Description

Technical Field

[0001] This utility model relates to the field of casting mold technology, and specifically to a casting mold cooling mechanism. Background Technology

[0002] Casting molds are used to obtain the structural shape of parts. The structural shape of the part is made in advance using other easily formable materials. Then, the mold is placed in the sand mold to form a cavity with the same structural dimensions as the part. A fluid liquid is then poured into the cavity. After the liquid cools and solidifies, a part with the exact same shape and structure as the mold is formed. It is widely used in automobiles, power, ships, rail transportation and other fields.

[0003] Patent No. 202122120344.4 discloses a casting mold with a cooling mechanism, which effectively improves the cooling rate compared to the traditional natural cooling method.

[0004] However, existing casting molds with cooling mechanisms rely on structures such as a second water pipe, a first connecting pipe, and a telescopic pipe to cool the upper and lower molds. After the upper and lower molds have cooled, workers need to manually remove and disassemble the round pipes, which is cumbersome and inconvenient for removing the molded workpieces from the upper and lower molds. At the same time, the heat-conducting plate outside the water tank is always exposed to the external environment, and external objects are prone to collision with the heat-conducting plate, which is easily damaged. Therefore, a casting mold cooling mechanism is needed. Utility Model Content

[0005] The main purpose of this utility model is to provide a casting mold cooling mechanism. This utility model solves the problems of existing casting molds with cooling mechanisms, such as the inconvenience of removing the workpieces formed in the upper and lower molds and the inconvenience of protecting the heat-conducting plate outside the water tank, by setting up a protective plate A, a protective plate B, a two-way lead screw, a two-way threaded rod, a motor, a cooling rack A, and a cooling rack B.

[0006] The technical solution adopted by this utility model to solve its technical problem is a casting mold cooling mechanism, including an upper mold and a lower mold. A fixing frame supporting the lower mold is bolted to the bottom of the lower mold. A servo motor providing power is bolted inside the fixing frame, and a bidirectional threaded rod is keyed to the power output end of the servo motor. A threaded sleeve A and a threaded sleeve B are threadedly connected to the outside of the bidirectional threaded rod, with threaded sleeve A located to the left of threaded sleeve B. A drive plate A is snapped onto the outside of threaded sleeve A, and a cooling rack A for cooling the upper and lower molds is welded to the outside of drive plate A. The threaded sleeve B is snapped onto the outside of... There is a drive plate B, and a cooling rack B for cooling the upper and lower molds is welded to one side of the drive plate B. A heat-conducting layer for heat transfer on the upper and lower molds is bonded to the inner side of the cooling rack A and the cooling rack B. A gear A is sleeved on the outer side of the bidirectional threaded rod, and a synchronous belt is meshed with the outer side of the gear A. A gear B is meshed with the inner side of the synchronous belt away from the gear A, and a bidirectional lead screw is snapped into the inner side of the gear B. A threaded sleeve A and a threaded sleeve B are threaded to the outer side of the bidirectional lead screw, and the threaded sleeve A is located to the left of the threaded sleeve B. A protective plate A is welded to the outer side of the threaded sleeve A, and a protective plate B is welded to the outer side of the threaded sleeve B.

[0007] By adopting the above technical solution, after the upper and lower molds have cooled down, the servo motor in the fixed frame is driven by the external controller to rotate the bidirectional threaded rod. The threaded sleeves A and B outside the bidirectional threaded rod are both limited by the external structure and move laterally in opposite directions outside the bidirectional threaded rod. Then, the threaded sleeve A drives the drive plate A to move, and the threaded sleeve B drives the drive plate B. Subsequently, the drive plate A drives the cooling rack A to separate from the upper and lower molds, and the drive plate B drives the cooling rack B to separate from the upper and lower molds. This makes it easy to remove the workpieces formed in the upper and lower molds, and also makes it easy to inspect the upper and lower molds.

[0008] When protective frames A and B are moved out of the upper and lower molds, gear A, which is screwed on the outside of the double-threaded rod, drives the synchronous belt to rotate. Then, the synchronous belt drives the double-threaded rod, which is screwed on the inside of gear B, to rotate. Then, threaded sleeves A and B outside the double-threaded rod are limited by the external structure and move laterally towards each other outside the double-threaded rod. Then, threaded sleeve A drives protective plate A to move, and threaded sleeve B drives protective plate B to move, so that protective plates A and B move to the outside of the heat-conducting plate outside the water tank, thus facilitating the protection of the heat-conducting plate.

