Description

Technical Field

[0001] This application relates to the field of polishing technology, and in particular to a polishing tooling for the production and processing of injection molds for new energy vehicle parts. Background Technology

[0002] With the rapid development of the new energy vehicle industry, injection molds for new energy vehicle components are increasingly widely used in the production of various products. Their quality directly affects the performance, precision, and reliability of the final product. After the initial processing of mold components, surface defects may lead to problems such as accelerated wear and assembly difficulties during use, thereby affecting the service life of the mold and the molding quality of the product. Especially in the processing of guide sleeve mold parts, surface finish and assembly accuracy directly affect the stability and service life of the mold during high-speed, continuous injection molding. Any minor defects may lead to accelerated mold wear and increased assembly deviations, thus affecting the molding quality of the injection molded parts and the overall performance of the new energy vehicle components.

[0003] In existing technologies, manual or semi-automatic methods are commonly used to grind guide sleeves. The common practice is to first clamp the guide sleeve onto a fixed fixture, and then the operator manually grinds one end of the guide sleeve using a grinding tool; alternatively, a robotic arm can drive the grinding head to complete the grinding operation. After grinding one end, the operator must manually remove the guide sleeve from the fixture, flip it over, and re-clamp it before grinding the other end.

[0004] The existing technology has obvious shortcomings. The operation steps are cumbersome, and each flip of the guide sleeve relies on manual operation, which increases the complexity of the process and time costs, and reduces production efficiency. Summary of the Invention

[0005] In order to reduce the processing steps in the guide sleeve grinding process and improve grinding efficiency, this application provides a grinding fixture for the production and processing of injection molds for new energy vehicle parts.

[0006] A grinding fixture for manufacturing injection molds for new energy vehicle parts includes a base plate fixedly mounted on a workbench. Two side plates are symmetrically fixedly connected to the base plate. A movable plate is slidably connected to the two side plates. A flip plate is rotatably connected to the two movable plates. The rotation axis of the flip plate is perpendicular to the side plates and the movable plates. The flip plate is provided with a clamping mechanism for clamping and fixing guide sleeves. The base plate is provided with a grinding mechanism for grinding the guide sleeves. The flip plate is provided with a flipping mechanism for driving the flip plate to rotate 180° when the movable plate slides away from the grinding mechanism.

[0007] By adopting the above technical solution, a base plate is set on the workbench to stably support the entire fixture; the side plates on the base plate can be used to install a movable plate, allowing the movable plate to slide on the side plates. The rotating plate connected to the movable plate can rotate, and the clamping mechanism clamps and fixes the guide sleeve, facilitating the grinding mechanism on the base plate to grind the guide sleeve; the rotating mechanism can drive the rotating plate to rotate 180° when the movable plate slides away from the grinding mechanism. At this time, the clamping mechanism releases the clamping mechanism on the guide sleeve, and the guide sleeve can automatically rotate. Then, the rotated guide sleeve can be directly picked up and re-clamped to grind the other end of the guide sleeve, saving operation steps and improving grinding efficiency.

[0008] Preferably, the rotating shaft is fixedly disposed on both sides of the flipping plate, the rotating shaft is rotatably connected to the moving plate, the flipping mechanism includes a swing arm fixedly connected to the rotating shaft, the swing arm is located between the moving plate and the side plate, a guide wheel is rotatably connected to the swing arm, a cam groove is on the side plate, and the guide wheel is slidably disposed in the cam groove.

[0009] By adopting the above technical solution, the flip plate is rotatably connected to the moving plate through a rotating shaft. In conjunction with the flipping mechanism composed of a swing arm, guide wheel and cam groove, when the moving plate slides away from the grinding mechanism, the guide wheel slides in the cam groove and drives the swing arm to rotate. This causes the rotating shaft fixed to the swing arm to drive the flip plate to rotate 180°, thereby flipping the guide sleeve and facilitating the grinding operation on the other side of the guide sleeve.

