Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, and in particular to a clamping fixture for metal mold processing. Background Technology

[0002] Clamping fixtures are used to precisely fix and position molds during the metal mold manufacturing process. They are essential tools in metal mold processing, and their main purpose is to ensure that the mold blank is accurately, stably, and safely fixed on the processing plane.

[0003] During the metal mold processing, the clamping fixture uses components such as clamping plates and reference blocks to stably fix the workpiece in a precise position corresponding to the processing equipment, thereby ensuring the accuracy of subsequent processing and avoiding dimensional deviations. However, during the process of fixing the metal mold with the clamping fixture, the worker may cause the clamping plate to excessively squeeze the workpiece in order to ensure the fixing effect. At this time, the excessive pressure on the clamping fixture may cause the thin-walled workpiece to be squeezed and deformed, or indentations to appear on the surface of the workpiece, which is not conducive to ensuring the accuracy of the final mold forming.

[0004] Therefore, this application provides a metal mold processing clamping fixture to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and to propose a metal mold processing clamping fixture.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a metal mold processing clamping fixture, comprising a clamping fixture body, and further comprising:

[0007] A clamping assembly is placed on top of a clamping fixture body. The clamping assembly includes sliding support blocks disposed on both sides of the top of the clamping fixture body. Side plates are connected to both sides of the clamping fixture body near the sliding support blocks. The sliding support blocks are slidably connected to the side plates. A clamping plate is disposed on the top of the sliding support blocks.

[0008] A limiting component is placed on top of the clamping component and used to limit the angle of the clamping plate. The limiting component includes a limiting plate connected to the top of the sliding support block near both sides of the clamping plate, and the clamping plate is engaged with the limiting plate.

[0009] Furthermore, one side of the sliding support block is threaded with a bolt.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the bolt pushes the side plate to the designated position through its own thread, and the bolt, through the self-locking property of the threaded connection, avoids the sliding support block from shifting and causing the mold to loosen, thereby improving the clamping stability.

[0011] Furthermore, an annular slider is connected to the bottom of the bolt, and an annular groove is provided on the side of the clamping fixture body near the annular slider. The bolt is rotatably connected to the clamping fixture body through the annular slider and the annular groove.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the annular slider and the annular groove cooperate to rotate the bolt to the clamping fixture body, thus preventing the bolt from falling out of the threaded hole of the sliding support block.

[0013] Furthermore, an anti-slip coating is provided on the side plate near the sliding support block.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the anti-slip coating, in conjunction with the bolts, resists the forces exerted on the sliding support block during processing, thereby further improving the stability of clamping.

[0015] Furthermore, a threaded post is provided between the clamping plate and the top of the clamping fixture body, the clamping plate and the threaded post are slidably connected, a nut is threadedly connected to the side of the threaded post near the clamping plate, and a pressure plate is provided between the nut and the clamping plate.

[0016] The beneficial effect of adopting the above-mentioned further solution is that: tightening the nut causes the nut to press against the clamping plate through the pressure plate, thereby clamping the workpiece and making it easier to quickly fix the workpiece.

[0017] Furthermore, a connecting block is connected to the side of the nut near the pressure plate, and a snap-fit ​​groove is provided on the side of the pressure plate near the nut. The nut is rotatably connected to the pressure plate through the connecting block and the snap-fit ​​groove.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the nut will not cause the pressure plate to rotate synchronously when it rotates, thus preventing excessive friction between the pressure plate and the clamping plate, which could lead to the pressure plate being unable to separate from the clamping plate, and ensuring that the pressure plate and nut can be removed stably.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] 1. This utility model, by setting up a clamping assembly, pushes the side plate upward so that its top reaches a preset position. When the clamping plate clamps the workpiece from the bottom, the side plate supports the clamping plate from below, thereby limiting the maximum downward movement of the clamping plate and preventing the operator from applying excessive clamping force. This avoids the problem of deformation or indentation of thin-walled workpieces due to excessive clamping force. At the same time, the side plate slides along the clamping plate and adjusts its own position according to the structure of the workpiece, thereby providing support for different types of workpieces and avoiding excessive clamping force, which helps to ensure the final forming accuracy of the mold.

