Description

Technical Field

[0001] The present invention belongs to the technical field of metal casting, and specifically relates to a cooling device for metal casting. Background Art

[0002] Metal casting is a process of melting metal into a liquid that meets certain requirements, pouring it into a mold, and after cooling, solidifying, and finishing, obtaining a casting with a predetermined shape, size, and performance. During the metal casting process, it is necessary to cool the casting mold.

[0003] A patent application with the publication number CN118371692B discloses a cooling device for a metal casting mold. Through the cooling mechanism, the metal casting mold can be quickly and conveniently clamped and fixed. And through four mounting sleeves, one of the mounting sleeves can enter the spraying mechanism for cooling work, and the other mounting sleeves can be used for loading and unloading work, thereby effectively reducing the cooling time of the mold. Through the operation of the rotating mechanism, the mold in the mounting sleeve can be rotated. And after entering the spraying device, the mold can move up and down and vibrate left and right, so that the cooling water can be better sprayed onto the mold for cooling, solving the problem that after the mold is clamped and fixed by the clamping component and then directly placed in the cooling tank for cooling, the mold is in a static state in the cooling tank, resulting in some corners of the mold not achieving the ideal cooling effect, and improving the cooling efficiency of the cooling device.

[0004] In the above-mentioned prior art, when cooling the mold, water cooling is usually used. Through holes are usually provided inside the mold, and cold water is injected into the mold to cool it. The cooling efficiency is relatively low. Scale will be generated after long-term use of the through holes inside the mold, resulting in uneven heat dissipation and affecting the heat dissipation effect of the mold.

Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] Embodiment 1: As Figures 1-5As shown in the figure, a cooling device for metal casting according to an embodiment of the present invention includes a U-shaped frame 1. A conveying component is provided on one side of the U-shaped frame 1. The conveying component includes a cylindrical rod 3 rotatably provided on one side of the U-shaped frame 1. Rectangular plates 31 are fixedly connected to the periphery of the upper end of the cylindrical rod 3. A lower mold 5 and an upper mold 51 are placed on the upper ends of the rectangular plates 31. The opening of the U-shaped frame 1 faces the side of the cylindrical rod 3. A spraying component is provided inside the U-shaped frame 1. The spraying component includes arc-shaped strips 2 slidably provided on both sides inside the U-shaped frame 1. Spray nozzles 21 are provided on the opposite sides of the arc-shaped strips 2. Spiral holes 52 are respectively provided inside the lower mold 5 and the upper mold 51. Fourth connecting pipes 53 are fixedly connected to both ends of the spiral holes 52. A first pipe 13 is slidably provided at a position corresponding to the fourth connecting pipe 53 on one side inside the U-shaped frame 1.

[0023] Specifically, after pouring the metal mold, it is necessary to cool the mold to enable the molten metal inside the mold to quickly take shape. When cooling the mold, water cooling is usually used for cooling. Through holes are usually provided inside the mold, and cold water is injected into the mold to cool the mold. The cooling efficiency is relatively low. Scale will be generated after the through holes provided inside the mold are used for a long time, resulting in uneven heat dissipation and affecting the heat dissipation effect of the mold. When using this cooling device, place the lower mold 5 and the upper mold 51 on the upper ends of the rectangular plates 31, then pour between the lower mold 5 and the upper mold 51. Subsequently, the cylindrical rod 3 rotates to drive the lower mold 5 and the upper mold 51 to rotate to the middle of the U-shaped frame 1 through the rectangular plates 31, so that the fourth connecting pipe 53 is aligned with the first pipe 13. Then drive the first pipe 13 to slide towards the fourth connecting pipe 53, so that the first pipe 13 is sleeved outside the fourth connecting pipe 53. Connect the first pipe 13 to an external water pipe, inject water into the fourth connecting pipe 53 at the upper end on one side of the lower mold 5 and the upper mold 51, so that the water enters the spiral hole 52 to cool the inside of the mold. The injected water is discharged from the fourth connecting pipe 53 at the lower end on one side of the lower mold 5 and the upper mold 51, so that the water entering the spiral hole 52 is always in a flowing state, which can reduce the scale inside the spiral hole 52. At the same time, drive the arc-shaped strip 2 to slide downwards so that the arc-shaped strip 2 is located on both sides of the lower mold 5 and the upper mold 51. Then connect the external water pipe to the spray nozzle 21 to make the spray nozzle 21 spray water. Drive the arc-shaped strip 2 to drive the spray nozzle 21 to slide downwards, and the spray nozzle 21 sprays water on the outside of the lower mold 5 and the upper mold 51, while cooling the outside of the lower mold 5 and the upper mold 51, solving the problem that scale will be generated after the through holes provided inside the mold are used for a long time, resulting in uneven heat dissipation and affecting the heat dissipation effect of the mold, and the heat dissipation efficiency is relatively low.

