Description

Technical Field

[0001] This utility model belongs to the technical field of graphite mold clamping devices, and particularly relates to a clamping device for graphite mold processing. Background Technology

[0002] In recent years, the mold industry has developed rapidly, and graphite materials, with their excellent physical and chemical properties, have gradually become the preferred material for mold making, laying the foundation for the widespread application of graphite molds. In the current graphite mold processing, the lower mold is often fixed to a pre-drilled worktable with bolts. However, this method of installing molds by fixing and disassembling with bolts is time-consuming and not very practical. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a clamping device for graphite mold processing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A clamping device for processing graphite molds includes a base, and the base is square.

[0006] The base has first clamping blocks symmetrically slidably slidably provided at both ends of the top, and a second sliding groove is provided through the middle of the first clamping block, with second clamping blocks slidably provided at both ends of the second sliding groove;

[0007] The base has a first groove at the center line, and a gear and a rack are provided in the first groove. The gear is rotatably located at the middle of the bottom of the first groove, and two racks are located on both sides of the gear and mesh with the gear. The racks are slidably connected to the first groove.

[0008] The first groove is equipped with an electric telescopic rod, and the output end of the electric telescopic rod is connected to the end of one of the racks;

[0009] The bottom of the first clamping block is fixed with a first slider, and the two first clamping blocks are respectively fixedly connected to the top of the corresponding rack through the first slider.

[0010] Through the above technical solution, the two first clamping blocks can move relative to each other under the meshing action of gears and racks to clamp the two sides of the mold body. The two second clamping blocks on the first clamping blocks can clamp the other two sides of the mold body, thereby clamping all four sides of the mold body and improving the stability of the mold body.

[0011] Furthermore, a third slide groove is provided on opposite sides inside the first slide groove, and a second slider is fixed on the side of the rack away from the gear. The second slider and the third slide groove are convex, and the second slider is slidably disposed inside the third slide groove.

[0012] Through the above technical solution, the third groove plays a limiting role in the sliding of the rack, thereby improving the stability of the rack sliding.

[0013] Furthermore, a baffle is fixed at the end of the rack away from the first clamping block to prevent the rack from moving too far and disengaging from the gear.

[0014] Furthermore, a first moving block is slidably provided at both ends of the second groove. The first moving block is located on the opposite side of the two second clamping blocks, and a spring is fixedly connected between the first moving block and the second clamping block.

[0015] A connecting rod is rotatably provided on one side of the first movable block, and a connecting block is provided at the other end of the connecting rod, and the connecting rod and the connecting block are rotatably connected;

[0016] An adjusting plate is fixedly provided on one side of the two first clamping plates facing away from each other, and a threaded rod is rotatably provided inside the adjusting plate;

[0017] The lower end of the connecting block extends into the interior of the adjusting plate and is slidably connected to the adjusting plate. The threaded rod passes through the lower end of the connecting block and is threadedly connected to the connecting block.

[0018] Through the above technical solution, by rotating the threaded rod, the connecting block is moved, thereby driving the first moving block to move along the second sliding groove through the connecting rod, and thus the second clamping block moves with the first moving block.

[0019] Furthermore, the spring is provided with a telescopic column inside, and the two ends of the telescopic column are fixedly connected to the sides of the second clamping block and the first moving block, respectively. The telescopic column is a damping telescopic column, which can buffer the elastic force of the spring and prevent the second clamping block from reciprocating due to the spring action during the movement.

[0020] Furthermore, a fourth slide groove is provided on both the upper and lower sides of the second slide groove, and square protrusions are provided on the upper and lower sides of the second clamping block and the first moving block, and the square protrusions correspond to the fourth slide grooves. The first clamping block and the first moving block are slidably connected to the fourth slide grooves through the square protrusions.

[0021] Through the above technical solution, the fourth slide groove assists the sliding of the second clamping block and the first moving block, and will not detach from the second slide groove.

[0022] Furthermore, the top of the adjusting plate is provided with a rotating groove, the threaded rod is rotatably disposed in the rotating groove, and one end of the threaded rod extends out of the rotating groove and is provided with a rotating knob;

[0023] The lower end of the connecting block is T-shaped and slidably disposed within the rotating groove.

[0024] With the above technical solution, the connecting block slides in the rotating groove, driving the connecting rods on both sides to move.

[0025] Furthermore, the end of the second clamping block furthest from the first clamping block is arc-shaped, which allows the mold body to enter between the two second clamping blocks from both sides more effectively.

[0026] This utility model has the following beneficial effects:

[0027] This invention uses an electric telescopic rod to move one rack, which in turn moves the other rack through gear meshing. This, in turn, causes the first clamping block to move relative to the first rack, clamping and fixing both sides of the mold body. By rotating the threaded rod, the connecting block moves, which in turn moves the connecting rods on both sides, thereby moving the first moving block and the second clamping block to clamp the other two sides of the mold body. By using the first and second clamping blocks to clamp the four sides of the mold body, the stability of the mold body during processing and use can be ensured. Attached Figure Description

