Description

A hydrostatic molding production line with a jacket cooling function Technical Field

[0001] This invention relates to the field of static pressure molding line equipment, specifically a static pressure molding production line with a cooling box function. Background Technology

[0002] The static pressure molding line is a shorthand for the fully automated molding equipment production line in clay sand casting. It is a fully automated molding line with a mold box, which is highly efficient and produces good sand mold quality. It mainly consists of molding station, core lowering and mold closing station, pouring and cooling station, and sand dropping station. It includes the static pressure molding main machine, molding auxiliary machine, mold conveyor, electro-hydraulic system, and process equipment such as sand box and mold frame.

[0003] After the casting is poured into the sand box, it is necessary to wait for the casting to cool down before removing it from the sand box. In order for the sand box to cool down during the production process, the static pressure molding line is equipped with a cooling circulation line. The longer the sand box travels on the cooling circulation line, the greater the cooling effect. Due to the limited space of the equipment, the distance of the cooling circulation line is generally short. If the cooling time of the casting is required to be longer, it needs to travel several more times on the cooling circulation line. This will affect the subsequent production of castings on the entire production line and the cooling and transfer of the sand box, thus reducing the production efficiency of the casting. Summary of the Invention

[0004] The purpose of this invention is to provide a static pressure molding production line with a sleeve cooling function. A sleeve cooling line and a sand box and sleeve transfer device are added on the upper side of the original sand box cooling circulation line. Under the premise of achieving the required cooling time, it will not affect the subsequent casting production and sand box cooling transfer of the entire production line. At the same time, it saves the floor space of the production line, reduces investment costs, and solves the problems in the prior art.

[0020] The static pressure molding production line with a cooling box function described in this invention, as shown in Figures 1-3, includes a static pressure molding casting production line 1, a sand box return line 2, a sand box cooling line 3, a first cooling box line 4, a second cooling box line 5, and a casting conveying mechanism 6. The static pressure molding casting production line 1 is used to manufacture sand molds and pour castings. The sand box cooling line 3 carries a sand box 10 containing castings and cools it down. The first cooling box line 4 and the second cooling box line 5 carry a cooling box containing castings and cool it down. The casting conveying mechanism 6 removes the cooled castings and transports them to other workstations. The static pressure molding casting production line 1 can be the static pressure molding machine described in Chinese Patent Publication No. CN204094072U.

[0021] To minimize the footprint of the cooling lines in the overall device, the sand box cooling line 3, the first set of cooling lines 4, and the second set of cooling lines 5 are arranged vertically in layers. The first set of cooling lines 4 and the second set of cooling lines 5 are located above the sand box cooling line 3, and the sand box return line 2 is located below the first set of cooling lines 4 and the second set of cooling lines 5.

[0022] To transfer sand boxes 10 from the sand box return line 2 to the sand box cooling line 3, the sand box inlet of the sand box return line 2 is connected to the sand box cooling line 3 via a sand box cooling transfer vehicle 7. To transfer the sleeved box 12 from the first sleeved box cooling line 4 to the second sleeved box cooling line 5, the sleeved box inlet and outlet of the first sleeved box cooling line 4 are connected to the second sleeved box cooling line 5 via sleeved box cooling transfer vehicles 8. The aforementioned sand box cooling transfer vehicle 7 and sleeved box cooling transfer vehicle 8 can be the transfer device for sand box transfer described in Chinese Patent Publication No. CN206643341U.

[0023] Sand box traveling trolleys 9 are installed on the sand box return line 2 and the sand box cooling line 3. The sand box traveling trolleys 9 can travel sequentially on the return line and the cooling line. Sand boxes 10, containing molding sand and castings, are installed on the sand box traveling trolleys 9. Set-top cooling trolleys 11 are installed on the first set-top cooling line 4 and the second set-top cooling line 5. Set-top cooling trolleys 11 can travel sequentially on the set-top cooling line. Set-top cooling trolleys 11 are installed on the set-top cooling trolleys 11, containing molding sand and castings.

