Description

Technical Field

[0001] This utility model relates to the field of mold processing and positioning, and in particular to a mold processing and positioning device. Background Technology

[0002] In the mold manufacturing industry, positioning devices are core auxiliary equipment that ensures the precision of mold processing. Their positioning stability directly determines the dimensional accuracy, geometric tolerances, and surface quality of the mold. As the mold industry develops towards higher precision and more diverse specifications, different types of molds (such as cylindrical stamping dies and square injection molds) place higher demands on the adaptability and ease of operation of positioning devices.

[0003] Existing mold processing positioning devices generally suffer from two major problems: First, the positioning structure lacks versatility. Most positioning devices adopt an integrated fixed structure with a fixed positioning cavity size, which can only adapt to molds of a single specification. When processing molds of different sizes or shapes, the entire positioning equipment must be replaced or the positioning structure must be complexly modified, which not only increases equipment investment costs but also prolongs production preparation time, seriously affecting processing efficiency. Although some adjustable positioning devices can achieve a certain range of size adaptation, the adjustment process is cumbersome, and the positioning accuracy is easily affected by the clearance of the adjustment mechanism. During processing, vibration can easily cause positioning offset, resulting in mold processing errors exceeding the standard.

[0004] Secondly, the material unloading operation is inconvenient. After the mold is processed, the positioning device fits tightly to the mold surface, and some molds are quite heavy. When manually unloading the material, not only is the labor intensity high, but it is also easy to cause friction and collision with the positioning structure, resulting in scratches on the mold surface or wear on the positioning device.

[0005] To address the aforementioned issues, the industry urgently needs a positioning device with modular adaptability, high positioning accuracy, and stable and efficient material unloading capabilities. This device would solve the technical defects of existing equipment, such as insufficient versatility, poor positioning stability, and inconvenient material unloading. It would also meet the integrated needs of "rapid mold change-precise positioning-convenient material handling" in batch mold production, thereby improving the overall production efficiency and product qualification rate of mold processing. Utility Model Content

Through the modular arrangement of the first positioning square frame, the second positioning square frame, and the cylindrical mold positioning frame, the operator can assemble and install a suitable modular positioning frame according to the size of the mold to be processed.

[0010] Preferably, sleeves are fixedly connected to both sides of the front and back of the positioning box, and a connecting frame is slidably connected inside the sleeve. The end of the connecting frame away from the sleeve is fixedly connected to the movable plate.

[0011] Preferably, mounting blocks are fixedly connected to both sides of the top of the first positioning square frame, the second positioning square frame, and the cylindrical mold positioning frame. Threaded holes are provided on both sides of the top of the first positioning square frame, the second positioning square frame, and the positioning box. A bolt is provided on the top of the mounting block, and the bottom of the bolt passes through the mounting block and is threadedly connected to the threaded hole.

[0012] Preferably, the first positioning square frame, the second positioning square frame, the cylindrical mold positioning frame, and the positioning box all have slots on both sides.

[0013] Compared with related technologies, the mold processing positioning device provided by this utility model has the following beneficial effects:

[0014] 1. This utility model, through the combination of a first positioning frame, a second positioning frame, and a cylindrical mold positioning frame, allows the operator to flexibly assemble and install suitable positioning modules according to the actual size of the mold to be processed, without replacing the entire positioning equipment, greatly improving the versatility of the device. At the same time, the lifting rod in the bottom opening of the positioning box is linked with the lifting mechanism. After processing, the lifting mechanism can be adjusted to drive the lifting rod to rise, easily lifting the mold and avoiding damage to the mold caused by friction between the mold and the positioning structure during manual unloading.

This device has the advantages of good positioning effect and convenient unloading.

