Description

Technical Field

[0001] This application relates to the field of casting cooling equipment technology, for example to a cooling device for casting. Background Technology

[0002] Currently, casting is a metal hot working process that involves pouring molten metal into a casting cavity adapted to the shape of the part, and then allowing it to cool and solidify to obtain the part or blank. Traditional cooling methods include natural cooling, air cooling, and water cooling, but these methods may affect product quality and production efficiency due to uneven cooling, low efficiency, or waste of resources.

[0003] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0004] However, when using traditional air cooling methods to cool castings, the air temperature is constant. At the beginning of cooling, the temperature difference between the casting and the air is large, and the heat exchange efficiency is high. As the temperature continues to drop, the temperature difference between the air and the casting will decrease, and the heat exchange efficiency between the casting and the air will also decrease. This can easily lead to large temperature changes in the casting during cooling, causing the casting to be prone to cracks and hidden damage. Utility Model Content

[0036] Combination Figure 1-5 As shown in the figure, this disclosure provides a cooling device for casting, including: a cooling tank 100; a heat exchange chamber 200 disposed in the middle of the cooling tank 100; a support platform 300 disposed in the upper part of the heat exchange chamber 200; an air inlet pipe 101 disposed in the lower part of the cooling tank 100 below the heat exchange chamber 200, the air inlet pipe 101 being connected to the bottom of the cooling tank 100; a return air pipe 102 disposed in the upper part of the cooling tank 100, the return air pipe 102 being connected to the upper part of the cooling tank 100; and a circulating fan 103 connected to the air inlet pipe 101 and the return air pipe 102 respectively.

[0037] The cooling device for castings provided in this embodiment has a sealed tank structure (cooling tank 100). A heat exchange chamber 200 is located in the middle of the cooling tank 100, dividing it into two spaces: an upper space and a lower space. A support platform 300 on top of the heat exchange chamber 200 supports the casting. Air is supplied to the lower space of the cooling tank 100 through an air inlet pipe 101. The supplied air is cooled by heat exchange in the heat exchange chamber 200 before entering the upper part of the cooling tank 100, thus cooling the casting on the support platform 300. The cooled air is then drawn into a circulating fan 103 through a return air pipe 102, and the circulating fan 103 then cools the air from the air inlet pipe. Air is supplied through unit 101 and circulated within the cooling tank 100 by a circulating fan 103. The circulating fan 103 cools the air through the heat exchange chamber 200 before it enters the support platform 300 to cool the casting. This allows for slow cooling of the casting on the support platform 300. The circulating air is gradually cooled through the heat exchange chamber 200. The air is internally circulated through the cooling tank, inlet pipe, return pipe, and circulating fan. The internally circulated air is cooled through the heat exchange chamber. The air in the cooling tank can match the temperature of the casting. The air in the cooling tank is gradually cooled through the heat exchange chamber, thus cooling the casting.

[0038] Optionally, a plurality of heat exchange tubes 201 are arranged in parallel inside the heat exchange chamber 200, the heat exchange tubes 201 penetrate the heat exchange chamber 200, a drain pipe 202 is connected to the bottom of the heat exchange chamber 200, and a water inlet pipe 203 is connected to the side of the heat exchange chamber 200.

[0039] In this way, the parallel heat exchange tubes 201 inside the heat exchange chamber 200 can facilitate the heat transfer of air through the tubes. The air entering the heat exchange tubes 201 can be cooled. Cold water can be supplied into the heat exchange chamber 200 through the water inlet pipe 203, and the cold water can cool the heat exchange tubes 201, thereby cooling the air. The cooled water can then be discharged through the drain pipe 202. By continuously supplying cold water into the heat exchange chamber 200, the heat exchange tubes 201 can be continuously cooled.

[0040] Optionally, the support platform 300 is spaced apart from the inner wall of the cooling tank 100, a support frame 301 is provided between the support platform 300 and the cooling tank 100, and an air guide plate 302 is hinged between the side of the support platform 300 and the inner wall of the cooling tank 100.

[0041] In this way, the support platform 300 is set on the upper part of the heat exchange chamber 200 inside the cooling tank 100. The support platform 300 is fixedly connected to the inner wall of the cooling tank 100 by the support frame 301. The support frame 301 can fix the support platform 300 on the cooling tank 100. A guide plate 302 is provided between the side of the support platform 300 and the inner wall of the cooling tank 100. The gas flowing out of the heat exchange chamber 200 can enter the upper part of the support platform 300 through the guide plate 302 to cool the casting. The guide plate 302 can guide the air entering the upper part of the support platform 300, so that the cold air can rotate inside the cooling tank 100 and the casting can have better contact and heat exchange with the air.

