DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1-4, the utility model provides a technical solution:

[0025] A tungsten-molybdenum mold clamp includes a base 1. An adaptor 2 is provided on the top of the base 1 for adapting to tungsten-molybdenum molds of different sizes for clamping. The adaptor 2 includes:

[0026] The clamping unit 21 is provided on the top of the base 1 and is used to pass the clamping power;

[0027] The adjusting unit 22 is arranged above the clamping unit 21 and includes a mounting box 221. An I-shaped slot 222 is provided inside the mounting box 221. A first rack 224 is slidably installed inside the lower transverse slot of the I-shaped slot 222, and a second rack 225 is slidably installed inside the upper transverse slot of the I-shaped slot 222. A rotating column 226 is rotatably installed inside the mounting box 221, and a gear 227 is fixedly installed on the outside of the rotating column 226. The gear 227 is meshed with the first rack 224 and the second rack 225. A handwheel 223 is fixedly installed on one end of the rotating column 226. The outer ends of the first rack 224 and the second rack 225 are both provided with a clamping seat assembly 4 and are installed in a bilaterally symmetrical manner. The inner ends of the first rack 224 and the second rack 225 are both provided with a thrust assembly 3.

[0028] The limiting unit 23 is provided on one side of the mounting box 221 and is used to limit the rotation of the rotating column 226 and the gear 227 .

[0029] The hand wheel 223 rotates to drive the gear 227 to rotate through the rotating column 226, and the gear 227 drives the first rack 224 and the second rack 225 to move toward or in the opposite direction, thereby driving the clamping seat assembly 4 to move toward or in the opposite direction synchronously, thereby clamping and fixing tungsten-molybdenum molds of different specifications and sizes.

[0030] In this embodiment, the thrust assembly 3 includes two fixed blocks 31 fixedly installed on the left and right sides of the mounting box 221. A plug 32 is fixedly installed at one end of the fixed block 31, and the plug 32 is movably inserted into the interior of the first rack 224 and the second rack 225. A thrust spring 33 is mounted on the outside of the plug 32.

[0031] When the gear 227 stops rotating, the thrust spring 33 pushes the second rack 225 and the first rack 224 by its own elastic force, thereby preventing the first rack 224 and the second rack 225 from moving toward each other when the second rack 225 and the first rack 224 are not moving.

[0032] In this embodiment, the clamping seat assembly 4 includes two connecting blocks 41 fixedly mounted on the outer ends of the first rack 224 and the second rack 225, a right-angle plate 42 is fixedly mounted on one side of the connecting block 41, and a right-angle rubber pad 43 is fixedly mounted inside the right-angle plate 42, and a circular groove 44 is provided at the right angle of the right-angle rubber pad 43.

[0033] A horizontal bar is provided on the inner side of the circular groove 44 so as to increase the vertical friction force on the tungsten-molybdenum mold and prevent the tungsten-molybdenum mold from moving up and down.

[0034] In this embodiment, the clamping unit 21 includes a base 211 fixedly mounted on the top of the base 1, a bidirectional screw rod 212 is rotatably mounted inside the base 211, a motor 213 is fixedly mounted on the right side of the base 211, and the right end of the bidirectional screw rod 212 is fixedly connected to the output end of the motor 213, two moving blocks 214 are mounted on the external thread of the bidirectional screw rod 212, and a clamping plate 215 is fixedly mounted on the top of the moving block 214, a rubber pad 216 is fixedly mounted on the inner side of the clamping plate 215, and the mounting box 221 is fixedly mounted on the outer side of the clamping plate 215.

[0035] The motor 213 is a three-phase asynchronous motor with a self-locking function. It is electrically connected to an external power supply and is opened and closed by a person operating the control panel. The operation of the motor 213 drives the bidirectional screw 212 to rotate, thereby driving the two clamping plates 215, the rubber pad 216, the adjustment unit 22 and the limit unit 23 to move toward each other to clamp the tungsten-molybdenum mold.

[0036] In this embodiment, the limiting unit 23 includes a ratchet 231 fixedly installed on the outside of the rotating column 226, a fixing plate 232 is fixedly installed on one side of the mounting box 221, a fixing shaft 235 is fixedly installed on one side of the fixing plate 232, a pawl 236 is rotatably installed on the outside of the fixed shaft 235, and one end of the pawl 236 is engaged with the ratchet 231, a fixing seat 233 is fixedly installed on one side of the fixing plate 232, a pressure spring 234 is fixedly installed on the bottom of the fixing seat 233, and the bottom end of the pressure spring 234 is fixedly connected to the pawl 236.

[0037] When the rotating column 226 and the gear 227 rotate clockwise, the first rack 224 and the second rack 225 are driven to move toward each other. At this time, the ratchet 231 rotates synchronously. When the gear 227 stops rotating, the pressure spring 234 pushes the pawl 236 to rotate through its own elastic force, so that the pawl 236 engages with the ratchet 231, preventing the gear 227 from rotating in the opposite direction when the clamping seat assembly 4 clamps the tungsten-molybdenum mold.

[0038] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0039] During operation, first, the hand wheel 223 is rotated to rotate the gear 227 through the rotating column 226, and the gear 227 drives the first rack 224 and the second rack 225 to move toward or in the opposite direction, thereby driving the clamping seat assembly 4 to move toward or in the opposite direction synchronously, and adjusting the clamping seat assembly 4 to a clamping position suitable for the tungsten-molybdenum mold to be processed. When the rotating column 226 and the gear 227 rotate clockwise, the first rack 224 and the second rack 225 are driven to move toward each other. At this time, the ratchet 231 rotates synchronously. When the gear 227 stops rotating, the pressure spring 234 pushes the pawl 236 to rotate through its own elastic force, so that the pawl 236 is engaged with the ratchet 231. When the rotating column 226 and the gear 227 rotate counterclockwise, one end of the pawl 236 needs to be pressed down, and the ratchet 231 is in contact and meshing state;

[0040] Then, the motor 213 is operated to drive the bidirectional screw rod 212 to rotate, thereby driving the two clamping plates 215 and the rubber pad 216 to move toward each other to clamp the tungsten-molybdenum mold.