[0010] Preferably, the clamping mechanism includes a clamping plate slidably disposed on a flip plate, the end of the clamping plate being provided with a V-shaped clamping groove, a sleeve being provided on the flip plate opposite the clamping plate, the sleeve being provided with a guide groove for the clamping plate to be inserted, the sleeve being provided with an opening groove corresponding to the clamping groove, and a driving member being provided on the flip plate for driving the clamping plate to slide toward the sleeve.

[0011] By adopting the above technical solution, a clamping mechanism is set on the flipping plate. The clamping plate is driven to slide towards the sleeve by the driving component. The clamping groove with a V-shape at the end of the clamping plate cooperates with the opening groove on the sleeve to stably and firmly clamp and fix the guide sleeve, providing a stable fixed foundation for subsequent grinding work.

[0012] Preferably, a support plate is fixedly connected to the bottom surface of the sleeve, the support plate is located below the opening groove, the sleeve is slidably disposed on the flip plate, the sliding direction of the sleeve is parallel to the sliding direction of the clamping plate, the flip plate is provided with a locking member for fixing the sleeve to the flip plate, and the bottom plate is provided with an unlocking member. When the moving plate slides to the end away from the grinding mechanism, the unlocking member releases the locking member from locking the sleeve.

[0013] By adopting the above technical solution, the support plate can support the guide sleeve, improving the fixing effect of the guide sleeve on the support plate. The locking component can fix the clamping sleeve on the flip plate without affecting the clamping of the guide sleeve. When the moving plate slides to the end away from the grinding mechanism, the unlocking component releases the locking component from locking the clamping sleeve. At this time, the clamping sleeve can be loosened directly, and the clamping plate can be released from clamping the guide sleeve. The guide sleeve can fall directly from between the clamping sleeve and the clamping plate, which is convenient for replacing the guide sleeve and improving processing efficiency.

[0014] Preferably, the locking component includes a locking hook rotatably disposed on the bottom surface of the flip plate. The locking hook is disposed on both sides of the support plate and can restrict the support plate from sliding outward toward the flip plate. The unlocking component includes a lever fixedly disposed on the side plate. When the flip plate slides to the end away from the grinding mechanism, the lever drives the locking hook to rotate to the outside of the support plate.

[0015] By adopting the above technical solution, the flipping mechanism, through the cooperation of the swing arm and guide wheel with the cam groove on the side plate, enables the flipping plate to rotate 180° when the moving plate moves away from the grinding mechanism. The clamping mechanism clamps the guide sleeve through the cooperation of the clamping plate and the clamping sleeve. On this basis, the locking hook is set on both sides of the support plate to restrict the outward sliding of the clamping sleeve, which can stably fix the clamping sleeve on the flipping plate. When the flipping plate slides to the end away from the grinding mechanism, the lever drives the locking hook to rotate to the outside of the support plate, which can automatically release the clamping sleeve lock, making it convenient to replace the guide sleeve or adjust the position.

[0016] Preferably, the flip plate is provided with a receiving groove for installing the clip, and the end of the clip is provided with a guide rod. The guide rod passes through the flip plate and is connected to a first spring. The first spring drives the clip to slide towards the outside of the receiving groove.

[0017] By adopting the above technical solution, a receiving groove is set on the flip plate for installing the clamp. A guide rod is provided at the end of the clamp and connected to a first spring. The first spring drives the clamp to slide out of the receiving groove, so that the clamp can automatically slide out of the receiving groove when it is not restricted by other external forces, making it easy for the guide sleeve to fall from between the clamp and the clamp plate.

[0018] Preferably, a push rod is provided on the bottom plate near the grinding mechanism. The push rod is positioned towards the clamping sleeve. When the flip plate slides to the end near the grinding mechanism, the push rod pushes the clamping sleeve into the receiving groove.

[0019] By adopting the above technical solution, when the flip plate slides to one end close to the grinding mechanism, the push rod can push the sleeve into the receiving groove to realize the reset of the sleeve. After the sleeve is reset, the guide sleeve can be clamped again, which improves the automation level and work efficiency of the grinding fixture.