[0024] Chain conveyors or conveyor belts can be installed on the sand box return line 2, sand box cooling line 3, first set box cooling line 4, and second set box cooling line 5. By setting positioning cards, they can be connected to the traveling trolley. When the drive motor starts, the sand box 10 and the set box 12 can move sequentially on the conveyor line.

[0025] In order to facilitate the transfer of castings from sand box 10 to sleeve box 12, sleeve box 12 is a box with openings at both the top and bottom. In this way, castings in sand box 10 at a lower position can be pushed upward into sleeve box, and castings in sleeve box 12 can be pushed downward to complete the sand removal and part retrieval.

[0026] To facilitate the transfer of castings between the sand box 10 and the casing 12, as well as between various cooling lines and transfer lines, a primary sand box removal assembly 13 is installed between the sand box return line 2, the first casing cooling line 4, and the casting conveying mechanism 6. The primary sand box removal assembly 13 can send the molding sand and castings from the sand box 10 on the sand box return line 2 into the casing 12, and then transfer them to the first casing cooling line 4 for cooling. It can also send the molding sand and castings sent into the casing 12 into the casting conveying mechanism 6.

[0027] A secondary casting conveyor assembly 14 is installed between the first set of cooling line 4 and the casting conveyor mechanism 6. The secondary casting conveyor assembly 14 can feed the castings in the first set of cooling line 4 onto the casting conveyor mechanism 6. The casting conveyor mechanism 6 can be an existing sand removal machine and conveyor, which can realize the sand removal, picking up and transfer of castings.

[0028] As shown in Figure 4, the primary box-breaking machine assembly 13 includes a first fixed frame 15, which spans the first box cooling line 4, the sand box return line 2, and the casting conveying mechanism 6. A horizontally arranged first box support plate 16 is installed within the first fixed frame 15. One end of the first box support plate 16 is connected to the first box cooling line 4, and the other end is located above the casting conveying mechanism 6. The box 12 can move on the first box support plate 16 and transfer between the first box cooling line 4, the sand box return line 2, and the casting conveying mechanism 6.

[0029] The first set of box support plate 16 above the sand box return line 2 is provided with a molding sand inlet 17. The first set of box support plate 16 above the casting conveying mechanism 6 is provided with a first casting drop port 18. The bottom of the molding sand inlet 17 is equipped with a first box pusher 19 that can push upward. The first fixed frame 15 between the first box pusher 19 and the sand box return line 2 is equipped with a sand box grabbing and transferring device 20. The sand box grabbing and transferring device 20 can transfer the sand box 10 on the sand box return line 2 to the first box pusher 19. The first box pusher 19 can push the molding sand in the sand box 10 into the set of box 12.

[0030] The above process of the first box-pushing machine 19 pushing the molding sand in the sand box 10 into the sleeve box 12 is as follows: The sleeve box grabbing and transfer device 41 of the first box-pushing machine assembly 13 transfers an empty sleeve box 12 from the first sleeve box cooling line 4 to the molding sand inlet 17. Then the first box-pushing machine 19 pushes the molding sand in the sand box 10 into the sleeve box 12. Then the sleeve box grabbing and transfer device 41 transfers this sleeve box 12 to the first sleeve box cooling line 4 to participate in the sleeve box cooling line circulation.

[0031] A first cleaning mechanism 21 capable of being pushed downwards is installed on the first fixed frame 15 above the first casting drop port 18. The first cleaning mechanism 21 can clean the loose sand on the inner wall of the casing 12 and push the casting inside the casing 12 onto the casting conveying mechanism 6. A casing gripping and transferring device 41 is also installed on the first fixed frame 15. The casing gripping and transferring device 41 can transfer the casing 12 on the first casing cooling line 4 to the bottom of the first cleaning mechanism 21, and can also transfer the casing 12 containing the casting on the first casing support plate 16 to the first casing cooling line 4.

