[0002] Injection molding is a manufacturing method for industrial products, typically using rubber injection molding and plastic injection molding. It involves injecting thermoplastic material into a mold to create plastic products of various shapes. When the plastic product is in its blank state, some burrs exist on its surface. This is because there is a gap between the two molds, and some of the plastic fluid fills this gap as it fills the mold cavity, resulting in burrs on the molded plastic product blank.

[0003] A search revealed Chinese Patent Publication No. CN220783325U, which discloses a device for treating rough edges on plastic buckets. The device includes a clamping base, an adjusting structure, a sliding plate, a first motor, and a grinding structure. The adjusting structure is fixed to the top of the clamping base, and the sliding plate is slidably connected to the outer wall of the adjusting structure. The first motor is fixed to the top of the sliding plate, and its output shaft passes through the sliding plate and is fixedly connected to the grinding structure. In use, the manufactured plastic bucket is fixed inside the clamping base. The height of the sliding plate is adjusted according to the height of the bucket using the adjusting structure. The first motor drives the grinding structure to grind the top edge of the plastic bucket. This device is adaptable to plastic buckets of different sizes and has strong versatility.

[0004] However, when using the aforementioned patent, fixing and detaching the plastic bucket requires adjusting the clamping base and the structure, and replacing the plastic bucket takes a lot of time, thus reducing work efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a device for trimming burrs on injection molded parts, which aims to improve the problem of the device being fixed and detached from the plastic bucket, making it troublesome to replace the plastic bucket.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for trimming burrs on injection molded parts, comprising a bracket, a control motor fixedly connected to the top of the bracket, a fixed frame fixedly connected to the output end of the control motor, a first gear rotatably connected to the inner wall of the fixed frame, a plurality of supporting rack frames meshing with the tooth ends of the first gear, a first spring provided on the far side of two supporting rack frames, a support block slidably connected to the outer wall of the supporting rack frame, a first bevel gear fixedly connected to the bottom of the first gear, a second bevel gear meshing with the tooth ends of the first bevel gear, a second gear fixedly connected to the outer wall of the second bevel gear, a sliding rack frame meshing with the tooth ends of the second gear, a second spring provided at the top of the sliding rack frame, an electric push rod fixedly connected to the bottom of the bracket, a rotating chuck rotatably connected to the top of the electric push rod, and an adjustment component provided on the right side of the bracket.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, an electric push rod pushes a rotating chuck and a plastic bucket upwards, causing the bottom of the inner wall of the plastic bucket to first contact the sliding rack and drive the sliding rack and drive it upwards. Then, the top of the plastic bucket contacts the outer wall of the fixed frame, causing multiple support blocks to move outwards through the sliding rack and contact the inner wall of the plastic bucket, thus fixing the plastic bucket between the fixed frame and the rotating chuck. The electric push rod drives the rotating chuck downwards, allowing the sliding rack and drive to push the plastic bucket downwards through the elastic force of the second spring. At the same time, multiple support blocks leave the inner wall of the plastic bucket, allowing the plastic bucket to move downwards with the rotating chuck, achieving the effect of conveniently fixing and detaching the plastic bucket.

[0016] 2. In this utility model, the rotation of the electric fan generates a downward suction force through the filter screen of the sliding frame and the collection box, thereby sucking the burrs and debris generated by the trimming tool and the plastic bucket into the collection box through the movable connecting pipe for collection. This prevents the burrs and debris from remaining on the surface of the device and the plastic bucket, thus achieving the effect of convenient burr and debris cleaning. Attached Figure Description

