Description

Technical Field

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

[0002] Positioning and clamping devices are equipment that use mechanical structures to precisely fix the position of workpieces and prevent them from shifting during processing. They are characterized by high positioning accuracy and stable clamping. Their core function is to ensure the positional accuracy of workpieces during processing. They are suitable for various precision manufacturing scenarios and are closely related to mold inserts. Mold inserts are detachable precision components in molds. During installation, they need to be precisely aligned with the mold body. Positioning and clamping devices are the key to ensuring the installation accuracy of inserts.

[0003] In existing mold insert positioning and clamping devices, the positioning pins and positioning surfaces are precisely aligned with the positioning holes and reference surfaces of the inserts to determine the unique position of the inserts in the mold and prevent displacement. Then, the driving components such as cylinders, hydraulic cylinders, or manual screws are activated to move the grippers or pressure plates toward the inserts, applying clamping force from the side or top to initially fix the inserts. Finally, the clamping components are reinforced by locking structures such as locking nuts and positioning bolts to prevent the clamping force from loosening due to vibration during processing, ensuring that the inserts always maintain a stable posture.

[0004] In practical use, the insufficient positioning accuracy of some mold insert positioning and clamping devices can cause dimensional deviations. The device cannot adaptively compensate for the error, which can lead to the offset of the insert installation position. Ultimately, this can cause problems such as out-of-tolerance dimensions and uneven wall thickness in the parts produced by the mold. Uneven force can cause damage or deformation to the insert. Non-adaptive clamping may lead to excessive local pressure, causing micro-deformation or surface scratches on the insert, which can affect the appearance of the parts and may also shorten the service life of the insert.

[0005] Therefore, it is necessary to provide a new mold insert positioning and clamping device to solve the above-mentioned technical problems. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0021] Please see Figures 1 to 4A mold insert positioning and clamping device includes a base 1. The core function of the base 1 is to provide a stable foundation support for the entire device. Utilizing the high stability and weight advantage of cast iron, it resists vibration or external impact during device operation and prevents the device from shifting as a whole. A placement platform 2 is fixedly connected to the top of the base 1. The main function of the placement platform 2 is to support the mold insert and the self-adaptive installation mechanism. Its flat surface ensures that the insert remains horizontal after placement, avoiding clamping offset due to platform tilt. Self-adaptive installation mechanisms are fixedly connected to the left and right sides inside the placement platform 2. A fixing plate 8 is fixedly connected to the outside of the self-adaptive installation mechanism. The main function of the fixing plate 8 is to directly contact the mold insert and provide clamping force. The anti-slip rubber pad can increase the friction with the insert, prevent the insert from sliding during clamping, and avoid direct metal contact that scratches the surface of the insert. Disassembly and assembly mechanisms are slidably connected to the front and rear sides outside the fixing plate 8. The adaptive mounting mechanism includes a mounting frame 3. The core function of the mounting frame 3 is to provide a stable mounting carrier for components such as the fixed shaft 4 and the rotating plate 5, accommodating the rotational movement of the rotating plate 5. The mounting frame 3 is externally fixedly connected to the left and right sides of the placement platform 2. The fixed shaft 4 is internally fixedly connected to the mounting frame 3. The main function of the fixed shaft 4 is to provide a rotation fulcrum for the rotating plate 5, allowing the rotating plate 5 to rotate flexibly around the fixed shaft 4. At the same time, the bearing design reduces rotational friction, ensuring smooth and uninterrupted adjustment of the rotating plate 5. The rotating plate 5 is externally rotatably connected to the fixed shaft 4. The core function of the rotating plate 5 is to transmit clamping force and achieve angle adjustment: when the fixed frame 6 slides with the damping slider 7, the rotating plate 5 can rotate around the fixed shaft 4. The angle between the rotating plate 5 and the placement platform 2 is adjusted to adapt to the clamping requirements of inserts of different thicknesses. The other end of the rotating plate 5 is rotatably connected to the fixing frame 6. The main function of the fixing frame 6 is to connect the rotating plate 5 and the damping slider 7, converting the rotational motion of the rotating plate 5 into the linear sliding of the damping slider 7, providing a stable clamping surface, and ensuring that the insert is subjected to uniform force during clamping. The damping slider 7 is fixedly connected to the outside of the fixing frame 6. The core function of the damping slider 7 is to realize the sliding connection between the fixing plate 8 and the fixing frame 6. Its wear-resistant coating can reduce sliding friction and extend service life. At the same time, the damping properties enable the slider to maintain a stable position after sliding, avoiding slider displacement due to vibration, and ensuring clamping accuracy. The external sliding connection of the damping slider 7 is inside the fixing plate 8. A reset assembly is provided on the outside of the fixed plate 8. The reset assembly includes a slide groove 9. The main function of the slide groove 9 is to provide installation space for the fixed rod 10 and the reset spring 11, and to guide the sliding of subsequent components, restricting the movement direction of the components and preventing displacement during the reset process. The slide groove 9 is located on the outside of the fixed plate 8, and the fixed rod 10 is fixedly connected inside the slide groove 9. The core function of the fixed rod 10 is to provide a mounting carrier for the reset spring 11, restrict the extension and contraction direction of the spring, prevent the spring from twisting and deforming under force, and ensure that the spring can stably provide elastic force in a fixed direction. A reset spring 11 is sleeved on the outside of the fixed rod 10. The main function of the reset spring 11 is to provide reset force. When the adaptive mounting mechanism adjusts the position to clamp the insert, the spring is compressed and stores elastic potential energy. When the insert is released, the spring releases the potential energy and pushes the mechanism to automatically reset to the initial position. No manual adjustment is required, which improves the operating efficiency. A mounting plate 12 is installed on the outside of the fixed plate 8. The core function of the mounting plate 12 is to close the slide groove 9 to prevent external dust and impurities from entering the slide groove 9 and affecting the operation of the reset component. At the same time, it also protects the reset spring 11 and the fixed rod 10.