[0021] 2. This utility model sets up a limiting component. By welding the limiting plate to the top of the sliding support block, when the clamping plate clamps the workpiece and moves closer to the inside of the limiting plate, the limiting plate limits the angle of the clamping plate from both sides, preventing the clamping plate from tilting or shifting due to force during processing. This ensures that the clamping plate always maintains the preset clamping state and also helps to ensure the stability of the clamping plate during use. Attached Figure Description

[0032] 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.

[0033] like Figures 1-5 As shown, this utility model provides a technical solution: a metal mold processing clamping fixture, including a clamping fixture body 1, and further comprising:

[0034] like Figures 1-2 As shown, clamping assembly 2 is placed on top of clamping fixture body 1. Clamping assembly 2 includes sliding support blocks 21 disposed on both sides of the top of clamping fixture body 1. Side plates 22 are connected to both sides of clamping fixture body 1 near the sliding support blocks 21. The sliding support blocks 21 are slidably connected to the side plates 22. A clamping plate 23 is disposed on the top of the sliding support blocks 21.

[0035] like Figures 1-2 As shown, the limiting component 3 is placed on top of the clamping component 2 and is used to limit the angle of the clamping plate 23. The limiting component 3 includes a limiting plate 31 connected to the top of the sliding support block 21 near both sides of the clamping plate 23. The clamping plate 23 is engaged with the limiting plate 31. By opening a slot on the side plate 22 that matches the clamping plate 23, the clamping plate 23 restricts the movement path of the side plate 22 through the slot, ensuring the stability of the side plate 22 during movement and preventing displacement. Pushing the side plate 22 upward, the top of the side plate 22 moves to a designated position. When the clamping plate 23 clamps the workpiece from the bottom, the side plate 22 supports the clamping plate 23 from the bottom, limiting the maximum downward movement distance of the clamping plate 23 and preventing the operator from applying excessive clamping force. This prevents deformation or indentation of thin-walled workpieces due to excessive clamping force. Simultaneously, since the side plate 22 can slide along the clamping plate 23, its position can be adjusted according to the workpiece's structure. This facilitates the side plate 22 supporting different workpieces, avoids excessive clamping force, and helps ensure the final forming accuracy of the mold. Furthermore, by welding the limiting plate 31 to the top of the sliding support block 21, when the clamping plate 23 clamps the workpiece and approaches the inner side of the limiting plate 31, the limiting plate 31 restricts the angle of the clamping plate 23 from both sides, preventing tilting and displacement of the clamping plate 23 during processing. This ensures that the clamping plate 23 is always in the preset clamping state, thus ensuring the stability of the clamping plate 23 during use.

[0036] Furthermore, such as Figure 2 As shown, a bolt 24 is threadedly connected to one side of the sliding support block 21. By installing the bolt 24 on the sliding support block 21, when the bolt 24 is rotated, the bolt 24 pushes the side plate 22 to the designated position through its own thread. When the bolt 24 stops rotating, the bolt 24 resists the force transmitted from the mold to the sliding support block 21 during the processing through the self-locking property of the threaded connection, thus preventing the sliding support block 21 from shifting and causing the mold to loosen, thereby improving the clamping stability.

[0037] Furthermore, such as Figure 2As shown, an annular slider 25 is connected to the bottom of the bolt 24. An annular groove 26 is provided on the side of the clamping fixture body 1 near the annular slider 25. The bolt 24 is rotatably connected to the clamping fixture body 1 through the annular slider 25 and the annular groove 26. By welding the annular slider 25 to the bottom of the bolt 24 and providing an annular groove 26 on the clamping fixture body 1 that matches the annular slider 25, the annular slider 25 and the annular groove 26 cooperate to rotatably connect the bolt 24 to the clamping fixture body 1, preventing the bolt 24 from falling out of the threaded hole of the sliding support block 21 and improving the safety and lifespan of the fixture.

