Description

Technical Field

[0001] This utility model relates to the field of refrigerator parts production technology, specifically a deburring device for the production of refrigerator injection molded parts. Background Technology

[0002] Refrigerator injection molded parts are plastic components manufactured through injection molding. They are mainly used in refrigerator doors, drawers, grilles, and inner door panels. They are characterized by complex structures, high precision requirements, and low-temperature resistance. During refrigerator assembly, different plastic components are usually injection molded to facilitate subsequent assembly work. However, during the injection molding process, due to factors such as the mold parting surface, gate, and cooling system, the plastic may not be able to completely fill the mold during injection, or the mold closing pressure may be uneven, resulting in burrs on the surface of the molded parts.

[0003] Burrs not only affect the appearance of injection molded parts, making the product look rough or unrefined and leaving a bad impression on consumers, but also require deburring equipment. However, existing deburring equipment has significant limitations when dealing with burrs on the surface of sheet-like injection molded parts for refrigerators. On the one hand, these devices usually use an upper and lower clamping method, which makes it difficult to effectively grind the fixed parts when fixing the sheet-like injection molded parts, requiring secondary processing and seriously affecting processing efficiency. In addition, there is a lack of effective measures to deal with the large amount of dust generated during the deburring process, which not only deteriorates the working environment but also increases the difficulty of cleaning, further restricting the improvement of production efficiency.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4As shown, a deburring device for producing refrigerator injection molded parts includes a support shell 1 and a support frame 2 fixed to both sides of the support shell 1. A conveying component 3 is provided inside the support shell 1. The conveying component 3 includes a first motor 301. A hydraulic rod 4 is fixedly connected to the top of the inner cavity of the support frame 2. A movable plate 5 is fixedly connected to the bottom of the hydraulic rod 4. A connecting plate 6 is fixedly connected to one side of the bottom of the movable plate 5. The height of the movable plate 5 can be adjusted by the support frame 2 in conjunction with the hydraulic rod 4, thereby facilitating the adjustment of the deburring force. The conveying component 3 facilitates the conveying, grinding and unloading of the plate-shaped injection molded parts that need to be deburred, thereby improving the deburring efficiency.

[0023] The connecting shell 7 is located at the bottom of the movable plate 5. The interior of the connecting shell 7 contains a grinding component 8, which includes a third motor 801. An adjusting component 9 for adjusting the connecting shell 7 is fixedly connected to one side of the connecting plate 6. The adjusting component 9 includes a second motor 901 and a fixing rod 902. Support plates 20 are fixedly connected to both sides of the inner cavity of the support shell 1. By using the connecting shell 7 at the bottom of the movable plate 5 and cooperating with the adjusting component 9, the grinding component 8 installed inside the connecting shell 7 can be driven to descend synchronously when the movable plate 5 descends, thereby performing deburring work on the plate-shaped injection molded part. The support plates 20 located on both sides inside the support shell 1 can improve the strength of the bottom support when the plate-shaped injection molded part is adsorbed, so that the plate-shaped injection molded part will not put pressure on the conveyor belt 304.

[0024] Both sides of the top of the movable plate 5 are fixedly connected with sliding rods 10. The top of the sliding rods 10 extends through to the outside of the support frame 2. The sliding rods 10 are fixed to the top of the movable plate 5 and extend to the outside of the support frame 2. When the movable plate 5 moves, the sliding rods 10 will slide in coordination with the inside of the support frame 2, which can improve the stability of the movable plate 5 when it moves up and down.

[0025] The first motor 301 is fixed to one side of the support shell 1. The output end of the first motor 301 extends into the interior of the support shell 1 and is fixedly connected to the first transmission rod 302. One end of the first transmission rod 302 is rotatably connected to the inner wall of the support shell 1 through a bearing. Both sides of the surface of the first transmission rod 302 are fixedly connected to the first meshing wheel 303. The surface of the first meshing wheel 303 is meshed with the conveyor belt 304. The other side of the interior of the conveyor belt 304 is meshed with the second meshing wheel 305. The interior of the second meshing wheel 305 is fixedly connected to the second transmission rod 306. Both ends of the second transmission rod 306 are rotatably connected to the inner wall of the support shell 1 through bearings. By turning on the first motor 301, the first transmission rod 302 can drive the first meshing wheel 303 to mesh with the conveyor belt 304. While the conveyor belt 304 is conveying, it will also mesh with the second meshing wheel 305 and cooperate with the support of the second transmission rod 306 to assist the conveyor belt 304 in conveying work, so that the plate-shaped injection molded parts that need to be deburred can be continuously conveyed and processed.