[0022] The disassembly and assembly mechanism includes a sliding latch 13. The core function of the sliding latch 13 is as the active component of the disassembly and assembly mechanism. By sliding axially along the sliding hole, it drives the subsequent connecting frame 14 and rotating plate 15 to move, thereby controlling the extension and retraction of the positioning latch 17 to achieve locking or unlocking actions. Its smooth surface reduces sliding friction, ensuring smooth operation. The sliding latch 13 is externally slidably connected to the front and rear sides of the fixed plate 8. The fixed plate 8 has an internal cavity 18. The main function of the cavity 18 is to provide concealed installation and movement space for the sliding latch 13 and the connecting frame 14, preventing these components from being exposed to dust contamination or external impact damage. Simultaneously, the enclosed space restricts the direction of component movement, preventing radial offset of the sliding latch 13 during sliding and ensuring transmission accuracy. The external fixed connection of the sliding latch 13 is... The core function of the connecting frame 14 is to connect the sliding rod 13 and the rotating plate 15, converting the linear sliding of the sliding rod 13 into the rotational motion of the rotating plate 15. The rotating plate 15 is rotatably connected to the outside of the connecting frame 14. The main function of the rotating plate 15 is to realize the conversion of the motion direction: when the connecting frame 14 slides with the sliding rod 13, the rotating plate 15 rotates around the two end pins, converting the axial motion of the sliding rod 13 into the lateral motion of the connecting frame 16, providing power for the extension and retraction of the positioning rod 17. The other end of the rotating plate 15 is rotatably connected to the connecting frame 16. The core function of the connecting frame 16 is to connect the rotating plate 15 and the positioning rod 17, converting the rotational motion of the rotating plate 15 into the linear extension and retraction motion of the positioning rod 17. At the same time, the cooperation of the guide groove can limit the motion direction of the connecting frame 16. The connecting bracket 16 is externally fixedly connected to a positioning rod 17. The core function of the positioning rod 17 is to achieve a locking function. When it is necessary to install accessories, the positioning rod 17 extends out of the fixing plate 8 and embeds into the preset slot of the accessory, preventing the accessory from falling off through the end structure. When disassembling, the positioning rod 17 retracts, releasing the engagement with the slot, and completing the disassembly of the accessory. Its high-strength end structure can ensure that it can withstand a certain external force after locking, preventing the accessory from loosening. The fixing plate 8 is internally equipped with an elastic component, which includes a telescopic rod 19. The main function of the telescopic rod 19 is to provide an installation carrier and guide for the spring 20, limit the extension and retraction direction of the spring, prevent the spring from twisting and deforming under force, and at the same time, through its own extension and retraction... The movement of the positioning lever 17 is coordinated to ensure that the positioning lever 17 always moves along the axial direction, improving the locking accuracy. The telescopic rod 19 is externally fixed to the inside of the fixed plate 8. The telescopic rod 19 is sleeved with a mounting spring 20. The core function of the mounting spring 20 is to provide elastic force: on the one hand, by continuously pushing the connecting frame 16, the positioning lever 17 is kept in the extended state, ensuring that the parts are automatically locked after installation without manual maintenance. On the other hand, when disassembling the parts, the operator pushes the sliding lever 13 to compress the mounting spring 20 to store elastic potential energy. After releasing the sliding lever 13, the spring releases the potential energy to drive the connecting frame 16 and the positioning lever 17 to reset, realizing automatic extension and improving the convenience of operation.