[0020] Preferably, the polishing mechanism includes a polishing frame that slides vertically on a base plate, a polishing motor that is fixedly connected to the polishing frame, and a polishing disc that is connected to the polishing motor for polishing the guide sleeve.

[0021] By adopting the above technical solution, the grinding frame can slide vertically on the base plate, the height of the grinding disc can be adjusted, and the grinding motor drives the grinding disc to rotate, thereby achieving the grinding of the guide sleeve.

[0022] Preferably, a sleeve is fixedly connected to the base plate, the grinding frame is slidably disposed inside the sleeve, a drive gear is rotatably connected inside the sleeve, and a first rack that meshes with the drive gear is provided on the grinding frame.

[0023] By adopting the above technical solution, a sleeve is fixed on the base plate, allowing the grinding frame to slide inside the sleeve. The rotating drive gear inside the sleeve meshes with the first rack on the grinding frame, enabling the grinding frame to slide stably in the vertical direction. This, in turn, drives the grinding motor and grinding disc to move up and down, facilitating grinding operations at different positions on the guide sleeve and improving grinding accuracy and flexibility.

[0024] Preferably, a second rack is slidably connected to the sleeve relative to the first rack, the second rack meshes with the drive gear, a positioning plate is fixedly connected to the second rack, the positioning plate is located below the flip plate, a plurality of positioning posts are fixedly connected to the positioning plate, and positioning holes are provided on the flip plate corresponding to the positioning posts.

[0025] By adopting the above technical solution, the meshing transmission between the first rack and the drive gear drives the second rack, which meshes with the drive gear, to move. This causes the positioning plate fixed on the second rack to move, and the positioning pin on the positioning plate inserts into the positioning hole on the flip plate, thereby positioning the flip plate and improving the stability of the guide sleeve and the grinding accuracy during grinding.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By setting a flip-up plate and a corresponding flip-up mechanism, the guide sleeve can be automatically flipped, which facilitates comprehensive and uniform grinding of all surfaces of the guide sleeve, reduces operation steps, and improves grinding efficiency.

[0028] 2. The clamping mechanism, consisting of a clamping plate and a clamping sleeve with a V-shaped clamping groove, can more stably clamp and fix the guide sleeve, ensuring the accurate position of the guide sleeve during the grinding process, improving grinding precision and consistency, and can adapt to grinding guide sleeves of different diameters, making it highly adaptable.

[0029] 3. The grinding frame of the grinding mechanism can slide vertically, and the grinding position can be flexibly adjusted according to actual needs, so as to better adapt to the grinding of guide sleeves of different sizes and shapes, and improve the versatility and applicability of the tooling.

[0037] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0038] This application discloses a grinding fixture for the production and processing of injection molds for new energy vehicle parts. (Refer to...) Figure 1The grinding fixture for mold production and processing includes a base plate 1 fixedly mounted on a workbench. The base plate 1 is horizontally fixed on the workbench by a pressure plate. Two side plates 2 are symmetrically arranged on the base plate 1. The side plates 2 are vertically arranged and their bottoms are fixedly connected to the base plate 1. A movable plate 3 is slidably connected to the two side plates 2. The movable plate 3 is located between the two side plates 2. A guide rail 22 is fixedly connected to the side plates 2. The guide rail 22 is horizontally arranged. A slider is provided on the movable plate 3 and is slidably connected to the guide rail 22. The sliding connection between the movable plate 3 and the side plates 2 is realized through the cooperation of the slider and the guide rail 22. A flip plate 4 is provided between the two movable plates 3. The flip plate 4 is rotatably connected to the movable plate 3 and the axis of rotation is perpendicular to the movable plate 3. A clamping mechanism 5 for clamping and fixing the guide sleeve is provided on the flip plate 4. A grinding mechanism 7 for grinding the guide sleeve is provided on the base plate 1.