[0026] A cylinder 11 is fixedly connected to the bottom of the inner cavity of the support shell 1, and an extension frame 12 is fixedly connected to the top of the cylinder 11. A vacuum pump 13 is fixedly connected to the bottom of the inner cavity of the support shell 1. One end of the vacuum pump 13 passes through a pipe to the top of the extension frame 12 and is fixedly connected to a suction cup 14. A limiting rod 15, which is fixedly connected to the inner wall of the support shell 1, is slidably connected inside the extension frame 12. A fan 16 is fixedly connected to one side of the support shell 1, and one end of the fan 16 is connected to a retractable pipe 17. Both sides of the connecting shell 7 are fixed. A silicone flexible board 18 is connected, and multiple exhaust pipes 19 are connected to the top of the silicone flexible board 18. The ports of the exhaust pipes 19 are integrated and connected in parallel with the retractable pipe 17. The air pump 13 is existing technology, which extracts gas from the sealed space through mechanical action, thereby creating a low-pressure or vacuum environment. It should be noted that a negative pressure space for collecting dust is set at the exhaust fan 16. When the impeller of the exhaust fan 16 rotates, air is drawn in from the air inlet of the fan. The air is accelerated by the impeller, and the air velocity is increased by the action of the blades. The high-speed gas is discharged through the exhaust port, thereby achieving the purpose of air flow. All of the above are existing technologies, which can be clearly understood by those skilled in the art, and will not be elaborated here. Then, during use, if the user needs to adsorb the plate-shaped injection molded part onto the top of the conveyor 3 for subsequent deburring work, the cylinder 11 can be opened to limit the extension frame 12 to rise on the surface of the limit rod 15, and drive the suction cup 14 to adhere to the bottom of the plate-shaped injection molded part. Then, the air pump 13 is turned on to form a negative pressure between the suction cup 14 and the plate-shaped injection molded part with the pipeline, thereby positioning the plate-shaped injection molded part and preventing it from shaking during deburring. At the same time, it avoids the problem of grinding dead corners caused by traditional fixing methods. During the grinding work, if the user needs to adsorb the grinding dust, the exhaust fan 16 can be turned on to guide the dust generated during deburring through the exhaust pipe 19 inside the silicone soft plate 18 on both sides of the connecting shell 7 to the inside of the telescopic pipe 17. Finally, the dust is adsorbed into the negative pressure space set at the exhaust fan 16, thereby improving the hygiene of the working environment and reducing the spread of dust.

[0027] The second motor 901 is fixed to one side of the connecting plate 6, and the retaining rod 902 is fixed between the connecting plate 6 and the support frame 2. The output end of the second motor 901 passes through to one side of the connecting plate 6 and is fixedly connected to a threaded rod 903. One end of the threaded rod 903 is rotatably connected to the support frame 2 through a bearing. The surface of the threaded rod 903 is threadedly connected to a threaded sleeve 904 that slides and cooperates with the retaining rod 902. The bottom of the threaded sleeve 904 is fixedly connected to the connecting shell 7. By turning on the second motor 901, the threaded rod 903 can be rotated. When the threaded rod 903 rotates, the threaded sleeve 904 will move on the surface of the retaining rod 902, synchronously driving the connecting shell 7 to adjust left and right, thereby facilitating the adjustment of the grinding parts 8 inside the connecting shell 7.

[0028] The third motor 801 is fixed to one side of the connecting shell 7. The output end of the third motor 801 extends into the interior of the connecting shell 7 and is fixedly connected to the third meshing roller 802. The surface of the third meshing roller 802 is meshed with a polishing belt 803. One end of the third meshing roller 802 is rotatably connected to the inner wall of the connecting shell 7 through a bearing. One side of the interior of the polishing belt 803 is meshed with a fourth meshing roller 804. Both ends of the fourth meshing roller 804 are rotatably connected to the inner wall of the connecting shell 7 through bearings. When the user needs to polish the plate-shaped injection molded part, the third motor 801 can be turned on. The output end of the third motor 801 drives the third meshing roller 802 to mesh with the polishing belt 803, and also drives the fourth meshing roller 804 to rotate, thereby improving the stability of the polishing belt 803 transmission. With the transmission of the polishing belt 803, the burrs on the surface of the plate-shaped injection molded part can be polished.

[0029] Working principle: First, the sheet-shaped injection molded part to be deburred is placed on the conveyor belt 304. Turning on the first motor 301 causes the first transmission rod 302 to drive the first meshing wheel 303 to engage the conveyor belt 304. Simultaneously, the conveyor belt 304 engages the second meshing wheel 305, which, in conjunction with the support of the second transmission rod 306, assists the conveyor belt 304 in its conveying operation. The sheet-shaped injection molded part is then conveyed to the top of the suction cup 14. At this point, the cylinder 11 is opened, causing the extension frame 12 to rise and be limited on the surface of the limiting rod 15, thus causing the suction cup 14 to adhere to the bottom of the sheet-shaped injection molded part. Then… The vacuum pump 13, in conjunction with the pipeline, creates negative pressure between the suction cup 14 and the plate-shaped injection molded part, thereby positioning the plate-shaped injection molded part. The support plates 20 located on both sides inside the support shell 1 enhance the strength of the side supports during the suction of the plate-shaped injection molded part, preventing the plate-shaped injection molded part from putting pressure on the conveyor belt 304. The first motor 301 is then turned off, and the third motor 801 can be turned on. The output end of the third motor 801 drives the third meshing roller 802 to engage the grinding belt 803, and also drives the fourth meshing roller 804 to rotate, thereby improving the stability of the grinding belt 803 transmission. As the grinding belt 803 is driven, the burrs on the surface of the plate-shaped injection molded part can be ground. Before this, the hydraulic rod 4 is opened, causing the movable plate 5 to drive the connecting plate 6 and the adjusting part 9 to descend, thereby allowing the connecting shell 7 to descend and the grinding belt 803 to fit against the surface of the plate-shaped injection molded part for grinding. If the user needs to remove the dust generated during grinding, the exhaust fan 16 can be turned on to guide the dust generated during deburring through the exhaust pipes 19 inside the silicone flexible plates 18 on both sides of the connecting shell 7 to the interior of the retractable pipe 17, and finally the dust is absorbed by the exhaust fan 16. Within the negative pressure space, the working environment is improved and dust spread is reduced. When the user needs to adjust the grinding position left or right, the second motor 901 can be turned on to rotate the threaded rod 903. When the threaded rod 903 rotates, the threaded sleeve 904 will be on the surface of the fixed rod 902, which will simultaneously drive the connecting shell 7 to adjust left or right, thereby facilitating the adjustment of the grinding part 8 inside the connecting shell 7. After grinding is completed, the vacuum pump 13 is turned off and the cylinder 11 is reset. Then, the first motor 301 is driven again, which, together with the conveyor belt 304, transports the deburred plate-shaped injection molded part out.