[0023] The positioning lever 17 is externally slidably connected to the inside of the cavity 18. The outside of the positioning lever 17 is locked to the outside of the mounting plate 12. The two sliding levers 13 are fixedly connected to the outside of the handles 21. The core function of the handles 21 is to provide the operator with a convenient point of force application. Originally, the two sliding levers 13 needed to be pushed separately, but they can be pushed simultaneously through the handles 21, reducing the number of operation steps. The anti-slip rubber sleeve can increase the friction between the hand and the handles 21 to prevent slippage during operation. The outside of the handles 21 fits against the outside of the fixing plate 8. The mold insert placement rack is fixedly connected to the top of the outside of the placement platform 2. 22. The main function of the mold insert placement rack 22 is to provide a precise placement and positioning reference for the mold insert: the grid structure can adapt to inserts of different sizes, and the initial positioning can be achieved by adjusting the position of the insert in the grid; the multi-station groove design can provide a dedicated placement position for inserts of specific shapes, avoiding the insert from shifting during placement. The damping slider 7 is internally slidably connected to the outside of the fixing rod 10, the fixing bracket 6 is externally slidably connected to the outside of the fixing rod 10, one end of the return spring 11 is fixedly connected to the outside of the damping slider 7, and the other end of the return spring 11 is fixedly connected to the outside of the slide groove 9.

[0024] The working principle of the mold insert positioning and clamping device provided by this utility model is as follows: First, by placing the mold insert inside the base 1, the mold insert can press against the mounting plate 12, which in turn presses against the damping slider 7 via the fixing plate 8. This allows the damping slider 7 to slide inside the groove 9. As the damping slider 7 slides, it presses against the return spring 11 outside the fixing rod 10, causing the return spring 11 to deform. This causes the rotating plate 5 outside the damping slider 7 to rotate, and the reaction force of the return spring 11 allows the mounting plate 12 to be installed. This enables the mounting plate 12 to adaptively install mold inserts of different sizes. When assembling or disassembling the mounting plate 12, pulling the handle 21 causes the sliding lever 13 to slide inside the fixed plate 8. This sliding lever 13, via the connecting bracket 14, causes the rotating plate 15 to rotate. Under the action of the rotating plate 15, the positioning lever 17 slides inside the cavity 18 via the connecting bracket 16. This allows the positioning lever 17 to press against the telescopic rod 19, thereby enabling the telescopic rod to... The external mounting spring 20 of the telescopic rod 19 deforms, thereby separating the positioning lever 17 from the mounting plate 12, allowing the mounting plate 12 to be removed and disassembled. At this point, the mounting plate 12 is in contact with the fixing plate 8. Then, by releasing the handle 21, the external mounting spring 20 of the telescopic rod 19 rebounds, and under the action of the mounting spring 20, the positioning lever 17 is locked to the outside of the mounting plate 12, thereby enabling the installation of the mounting plate 12.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