[0042] Optionally, the air guide plate 302 is hinged to the side wall of the support platform 300, and a collar 303 is hinged to the outer bottom of the air guide plate 302.

[0043] In this way, the air guide plate 302 is hinged to the support platform 300, so that the air guide plate 302 can swing on the support platform 300. The bottom of the air guide plate 302 is provided with a collar on the side away from the support platform 300. The collar 303 is hinged to the air guide plate 302. By rotating the collar 303, all the air guide plates 302 on the support platform 300 can be driven to swing to one side. By adjusting the rotation of the collar 303, the air guide plate 302 can be tilted, thereby guiding the air discharged from the heat exchange chamber 200.

[0044] Optionally, the bottom of the support platform 300 near the heat exchange chamber 200 has a conical structure.

[0045] In this way, the bottom of the support platform 300 is a conical structure, which allows the air in the heat exchange chamber 200 to pass through the support platform 300 more smoothly.

[0046] Optionally, the collar 303 is circular, and the outer side of the collar 303 is in close contact with the inner wall of the cooling tank 100.

[0047] Optionally, the water inlet pipe 203 is arranged along the tangential direction of the heat exchange chamber 200.

[0048] In this way, the water inlet pipe 203 is set in the tangential direction of the heat exchange chamber 200, which allows the liquid entering the heat exchange chamber 200 to rotate within the heat exchange chamber 200. This increases the heat exchange time between the water and the heat exchange pipe 201, thereby increasing the heat exchange efficiency of the water.

[0049] Optionally, an adjustment window 104 is provided on the side wall of the cooling tank 100 near the collar 303. The collar 303 blocks the outside of the adjustment window 104. An adjustment rod 304 is provided on the outside of the collar 303, and the adjustment rod 304 extends out of the adjustment window 104.

[0050] Thus, an adjustment window 104 is provided on the side wall of the cooling tank 100. The adjustment window 104 is located on the outer side wall of the collar 303. The collar 303 can be blocked on the adjustment window 104. An adjustment rod 304 is provided on the side wall of the collar 303. The adjustment rod 304 extends out of the adjustment window 104. The collar 303 can be adjusted by the adjustment rod 304 inside the adjustment window 104. Thus, the collar 303 can be adjusted by the adjustment rod 304 while the cooling tank 100 is sealed. The air guide plate 302 can be adjusted by the collar 303.

[0051] Optionally, an adjustment frame 105 is provided on the outside of the adjustment window 104, and a threaded rod 106 is threadedly connected to one side of the adjustment frame 105. A sliding frame 107 is slidably provided inside the adjustment frame 105, and the sliding frame 107 is sleeved on the adjustment rod 304. The sliding frame 107 is threadedly connected to the threaded rod 106.

[0052] Thus, an adjustment frame 105 is provided outside the adjustment window 104, and the adjustment frame 105 is fitted onto the outside of the adjustment window 104. A sliding frame 107 is slidably arranged inside the adjustment frame 105. A threaded rod 106 is rotatably arranged on one side of the sliding frame 107. The threaded rod 106 is threadedly connected to the adjustment frame 105. The position of the sliding frame 107 can be adjusted by the threaded rod 106 on one side. By rotating the threaded rod 106, the sliding frame 107 can be controlled to a specific position within the adjustment frame 105. The sliding frame 107 is fitted onto the adjustment rod 304. Thus, by adjusting the position of the sliding frame 107, the adjustment rod 304 can be controlled. The adjustment rod 304 can control the collar 303 to adjust the air guide plate 302.

[0053] Optionally, a cooling cover 108 is provided on the upper part of the cooling tank 100, the cooling cover 108 is placed on the cooling tank 100, and a fixing bolt 109 is provided between the cooling cover 108 and the cooling tank 100.

[0054] In this way, the cooling cover 108 on the upper part of the cooling tank 100 can be placed on the cooling tank 100. The cooling cover 108 makes it easy to open the cooling tank 100 and to put in and take out the casting. The cooling tank 100 and the cooling cover 108 are connected in a sealed manner by fixing bolts 109. This way, the cooling tank 100 and the cooling cover 108 can be sealed while also achieving the function of easy opening and closing.