[0039] During operation, the guide sleeve is fixed on the flip plate 4 by the clamping mechanism 5. Then, the sliding plate 3 is moved to the grinding mechanism 7. The grinding mechanism 7 grinds the end of the guide sleeve. After grinding is completed, the flip plate 4 is reset, the clamping mechanism 5 is released, and the guide sleeve can be removed from the flip plate 4.

[0040] To facilitate the flipping operation of the guide sleeve, a flipping mechanism 6 is provided on the flipping plate 4. The flipping mechanism 6 is used to drive the flipping plate 4 to rotate 180° when the moving plate 3 slides away from the grinding mechanism 7. With the flipping mechanism 6, the flipping plate 4 automatically flips when the moving plate 3 is reset, simplifying the operation steps and improving the operation efficiency.

[0041] Reference Figure 2 The flipping mechanism 6 includes a swing arm 61 and a guide wheel 62. A rotating shaft 45 is fixedly connected to both sides of the flipping plate 4. The end of the rotating shaft 45 passes through the moving plate 3 and is fixed to the swing arm 61. The swing arm 61 is located between the moving plate 3 and the side plate 2. The guide wheel 62 is rotatably disposed at the end of the swing arm 61 away from the rotating shaft 45. A cam groove 21 is provided on the side plate 2 along the length direction of the side plate 2. The cam groove 21 is arched in the middle. The guide wheel 62 is slidably disposed in the cam groove 21. When the guide wheel 62 moves to the highest point in the cam groove 21, the swing arm 61 is vertically disposed. Through the cooperation of the guide wheel 62 and the cam groove 21, the swing arm 61 is driven to rotate, thereby realizing the rotation of the flipping plate 4.

[0042] Reference Figure 3The grinding mechanism 7 includes a grinding frame 72 that slides vertically on a base plate 1. A sleeve 71 is fixedly connected to the base plate 1, and the sleeve 71 is vertically positioned. The bottom of the grinding frame 72 is slidably connected to the sleeve 71. A grinding motor 721 is fixedly connected to the top of the grinding frame 72. The output shaft of the grinding motor 721 is vertically positioned, and a grinding disc 722 for grinding the guide sleeve is connected to the output shaft of the grinding motor 721. During the grinding operation, the grinding frame 72 slides downward, the grinding disc 722 contacts the guide sleeve, and the grinding motor 721 drives the grinding disc 722 to rotate around the guide sleeve, thereby realizing the grinding operation of the guide sleeve.

[0043] To facilitate the vertical sliding of the grinding frame 72, a drive gear 74 is rotatably connected inside the sleeve 71. The grinding frame 72 has a first rack 73 that meshes with the drive gear 74. The first rack 73 is vertically positioned and fixedly connected to the grinding frame 72. A second spring 75, vertically positioned, drives the grinding frame 72 to slide upwards, is located inside the sleeve 71. One end of the second spring 75 abuts against the bottom surface of the sleeve 71, and the other end abuts against the grinding frame 72. An operating lever 741 is fixedly connected to the rotating shaft of the drive gear 74, and the lever extends to the front end of the side plate 2. During operation, simply lifting the operating lever 741 drives the drive gear 74 to rotate, thereby causing the grinding frame 72 to slide downwards against the elastic force of the second spring 75. This drives the grinding motor 721 to approach the guide sleeve and grind the outer circumference of the guide sleeve.

[0044] To improve stability during the guide sleeve grinding process, a second rack 82 is slidably connected to the sleeve 71 relative to the first rack 73. The second rack 82 is vertically arranged and meshes with the drive gear 74. A positioning plate 8 is fixedly connected to the second rack 82. The positioning plate 8 is horizontally arranged and located below the flip plate 4. Several positioning pins 81 are fixedly connected to the positioning plate 8. The positioning pins 81 are vertically arranged, and their bottoms are fixedly connected to the positioning plate 8. The flip plate 4 has positioning holes 42 corresponding to the positioning pins 81. The inner diameter of the positioning holes 42 matches the outer diameter of the positioning pins 81. In this embodiment, there are four positioning pins 81 and four positioning holes 42. The four positioning holes 42 are located at the four corners of the flip plate 4. The bottom of the positioning holes 42 is flared, and the inclined surface at the bottom of the positioning holes 42 can serve as a guide to facilitate the insertion of the positioning pins 81 into the positioning holes 42.