[0032] As shown in Figure 5, the secondary box-opening machine assembly 14 includes a second fixed frame 22, which spans the first box cooling line 4 and the casting conveying mechanism 6. A horizontally arranged second box support plate 23 is installed within the second fixed frame 22. One end of the second box support plate 23 is connected to the first box cooling line 4, and the other end is located above the casting conveying mechanism 6. The box 12 can move on the second box support plate 23 and transfer between the first box cooling line 4 and the casting conveying mechanism 6.

[0033] The casting conveying mechanism 6 has a second casting drop opening 42 on the second casing support plate 23 on its upper side. A second cleaning mechanism 24, capable of being pushed downwards, is installed on the second fixing frame 22 above the second casting drop opening 42. The second cleaning mechanism 24 can clean the loose sand from the inner wall of the casing 12 and push the castings inside the casing 12 onto the casting conveying mechanism 6. A casing gripping and transferring device 41 is also installed on the second fixing frame 22. The casing gripping and transferring device 41 can transfer the casing 12 on the first casing cooling line 4 to the bottom of the second cleaning mechanism 24.

[0034] The casing gripping and transferring device 41 and the sand box gripping and transferring device 20 can be existing gripping robots or clamping hydraulic cylinder mechanisms. When gripping and fixing the sand box 10 or casing 12, they can also move together to realize the transfer of the sand box 10 and casing 12. The first box-pushing machine 19 can be the box-pushing machine described in Chinese Patent Publication No. "CN201105318Y", which realizes the upward lifting or downward pushing of the molding sand and castings inside the casing 12 through the vertical lifting and lowering of the hydraulic cylinder.

[0035] The first cleaning mechanism 21 and the second cleaning mechanism 24 can be vertically moving parts equipped with cleaning devices, which can clean the inner wall of the casing. When the casing moves to the casting drop position, the casting inside can be removed by sand falling under the action of gravity. The first cleaning mechanism 21 and the second cleaning mechanism 24 can not only clean the floating sand on the inner wall of the casing, but also have the function of punching the casing to remove the casting, ensuring that the casting can be removed by sand falling at the casting drop position.

[0036] When using the static pressure molding production line with a cooling box function described in this invention for casting production, the static pressure molding casting production line 1 first completes the molding in an empty sand box, and then completes the pouring of molten iron. The sand box 10 containing the casting is then transferred via a sand box cooling transfer car 7 to the sand box cooling line 3 for cooling. Afterwards, the sand box cooling transfer car 7 transfers it to the first-stage box-pushing machine assembly 13. If the cooling reaches the specified temperature, the sand box gripping and transferring device 20 transfers the sand box 10 containing the casting to the first box-pushing machine 19. The first box-pushing machine 19 pushes the molding sand and casting inside the sand box 10 upwards into the cooling box 12. Driven by the cooling box gripping and transferring device 41, the cooling box 12 is transferred to the bottom of the first cleaning mechanism 21. The first cleaning mechanism 21 then pushes the casting inside the cooling box downwards onto the casting conveying mechanism 6, completing the sand removal and casting retrieval operation.

[0037] If the cooling temperature does not reach the specified temperature when the sand box is transferred to the first-stage mold box assembly 13, the sand box grabbing and transferring device 20 transfers the sand box 10 containing the casting to the first mold box machine 19. The first mold box machine 19 pushes the molding sand and casting inside the sand box 10 upward into the sleeve box 12. The sleeve box grabbing and transferring device 41 transfers the sleeve box 12 containing the casting to the first sleeve box cooling line 4, and after being transferred by the sleeve box cooling transfer car 8, the sleeve box 12 containing the casting moves to the second sleeve box. The castings are cooled on the cooling line 5 and then transferred to the secondary box-breaking machine assembly 14 by the cooling transfer car 8. The box-breaking machine assembly 14 uses a box-breaking gripping and transfer device 41 to grab the box and transfer it to the bottom of the second cleaning mechanism 24. The second cleaning mechanism 24 is activated to push the castings in the box downwards onto the casting conveying mechanism 6, completing the sand removal and part retrieval operation. The above operation has a longer cooling and cooling travel distance and is suitable for casting products with longer cooling times.

