However, some fixture designs usually include multiple independent clamping blocks, and these clamping blocks achieve manual adjustment of the spacing through mechanical structures such as threaded rods, handles or levers. In the actual operation process, since multiple clamping blocks need to be adjusted repeatedly and each adjustment requires fine control, the entire adjustment process is not only cumbersome but also time-consuming, reducing the processing efficiency.

Detailed implementation manners

The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0021] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0022] An embodiment of the present utility model provides a fixture for mold processing, as Figures 1-5 shown. The fixture for mold processing includes: a base frame 1, on which a steerable fixture plate 2 is provided; a spacer block 3 fixed at the center position of the top of the fixture plate 2; symmetrically arranged clamping blocks 4 with adjustable spacing on the fixture plate 2; a screw rod 5 rotatably installed on the fixture plate 2, the screw rod 5 being used to adjust the spacing of the corresponding clamping blocks 4; a mounting block 6 threadedly sleeved on the screw rod 5, the top end of the mounting block 6 being fixedly connected to the bottom of the clamping block 4; a guide rod 7 slidably installed on the mounting block 6, both ends of the guide rod 7 being fixedly connected to the fixture plate 2; a first motor 8 assembled on the fixture plate 2, the output shaft of the first motor 8 being fixedly connected to the corresponding screw rod 5 through a coupling; and an adjustment mechanism arranged on the base frame 1 for regulating the steering of the fixture plate 2.

[0023] It should be noted that the original design intention of the fixture for traditional mold processing is mainly to ensure that the mold can be stably clamped and accurately positioned during the processing to guarantee the processing accuracy and product quality. However, this design often pays too much attention to the basic clamping force and positioning accuracy, while ignoring the importance of operation convenience and adjustment efficiency. The process of manually adjusting the distance between the clamping blocks usually involves the following steps: First, the fixing device of the clamping block (such as a nut or a locking screw) needs to be loosened; Second, the clamping block is moved to the required position by rotating the threaded rod, the handle or operating the lever; Finally, the clamping block is fixed again to ensure its stability. During this process, since the position of each clamping block needs to be precisely controlled, the worker needs to repeatedly adjust and confirm many times, which is not only cumbersome in operation but also time-consuming. During the mold processing, every time the mold is replaced or the size is adjusted, the distance between the clamping blocks needs to be adjusted again. If the adjustment process is cumbersome and time-consuming, it will directly lead to the extension of the processing cycle and the reduction of the processing efficiency. Therefore, a new type of fixture for mold processing is needed to solve the above problems;

[0024] In this embodiment, the base frame 1 serves as the basic support structure of the entire fixture. The base frame 1 ensures the stability and durability of the fixture. Its design should take into account the load-bearing capacity and stability to cope with various forces and vibrations during the mold processing; The steerable function provided on the fixture plate 2 enables the fixture to flexibly adapt to the mold processing requirements in different directions. This design increases the versatility and flexibility of the fixture. The spacer block 3 fixed at the center of the top of the fixture plate 2 is used to provide a stable support surface to ensure the smoothness of the mold during the processing. At the same time, the material and shape of the spacer block 3 can be selected and designed according to specific requirements to achieve the best support effect. The clamping blocks 4 with adjustable distance are symmetrically arranged on the fixture plate 2. The quick adjustment of the distance is realized through the linkage of the screw rod 5, the mounting block 6 and the guide rod 7. This design abandons the traditional manual adjustment method and greatly improves the adjustment efficiency. The screw rod 5 is rotatably installed on the fixture plate 2, and its rotation is driven by the first motor 8 (connected through a coupling), thereby driving the mounting block 6 to move along the axial direction of the screw rod 5. The top end of the mounting block 6 is fixedly connected to the bottom of the clamping block 4. Therefore, the rotation of the screw rod 5 will directly result in the change of the distance between the clamping blocks 4. This electric drive method is not only labor-saving but also has higher precision. The guide rod 7 is slidably installed on the mounting block 6. The guide rod 7 ensures the stability and linearity of the mounting block 6 during the movement. The two ends of the guide rod 7 are fixedly connected to the fixture plate 2, forming a stable guiding system, effectively preventing the mounting block 6 from offsetting or shaking during the movement. Through the drive of the first motor 8 and the mechanical linkage mechanism, the quick and precise adjustment of the distance between the clamping blocks 4 is realized, avoiding the cumbersome and time-consuming traditional manual adjustment method. The worker only needs to perform a simple operation to complete the adjustment of the distance between the clamping blocks 4, greatly reducing the labor intensity.

[0025] In a further preferred embodiment of the present utility model, the adjusting mechanism includes: a steering shaft 9 rotatably mounted on the base frame 1, the top end of the steering shaft 9 being fixedly connected to the bottom of the fixture plate 2; a transmission shaft 10 rotatably mounted on the base frame 1; a second motor 11 assembled on the base frame 1, the output shaft of the second motor 11 being fixedly connected to the transmission shaft 10 through a coupling; a first bevel gear 12 fixed on the transmission shaft 10 for transmission; and a second bevel gear 13 fixed at the bottom end of the steering shaft 9, the second bevel gear 13 meshing with the first bevel gear 12.

