Description

Technical Field

[0001] This invention relates to the field of injection molding machine technology, and in particular to a mold adjustment device for an injection molding machine. Background Technology

[0002] Injection molding utilizes the thermophysical properties of plastics to plasticize, melt, and homogenize the material before injecting it into the cavity of a mold. The molten material is then held under pressure, cooled, and solidified within the mold cavity to form the finished product. In some injection molding processes, to obtain a high-density, high-strength, and highly uniform preform, metal powder is often added to the molten material to prepare a slurry with low relative viscosity and a high solid volume fraction. The organic monomers in the slurry are then polymerized to allow the slurry to solidify in situ.

[0003] Injection molding machines are devices that perform injection molding operations by applying clamping force to the mold between a movable plate and a fixed plate using tie rods. Hydraulic cylinders drive the movable plate assembly to a specified stroke. However, when producing different types of products, the position of the hydraulic cylinder's stroke tip needs to be adjusted according to requirements. Therefore, the hydraulic cylinder mounting base is designed to be adjustable. Multiple threaded rods mounted on the mounting base are used to adjust the position of the hydraulic cylinder by rotating these rods, thus adjusting the position of the hydraulic cylinder to adapt to different product injection molding production. When adjusting the mounting base position, multiple threaded rods need to be rotated simultaneously to control the precise translation of the mounting base. However, over time, there is wear and misalignment between each threaded rod and the mounting base. When multiple threaded rods rotate simultaneously, it is difficult to guarantee precise translation of the mounting base. This causes a gap to form between the movable plate assembly and the fixed plate assembly when the hydraulic cylinder pushes them to close the mold, resulting in product defects. Summary of the Invention

[0004] Based on this, it is necessary to provide a mold adjustment device for an injection molding machine to address the aforementioned technical problems. This device uses a locking ring, locking rod, and fine-tuning gear ring to lock together and move synchronously. This allows the adjusting gear plate, central gear ring, and mounting base to move along the adjusting screw, thereby adjusting the position of the mounting base as a whole. The rotating fine-tuning gear ring drives the freely rotating planetary gear, which in turn drives the central gear ring meshing with it. Individual control of the fine-tuning gear ring's rotation controls the corresponding central gear ring to mesh with the adjusting screw, allowing for individual adjustment of different positions of the mounting base. This precise leveling of the mounting base enables the telescopic drive component to push the moving mold assembly and the fixed mold assembly to precisely close the mold.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A mold adjustment device for an injection molding machine includes: a fixed mold assembly, a movable mold assembly, and a telescopic drive component. The movable mold assembly is slidably connected to the fixed mold assembly via a guide shaft inserted therein, and the output end of the telescopic drive component is connected to the movable mold assembly via a connecting rod assembly. It also includes: a mounting base, the telescopic drive component is mounted on the mounting base, the guide shaft is inserted into the mounting base, and an adjusting gear is rotatably connected to the mounting base, the outer ring of the adjusting gear meshing with an adjusting gear corresponding to the guide shaft; A central gear ring is located in the middle of an adjusting gear disk. An inner gear ring is installed on the inner ring of the adjusting gear disk. A planetary gear meshes between the inner gear ring and the central gear ring. An adjusting screw is threadedly connected to the middle of the central gear ring. The adjusting screw is installed correspondingly to the guide shaft. A fine-tuning gear ring is fitted around the outer ring of the adjusting screw. A locking rod corresponding to the planetary gear is inserted into the fine-tuning gear ring, and the locking rod is fixed to the middle of the planetary gear. A locking ring that contacts the locking rod is connected to the fine-tuning gear ring.

