Description

Technical Field

[0001] The utility model relates to the technical field of injection molding processing, in particular to an injection molding deburring device. Background Art

[0002] Injection molded parts refer to plastic products manufactured using the injection molding process. This manufacturing process is to inject the heated and molten plastic material into the mold through an injection machine. Under certain pressure and temperature conditions, the plastic material cools and solidifies in the mold to eventually form the desired product shape. In the injection molding process, removing burrs is a very important step because burrs will affect the appearance and performance of the product.

[0003] After searching, the utility model with patent number "CN213198487U" provides "a deburring device for injection molded parts, comprising: a frame, a flat plate is fixed on the upper part of the frame, a dust suction chamber is arranged in the frame below the flat plate, and a fan is arranged in the dust suction chamber; cross bars are respectively fixed on both sides above the flat plate, a slide groove is arranged in the rod body at the upper part of the cross bar, a slider is arranged in the slide groove, an arc track is fixed on the upper part of the slider, two ends of the arc track are respectively placed on the slider in the slide groove, a slide rail is opened on one side of the inner arc of the arc track, a base is arranged in the slide rail, a lift is fixed on the base, a motor is connected to the end of the lift, and a polishing machine is arranged on the motor; a through groove is opened in the middle of the cross bar, and the A clamping mechanism is arranged in the through groove; the device can remove burrs of injection molded parts of different shapes in a surrounding manner, solving the problem of low efficiency of traditional manual grinding and deburring. When in use, it can remove burrs of injection molded parts of different shapes in a surrounding manner, solving the problem of low efficiency of traditional manual grinding and deburring. However, due to the limitation of the arc track on the base, it can only slide along the path of the arc track to polish and grind the two side surfaces and the upper surface of the workpiece, but cannot polish the front and back sides of the workpiece. If polishing is required, the workpiece needs to be re-clamped, which will consume time and energy. At the same time, the height of the polishing machine is controlled by a lift. When the surface of the workpiece to be polished is uneven, the height of the lift needs to be adjusted frequently, which is quite inconvenient.

[0025] Furthermore, a plurality of filter holes 31 are provided on the inner bottom surface of the rotating table 3, and the powder produced by polishing and grinding will fall into the dust box 2 through the filter holes 31. A slide groove 32 is provided inside the outer edge of the rotating table 3, and the slide groove 32 provides a sliding path for the pulley 52. ​​A limiting groove 33 is provided on the outer side of the rotating table 3.

[0026] Furthermore, a right-angle plate 51 is welded to the lower end of the column 5, and a pulley 52 is installed inside the right-angle plate 51 through a short axis rotation, and the pulley 52 is slidably installed inside the slide groove 32. When the column 5 is adjusted, the column 5 indirectly drives the pulley 52 to slide inside the slide groove 32. A threaded hole 53 is penetrated through one side of the right-angle plate 51, and a locking bolt 54 is installed on the internal thread of the threaded hole 53, and the locking bolt 54 abuts against the inside of the limiting groove 33. The abutment state of the locking bolt 54 and the limiting groove 33 can fix the position of the column 5 after adjustment. A guide groove 55 is opened inside the column 5, and guide blocks 551 are welded on both sides of the guide groove 55.

[0027] Furthermore, the moving block 6 is slidably installed inside the guide groove 55, and long springs 61 are welded at both ends of the moving block 6, and the other end of the long spring 61 is welded to the inner wall of the guide groove 55. Two groups of long springs 61 clamp the moving block 6 inside the guide groove 55. After adjusting the height of the moving block 6, when the moving block 6 loses external force fixation, the moving block 6 will reset to the middle position inside the column 5, which is the premise for the subsequent movement and polishing. Side grooves 62 are opened on both sides of the moving block 6, and the guide block 551 is slidably installed inside the side grooves 62. When the moving block 6 slides inside the guide groove 55, the side grooves 62 limit the sliding path of the guide block 551, and a fixing buckle 63 is welded at the other end of the moving block 6.