[0038] Furthermore, in order to facilitate the separation between the box 12 and the box traveling trolley 11 when the box grabbing and transferring device 41 is activated, as shown in Figures 6, 7 and 8, the box grabbing and transferring device 41 includes a movable frame 25, which can move on the upper side of the box support plate. The movable frame 25 can be a movable plate with movable wheels or a gantry frame, which can move on a fixed frame.

[0039] To achieve clamping and fixing of the sleeve 12, sleeve clamping mechanisms are installed on both sides of the bottom length direction of the movable frame 25. The sleeve clamping mechanism includes a connecting frame 26, with two rows of horizontally arranged clamping wheels 27 on the inner side of the connecting frame 26. The side of the sleeve 12 is provided with clamping plates 28 that cooperate with the clamping wheels 27. The clamping plates 28 are horizontally arranged, and guide ramps 40 are provided at both ends of the clamping plates 28 in the length direction. A horizontally arranged clamping cylinder 29 is also installed on the connecting frame 26, and clamping holes 30 that cooperate with the clamping cylinder 29 are opened on the side of the sleeve 12.

[0040] When the case 12 is moved on the first case cooling line 4 on the case traveling trolley 11, the piston rod of the clamping cylinder 29 on the case clamping mechanism located in the fixed frame retracts. As the case 12 gradually enters the case clamping mechanism, the guide ramp 40 first contacts the two rows of clamping wheels 27. While the case traveling trolley 11 moves the case 12, the case 12 gradually moves upward. When the clamping plate 28 enters between the two rows of clamping wheels 27, the case 12 moves upward and separates from the case traveling trolley 11. The case traveling trolley 11 continues to move on the first case cooling line 4, and the case 12 is clamped by the case clamping mechanism. Subsequently, the piston rod of the clamping cylinder 29 extends and enters the clamping hole 30, and the case 12 is locked by the clamping mechanism. The case grabbing and transferring device 41 can then drive the case 12 to perform subsequent transfer operations.

[0041] Furthermore, to achieve stable ejection of the castings inside the casing by the ejector, as shown in Figure 9, the first ejector 19 includes a first mounting base 31 mounted on a first fixed frame 15. An ejector cylinder 32 is mounted on the first mounting base 31. An ejector plate 33 is mounted on the upper end of the piston rod of the ejector cylinder 32. A first guide rod 34 is mounted on the ejector plate 33. A first guide sleeve 35, which cooperates with the first guide rod 34, is mounted on the first mounting base 31. When the piston rod of the ejector cylinder 32 pushes upward, it drives the ejector plate 33 to move upward, pushing the castings inside the sand box into the casing.

[0042] Furthermore, in order to enable the cleaning mechanism to clean the floating sand inside the housing 12 while also assisting in the removal of sand-laden parts, as shown in Figure 10, both the first cleaning mechanism 21 and the second cleaning mechanism 24 include a second mounting base 43 mounted on a fixed frame. The second mounting base 43 is equipped with a cleaning cylinder 44. A cleaning plate 45 is mounted on the lower end of the piston rod of the cleaning cylinder 44. A second guide rod 46 is provided on the cleaning plate 45. A second guide sleeve 47 that cooperates with the second guide rod 46 is provided on the second mounting base 43.

[0043] The cleaning plate 45 is matched with the opening and gradually descending position of the sleeve 12. The piston rod of the cleaning cylinder 44 is arranged downward. The cleaning plate 45 is pushed downward, which can clean the floating sand on the inner wall of the sleeve 12 and also assist in the removal of castings from the sand.

