Description

When the injection molded parts are just injection molded, there is usually a sprue structure formed by the injection channel on their surface. In particular, when the injection channel of some products is large, the sprue structure formed will also be relatively large. Therefore, before becoming a formal product, these sprues and other useless structures need to be polished and trimmed to remove these useless parts.

[0003] In the Chinese patent with publication number CN222021289U, a device for trimming injection molded parts is mentioned, which effectively drives the movable plate to move downward by a hydraulic cylinder until the grinding disc below the movable plate contacts the side surface of the injection molded part, and then starts the first motor, which effectively drives the grinding disc to rotate, thereby achieving the grinding and trimming of the injection molded part by the grinding disc;

[0004] However, when the processing equipment is in use, the grinding disc is fixed in position and can only be moved up and down to trim the overflow of injection molded parts in fixed positions. This leads to limitations in the use of the equipment, making it inconvenient to accurately locate the overflow at different positions on the injection molded parts, thereby limiting its flexibility in trimming various overflows.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1:

[0039] See also Figures 1 to 7 As shown, a finishing and processing equipment for computer injection molding parts includes:

[0040] Recycling bin 1;

[0041] A cooling mechanism 3 is installed at the lower part of the outer wall of the recycling box 1, a clamping mechanism 4 is installed between the inner walls on both sides of the recycling box 1, support plates 5 are installed on both sides of the top of the recycling box 1, and a controller 6 is installed on the outer wall of one side of the support plate 5;

[0042] The positioning mechanism 2 includes a protective cover 21, an ultrasonic sensor 22, a visual sensor 23, a trimming mechanism 24 and a fixing rod 25. The ultrasonic sensor 22 is installed at one end of the protective cover 21, the visual sensor 23 is installed at the other end of the protective cover 21, the trimming mechanism 24 is installed on the top inner wall of the protective cover 21, and the fixing rod 25 is installed in the middle of the top end of the protective cover 21.

[0043] Depend on Figures 1 to 4 It can be seen that the top ends of the two support plates 5 are both installed with a Z-axis regulator 7, an X-axis regulator 8 is commonly installed between the top ends of the two Z-axis regulators 7, a Y-axis regulator 9 is installed on the outer wall of the X-axis regulator 8, and the outer wall of the Y-axis regulator 9 is installed together with the outer wall of the positioning mechanism 2;

[0044] Two guide strips 10 are installed between the lower parts of the opposite surfaces of the two support plates 5, and the bottom ends of the two guide strips 10 are installed at the top of the recovery box 1. A drainage pipe 11 is installed at the lower part of one end of the recovery box 1. A plurality of water inlets 12 are opened in the middle of the top of the recovery box 1. Fixed grooves 13 are opened on the upper parts of the inner walls on both sides of the recovery box 1. A filter frame 14 is installed between the two fixed grooves 13. A semiconductor cooling sheet 15 is installed in the middle of the bottom inner wall of the recovery box 1.

[0045] The dressing mechanism 24 includes a driver 241, a rotating frame 242, a grinding disc 243, a pulley set 244, an electric push rod 245 and a polishing disc 246. The driver 241 is installed at the top of the protective cover 21, the rotating frame 242 is installed on one side of the top inner wall of the protective cover 21 through a bearing, the grinding disc 243 is installed at the bottom end of the rotating frame 242, the electric push rod 245 is installed on the other side of the top inner wall of the protective cover 21 through a bearing, the pulley set 244 is installed between the outer surface of the electric push rod 245 and the outer surface of the rotating frame 242, and the polishing disc 246 is installed at the output end of the electric push rod 245.

[0046] As can be seen from the above, when the computer injection molding parts need to be trimmed, first, the injection molding parts are photographed by the visual sensor 23, and the ultrasonic sensor 22 is used to measure the distance. Combined with the captured injection molding part image and ultrasonic data, the image processing algorithm can accurately identify the position and shape of useless structures such as overflow and water outlet. Using this information, the system performs three-dimensional precise positioning of the overflow at different positions of the injection molding parts. Subsequently, the controller 6 controls the Z-axis regulator 7, the X-axis regulator 8 and the Y-axis regulator 9 to flexibly adjust the position of the positioning mechanism 2 to accurately move the grinding disc 243 to the injection molding parts. The controller 6 then starts the driver 241, causing the rotating frame 242 to drive the grinding disc 243 to perform grinding and trimming. At the same time, through the synchronous transmission of the pulley set 244, the electric push rod 245 drives the polishing disc 246 to rotate synchronously with the grinding disc 243 to polish the polished injection molded part. This process not only facilitates real-time monitoring and adjustment of the processing process, but also significantly improves the level of intelligent processing, thereby expanding the scope of use of the trimming equipment and enhancing the flexibility of the equipment. In particular, the equipment performs well in accurately trimming the overflow of injection molded parts.