[0015] 2. This utility model adopts a connecting rod hinge structure between the slider and the movable plate in the drive box through the lifting mechanism. When the slider slides left and right in the drive box, the horizontal movement is converted into the vertical lifting and lowering of the movable plate through the connecting rod, thereby driving the lifting rod to move.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1 to 4A mold processing positioning device includes: a base plate 1, a lifting mechanism on the top of the base plate 1, a positioning box 2 fixedly connected to the top of the base plate 1 via a bracket, a first positioning square frame 5 on the inner wall of the positioning box 2, a second positioning square frame 6 on the inner wall of the first positioning square frame 5, a cylindrical mold positioning frame 7 on the inner wall of the second positioning square frame 6, an opening 3 at the bottom of the inner wall of the positioning box 2, a lifting rod 4 inside the opening 3, and the lifting mechanism can adjust the lifting rod 4 to facilitate material unloading. The device utilizes the first positioning square frame 5, the second positioning square frame 6, and the cylindrical mold... The modular design of the positioning frame 7 allows the operator to assemble and install suitable modular positioning frames according to the size of the mold to be processed. In actual use, the surface of the threaded rod is equipped with a retractable protective sleeve to prevent impurities from adhering to the surface of the threaded rod. The retractable protective sleeve is a common existing technology and is common knowledge to those skilled in the art, so it will not be described in detail here. The bottoms of the first positioning frame 5, the second positioning frame 6, and the cylindrical mold positioning frame 7 are all in contact with the bottom of the inner wall of the positioning box 2. For example, when the size of the mold to be processed matches the inner wall size of the second positioning frame 6, the operator... Disassemble the cylindrical mold positioning frame 7, then place the mold into the second positioning square frame 6. The inner wall of the second positioning square frame 6 fits against the mold surface to position the mold. When disassembling the cylindrical mold positioning frame 7, the operator first removes the bolts 16 on the surface of the top mounting block 15 of the cylindrical mold positioning frame 7, then rotates the handle to separate the first threaded rod 20 from the insertion port 18 on the surface of the cylindrical mold positioning frame 7, thereby releasing the double fixation of the cylindrical mold positioning frame 7. The operator can then remove the cylindrical mold positioning frame 7 upwards. The top of the base plate 1 has an installation opening for... The base plate 1 is fixed in the preset position by the connector. All standard parts used in this utility model can be purchased from the market. Irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts 16, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art, and this application will not describe them in detail.

[0023] refer to Figure 2 As shown, the lifting mechanism includes a drive box 8 fixedly connected to the top of the base plate 1. Slider 9 is slidably connected to both sides inside the drive box 8. A connecting rod 10 is hinged to the top of the slider 9. A movable plate 11 is provided on the top of the base plate 1. The bottom of the lifting rod 4 is fixedly connected to the top of the movable plate 11. The end of the connecting rod 10 away from the slider 9 is hinged to the bottom of the movable plate 11.

[0024] It should be noted that the lifting mechanism adopts a hinged structure between the slider 9 and the movable plate 11 in the drive box 8 and the connecting rod 10. When the slider 9 slides left and right in the drive box 8, the horizontal movement is converted into the vertical lifting and lowering of the movable plate 11 through the connecting rod 10, which in turn drives the lifting rod 4 to move.

[0025] refer to Figure 2 As shown, a positive and negative threaded rod is rotatably connected inside the drive box 8. The positive and negative threaded rod is threadedly connected to the slider 9. A servo motor 12 is fixedly connected to the right side of the drive box 8. The output end of the servo motor 12 is fixedly connected to the positive and negative threaded rod.

[0026] It should be noted that the combined drive method of the positive and negative threaded rod and the servo motor 12, with the output end of the servo motor 12 fixedly connected to the positive and negative threaded rod via a coupling, enables precise control of the rotation of the threaded rod. The threaded connection design between the positive and negative threaded rod and the slider 9 allows the two sliders 9 to slide synchronously in opposite directions along the threaded rod when the motor starts. This, in turn, drives the movable plate 11 to rise and fall smoothly via the connecting rod 10, ensuring that the lifting height of the lifting rod 4 can be precisely adjusted according to the mold thickness. This avoids situations where the mold is lifted too high, causing it to fall off, or insufficient lifting, making it difficult to remove the material.

[0027] refer to Figure 1 As shown, sleeves 13 are fixedly connected to both sides of the front and back of the positioning box 2. A connecting frame 14 is slidably connected inside the sleeve 13. The end of the connecting frame 14 away from the sleeve 13 is fixedly connected to the movable plate 11.

[0028] It should be noted that: This device has sleeves 13 on both the front and back sides of the positioning box 2. One end of the connecting frame 14 is fixed to the movable plate 11, and the other end is embedded in the sleeve 13 and can slide up and down, forming a guiding support for the movable plate 11. This design strictly limits the lifting trajectory of the movable plate 11 to the vertical direction, avoiding tilting or deviation during the lifting process, ensuring that the lifting rod 4 is always precisely aligned with the opening 3 of the positioning box 2, and reducing frictional wear between components. At the same time, the cooperation between the connecting frame 14 and the sleeve 13 enhances the connection stability between the movable plate 11 and the positioning box 2, enabling the lifting mechanism to maintain stable operation even when driving heavy molds, improving the load-bearing capacity and operational reliability of the device, and providing a stable guarantee for mass mold processing.

[0029] refer to Figure 4 As shown, mounting blocks 15 are fixedly connected to both sides of the top of the first positioning frame 5, the second positioning frame 6, and the cylindrical mold positioning frame 7. Threaded holes are provided on both sides of the top of the first positioning frame 5, the second positioning frame 6, and the positioning box 2. Bolts 16 are provided on the top of the mounting blocks 15, and the bottom of the bolts 16 penetrates the mounting blocks 15 and is threadedly connected to the threaded holes.

