[0002] Injection molding is a widely used manufacturing process for various plastic products, including the long, soft rubber sections of tool handles or yoga mats made of TPE. The smoothness and cleanliness of their surfaces are important quality indicators. Burrs on the long, soft rubber sections of tool handles or yoga mats made of TPE can affect the product's appearance, feel, and may even impact its function and lifespan.

[0003] In existing technologies, when removing burrs from the long strip of soft rubber on a tool handle or from a yoga mat made of TPE, a grinding disc is typically used to polish the surface of the tool handle or the yoga mat. However, when using a grinding disc to remove burrs, uneven surfaces or improper pressure adjustment can cause excessive pressure on certain parts of the tool handle or the yoga mat, resulting in wrinkles and hindering subsequent burr removal. Furthermore, the removed burrs tend to adhere to the surface of the tool handle or the yoga mat, leading to incomplete burr removal and affecting processing quality.

[0004] Therefore, it is necessary to propose an automatic burr removal device for injection-molded soft rubber to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic burr removal device for injection-molded soft rubber, which solves the problem that when using a grinding disc to remove burrs, uneven surface of the grinding disc or improper pressure adjustment can cause excessive compression on the long strip of soft rubber on the tool handle or certain parts of the TPE yoga mat, resulting in excessive stress in some areas and wrinkles, which is not conducive to the subsequent burr removal process. Furthermore, during burr removal, the removed burrs tend to adhere to the long strip of soft rubber on the tool handle or the surface of the TPE yoga mat, resulting in incomplete burr removal and affecting processing quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic burr removal device for injection-molded soft rubber, comprising a base, with fixed plates fixedly installed on both sides of the top of the base, hollow sleeves fixedly provided at both ends of the two fixed plates, a connecting plate fixedly installed between every two adjacent hollow sleeves, an electric push rod fixedly installed on each connecting plate, a sliding plate fixedly connected to the output end of each electric push rod, a sharp cutting edge provided on the sliding plate, a feed groove provided on one side of the sliding plate, and a processing plate movably installed at the bottom of the sliding plate.

[0007] Preferably, one side of the sliding plate is inclined, the sliding plate has a hollow structure, a mounting base is fixedly installed inside the sliding plate, a first motor is fixedly installed on the mounting base, and a fan is fixedly installed on the output end of the first motor.

[0009] Preferably, a fixed base is fixedly installed on the top of the base, and there are four fixed bases. A second motor is fixedly installed on two of the fixed bases, and a worm gear is fixedly installed on the output end of each of the two second motors. The two ends of the worm gear are respectively rotatably installed on the corresponding fixed base.

[0010] Preferably, both ends of the two worm gears are meshed with worm wheels, and each of the four worm wheels is fixedly mounted with a threaded post. The threaded post is rotatably mounted on the hollow sleeve, and a movable block is threadedly mounted on the threaded post. A connecting rod is fixedly mounted on one side of the movable block. The connecting rod is fixedly connected to one side of the processing plate. A sliding groove is provided on one side of the hollow sleeve, and the connecting rod is slidably mounted on the sliding groove.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] The sliding plate slides across the long, soft rubber section of the tool handle or the surface of a yoga mat made of TPE on the processing plate, thus smoothing out the wrinkles on the tool handle or the surface of the yoga mat made of TPE.

Detailed Implementation

[0017] 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.

[0018] This utility model provides, for example Figures 1-3 The device shown is an automatic burr removal device for injection-molded soft rubber, including a base 1. Fixing plates 2 are fixedly installed on both sides of the top of the base 1. Hollow sleeves 3 are fixedly installed on the opposite sides of the two fixing plates 2. The hollow sleeves 3 are symmetrically arranged on the same fixing plate 2. A connecting plate 4 is fixedly installed between every two adjacent hollow sleeves 3. An electric push rod 5 is fixedly installed on each connecting plate 4. A sliding plate 6 is fixedly connected to the output end of each electric push rod 5. A feed groove 7 is provided on one side of the sliding plate 6. A processing plate 8 is movably installed at the bottom of the sliding plate 6.

