Description

Technical Field

[0001] This utility model relates to the technical field of injection molding processing, specifically to an injection molding burr remover. Background Technology

[0002] Many automotive parts utilize injection molding, which reduces the overall weight of the vehicle and facilitates processing. Using special materials can also enhance strength and performance. For example, carbon fiber injection molding products are manufactured using a carbon fiber injection molding process. Injection-molded automotive parts include speaker grilles, clips, speaker covers, cup holders, seat button covers, door handle boxes, door handle bases, charging docks, air intake housings, decorative panels, and skid plates. Due to factors such as the mold itself, injection parameters, and injection method, injection-molded parts may have burrs, which need to be removed after injection molding.

[0003] Currently, the most common method for deburring used by injection molding manufacturers is manual scraping. The deburring tools typically consist of a handle and a blade. While these tools are low-cost and easy to use, the scraping depth cannot be controlled. Inexperienced or inadequate users are not only prone to injury during use, but also cannot control the scraping depth and speed. Scraping too deeply will reduce product quality and may even lead to the scrapping of the injection molded product. When the scraping speed is too fast, the control over the scraping depth will decrease, limiting the scraping speed during use. Therefore, it is necessary to design a deburring tool for injection molded parts. Utility Model Content

[0004] In view of the above-mentioned technical problems, the purpose of this utility model is to overcome the problems of difficulty in controlling the scraping depth and low scraping speed in the prior art when removing burrs.

[0005] To achieve the above objectives, this utility model provides a deburr remover for injection molded parts, comprising: a mounting base, an inclined scraper detachably mounted on the mounting base, a handle fixedly connected to the mounting base, a pair of sliding auxiliary units detachably mounted on opposite outer walls of the mounting base and symmetrically arranged about the scraper, and a positioning wheel mounted on the mounting base and located behind the scraper scraping direction.

[0006] The scraper has a blade on one side of its middle section, and the positioning wheel has a positioning groove on its outer wall that is opposite to the blade. The rotation axis of the positioning wheel is perpendicular to the scraping direction of the scraper.

[0007] Preferably, the sliding auxiliary unit includes an adjusting arm rotatably mounted on a mounting base and at least two balls rotatably mounted on the adjusting arm and disposed away from the mounting base. The mounting base is equipped with a hinge portion rotatably connected to the adjusting arm, and the adjusting arm is equipped with a locking mechanism that can be detachably engaged with the hinge portion.

[0008] The rotation axis of the adjusting arm is perpendicular to both the scraping direction of the scraper and the rotation axis of the positioning wheel.

[0009] Preferably, the adjusting arm is H-shaped, with a pair of balls mounted on the two ends of the adjusting arm away from the mounting base. A mounting groove is provided through the center of the balls, and a first bolt passing through the mounting groove is threaded to the end of the adjusting arm.

[0010] Preferably, there are two hinges, and the two ends of the adjusting arm near the mounting base are respectively in contact with the outer wall of the hinge opposite to the hinge. The two ends of the adjusting arm in contact with the hinge are equipped with hinge shafts that pass through the two hinges.

[0011] The locking mechanism includes a sliding arm that slides along the axis of the hinge with the adjusting arm, and the sliding arm is detachably connected to one of the hinge parts.

[0012] Preferably, the locking mechanism further includes a first locking sleeve coaxial with the hinge shaft and sleeved on the outside of the hinge shaft and fixedly connected to the corresponding hinge part, a second locking sleeve slidably sleeved on the hinge shaft and fixedly connected to the sliding arm, and a spring sleeved on the hinge shaft for pushing the second locking sleeve to slide closer to the first locking sleeve.

[0013] The first ferrule and the second ferrule have a plurality of recessed slots evenly distributed along the circumferential direction at their contact ends, and the second ferrule has at least one protruding block portion that matches the slots.

[0014] Preferably, the mounting base includes a pair of parallel mounting plates and mounting arms that are fixedly connected to the pair of mounting plates at both ends, the mounting arms being located between the positioning wheel and the scraper;

[0015] The mounting plate has a recessed mounting groove with an open top on its opposite sidewall. The end of the scraper is slidably inserted into the mounting groove. The mounting arm is fitted with a positioning plate by several second bolts. The positioning plate can press against the side of the scraper away from the blade. The two sides of the positioning plate are slidably inserted into the corresponding mounting grooves.

[0016] Preferably, the two ends of the spring abut against the hinge portion away from the first ferrule and the second ferrule, respectively.