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a device for trimming burrs on injection molded parts, comprising a bracket 1, a control motor 2 fixedly connected to the top of the bracket 1, a fixed frame 3 fixedly connected to the output end of the control motor 2, a first gear 4 rotatably connected to the inner wall of the fixed frame 3, a plurality of support rack frames 5 meshing with the tooth ends of the first gear 4, a first spring 6 provided on the far side of two support rack frames 5, a support block 7 slidably connected to the outer wall of the support rack frame 5, a first bevel gear 8 fixedly connected to the bottom end of the first gear 4, a second bevel gear 9 meshing with the tooth ends of the first bevel gear 8, and a second bevel gear 9 being connected to the outer wall of the second bevel gear 9. A second gear 10 is fixedly connected to the wall, and a sliding rack frame 11 is meshed with the tooth end of the second gear 10. A second spring 12 is provided at the top of the sliding rack frame 11. An electric push rod 14 is fixedly connected to the bottom of the bracket 1. A rotating chuck 13 is rotatably connected to the top of the electric push rod 14. An adjustment assembly is provided on the right side of the bracket 1. The adjustment assembly includes a sliding frame 18, which is slidably connected to the outer wall of the bracket 1. A movable frame 16 is slidably connected to the outer wall of the sliding frame 18. Fixing bolts 17 are threadedly connected to both the front and rear sides of the movable frame 16. A dressing tool 15 is slidably connected to the inner wall of the movable frame 16.

[0027] Specifically, by rotating the two fixing bolts 17, the trimming tool 15 slides left and right on the inner wall of the movable frame 16, and the movable frame 16 slides up and down on the outer wall of the sliding frame 18. This allows the trimming tool 15 to be moved according to the size of the plastic bucket. After moving the trimming tool 15 to a suitable position, the fixing bolts 17 are rotated to fix the position of the trimming tool 15, thus achieving the effect of adjusting the trimming tool 15. Through the electric push rod 14, the top of the plastic bucket contacts the fixed frame 3, and its bottom contacts the sliding rack frame 11. The sliding rack frame 11 moves upward, indirectly causing the four support blocks 7 to contact the inner wall of the plastic bucket, thereby fixing the plastic bucket. The drive control motor 2 drives the fixed frame 3 and the plastic bucket to rotate, allowing the trimming tool 15 to trim the rough edges of the plastic bucket. Then, the rotating chuck 13 is lowered, and the sliding rack frame 11, through the elastic force of the second spring 12, allows the plastic bucket to detach from the fixed frame 3, thus achieving the effect of facilitating the installation and removal of the plastic bucket.

[0028] Reference Figure 3 and Figure 6 An electric fan 19 is rotatably connected to the inner wall of the sliding frame 18, and a collection box 20 is slidably connected to the outer wall of the sliding frame 18. A movable connecting pipe 21 is slidably connected to the top of the collection box 20, and the movable connecting pipe 21 is fixedly connected to the outer wall of the dressing tool 15.

[0029] Specifically, the bottom end of the electric fan 19 is rotatably connected to the front inner wall of the sliding frame 18, the bottom outer wall of the collection box 20 is slidably connected to the front outer wall of the sliding frame 18, and the bottom end of the movable connecting pipe 21 is slidably connected to the top of the collection box 20. By starting the electric fan 19, suction is generated, which causes the burrs and debris trimmed by the trimming tool 15 to be sucked into the collection box 20 through the movable connecting pipe 21, thereby achieving the effect of effectively cleaning the debris.

[0030] Reference Figure 2 and Figure 6 The fixed frame 3 is rotatably connected to the outer wall of the bracket 1, and the rotating chuck 13 is rotatably connected to the outer wall of the sliding frame 18.

[0031] Specifically, the rotating chuck 13 pushes the plastic bucket upward through the electric push rod 14 to fix it to the outer wall of the fixed frame 3. When the control motor 2 drives the fixed frame 3 to rotate, the rotating chuck 13 and the plastic bucket can rotate together, which makes it convenient for the trimming tool 15 to trim the rough edges of the plastic bucket.

[0032] Reference Figure 4 and Figure 5 The second bevel gear 9 is rotatably connected to the inner wall of the fixed frame 3, the second spring 12 is disposed on the inner wall of the fixed frame 3, and the sliding rack frame 11 is slidably connected to the inner wall of the fixed frame 3.

