Description

Technical Field

[0001] This invention relates to the field of valve casting technology, specifically to an intelligent cooling device for processing valve castings. Background Technology

[0002] Castings are metal shaped objects obtained by various casting methods. That is, smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, it is processed by grinding and other subsequent means to obtain an object with a certain shape, size and performance. Castings can be classified in many ways: according to the different metal materials used, they are divided into cast steel parts, cast iron parts, cast copper parts, cast aluminum parts, cast magnesium parts, cast zinc parts, cast titanium parts, etc. Each type of casting can be further divided into different categories according to its chemical composition or metallographic structure.

[0003] Currently, in the market, valve casting is sometimes done by workers holding the mold with clamps and moving it under a casting cylinder. The molten metal is then poured into the mold through the casting cylinder. The molten metal is very hot and cannot be cooled directly by water cooling. It needs to be placed on one side and allowed to cool naturally to solidify. However, this method has a long cooling time and low production efficiency. Therefore, to address the above problems, an intelligent cooling device for valve casting is proposed. Summary of the Invention

[0011] As an optional solution for the intelligent cooling equipment for valve casting processing according to the present invention, the vibration assembly includes a fixed frame, a second motor and a rotating disk. The bottom of the fixed frame is fixedly connected to the cooling sand frame. The second motor is fixedly connected inside the fixed frame. The rotating disk is fixedly connected to the end of the main shaft of the second motor. A limit post is fixedly connected to the outside of the rotating disk. A connecting frame is rotatably connected to the outside of the limit post. A rotating frame is rotatably connected to the other end of the connecting frame, and the top of the rotating frame is fixedly connected to the vibration plate.

[0012] As an optional solution for the intelligent cooling equipment for valve casting processing described in this invention, the top of the vibration plate is inclined, and the outer side of the vibration plate is slidably connected to the fixed frame.

[0013] As an optional solution of the intelligent cooling equipment for processing valve castings according to the present invention, wherein: the second motor is provided with limiting sleeves on both sides, the bottom of the limiting sleeve is fixedly connected to the fixed frame, the limiting sleeve is slidably connected to a limiting rod inside, the top of the limiting rod is fixedly connected to the vibration plate, and the fixed frame is fixedly connected to limiting platforms on both sides inside.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In this invention, a cooling sand frame that has been cooled for a period of time is placed inside a placement cylinder. Then, a fourth motor is started to drive the second threaded sleeve to rotate. The rotation of the second threaded sleeve drives the second threaded shaft to move downward, thereby causing the top plate and placement cylinder to move downward. At this time, the cooling sand inside the cooling sand frame covers the outside of the mold, and the cooling sand can cool the mold. At the same time, after a period of cooling, the temperature of the cooling sand on the outside of the mold rises. The fourth motor drives the top plate and placement cylinder to move upward again. The first motor is started to drive the drive gear to rotate. The drive gear drives the driven gear and the transition gear to rotate, thereby causing the rotating shaft to drive the stirring shaft to rotate, which stirs the cooling sand. At this time, the cooler cooling sand next to it can cool the mold again. Compared with the traditional natural static cooling method, this cooling method has a faster temperature rise and fall rate of cooling sand. It can not only continuously circulate the cooling sand for cooling, but also has a fast cooling efficiency. At the same time, the cooling sand pile ensures that even if the molten metal inside the mold drips, it is not easy to cause fire or other situations.

[0018] To ensure the cooling sand continuously covers and cools the mold, a second motor starts and drives a rotating disk to rotate as the mold moves upward. The rotating disk then drives a limit post to rotate, causing the rotating frame and vibrating plate to move up and down under the action of the connecting frame. This agitates the cooling sand. After the cooling sand is agitated, a third motor drives a first threaded shaft to rotate to ensure that the cooling sand covers the outside of the mold again. The rotation of the first threaded shaft drives a first threaded sleeve and an extrusion plate to move, thereby extruding the cooling sand. At the same time, the lower pressure plate and lower pressure block above also extrude cooling sand, thus ensuring the cooling sand cools the mold. Attached Figure Description

[0024] Example 1:

[0025] Please see Figure 1 and Figure 2 The present invention provides a technical solution:

[0026] An intelligent cooling device for processing valve castings includes a cooling sand frame 1, with uniformly distributed guide cylinders 12 fixedly connected to the bottom of the cooling sand frame 1, a placement cylinder 11 slidably connected inside the guide cylinder 12, and a top plate 14 fixedly connected to the bottom of the placement cylinder 11.