[0028] Furthermore, a connecting block 71 is welded on one side of the C-shaped seat 7, and the connecting block 71 is rotatably installed inside the fixing buckle 63 through a damping shaft 72. The angle between the connecting block 71 and the fixing buckle 63 can be adjusted according to actual conditions to ensure that the polishing side of the polishing wheel 92 is parallel to the side of the workpiece. Fixing ears 73 are welded on both sides of the C-shaped seat 7, and fixing bolts 74 are installed on the internal threads of the fixing ears 73. The fixing bolts 74 can fix the position of the sliding block 8. Through grooves 75 are opened on the upper and lower sides of the C-shaped seat 7, and grooves 76 are opened on both sides of the interior of the C-shaped seat 7. A limit plate 77 is screwed on the other side of the C-shaped seat 7, and the limit plate 77 plays a limiting role in the sliding path of the sliding block 8.

[0029] The cam 82 is welded on both sides of the sliding block 8, and the end of the fixing bolt 74 abuts against one side of the top plate 81. The upper end of the sliding block 8 is welded with a connecting seat 82, and the connecting seat 82 is slidably installed in the through groove 75. The upper end of the connecting seat 82 is welded with a shifting block 83. The staff can adjust the position of the sliding block 8 by manually shifting the shifting block 83. Both ends of the sliding block 8 are welded with protrusions 84, and the protrusion 84 is slidably installed in the groove 76. When the sliding block 8 slides in the C-type seat 7, the groove 76 provides a position limit for the sliding path of the protrusion 84. A fixing seat 85 is welded on one side of the sliding block 8, and the reduction motor 9 is fixedly installed in the fixing seat 85. A short spring 86 is abutted on the other side of the sliding block 8, and the other end of the short spring 86 is welded to the inner wall of the C-type seat 7. Through the elastic deformation of the short spring 86, an elastic top force can be exerted on the sliding block 8, so that it fits tightly with the polishing side of the workpiece.

[0030] Furthermore, a sliding buckle 101 is welded on one side of the beam 10 close to the column 5, and the sliding buckle 101 is slidably installed on the outside of the column 5. An adjusting bolt 102 is installed on the internal thread of the sliding buckle 101, and the end of the adjusting bolt 102 abuts against the outside of the column 5. The height of the beam 10 at the upper end of the workpiece can be adjusted according to the height of the workpiece, and an upper polishing machine 103 is slidably installed inside the beam 10.

[0031] Working principle: First, a deburring device for injection molded parts is moved to the working position. When in use, the first step is to place the workpiece on the upper end of the rotating table 3, and then use the clamping plate 4 to clamp the workpiece. The second step is to adjust the direction of the column 5 according to the polishing side required by the workpiece. First, the locking bolt 54 is unscrewed to make the locking bolt 54 disengage from the limit groove 33. At this time, the direction of the column 5 is manually adjusted to facilitate the polishing of the workpiece. The column 5 drives the pulley 52 to rotate and slide inside the slide groove 32 through the right-angle plate 51. After the adjustment is completed, the locking bolt 54 is tightened and abutted. At this time, the direction of the column 5 is fixed. The third step is to manually polish the workpiece. When the polishing surface of the workpiece is relatively flat, the position of the sliding block 8 can be fixed by the fixing bolt 74 so that the polishing wheel 92 abuts against the side of the workpiece. The fixing bolt 74 is manually rotated, and the fixing bolt 74 abuts against one side of the top plate 81 and pushes the top plate 8 to one side. 1 is moved until the polishing side of the polishing wheel 92 is abutted against the side of the workpiece. In the fourth step, the reduction motor 9 is started. The reduction motor 9 drives the polishing wheel 92 to rotate and polish through the main shaft 91. The height of the C-type seat 7 is manually adjusted. At this time, the moving block 6 slides in the guide groove 55, indirectly driving the polishing wheel 92 to reciprocate on the polishing side of the workpiece. In the fifth step, when the polishing surface of the workpiece is uneven, the fixing bolt 74 can be screwed out. At this time, the sliding block 8 can slide freely inside the C-type seat 7. During polishing and grinding, the staff can change the position of the polishing wheel 92 in real time through the dial block 83 to ensure the polishing effect of the uneven surface. In the sixth step, when the column 5 rotates to the oblique side of the workpiece, an angle appears between the polishing wheel 92 and the workpiece surface. The angle between the connecting block 71 and the fixing buckle 63 can be manually adjusted so that the polishing wheel 92 is always in a parallel state with the workpiece surface. In this way, the use process of a deburring device for injection molded parts is completed.
