Description

Technical Field

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

[0002] During the injection molding process, material overflow from the mold parting surface, ejector pin holes, or gates often results in burrs (also known as rough edges or flash) after molding. These burrs not only affect the appearance and dimensional accuracy of the parts but may also interfere with subsequent assembly or functionality. Traditional deburring methods include manual trimming, mechanical grinding, or processing with specialized equipment. Among these, automated deburring devices are gradually becoming an industry trend due to their efficiency and consistency advantages.

[0003] Currently, commonly used deburring devices for injection molded parts typically employ manual hand-held grinding tools or single-direction automated equipment. For injection molded parts with complex structures, multiple flipping of the workpiece is often required to complete double-sided deburring. This method has several drawbacks: manual operation is inefficient and inconsistent, easily causing surface damage due to uneven operating force; traditional automated equipment can only process a single surface, and the processing flow must be interrupted when flipping the workpiece, severely impacting production efficiency. Therefore, a deburring device for injection molded parts processing is proposed. Utility Model Content

[0026] Example

[0027] In current technology, commonly used deburring devices for injection molded parts generally employ manual hand-held grinding tools or single-direction automated equipment. For injection molded parts with complex structures, multiple flipping of the workpiece is often required to complete the double-sided deburring operation. This method has the following drawbacks: manual operation is inefficient and inconsistent, and uneven operating force can easily damage the surface of the part; traditional automated equipment can only process a single surface, and the processing flow must be interrupted when flipping the workpiece, which seriously affects production efficiency.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a deburring device for processing injection molded parts, including a base 1, a first fixing frame 2, and a second fixing frame 3. The first fixing frame 2 and the second fixing frame 3 are both fixedly connected to the top of the base 1. The base 1 supports and fixes the fixing frames. The first fixing frame 2 and the second fixing frame 3 are respectively provided with a front deburring component 4 and a back deburring component 5. The front deburring component 4 and the back deburring component 5 use the same specification conveying component 6 as a base platform. Two sets of water collection tanks 7 are opened on the upper surface of the base 1. The two sets of water collection tanks 7 are located inside the first fixing frame 2. The grinding debris on the front deburring component 4 flows into the water collection tanks 7 with the water to prevent sewage from overflowing.

[0029] The conveying assembly 6 includes a geared motor 61, a drive wheel 62, and a driven wheel 63. The output end of the geared motor 61 is fixedly connected to the drive wheel 62 via a rotating shaft. A flat belt 65 is sleeved on the outer side of the drive wheel 62 and the driven wheel 63. The injection molded part to be trimmed is placed on the surface of the flat belt 65 and conveyed for trimming. Multiple transmission rollers 64 are provided between the drive wheel 62 and the driven wheel 63. The two ends of the transmission rollers 64 are rotatably connected to the fixed frame via bearings. The surface of the transmission rollers 64 is in contact with the non-drive side of the flat belt 65 to enhance the stability of the belt support. The transmission rollers 64 increase the stability of the flat belt 65 during the conveying of the injection molded part.

[0030] The front deburring assembly 4 includes a first support frame 41, which is fixedly connected to a first fixed frame 2. A first motor 42 is mounted on the top of the first support frame 41, and a first grinding wheel 43 is fixedly connected to the output end of the first motor 42. A horizontal pipe 44 and an air knife 46 are fixedly mounted on one side inside the first fixed frame 2. Several nozzles 45 are connected to the bottom of the horizontal pipe 44, and a water pipe is connected to the top of the horizontal pipe 44. The water pipe is connected to an external pipe, and high-pressure water flows through the nozzles 45 to inject deburring material onto the upper surface. The plastic parts are sprayed and cleaned to prevent oil stains from adhering to the surface of the injection molded parts, which could cause the suction cup 51 to slip or fall off. The first grinding wheel 43, the horizontal tube 44 and the air knife 46 are all located above the conveying assembly 6. The air speed at the outlet of the air knife 46 is set to 15-20m / s to ensure that the water is dried and to generate a horizontal thrust of 0.5-1N. The air outlet angle of the air knife 46 is 40-50 degrees downward. While drying the upper surface of the injection molded parts, the air knife 46 blows the injection molded parts toward the direction of the guide plate 8.

