Description

Technical Field

[0001] This utility model relates to the field of mold base technology, and in particular to a combined mold base. Background Technology

[0002] A modular mold base is a device used in mold manufacturing and processing to support, position, and secure molds. Its modular design allows it to adapt to molds of different sizes and shapes, ensuring stability, precision, and reliability during processing. This type of base typically consists of multiple detachable and combinable components, facilitating installation, adjustment, and maintenance, and is widely used in various mold manufacturing fields.

[0003] In existing mold processing, traditional fixed mold bases are typically used. These bases require manual adjustment of the mold's position, using bolts or other fixing devices to secure the mold to the base. Operators need to adjust the mold's position one by one according to its size and shape to ensure stability during processing. While this type of base meets basic mold fixing requirements, in practice, operators need to spend considerable time and effort manually adjusting it to ensure precise mold positioning.

[0004] The existing method of manually adjusting mold positions has several limitations. Since each mold needs to be manually positioned and fixed, this not only increases the complexity and time cost of the operation but is also prone to inaccurate positioning due to human factors. Such inaccurate positioning can affect the precision and quality of mold processing, thereby reducing production efficiency. Furthermore, traditional fixed mold bases lack flexibility in adapting to molds of different sizes and shapes, making it difficult to quickly adjust to meet diverse needs. Therefore, a modular mold base is proposed to address these issues. Utility Model Content

Through the telescopic action of electric telescopic rod 503, rack 504 can be driven to slide in strip groove 501, thereby driving driven gear 505 to rotate, thereby achieving precise control of rotating rod 506 and ensuring rapid positioning and clamping of mold.

[0030] Reference Figure 4 The top of the rotating rod 506 penetrates the bottom of the support base 2 and is fixedly connected to the turntable 508. The outer surface of the turntable 508 contacts the inner wall of the support base 2. An arc-shaped hole 509 is opened on the top surface of the turntable 508. A sliding rod 5010 is slidably connected to the inner wall of the arc-shaped hole 509. A moving block 3 is fixedly connected to the top of the sliding rod 5010.

[0032] According to Figure 5 , Figure 6 The movable block 3 is equipped with a self-locking structure 6, which includes a threaded rod 602. The inner wall of the movable block 3 has a movable groove 601. The top of the movable block 3 is threadedly connected to the threaded rod 602. The bottom end of the threaded rod 602 is rotatably connected to the extrusion block 604 through a bearing.

The bottom of the extrusion block 604 is respectively engaged with the two inclined blocks 605. The side of the two inclined blocks 605 that is far apart from each other has a serration A. The side of the strip block 403 that is adjacent to each other has a serration B. The serration A and the serration B are engaged. By rotating the threaded rod 602, the extrusion block 604 can be pushed downward, thereby causing the inclined blocks 605 to move away from each other, so that the serration A and the serration B are engaged, thereby achieving reliable locking of the position of the movable block 3, preventing the mold from shifting during processing, and improving the accuracy and reliability of mold processing.

[0033] Reference Figure 7The self-locking structure 6 also includes a slider 606, the top of which is fixedly connected to the bottom of the inclined block 605. The bottom of the inner wall of the movable groove 601 is provided with a sliding groove 607, and the slider 606 is slidably connected to the inner wall of the sliding groove 607. The side of the slider 606 is elastically connected to the inner wall of the sliding groove 607 through a spring B608. One end of the spring B608 is fixedly connected to the inner wall of the movable groove 601, and the other end of the spring B608 is fixedly connected to the side of the slider 606. A knob 603 is fixedly connected to the top of the threaded rod 602. Two symmetrical inclined surfaces are provided on both sides of the bottom of the extrusion block 604. The two symmetrical inclined surfaces at the bottom of the extrusion block 604 abut against the inclined surfaces of the two inclined blocks 605 respectively. Through the elastic action of the spring B608, the inclined block 605 can be quickly reset when unlocked. At the same time, the design of the knob 603 allows the operator to easily and quickly perform locking and unlocking operations, further improving the practicality and ease of operation of the mold base.

[0034] Working principle: First, the mold is placed on the base 1. According to the size of the mold, the extension end of the electric telescopic rod 503 pushes the rack 504 to slide in the strip groove 501. The rack 504 meshes with the driven gear 505, driving the rotating rod 506 to rotate in the circular groove 502. The turntable 508 at the top of the rotating rod 506 rotates accordingly, and the sliding rod 5010 slides in the arc-shaped hole 509, thereby driving the moving block 3 at the top of the movable rod 402 to move, so that the clamping plate 401 on the moving block 3 can adapt to molds of different sizes. When the clamping plate 401 contacts the mold, the spring A404 provides a certain elastic force, so that the clamping plate 401 can tightly clamp the mold, realizing the fixation of the mold. Next, by rotating the knob 603 in the self-locking structure 6, the threaded rod 602 rotates, causing the extrusion block 604 to move downwards. Its bottom inclined surface abuts against the inclined surface of the inclined block 605, pushing the inclined blocks 605 away from each other. The serration A on the inclined block 605 engages with the serration B on the strip block 403. Simultaneously, the slider 606 slides within the groove 607. The spring B608 provides a certain elastic force, allowing the inclined block 605 to stably engage with the serration B, thereby locking the position of the moving block 3 and ensuring that the mold does not shift during processing. When it is necessary to change the mold or adjust its position, the knob 603 is rotated in the opposite direction, causing the threaded rod 602 to rotate in the opposite direction. The extrusion block 604 moves upwards, and the inclined blocks 605 move closer together under the action of the spring B608. The serration A and serration B separate, releasing the lock on the moving block 3. Then, the position of the moving block 3 is adjusted using the electric telescopic rod 503. Repeating the above steps allows for mold replacement or position adjustment.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
