Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically to a quick clamping device for molds used in the molding of copper-nickel composite materials. Background Technology

[0002] In the field of copper-nickel composite material molding and processing, the mold, as the core tooling, directly affects the production cycle and molding quality of composite material components due to its clamping efficiency and stability. Copper-nickel composite materials, which combine the high thermal conductivity and electrical conductivity of copper with the corrosion resistance and high strength of nickel, are widely used in key industries such as electronics, chemicals, and aerospace. The molding process places strict requirements on the positioning accuracy, clamping reliability, and ease of operation of the mold.

[0003] However, existing traditional methods generally employ multiple bolts, pressure plates, and other parts for manual fastening. When loading and unloading molds, workers need to use tools to tighten and loosen a large number of bolts one by one, which is time-consuming and labor-intensive, making "quick" clamping and releasing impossible. This severely impacts production rhythm and mold change efficiency. Therefore, those skilled in the art provide a quick clamping device for molds used in copper-nickel composite material molding to solve the problems mentioned in the background art. Summary of the Invention

[0016] 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.

[0017] Please see Figures 1-3 As shown, this utility model provides a technical solution: a quick clamping device for molds used in the molding of copper-nickel composite materials, including a bearing structure 1 for supporting the upper component, a clamping structure 2 for clamping inside the bearing structure 1, and locking structures 3 for adapting to different molds at both ends of the top of the bearing structure 1. The clamping structure 2 includes two horizontal plates 25, a cylinder 26, and two support rods 27. The two support rods 27 are slidably connected to the two ends inside the two horizontal plates 25. One horizontal plate 25 is rotatably connected to the two ends of a first connecting rod 21. One end of the two first connecting rods 21 is rotatably connected to a pull rod 22. One end of the two pull rods 22 is rotatably connected to a second connecting rod 24. The two second connecting rods 24 are rotatably connected to the two ends of the other horizontal plate 25. One horizontal plate 25 is fixedly connected to the output end of the cylinder 26. Multiple clamping rods 23 are fixedly connected to the top of both horizontal plates 25.

[0018] The core of the clamping structure 2 is a symmetrical linkage mechanism driven by a cylinder 26. When the piston rod of the cylinder 26 extends or retracts, it drives the horizontal plate 25 connected to it to move. Then, through the linkage system composed of the first link 21, the pull rod 22 and the second link 24, the power is transmitted to another horizontal plate 25. Under the precise guidance and constraint of the two support rods 27, the two horizontal plates 25 convert the unidirectional driving force of the cylinder into stable and synchronous opposite or back-to-back movements.

[0019] As one implementation method in this embodiment, please refer to Figure 1 and Figure 5 As shown, the locking structure 3 includes a frame 31, a pin 35 is slidably connected inside the frame 31, a slider 36 is slidably connected to the bottom of the frame 31, a spring 34 is fixedly connected to the top of the slider 36, one end of the spring 34 is fixedly connected to the top of the inner wall of the frame 31, an extension plate 32 is fixedly connected to the top of the frame 31, a limit rod 33 is slidably connected inside the extension plate 32, the limit rod 33 is inserted into the pin 35, and the spring 34 is sleeved on the outside of the pin 35.

[0020] The locking structure 3 achieves rapid locking and unlocking through the cooperation of the pin 35 and the spring 34. When the pin 35 is pressed down, it overcomes the elastic force of the spring 34 and inserts into the limiting hole 14. When the hole on the pin 35 is aligned with the limiting rod 33, the restoring force of the spring 34 pushes the slider 36 and the pin 35 back slightly, allowing the limiting rod 33 to smoothly insert into the hole of the pin 35, thus mechanically preventing the pin 35 from coming out. When unlocking, simply pull out the limiting rod 33, and the spring 34 will push the pin 35 out of the limiting hole 14. Compared with traditional bolt fastening, this saves a lot of time and significantly improves mold changing efficiency. The spring-assisted restoring mechanism ensures smooth operation and automatic alignment, while the limiting rod provides a purely mechanical locking mechanism that is safe and reliable.

[0021] As one implementation method in this embodiment, please refer to Figures 1-5 As shown, the load-bearing structure 1 includes a support frame 11, four support legs 12 are fixedly connected to the bottom of the support frame 11, a support plate 13 is fixedly connected to the top of the support frame 11, a plurality of grooves 16 are provided on the top of the support plate 13, a mold 15 is provided on the top of the support plate 13, and limit holes 14 are provided at both ends of the top of the support plate 13.

