A T-shaped fixed clamp 5 is fixedly installed on the top of the two moving blocks 4, and a pair of movable side clamps 6 are installed on the upper parts of the opposite sides of the two T-shaped fixed clamps 5. A side clamp adjustment structure 7 is installed between one end of the two n-shaped grooves 2, and the side clamp adjustment structure 7 is transmission-connected to the two pairs of side clamps 6. An adjustment mechanism 8 is installed in the middle of one end of the device base 1, and the adjustment mechanism 8 is transmission-connected to the side clamp adjustment structure 7 and one of the threaded shafts 3. An engagement and separation adjustment mechanism 9 connected to the adjustment mechanism 8 is installed in the lower part of one end of the device base 1. A lifting and lowering adjustment structure 10 is installed in the middle of the top of the device base 1, and a placing table 11 is installed on the top of the lifting and lowering adjustment structure 10.

[0030] The side clamp adjustment structure 7 includes a cylindrical gear 12, which is rotatably connected between one end of the two n-shaped grooves 2. One end of the bottom of the two moving blocks 4 is rotatably connected to a transmission bevel gear 13. The two transmission bevel gears 13 are symmetrically arranged. The ends of the two transmission bevel gears 13 that are opposite to each other in axis are fixedly connected to a transmission gear 14. The two transmission gears 14 are meshed with the cylindrical gear 12. A transmission shaft 15 is rotatably connected between the moving block 4 and the inside of the T-shaped fixed clamp plate 5. The bottoms of the two transmission shafts 15 are fixedly connected to transmission bevel gears 16. The two transmission bevel gears 16 are respectively meshed with the two transmission bevel gears 13.

[0031] An inverted N-shaped groove 17 is provided on the upper part of the opposite sides of the two T-shaped fixed clamps 5, and the inside of the two inverted N-shaped grooves 17 is rotatably connected with a bidirectional threaded shaft A18, and the two pairs of side clamps 6 are respectively threadedly connected to the two sides of the two bidirectional threaded shafts A18, and one end of the two bidirectional threaded shafts A18 is fixedly installed with a rotating bevel gear 19, and the tops of the two transmission shafts 15 extend to the inside of the two inverted N-shaped grooves 17 and are fixedly connected with a rotating bevel gear 20, which is meshed with the rotating bevel gear 19. The middle parts of the two inverted N-shaped grooves 17 are rotatably installed with resistance rollers 21 at equal distances, and the surfaces of the resistance rollers 21 are provided with a rubber layer for clamping and anti-slip, so that the die-casting mold can be effectively clamped and fixed.

[0032] The die-casting mold is placed on the top of the placement table 11, and then the two moving blocks 4 are moved relative to each other through the synchronous rotation of the two threaded shafts 3. The two moving blocks 4 that move relative to each other drive the two T-shaped fixed clamping plates 5 to move relative to each other. The two T-shaped fixed clamping plates 5 that move relative to each other drive the abutting rollers 21 and the rubber layer thereon to abut and clamp the two sides of the die-casting mold.

[0033] At the same time, the relatively moving moving block 4 drives the two transmission gears 14 to move relatively, and the two relatively moving transmission gears 14 slide on the surface of the cylindrical gear 12 and maintain meshing connection;

[0034] After the interference rollers 21 on the two T-shaped fixed clamps 5 are used to clamp and fix the two sides of the die-casting mold through the rubber layer, the two transmission gears 14 are driven to rotate through the rotation of the cylindrical gear 12. The rotation of the two transmission gears 14 will drive the two transmission bevel gears 13 to rotate and respectively rotate the two transmission shafts 15. The rotation of the two transmission shafts 15 will drive the two rotating bevel gears 20 to rotate. The rotation of the two rotating bevel gears 20 will respectively transmit the two rotating bevel gears 19 and drive the two bidirectional threaded shafts A18 to rotate. The rotation of the bidirectional threaded shaft A18 will cause the two side clamps 6 on its surface to move relative to each other, and finally the relatively moving side clamps 6 will contact the two ends of the die-casting mold and squeeze the die-casting mold, so that the die-casting mold is moved by the rolling of the interference rollers 21, thereby clamping and fixing the die-casting mold and performing centering adjustment.

[0035] The clamping device has the functions of bidirectional synchronous movement and independent adjustment of clamping and fixing on the X-axis and Y-axis. The bidirectional synchronous movement and independent adjustment of clamping and fixing on the X-axis and Y-axis can clamp and fix die-casting molds of different sizes. The clamping device has a lifting and adjusting function so that die-casting molds of different sizes can be stably and effectively clamped and fixed, thereby effectively improving the performance and scope of use of the clamping device.

[0036] Embodiment 2, on the basis of embodiment 1, the adjustment mechanism 8 includes a transmission box 22, the transmission box 22 has a worm 23 rotatably connected inside, one end of the worm 23 extends to the outside of one end of the transmission box 22 and is fixedly connected to a first rotating wheel 24, one end of the top of the transmission box 22 is rotatably connected to a worm wheel A25 meshing with the worm 23, an adjusting bevel gear A26 located on the upper surface of the transmission box 22 is fixedly connected at the axis center of the worm wheel A25, one end of a threaded shaft 3 extends to the outside of one end of the device base 1 and is fixedly connected to an adjusting bevel gear B27 meshing with the adjusting bevel gear A26.