[0038] Furthermore, such as Figure 3 As shown, an anti-slip coating 4 is provided on the side plate 22 near the sliding support block 21. By spraying the anti-slip coating 4 onto the side plate 22, the anti-slip coating 4 increases the friction between the side plate 22 and the sliding support block 21, so that the anti-slip coating 4 and the self-locking characteristics of the bolt 24 cooperate to resist the force on the sliding support block 21 during processing, preventing the sliding support block 21 from slipping off, thereby further improving the stability of clamping.

[0039] Furthermore, such as Figure 4 and Figure 5 As shown, a threaded post 27 is provided between the clamping plate 23 and the top of the clamping fixture body 1. The clamping plate 23 and the threaded post 27 are slidably connected. A nut 29 is threadedly connected to the side of the threaded post 27 near the clamping plate 23. A pressure plate 28 is provided between the nut 29 and the clamping plate 23. By fixing the bottom of the threaded post 27 to the top of the clamping fixture body 1, a sliding hole matching the outer diameter of the threaded post 27 is machined on the clamping plate 23. The clamping plate 23 is then fitted onto the threaded post 27, allowing the clamping plate 23 to slide along the axial direction of the threaded post 27. The nut 29 is screwed into the side of the threaded post 27 near the clamping plate 23, and the pressure plate 28 is placed between the nut 29 and the clamping plate 23. The nut 29 is tightened, and the nut 29 presses the clamping plate 23 through the pressure plate 28, causing the clamping plate 23 to clamp the workpiece, thereby facilitating the quick fixation of the workpiece.

[0040] Furthermore, such as Figure 4 and Figure 5 As shown, a connecting block 5 is connected to the side of the nut 29 near the pressure plate 28. A snap-fit ​​groove 6 is provided on the side of the pressure plate 28 near the nut 29. The nut 29 is rotatably connected to the pressure plate 28 through the connecting block 5 and the snap-fit ​​groove 6. By welding the connecting block 5 to the bottom of the nut 29, the connecting block 5 and the snap-fit ​​groove 6 are engaged, so that the nut 29 remains rotatably connected to the pressure plate 28 when it moves along the threaded post 27. This prevents the pressure plate 28 from rotating synchronously when the nut 29 rotates, thus preventing excessive friction between the pressure plate 28 and the clamping plate 23, which could cause the pressure plate 28 to be unable to separate from the clamping plate 23. This ensures that the pressure plate 28 and the nut 29 can be removed stably.

[0041] Working principle: such as Figures 1-5 As shown, the workpiece is first placed on the reference block of the clamping fixture body 1. An external hex wrench is used to rotate the bolt 24. The bolt 24 is rotatably connected to the clamping fixture body 1 through the engagement of the annular slider 25 and the annular groove 26, and its own threads push the sliding support block 21 upwards to the designated position. Then, the clamping plate 23 is fitted onto the threaded post 27, and the nut 29 is threaded onto the threaded post 27. Rotating the nut 29 causes it to move towards the clamping plate 23 via the threaded post 27. Since the pressure plate 28 is rotatably connected to the nut 29 through the connecting block 5 and the snap-fit ​​groove 6, the pressure plate 28 only moves in the direction of the nut 29. As the nut 29 moves along the axis, the pressure plate 28 pushes the clamping plate 23 to squeeze the workpiece, fixing the workpiece on the clamping fixture body 1. At this time, the clamping plate 23 is engaged with the inner side of the limiting plate 31. The limiting plate 31 limits the angle of the clamping plate 23 to prevent the clamping plate 23 from shifting during processing. The sliding support block 21 supports the clamping plate 23 from the bottom, limiting the maximum downward movement distance of the clamping plate 23 and preventing the thin-walled workpiece from deforming or developing indentations due to excessive clamping force. At the same time, the anti-slip coating 4 cooperates with the bolt 24 to resist the force exerted on the sliding support block 21 during processing and prevent the sliding support block 21 from slipping.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