[0045] During grinding, the grinding frame 72 slides downward and the positioning plate 8 slides upward. The positioning pin 81 is first inserted into the positioning hole 42. At this time, the guide sleeve is located directly below the grinding motor 721. During the grinding process, the positioning pin 81 is always located in the positioning hole 42. At this time, the flip plate 4 cannot slide, and the guide sleeve is positioned below the grinding motor 721, which effectively improves the grinding accuracy of the guide sleeve.

[0046] Reference Figure 4 as well as Figure 5 The clamping mechanism 5 includes a clamping plate 51 and a clamping sleeve 52. The clamping plate 51 is horizontally arranged and slides along the length of the side plate 2 on the flip plate 4. The clamping sleeve 52 is arranged on the flip plate 4 relative to the clamping plate 51. Both the flip plate 4 and the clamping sleeve 52 are provided with sliding grooves for the clamping plate 51 to slide. The clamping plate 51 is provided with a clamping groove 511 at its end. The clamping groove 511 is V-shaped. The clamping sleeve 52 is provided with an opening groove 521 facing the clamping groove 511. The opening groove 521 is also V-shaped. During normal clamping, the clamping sleeve 52 is fixed on the flip plate 4. The guide sleeve is vertically clamped and fixed on the flip plate 4 by sliding the clamping plate 51 toward the clamping sleeve 52.

[0047] To facilitate the sliding of the clamping plate 51, a driving component is provided on the flip plate 4 to drive the clamping plate 51 to slide toward the clamping sleeve 52. The driving component includes a screw 53 rotatably disposed on the flip plate 4. The screw 53 is threadedly connected to the flip plate 4. The screw 53 is disposed along the length direction of the side plate 2. The end of the screw 53 is rotatably connected to the clamping plate 51. By rotating the screw 53, the clamping plate 51 can be driven to slide toward or away from the clamping sleeve 52, thereby achieving the clamping and fixing of the guide sleeve.

[0048] To improve the fixing effect of the guide sleeve on the flip plate 4, a support plate 54 is fixedly connected to the bottom surface of the sleeve 52. The support plate 54 is located below the opening slot 521. The support plate 54 can support the sleeve 52 and improve the stability of the sleeve 52 during the grinding process. To facilitate the detachment of the guide sleeve from the flip plate 4, the clamp 52 is slidably mounted on the flip plate 4. The flip plate 4 has a receiving groove 41 that mates with the clamp 52. The clamp 52 is slidably mounted in the receiving groove 41 and slides along the length of the side plate 2. The end of the clamp 52 is fixedly connected to a guide rod 522. There are two guide rods 522, located on both sides of the clamp 51 respectively. The guide rods 522 are slidably connected to the flip plate 4. The end of the guide rod 522 extends out of the flip plate 4 and is connected to the first spring 523. The first spring 523 is sleeved on the guide rod 522. One end of the first spring 523 abuts against the flip plate 4, and the other end is connected to the guide rod 522. The first spring 523 drives the clamp 52 to slide outward from the flip plate 4.

[0049] Reference Figure 5 as well as Figure 6 The flip plate 4 is provided with a locking member for fixing the clamp 52 to the flip plate 4, and the base plate 1 is provided with an unlocking member. When the moving plate 3 slides to the end away from the grinding mechanism 7, the unlocking member releases the locking member from locking the clamp 52. At this time, the clamp 52 slides outward from the flip plate 4 under the drive of the first spring 523, and the guide sleeve automatically falls off between the clamp 52 and the clamping plate 51 and falls onto the base plate 1, further reducing the operation steps and improving the processing efficiency.

