] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.

[0024] Embodiment 1:

[0025] As attached Figure 1 To Attachment Figure 6 As shown:

[0026] The utility model provides a cooling device for sand mold casting, comprising: a cooling trough 1; the cooling trough 1 adopts a rectangular groove structure, and a coolant is arranged inside the cooling trough 1; the inner side of the cooling trough 1 is fixedly provided with four groups of cylindrical fixing rods 102 in a rectangular array shape; a placement trough 2 is slidably arranged between the four groups of fixing rods 102, the placement trough 2 adopts a rectangular groove structure, and the bottom of the placement trough 2 is provided with a through-type circular through-groove structure in a rectangular array shape, and a through-type circular through-groove structure is opened on one side of the bottom of the placement trough 2; a temperature tube 201 with a U-shaped tube structure is fixedly arranged in the circular through-groove at the bottom of the placement trough 2, and mercury is arranged in the temperature tube 201; a group of connecting tubes 202 are fixedly arranged on the top of both ends of the temperature tube 201, the connecting tube 202 adopts an internally hollow cylindrical structure, and the top of the connecting tube 202 is provided with a through-type circular through-groove structure, and mercury is arranged at the bottom of the connecting tube 202.

[0027] Among them, a group of cylinders 101 are fixedly arranged on both sides of the top of the cooling tank 1, and the two groups of cylinders 101 are transmission-connected to the placement tank 2.

[0028] Among them, a sliding rod 203 with a cylindrical structure is slidably arranged in the circular through groove at the top of the connecting cylinder 202, and a spring is sleeved on the outer side of the sliding rod 203; a warning light 205 is fixedly arranged at the top of the sliding rod 203; a piston plate 204 is fixedly arranged at the bottom end of the sliding rod 203, and the piston plate 204 adopts a circular plate structure, and the outer wall of the piston plate 204 fits with the inner wall of the connecting cylinder 202.

[0029] The specific usage and function of this embodiment are as follows:

[0030] When in use, the sand mold to be cooled is placed in the middle of the placement tank 2, and then the placement tank 2 is driven to slide downward along the fixed rod 102 to the inside of the cooling tank 1 by starting the two groups of cylinders 101, and the sand mold in the placement tank 2 is preliminarily cooled by the coolant in the cooling tank 1. When the sand mold is just placed in the placement tank 2, due to the high temperature of the sand mold itself, it will be transmitted to the temperature tube 201, and the mercury in the temperature tube 201 will expand due to the heat, so that the mercury in the temperature tube 201 and the connecting tube 202 push the piston plate 204 to move upward, and the sliding rod 203 moves upward along the connecting tube 202, thereby synchronously driving the warning light 205 to rise upward, and the warning light 205 is used to remind the staff, and the staff can monitor the temperature of the sand mold by observing the height of the warning light 205. When the temperature of the sand mold decreases, the temperature transmitted to the temperature tube 201 will also decrease, which can make The mercury temperature in the temperature tube 201 and the connecting tube 202 is reduced, so that the volume of mercury is restored and the pressure on the piston plate 204 is lost. At this time, the piston plate 204 and the slide rod 203 slide downward and reset under the action of the spring on the outer side of the slide rod 203, thereby driving the warning light 205 to move downward and reset. At this time, after the staff observes the position of the warning light 205, they can start the two groups of cylinders 101 to drive the placement groove 2 to rise from the inside of the cooling groove 1, completing the cooling process of the sand mold in the placement groove 2. At the same time, the two groups of cooling fans 105 can be started synchronously for further heat dissipation treatment to complete the entire treatment process of the sand mold. During the whole process, the real-time temperature of the sand mold can be monitored through the temperature tube 201 and reacted through the warning light 205. The staff can know the temperature of the sand mold in real time, which can help to more accurately control the cooling time of the sand mold and improve work efficiency.