[0017] According to the above technical solution, the burr remover for injection molded parts provided by this utility model has the following beneficial effects during use:

[0018] Firstly, when scraping burrs off the edge of the injection molded part, the positioning wheel not only provides support to prevent the scraper from scraping too deeply, but also the edge of the injection molded part is located in the positioning groove, so the positioning groove also plays a role in positioning and preventing skewing. Otherwise, the scraper is prone to slipping when scraping, thus increasing the moving speed of the remover on the edge of the injection molded part.

[0019] Secondly, when scraping burrs on the corners of injection molded parts, a pair of sliding auxiliary units play the main role, while the positioning wheel plays an auxiliary role. After the pair of sliding auxiliary units slide into contact with the injection molded parts, they can prevent the scraper from scraping too deeply and also play a certain anti-slip role. When working together with the positioning wheel, they can further improve the anti-slip role, ensuring the quality of burr removal while improving work efficiency.

[0020] Thirdly, when scraping burrs on the corners of injection molded parts, the positioning wheels can also be used in units, which can also play a role in positioning and anti-slip.

[0021] Other features and advantages of this utility model will be described in detail in the following detailed description section; and all parts not covered in this utility model are the same as or can be implemented using existing technology. Attached Figure Description

[0030] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0031] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its normal use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0032] like Figure 1-5 As shown, an injection molding part deburr remover includes: a mounting base 1, an inclined scraper 2 detachably mounted on the mounting base 1, a handle 3 fixedly connected to the mounting base 1, a pair of sliding auxiliary units detachably mounted on the two opposite outer walls of the mounting base 1 and arranged symmetrically with respect to the scraper 2, and a positioning wheel 4 mounted on the mounting base 1 and located behind the scraper 2 in the scraping direction.

[0033] The scraper 2 has a blade 5 on one side of its middle section, and the positioning wheel 4 has a positioning groove 6 that is opposite to the blade 5 on its outer wall. The rotation axis of the positioning wheel 4 is perpendicular to the scraping direction of the scraper 2.

[0034] In the above technical solution, when scraping the burrs on the edge of the injection molded part, the pair of pulley auxiliary units do not play a role, and the positioning wheel 4 plays a major auxiliary role. The positioning wheel 4 can not only provide support to prevent the scraper 2 from scraping too deeply, but also the edge of the injection molded part is located in the positioning groove 6. Therefore, the positioning groove 6 also plays a role in positioning and preventing skew. Otherwise, the scraper 2 is prone to slipping when scraping. It increases the moving speed of the remover on the edge of the injection molded part, so that the blade 5 of the scraper 2 can face the burr when removing the burr, thus improving work efficiency.

[0035] When scraping burrs on the corners of injection molded parts, a pair of auxiliary sliding units can be adjusted so that they slide into contact with the two adjacent outer walls of the injection molded parts. At this time, the pair of auxiliary sliding units play the main role, while the positioning wheel 4 plays an auxiliary role. After the pair of auxiliary sliding units slide into contact with the injection molded parts, they can prevent the scraper 2 from scraping too deeply and also play a certain anti-slip role. When they work together with the positioning wheel 4, they can further improve the anti-slip role. At this time, the remover can quickly slide over the injection molded parts, ensuring the quality of burr removal while improving work efficiency.

[0036] When scraping burrs on the corners of injection molded parts, the positioning wheel 4 can also be used as a unit, which can also play a role in positioning and anti-slip.

[0037] In a preferred embodiment of the present invention, the sliding auxiliary unit includes an adjusting arm 7 rotatably mounted on a mounting base 1 and at least two balls 8 rotatably mounted on the adjusting arm 7 and disposed away from the mounting base 1. The mounting base 1 is equipped with a hinge part 9 rotatably connected to the adjusting arm 7, and the adjusting arm 7 is equipped with a snap-fit ​​mechanism that can be detachably snapped into the hinge part 9.

[0038] The rotation axis of the adjusting arm 7 is perpendicular to both the scraping direction of the scraper 2 and the rotation axis of the positioning wheel 4.

[0039] In the above technical solution, when removing burrs at the corner of the injection molded part, the included angle between two adjacent surfaces of the injection molded part will be different. The common angle is 90 degrees, but when other angles occur, the snap-fit ​​mechanism can be driven to rotate the adjusting arm 7, thereby driving the ball 8 to rotate, which can adjust the angle of a pair of sliding auxiliary units to scrape off the burrs on the edge of different corners of the injection molded part. After the adjustment is completed, the adjusting arm 7 is fixed by the snap-fit ​​mechanism.