[0050] The locking mechanism includes two locking hooks 43 rotatably mounted on the bottom surface of the flip plate 4, symmetrically arranged on both sides of the support plate 54. After rotation, the locking hooks 43 abut against the end of the support plate 54, restricting the support plate 54 from sliding outwards from the flip plate 4. Since the support plate 54 is fixedly connected to the sleeve 52, it also limits the position of the sleeve 52, fixing it within the receiving groove 41. The unlocking mechanism includes a lever 23 fixedly mounted on the side plate 2. The lever 23 is perpendicular to the side plate 2 and is located at the end of the side plate 2 away from the grinding mechanism 7. The end of the locking hook 43 away from the hook body bends outwards, facilitating contact between the locking hook 43 and the lever 23. When the flip plate 4 slides to the end away from the grinding mechanism 7, the lever 23 abuts against the protruding end of the locking hook 43, driving the locking hook 43 to rotate away from the support plate 54, thereby releasing the locking hook 43 from limiting the support plate 54. To facilitate the reset of the locking hook 43, a torsion spring 44 is sleeved on the rotating shaft of the locking hook 43. One end of the torsion spring 44 is connected to the flip plate 4, and the other end is connected to the locking hook 43. The torsion spring 44 drives the locking hook 43 to rotate towards the support plate 54.

[0051] To facilitate the reset of the sleeve 52, a push rod 9 is provided on the sleeve 71. The push rod 9 is positioned towards the sleeve 52. When the flip plate 4 slides to one end close to the grinding mechanism 7, the push rod 9 pushes the sleeve 52 into the receiving groove 41. At this time, the locking hook 43, driven by the torsion spring 44, hooks the support plate 54, and the sleeve 52 can be fixed in the receiving groove 41. To prevent the grinding motor 721 from sliding downwards during clamping, which could pose a safety hazard to the operator, the positioning rod and positioning hole 42 are misaligned when the clamping sleeve 52 abuts against the push rod 9. The positioning rod cannot slide upwards, thus restricting the downward sliding of the grinding frame 72 and limiting the grinding motor 721. Furthermore, the push rod 9 is threadedly connected to the sleeve 71, facilitating the adjustment of the extension of the push rod 9 and thereby adjusting the position of the flip plate 4. After clamping, since the bottom of the positioning hole 42 is set in an unfolded position, it is only necessary to pull the flip plate 4 back a suitable distance to roughly align the positioning hole 42 with the positioning rod, and then lift the operating rod 741 upwards to drive the grinding camera to slide downwards and grind the guide sleeve.

[0052] Finally, to facilitate the sliding of the movable plate 3, a handle 31 is fixedly connected between the two movable plates 3, and the two ends of the handle 31 are fixedly connected to the corresponding movable plate 3 respectively.

[0053] The implementation principle of this application embodiment is as follows: By placing the guide sleeve in the clamping mechanism 5, rotating the screw 53, the screw 53 drives the clamping plate 51 to slide, so that the clamping plate 51 and the clamping sleeve 52 cooperate to firmly clamp the guide sleeve, pushing the moving plate 3 to slide on the side plate 2, driving the guide sleeve closer to the grinding mechanism 7, the grinding motor 721 rotates, and the grinding frame 72 slides vertically on the base plate 1, so that the grinding disc 722 grinds the guide sleeve. When it is necessary to grind the other side of the guide sleeve, the moving plate 3 slides away from the grinding mechanism 7. At this time, the guide wheel 62 slides in the cam groove 21, driving the swing arm 61 to rotate, thereby causing the flipping plate 4 to rotate 180°, realizing the flipping of the guide sleeve, so that the other side of the guide sleeve can be ground. This design avoids the cumbersome operation of repeatedly disassembling and re-fixing the guide sleeve in the traditional grinding method, improves grinding efficiency and accuracy, and also ensures the stability of grinding quality, which has significant improvement and contribution to the prior art.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