[0047] Specifically, refer to Figures 1 to 4 As shown, the driver 241, the electric push rod 245, the ultrasonic sensor 22, the visual sensor 23, the Z-axis adjuster 7, the X-axis adjuster 8, the Y-axis adjuster 9 and the semiconductor refrigeration plate 15 are all electrically connected to the controller 6, the bottom end surfaces of the grinding disk 243 and the polishing disk 246 are both lower than the bottom end surface of the protective cover 21, and the fixing rod 25 is installed on the Y-axis adjuster 9.

[0048] As can be seen from the above, the controller 6 serves as the center of the entire system and is responsible for receiving instructions, processing data, and sending control signals to each device, so that when performing grinding or polishing operations, the protective cover 21 can protect the operating area from external interference, while ensuring that the grinding disk 243 and the polishing disk 246 can fully contact the surface to be processed, making it easy to flexibly adjust the position of the grinding disk 243 and the polishing disk 246.

[0049] Embodiment 2:

[0050] refer to Figure 5 and Figure 6 As shown, the cooling mechanism 3 includes a water pump 31, a filter tube 32, a water pipe 33, a diverter pipe 34 and a cooling nozzle 35. The water pump 31 is installed at the lower part of the outer wall of the recovery box 1, the filter tube 32 is installed on the outer wall of the water pump 31, the water pipe 33 is installed at the top of the water pump 31, the diverter pipe 34 is installed at the other end of the water pipe 33, and the bottom end of the diverter pipe 34 is installed at the top of the protective cover 21. A plurality of cooling nozzles 35 are provided, and the plurality of cooling nozzles 35 are all installed at the bottom end of the diverter pipe 34;

[0051] The filter tube 32 includes a water suction pipe 321, a filter frame 322, a rotating shaft 323, a driving paddle 324 and a cleaning brush 325. The water suction pipe 321 is installed on the outer wall of the water pump 31, and the outer surface of the water suction pipe 321 is fixedly connected with the inner wall of the recovery box 1 through insertion. The filter frame 322 is installed on the outer wall of the water suction pipe 321, and the rotating shaft 323 is installed in the middle of the outer wall of the filter frame 322 through a bearing. The driving paddle 324 is installed at one end of the rotating shaft 323, and the cleaning brush 325 is installed at the other end of the rotating shaft 323.

[0052] As can be seen from the above, during the process of trimming the computer injection molding parts, the controller 6 will start the water pump 31, and extract the cooling liquid in the recovery box 1 through the water pumping pipe 321. Then the cooling liquid is transported to the annular diversion pipe 34 through the water delivery pipe 33 for uniform diversion. The cooling liquid sprayed by the multiple cooling nozzles 35 directly acts on the grinding disc 243, the polishing disc 246 and the trimming parts of the injection molding parts, effectively controlling the material deformation during the trimming process, thereby maintaining the dimensional accuracy and surface quality of the injection molding parts. After the cooling is completed, the cooling liquid flows back to the return tank 1 through the water inlet 12. Receive box 1. During this process, the cooling liquid first passes through the filter frame 14 to filter out large particles of impurities, and then is cooled again by the semiconductor refrigeration plate 15. The cooled cooling liquid flows through the filter frame 322 for secondary filtration to ensure the purity of the liquid. In addition, when the cooling liquid impacts the driving paddle 324, it will drive the rotating shaft 323 to rotate, and then the cleaning brush 325 will rotate, effectively cleaning the filter on the filter frame 322, ensuring the normal filtration and circulation of the cooling liquid. This series of designs not only realizes the recycling of the cooling liquid, but also significantly saves resources.

[0053] Preferably, reference Figure 5 and Figure 6 As shown, the bristles on the cleaning brush 325 are in contact with the filter screen on the filter frame 322 , the water pump 31 is electrically connected to the controller 6 , the water pipe 33 is configured as a hose, the diversion pipe 34 is configured as a ring structure, and the cooling nozzle 35 is located inside the protective cover 21 .

