Description

Technical Field

[0001] This invention relates to the field of internal cone grinding equipment technology, and in particular to a method and apparatus for mirror grinding of mold surfaces. Background Technology

[0002] Internal cone grinding equipment is a device used for grinding internal cone surfaces. The part to be processed is placed on a worktable, and then the grinding head drive is activated to rotate the grinding head and grind the internal cone surface. During the grinding process, the control system can adjust parameters such as the grinding head rotation speed, grinding pressure, and grinding time as needed to ensure grinding quality and efficiency. After grinding is completed, the grinding head drive is turned off, and the processed part is removed. Internal cone grinding equipment is widely used in machinery manufacturing, automobile manufacturing, aerospace, and other fields, and is an important internal cone surface processing device. Therefore, a high-precision mold internal cone surface grinding device is particularly needed.

[0003] A search revealed Chinese invention patent CN118682582A, which discloses a high-precision grinding device for the inner cone surface of a mold. The device includes a fixed plate with a clamping mechanism at one end. During use, when grinding the surface of the inner cone, the cone itself possesses magnetic properties, causing it to become magnetically connected to a magnet. As the cone grinds the inner cone surface, a first drive motor is controlled to move the mold away from the cone, and a third drive motor is activated to move the magnet away from the fitting groove. At this point, the cone loses its magnetism, and the iron filings on the cone fall onto the chip collection platform. This structure effectively reduces the impact of iron filings on the surface accuracy and roughness of the inner cone during grinding, ensuring extremely high dimensional accuracy, shape accuracy, and surface roughness, thus greatly improving the quality and yield of mold forming.

[0004] Traditional rigid clamping requires manual adjustment of the spacing, which is time-consuming and can easily cause mold deformation or surface damage due to uneven clamping force. Molds of different sizes require frequent clamping changes, resulting in poor versatility. Angle adjustment relies on manual disassembly and reassembly, which is inefficient. After adjustment, there is a lack of effective limit, and grinding vibration can easily cause angle deviation, affecting the machining accuracy of curved surfaces.

[0005] Therefore, the existing method and apparatus for mirror polishing of mold surfaces cannot meet the needs of actual use, so there is an urgent need for improved technology in the market to solve the above problems. Summary of the Invention

[0013] Preferably, the sliding structure includes a second slider that is slidably connected to the upper end face of the placement frame, a second sliding plate that is fixedly connected to the upper end of the second slider, an adjusting plate that is fixedly connected to the middle of the lower end face of the second sliding plate, and a threaded rod that passes through the adjusting plate and is threadedly connected.

[0014] Preferably, the grinding structure includes a grinding frame fixedly connected to the middle of the upper end face of the sliding plate two, a ball bearing is evenly slidably connected to the inner cavity of the grinding frame near the clamping structure, a grinding shaft is slidably connected to the inner cavity of the grinding frame, the ball bearing is movably connected to the middle of the outer surface of the grinding shaft, and a grinding component is provided in the inner cavity of the grinding shaft. The grinding assembly includes a starch threaded mounting groove on the side of the grinding shaft near the clamping structure. A limit bolt is uniformly threaded on the outer surface of the grinding shaft within the inner cavity of the threaded mounting groove. A grinding head is threadedly connected within the inner cavity of the threaded mounting groove. The limit bolt passes through the grinding shaft and is threadedly connected to the grinding head.

[0015] Preferably, the grinding drive structure includes a grinding motor fixedly connected to the upper end face of the sliding plate two, located on the side of the grinding frame away from the grinding shaft. The output end of the grinding motor passes through the grinding frame, and a driving bevel gear is fixedly connected to the output end of the grinding motor. A transmission bevel gear one is fixedly connected to the middle of the lower end face of the inner cavity of the grinding frame. The driving bevel gear and the transmission bevel gear one mesh with each other. A transmission bevel gear two is fixedly connected to the side of the grinding shaft away from the clamping structure.

