[0002] The mold clamping device for high-speed engraving and milling machines is a key auxiliary functional component in the mold processing process of high-speed engraving and milling machines. Its core function is to accurately and firmly fix the mold to be processed (such as plastic mold, hardware mold, precision parts mold, etc.) on the worktable or processing reference surface of the engraving and milling machine, so as to prevent the mold from being displaced or shaking due to cutting force, centrifugal force or vibration during high-speed cutting, engraving and other processing, thereby ensuring processing accuracy, improving processing efficiency, and avoiding mold damage or equipment safety risks.

[0003] In the existing technology, the clamping device is fixedly installed on the high-speed engraving and milling machine, which is inconvenient to disassemble. The alignment space is limited when installing the mold, and it is difficult for the operator to place the mold accurately. This not only increases the difficulty of installation and operation, but may also require repeated adjustments due to alignment deviations, affecting the overall processing preparation efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a mold clamping device for a high-speed engraving and milling machine, so as to solve the problem mentioned in the background art that the clamping device is fixed on the high-speed engraving and milling machine, which is inconvenient to disassemble, resulting in insufficient alignment space during mold installation, making it difficult for operators to accurately place the mold, which not only increases the installation difficulty, but may also require repeated adjustments due to alignment deviation, thereby affecting the processing preparation efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold clamping device for a high-speed engraving and milling machine, comprising a movable block and a groove formed on the top of the movable block. A sliding groove is formed at the outer end of the groove, and a movable plate is slidably connected inside the sliding groove. A hook plate is connected to the top of the movable plate. A platform is movably connected to the top of the movable block, and a clamping assembly is provided on the top of the platform. Multiple springs are connected inside the groove and connected to the movable plate. Connecting columns are provided on the left and right sides of the rear end of the movable plate, and the connecting columns are staggered. A rotating plate is rotatably connected to the outer end of each connecting column. A turntable is rotatably connected to the rear end of the movable block, and a cylinder is connected to the rear end of the turntable. The rotating plate is rotatably connected to the turntable, and a circular plate is connected to the rear end of the cylinder. A handle is connected to the outer end of the circular plate. Rotating the handle drives the circular plate, which in turn drives the cylinder to rotate the turntable. The rotation of the turntable moves the rotating plate, and the movement of the rotating plate causes the connecting columns to compress the springs, thus releasing the hook plate from restricting the platform.

[0006] In the preferred embodiment of this technical solution, an adjustment groove is provided on the top of the platform, and a lead screw is rotatably connected inside the adjustment groove.

[0007] Based on the preferred embodiment of this technical solution, the outer end of the lead screw is threaded with a push plate, and the top front side of the platform is connected with a limit plate.

[0008] In this preferred embodiment of the technical solution, the rear end of the limiting plate is connected to an anti-slip plate, and the front end of the push plate is connected to the same anti-slip plate.

[0009] Based on the preferred embodiment of this technical solution, the rear end of the lead screw extends to the rear side of the platform and is connected to a knob, and anti-slip strips are connected to the left and right sides of the platform.

[0010] In a preferred embodiment of this technical solution, a threaded groove is provided on the lower inner side of the movable block, and sliders are connected to the left and right ends of the movable block.