[0027] The aforementioned placement cylinder 11 has a mold 10 inside, and pads 13 are fixedly connected to both sides of the top of the aforementioned placement cylinder 11. A rotating shaft 6 is provided between the aforementioned placement cylinders 11, and an agitator 7 is fixedly connected to the outside of the aforementioned rotating shaft 6.

[0028] A first motor 2 is fixedly connected to the front side of the cooling sand frame 1. A drive gear 3 is fixedly connected to the end of the main shaft of the first motor 2. A driven gear 4 meshes with the outside of the drive gear 3. A transition gear 5 meshes with the other side of the driven gear 4. The inner sides of the driven gear 4 and the transition gear 5 are fixedly connected to the rotating shaft 6. The outer side of the rotating shaft 6 is rotatably connected to the cooling sand frame 1. Vibration components 8 and extrusion components 9 are provided on both sides of the cooling sand frame 1.

[0029] The cooling sand frame 1 has a base plate 18 at its bottom. A fourth motor 17 is fixedly connected inside the base plate 18. A second threaded sleeve 16 is fixedly connected to the end of the main shaft of the fourth motor 17. A second threaded shaft 15 is screwed to the outside of the second threaded sleeve 16. A top plate 14 is fixedly connected to the top of the second threaded shaft 15. Telescopic rods 19 are provided on both sides of the second threaded shaft 15. The top of the telescopic rods 19 is fixedly connected to the top plate 14, and the bottom of the telescopic rods 19 is fixedly connected to the base plate 18. The telescopic rods 19 ensure that the top plate 14 slides up and down stably.

[0030] When in use, the power is connected. Traditional methods of casting valve parts cannot easily achieve proper cooling with water, as this can lead to poor casting quality. Natural cooling is generally used, but this method is inefficient. This device, however, places the cast mold 10 inside the placement cylinder 11, supported by a pad 13. The fourth motor 17 is activated, rotating the second threaded sleeve 16. The second threaded sleeve 16 then moves the second threaded shaft 15 downwards, which in turn moves the top plate 14 and the placement cylinder 11 downwards. This downward movement of the placement cylinder 11 moves the cast mold 10 downwards, and, in conjunction with the extrusion assembly 9 and the lower pressure plate 23, cools it down. The cooling sand is in close contact with the mold 10. At this time, the cooling sand is used to exchange heat with the mold 10 to quickly cool the mold 10. After cooling, the temperature of the cooling sand on the outside of the mold 10 is relatively high. The mold 10 is moved upward by the fourth motor 17, which drives the second threaded sleeve 16 to rotate. The second threaded sleeve 16 drives the second threaded shaft 15 to move upward. The second threaded shaft 15 drives the top plate 14 and the placement cylinder 11 to move upward. Then, the first motor 2 is started to drive the drive gear 3 to rotate, which in turn causes the driven gear 4 and the transition gear 5 to rotate. This causes the rotating shaft 6 and the stirring shaft 7 to rotate, thereby stirring the cooling sand and mixing the higher-temperature cooling sand with the lower-temperature cooling sand to reduce its temperature and facilitate subsequent continuous use.

[0031] Example 2

[0032] This embodiment is an improvement made to Implementation 1. Please refer to [link / reference]. Figure 1 and Figure 2 Specifically, the cooling sand frame 1 is fixedly connected to both sides of the side rods 20, the side rods 20 are fixedly connected to the top of the sliding cylinder 21, the top of the sliding cylinder 21 is fixedly connected to the hydraulic rod 22, the output shaft of the hydraulic rod 22 is fixedly connected to the horizontally arranged lower pressure plate 23, and the bottom of the lower pressure plate 23 is fixedly connected to the lower pressure block 24.

[0033] The hydraulic rod 22 drives the lower pressure plate 23 to move downward, and the lower pressure plate 23 drives the lower pressure block 24 to move downward, thus squeezing the cooling sand between the molds 10. At this time, the cooling sand is brought back into close contact with the molds 10, which is used to quickly cool the molds 10.

