Technical Field
[0001] The invention mainly relates to the technical field of injection molded parts processing, in particular to an injection molded parts burr removal and marking tool. Background Art
[0002] Injection molding is an important process in the plastic processing industry. It injects molten plastic into a mold and cools and solidifies it to obtain a plastic product of the desired shape. However, during the injection molding process, due to the influence of various factors such as mold design, injection molding machine parameter settings, and plastic material properties, excess plastic burrs (also known as flash or flash) often appear on the edges of injection molded parts. These burrs not only affect the appearance quality of the product, but may also have an adverse effect on the functional performance and safety of the product. In order to improve the product quality of injection molded parts and meet market demand, the deburring process has become an indispensable part after injection molding.
[0003] Traditional deburring methods include manual stripping, freezing, and aerodynamic trimming. Manual deburring is time-consuming, labor-intensive, and inefficient, and it is difficult to meet the needs of large-scale production. Although automated deburring methods such as freezing and aerodynamic trimming can improve efficiency, the equipment cost is high, and the deburring effect is not ideal for injection molded parts with complex shapes.

The threaded rod 18 is rotatably arranged in the shell 17. The lifting slider 1901 is sleeved on the threaded rod 18. The rotating handle 9 is rotatably arranged on the top of the shell 17, and its bottom is fixedly connected to the top of the threaded rod 18. By rotating the rotating handle 9, the rotating handle 9 drives the threaded rod 18 to rotate, so that the lifting slider 1901 is lifted and lowered, so as to control the distance between the first grinding wheel 6 and the second grinding wheel 7, so as to grind injection molded parts of different sizes.
[0026] The specific operation process of the present invention is as follows: First, the injection molded part is clamped by the clamping structure 3. The clamping structure 3 is composed of symmetrically distributed placement plates 12. An electromagnetic slider 15 is installed at the bottom of each placement plate 12. The electromagnetic slider 15 can slide flexibly along the slide bar 2 to drive the clamped injection molded part to perform edge removal and marking. A shell 13 is installed on the top of the placement plate 12. An array of clamping rods 1301 are arranged in the shell 13. The clamping rod 1301 is retracted and extended by a sliding mechanism in the shell 13 to adapt to injection molded parts of different shapes and sizes. The setting of the locking handle 14 ensures the stability and reliability of the clamping rod 1301 during the clamping process. By rotating the locking handle 14, the clamping rod 1301 can firmly clamp the injection molded part, which not only ensures the stability of the clamping, but also avoids damage to the product. Secondly, after the injection molded parts are firmly clamped, they are transported to the grinding and deburring structure for deburring. The grinding and deburring structure consists of a first grinding wheel 6 and a second grinding wheel 7, which are symmetrically distributed up and down and are driven by a first motor 10 and a second motor 11 respectively. The first motor 10 is connected to the lifting structure 5 through a connecting plate 19. The rotation of the threaded rod 18 can be adjusted by rotating the handle 9, thereby controlling the lifting and lowering of the lifting slider 1901, thereby adjusting the distance between the first grinding wheel 6 and the second grinding wheel 7 to accommodate injection molded parts of different sizes. When the injection molded parts are sent between the first grinding wheel 6 and the second grinding wheel 7 by the clamping structure 3, the two work simultaneously to accurately control the grinding force and range, effectively remove the burrs on the edges of the injection molded parts, and protect the surface quality of the product at the same time; Finally, after the deburring process is completed, the clamping structure 3 continues to drive the injection molded part to move to one side of the marking structure 4. The marking end 21 is connected to the control end 8 through the connecting line 23, and the marking head 22 is installed on one side of the marking end 21. After the clamping structure 3 drives the injection molded part to the specified position, the driving rod 16 contacts the driven head 2401 in the guide block 20 and pushes the driven block 24 to move. The driven block 24 drives the driving block 25 to move through the connecting rod 26, so that the driving head 2501 at one end of the driving block 25 contacts the trigger head 2101. After receiving the contact signal, the trigger head 2101 sends a start signal to the control end 8, and the control end 8 then transmits the marking signal to the marking end 21 through the connecting line 23. After receiving the signal, the marking head 22 starts the laser beam to perform precise laser marking on the outer wall of the injection molded part. Since the clamping structure 3 can ensure the stability of the injection molded part during the marking process, the marking structure 4 can more accurately control the focus and movement path of the laser beam, thereby forming a clear and lasting mark on the outer wall of the injection molded part.

It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