[0026] In this embodiment, the design of the adjusting mechanism further improves the functionality of the fixture for mold processing. Through electric drive, precise steering adjustment of the fixture plate 2 is achieved, further enhancing the operation convenience and processing efficiency. The steering shaft 9 is rotatably mounted on the base frame 1, and its top end is fixedly connected to the bottom of the fixture plate 2. This design enables the rotation of the steering shaft 9 to directly drive the fixture plate 2 to turn, thereby realizing the adjustment of the mold processing direction. The transmission shaft 10 is also rotatably mounted on the base frame 1 and serves as an intermediate link for power transmission. Its position and direction design need to match the steering requirements of the steering shaft 9 to ensure smooth and accurate power transmission. The second motor 11 is assembled on the base frame 1, and its output shaft is fixedly connected to the transmission shaft 10 through a coupling. This design enables the second motor 11 to serve as a power source to drive the transmission shaft 10 to rotate, thereby driving the entire adjusting mechanism to work. The first bevel gear 12 is fixed on the transmission shaft 10 for transmission, and its design enables the rotation of the transmission shaft 10 to be converted into a rotational force perpendicular to the direction of the transmission shaft 10. This design is the key to realizing the steering function. The second bevel gear 13 is fixed at the bottom end of the steering shaft 9 and meshes with the first bevel gear 12. When the first bevel gear 12 rotates, through the meshing action between the gears, the rotational force is transmitted to the second bevel gear 13, thereby driving the steering shaft 9 and the fixture plate 2 to turn. By driving the transmission shaft 10 to rotate with the second motor 11 and using the meshing action of the bevel gears, precise steering adjustment of the fixture plate 2 is achieved. This method is not only easy to operate but also has high steering accuracy, capable of meeting the fine adjustment requirements during the mold processing process.

[0027] In a further preferred embodiment of the present utility model, assembly plates 14 are symmetrically and fixedly installed at the bottom of the base frame 1. Corresponding assembly holes are provided in the assembly plates 14, and bolts for limiting are arranged in the assembly holes.

[0028] In this embodiment, the bottom design of the base frame 1 is optimized. By adding the assembly plate 14 and the assembly holes and limit bolts thereon, the overall more stable installation and fixation of the fixture are achieved. The assembly plates 14 are symmetrically and fixedly installed at the bottom of the base frame 1. These assembly plates 14 are used to connect the base frame 1 and the processing table. Corresponding assembly holes are provided on the assembly plates 14. These assembly holes are used to receive and fix the limit bolts to ensure that the fixture can maintain a stable position after installation.

[0029] In a further preferred embodiment of the present utility model, a rubber block 15 is provided on one surface of the clamping block 4. A number of convex blocks for anti-slip are provided on the rubber block 15. A first assembly frame is fixedly installed on the fixture plate 2. A first support is provided on the first assembly frame. The first support is fixedly connected to the first motor 8.

[0030] In this embodiment, by adding the rubber block 15 and its anti-slip convex blocks on the clamping block 4, the rubber material has good elasticity and wear resistance, which can effectively buffer the direct contact between the mold and the clamping block 4 and reduce the damage to the mold surface. A number of convex blocks for anti-slip are provided on the rubber block 15. These convex blocks can further increase the contact area and friction force between the rubber block 15 and the mold, preventing the mold material from slipping or falling off due to vibration or external force during the processing.

[0031] In a further preferred embodiment of the present utility model, a number of through slots 16 are symmetrically provided on the fixture plate 2. The through slots 16 are adapted to the screw rod 5, the guide rod 7 and the mounting block 6.

[0032] In this embodiment, the design of the fixture plate 2 is optimized. By symmetrically providing a number of through slots 16 thereon and adapting them to the screw rod 5, the guide rod 7 and the mounting block 6, this means that these components can be smoothly installed and positioned through the through slots 16.

[0033] In a further preferred embodiment of the present utility model, a second assembly frame is fixedly installed on the base frame 1. A second support is provided on the second assembly frame. The second support is fixedly connected to the second motor 11.

[0034] In this embodiment, the second motor 11 is fixed by adding the second assembly frame and the second support thereon to the base frame 1. This design ensures that the second motor 11 can maintain a stable posture and position during operation, avoiding affecting its driving effect and transmission accuracy due to vibration or loosening.

[0035] In a further preferred embodiment of the present utility model, a threaded hole and a sliding hole are provided on the mounting block 6. The threaded hole is adapted to the screw rod 5, and the sliding hole is adapted to the guide rod 7.

[0036] In this embodiment, the design of the mounting block 6 is refined. By providing threaded holes and sliding holes on it, which are respectively adapted to the screw rod 5 and the guide rod 7, this design further enhances the adjustment accuracy and stability of the fixture. This design ensures that when the screw rod 5 rotates for adjustment, the mounting block 6 can move smoothly along the direction of the guide rod 7, improving the accuracy and stability of the adjustment.

[0037] In summary, by adding the rubber block 15 and its anti-slip protrusions to the clamping block 4, the friction during the clamping process is increased, preventing the mold material from slipping or falling off. By adopting the method of driving the screw rod 5 to rotate by the first motor 8, rapid and precise adjustment of the distance between the clamping blocks 4 is achieved, abandoning the cumbersome and time-consuming traditional manual adjustment method, and greatly improving the adjustment efficiency and accuracy. The steerable function design on the fixture plate 2 enables the fixture to flexibly adapt to the mold processing requirements in different directions.