[0030] It should be noted that this device has mounting blocks 15 on both sides of the top of each positioning frame. These mounting blocks 15, along with the threaded holes on the positioning box 2 and each positioning frame, are fixedly connected to the corresponding structure using bolts 16, achieving precise fixation of the positioning frame. The bolt 16 connection not only ensures the strong connection between the positioning frame and the positioning box 2, preventing displacement of the positioning frame due to vibration during processing and ensuring mold positioning accuracy, but also simplifies the assembly and disassembly of the positioning frame. Operators only need to use conventional tools to tighten and loosen the bolts 16, quickly replacing and assembling the positioning modules. This design improves the stability of the positioning frame installation and simplifies the module replacement process, enabling the device to quickly adapt to the processing needs of molds of different sizes, reducing equipment adjustment time, improving production efficiency, and extending the service life of the positioning frame due to the repeatability of the bolt 16 connection.

[0031] refer to Figure 2 As shown, the first positioning frame 5, the second positioning frame 6, the cylindrical mold positioning frame 7, and the positioning box 2 all have insertion ports 18 on both sides. The positioning box 2 is fixedly connected to both sides of the support frame 19. The support frame 19 is internally threaded with a first threaded rod 20, which is inserted into the insertion port 18. The surface of the first threaded rod 20 is fixedly connected with a rotating handle. The first positioning frame 5, the second positioning frame 6, and the positioning box 2 are all fixedly connected to both sides of the top. Guide blocks 17 are fixedly connected to both sides of the top.

[0032] It should be noted that this device, through the cooperation of the socket 18 and the first threaded rod 20, after the positioning frame is installed in place, rotates the handle to drive the first threaded rod 20 on the support frame 19 into the corresponding socket 18, thus reinforcing the positioning frame horizontally. Combined with the vertical fixation of the top bolt 16, this forms a double-fixing structure, effectively enhancing the stability of the positioning frame and preventing it from loosening due to processing vibrations. Simultaneously, the guide blocks 17 on the top of the positioning box 2 and each positioning frame play a guiding role during installation, enabling the operator to quickly align the positioning frame with the installation position, reducing installation deviations and improving module splicing efficiency.

[0033] The working principle of the mold processing positioning device provided by this utility model is as follows: Before using the mold processing positioning device, the entire device must first be inspected to confirm that the base plate 1 has been firmly fixed in the preset position through the mounting port, that there is no looseness in any connecting parts, that the sleeve 13 and the connecting frame 14 fit smoothly, and that the servo motor 12 and the wiring connection are normal. Then, according to the specific size of the mold to be processed, a suitable positioning module is selected. If the mold is cylindrical, a cylindrical mold positioning frame 7 is selected; if it is square and the size is different, a first positioning square frame 5 or a second positioning square frame 6 is selected accordingly to ensure that the inner wall size of the positioning module fits the outer wall of the mold.

[0034] Next, install the positioning module. First, clean the threaded holes on the top of the positioning box 2 to prevent impurities from affecting the connection stability. Then, guided by the guide blocks 17 on the top of the positioning box 2 and each positioning frame, align the selected positioning module with the installation position on the inner wall of the positioning box 2, ensuring that the bottom of the positioning module fits tightly against the bottom of the inner wall of the positioning box 2. For example, with the attached... Figure 2 In the current state, when the size of the mold to be processed matches the inner wall size of the second positioning frame 6, the operator needs to disassemble the cylindrical mold positioning bracket 7, and then place the mold into the second positioning frame 6. The inner wall of the second positioning frame 6 fits against the mold surface to position the mold. When disassembling the cylindrical mold positioning bracket 7, the operator first removes the bolts 16 on the surface of the top mounting block 15 of the cylindrical mold positioning bracket 7, and then rotates the handle to separate the first threaded rod 20 from the insertion port 18 on the surface of the cylindrical mold positioning bracket 7, thereby releasing the double fixation of the cylindrical mold positioning bracket 7. Then the operator can remove the cylindrical mold positioning bracket 7 upwards. The adjustment process for processing molds of other sizes is the same.

[0035] After confirming that the mold is correctly positioned, the processing equipment can be started to process the mold. After the mold is processed, the servo motor 12 is started again to control the positive and negative thread rods to rotate in opposite directions, driving the slider 9 to slide towards the middle. The connecting rod 10 pushes the movable plate 11 to move upward. The lifting rod 4 rises synchronously with the movable plate 11 to lift the mold. The operator lifts the mold with both hands, removes the mold from the positioning module and places it in the designated position. Then, the servo motor 12 is controlled to reset the lifting rod 4. Finally, the positioning device is cleaned.

[0036] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