[0016] A method for mirror polishing of mold surface, characterized by comprising the following steps: S1: Push the clamping frame 41 towards each other, so that the clamping frame 41 and the slider 32 move relative to each other, so that the spring on the outer surface of the sliding rod 31 is stretched, and the clamping structures 4 on both sides move away from each other; S2: At this time, the operator places the mold between the two positioning rollers 44. At this time, the clamping frame 41 is released, so the spring on the outer surface of the sliding rod 31 contracts, which causes the two sliders 32 to move closer to each other, and further causes the clamping structure 4 to move closer to each other. Therefore, the mold is positioned and clamped by the positioning rollers 44 and the rotating frame 43. S3: When adjusting the grinding angle of the mold, the mold is pushed laterally, causing the positioning roller 44, the rotating frame 43 and the rotating plate 42 to rotate laterally. At the same time, when the mold rotates laterally, the limiting gear 111 rotates, so the limiting pin 114 retracts into the inner cavity of the limiting frame 112, which in turn causes the limiting spring 113 to retract. When the mold rotation is complete, the limiting spring 113 extends, so the limiting pin 114 slides upward, which causes the limiting pin 114 to engage with the tooth groove on the outer surface of the limiting gear 111, thus limiting and fixing the rotating clamping structure 4. S4: When the mold is adjusted longitudinally, the mold is pushed longitudinally. Since the mold is placed between the two clamping structures 4 through the positioning roller 44 and the rotating frame 43, the mold rotates longitudinally when the mold is pushed longitudinally, which in turn causes the positioning roller 44 to rotate. Since the adjacent side of the two rotating frames 43 is an arc structure, the mold can still be stably placed between the two clamping structures 4 when the mold rotates longitudinally. S5: During mirror polishing, the lifting structure 5 is activated, which activates the control module 52. At this time, the control signal and current are transmitted to the electric telescopic rod 51 through the connecting cable 53. Therefore, the electric telescopic rod 51 extends and retracts, realizing the lifting and lowering of the placement structure 6. When the polishing structure 9 and the mold polishing area are at the same horizontal height, the drive structure 7 is activated, which makes the output end of the micro motor 74 rotate. Therefore, the drive gear 73 rotates. Since the drive gear 73 meshes in the inner cavity of the toothed belt 72, the toothed belt 72 rotates, which further makes the transmission gear 71 rotate. Therefore, the threaded rod 63 rotates. Therefore, the sliding plate 82 is pushed by the adjusting plate 83, which makes the slider 81 slide along the placement frame 62 towards the mold side. S6: Further activate the grinding drive structure 10, causing the output end of the grinding motor 101 to rotate, thus driving the bevel gear 102 to rotate. Since the transmission bevel gear 103 meshes with the driving bevel gear 102, the transmission bevel gear 103 rotates, further causing the transmission bevel gear 104, which meshes with the transmission bevel gear 103, to rotate. Since the transmission bevel gear 104 is fixedly connected to the grinding shaft 93, the grinding shaft 93 rotates. At this time, since the grinding head 943 is located in the inner cavity of the grinding shaft 93, the surface of the mold is ground. When the grinding head 943 needs to be replaced, move the sliding structure 8 to the left, so that the grinding structure 9 is away from the mold. At this time, rotate the limiting bolt 942 in sequence, so that the limiting bolt 942 and the grinding head 943 are separated, thereby realizing the replacement of the grinding head 943.

[0017] The present invention has the following beneficial effects: This invention achieves elastic automatic clamping of the mold through the cooperation of a sliding rod, spring, and clamping frame. The mold can be put in and taken out simply by pushing the clamping frame. The clamping operation is simple and quick, greatly reducing labor intensity and improving processing efficiency, and is suitable for batch production needs. At the same time, the positioning roller makes rolling contact with the mold, avoiding scratches and indentations on the mold surface caused by rigid extrusion. The symmetrical and synchronous operation of the double-sided clamping structure ensures that the mold is evenly stressed and centrally positioned, with strong clamping stability, laying the foundation for subsequent high-precision grinding.