[0037] One end of the bottom of the transmission box 22 is rotatably connected to a worm wheel B28 that meshes with the worm 23. The axis of the worm wheel B28 is fixedly connected to an adjusting bevel gear C29 located at the lower part of the surface of the transmission box 22. One end of the cylindrical gear 12 extends to the outside of one end of the device base 1 and is fixedly connected to an adjusting bevel gear D30 that matches the adjusting bevel gear C29, so that the T-shaped fixed clamp plate 5 and the side clamp plate 6 can be adjusted separately in turn.

[0038] The worm 23 is rotated by the first rotating wheel 24 to rotate the worm wheel A25 and the worm wheel B28. The rotation of the worm wheel A25 and the worm wheel B28 will drive the adjusting bevel gear A26 and the adjusting bevel gear C29 to rotate. The rotation of the adjusting bevel gear A26 will transmit the adjusting bevel gear B27 to rotate one of the threaded shafts 3. The rotation of one of the threaded shafts 3 will drive the other threaded shaft 3 to rotate synchronously to move the two moving blocks 4.

Both sides of the two-way threaded shaft B33 are threadedly connected with adjustment blocks 34 slidably mounted inside the adjustment groove 32. The tops of the two adjustment blocks 34 are rotatably connected to the bottom of the transmission box 22 with adjustment rods 35, one end of the two-way threaded shaft B33 extends to the outside of one end of the fixed block 31 and is fixedly connected to a second rotating wheel 36, two pairs of sleeve plates 38 are fixedly mounted on one side of the transmission box 22, and two inverted N-shaped slide bars 37 are symmetrically fixedly mounted in the middle of one end of the device base 1. The two pairs of sleeve plates 38 are respectively slidably sleeved on the surfaces of the two inverted N-shaped slide bars 37, so that effective adjustment can be performed.

[0040] After the two T-shaped fixing clamps 5 are clamped and fixed to the die-casting mold by the contact roller 21 and the rubber layer, the bidirectional threaded shaft B33 is rotated by the second rotating wheel 36, and the rotation of the bidirectional threaded shaft B33 causes the two adjusting blocks 34 to move in opposite directions, and the two adjusting blocks 34 moving in opposite directions drive the transmission box 22 to move downward through the two adjusting rods 35, and the downwardly moving transmission box 22 can stably move downward on the surface of the inverted N-shaped slide bar 37 through the sleeve plate 38, and the downwardly moving transmission box 22 drives the adjusting bevel gear A26 to move downward and separate from the adjusting bevel gear B27, and at the same time, the downwardly moving transmission box 22 drives the adjusting bevel gear C29 to move downward and mesh with the adjusting bevel gear D30;

[0041] Then the same operation is performed to rotate the worm 23 through the first rotating wheel 24, and finally the adjusting bevel gear C29 transmits the adjusting bevel gear D30 to drive the cylindrical gear 12 to rotate. The rotation of the cylindrical gear 12 causes the four side clamps 6 to squeeze and move the die-casting mold and adjust the center of the die-casting mold.

[0042] Embodiment 3, on the basis of embodiment 1, the lifting adjustment structure 10 includes a fixed frame 40 fixedly installed in the middle of the top of the device base 1, an n-shaped plate 41 is arranged inside the fixed frame 40, and both ends of the n-shaped plate 41 are installed with a ball 1 in contact with the inside of the fixed frame 40, so that the n-shaped plate 41 can be easily moved and adjusted, the placement table 11 is fixedly installed on the top of the n-shaped plate 41, and the top of the placement table 11 is equidistantly installed with a ball 2 42, and the upper part of both sides of the inside of the fixed frame 40 is provided with a wheel groove 43, and the n-shaped An oblique through groove 44 is provided in the middle of both sides of the plate 41, and an adjusting pin 45 is installed between the two oblique through grooves 44 and the inside of the two wheel grooves 43. The adjusting pin 45 is located inside the two wheel grooves 43 and an adjusting wheel 46 is installed therein. A telescopic rod 47 located inside the n-shaped plate 41 is installed at one end inside the fixed frame 40, and the telescopic end of the telescopic rod 47 is connected to the middle of the adjusting pin 45, so that the height of the placement table 11 can be adjusted so that the die-casting mold can be effectively located between the two T-shaped fixed clamps 5 and the four side clamps 6.

[0043] The die-casting mold is placed on the top of the placement table 11 and can be effectively moved and adjusted through the ball 2 42. Then, the adjustment pin 45 is pulled to move by the contraction of the telescopic rod 47. The movement of the adjustment pin 45 can be stably moved horizontally through the rolling of the adjustment wheel 46. The horizontally moving adjustment pin 45 can effectively adjust the n-shaped plate 41 upward through the two oblique through grooves 44. The upward movement of the n-shaped plate 41 will drive the placement table 11 to move upward, and the upward movement of the placement table 11 will drive the die-casting mold to move upward, so that the die-casting mold can be effectively located between the two T-shaped fixing clamps 5 and the four side clamps 6, and can be effectively clamped, fixed and centered.