[0033] Specifically, by moving the sliding rack frame 11 upward, the second spring 12 is compressed, so that the rack at its top can drive the second bevel gear 9 to rotate inside the fixed frame 3 through the second gear 10. Through the elastic force of the second spring 12, the sliding rack frame 11 can push the plastic bucket downward, thereby facilitating the detachment of the plastic bucket.

[0034] Reference Figure 4 and Figure 5 Multiple support rack frames 5 are slidably connected to the inner wall of the fixed frame 3, and the first bevel gear 8 is rotatably connected to the inner wall of the fixed frame 3.

[0035] Specifically, the first bevel gear 8 drives the first gear 4 to rotate through the second gear 10, so that the support rack frame 5 can slide outward by the rack meshing with the first gear 4, thereby facilitating the fixing of the plastic bucket.

[0036] Reference Figure 4 and Figure 5Multiple support blocks 7 are slidably connected to the inner wall of the fixed frame 3, and the first spring 6 is disposed on the inner wall of the support block 7.

[0037] Specifically, the support block 7 can move outward by moving upward through the sliding rack 11, and move inward by moving downward through the sliding rack 11. The first spring 6 can prevent the support block 7 from moving outward too much and causing the plastic bucket to crack.

[0038] Reference Figure 6 One of the fixing bolts 17 is threaded to the inner wall of the moving frame 16 and contacts the dressing tool 15, and another fixing bolt 17 is threaded to the inner wall of the moving frame 16 and contacts the sliding frame 18.

[0039] Specifically, by rotating the two fixing bolts 17, the fixing bolts 17 are moved away from the dressing tool 15 and the sliding frame 18, which allows the dressing tool 15 to move left and right and the sliding frame 16 to move up and down. By rotating the front fixing bolt 17, the fixing bolt 17 is brought into contact with the dressing tool 15 and the sliding frame 18, which allows the dressing tool 15 to be fixed on the sliding frame 16 and the sliding frame 16 to be fixed on the sliding frame 18, thereby achieving the effect of adjusting the position of the dressing tool 15.

[0040] Working principle: The plastic bucket is placed on the positioning teeth of the rotating chuck 13. By rotating the two fixing bolts 17, the trimming tool 15 is moved to the rough edge of the plastic bucket and fixed. Then, the electric push rod 14 is activated, which pushes the rotating chuck 13 and the sliding frame 18 upward, so that the bottom of the inner wall of the plastic bucket contacts the sliding rack frame 11. The sliding rack frame 11 moves upward, and after the top of the plastic bucket contacts the outer wall of the fixing frame 3, the upper and lower ends of the plastic bucket are clamped between the fixing frame 3 and the rotating chuck 13. The four support blocks 7 move upward through the sliding rack frame 11, so that their outer walls contact the inner wall of the plastic bucket, fixing the plastic bucket between the fixing frame 3 and the rotating chuck 13. Then, the control motor 2 is activated to drive... The fixed frame 3 rotates, thereby causing the plastic bucket and the rotating chuck 13 to rotate, allowing the trimming tool 15 to trim the rough edges of the plastic bucket. The resulting rough edge debris is sucked into the collection box 20 by the electric fan 19 through the movable connecting pipe 21, thus facilitating the cleaning of debris. After the rough edges of the plastic bucket are trimmed, the control motor 2 is stopped, and the electric push rod 14 is started to drive the rotating chuck 13 and the sliding frame 18 to move downward. The sliding rack frame 11 pushes the plastic bucket downward by the elastic force of the second spring 12. At the same time, the four support blocks 7 move inward, causing their outer walls to separate from the inner walls of the plastic bucket, allowing the plastic bucket to move downward with the rotating chuck 13, thus facilitating the fixing and detachment of the plastic bucket.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
