[0002] Large mold frame closing mechanisms are suitable for industrial production scenarios that require precise and efficient mold closing operations, especially in molding processes such as injection molding, die casting, and stamping. They can ensure accurate mold alignment and stable pressing, thereby improving production efficiency and product quality.
[0003] However, existing technologies still have the following problems:
[0004] In the prior art, the mold closing mechanism is prone to problems such as insufficient stability and inaccurate displacement control during the movement process. In the past, the movement of the mold closing position often relied on simple mechanical transmission or hydraulic drive. These methods are prone to unstable movement and inaccurate displacement control due to friction, wear or fluctuations in the hydraulic system, which in turn affects the accuracy and efficiency of the mold closing operation.

[0016] 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.
[0017] Example: Figure 1-3As shown, this utility model provides a large mold frame closing mechanism. The closing platform 1 serves as the supporting foundation of the entire mechanism, and a support frame 4 is fixedly connected to its upper end. A moving mechanism 2 is fixedly provided on the upper inner wall of the support frame 4. The moving mechanism 2 includes a moving frame 20, which is fixedly connected to the support frame 4. A motor 21 is installed on one side of the moving frame 20, and its output end is fixedly connected to a threaded rod 25. A moving plate 23 is threadedly fitted onto the outer surface of the threaded rod 25. Two limiting plates 27 are fixedly provided at the lower end of the moving frame 20. Each of the two limiting plates 27 has a limiting groove 28 on one side that cooperates with two limiting blocks 29. The moving plate 23 cooperates with the limiting groove 28 on the moving frame 20 through the limiting blocks 29 to ensure its stability during movement. At the same time, the moving plate 23 also slides against the moving rod 26 through the moving groove 24 to further enhance its smoothness of movement. The lower end of the moving mechanism 2 is fixedly connected to a pressing mechanism 3.
[0018] Mounting bracket 22 provides a solid support for motor 21, ensuring the stability of motor 21 when driving threaded rod 25 to rotate. The cooperation between moving groove 24 and moving rod 26, as well as the cooperation between limiting block 29 and limiting groove 28, further enhances the stability and accuracy of moving plate 23 during movement, thereby improving the operating efficiency of the entire mold closing mechanism.
[0019] The pressing mechanism 3 is based on the pressing frame 30, the upper end of which is fixedly connected to the lower end of the moving plate 23. Below the pressing frame 30, two cylinders 32 are fixedly connected to the pressing frame 30 through the fixing frame 31. The output end of the cylinders 32 is fixedly provided with a moving inclined plate 37. The inclined surfaces of the two moving inclined plates 37 and the sliding inclined plate 33 cooperate with each other. The lower end of the sliding inclined plate 33 is fixedly provided with a pressing plate 34. In addition, the lower end of the pressing frame 30 is also fixedly provided with a reset rod 39. The lower end of the reset rod 39 is connected to a reset plate 36 that cooperates with the sliding inclined plate 33. The upper end of the reset plate 36 is fixedly provided with a reset spring 38.
[0020] The fixed frame 31 provides a stable mounting position for the cylinder 32, ensuring the stability of the cylinder 32 when driving the moving inclined plate 37. The inclined surfaces of the moving inclined plate 37 and the sliding inclined plate 33 cooperate to allow the pressing plate 34 to rise and fall smoothly, thereby achieving precise pressing of the mold. The coordinated use of the reset rod 39, the reset plate 36 and the reset spring 38 ensures that the pressing plate 34 can quickly reset after completing the pressing action, preparing for the next pressing action.
[0021] Working principle: When the mold needs to be positioned and closed, the motor 21 is started through the moving mechanism 2. Its output end drives the threaded rod 25 to rotate. Since the moving plate 23 is threadedly sleeved with the threaded rod 25, and is limited by the cooperation of the limiting block 29 and the limiting groove 28 and the sliding contact of the moving groove 24 and the moving rod 26, the moving plate 23 will slide smoothly along the moving rod 26 under the rotation of the threaded rod 25. In this way, the moving mechanism 2 can drive the pressing mold mechanism 3 to perform precise displacement control.
[0022] When the mold needs to be closed via the pressing mechanism 3, the moving mechanism 2 drives the pressing frame 30 to descend to a certain position, and the cylinder 32 starts to work. Its output end pushes the moving inclined plate 37 to move towards the middle. Since the inclined surfaces of the moving inclined plate 37 and the sliding inclined plate 33 are engaged, the sliding inclined plate 33 will move downward, driving the pressing plate 34 to press the mold. When the pressing action is completed, the cylinder 32 retracts, and the moving inclined plate 37 moves back to its original position. At this time, the return spring 38, through the action of the return plate 36 and the return rod 39, pushes the sliding inclined plate 33 and the pressing plate 34 to quickly return to their original positions. During the return process, the sliding inclined plate 33 slides in the return groove 35, ensuring the stability and accuracy of the return.
[0023] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