[0024] As Figures 5-6As shown, on one side of the U-shaped frame 1, a first L-shaped pipe 11 and a second L-shaped pipe 12 are fixedly connected respectively at positions corresponding to the first pipe 13. The first L-shaped pipe 11 corresponds to the upper end of the spiral hole 52 respectively, and the second L-shaped pipe 12 corresponds to the lower end of the spiral hole 52 respectively. The first pipes 13 are slidably arranged inside the first L-shaped pipe 11 and the second L-shaped pipe 12 respectively. The first L-shaped pipes 11 are fixedly connected with a first connecting pipe 14 together, and the second L-shaped pipes 12 are fixedly connected with a second connecting pipe 141 together.

[0025] Specifically, by driving the first pipe 13 to slide inside the first L-shaped pipe 11 and the second L-shaped pipe 12 to approach the fourth connecting pipe 53 until it is inserted outside the fourth connecting pipe 53, then by introducing water into the first connecting pipe 14, the introduced water enters the fourth connecting pipe 53 at the upper end on one side of the lower mold 5 and the upper mold 51 through the first pipe 13. The introduced water flows along the spiral hole 52, flows to the fourth connecting pipe 53 at the lower end on one side of the lower mold 5 and the upper mold 51, then is discharged into the corresponding first pipe 13, and then is discharged by the second connecting pipe 141. The flowing water enters the spiral hole 52 to cool the inside of the lower mold 5 and the upper mold 51, improving the cooling efficiency and reducing the scale remaining inside the mold.

[0026] As Figure 5 shown, one end of the first connecting pipe 14 away from the first L-shaped pipe 11 is fixedly connected with a first water tank 15, and one end of the second connecting pipe 141 away from the second L-shaped pipe 12 is fixedly connected with a second water tank 16. The first water tank 15 and the second water tank 16 are fixedly connected by a second pipe 17. A filter is arranged in the middle of the second pipe 17. The first water tank 15 is fixedly connected with a bottom plate 4 through a first support frame 151, and the second water tank 16 is fixedly connected to the upper end of the bottom plate 4 through a second support frame 161.

[0027] Specifically, clean water is contained in the first water tank 15. By installing a water pump inside the first water tank 15, the water in the first water tank 15 is controlled to flow into the first L-shaped pipe 11 through the first connecting pipe 14, and then flows into the spiral hole 52 through the first pipe 13. The introduced water flows along the spiral hole 52, flows to the fourth connecting pipe 53 at the lower end on one side of the lower mold 5 and the upper mold 51, then is discharged into the second L-shaped pipe 12 through the first pipe 13, and then is discharged into the second water tank 16 through the second connecting pipe 141. By installing a water pump at the upper end of the second water tank 16, the water in the second water tank 16 enters the second pipe 17. The filter installed inside the second pipe 17 filters the water in the second water tank 16, and the filtered water enters the first water tank 15, realizing the recycling of water resources, saving and being environmentally friendly.

[0028] As Figure 6As shown, a number of the first pipes 13 are commonly fixedly connected to the middle of the first rectangular strip 132. The first rectangular strip 132 is slidably arranged at the lower end of the middle part of the U-shaped frame 1. One side of the first rectangular strip 132 is fixedly connected to the output end of the first electric telescopic rod 133, and the first electric telescopic rod 133 is fixedly connected to the lower end of the middle part of the U-shaped frame 1.

[0029] Specifically, by driving the first electric telescopic rod 133 to contract, the first rectangular strip 132 is driven to approach the fourth connecting pipe 53. The first rectangular strip 132 drives the first pipe 13 to approach the fourth connecting pipe 53 until it is inserted outside the fourth connecting pipe 53. Subsequently, water is introduced into the spiral hole 52 to cool the lower mold 5 and the upper mold 51.

