Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold for a printer support frame. Background Technology

[0002] Injection molds consist of two parts: a moving mold and a fixed mold. The moving mold is installed on the moving platen of the injection molding machine, and the fixed mold is installed on the fixed platen of the injection molding machine. During injection molding, the moving mold and the fixed mold close to form the gating system and the cavity. When the mold is opened, the moving mold and the fixed mold separate to remove the plastic product.

[0003] When existing injection molds are in use, the guide hole needs to be replaced after it wears out. However, the new guide hole needs to be machined with high precision to fit the size of the mounting hole. When the size of the guide hole deviates, it cannot be installed, so it must be re-machined, resulting in material waste. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a printer support bracket injection mold to solve the technical problem that when the processing dimensions of the guide hole are deviated, it cannot be installed, which requires reprocessing and results in material waste.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a printer support frame injection mold, including a first mold, wherein mounting holes are provided at the four corners of the first mold, and guide holes are provided inside the mounting holes, and the position of the mounting holes is adjusted within the mounting holes by an adjustment mechanism;

[0006] The adjustment mechanism includes a first sliding groove and a second sliding groove, and a first push block and a second push block are slidably connected inside the first sliding groove and the second sliding groove, respectively.

[0007] By adopting the above technical solution, the position of the guide hole within the mounting hole can be flexibly adjusted to accommodate guide holes of different sizes. Through precise adjustment of the adjustment mechanism, it can be ensured that the guide hole maintains a high-precision fit with other parts of the mold, thereby improving the quality and precision of injection molded products.

[0008] Furthermore, a first threaded rod is rotatably connected inside the first sliding groove, and the first threaded rod is threadedly connected to the first push block.

[0009] By adopting the above technical solution, the first push block can slide along the first sliding groove by rotating the first threaded rod. Since the top of the first push block is inclined, when the push block slides, its inclined top can gradually contact the outer wall of the guide hole and apply pressure, thereby pushing the guide hole to move in the mounting hole.

[0010] Furthermore, the second sliding groove is internally rotatably connected to a second threaded rod, which is threadedly connected to the second push block.

[0011] By adopting the above technical solution, the second pusher can slide along the second sliding groove by rotating the second threaded rod and push the guide hole to move in the mounting hole. Since the top of the second pusher is also inclined, it can work together with the first pusher to accurately adjust and position the guide hole from two directions.

[0012] Furthermore, a top post is threaded onto one side of the mounting hole, and the top post is used for limiting the position.

[0013] By adopting the above technical solution, additional stability and limiting function are provided for the assembly and adjustment of the mold. When adjusting the position of the guide hole, the ejector pin can hold one side of the guide hole to prevent it from moving or misaligning during the adjustment process, ensuring that the guide hole is accurately positioned in the required position and improving the overall mold closing stability and accuracy.

[0014] Furthermore, the first mold includes a front plate and a rear plate, which are fixedly connected by bolts.

[0015] By adopting the above technical solution, the mold structure is made more robust and stable through bolt fixing. This connection method can ensure that the mold can withstand greater pressure and impact during the injection molding process, thereby improving the service life of the mold and the quality of the injection molded products.

[0016] Furthermore, the guide hole includes a limiting shoulder, and one side of the guide hole abuts against one side of the rear plate.

[0017] By adopting the above technical solution, additional support and limiting function are provided for the guide hole. When the guide hole is installed in the mounting hole, its limiting shoulder can abut against one side of the rear plate, thereby preventing the guide hole from moving or misaligning during installation.

[0018] Furthermore, the front panel has four grooves on its front side, and the four grooves are arranged opposite to the mounting holes.

[0019] By adopting the above technical solution, it is possible to further strengthen and stabilize the mold. By opening a groove on the front side of the front plate, additional fixing parts and pressure blocks can be easily installed, which helps to improve the overall stability and precision of the mold and ensure the quality of injection molded products.

[0020] Furthermore, a pressure block is fixedly connected to the inside of the groove by bolts, and the bottom of the pressure block abuts against the top of the guide hole.

[0021] By adopting the above technical solution, the pressure block is fixed in the groove with bolts, and its bottom abuts against the top of the guide hole. This can further compress the guide hole, prevent it from moving during the injection molding process, help improve the quality and precision of the injection molded products, and ensure the long-term stable operation of the mold.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model, by setting a first mold, mounting holes, and an adjustment mechanism, uses the first mold as the base of the injection mold and sets mounting holes on it, so that different parts can be installed and disassembled as needed, increasing the flexibility of the mold and enabling quick replacement when the guide hole is worn, reducing maintenance costs. The adjustment mechanism further improves the adaptability of the mold, allowing the mold to be precisely adjusted according to the specific size of the guide hole, ensuring the accuracy of subsequent mold closing, and solving the technical problem that when the processing size of the guide hole is deviated, it cannot be installed, and reprocessing is required, resulting in material waste.

[0024] 2. This utility model uses a pressure block with a groove and a guide hole for pressing. The pressure block is used to press the guide hole to ensure its positional stability and accuracy during the injection molding process. The guide hole plays the role of guiding the guide rod in the mold, and its position accuracy directly affects the dimensional accuracy of the mold closing. By pressing the guide hole with the pressure block, it can effectively prevent it from moving during the mold closing process, thereby ensuring the injection molding accuracy.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] Example 1:

[0034] A printer support frame injection mold, such as Figures 1-6 As shown, it includes a first mold 1, and mounting holes 2 are provided at the four corners of the first mold 1. Guide holes 3 are provided inside the mounting holes 2. The position of the mounting holes 2 within the mounting holes 2 is adjusted by an adjustment mechanism 4.