[0031] The reverse deburring assembly 5 includes several suction cups 51 and a second support frame 52. The suction cups 51 are divided into three groups, and the three groups of suction cups 51 are evenly distributed on the surface of the flat belt 65 of the reverse deburring assembly 5. The surface of the flat belt 65 of the reverse deburring assembly 5 station is equidistantly distributed with multiple groups of vacuum suction cups 51 at 300mm intervals. The suction cups 51 are made of high-temperature resistant silicone material to achieve dynamic adsorption and positioning of injection molded parts. The center distance tolerance of the suction cup 51 array is controlled within ±0.2mm to ensure repeatability and positioning accuracy during workpiece flipping. The three groups of suction cups 51 are distributed in an isosceles triangle, with one group located in the workpiece's center of gravity projection area and the other two groups symmetrically distributed at both ends of the workpiece's long axis. The suction cups 51 are made of high-elasticity silicone material (Shore hardness 40A±5) to adapt to different curved workpieces. The top of the inner cavity of the suction cup (51) is provided with an annular rib with a height of 0.3-0.5mm, which is used to form a secondary sealing cavity to enhance the negative pressure during adsorption. To maintain pressure and prevent insufficient suction force during high-speed movement, a second motor 53 is fixedly installed at the bottom of the second support frame 52. The output end of the second motor 53 is fixedly connected to the second grinding wheel 54. A guide plate 8 is provided between the first fixed frame 2 and the second fixed frame 3. A support rod 9 is fixedly connected between the guide plate 8 and the base 1. The injection molded part with the surface deburred moves to the guide plate 8 along the flat belt 65 of the front deburring component 4 station. It is blown by the air knife 46 and moves along the guide plate 8 to the flat belt 65 of the back deburring component 5 station, where it is attracted by the suction cup 51. The axial distance between the first grinding wheel 43 and the second grinding wheel 54 is greater than the maximum thickness of the workpiece by 10mm to avoid mechanical interference during bidirectional grinding. The end of the guide plate 8 is tilted downward at 15°, and the vertical distance between its lower edge and the highest point of the suction cup 51 is 1.2 times the thickness of the workpiece, ensuring that the workpiece is first pressed and then attracted when it contacts the suction cup.

[0032] The working principle or structural principle is as follows: The injection molded part to be deburred is placed on the surface of the flat belt 65 of the front deburring assembly 4. The reduction motor 61 drives the flat belt 65 to move through the drive wheel 62, thereby moving the injection molded part to below the first grinding wheel 43. The first motor 42 drives the first grinding wheel 43 to rotate at high speed, removing the burrs from the injection gate on the upper surface of the injection molded part. The injection molded part moves to the horizontal pipe 44, which is connected to an external water pipe. High-pressure cleaning fluid is sprayed onto the surface of the injection molded part through the nozzle 45 to prevent oil stains on the surface of the injection molded part. After cleaning, the injection molded part is deburred along with the front deburring assembly. The flat belt 65 of component station 4 moves to the guide plate 8, where it is blown by the air knife 46 and its own inertia, drying the surface moisture of the injection molded part. The injection molded part moves along the guide plate 8 to below the flat belt 65 of the reverse deburring component station 5, where it is attracted by the suction cup 51. The guide plate 8 and the suction cup 51 squeeze the injection molded part, increasing the suction force between the suction cup 51 and the injection molded part. The injection molded part is held by the suction cup 51 and moves with the flat belt 65 of the reverse deburring component station 5. The second motor 53 drives the second grinding wheel 54 to rotate at high speed, deburring the reverse side of the injection molded part, realizing automatic bidirectional deburring of the injection molded part.

[0033] In summary, the injection molded part to be deburred is placed on the surface of the flat belt 65 of the front deburring assembly 4 and moved. The first motor 42 drives the first grinding wheel 43 to rotate at high speed to deburr the upper surface of the injection molded part. High-pressure cleaning fluid is sprayed onto the surface of the injection molded part through the nozzle 45. After cleaning, the injection molded part is blown by the air knife 46 and, due to its own inertia, moves along the guide plate 8 to below the flat belt 65 of the reverse deburring assembly 5, where it is attracted by the suction cup 51 and moves with the flat belt 65 of the reverse deburring assembly 5. The second motor 53 drives the second grinding wheel 54 to rotate at high speed to deburr the reverse side of the injection molded part, realizing automatic bidirectional deburring of the injection molded part. The suction cup 51 is cleaned regularly to prevent impurities from affecting the suction power of the suction cup 51. The first motor 42 and the second motor 53 are model 57GY manufactured by Guangzhou Zhongtian Motor Co., Ltd., and the geared motor 61 is model CLJSJ-CH02 manufactured by Kunshan Taiya Electromechanical Technology Co., Ltd. Since the structure and operating principle of this model are existing technologies, their structure and operating principle will not be described in detail here.