[0054] As can be seen from the above, the cleaning brush 325 can clean the impurities or particles on the filter screen of the filter frame 322 to keep the filtration system unobstructed. The controller 6 can control the switch and power of the water pump 31 to adjust the water flow speed and pressure. The water pipe 33 of the hose can be flexibly bent to facilitate the delivery of water in different positions and directions. The annular structure can ensure that the water flow is evenly distributed to each cooling nozzle 35 to improve the cooling effect. The interior of the protective cover 21 is convenient for cooling the grinding disc 243 and the polishing disc 246 to prevent overheating.

[0055] Embodiment three:

[0056] refer to Figure 7 As shown, the clamping mechanism 4 includes a driving motor 41, a forward and reverse screw rod 42, an adjusting frame 43, a clamping frame 44, an electric telescopic rod 45 and a clamping plate 46. The driving motor 41 is installed on the upper part of the outer wall of the recycling box 1, the forward and reverse screw rod 42 is installed on the output end of the driving motor 41, and the forward and reverse screw rod 42 is installed between the inner walls on both sides of the recycling box 1 through bearings. There are two adjusting frames 43 and two clamping frames 44. The two adjusting frames 43 are installed on the outer surfaces of the forward and reverse screw rods 42. The two clamping frames 44 are respectively installed on the top ends of the two adjusting frames 43. There are four electric telescopic rods 45 and four clamping plates 46. The four electric telescopic rods 45 are respectively installed on the outer walls on both sides of the two clamping frames 44, and the four clamping plates 46 are respectively installed on the output ends of the four electric telescopic rods 45.

[0057] As can be seen from the above, first, the injection molded parts that need to be trimmed are placed on the top of the recycling box 1, and then the controller 6 controls the drive motor 41 to start, and the drive motor 41 drives the forward and reverse screw rods 42 to rotate, so that the two adjustment frames 43 drive the two clamping frames 44 to move stably toward the middle, and clamp the two sides of the injection molded parts. The adjustment frames 43 are slidably connected to the water inlet 12, which can improve the stability of the adjustment frames 43 during the movement. Then, the controller 6 controls the electric telescopic rod 45 to start, and the electric telescopic rod 45 extends to push the clamping plate 46 to move, and clamp the injection molded parts from the other two sides. In this way, the injection molded parts can be clamped and fixed firmly, thereby improving their stability during the trimming process. At the same time, the clamping mechanism 4 can also clamp injection molded parts of various sizes and shapes to meet the trimming requirements.

[0058] Preferably, reference Figure 7 As shown, the driving motor 41 and the electric telescopic rod 45 are both electrically connected to the controller 6 , the adjusting frame 43 and the clamping frame 44 are both configured as a U-shaped structure, and the adjusting frame 43 is slidably connected to the corresponding two water inlets 12 .

[0059] As can be seen from the above, the controller 6 can control the operation and stop of the driving motor 41, and adjust the telescopic length of the electric telescopic rod 45. The U-shaped structure of the clamping frame 44 is convenient for clamping and fixing the injection molded accessories. The water inlet 12 can limit the adjustment frame 43, thereby improving the stability of the adjustment frame 43 during the adjustment process.

[0060] Application examples:

[0061] This design is applied to the post-processing of precision injection molded parts in the plastic processing industry, especially in the field of computer hardware manufacturing. This industry has extremely high requirements for the precision, surface quality and dimensional stability of injection molded parts. Any tiny defects, such as flash (also known as flash and burrs), may affect the assembly, function and appearance of the product. This design sets a clamping mechanism 4 and uses adjustable components to clamp and fix computer injection molding accessories. It can adapt to injection molding accessories of different sizes and shapes, ensure stable clamping during the trimming process, and prevent displacement. By setting a positioning mechanism 2, an ultrasonic sensor 22 is used for distance measurement. At the same time, in combination with a visual sensor 23, image recognition technology is used to automatically identify the shape and overflow position of the injection molding accessories to achieve precise positioning. In addition, combined with three-axis (Z-axis, X-axis, Y-axis) regulators, it is convenient to flexibly trim different positions of computer injection molding accessories. By setting a cooling mechanism 3, the position where the injection molding accessories are being trimmed can be cooled, which can increase the hardness of the material and reduce deformation during the trimming process, thereby improving the trimming accuracy.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