[0030] As Figure 5 shown, conical cylinders 131 are fixedly connected to one end of the first pipe 13 close to the fourth connecting pipe 53.

[0031] Specifically, when driving the first pipe 13 to approach the fourth connecting pipe 53, the first pipe 13 drives the conical cylinder 131 to approach the outside of the fourth connecting pipe 53. The fourth connecting pipe 53 enters the middle of the conical cylinder 131 and then is inserted into the first pipe 13 to prevent jamming.

[0032] As Figure 2 、 Figure 4 shown, the lower end of the cylindrical rod 3 is fixedly connected to the output end of the motor 34. The motor 34 is fixedly connected to the upper end of the bottom plate 4. First cylindrical blocks 33 are respectively arranged at the lower ends of a number of rectangular plates 31 far from the U-shaped frame 1. A circular ring plate 32 is fixedly connected to the lower ends of the first cylindrical blocks 33 together. The four corners of the lower end of the circular ring plate 32 are fixedly connected to the upper end of the bottom plate 4 through second cylindrical blocks 35. The U-shaped frame 1 is fixedly connected to one side of the upper end of the circular ring plate 32. The upper end of the upper mold 51 is fixedly connected to a support plate 54. One side of the lower end of the support plate 54 is fixedly connected to the output end of the second electric telescopic rod 55, and the second electric telescopic rod 55 is fixedly connected to the upper end of the rectangular plate 31.

[0033] Specifically, by starting the motor 34 to drive the cylindrical rod 3 to rotate, the cylindrical rod 3 drives the lower mold 5 and the upper mold 51 at the upper end through the rectangular plate 31 to rotate, which can drive the lower mold 5 and the upper mold 51 to pour alternately. Subsequently, drive the cylindrical rod 3 to rotate to drive the lower mold 5 and the upper mold 51 to rotate to the middle of the U-shaped frame 1 through the rectangular plate 31, and then the lower mold 5 and the upper mold 51 can be cooled.

[0034] As Figure 3 shown, hoses 22 are respectively fixedly connected to the opposite sides of the two arc-shaped strips 2. The inside of the arc-shaped strip 2 is a hollow structure. The hoses 22 are internally connected to the inside of the nozzle 21 through the arc-shaped strip 2, and the hoses 22 are connected to the first water tank 15.

[0035] Specifically, water is put into the first water tank 15 and introduced into the arc-shaped strip 2 through the hose 22, and then sprayed out from the nozzle 21. Subsequently, the arc-shaped strip 2 is driven to drive the nozzle 21 to slide up and down on the sides of the lower mold 5 and the upper mold 51, so as to cool the outsides of the lower mold 5 and the upper mold 51.

[0036] As Figure 7 shown, second rectangular strips 26 are fixedly connected to the opposite sides of the arc-shaped strip 2 respectively. Rectangular cylinders 24 are slidably arranged on the outer sides of the ends of the second rectangular strips 26 far away from the arc-shaped strip 2. First sliding platforms 27 are fixedly connected to the ends of the two rectangular cylinders 24 far away from the second rectangular strips 26 respectively. The first sliding platforms 27 are slidably arranged on one side of the first electric slide rail 271, and the first electric slide rail 271 is fixedly connected to the upper end of the bottom plate 4.

[0037] Specifically, by driving the first sliding platform 27 to slide on one side of the first electric slide rail 271, the first sliding platform 27 drives the second rectangular strip 26 driven by the rectangular cylinder 24 to slide downward through the rectangular cylinder 24, and the second rectangular strip 26 drives the arc-shaped strip 2 to slide on the sides of the lower mold 5 and the upper mold 51, so as to cool the outsides of the lower mold 5 and the upper mold 51.

[0038] As Figure 7 shown, the second rectangular strip 26 is fixedly connected to the inside of the rectangular cylinder 24 through a spring 25. Oblique edge blocks 23 are fixedly connected to both sides of the lower end of the arc-shaped strip 2 respectively, and the two opposite oblique edge blocks 23 are in an inverted V shape.

