Technical Field

[0001] The utility model relates to the technical field of aluminum shell die-casting, and in particular to a lamp aluminum shell die-casting spray device. Background Art

[0002] As a common lighting device, the shell of the integrated downlight is usually made of aluminum alloy through die-casting. During the die-casting process, the high-temperature aluminum alloy liquid is injected into the mold and quickly solidifies under high pressure. In order to ensure product quality and improve production efficiency, the die-casting needs to be cooled immediately after forming.

[0003] Traditional cooling methods include natural cooling, air cooling and water cooling. However, these cooling methods will cause great internal stress inside the die-casting parts, and may even cause cracking, if the die-casting aluminum or die-casting zinc is directly cooled by immersion or water spraying. The natural air cooling method requires a long cooling time, which not only takes up a lot of heat dissipation space, but also has low cooling efficiency, thus extending the entire production cycle.

[0004] Therefore, in view of the above problems, a spray device for die-casting aluminum shell of lamp is proposed, which sprays and cools the aluminum shell of lamp immediately after it is clamped out of the furnace, so as to achieve uniform cooling and rapid temperature reduction.

Limit rings are provided on both sides of the upper part of the guide frame. The pull rope passes through the limit ring on the same side, and the end of the pull rope is connected to the sliding block on the same side.

[0008] Furthermore, it also includes a support plate and a cleaning brush. The support plates are symmetrically arranged on the upper side of the guide frame, and a cleaning brush attached to the sprayer is inserted between the two support plates.

[0009] Furthermore, it also includes nuts, and both sides of the cleaning brush are threadedly provided with nuts for fixing the position.

[0010] Furthermore, the spray of the sprayer operates in a circumferential annular trajectory, thereby forming a fan-shaped surrounding spray.

[0011] Furthermore, the connecting pipe is a flexible hose, which can be deformed accordingly as the sprayer moves to adapt to the movement trajectory of the sprayer.

[0020] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0021] Embodiment: A lamp aluminum housing die-casting spray device, such as Figure 1-Figure 5 As shown, it includes a fixed column 1, a booster pump 2, a hopper 3, a fixed frame 4, a guide frame 5, a connecting pipe 6, a sprayer 7, a driving assembly, a sliding block 12 and an elastic member 13. A booster pump 2 is installed on the top of the fixed column 1, and a hopper 3 is arranged on the top of the booster pump 2 through a pipeline. The hopper 3 can be loaded with a cooling medium and supply the cooling medium to the booster pump 2. The booster pump 2 pressurizes the cooling medium and ensures the purity of the medium. After the hopper 3 is fed, the hopper 3 should be closed in time to prevent the entry of impurities; a fixed frame 4 is arranged on the left side of the booster pump 2, and a semi-annular guide frame 5 is arranged on the fixed frame 4. A sprayer 7 with a matching shape is arranged in the guide frame 5. The spray of the sprayer 7 operates in a circumferential annular trajectory, thereby forming a fan-shaped surrounding spray effect, making the spray more The spray is evenly distributed, and the spreading area is further improved to ensure the cooling effect of the spray on the workpiece, and the front and rear sides of the sprayer 7 are provided with sliding blocks 12 that slide with the inner side of the guide frame 5, and the two sliding blocks 12 are provided with elastic members 13 between the guide frame 5. In this embodiment, the elastic member 13 is a spring, which is used to promote the operation of the sprayer 7. The outlet of the booster pump 2 is connected with a connecting pipe 6, and the other end of the connecting pipe 6 is connected with the sprayer 7. The connecting pipe 6 is made of a retractable hose material, which can form corresponding deformation as the sprayer 7 moves to adapt to the movement trajectory of the sprayer 7, thereby achieving mutually coordinated operation and ensuring the smoothness of the overall operation of the device; the top of the fixed frame 4 is provided with a driving component for driving the sliding block 12 to move, so that the operation of the sprayer 7 is more automated.

[0022] like Figure 1 and Figure 3 As shown, the driving assembly includes a dual-axis motor 8, a winding wheel 9, a pull rope 10 and a limit ring 11. The dual-axis motor 8 is fixedly installed on the top of the fixed frame 4. The two output shafts of the dual-axis motor 8 are provided with winding wheels 9. The pull rope 10 is wound on the winding wheels 9. The winding wheels 9 can reel in the pull rope 10 to achieve the reciprocating pulling operation of the pull rope 10. The front and rear sides of the guide frame 5 are provided with limit rings 11. The pull rope 10 passes through the limit ring 11 on the same side, and the end of the pull rope 10 is connected to the sliding block 12 on the same side, thereby realizing the pulling operation of the sprayer 7.

[0023] like Figure 5 As shown, it also includes a support plate 14 and a cleaning brush 15. The support plates 14 are symmetrically arranged on the front and rear sides of the upper part of the guide frame 5. A cleaning brush 15 attached to the sprayer 7 is inserted between the two support plates 14. The cleaning brush 15 can be used to scrape off the scale on the surface of the sprayer 7.

[0024] like Figure 5 As shown, a nut 16 is also included. Both the front and rear ends of the cleaning brush 15 are threadedly provided with nuts 16 for fixing the position. The nut 16 can fix the position between the cleaning brush 15 and the support plate 14, making the overall disassembly and assembly more convenient.

[0025] When the device is needed, first, the staff ensures that the fixed column 1 is placed on a stable table, then adds the cooling medium to the hopper 3, and then starts the pressure pump 2. As the workpiece moves out after the die-casting is formed, the pressure pump 2 extracts the medium and pressurizes the cooling medium, which then flows to the sprayer 7 through the connecting pipe 6, that is, the coolant is sprayed out by the sprayer 7 to perform spray cooling on the workpiece. At the same time, the staff can start the double-axis motor 8 to rotate forward, and the double-axis motor 8 drives the winding wheel 9 to rotate, thereby driving the pull rope 10 to tighten, and then driving the sliding block 12 to slide on the guide frame 5, and the sprayer 7 is also driven to slide. As the sprayer 7 moves, the connecting pipe 6 is pulled to the other end, the elastic member 13 is gradually compressed, and the pull rope 1 0 will be pushed to slide through the limit ring 11, and finally the sprayer 7 will move to the side opposite to the initial position of the sprayer 7, and spray cooling will be performed on the other side of the workpiece, so as to achieve a uniform cooling effect. When the dual-axis motor 8 is controlled to reverse for a period of time, the pull rope 10 is no longer wound by the winding wheel 9, so that the sliding block 12 and the sprayer 7 slide to the initial position along the guide frame 5 under the elastic reset of the elastic member 13. In summary, the pull rope 10 is reciprocated by the dual-axis motor 8 to drive the sprayer 7 to reciprocate, thereby circulating cooling of the workpiece to achieve a more effective cooling effect. At the same time, while the sprayer 7 is operating, the cleaning brush 15 will brush off the scale or dirt on the surface of the sprayer 7. After use, the nut 16 is unscrewed and the cleaning brush 15 is removed for cleaning.