[0009] Specifically, a base frame is welded to the bottom of the fixed frame, and a water tank for holding cooling water is fixed to the inside of the base frame with screws. A heat-conducting plate for heat dissipation inside the water tank is fixed to the outside of the water tank with screws. A branch pipe is inserted into the bottom of the water tank, and a pump body is fixed to the end of the branch pipe away from the water tank with screws. A connecting pipe is fixed to one side of the pump body with screws, and a conveying box is fixed to the end of the connecting pipe away from the pump body with screws. Fixed pipe A and fixed pipe B are symmetrically inserted into the outside of the conveying box, and fixed pipe A is located to the left of fixed pipe B.

[0010] By adopting the above technical solution, when the upper mold and lower mold need to be cooled, the pump body outside the fixed frame is controlled by an external controller to transport water from the water tank to the pump body through a branch pipe. Then, the connecting pipe on one side of the pump body transports water to the conveying box. Subsequently, the fixed pipe A outside the conveying box transports water to the cooling rack A, and the fixed pipe B outside the conveying box transports water to the cooling rack B. The cooling cavities in the cooling rack A and the cooling rack B are both curved, which extends the contact time between the cooling water and the upper mold and the lower mold, thereby facilitating the cooling treatment of the upper mold and the lower mold. In addition, the fixed pipe A, the fixed pipe B and the return pipe are all retractable corrugated pipes.

[0011] Both ends of the bidirectional lead screw and the end of the bidirectional threaded rod furthest from the servo motor are fitted with bearings with interference fit.

[0012] Specifically, the end of the fixed pipe A away from the conveying box is connected to the top of the cooling rack A with a screw, and the end of the fixed pipe B away from the conveying box is connected to the top of the cooling rack B with a screw. Both the cooling rack A and the cooling rack B have return pipes inserted at their bottoms to allow water to flow back to the water tank.

[0013] By adopting the above technical solution, after cooling racks A and B cool the upper and lower molds, the water in cooling racks A and B flows into the water tank through the return pipe inserted at the bottom, thereby improving the utilization rate of water resources.

[0014] Specifically, the top of the upper mold is provided with an injection port for material to enter the upper mold and the lower mold.

[0015] By adopting the above technical solution, the injection port set at the top of the upper mold allows the material to enter the upper mold and the lower mold.

[0016] Specifically, both the protective plate A and the protective plate B are welded to the outside of the sleeves, and the inner side of the sleeves is slidably connected to the support rods.

[0017] By adopting the above technical solution, when protective plate A and protective plate B move, the external welded supports of protective plate A and protective plate B slide outside the support rods fixed with screws inside the base frame, thereby improving the stability of the movement of protective plate A and protective plate B.

[0018] Specifically, the input terminals of both the pump body and the servo motor are electrically connected to the power supply terminal of an external power source.

[0019] By adopting the above technical solution and connecting to an external power source, the electrical equipment can operate normally.

[0020] The beneficial effects of this utility model are:

[0021] (1) The casting mold cooling mechanism of this utility model, after the upper mold and the lower mold are cooled, the servo motor in the fixed frame is driven by the external controller to rotate the bidirectional threaded rod. The threaded sleeve A and the threaded sleeve B outside the bidirectional threaded rod are both limited by the external structure and move laterally in opposite directions outside the bidirectional threaded rod. Then the threaded sleeve A drives the drive plate A to move, and the threaded sleeve B drives the drive plate B. Subsequently, the drive plate A drives the cooling rack A to separate from the upper mold and the lower mold, and the drive plate B drives the cooling rack B to separate from the upper mold and the lower mold, so as to facilitate the removal of the workpiece formed in the upper mold and the lower mold, and at the same time, to facilitate the maintenance of the upper mold and the lower mold.