[0006] In a preferred embodiment of the mold adjustment device for an injection molding machine provided by the present invention, the central gear ring is rotatably connected to the center of the adjusting gear disc, and the adjusting screw is inserted into the adjusting gear disc. By rotating the central gear ring and moving it along the adjusting screw, the movement of the central gear ring mounted on the mounting base is adjusted, thereby adjusting the position of the mounting base. Furthermore, by controlling the planetary gear and the fine-tuning gear ring to lock and rotate synchronously, the fine-tuning gear ring can be controlled to move synchronously with the adjusting gear disc and the inner gear ring, and the central gear ring can be controlled to move synchronously with the adjusting gear disc. When the planetary gear can rotate freely with the fine-tuning gear ring, the fine-tuning gear ring can be controlled independently to drive the planetary gear to move, and drive the central gear ring to rotate independently, thereby achieving the purpose of independently controlling the rotation of the central gear ring and the corresponding adjusting screw, and precisely controlling the mounting base.

[0007] In a preferred embodiment of the mold adjustment device for an injection molding machine provided by the present invention, at least two planetary gears are provided, the locking rod passes through the fine-tuning gear ring, and the locking ring is located on the side of the fine-tuning gear ring away from the planetary gears. The locking ring is sleeved with the adjusting screw, and the end of the locking rod is locked by moving the locking ring, thereby locking the fine-tuning gear ring, the locking rod and the locking ring together.

[0008] In a preferred embodiment of the mold adjustment device for an injection molding machine provided by the present invention, the outer ring of the fine-tuning gear ring is engaged with a fine-tuning active gear ring by teeth, and individual drive adjustment is performed by installing a corresponding fine-tuning active gear ring on one side of each fine-tuning gear ring.

[0009] In a preferred embodiment of the mold adjustment device for an injection molding machine provided by the present invention, a lifting ring is provided on the side of the locking ring away from the fine-tuning gear ring, which is sleeved with the adjusting screw. A lifting plate is provided on the other side of the lifting ring, which is slidably connected to the inner cavity of the mounting base. The contact surface between the lifting plate and the lifting ring is inclined. By moving the lifting plate laterally, the inclined front end of the lifting plate extends against the bottom surface of the lifting ring, and the extended lifting ring pushes the locking ring toward the fine-tuning gear ring, controlling the locking ring to contact the locking rod. Conversely, the contact between the locking ring and the locking rod is released, thereby realizing the control of the up and down movement of the locking ring.

[0010] In a preferred embodiment of the mold adjustment device for an injection molding machine provided by the present invention, each of the lifting plates is connected to a lifting mechanism for controlling the reciprocating lateral movement of the lifting plate.

[0011] As a preferred embodiment of the mold adjustment device for an injection molding machine provided by the present invention, the lifting mechanism includes a shifting gear plate connected to the adjusting gear plate and an adjusting block located on one side of the shifting gear plate. The adjusting block is slidably connected to the mounting base. A positioning arc-shaped block is fixed on the side of the adjusting block near the teeth of the shifting gear plate. The adjusting block is connected to a reset elastic element. When the adjusting gear plate rotates, it drives the adjusting gear plate to rotate. At this time, the shifting gear plate rotates synchronously with the adjusting gear plate. Since each positioning arc-shaped block is inserted between the teeth on the shifting gear plate, when the shifting gear plate rotates, it pushes the positioning arc-shaped block and the adjusting block to move outward, thereby pushing the lifting plate to move. This controls the lifting ring to extend against the locking ring, and the locking ring locks the locking rod in a linkage control. Conversely, when the adjusting gear plate does not drive the adjusting gear plate, each positioning arc-shaped block is inserted between the teeth on the shifting gear plate and resets. The lifting plate resets and releases the extension of the lifting ring, and the locking ring releases the locking rod, thus achieving the purpose of synchronous linkage control.

[0012] In a preferred embodiment of the mold adjustment device for an injection molding machine provided by the present invention, a reset elastic element is installed on the side of the adjustment block away from the actuating toothed disc. The front end of the positioning arc block has an arc-shaped structure and corresponds to the teeth on the actuating toothed disc. The reset elastic element pushes the adjustment block and the positioning arc block to reset, thereby controlling the lifting plate to release the lifting ring from its extension.

