The two first sliding rods 11 are respectively slidably connected to the two second chute openings 4, and clamping plates 12 are fixed at their other ends. A screw rod 15 is also fixed at the bottom end of the second L-shaped rod 8. A gear 6 is also movably connected to the outer side of the side plate 2 through a rotating shaft 5. The gear 6 is located between the first L-shaped rod 7 and the second L-shaped rod 8 and is in meshing transmission with a number of first racks 9 and a number of second racks 10; there are two moving blocks 16 and a driving mechanism in the working frame 1. Bearings 17 are fixed on both the two moving blocks 16, and screw tubes 18 are connected to the bearings 17. The bottom ends of the two screw rods 15 are respectively located in the two screw tubes 18 and are threadedly connected thereto. Using the positioning device for a milling machine for mold processing, the position of the clamping plate 12 can be freely adjusted without disassembly, and the positioning effect is better, meeting the processing requirements of enterprises.

[0021] Specifically, the driving mechanism includes a hydraulic cylinder 21, a first transmission wheel 19 and a second transmission wheel 20. The hydraulic cylinder 21 is fixed to the inner wall of the working frame 1, and its piston rod is connected to a bearing block 22. A driving motor 23 is installed at the bottom end of the bearing block 22, and its output end is connected to a third transmission wheel 24. The first transmission wheel 19 and the second transmission wheel 20 are respectively fixed on the sides of the two screw tubes 18 and are respectively connected to the third transmission wheel 24 through a first conveyor belt 25 and a second conveyor belt 26. By driving the third transmission wheel 24 to rotate through the driving motor 23, the third transmission wheel 24 drives the first transmission wheel 19 and the second transmission wheel 20 to rotate respectively through the first conveyor belt 25 and the second conveyor belt 26. At this time, the screw tubes 18 rotate and drive the screw rods 15 to move upward. Finally, the second L-shaped rod 8 drives the clamping plate 12 to move inward, and through meshing transmission, the first L-shaped rod 7 also drives the clamping plate 12 to move inward to clamp and position the mold. Moreover, the piston rod of the hydraulic cylinder 21 drives the bearing block 22 and the third transmission wheel 24 to move, so that it drives the first transmission wheel 19 and the second transmission wheel 20 to move through the first conveyor belt 25 and the second conveyor belt 26 to adjust the distance between the two side plates 2, thereby realizing the adjustment of the position of the clamping plate 12.

[0022] Furthermore, a second sliding rod 32 is also fixed in the working frame 1. Both of the two moving blocks 16 are slidably connected to the second sliding rod 32, so that the moving tracks of the moving blocks 16 are constant.

[0023] Furthermore, chute grooves 30 are opened on the outer sides of the two side plates 2. A slider 31 located in the chute groove 30 is fixed on the second L-shaped rod 8, so that the L-shaped rod 8 can drive the side plate 2 to move.

[0024] Further, two guide rods 28 are provided on the inner sides of the side plates 2. Both ends of the guide rods 28 are fixedly connected to the side plates 2 through fixing blocks 27. Guide blocks 29 are fixedly provided on both sides of the clamping plates 12, and the guide blocks 29 are slidably connected to the guide rods 28, so as to prevent the clamping plates 12 from rotating and affecting their clamping effect.

[0025] Further, clamping blocks 14 are fixedly provided on the inner sides of a plurality of clamping plates 12 through two connecting rods 13.

[0026] The working principle of the present utility model is as follows: First, start the hydraulic cylinder 21, and its piston rod drives the bearing block 22 to move, so that the third driving wheels 24 drive the first driving wheel 19 and the second driving wheel 20 to move through the first conveyor belt 25 and the second conveyor belt 26 respectively. At this time, both L-shaped rods 8 drive the side plates 2 to move inwards or outwards simultaneously to adjust the clamping plates 12 to a suitable position. Then, place the mold between the two side plates 2 and make its two ends located between the two clamping plates 12 respectively. Next, start the driving motor 23, and its output end drives the third driving wheel 24 to rotate, so that the third driving wheel 24 drives the first driving wheel 19 and the second driving wheel 20 to rotate through the first conveyor belt 25 and the second conveyor belt 26 respectively. At this time, the screw tube 18 rotates and drives the screw rod 15 to move upwards. Finally, the second L-shaped rod 8 drives the clamping plates 12 to move inwards and drives the first L-shaped rod 7 to also drive the clamping plates 12 to move inwards through meshing transmission to clamp the mold tightly. The positioning effect of this device is good, enabling the subsequent processing work to proceed smoothly.
