Description

Technical Field

[0001] This utility model relates to the field of injection molding part polishing technology, and in particular to equipment for removing burrs from injection molding parts. Background Technology

[0002] In the injection molding industry, the post-production processing of injection molded parts is crucial. During the molding process, burrs often form on the surface of the injection molded parts due to factors such as mold clearance and injection molding technology. These burrs not only affect the appearance quality of the injection molded parts, making their surfaces uneven and rough, reducing the product's aesthetics, but may also hinder subsequent assembly, affecting the fitting accuracy between parts, and even posing safety hazards such as scratches to operators. Therefore, it is necessary to grind and remove burrs from the injection molded parts during processing.

[0003] However, existing deburring equipment still has certain shortcomings in use. During the grinding process, the grinding tools generate a lot of heat due to friction between them and the injection molded parts, which accelerates the wear of the grinding tools and reduces their service life. At the same time, the dust generated will pollute the working environment and endanger the health of the operators. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to provide a burr removal device for injection molded parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The injection molding part deburring equipment includes a support plate slidably connected to a support plate, and a bracket is fixedly connected to the support plate.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example: Reference Figures 1-7 The burr removal equipment for injection molded parts includes a support plate 3 slidably connected to a support plate 1, a bracket 2 fixedly connected to the support plate 1, and further includes: Mounting plate 5 is fixedly connected to bracket 2; Cylinder 14 is fixedly connected to the bottom of mounting plate 5. A connecting plate 9 is fixedly connected to the drive end of cylinder 14, and drive plates 13 are fixedly connected to both sides of the connecting plate 9. The rotating rod 801, which is fixedly connected to the grinding roller 8011, is rotatably connected to the drive plate 13; The drive cylinder 4 is fixedly connected to the mounting plate 5; A drain pipe 401 is fixedly connected to the drive cylinder 4, and the end of the drain pipe 401 away from the drive cylinder 4 is connected to the connecting plate 9. Reference Figure 1 , Figure 2 In practice, an electric telescopic rod can be used to push the bearing plate 3 to slide.

[0018] The connecting plate 9 is a hollow plate, and a nozzle 901 is fixedly connected to the side wall of the connecting plate 9, with the water outlet end of the nozzle 901 facing the grinding roller 8011.

[0019] A sliding plug 402 is slidably connected in the drive cylinder 4, and a water tank 6 is fixedly connected to the mounting plate 5. A water pumping pipe 601 is fixedly connected to the water tank 6, and the end of the water pumping pipe 601 away from the water tank 6 is connected to the drive cylinder 4.

[0020] Reference Figure 4 It should be noted that both the pumping pipe 601 and the drain pipe 401 are equipped with one-way valves.

[0021] A limiting rod 404 is slidably connected to the drive cylinder 4, and the limiting rod 404 is fixedly connected to the slide plug 402.

[0022] A first drive wheel 12 is rotatably connected to the mounting plate 5. A lead screw sleeve 10 is fixedly connected to the first drive wheel 12. A lead screw 403 is connected to the drive cylinder 4. The lead screw 403 is fixedly connected to the slide plug 402, and the lead screw 403 and the lead screw sleeve 10 are threadedly matched.

[0023] A second drive wheel 8012 is fixedly connected to the rotating rod 801, and the first drive wheel 12 is connected to the second drive wheel 8012 through the drive rope 11.

[0024] Reference Figures 1-7 In use, the injection molded part is placed on the support plate 3 and the support plate 3 is slid directly below the grinding roller 8011. The electric push rod 2011 on the bracket 2 is activated, and the electric push rod 2011 drives the pressure plate 2012 to move down, firmly pressing the injection molded part onto the support plate 3. At this time, the cylinder 14 is activated, and the cylinder 14 will push the grinding roller 8011 to move down. After the grinding roller 8011 moves down a certain distance, the grinding roller 8011 will be in contact with the surface of the injection molded part. At this time, the drive motor 8 is activated, and the drive motor 8 drives the rotating rod 801 to rotate, and the grinding roller 8011 on the rotating rod 801 begins to rotate and grind.

[0025] It should be noted that during the grinding process, the support plate 3 can slide left and right, thereby ensuring that the injection molded part can be fully ground by the grinding roller 8011.

[0026] Reference Figures 4-7 When the grinding roller 8011 rotates, the second drive wheel 8012 on the rotating rod 801 rotates accordingly. Since the drive rope 11 connects the first drive wheel 12 and the second drive wheel 8012, the second drive wheel 8012 pulls the first drive wheel 12 to rotate through the drive rope 11. The rotation of the first drive wheel 12 drives the screw sleeve 10 fixedly connected to it to rotate. The screw sleeve 10 is threadedly matched with the screw 403, thereby pushing the screw 403 to move. When the screw 403 moves, it pushes the slide plug 402 to slide. At this time, the slide plug 402 will push the clean water in the drive cylinder 4 out. The clean water is finally sprayed out through the nozzle 901 on the connecting plate 9 to cool the grinding roller 8011 and suppress dust emission.

[0027] Limiting plates 7 are fixedly connected to both the lead screw 403 and the limiting rod 404.

[0028] By setting the limiting plate 7 on the lead screw 403 and the limiting rod 404, it is ensured that the limiting rod 404 will not slide excessively and fall into the drive cylinder 4.

[0029] Reference Figure 5 In practice, the drive rope 11 is an elastic tension rope.

[0030] By setting the drive rope 11 as an elastic pull rope, the drive rope 11 will not be broken when the second drive wheel 8012 moves up and down with the drive plate 13.

[0031] A hanging plate 201 is slidably connected to the bracket 2, an electric push rod 2011 is fixedly connected to the hanging plate 201, and a pressure plate 2012 is fixedly connected to the drive end of the electric push rod 2011.

[0032] In practice, the electric push rod 2011 pushes the pressure plate 2012 down, thereby pressing down the injection molded part on the support plate 3, thus preventing the injection molded part from sliding during the deburring process and ensuring the stability of the injection molded part during the deburring process.

[0033] Reference Figure 2 , Figure 3 It should be noted that the sliding of the hanging plate 201 can be propelled by a commercially available electric telescopic rod.

[0034] This invention uses a drive motor 8 to rotate the grinding roller 8011 on the rotating rod 801, which can effectively remove burrs from the surface of the injection molded part. During the grinding process, the rotating rod 801 can pull the first drive wheel 12 to rotate through the second drive wheel 8012, which in turn pushes the slide plug 402 to slide back and forth. The drive cylinder 4 draws water from the water tank 6 to spray and cool the grinding roller 8011, thereby effectively extending the service life of the grinding roller 8011. At the same time, by spraying clean water during the grinding process, the dust emission during the grinding process can be effectively suppressed.

[0035] It should be noted that the drive motor 8 is a commercially available servo motor.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