[0022] (2) In the casting mold cooling mechanism described in this utility model, when the protective frame A and the protective frame B are moved out of the upper mold and the lower mold, the gear A connected to the screw sleeve outside the double-threaded rod drives the synchronous belt to rotate. Then the synchronous belt drives the double-threaded rod connected to the screw inside the gear B to rotate. Then the thread sleeve A and the thread sleeve B outside the double-threaded rod are limited by the external structure and move laterally towards each other outside the double-threaded rod. Then the thread sleeve A drives the protective plate A to move, and the thread sleeve B drives the protective plate B to move, so that the protective plate A and the protective plate B move to the outside of the heat-conducting plate outside the water tank, thereby facilitating the protection of the heat-conducting plate.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] In order to remove the workpiece formed in the upper mold 6 and the lower mold 7, as an embodiment of this utility model, such as... Figure 1 , Figure 2 and Figure 3 As shown, the casting mold cooling mechanism of this utility model includes an upper mold 6 and a lower mold 7. A fixing frame 15 supporting the lower mold 7 is bolted to the bottom of the lower mold 7. A servo motor 20 providing power is bolted inside the fixing frame 15, and a bidirectional threaded rod 17 is keyed to the power output end of the servo motor 20. A threaded sleeve A18 and a threaded sleeve B19 are threadedly connected to the outside of the bidirectional threaded rod 17, with threaded sleeve A18 located to the left of threaded sleeve B19. A drive plate A16 is snapped onto the outside of threaded sleeve A18, and a cooling rack A3 for cooling the upper mold 6 and the lower mold 7 is welded to the outside of drive plate A16. A drive plate B21 is snapped onto the outside of threaded sleeve B19, and the drive plate... A cooling rack B14 for cooling the upper mold 6 and the lower mold 7 is welded to one side of B21. A heat-conducting layer 5 for heat transfer on the upper mold 6 and the lower mold 7 is bonded to the inner side of the cooling rack A3 and the cooling rack B14. A gear A24 is sleeved on the outer side of the bidirectional threaded rod 17, and a synchronous belt 25 is meshed with the outer side of the gear A24. A gear B31 is meshed with the inner side of the synchronous belt 25 away from the gear A24, and a bidirectional lead screw 28 is snapped into the inner side of the gear B31. A threaded sleeve A29 and a threaded sleeve B32 are threaded to the outer side of the bidirectional lead screw 28, and the threaded sleeve A29 is located to the left of the threaded sleeve B32. A protective plate A8 is welded to the outer side of the threaded sleeve A29, and a protective plate B23 is welded to the outer side of the threaded sleeve B32.

[0030] During use, after the upper mold 6 and lower mold 7 have cooled down, the servo motor 20 inside the fixed frame 15 is driven by the external controller to rotate the bidirectional threaded rod 17. The threaded sleeves A18 and B19 outside the bidirectional threaded rod 17 are both limited by the external structure and move laterally in opposite directions outside the bidirectional threaded rod 17. Then, the threaded sleeve A18 drives the drive plate A16 to move, and the threaded sleeve B19 drives the drive plate B21. Subsequently, the drive plate A16 drives the cooling rack A3 to separate from the upper mold 6 and lower mold 7, and the drive plate B21 drives the cooling rack B14 to separate from the upper mold 6 and lower mold 7. This makes it easy to remove the workpiece formed in the upper mold 6 and lower mold 7, and also makes it easy to inspect the upper mold 6 and lower mold 7.

[0031] When protective frames A and B are removed from the upper mold 6 and lower mold 7, the gear A24, which is screwed on the outside of the bidirectional threaded rod 17, drives the synchronous belt 25 to rotate. Then, the synchronous belt 25 drives the bidirectional lead screw 28, which is screwed on the inside of the gear B31, to rotate. Then, the thread sleeves A29 and B32 outside the bidirectional lead screw 28 are limited by the external structure and move laterally towards each other outside the bidirectional lead screw 28. Then, the thread sleeve A29 drives the protective plate A8 to move, and the thread sleeve B32 drives the protective plate B23 to move, so that the protective plates A8 and B23 move to the outside of the heat-conducting plate 10 outside the water tank 22, thereby facilitating the protection of the heat-conducting plate 10.

[0032] For cooling treatment of the upper mold 6 and the lower mold 7, for example, such as Figure 1 As shown, this utility model also includes a base frame 9 welded to the bottom of the fixing frame 15, and a water tank 22 for holding cooling water is fixed to the inner side of the base frame 9 with screws. A heat-conducting plate 10 for heat dissipation inside the water tank 22 is fixed to the outside of the water tank 22 with screws. A branch pipe 30 is inserted into the bottom of the water tank 22, and a pump body 12 is fixed to the end of the branch pipe 30 away from the water tank 22 with screws. A connecting pipe 11 is fixed to one side of the pump body 12 with screws. A conveying box 1 is fixed to the end of the connecting pipe 11 away from the pump body 12 with screws. A fixing pipe A2 and a fixing pipe B13 are symmetrically inserted into the outside of the conveying box 1, and the fixing pipe A2 is located to the left of the fixing pipe B13.

[0033] When cooling the upper mold 6 and the lower mold 7 is required, the pump body 12 outside the fixed frame 15 is controlled by an external controller to transport water from the water tank 22 to the pump body 12 through the branch pipe 30. Then, the connecting pipe 11 on one side of the pump body 12 transports the water to the conveying box 1. Subsequently, the fixed pipe A2 outside the conveying box 1 transports the water to the cooling rack A3, and the fixed pipe B13 outside the conveying box 1 transports the water to the cooling rack B14. The cooling cavities in the cooling rack A3 and the cooling rack B14 are curved, which extends the contact time between the cooling water and the upper mold 6 and the lower mold 7, thereby facilitating the cooling process of the upper mold 6 and the lower mold 7.

