[0020] Embodiment: As Figure 1-7As shown in the figure, the utility model provides a positioning device for mold processing, including a processing table 1. A first clamping component 4 and a second clamping component 5 are arranged on the lower surface of the processing table 1. The first clamping component 4 includes a first motor 41. The output shaft of the first motor 41 is fixedly connected with a bevel gear 42. A bidirectional threaded rod 43 is fixedly arranged outside the bevel gear 42. A first groove 12 distributed in an array is opened on the upper surface of the processing table 1. Two first clamping blocks 46 are slidably arranged inside two of the first grooves 12. The two ends of the bidirectional threaded rod 43 threadedly penetrate through the opposite sides of the two first clamping blocks 46. Fixed blocks 45 symmetrically distributed are fixedly arranged on the lower surface of the processing table 1. The two ends of the bidirectional threaded rod 43 are respectively rotatably connected with the opposite sides of the fixed blocks 45. One end of the bidirectional threaded rod 43 rotatably penetrates through the outside of one of the fixed blocks 45. The second clamping component 5 includes a second motor 51. The lower end of the second motor 51 is fixedly connected with the upper surface of the bottom plate 2. The output shaft of the second motor 51 is fixedly connected with a first gear 52. A second clamping block 56 is slidably arranged inside the first groove 12 far away from the first clamping block 46. Tooth plates 53 are fixedly arranged on the opposite sides of the two second clamping blocks 56. The opposite sides of the two tooth plates 53 are meshed with the outside of the first gear 52. By arranging the first clamping component 4 and the second clamping component 5, clamping of the mold is realized from four directions. By controlling the rotation of the first motor 41 and the second motor 51, molds of different sizes can be clamped. Cylinders 21 distributed in a rectangular array are fixedly arranged on the lower surface of the processing table 1. The lower surface of the cylinders 21 is fixedly provided with a bottom plate 2. The lower end of the first motor 41 is fixedly connected with the upper surface of the bottom plate 2. The upper surface of the bottom plate 2 is fixedly connected with the lower surfaces of the two fixed blocks 45. The bottom plate 2 and the cylinders 21 are arranged to support the processing table 1. A rectangular cover 54 is fixedly arranged on the lower surface of the processing table 1. One end of the two tooth plates 53 movably penetrates through the outside of the rectangular cover 54. By arranging the rectangular cover 54, the tooth plates 53 are limited. Guide rods 44 are fixedly arranged on the opposite sides of the fixed blocks 45. The two ends of the guide rods 44 respectively movably penetrate through the two first clamping blocks 46. By arranging the guide rods 44, the bidirectional threaded rod 43 is limited. Second grooves 55 are opened on the opposite sides of the two second clamping blocks 56. The second grooves 55 are used in cooperation with the tooth plates 53. By the cooperation of the second grooves 55 and the tooth plates 53, the second clamping blocks 56 can move towards each other for a longer distance. First baffles 6 are fixedly arranged on the opposite sides of the first clamping blocks 46 and the second clamping blocks 56. Through holes 13 distributed in a rectangular array are opened inside the processing table 1. The first baffles 6 and the through holes 13 are used in cooperation. By the cooperation of the first baffles 6 and the through holes 13, when the first clamping blocks 46 and the second clamping blocks 56 move, part of the first groove 12 can be blocked. Second baffles 7 are fixedly connected to the opposite sides of the first clamping blocks 46 and the second clamping blocks 56. By arranging the second baffles 7, when the first clamping blocks 46 and the second clamping blocks 56 move, the other part of the first groove 12 can be blocked.

[0021] A protective cover 3 is fixedly provided on the upper surface of the processing table 1. Symmetrically distributed support plates 11 are fixedly provided on the outer side of the processing table 1. An air extraction pump 31 is fixedly provided on the upper surface of the support plate 11. A collection box 32 is fixedly provided on the upper surface of the processing table 1. An air inlet 33 is fixedly provided on the upper surface of the collection box 32. The pump body inlets of the two air extraction pumps 31 are communicated with the collection box 32 through pipes. A filter screen 34 is fixedly provided on one side of the interior of the collection box 32 close to the air extraction pump 31. By providing the air extraction pump 31 to absorb the debris after processing and providing the collection box 32 to collect the debris after processing, the accumulation of debris is prevented from affecting the processing of the mold by the equipment.

[0022] Working principle: First, install this positioning device on the processing equipment, place the mold to be processed on the processing table 1, start the first motor 41, the output shaft of the first motor 41 drives the bevel gear 42 to rotate, the rotation of the bevel gear 42 drives the bidirectional threaded rod 43 to rotate, the rotation of the bidirectional threaded rod 43 drives the two first clamping blocks 46 to move towards each other, the movement of the first clamping blocks 46 towards each other drives two of the first baffles 6 and two of the second baffles 7 to move towards each other. When the first clamping blocks 46 completely clamp both sides of the mold, start the second motor 51, the output shaft of the second motor 51 drives the first gear 52 to rotate, the rotation of the first gear 52 drives the toothed plate 53 to move towards each other, the movement of the toothed plate 53 towards each other drives the second clamping blocks 56 to move towards each other, the movement of the second clamping blocks 56 towards each other drives the other two first baffles 6 and the other two second baffles 7 to move towards each other, so that the second clamping blocks 56 clamp the other two sides of the mold, and clamping of the mold can be achieved from four directions, making it not easy for the mold to deviate from the center position during processing and not easy to loosen during processing. At the same time, molds of different sizes can also be clamped, improving the quality of mold processing and the processing efficiency. The first baffles 6 and the second baffles 7 are provided to block the first groove 12. When the processing is completed, start the air extraction pump 31. The air extraction pump 31 compresses and stretches the air in the pump cavity to form a negative pressure, creating a pressure difference between the air extraction port, the pipeline, the collection box 32 and the outside air, so as to suck the debris in the air into the collection box 32 through the air inlet 33. The absorbed debris will be blocked by the filter screen 34 and fall into the collection box 32, thus realizing the cleaning of the processing debris and preventing the accumulation of debris from affecting the processing of the mold by the equipment.