[0018] This invention supports dual-degree-of-freedom adjustment of the mold, allowing for both lateral rotation and longitudinal flipping. During lateral rotation, the combination of limiting gears, limiting pins, and limiting springs ensures automatic retraction and self-locking upon reaching the correct position, guaranteeing a stable grinding angle with high repeatability. During longitudinal flipping, the arc-shaped structure of the rotating frame ensures stable support of the mold during rotation, preventing it from slipping or wobbling. This dual-degree-of-freedom adjustment design eliminates the need for re-clamping, adapting to the grinding needs of various molds, including flat, inclined, curved, and irregular surfaces, significantly improving the device's versatility and applicability. The grinding transmission is smooth and the processing accuracy is high. The lifting structure achieves stepless and precise adjustment of the grinding height via an electric telescopic rod and control module, quickly aligning the mold grinding surface and avoiding manual adjustment errors. The drive structure uses a gear-toothed belt-threaded rod transmission method, resulting in small transmission gaps and smooth movement, enabling micro-feeding and meeting the low-pressure, high-precision feed requirements of mirror grinding, effectively preventing overcutting and vibration marks. The guide cooperation between the slider and the placement frame ensures the straightness of the grinding head's trajectory, resulting in uniform contact between the grinding head and the mold surface. Meanwhile, the grinding drive structure, driven by a bevel gear set, ensures stable power transmission and low noise, driving the grinding shaft and grinding head to rotate at a uniform speed. This guarantees low surface roughness and high gloss on the mold surface, achieving a mirror-like finish. The grinding head of this invention is fixed by a limiting bolt. When replacing it, simply move the sliding structure away from the mold and loosen the limiting bolt to complete the disassembly and installation of the grinding head. The replacement process is simple and time-saving, and can be quickly switched according to different process requirements such as rough grinding, fine grinding, and mirror grinding. The overall structure has reliable transmission and low failure rate, and each operation does not require complex professional skills, which reduces the skill requirements of the operators and facilitates long-term continuous production.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] According to claim 1, a mold surface mirror polishing device is characterized in that the adjusting structure 3 includes a sliding rod 31 symmetrically fixedly connected to the inner cavity of the mounting groove 22, a slider 32 symmetrically slidably connected to the outer surface of the sliding rod 31, a spring movably sleeved in the middle of the outer surface of the sliding rod 31, the spring being driven between the two sliders 32, an adjusting plate 33 fixedly connected to the upper end face of the slider 32, and a clamping structure 4 fixedly connected to the upper end face of the adjusting plate 33. Through the adjusting structure 3 on the mounting structure 2, the clamping structure 4 is installed and placed during use, and the distance between the clamping structures 4 is adjusted and controlled by the extension and retraction of the spring on the outer surface of the sliding rod 31 and the relative sliding of the sliders 32.

The adjacent arc structure of the rotating frame 43 provides continuous support for the mold, ensuring that the mold is always stable between the clamping structures 4 during longitudinal rotation.

[0027] According to claim 1, a mold surface mirror grinding processing device is characterized in that the lifting structure 5 includes electric telescopic rods 51 fixedly connected to the four corners of the lower end face of the inner cavity of the second mounting groove 23, a control module 52 fixedly connected to the middle of the lower end of the inner cavity of the second mounting groove 23, a connecting cable 53 connecting the electric telescopic rods 51 and the control module 52, and a placement structure 6 fixedly connected to the upper end face of the electric telescopic rods 51. Through the lifting structure 5 on the mounting structure 2, the placement structure 6 is installed and placed during use. Then, through the electric telescopic rods 51 and the control module 52, the height of the grinding head and the mold is automatically matched, eliminating the need for repeated manual adjustments, improving calibration efficiency and accuracy, and ensuring precise and controllable feeding process. The transmission structure of the threaded rod 63 ensures uniform and stable feeding speed, avoiding uneven grinding pressure caused by sudden changes in feeding speed, ensuring the consistency of grinding quality of the mold surface, reducing surface defects, and improving the automation level of the entire process.

Furthermore, through modular design, the polishing head 943 can be replaced without disassembling the entire device. It can be quickly completed through the sliding structure 8 and the limiting bolt 942, which is suitable for the rapid changeover requirements of multi-variety and small-batch molds. At this time, the modular components reduce the difficulty of maintenance and reduce downtime maintenance time. At the same time, the bevel gear transmission replaces the hydraulic / pneumatic system, reducing energy consumption and subsequent maintenance costs, and improving production economic efficiency.

[0031] According to claim 1, a mirror polishing device for mold surface is characterized in that the polishing structure 9 includes a polishing frame 91 fixedly connected to the middle of the upper end face of the sliding plate 82, a ball bearing 92 is evenly slidably connected to the inner cavity of the polishing frame 91 near the clamping structure 4, a polishing shaft 93 is slidably connected to the inner cavity of the polishing frame 91, the ball bearing 92 is movably connected to the middle of the outer surface of the polishing shaft 93, and a polishing assembly 94 is provided in the inner cavity of the polishing shaft 93.