[0011] Based on the preferred embodiment of this technical solution, the rotation of the knob drives the lead screw to rotate within the adjustment groove, and the rotation of the lead screw drives the push plate to cooperate with the limiting plate to clamp the mold.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By turning the handle, the transmission mechanism can release the hook plate from the platform, making it easy to adjust the platform position or remove the platform. This allows operators to place the mold in a more open space, significantly reducing the difficulty of alignment during mold installation and avoiding repeated adjustments due to space constraints. After releasing the handle, the spring automatically resets, causing the hook plate to re-clamp the platform, ensuring that the platform is stable and does not shift during processing. This lays the foundation for the subsequent clamping components to reliably hold the mold. The overall operation requires no complicated tools, which can reduce the manpower and time costs of mold installation and improve the operational efficiency of the processing preparation stage, adapting to the processing rhythm requirements of high-speed engraving and milling machines.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5This utility model provides an embodiment: a mold clamping device for a high-speed engraving and milling machine, including a movable block 1, and a groove 21 formed on the top of the movable block 1. A sliding groove 23 is formed at the outer end of the groove 21. A movable plate 22 is slidably connected inside the sliding groove 23. A hook plate 212 is connected to the top of the movable plate 22. A platform 24 is movably connected to the top of the movable block 1. A clamping assembly is provided on the top of the platform 24. Multiple springs 25 are connected inside the groove 21 and are connected to the movable plate 22. Connecting posts 26 are provided on the left and right sides of the rear end of the movable plate 22, and the connecting posts 26 are staggered. A rotating plate 27 is rotatably connected to the outer end of the connecting posts 26. A turntable 28 is rotatably connected to the rear end of the movable block 1. A cylinder 29 is connected to the rear end of the turntable 28. The rotating plate 27 and the turntable 28 rotate... The cylinder 29 is connected to a circular plate 210 at its rear end. The outer end of the circular plate 210 is connected to a handle 211. The handle 211 rotates to drive the circular plate 210, which in turn drives the cylinder 29 to rotate the turntable 28. The rotation of the turntable 28 drives the rotating plate 27 to move. The movement of the rotating plate 27 drives the connecting column 26 to cause the movable plate 22 to compress the spring 25, thus releasing the restriction of the hook plate 212 on the platform 24. By setting the sliding cooperation between the movable block 1, the groove 21 with the sliding groove 23 and the movable plate 22, combined with the limiting structure of the hook plate 212 and the platform 24, and the transmission mechanism composed of the spring 25, the staggered connecting column 26, the rotating plate 27, the turntable 28, the cylinder 29, the circular plate 210 and the handle 211, and supplemented by the clamping assembly on the top of the platform 24, a conveniently adjustable mold clamping system is constructed. Rotating the handle 211 will drive the movable plate 22 to compress the spring 25 through the transmission mechanism, quickly releasing the hook plate 212 from fixing the platform 24. This facilitates adjusting the position of the platform 24 or removing the platform 24, allowing operators to place the mold in a more open space. After releasing the handle 211, the spring 25 returns to its original position and pushes the movable plate 22, causing the hook plate 212 to re-clamp the platform 24, ensuring the stability of the platform 24. Subsequently, the mold can be reliably clamped by the clamping assembly, which reduces the difficulty of mold installation and improves the operational efficiency of the processing preparation stage.

[0017] Please see Figure 2-5 A further solution based on this embodiment is as follows: An adjustment groove 31 is provided on the top of the platform 24. A lead screw 32 is rotatably connected inside the adjustment groove 31. The adjustment groove 31 provides a stable installation and rotation space for the lead screw 32, avoiding the lead screw 32 from deviating and affecting the transmission accuracy. At the same time, it limits the rotation trajectory of the lead screw 32, ensuring that the subsequent push plate 35 moves in a precise direction, laying the foundation for the alignment accuracy of the mold clamping.

[0018] Please see Figure 1-5A further solution based on this embodiment is as follows: the outer end of the lead screw 32 is threadedly connected to a push plate 35, and the top front side of the platform 24 is connected to a limit plate 33. The lead screw 32 and the push plate 35 are threadedly engaged, which can convert the rotational motion of the lead screw 32 into the linear motion of the push plate 35, so as to realize the precise advance and retreat of the push plate 35. The limit plate 33 serves as the fixed reference end of the mold and forms a "push and stop" clamping structure with the push plate 35 to ensure that the mold can be stably clamped between the two.