[0022] The supporting structure 1 serves as the base of the entire device, providing a stable platform and reference for clamping and locking operations. The support plate 13 directly supports the mold 15, and the groove 16 on it provides a precise guide channel for the vertical movement of the clamping rod 23. The limiting hole 14 cooperates with the pin 35 of the locking structure 3 to form the horizontal positioning coordinate system of the mold. The integral supporting structure ensures the rigidity and stability of the device, providing solid support for the molding process. The pre-set groove 16 and limiting hole 14 on the support plate 13 have clear functional divisions, ensuring the accuracy of all movements.

[0023] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, two horizontal plates 25 are slidably connected to the bottom of the inner wall of the support frame 11, and two support rods 27 are fixedly connected to both ends of the inner wall of the support frame 11.

[0024] The dual-guide design significantly improves the rigidity and motion accuracy of the moving parts, which is key to ensuring that all clamping rods 23 can be raised and lowered synchronously and smoothly. It effectively disperses the lateral forces that may be generated by the linkage mechanism, extends the service life of the cylinder and the linkage hinge point, and makes the entire clamping process more stable and reliable.

[0025] As one implementation method in this embodiment, please refer to Figures 1-2 and Figure 5 As shown, multiple clamping rods 23 are slidably connected inside multiple grooves 16, pins 35 are inserted into limiting holes 14, and upright frames 31 are fixedly connected to both sides of mold 15.

[0026] This implementation clearly defines the interaction between the three core structures. The cooperation between the clamping rod 23 and the groove 16 transforms the horizontal movement of the horizontal plate 25 into the oblique movement path of the clamping rod. The cooperation between the pin 35 and the limiting hole 14 establishes the unique correct position of the mold on the support plate 13 before the clamping action begins. The upright frame 31, fixed to both sides of the mold 15, is key to giving the locking function to the mold itself. These connections together achieve the ideal workflow of "precise positioning first, then uniform clamping." It ensures the repeatability of each clamping and makes the mold positioning independent of the operator's experience, reducing the difficulty of operation and providing a structural foundation for achieving fast, high-quality standardized operations. As one implementation method in this embodiment, please refer to Figure 5 As shown, a pull plate 37 is fixedly connected to one end of the pin 35.

[0027] The design of the pull plate 37 makes it easier and less strenuous to pull out the pin when manual assistance is required, such as when the spring fails or more force is needed, thus improving the user experience. It also prevents the pin 35 from falling completely into the frame 31, making it a detail design that combines functionality and safety.

[0028] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the mold 15 is located between multiple clamping rods 23.

[0029] This clamping method from both sides at the bottom provides a very stable clamping effect, while avoiding the need for a complex pressure plate mechanism at the top. This makes it easier to lift and place the mold, and it is especially suitable for molding scenarios that require material filling or process operations from above, ensuring the mold is double-fixed in both the vertical and horizontal directions.

[0030] Working principle: The piston rod of cylinder 26 extends, pushing the connected horizontal plate 25 to move to the right. The connecting rod moves, and this horizontal plate 25 pulls the pull rod 22 through the first connecting rod 21 at both ends. Mechanism deformation: After the pull rod 22 is pulled, it will drive the second connecting rod 24, forcing the other horizontal plate 25 to move in the same direction. However, since the two horizontal plates 25 are limited by the support rod 27, they actually move closer to each other. Execution action: The two horizontal plates 25 move closer to each other, causing all the clamping rods 23 fixed on their tops to slide upward along the groove 16 of the support plate 13, completing the clamping. The upward-moving clamping rods 23 clamp the mold upward and inward from both sides of the bottom of the mold 15, providing stable clamping force in the vertical and horizontal directions.

[0031] Place the mold 15 on the support plate 13, and roughly align the upright frames 31 on both sides of the mold with the limiting holes 14 on the support plate. Press down on the pin 35 to insert it into the limiting hole 14. At this time, the pin 35 will compress the spring 34. When the hole on the pin 35 is aligned with the limiting rod 33, the slider 36 will push upward under the restoring force of the spring 34, causing the pin 35 to spring back slightly, allowing the limiting rod 33 to automatically engage in the hole of the pin 35, thereby preventing the pin 35 from coming out and completing the lateral positioning of the mold.

[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