[0013] In a preferred embodiment of the mold adjustment device for an injection molding machine provided by the present invention, a drive motor is mounted on the fine-tuning active gear ring, and the drive motor is mounted on the mounting base.

[0014] In a preferred embodiment of the mold adjustment device for an injection molding machine provided by the present invention, the adjusting gear disc engages with a driving gear disc via teeth to drive the adjusting gear disc.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a mold adjustment device for an injection molding machine. The rotation of the adjusting gear disc drives the outer ring to rotate. At this time, the adjusting gear disc drives the inner gear ring to rotate synchronously. By controlling the locking ring to abut against the end of the locking rod, the locking ring, the locking rod and the fine-tuning gear ring are locked together and move synchronously. Thus, the rotating adjusting gear disc drives the central gear ring threadedly connected to the adjusting screw to rotate synchronously. This causes the adjusting gear disc, the central gear ring and the mounting base to move along the adjusting screw, thereby adjusting the position of the mounting base as a whole. When it is necessary to adjust different positions of the mounting base individually, by rotating the fine-tuning gear ring at the corresponding position on the mounting base, and at this time the locking ring is not in contact with the locking rod, the planetary gear and the locking rod can rotate freely with the fine-tuning gear ring. The rotating fine-tuning gear ring drives the central gear ring meshed with it to rotate through the freely rotating planetary gear, thereby controlling the rotation of the corresponding central gear ring and the adjusting screw thread. Therefore, by controlling the rotation of the fine-tuning gear ring individually, the corresponding central gear ring can be meshed with the adjusting screw, and different positions of the mounting base can be adjusted individually. The mounting base is precisely leveled, so that the telescopic drive component pushes the moving mold assembly and the fixed mold assembly to precisely close the mold.

[0016] 2. The present invention provides a mold adjustment device for an injection molding machine. When the adjusting gear disk rotates, it drives the adjustment gear disk to rotate. At this time, the actuating gear disk rotates synchronously with the adjusting gear disk. Since each positioning arc block is inserted between the teeth on the actuating gear disk, when the actuating gear disk rotates, it pushes the positioning arc block and the adjustment block to move outward, thereby pushing the lifting plate to move. This controls the lifting ring to extend against the locking ring, and the locking ring locks the locking rod in a linkage control. Conversely, when the adjusting gear disk does not drive the adjustment gear disk, each positioning arc block is reset between the teeth on the actuating gear disk. The lifting plate resets and releases the extension of the lifting ring. The locking ring releases the locking rod, thus achieving the purpose of synchronous linkage control.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0021] As described in the background art, after long-term use, there is a certain amount of wear and misalignment between each threaded rod and the mounting base. When multiple threaded rods rotate simultaneously, it is difficult to ensure that the mounting base moves accurately. This causes a gap to form between the movable plate assembly and the fixed plate assembly when the hydraulic cylinder pushes them to close the mold, resulting in product defects.

[0022] For details, please refer to Figures 1 to 6 A mold adjustment device for an injection molding machine includes: a fixed mold assembly 1, a movable mold assembly 2, and a telescopic drive component 6. The movable mold assembly 2 is slidably connected to the fixed mold assembly 1 via a guide shaft 3 inserted therein, and the output end of the telescopic drive component 6 is connected to the movable mold assembly 2 via a connecting rod assembly 4. It also includes: a mounting base 5, the telescopic drive 6 is mounted on the mounting base 5, the guide shaft 3 is inserted into the mounting base 5, and an adjusting gear 7 is rotatably connected to the mounting base 5, the outer ring of the adjusting gear 7 meshes with an adjusting gear 8 corresponding to and connected to the guide shaft 3; A central gear ring 13 is disposed in the middle of the adjusting gear disk 8. An inner gear ring 12 is installed on the inner ring of the adjusting gear disk 8. A planetary gear 14 meshes between the inner gear ring 12 and the central gear ring 13. An adjusting screw 11 is threadedly connected to the middle of the central gear ring 13. The adjusting screw 11 is installed correspondingly to the guide shaft 3. A fine-tuning gear ring 15 is sleeved on the outer ring of the adjusting screw 11. A locking rod 17 corresponding to the planetary gear 14 is inserted into the fine-tuning gear ring 15, and the locking rod 17 is fixed to the middle of the planetary gear 14. A locking ring 19 that contacts the locking rod 17 is connected to the fine-tuning gear ring 15.