A limit bolt 942 is uniformly threadedly connected to the outer surface of the grinding shaft 93 within the inner cavity of the threaded mounting groove 941. A grinding head 943 is threadedly connected to the inner cavity of the threaded mounting groove 941. The limit bolt 942 passes through the grinding shaft 93 and is threadedly connected to the grinding head 943.

[0032] According to claim 1, a mirror polishing device for mold surfaces is characterized in that the polishing drive structure 10 includes a polishing motor 101 fixedly connected to the upper end face of the sliding plate 2 82 on the side of the polishing frame 91 away from the polishing shaft 93. The output end of the polishing motor 101 passes through the polishing frame 91, and a drive bevel gear 102 is fixedly connected to the output end of the polishing motor 101.

[0033] According to claim 1, a method for mirror polishing of mold surface is characterized in that the limiting structure 11 includes a limiting gear 111 rotatably connected to the upper rear end of the clamping frame 41, a limiting frame 112 fixedly connected to the lower part of the limiting gear 111 at the rear end of the clamping frame 41, a limiting spring 113 fixedly connected to the lower end face of the inner cavity of the limiting frame 112, a limiting pin 114 fixedly connected to the upper end face of the limiting spring 113, the limiting pin 114 slidably connected to the inner cavity of the limiting frame 112, the upper end of the limiting pin 114 matching the tooth groove of the limiting gear 111, and the rear end shaft of the front rotating plate 42 passing through the clamping frame 41 and fixedly connected to the limiting gear 111. Through the limiting structure 11 on the clamping structure 4, the composite angle adjustment of the horizontal and vertical directions is supported during use to meet the grinding angle requirements of complex curved surface molds; the meshing and locking mechanism of the limiting gear 111 and the limiting pin 114 realizes precise angle positioning, avoids angle deviation caused by vibration during the grinding process, and ensures grinding accuracy.

[0034] Working principle: During operation, the clamping frame 41 is pushed towards each other, causing the clamping frame 41 and the slider 32 to move relative to each other. As a result, the spring on the outer surface of the sliding rod 31 is stretched, and the clamping structures 4 on both sides move away from each other. At this time, the operator places the mold between the two positioning rollers 44. At this time, the clamping frame 41 is released, so the spring on the outer surface of the sliding rod 31 contracts, which causes the two sliders 32 to move closer to each other, and further causes the clamping structure 4 to move closer to each other. Therefore, the mold is positioned and clamped by the positioning rollers 44 and the rotating frame 43. When adjusting the grinding angle of the mold, the mold is pushed laterally, causing the positioning roller 44, the rotating frame 43, and the rotating plate 42 to rotate laterally. At the same time, when the mold rotates laterally, the limiting gear 111 rotates, so the limiting pin 114 retracts into the inner cavity of the limiting frame 112, which in turn causes the limiting spring 113 to retract. When the mold rotation is complete, the limiting spring 113 extends, so the limiting pin 114 slides upward, which causes the limiting pin 114 to engage with the tooth groove on the outer surface of the limiting gear 111, thus limiting and fixing the rotating clamping structure 4. Furthermore, when the mold is adjusted longitudinally, the mold is pushed longitudinally. Since the mold is placed between the two clamping structures 4 via the positioning roller 44 and the rotating frame 43, the mold rotates longitudinally when the mold is pushed longitudinally, which in turn causes the positioning roller 44 to rotate. Since the adjacent side of the two rotating frames 43 is an arc-shaped structure, the mold can still be stably placed between the two clamping structures 4 when the mold rotates longitudinally. During mirror polishing, the lifting structure 5 is activated, which activates the control module 52. At this time, the control signal and current are transmitted to the electric telescopic rod 51 through the connecting cable 53. Therefore, the electric telescopic rod 51 extends and retracts, realizing the lifting and lowering of the placement structure 6. When the polishing structure 9 and the polishing part of the mold are at the same horizontal height, the drive structure 7 is activated, which makes the output end of the micro motor 74 rotate. Therefore, the drive gear 73 rotates. Since the drive gear 73 meshes in the inner cavity of the toothed belt 72, the toothed belt 72 rotates, which further makes the transmission gear 71 rotate. Therefore, the threaded rod 63 rotates. Thus, the sliding plate 82 is pushed by the adjusting plate 83, which makes the slider 81 slide along the placement frame 62 towards the mold side. The grinding drive structure 10 is further activated, causing the output end of the grinding motor 101 to rotate, thus driving the bevel gear 102 to rotate. Since the transmission bevel gear 103 meshes with the drive bevel gear 102, the transmission bevel gear 103 rotates, further causing the transmission bevel gear 104, which meshes with the transmission bevel gear 103, to rotate. Since the transmission bevel gear 104 is fixedly connected to the grinding shaft 93, the grinding shaft 93 rotates. At this time, since the grinding head 943 is located in the inner cavity of the grinding shaft 93, the surface of the mold is ground. When the grinding head 943 needs to be replaced, the sliding structure 8 is moved to the left, causing the grinding structure 9 to move away from the mold. At this time, the limiting bolt 942 is rotated in sequence, causing the limiting bolt 942 to separate from the grinding head 943, thereby realizing the replacement of the grinding head 943.