[0044] Furthermore, in order to allow the sand box 10 containing the casting to circulate back and forth on the sand box cooling line 3 to achieve the cooling requirement, as shown in Figure 11, the sand box cooling line 3 is arranged in several rows side by side. Each row of the sand box cooling line 3 is equipped with a conveyor line, which can drive the sand box 10 to move sequentially, allowing the sand box 10 to move from one end of the sand box cooling transfer car 7 to the other end of the sand box cooling transfer car 7. The sand box cooling transfer cars 7 at both ends of the length direction of the sand box cooling line 3 include a first light rail 36, a sand box transfer car body 37, and a sand box pushing buffer cylinder 48. The piston rod of the buffer cylinder 48 extends to push the sand box 10 on the first light rail 36 into the sand box cooling line 3, and can also push the sand box 10 on the sand box cooling line 3 into the sand box transfer car body 37 on the other end of the first light rail 36. The sand box transfer car body 37 can transfer and exchange the sand boxes 10 on each row of sand box cooling lines 3, and can also transfer the sand box 10 between the sand box cooling line 3 and the sand box return line 2. When the castings on it reach the cooling requirements, the sand box cooling transfer car 7 will transfer the sand box 10 containing the castings to the sand box return line 2 to facilitate subsequent transfer and sand removal operations.

[0045] The above operation process is as follows: The sand box return line 2 and the sand box cooling line 3 are connected by sand box cooling transfer cars 7 set at both ends of the length direction to carry out the sand box transfer cycle. The sand box cooling transfer cars 7 transfer the sand box 10 after pouring molten iron to each row of cooling lines of the sand box return line 2 and the sand box cooling line 3 in turn. After cooling, the sand box 10 enters the sand box cooling transfer car 7 on the other side of the cooling line in turn. The sand box cooling transfer car 7 transfers the cooled sand box 10 to the sand box return line 2 to prepare for entering the first-stage box-opening machine assembly 13.

[0046] The sand box cooling transfer vehicles 7 at both ends of the sand box cooling line have similar structures. They are equipped with a first light rail 36, a sand box transfer vehicle body 37, and a sand box pushing buffer cylinder 48. The sand box pushing buffer cylinder 48 of one side of the sand box cooling transfer vehicle 7 extends to push the sand box 10 stopped on the first light rail 36 into the cooling line. Several cooling lines can be pushed in sequence. The sand box cooling transfer vehicle 7 on the other side stops at the corresponding cooling line to receive the sand box 10 pushed out from the cooling line. The sand box 10 completes the cooling work.

[0047] Furthermore, in order to allow the casting-containing box 12 to circulate back and forth on the second box cooling line 5 to achieve the cooling requirement, as shown in Figure 12, the second box cooling line 5 is arranged in several rows side by side. Each row of the second box cooling line 5 is equipped with a conveyor line, which can drive the box 12 to move sequentially, allowing the box 12 to move from the box cooling transfer car 8 at one end of the second box cooling line 5 to the box cooling transfer car 8 at the other end. The box cooling transfer cars 8 at both ends of the length direction of the second box cooling line 5 include a second light rail 38, a box transfer car body 39, and a box pushing buffer cylinder 49. The piston rod of the buffer cylinder 49 extends to push the housing 12 on the second light rail 38 into the second housing cooling line 5, and can also push the housing 12 on the second housing cooling line 5 into the housing transfer car 39 on the second light rail 38. The housing transfer car 39 can transfer and exchange the housings 12 on each row of the second housing cooling line 5, and can also transfer the housings 12 between the second housing cooling line 5 and the first housing cooling line 4. When the castings on it reach the cooling requirements, the housing cooling transfer car 8 will transfer the housing 12 containing the castings to the first housing cooling line 4 to facilitate subsequent transfer and sand removal operations.

[0048] The above operation process is as follows: The first and second box cooling lines 4 and 5 operate in a cyclical manner by box cooling transfer vehicles 8 at both ends along their length. One box cooling transfer vehicle 8 pushes the box 12 to be cooled into the first box cooling line 4, while the other box cooling transfer vehicle 8 stops at the other end of the first box cooling line 4 to receive the box 12 pushed off the first box cooling line 4. The box cooling transfer vehicle 8 on one side sequentially transfers the box 12 to each row of cooling lines on the second box cooling line 5. After cooling, the box 12 sequentially enters the box cooling transfer vehicle 8 on the other side of the cooling line, where it transfers the cooled box 12 back to the first box cooling line 4 to prepare for entering the secondary box unpacking machine assembly 14.