[0023] This invention provides a mold adjustment device for an injection molding machine. The rotation of the adjusting gear 7 drives the outer ring of the adjusting gear 8 to rotate. At this time, the adjusting gear 8 drives the inner gear ring 12 to rotate synchronously. By controlling the locking ring 19 to abut against the end of the locking rod 17, the locking ring 19, locking rod 17, and fine-tuning gear ring 15 are locked together and move synchronously. Thus, the rotating adjusting gear 8 drives the central gear ring 13, which is threadedly connected to the adjusting screw 11, to rotate synchronously. This causes the adjusting gear 8, the central gear ring 13, and the mounting base 5 to move along the adjusting screw 11, thereby adjusting the position of the mounting base 5 as a whole. When it is necessary to adjust different positions of the mounting base 5 individually, the adjusting gear 7 rotates the inner gear ring 12 to rotate synchronously. The fine-tuning gear ring 15 is positioned on the mounting base 5, and the locking ring 19 is not in contact with the locking rod 17. The planetary gear 14 and the locking rod 17 can rotate freely with the fine-tuning gear ring 15. The rotating fine-tuning gear ring 15 drives the central gear ring 13, which meshes with it, to rotate through the freely rotating planetary gear 14. This controls the corresponding central gear ring 13 to rotate with the adjusting screw 11. Therefore, by controlling the rotation of the fine-tuning gear ring 15 alone, the corresponding central gear ring 13 can be meshed with the adjusting screw 11, and different positions of the mounting base 5 can be adjusted individually to precisely level the mounting base 5. This allows the telescopic drive 6 to push the moving mold assembly 2 and the fixed mold assembly 1 to precisely close the mold.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Example

[0027] Please refer to Figures 1 to 2A mold adjustment device for an injection molding machine includes a movable mold assembly 2 slidably connected to a fixed mold assembly 1 via a guide shaft 3 inserted therein. The output end of a telescopic drive 6 is connected to the movable mold assembly 2 via a connecting rod assembly 4. The telescopic drive 6 is mounted on a mounting base 5, with the guide shaft 3 inserted into the mounting base 5. An adjusting gear 7 is rotatably connected to the mounting base 5, and the outer ring of the adjusting gear 7 meshes with an adjusting gear 8 corresponding to the guide shaft 3. The telescopic drive 6 drives the connecting rod assembly 4 to move, thereby pushing the movable mold assembly 2 to move stably along the guide shaft 3, adjusting the position of the mounting base 5, adjusting the installation position of the telescopic drive 6, and rotating the adjusting gear 7 to drive the multiple adjusting gears 8 meshing on their outer rings to rotate simultaneously. It is worth mentioning that, such as Figures 3 to 6 As shown, the central gear ring 13 is located in the middle of the adjusting gear disk 8. An inner gear ring 12 is installed on the inner ring of the adjusting gear disk 8. A planetary gear 14 meshes between the inner gear ring 12 and the central gear ring 13. An adjusting screw 11 is threadedly connected to the middle of the central gear ring 13. The adjusting screw 11 is correspondingly installed with the guide shaft 3. The central gear ring 13 is rotatably connected to the middle of the adjusting gear disk 8, and the adjusting screw 11 is inserted into the adjusting gear disk 8. By rotating the central gear ring 13, it moves along the adjusting screw 11, thereby adjusting the movement of the central gear ring 13 installed with the mounting base 5, and thus adjusting... The position of the mounting base 5 is adjusted, and when the planetary gear 14 and the fine-tuning gear ring 15 are locked and rotated synchronously, the fine-tuning gear ring 15 can be controlled to move synchronously with the adjusting gear plate 8 and the inner gear ring 12, and the central gear ring 13 can be controlled to move synchronously with the adjusting gear plate 8. When the planetary gear 14 can rotate freely with the fine-tuning gear ring 15, the fine-tuning gear ring 15 can be controlled to drive the planetary gear 14 to move independently, and drive the central gear ring 13 to rotate independently, so as to achieve the purpose of controlling the rotation of the central gear ring 13 and the corresponding adjusting screw 11 independently, and to accurately control the mounting base 5.