[0019] During operation, the long strip of soft rubber on the tool handle or a yoga mat made of TPE is laid on the upper surface of the processing plate 8. Due to prolonged use of the mold, wear, deformation, uneven parting surface, or improper injection molding process parameters, the injection-molded workpiece has a large number of burrs on its surface. These burrs need to be removed during subsequent processing. Therefore, after removing the burrs from the long strip of soft rubber on the tool handle or the yoga mat made of TPE, when wrinkles appear on the surface of the long strip of soft rubber on the tool handle or the yoga mat made of TPE on the processing plate 8, the electric push rod 5 is activated. The electric push rod 5 pushes the sliding plate 6 along the long strip of soft rubber on the tool handle or... The sliding plate 6 moves across the surface of the yoga mat made of TPE. A sharp cutting edge is provided on the long, soft rubber section of the tool handle or the yoga mat surface. The sliding plate 6 can smooth out wrinkles on the long, soft rubber section of the tool handle or the yoga mat surface, thus facilitating the removal of burrs from the surface of the tool handle or the yoga mat surface by the sharp cutting edge. While the sliding plate 6 slides across the long, soft rubber section of the tool handle or the yoga mat surface, the removed burrs are collected by the feed groove 7 on one side of the sliding plate 6, preventing the attached burrs from affecting subsequent burr removal and improving processing quality.

[0020] One side of the sliding plate 6 is inclined, and the sliding plate 6 has a hollow structure. A mounting base 9 is fixedly installed inside the sliding plate 6. A first motor 10 is fixedly installed on the mounting base 9. A fan 11 is fixedly installed on the output end of the first motor 10. A protective mesh cover is provided inside the sliding plate 6. The first motor 10 and the fan 11 are located inside the protective mesh cover. A ventilation opening 12 is provided on the side of the two sliding plates 6 that is far apart from each other. The fan 11 is positioned facing the ventilation opening 12.

[0021] When the removed burrs are collected through the feed trough 7, the first motor 10 fixedly installed on the mounting base 9 is started. The first motor 10 drives the fan 11 to rotate. The air generated by the fan 11 is discharged through the vent 12, thereby reducing the atmospheric pressure on one side of the feed trough 7, speeding up the efficiency of the feed trough 7 in collecting the removed burrs, improving the processing quality, and setting a protective net cover to prevent burrs from getting tangled in the fan blades and causing the fan to be unable to rotate.

[0022] A fixed base 13 is fixedly installed on the top of the base 1. There are four fixed bases 13. Two of the fixed bases 13 are fixedly installed with a second motor 19. A worm gear 14 is fixedly installed on the output end of each of the two second motors 19. The two ends of the worm gear 14 are rotatably installed on the corresponding fixed base 13. The two ends of the two worm gears 14 are meshed with worm wheels 15. A threaded post 16 is fixedly installed on each worm wheel 15. The threaded post 16 is rotatably installed on the cavity sleeve 3. A moving block 17 is threadedly installed on each threaded post 16. A connecting rod 20 is fixedly installed on one side of each moving block 17. The connecting rod 20 is fixedly connected to one side of the processing plate 8. A sliding groove 18 is provided on one side of each cavity sleeve 3. The connecting rod 20 is slidably installed on the sliding groove 18.

[0023] Before deburring, the second motor 19 is started, which drives the worm gear 14 to rotate. Since the worm gear 14 meshes with the worm wheel 15, it drives the threaded post 16 on the worm wheel 15 to rotate on the hollow sleeve 3. Because the moving block 17 has threads that match the threaded post 16, when the moving block 17 moves on the threaded post 16, the connecting rod 20 on one side of the moving block 17 drives the processing plate 8 to move, so that the long strip of soft rubber part of the tool handle or the yoga mat made of TPE on the processing plate 8 is in close contact with the sliding plate 6, which facilitates the processing of the long strip of soft rubber part of the tool handle or the yoga mat made of TPE.

[0024] Working principle: Before deburring, the second motor 19 is started, driving the worm gear 14 to rotate. Since the worm gear 14 meshes with the worm wheel 15, it drives the threaded post 16 on the worm wheel 15 to rotate on the hollow sleeve 3. Because the moving block 17 has threads matching the threaded post 16, when the moving block 17 moves on the threaded post 16, the connecting rod 20 on one side of the moving block 17 drives the processing plate 8 to move, causing the long strip of soft rubber part of the tool handle or the yoga mat made of TPE on the processing plate 8 to press tightly against the sliding plate 6. When wrinkles appear on the long strip of soft rubber part of the tool handle or the surface of the yoga mat made of TPE on the processing plate 8, they are connected by the connecting plate... The electric push rod 5 on the tool 4 drives the sliding plate 6 to slide on the long strip of soft rubber part of the tool handle or the surface of the yoga mat made of TPE. This causes the sliding plate 6 to smooth out the wrinkles on the long strip of soft rubber part of the tool handle or the surface of the yoga mat made of TPE, making it easier for the sharp edge on the sliding plate 6 to remove burrs from the long strip of soft rubber part of the tool handle or the surface of the yoga mat made of TPE. While the sliding plate 6 is sliding on the long strip of soft rubber part of the tool handle or the surface of the yoga mat made of TPE, the removed burrs are collected by the feed groove 7 set on one side of the sliding plate 6, so as to avoid the attached burrs affecting the subsequent burr removal and improve the processing quality.