[0039] Specifically, when the first pipe 13 is inserted outside the fourth connecting pipe 53 to cool the inside of the lower mold 5 and the upper mold 51, then the rectangular cylinder 24 is driven to drive the arc-shaped strip 2 to slide downward through the second rectangular strip 26. At this time, the rectangular plate 31 and the first pipe 13 slide along the oblique edges of the oblique edge blocks 23, so that the distance between the two arc-shaped strips 2 becomes larger. At the same time, the second rectangular strip 26 slides into the rectangular cylinder 24 and compresses the spring 25, so that the two arc-shaped strips 2 slide to the sides of the lower mold 5 and the upper mold 51. Subsequently, the spring 25 releases elastic force, so that the second rectangular strip 26 drives the two arc-shaped strips 2 to approach each other, so that the two arc-shaped strips 2 form a ring, and the distances between each nozzle 21 and the lower mold 5 and the upper mold 51 are the same, and the water spraying is more uniform.

[0040] Embodiment 2: As Figure 6 shown, compared with Embodiment 1, another implementation manner of the present invention is: a cylinder 18 is fixedly connected to the upper end inside the U-shaped frame 1, a third connecting pipe 181 is fixedly connected to one side of the cylinder 18, and the third connecting pipe 181 penetrates through one side of the U-shaped frame 1 and is fixedly connected to the second water tank 16.

[0041] Specifically, the arc-shaped strip 2 drives the nozzle 21 to spray water to cool the outer sides of the lower mold 5 and the upper mold 51. The sprayed water falls into the cylinder 18, and the cylinder 18 collects the sprayed water. The water inside flows into the second water tank 16 along the third connecting pipe 181 for recycling.

[0042] Working principle: When using this cooling device, place the lower mold 5 and the upper mold 51 on the upper end of the rectangular plate 31. Then, pour between the lower mold 5 and the upper mold 51. By starting the motor 34 to drive the cylindrical rod 3 to rotate, the cylindrical rod 3 drives the lower mold 5 and the upper mold 51 at the upper end through the rectangular plate 31 to rotate, which can drive the lower mold 5 and the upper mold 51 to pour alternately. Then, drive the cylindrical rod 3 to rotate and drive the lower mold 5 and the upper mold 51 through the rectangular plate 31 to rotate to the middle of the U-shaped frame 1, so that the fourth connecting pipe 53 is aligned with the first pipe 13. By driving the first electric telescopic rod 133 to contract, drive the first rectangular strip 132 to approach the fourth connecting pipe 53. The first rectangular strip 132 drives the first pipe 13 to approach the fourth connecting pipe 53 until it is inserted outside the fourth connecting pipe 53. There is clean water in the first water tank 15. By installing a water pump inside the first water tank 15, control the water in the first water tank 15 to flow into the first L-shaped pipe 11 through the first connecting pipe 14, and then flow into the spiral hole 52 through the first pipe 13. The introduced water flows along the spiral hole 52, flows to the fourth connecting pipe 53 at the lower end on one side of the lower mold 5 and the upper mold 51, and then is discharged into the second L-shaped pipe 12 through the first pipe 13, and then is discharged into the second water tank 16 through the second connecting pipe 141. By installing a water pump at the upper end of the second water tank 16, make the water in the second water tank 16 enter the second pipe 17. The filter installed inside the second pipe 17 filters the water in the second water tank 16, and the filtered water enters the first water tank 15 to realize the recycling of water resources. The flowing water enters the spiral hole 52 to cool the inside of the lower mold 5 and the upper mold 51; By driving the first sliding table 27 to slide on one side of the first electric slide rail 271, the first sliding table 27 drives the second rectangular strip 26 driven by the rectangular cylinder 24 to slide downward. The second rectangular strip 26 drives the arc-shaped strip 2 to slide on the sides of the lower mold 5 and the upper mold 51. When the rectangular cylinder 24 drives the arc-shaped strip 2 to slide downward through the second rectangular strip 26, at this time, the rectangular plate 31 and the first pipe 13 slide along the hypotenuse of the bevel block 23, so that the distance between the two arc-shaped strips 2 becomes larger. At the same time, the second rectangular strip 26 slides into the rectangular cylinder 24 and compresses the spring 25, so that the two arc-shaped strips 2 slide to the sides of the lower mold 5 and the upper mold 51. Then, the spring 25 releases its elastic force, so that the second rectangular strip 26 drives the two arc-shaped strips 2 to approach each other, so that the two arc-shaped strips 2 form a ring, so that the distances from each nozzle 21 to the lower mold 5 and the upper mold 51 are the same, and the water spraying is more uniform.