The rear end shaft of the front rotating plate (42) passes through the clamping frame (41) and is fixedly connected to the limiting gear (111).

10. A method for mirror polishing of a mold surface according to claim 1, characterized in that, Includes the following steps S1: Push the clamping frame (41) towards each other, so that the clamping frame (41) and the slider (32) move relative to each other, so that the spring on the outer surface of the sliding rod (31) is stretched, and the clamping structures (4) on both sides move away from each other; S2: At this time, the personnel place the mold between the two positioning rollers (44), and then release the clamping frame (41). As a result, the spring on the outer surface of the sliding rod (31) contracts, which causes the two sliders (32) to move closer to each other, and further causes the clamping structure (4) to move closer to each other. Therefore, the mold is positioned and clamped by the positioning rollers (44) and the rotating frame (43). S3: When adjusting the grinding angle of the mold, the mold is pushed laterally, so that the positioning roller (44), the rotating frame (43) and the rotating plate (42) can be rotated laterally. At the same time, when the mold rotates laterally, the limiting gear (111) rotates, so the limiting pin (114) retracts into the inner cavity of the limiting frame (112), which in turn causes the limiting spring (113) to retract. When the mold rotation is completed, the limiting spring (113) extends, so the limiting pin (114) slides upward, which causes the limiting pin (114) to engage with the tooth groove on the outer surface of the limiting gear (111), thus limiting and fixing the clamping structure (4) after rotation. S4: When the mold is adjusted longitudinally, the mold is pushed longitudinally. Since the mold is placed between the two clamping structures (4) through the positioning roller (44) and the rotating frame (43), the mold rotates longitudinally when the mold is pushed longitudinally, which causes the positioning roller (44) to rotate. Since the adjacent side of the two rotating frames (43) is an arc structure, the mold can still be stably placed between the two clamping structures (4) when the mold rotates longitudinally. S5: When performing mirror grinding, the lifting structure (5) is activated, which enables the control module (52) to start. At this time, the control signal and current are transmitted to the electric telescopic rod (51) through the connecting cable (53). Therefore, the electric telescopic rod (51) extends and retracts, realizing the lifting of the placement structure (6). When the grinding structure (9) and the grinding part of the mold are at the same horizontal height, the drive structure (7) is activated, which causes the output end of the micro motor (74) to rotate. Therefore, the drive gear (73) rotates. Since the drive gear (73) meshes in the inner cavity of the toothed belt (72), the toothed belt (72) rotates, which further causes the transmission gear (71) to rotate. Therefore, the threaded rod (63) rotates. Therefore, the sliding plate (82) is pushed by the adjustment plate (83), causing the slider (81) to slide along the placement frame (62) towards the mold side. S6: Further activate the grinding drive structure (10) to make the output end of the grinding motor (101) rotate, so the drive bevel gear (102) rotates. Since the first transmission bevel gear (103) meshes with the drive bevel gear (102), the first transmission bevel gear (103) rotates. Further, the second transmission bevel gear (104) meshes with the first transmission bevel gear (103) rotates. Since the second transmission bevel gear (104) is fixedly connected to the grinding shaft (93), the grinding shaft (93) rotates. At this time, since the grinding head (943) is located in the inner cavity of the grinding shaft (93), the surface of the mold is ground. When the grinding head (943) needs to be replaced, move the sliding structure (8) to the left so that the grinding structure (9) is far away from the mold. At this time, rotate the limit bolt (942) in sequence so that the limit bolt (942) and the grinding head (943) are separated from each other, thereby realizing the replacement of the grinding head (943).