[0019] Please see Figure 1-5 A further solution based on this embodiment is: the rear end of the limiting plate 33 is connected to the anti-slip plate 34, and the front end of the push plate 35 is connected to the same anti-slip plate 34. The anti-slip plate 34 can increase the friction with the contact surface of the mold, avoid the mold from being displaced due to the milling vibration after clamping, and at the same time buffer the direct squeezing of the clamping force on the mold surface, reducing the scratches or damage to the mold surface caused by clamping.

[0020] Please see Figure 1-5 A further solution based on this embodiment is as follows: the rear end of the lead screw 32 extends to the rear side of the platform 24 and is connected to a knob 36. Anti-slip strips 37 are connected to the left and right sides of the platform 24. The knob 36 provides the operator with a convenient force application component, which can rotate the lead screw 32 to adjust the position of the push plate 35 without the need for additional tools, thus reducing the difficulty of operation. The anti-slip strips 37 can enhance the friction between the operator's hand and the platform 24 when placing or adjusting the mold, so as to avoid the hand slipping and affect the safety of operation and the positioning accuracy of the mold.

[0021] Please see Figure 1-5 A further solution based on this embodiment is as follows: a threaded groove 38 is provided on the lower inner side of the movable block 1, and sliders 39 are connected to the left and right ends of the movable block 1. The threaded groove 38 facilitates the detachable connection between the movable block 1 and the corresponding parts of the engraving and milling machine table, thereby improving the overall installation flexibility of the device. The sliders 39 can cooperate with the slide rails of the engraving and milling machine table, so that the movable block 1 can slide smoothly, making it convenient to adjust the position of the entire device on the worktable and adapt to the processing requirements of molds of different sizes.

[0022] Please see Figure 1-5 A further solution based on this embodiment is as follows: the knob 36 rotates to drive the lead screw 32 to rotate in the adjustment groove 31. The rotation of the lead screw 32 drives the push plate 35 to cooperate with the limiting plate 33 to clamp the mold. This linkage structure realizes the integration of mold clamping operation. The operator only needs to rotate the knob 36 to control the push plate 35 to move forward and backward, quickly complete the clamping or loosening of the mold, simplify the operation process, reduce the mold installation and adjustment time, and improve the processing preparation efficiency.

[0023] Working principle: First, the device can be detachably connected to the corresponding part of the engraving and milling machine worktable through the threaded groove 38 on the lower side of the movable block 1. At the same time, the sliders 39 at both ends of the movable block 1 cooperate with the worktable slide rail. Pushing the movable block 1 can smoothly adjust its overall position on the worktable and quickly adapt to the size requirements of the mold to be processed. Next, if it is necessary to adjust the position of the platform 24 or remove the platform 24, the operator turns the handle 211. The handle 211 drives the circular plate 210 to rotate. The circular plate 210 drives the turntable 28 to rotate through the cylinder 29. When the turntable 28 rotates, it pulls the rotating plate 27. The rotating plate 27 drives the staggered connecting columns 26, so that the movable plate 22 slides along the slide groove 23 at the outer end of the groove 21 of the movable block 1 and squeezes the spring 25 in the groove 21, thereby releasing the hook plate 212 from the platform 2. After adjusting the limit 4, release handle 211. Spring 25 returns to its original position and pushes movable plate 22. Hook plate 212 re-clamps platform 24, ensuring the stability of platform 24 in subsequent processing. Finally, place the mold on platform 24 and rotate knob 36 connected to lead screw 32 on the rear side of platform 24. Lead screw 32 rotates in adjustment groove 31 on top of platform 24. Push plate 35, threaded at its outer end, moves linearly with lead screw 32. It works with limit plate 33 on the front side of top of platform 24 to form a "push and stop" clamping structure. During the process, anti-slip plate 34 at the rear end of limit plate 33 and front end of push plate 35 increases the friction with the mold contact surface, preventing mold displacement or surface damage due to milling vibration. Finally, reliable clamping of the mold is achieved, meeting the accuracy and stability requirements of high-speed milling.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
