Description

Technical Field

[0001] This utility model belongs to the technical field of grinding equipment, specifically relating to a burr removal device for injection molded parts. Background Technology

[0002] In modern industrial production, injection molded parts, as crucial components, play an indispensable role in various fields such as automobile manufacturing, electronics, and machinery. Particularly in the production of automotive battery casings, the quality of injection molded parts directly impacts product performance and safety. However, burrs generated during the injection molding process have always been a significant factor affecting product quality. Especially for components like automotive battery casings, which require extremely high surface finishes, all four edges and surfaces need meticulous grinding to remove burrs and unevenness, ensuring optimal product appearance and performance.

[0003] Traditional deburring methods often rely on manual grinding, which is not only inefficient but also makes it difficult to guarantee the grinding effect. Furthermore, because automotive battery casings have four edges and surfaces, the grinding workload is large, requiring highly skilled workers and increasing production costs and quality control difficulties. Therefore, developing a highly efficient, automated, and high-precision deburring device for injection molded parts is particularly important. Utility Model Content

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

[0005] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A burr removal device for injection molded parts includes a base and a conveyor belt. Two sets of side polishing mechanisms are installed on the upper side of the base, and each set of side polishing mechanisms includes two conveyor belts.

[0007] The side polishing mechanism includes an inclined support frame. Two conveyor belts are spaced apart vertically and installed at an incline in the middle of the support frame. Multiple rollers rotatably connected to the support frame are installed at intervals on both the front and rear sides of the lower conveyor belt. Polishing machines are installed on both the left and right sides of the conveyor belt. The polishing machines are slidably connected to the support frame. A spring connects the polishing machines to the support frame. Protective plates are symmetrically installed on the left and right sides of the support frame. The protective plates are fixedly connected to the support frame and the polishing machines do not interfere with each other. The two sets of side polishing mechanisms are staggered vertically. The lower side of the upper support frame is connected to the upper side of the lower support frame. The lower side polishing mechanism is connected to an edge grinding device.

[0008] The edge grinding equipment includes an annular frame fixedly connected to the base. Vertical plates spaced apart are fixedly installed around the four sides of the annular frame. Mounting seats with angles to the vertical plates are installed on the upper sides of the four corners of the annular frame. A concave arc-shaped grinding wheel is rotatably mounted on the upper side of each mounting seat. A motor is mounted on the side of the mounting seat, and the output end of the motor is connected to the concave arc-shaped grinding wheel. A matching base plate is installed inside the four vertical plates. An electric telescopic rod is installed on the upper side of the base, and the output end of the electric telescopic rod is connected to the base plate. An inlet is provided on the side of the edge grinding equipment near the lower support frame.

[0009] A guide plate that slopes from top to bottom and to the left is connected to the lower side of the vertical plate on the left side, and a vertical blocking plate is fixed to the left side of the base plate.

[0010] Connecting rods distributed front and back are installed on both the left and right sides of the conveyor belt located on the upper side. A sliding groove matching the connecting rod is installed on the upper side of the annular frame, and the connecting rod is slidably connected to the sliding groove.

[0011] A baffle is fixed to the upper front part of the support frame located on the lower side, and buffer pads are installed on the rear side of the baffle and the inner side of the vertical plate located on the right side.

[0012] Two sets of side polishing mechanisms are staggered and vertically distributed, forming a three-dimensional polishing path channel together with the rollers and guard plates. This facilitates the device to quickly grind and polish the burrs on the front, back, left, and right sides of the injection molded parts, thereby reducing the labor intensity of workers and improving the product precision of the injection molded parts. The polishing machines sliding on the left and right sides of the support frame and the springs provide pressure to the polishing machines, ensuring the polishing effect. The edge grinding equipment can simultaneously grind and polish the four edges of the plastic shell, improving the grinding efficiency of the device. The edge grinding equipment, through the design of the concave arc grinding wheel and the electric telescopic rod, can accurately process the edges of the injection molded parts, removing burrs and sharp edges, making the product smoother and safer. The electric telescopic rod can precisely control the position and height of the concave arc grinding wheel, realizing the edge grinding. Precise control of the angle grinding process further enhances automation. The guide plate facilitates the accurate introduction of the injection molded part into the inner side of the vertical plate as the base plate lifts it. The blocking plate prevents new injection molded parts on the left side from sliding into the electric telescopic rod when the base plate is on top, ensuring stability and accuracy during transmission. The design of the connecting rod and slide groove allows the upper conveyor belt to cleverly use its own weight to compress the injection molded parts passing over the upper and lower sides, increasing friction while making the side polishing mechanism simple and reliable, reducing maintenance costs. Buffer pads and baffles not only protect the injection molded parts during transmission but also reduce noise and vibration caused by collisions, improving the equipment's durability and stability.

[0020] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-5 As shown, a burr removal device for injection molded parts includes a base 1 and a conveyor belt 2, characterized in that: two sets of side polishing mechanisms are installed on the upper side of the base 1, and each set of side polishing mechanisms includes two conveyor belts 2.