[0028] In addition, such as Figures 3 to 6As shown, the fine-tuning gear ring 15 is sleeved on the outer ring of the adjusting screw 11. A locking rod 17 corresponding to the planetary gear 14 is inserted into the fine-tuning gear ring 15, and the locking rod 17 is fixed to the middle of the planetary gear 14. A locking ring 19 that contacts the locking rod 17 is connected to the fine-tuning gear ring 15. By moving the locking ring 19 toward the locking rod 17, the locking rod 17 and the locking ring 19 are locked. Since the locking ring 19 and the fine-tuning gear ring 15 are slidably inserted, the fine-tuning gear ring 15, the locking rod 17, and the locking ring 19 are locked together, thus... The planetary gear 14 and the fine-tuning gear ring 15 are locked; and when the locking ring 19 is not in contact with the locking rod 17, the planetary gear 14 rotates freely through the locking rod 17 and the fine-tuning gear ring 15. When the fine-tuning gear ring 15 drives the locking rod 17 and the planetary gear 14 to move, the planetary gear 14 meshes with the inner gear ring 12 and rotates. The rotating planetary gear 14 drives the central gear ring 13 meshing with it to rotate, thereby controlling the rotation of the corresponding central gear ring 13 and the corresponding adjusting screw 11, and precisely adjusting the different positions of the mounting base 5.

[0029] It is worth mentioning that, such as Figure 5 and Figure 6 As shown, at least two planetary gears 14 are provided. The locking rod 17 passes through the fine-tuning gear ring 15, and the locking ring 19 is located on the side of the fine-tuning gear ring 15 away from the planetary gear 14. The locking ring 19 is sleeved with the adjusting screw 11. By moving the locking ring 19, the end of the locking rod 17 is locked, and the fine-tuning gear ring 15, the locking rod 17 and the locking ring 19 are locked together.

[0030] Furthermore, the outer ring of the fine-tuning gear ring 15 is engaged with a fine-tuning active gear ring 16 through tooth meshing. A drive motor is installed on the fine-tuning active gear ring 16. By installing a corresponding fine-tuning active gear ring 16 on one side of each fine-tuning gear ring 15 and driving it individually through the drive motor, the drive motor is installed in relation to the mounting base 5. The adjusting gear plate 7 is engaged with a drive gear plate 9 through tooth meshing to drive the adjusting gear plate 7. The adjusting gear plate 7 is driven by the rotating locking ring 19, which facilitates the synchronous adjustment of multiple positions of the mounting base 5. Example

[0031] The mold adjustment device for an injection molding machine provided in Example 1 is further optimized, specifically, as follows: Figures 4 to 5As shown, a lifting ring 18 is provided on the side of the locking ring 19 away from the fine-tuning gear ring 15, which is sleeved with the adjusting screw 11. On the other side of the lifting ring 18, a lifting plate 21 is provided, which is slidably connected to the inner cavity of the mounting base 5. The contact surface between the lifting plate 21 and the lifting ring 18 is inclined. By moving the lifting plate 21 laterally, the inclined front end of the lifting plate 21 extends against the bottom surface of the lifting ring 18, and the extended lifting ring 18 pushes the locking ring 19 toward the fine-tuning gear ring 15, and controls the locking ring 19 to contact the locking rod 17. Conversely, the contact between the locking ring 19 and the locking rod 17 is released, thereby realizing the control of the up and down movement of the locking ring 19.