[0034] Example 3

[0035] This embodiment is an improvement upon the two implementation examples. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 Specifically, the aforementioned vibration assembly 8 includes a fixed frame 801, a second motor 802, and a rotating disk 803. The bottom of the fixed frame 801 is fixedly connected to the cooling sand frame 1. The second motor 802 is fixedly connected inside the fixed frame 801. The rotating disk 803 is fixedly connected to the end of the main shaft of the second motor 802. A limit post 804 is fixedly connected to the outside of the rotating disk 803. A connecting frame 805 is rotatably connected to the outside of the limit post 804. A rotating frame 806 is rotatably connected to the other end of the connecting frame 805, and the top of the rotating frame 806 is fixedly connected to the vibration plate 807.

[0036] The top of the aforementioned vibrating plate 807 is inclined, and the outer side of the aforementioned vibrating plate 807 is slidably connected to the fixed frame 801. This arrangement ensures that the cooling sand slides automatically above the vibrating plate 807, while the vibrating plate 807 is in close contact with the inner side of the fixed frame 801, preventing the cooling sand from entering the interior of the fixed frame 801 and affecting the normal use of the equipment.

[0037] The second motor 802 is provided with limiting sleeves 810 on both sides. The bottom of the limiting sleeve 810 is fixedly connected to the fixed frame 801. The limiting sleeve 810 is slidably connected to the limiting rod 809 inside. The top of the limiting rod 809 is fixedly connected to the vibration plate 807. The fixed frame 801 is fixedly connected to the limiting platform 808 on both sides inside. The limiting sleeves 810 and the limiting rod 809 are used to ensure that the vibration plate 807 moves up and down stably.

[0038] When it is necessary to agitate the cooling sand, a portion of the cooling sand can be agitated under the action of the rotating shaft 6 and the agitating shaft 7. The cooling sand on both sides can be driven to rotate by starting the second motor 802 to rotate the rotating disk 803. Under the action of the limiting column 804 and the connecting frame 805, the rotating frame 806 and the vibrating plate 807 can slide back and forth. At this time, the cooling sand on both sides of the cooling sand frame 1 can be vibrated, which facilitates the mixing of cooling sand with different temperatures for cooling and facilitates the subsequent cooling effect.

[0039] Example 4

[0040] This embodiment is an improvement upon the three implementation examples. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 4 , specifically

[0041] The extrusion assembly 9 includes an extrusion frame 901, a third motor 902, and a first threaded shaft 903. The outer side of the extrusion frame 901 is fixedly connected to the cooling sand frame 1. The third motor 902 is fixedly connected inside the extrusion frame 901. The end of the main shaft of the third motor 902 is fixedly connected to the first threaded shaft 903. The outer side of the first threaded shaft 903 is screwed with a first threaded sleeve 904. The other end of the first threaded sleeve 904 is fixedly connected to an extrusion plate 905. The outer side of the extrusion plate 905 is slidably connected to the extrusion frame 901.

[0042] The first threaded sleeve 904 is provided with guide posts 906 on both sides. One end of the guide post 906 is fixedly connected to the extrusion plate 905. A guide sleeve 907 is slidably connected inside the guide post 906. The other end of the guide sleeve 907 is fixedly connected to the extrusion frame 901. The guide posts 906 and guide sleeves 907 are provided to ensure the stable sliding of the extrusion plate 905 and to ensure that the outer side of the extrusion plate 905 is in close contact with the extrusion frame 901. This prevents cooling sand from entering the extrusion frame 901 and ensures the normal operation of the equipment.

[0043] As the mold 10 moves upward, the cooling sand is agitated by the stirring device, causing the higher-temperature cooling sand to mix with the lower-temperature cooling sand, resulting in a temperature drop. At this point, the mold 10 moves back down into the interior of the cooling sand, but the outer side of the mold 10 cannot make close contact with the cooling sand, resulting in poor cooling effect. To restore close contact between the cooling sand and the mold 10, the third motor 902 is activated to rotate the first threaded shaft 903. The first threaded shaft 903 moves the first threaded sleeve 904, which in turn moves the extrusion plate 905 to extrude the cooling sand. This ensures that the cooling sand makes full contact with the outside of the mold 10, thereby rapidly cooling the mold 10. This cooling method allows for continuous cooling because the cooling sand heats up and cools down very quickly. Furthermore, the accumulation of cooling sand ensures that even if the molten metal inside the mold drips, it is less likely to cause a fire.