[0035] The adjustment mechanism 4 includes a first sliding groove 401 and a second sliding groove 402. The first sliding groove 401 and the second sliding groove 402 are respectively slidably connected to the interior of the first sliding groove 403 and the second sliding groove 404. The introduction of the adjustment mechanism 4 allows the operator to precisely adjust the position of the guide hole 3 according to the specific situation, thereby ensuring the accurate mold closing of the two molds during the injection molding process and helping to improve the mold closing accuracy.

[0036] See Figure 3 The first sliding groove 401 is internally rotatably connected to a first threaded rod 405, which is threadedly connected to a first push block 403. The position of the push block can be precisely controlled by rotating the threaded rod. This mechanical transmission method is not only stable and reliable, but also easy to operate. The top of the push block is inclined, which allows pressure to be gradually applied to the guide hole 3 during the movement of the push block, improving the adjustment accuracy and achieving reliable limiting.

[0037] See Figure 3 The second sliding groove 402 is internally rotatably connected to a second threaded rod 406, which is threadedly connected to a second push block 404. This allows the second push block 404 to move precisely within the sliding groove, improving the adjustment accuracy of the mold and ensuring high stability and reliability of the mold during adjustment. Working in conjunction with the first push block 403, it can precisely adjust the guide hole 3 from two directions, ensuring that the guide hole 3 is in the optimal position within the mounting hole 2.

[0038] See Figure 3 One side of the mounting hole 2 is threaded with a top post 407. The top post 407 is used for limiting and pressing against the guide hole 3, which improves the adjustment accuracy of the mold and reduces the error risk during operation. The threaded connection of the top post 407 makes it easy to install, adjust and disassemble, which facilitates the maintenance and upkeep of the mold.

[0039] See Figure 4 The first mold 1 includes a front plate 101 and a rear plate 102, which are fixedly connected by bolts. The bolt connection makes the mold structure more robust and stable, which not only improves the load-bearing capacity of the mold, but also enables the mold to maintain high precision and stability during injection molding. In addition, the bolt connection makes the mold easy to disassemble and assemble, and facilitates the maintenance and replacement of the mold.

[0040] See Figure 4 The guide hole 3 includes a limiting shoulder 301. One side of the guide hole 3 abuts against one side of the back plate 102. When the guide hole 3 is installed in the mounting hole 2, its limiting shoulder 301 can abut against one side of the back plate 102, which improves the adjustment accuracy of the mold and ensures the positional stability of the guide hole 3 in the mounting hole 2. This helps to ensure that the guide hole 3 is accurately positioned in the required position and improves the overall accuracy and stability of the mold.

[0041] The implementation principle of this utility model is as follows: First, the mold is composed of a first mold 1. The four corners of the first mold 1 are provided with mounting holes 2. The interior of the mounting holes 2 is reserved for mounting guide holes 3. The adjustment mechanism 4 is provided with a first sliding groove 401 and a second sliding groove 402 near the mounting holes 2. The first push block 403, the second push block 404, the first threaded rod 405 and the second threaded rod 406 are used to adjust the position and stability of the guide holes 3.

[0042] When it is necessary to replace the guide hole 3, insert the new guide hole 3 into the mounting hole 2. The limiting shoulder 301 of the guide hole 3 abuts against one side of the rear plate 102 to ensure that the guide hole 3 will not fall completely into the mounting hole 2.

[0043] Rotate the top post 407 so that it enters the mounting hole 2 and presses against one side of the guide hole 3, providing an initial limiting effect for subsequent push block adjustment. Rotate the first threaded rod 405 and the second threaded rod 406. Since the first push block 403 and the second push block 404 are threadedly connected to the first threaded rod 405 and the second threaded rod 406 respectively, and the top of the push block is inclined at an angle towards the center of the guide hole 3, the push block will slide along the sliding groove and approach the guide hole 3 as the threaded rod rotates. The inclined top of the first push block 403 and the second push block 404 gradually contacts the outer wall of the guide hole 3 and applies pressure, pushing the guide hole 3 towards the center of the mounting hole 2, while restricting its radial movement. After repeated adjustment, the guide hole 3 and the corresponding guide post are aligned, and at the same time, it is restricted by the limiting shoulder 301 to prevent the guide hole 3 from moving. After the adjustment is completed, the mold can be put back into use for injection molding.

[0044] Example 2:

[0045] See Figure 5 and Figure 6 The front plate 101 has four grooves 5 on its front side. The four grooves 5 are arranged opposite to the mounting holes 2. The grooves 5 on the front side of the front plate 101 provide installation space for the pressure block 6, so that the guide hole 3 can be reliably installed. The four grooves 5 are arranged opposite to the mounting holes 2, which makes the guide hole 3 more structurally stable.

[0046] See Figure 5 and Figure 6 The groove 5 is fixedly connected to the pressure block 6 by bolts. The bottom of the pressure block 6 abuts against the top of the guide hole 3. The bolt connection of the pressure block 6 makes it easy to install and disassemble, which facilitates the maintenance and replacement of the mold and ensures the stability and reliability of the mold during long-term operation.

[0047] The implementation principle of this utility model is as follows: First, a groove 5 is opened on the front side of the front plate 101, and the pressure block 6 is fixedly connected in the groove 5 by bolts. The bottom of the pressure block 6 abuts against the top of the guide hole 3, further pressing the guide hole 3 and increasing its stability, so that the guide hole 3 is stably installed in the mounting hole 2 and maintains good fitting accuracy with the mounting hole 2. After that, the mold can be put back into use for injection molding.