[0040] The end of the adjusting arm 7 uses a ball bearing 8 to slide in contact with the injection molded part. At different angles of the adjusting arm 7, different parts of the ball bearing 8 will contact the injection molded part, and the ball bearing 8 can rotate smoothly, improving applicability.

[0041] In a preferred embodiment of the present invention, the adjusting arm 7 is H-shaped, and a pair of balls 8 are assembled on the two ends of the adjusting arm 7 away from the mounting base 1. A mounting groove is provided through the center of the balls 8, and a first bolt 10 passing through the mounting groove is threadedly connected to the end of the adjusting arm 7.

[0042] In the above technical solution, the ball bearing 8 can be replaced by loosening and removing the first bolt 10, which is simple and convenient.

[0043] In a preferred embodiment of the present invention, there are two hinge parts 9. The two ends of the adjusting arm 7 near the mounting base 1 are respectively in contact with the outer wall opposite to the hinge part 9. The two ends of the adjusting arm 7 in contact with the hinge part 9 are equipped with hinge shafts 11 that pass through the two hinge parts 9.

[0044] The locking mechanism includes a sliding arm 12 that slides along the axis of the hinge shaft 11 with the adjusting arm 7, and the sliding arm 12 is detachably connected to one of the hinge parts 9.

[0045] In the above technical solution, when it is necessary to rotate the adjusting arm 7, the sliding arm 12 is pushed away from the corresponding hinge part 9 to rotate, so that the adjusting arm 7 can rotate freely around the hinge axis 11.

[0046] In a preferred embodiment of the present invention, the snap-fit ​​mechanism further includes a first snap-fit ​​sleeve 13 coaxially arranged with the hinge shaft 11 and sleeved on the outside of the hinge shaft 11 and fixedly connected to the corresponding hinge part 9, a second snap-fit ​​sleeve 14 slidably sleeved on the hinge shaft 11 and fixedly connected to the sliding arm 12, and a spring 15 sleeved on the hinge shaft 11 for pushing the second snap-fit ​​sleeve 14 closer to the first snap-fit ​​sleeve 13 to slide.

[0047] The first card sleeve 13 and the second card sleeve 14 are recessed at their respective ends and have a plurality of card slots evenly distributed along the circumferential direction. The second card sleeve 14 is provided with at least one card block portion that matches the card slot.

[0048] In the above technical solution, the sliding arm 12 is pushed to drive the second sleeve 14 to slide away from the first sleeve 13 on the hinge shaft 11, so that the second sleeve 14 is separated from the first sleeve 13 and the locking block moves out of the corresponding slot. At this time, the adjusting arm 7 can rotate around the hinge shaft 11. After the adjustment is completed, the sliding arm 12 is released, and the spring 15 will push the second sleeve 14 to slide closer to the first sleeve 13. The locking block will be inserted into the corresponding slot, thereby fixing the adjusting arm 7.

[0049] The more slots there are, the more angles that the adjusting arm 7 can adjust. At this time, the angle that the adjusting arm 7 can adjust is a fixed angle. Therefore, during adjustment, there will be a difference in the actual angle between the two adjacent surfaces of the injection molded part. That is, the scraper 2 will shake within a small range, but it will not affect the scraper 2's removal of burrs, because even if the blade part 5 is slightly deflected, it can still remove burrs.

[0050] In a preferred embodiment of the present invention, the mounting base 1 includes a pair of parallel mounting plates and a mounting arm whose two ends are respectively fixedly connected to the pair of mounting plates. The mounting arm is located between the positioning wheel 4 and the scraper 2.

[0051] The mounting plate has a recessed mounting groove 16 with an open top on the opposite side wall. The end of the scraper 2 is slidably inserted into the mounting groove 16. The mounting arm is equipped with a positioning plate 17 by several second bolts. The positioning plate 17 can press and hold the scraper 2 on the side away from the blade 5. The two sides of the positioning plate 17 are slidably inserted into the corresponding mounting groove 16.

[0052] In the above technical solution, when it is necessary to replace the scraper 2, loosen the second bolt to remove the positioning plate 17, remove both ends of the scraper 2 from the corresponding mounting slots 16, insert both ends of the new scraper 2 into the corresponding mounting slots 16 respectively, and then fix the scraper 2 by the positioning plate 17.

[0053] In a preferred embodiment of the present invention, the two ends of the spring 15 abut against the hinge portion 9 away from the first sleeve 13 and the second sleeve 14, respectively.

[0054] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0055] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0056] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
