Description

Technical Field

[0001] This application relates to the technical field of metal castings, and particularly to a cooling device for metal castings. Background Art

[0002] Metal castings are metal formed objects obtained through various casting methods. These objects are made of molten metal that has been smelted, and are injected into pre-prepared molds through pouring, injection, suction, or other casting methods, and are obtained after subsequent processing means such as grinding after cooling. They have a certain shape, size, and performance. After the metal casting is completed, its temperature is usually much higher than room temperature. The purpose of cooling is to gradually reduce the temperature of the casting to balance with the surrounding environmental temperature, to ensure the stability of the internal structure of the casting, to avoid defects such as deformation and cracks, and at the same time to improve the mechanical properties and surface quality of the casting.

[0003] For some small metal castings, after they are completed, they are uniformly placed in a cooling box for cooling. When cooling, it is necessary to wait for the metal castings in the cooling box to cool down, then take them out, and then put in other metal castings. That is to say, during the process of replacing the metal castings in the cooling box, no metal castings are being cooled. This results in the cooling of metal castings not being able to be carried out continuously. This cooling method has low efficiency, affects the cooling speed, and it is inconvenient to take out the metal castings in the cooling box, which affects the production efficiency. Therefore, to solve the above problems, this application provides a cooling device for metal castings. Utility Model Content

[0013] By starting the motor, the second vertical rod rotates, driving the third vertical rod to rotate, and the first vertical rod is rotated by the setting of the transmission belt. When the first vertical rod rotates one circle, the rotating rod rotates ninety degrees, so that the supporting assembly intermittently enters the cooling box for cooling. The metal castings in the supporting assembly will be rotated out of the cooling box after cooling. The limit plate is pulled up to separate it from the lower limit cylinder, and the filter plate is pulled out.

The end of each connecting rod 10 away from the rotating rod 7 is fixedly connected with a supporting component 8. The base 1 is provided with and rotatably connected with a first vertical rod 2. The first vertical rod 2 is coaxially and fixedly connected with a rotating disc 3. A round pin 4 is fixedly connected to the upper wall of the rotating disc 3. The round pin 4 intermittently slides through the slot 6 and is slidably connected with the sprocket 5.

[0024] The supporting component 8 includes a supporting box 801 fixedly connected with the connecting rod 10. A sliding groove 806 is provided on the lower wall of the supporting box 801. The longitudinal section of the sliding groove 806 is "T" shaped. A filter screen plate 802 is provided below the supporting box 801. Sliding blocks 807 are fixedly connected to both sides of the upper wall of the filter screen plate 802. The longitudinal section of the sliding block 807 is "T" shaped. The sliding block 807 is slidably connected with the supporting box 801 through the sliding groove 806. An upper limiting cylinder 804 is connected to the side wall of the supporting box 801. A lower limiting cylinder 805 is connected to the side wall of the filter screen plate 802. A limiting plate 803 is slidably arranged in the upper limiting cylinder 804. The limiting plate 803 is slidably connected with the filter screen plate 802 through the lower limiting cylinder 805. A limiting piece is fixedly arranged above the limiting plate 803 to ensure that it will not slide out of the upper limiting cylinder 804.

[0025] A second vertical rod 19 is provided through the base 1 and is rotatably connected thereto. A main gear 11 is coaxially fixedly connected to the lower end of the second vertical rod 19. A motor 9 is fixedly provided on the upper wall of the base 1 to drive the rotation of the second vertical rod 19. A third vertical rod 20 is rotatably provided on the lower wall of the base 1. A secondary gear 12 is coaxially fixedly connected to the third vertical rod 20. The main gear 11 meshes with the secondary gear 12. The third vertical rod 20 is driven by the first vertical rod 2 via a transmission belt 13. The main gear 11 and the secondary gear 12 are arranged to adjust the rotation speed of the first vertical rod 2 so that the intermittent time during the ninety-degree rotation of the rotating rod 7 meets the required time (cooling of the metal casting, removal and placement of the metal casting).

[0026] A cooling box 14 is fixedly provided on the upper wall of the base 1, and a through groove 15 is provided through the side wall of the cooling box 14. The through groove 15 is provided in conjunction with the supporting assembly 8, and the supporting assembly 8 enters the interior of the cooling box 14 through the through groove 15. A main cooling pipe 16 and several secondary cooling pipes 17 are fixedly provided inside the cooling box 14. The main cooling pipe 16 is connected to the external water source. The main cooling pipe 16 and the secondary cooling pipe 17 are both connected. The lower wall of the secondary cooling pipe 17 is fixedly connected and connected to several nozzles 18. The nozzle 18 is a common water spray head component on the market and will not be described in detail here. When the device is in the initial position, a supporting assembly 8 is located directly below the nozzle 18. It is conceivable to provide a drainage trough below the cooling box 14 so that the cooling water used for cooling can be discharged through the drainage trough.

[0027] During actual use, a metal casting to be cooled is placed inside the support assembly 8, the motor 9 is started, the second vertical rod 19 rotates, and due to the meshing of the main gear 11 and the secondary gear 12, the third vertical rod 20 is driven to rotate. The first vertical rod 2 is rotated by the setting of the transmission belt 13. When the first vertical rod 2 rotates one circle, the round pin 4 slides into a notch 6 and separates from it. This process drives the groove wheel 5 to rotate 90 degrees, thereby rotating the rotating rod 7 90 degrees. The support assembly 8 intermittently enters the cooling box 14 for cooling;

[0028] After cooling, the metal casting in the supporting assembly 8 will be rotated out of the cooling box 14, and the limit plate 803 will be pulled up to separate it from the lower limit cylinder 805, and the filter plate 802 will be pulled out. Due to the obstruction of the supporting box 801, the metal casting will fall into the collection bag below during the process of pulling out the filter plate 802, and then the metal casting to be cooled will be placed inside the supporting box 801. When the casting in one supporting box 801 is taken out and the casting to be cooled is placed in, the metal casting in the other supporting box 801 can be cooled. The removal of the metal casting is also more convenient and quick, thereby improving work efficiency.