[0032] It is worth mentioning that, such as Figures 4 to 5 As shown, each lifting plate 21 is connected to a lifting mechanism for controlling the reciprocating lateral movement of the lifting plate 21. The lifting mechanism includes a shifting gear 10 connected to the adjusting gear 7 and an adjusting block 20 located on one side of the shifting gear 10. The adjusting block 20 is slidably connected to the mounting base 5. A positioning arc-shaped block 23 is fixed on the side of the adjusting block 20 near the teeth of the shifting gear 10. The adjusting block 20 is connected to the reset elastic element 22. When the adjusting gear 7 rotates, driving the adjusting gear 8 to rotate, the shifting gear 10 rotates synchronously with the adjusting gear 7. Due to the positioning arc-shaped block 23, the adjusting plate 20 rotates laterally. Block 23 is inserted between the teeth on the actuating gear 10. When the actuating gear 10 rotates, it pushes the positioning arc block 23 and the adjusting block 20 to move outward, thereby pushing the lifting plate 21 to move. This controls the lifting ring 18 to extend the locking ring 19, and the locking ring 19 locks the locking rod 17 in a linkage control. Conversely, when the adjusting gear 7 does not drive the adjusting gear 8, each positioning arc block 23 is inserted between the teeth on the actuating gear 10 and resets. The lifting plate 21 resets and releases the extension of the lifting ring 18, and the locking ring 19 unlocks the locking rod 17, thus achieving the purpose of synchronous linkage control.

[0033] Preferred, such as Figure 5 As shown, a reset elastic element 22 is installed on the side of the adjusting block 20 away from the actuating toothed disc 10. The front end of the positioning arc block 23 has an arc-shaped structure and corresponds to the teeth on the actuating toothed disc 10. The reset elastic element 22 pushes the adjusting block 20 and the positioning arc block 23 to reset, thereby controlling the lifting plate 21 to release the lifting ring 18 from the extension.

[0034] The process of using the mold adjustment device of the injection molding machine provided by the present invention is as follows: The adjustment gear 7 rotates, driving the adjustment gear 8 engaged with the outer ring to rotate. At this time, the adjustment gear 8 drives the inner gear ring 12 to rotate synchronously. By controlling the locking ring 19 to abut against the end of the locking rod 17, the locking ring 19, the locking rod 17 and the fine adjustment gear ring 15 are locked together and move synchronously. Therefore, the rotating inner gear ring 12 drives the planetary gear 14 to move synchronously, thereby driving the central gear ring 13 engaged with the planetary gear 14 to move synchronously. Thus, the rotating adjustment gear 8 drives the central gear ring 13 to rotate synchronously, thereby controlling the central gear ring 13 to engage with the adjustment screw 11 through the thread, so that the adjustment gear 8 and the central gear ring 13 together with the mounting base 5 move along the adjustment screw 11, thereby adjusting the position of the mounting base 5 as a whole. When it is necessary to adjust different positions of the mounting base 5 individually, by rotating the fine-tuning gear ring 15 at the corresponding position on the mounting base 5, and at this time the locking ring 19 is not in contact with the locking rod 17, the planetary gear 14 and the locking rod 17 can rotate freely with the fine-tuning gear ring 15. At this time, the rotating fine-tuning gear ring 15 drives multiple locking rods 17 and planetary gear 14 to move. At this time, the planetary gear 14 meshes with the teeth of the inner gear ring 12 and rotates. The rotating planetary gear 14 drives the central gear ring 13 that meshes with it to rotate, thereby controlling the corresponding central gear ring 13 to rotate with the adjusting screw 11. Therefore, by controlling the rotation of the fine-tuning gear ring 15 individually, the corresponding central gear ring 13 can be controlled to mesh with the adjusting screw 11, and different positions of the mounting base 5 can be adjusted individually.