[0034] To improve water resource utilization efficiency, for example, such as Figure 1 As shown, the present invention also includes a fixed pipe A2 with one end away from the conveying box 1 connected to the top of the cooling rack A3 by screws, a fixed pipe B13 with one end away from the conveying box 1 connected to the top of the cooling rack B14 by screws, and a return pipe 33 for water to flow back to the water tank 22 is inserted into the bottom of both the cooling rack A3 and the cooling rack B14.

[0035] When in use, after the cooling racks A3 and B14 cool the upper mold 6 and the lower mold 7, the water in the cooling racks A3 and B14 flows into the water tank 22 through the return pipe 33 inserted at the bottom, thereby improving the utilization rate of water resources.

[0036] To allow material to enter the upper mold 6 and the lower mold 7, for example, such as Figure 1 As shown, the present invention also includes an injection port 4 at the top of the upper mold 6, which allows material to enter the upper mold 6 and the lower mold 7.

[0037] During use, the injection port 4 at the top of the upper mold 6 allows the material to enter the upper mold 6 and the lower mold 7.

[0038] To improve the stability of the movement of protective plates A8 and B23, for example, such as Figure 1 As shown, the present invention also includes sleeves 27 welded to the outside of both the protective plate A8 and the protective plate B23, and a support rod 26 slidably connected to the inside of the sleeves 27.

[0039] When the protective plates A8 and B23 move during use, the sleeves 27 welded to the outside of the protective plates A8 and B23 slide outside the support rods 26 that are screwed into the base frame 9, thereby improving the stability of the movement of the protective plates A8 and B23.

[0040] For electrical equipment to function properly, for example, such as Figure 1 , Figure 2 As shown, the present invention also includes that the input terminals of the pump body 12 and the servo motor 20 are both electrically connected to the power supply terminal of an external power source.

[0041] When in use, the electrical equipment works normally by connecting to an external power source.

[0042] In use, the material is fed into the upper mold 6 and the lower mold 7 through the injection port 4 at the top of the upper mold 6. Then, the pump body 12 outside the fixing frame 15, controlled by an external controller, pumps water from the water tank 22 into the pump body 12 via the branch pipe 30. The connecting pipe 11 on one side of the pump body 12 then pumps the water into the conveying box 1. Subsequently, the fixing pipe A2 outside the conveying box 1 pumps the water into the cooling rack A3, and the fixing pipe B13 outside the conveying box 1 pumps the water into the cooling rack B14. The cooling cavities in both the cooling rack A3 and the cooling rack B14 are curved, extending the contact time between the cooling water and the upper mold 6 and the lower mold 7. Meanwhile, the heat-conducting layer 5 inside cooling racks A3 and B14 transfers heat from the upper mold 6 and lower mold 7. Water from cooling racks A3 and B14 then flows into water tank 22 through the bottom-connected return pipe 33. Subsequently, the heat-conducting plate 10 outside water tank 22 cools the water entering the tank, thereby improving water resource utilization and facilitating the cooling of the upper mold 6 and lower mold 7. After the upper mold 6 and lower mold 7 have cooled, the servo motor 20 inside the fixed frame 15, driven by an external controller, rotates the bidirectional threaded rod 17. The threaded sleeve A18 and threaded sleeve outside the bidirectional threaded rod 17... Both B19 and B19 are limited by the external structure and move laterally in opposite directions outside the bidirectional threaded rod 17. Then, the threaded sleeve A18 drives the drive plate A16 to move, and the threaded sleeve B19 drives the drive plate B21. Subsequently, the drive plate A16 drives the cooling rack A3 to separate from the upper mold 6 and the lower mold 7, and the drive plate B21 drives the cooling rack B14 to separate from the upper mold 6 and the lower mold 7. This facilitates the removal of the workpieces formed in the upper mold 6 and the lower mold 7, and also facilitates the maintenance of the upper mold 6 and the lower mold 7. At the same time, the gear A24, which is screwed to the outside of the bidirectional threaded rod 17, drives the synchronous belt 25 to rotate, and then the synchronous belt 25 drives the gear B18 to rotate. The double-acting screw 28, which is secured by screws on the inner side of 31, rotates. Then, the threaded sleeves A29 and B32 outside the double-acting screw 28 are limited by the external structure and move laterally towards each other outside the double-acting screw 28. Then, the threaded sleeve A29 drives the protective plate A8 to move, and the threaded sleeve B32 drives the protective plate B23 to move. The support sleeves 27 welded to the outside of the protective plates A8 and B23 slide outside the support rods 26 fixed by screws inside the base frame 9, which improves the stability of the movement of the protective plates A8 and B23. Subsequently, the protective plates A8 and B23 move to the outside of the heat-conducting plate 10 outside the water tank 22, thereby facilitating the protection of the heat-conducting plate 10.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