[0022] The side polishing mechanism includes an inclined support frame 3, two conveyor belts 2 are distributed vertically and inclinedly installed in the middle of the support frame 3, multiple rollers 4 that are rotatably connected to the support frame 3 are installed at intervals on both the front and rear sides of the lower conveyor belt 2, and polishing machines 5 are installed on both the left and right sides of the conveyor belt 2. The polishing machines 5 are slidably connected to the support frame 3, and a spring 6 is connected between the polishing machines 5 and the support frame 3. Protective plates 7 are symmetrically installed on the left and right sides of the support frame 3. The protective plates 7 are fixedly connected to the support frame 3 and the polishing machines 5 do not interfere with each other. The two sets of side polishing mechanisms are staggered vertically. The lower side of the upper support frame 3 is connected to the upper side of the lower support frame 3. The side polishing mechanism on the lower side is connected to an edge grinding device.

[0023] In use, the battery casing injection molded part that needs to be polished is placed from the top of the support frame 3. Under the action of the roller 4 and the guard plate 7, the injection molded part slides between the conveyor belts. The two conveyor belts 2 distributed vertically move the injection molded part forward. At this time, the polishing machines 5 on the left and right sides polish the left and right sides of the injection molded part. Then, it slides out from the roller 4 on the front side of the conveyor belt 2 and slides into the roller 4 on the upper left side of the side polishing mechanism located on the lower side. Finally, the injection molded part is polished and ground on both the front and back sides by the side polishing mechanism located on the lower side to remove burrs.

[0024] Two sets of side polishing mechanisms are staggered and vertically distributed, forming a three-dimensional polishing path channel together with roller 4 and guard plate 7. This facilitates the device to quickly grind and polish the burrs on the front and back sides and left and right sides of the injection molded parts, thereby reducing the labor intensity of workers and improving the product precision of injection molded parts. The polishing machine 5 and spring 6 sliding on the left and right sides of the support frame 3 provide pressure for the polishing machine 5 to ensure the polishing effect. The edge grinding equipment can grind and polish the four edges of the plastic shell at the same time, improving the grinding efficiency of the device.

[0025] The edge grinding equipment includes an annular frame 8 fixedly connected to the base 1. Vertical plates 9 are fixedly installed around the annular frame 8. Mounting seats 10 with angles to the vertical plates 9 are installed on the upper sides of the four corners of the annular frame 8. A concave arc-shaped grinding wheel 11 is rotatably mounted on the upper side of the mounting seat 10. A motor 12 is mounted on the side of the mounting seat 10. The output end of the motor 12 is connected to the concave arc-shaped grinding wheel 11. A matching base plate 13 is installed on the inner side of the four vertical plates 9. An electric telescopic rod 14 is installed on the upper side of the base 1. The output end of the electric telescopic rod 14 is connected to the base plate 13. An inlet 15 is opened on the side of the edge grinding equipment near the support frame 3 located on the lower side.

[0026] When the edge grinding equipment is working, the injection molded part enters through the inlet 15 and enters the upper side of the base plate 13. It is then pushed upward by the extension and retraction of the electric telescopic rod 14, and the four concave arc-shaped grinding wheels 11 can grind the injection molded part.

[0027] The edge grinding equipment, through the design of the concave arc-shaped grinding wheel 11 and the electric telescopic rod 14, can accurately process the edges of injection molded parts, remove burrs and sharp edges, and make the products smoother and safer. The electric telescopic rod 14 can accurately control the position and height of the concave arc-shaped grinding wheel 11, realize precise control of the edge grinding process, and further improve the degree of automation.

[0028] A guide plate 16 that slopes from top to bottom and to the left is connected to the lower side of the vertical plate 9 on the left side, and a vertical blocking plate 17 is fixed to the left side of the base plate 13.

[0029] The guide plate 16 can easily guide the injection molded part to the inside of the vertical plate 9 when the base plate 13 drives the injection molded part to rise. The blocking plate 17 can prevent the new injection molded part on the left side from sliding into the inside of the electric telescopic rod 14 when the base plate 13 is on the upper side, thus ensuring the stability and accuracy of the injection molded part during the transmission process.

[0030] Connecting rods 18 are installed on both the left and right sides of the upper conveyor belt 2, and sliding grooves matching the connecting rods 18 are installed on the upper side of the annular frame. The connecting rods 18 and the sliding grooves are slidably connected up and down.

[0031] The design of the connecting rod 18 and the slide groove allows the upper conveyor belt 2 to cleverly use its own weight to squeeze the injection molded parts passing through the upper and lower sides, increasing the friction with the injection molded parts while making the side polishing mechanism simple and reliable, and reducing maintenance costs.

[0032] A baffle 20 is fixed to the upper front of the support frame 3 located on the lower side, and buffer pads 21 are installed on the rear side of the baffle 20 and the inner side of the vertical plate 9 located on the right side.

[0033] Buffer pads 21 and baffles 20: These designs not only protect the injection molded parts during transport, but also reduce noise and vibration caused by collisions, improving the durability and stability of the equipment.

[0034] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