[0042] like Figures 1-5As shown, a clamping device for graphite mold processing includes a base 1, which is square. First clamping blocks 3 are symmetrically slidably arranged at both ends of the top of the base 1. A second sliding groove 32 is formed through the middle of the first clamping blocks 3. Second clamping blocks 4 are slidably arranged at both ends of the second sliding groove 32. First moving blocks 41 are slidably arranged at both ends within the second sliding groove 32. The first moving blocks 41 are located on opposite sides of the two second clamping blocks 4. A spring 42 is fixedly connected between the first moving blocks 41 and the second clamping blocks 4. A telescopic column 45 is provided inside the spring 42. The telescopic column 45 is a damping telescopic column 45, and its two ends are fixedly connected to the sides of the second clamping blocks 4 and the first moving blocks 41, respectively. A connecting rod 43 is rotatably arranged on one side of the first moving block 41, and a connecting block 44 is provided at the other end of the connecting rod 43. The connecting rod 43 and the connecting block 44 are rotatably connected. An adjusting plate 33 is fixedly provided on one side opposite to a clamping plate. A threaded rod 34 is rotatably provided inside the adjusting plate 33. The lower end of a connecting block 44 extends into the adjusting plate 33 and is slidably connected to the adjusting plate 33. The threaded rod 34 passes through the lower end of the connecting block 44 and is threadedly connected to the connecting block 44. A first sliding groove 11 is provided at the center line of the base 1. A gear 2 and a rack 21 are provided in the first sliding groove 11. The gear 2 is rotatably located at the middle of the bottom of the first sliding groove 11. Two racks 21 are located on both sides of the gear 2 and are meshed with the gear 2. The racks 21 are slidably connected to the first sliding groove 11. An electric telescopic rod 22 is provided in the first sliding groove 11. The output end of the electric telescopic rod 22 is connected to the end of one of the racks 21. A first slider 31 is fixedly provided at the bottom of the first clamping block 3. The two first clamping blocks 3 are respectively fixedly connected to the top of the corresponding racks 21 through the first slider 31.

[0043] In use, the mold body 9 is placed on the base 1. The electric telescopic rod 22 drives one of the racks 21 to move, and through the meshing of the gear 2, it drives the other rack 21 to move. The movement of the two racks 21 drives the first clamping block 3 connected to them to move relative to each other, clamping both sides of the mold body 9. Then, the threaded rod 34 is rotated, which drives the connecting block 44 to move along the axis of the threaded rod 34 under the action of the thread. This drives the connecting rods 43 on both sides of the connecting block 44 to move, so that the first moving block 41 on the other side of the connecting rod 43 drives the second clamping plate to move in the second slide groove 32. The spring 42 is compressed and exerts pressure on the second clamping plate. Each of the two first clamping plates is provided with a pair of second clamping blocks 4, which can clamp both ends of one side of the mold body 9 adjacent to the first clamping plate, improving the stability of clamping.

[0044] Specifically, a third slide groove 12 is provided on opposite sides inside the first slide groove 11. A second slider 23 is fixed on the side of the rack 21 away from the gear 2. The second slider 23 and the third slide groove 12 are convex and the second slider 23 is slidably disposed inside the third slide groove 12, which limits the sliding direction of the rack 21. A baffle 24 is fixed on the end of the rack 21 away from the first clamping block 3 to prevent the rack 21 from moving too far and disengaging from the gear 2.

[0045] Specifically, the top of the adjusting plate 33 is provided with a rotating groove 36, the threaded rod 34 is rotatably disposed in the rotating groove 36, one end of the threaded rod 34 extends out of the rotating groove 36 and is provided with a rotating knob; the lower end of the connecting block 44 is T-shaped and is slidably disposed in the rotating groove 36.

[0046] Specifically, the second slide groove 32 has a fourth slide groove 35 on both the upper and lower sides. The upper and lower sides of the second clamping block 4 and the first moving block 41 are square protrusions, and the square protrusions correspond to the fourth slide groove 35. The first clamping block 3 and the first moving block 41 are slidably connected to the fourth slide groove 35 through the square protrusions. The end of the second clamping block 4 away from the first clamping block 3 is arc-shaped, which can better allow the mold body 9 to enter between the two second clamping blocks 4 from both sides. When clamping mold bodies 9 of the same size, there is no need to repeatedly adjust the distance between the two second clamping blocks 4. When the two first clamping blocks 3 are close together, the mold body 9 can enter between the two second clamping blocks 4 from the arc-shaped side of the two second clamping blocks 4, and the second clamping block 4 compresses the spring 42 to better clamp the mold body 9.

[0047] The working principle of this utility model is as follows: When in use, the mold body 9 is placed on the base 1. The electric telescopic rod 22 drives one of the racks 21 to move, and through the meshing action of the gear 2, it drives the other rack 21 to move. The movement of the two racks 21 drives the first clamping block 3 connected to them to move relative to each other, clamping both sides of the mold body 9. Then, the threaded rod 34 is rotated, which drives the connecting block 44 to move along the axis of the threaded rod 34 under the action of the thread, thereby driving the connecting rods 43 on both sides of the connecting block 44 to move. This causes the first moving block 41 on the other side of the connecting rod 43 to drive the second clamping plate to move in the second slide groove 32. After the spring 42 is compressed, it exerts pressure on the second clamping plate. Each of the two first clamping plates is provided with a pair of second clamping blocks 4, which can clamp both ends of one side of the mold body 9 adjacent to the first clamping plate, thus improving the stability of the clamping.

[0048] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
