[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0027] See attached document Figure 1 -Attached Figure 4 This utility model provides a positioning and clamping device for production molds, comprising:
[0028] Clamping base 1, with a placement block 2 fixedly connected to the top of clamping base 1, and clamping components provided on both sides of placement block 2;
[0029] The clamping assembly includes a movable block 3, which is set on the top of the clamping base 1. The top of the movable block 3 has a groove 4, and the bottom of the groove 4 has a cavity 5. A prism 6 is embedded inside the groove 4. A connecting plate 7 is fixedly connected to the top of the prism 6. A locking block 8 and a locking block 9 are fixedly connected to both sides of the connecting plate 7, respectively. A fixing pin 10 is embedded inside the prism 6. The fixing pin 10 has a T-shaped cross section. A movable plate 11 is fixedly sleeved on the bottom of the fixing pin 10. A fixing plate 12 is fixedly connected inside the cavity 5. The fixing pin 10 passes through the fixing plate 12. A spring 13 is sleeved on the outside of the fixing pin 10. The two ends of the spring 13 are fixedly connected to the fixing plate 12 and the movable plate 11, respectively. A slider 14 is fixedly connected to both sides of the movable plate 11. A sliding groove 15 is opened on both sides of the cavity 5. The two sliders 14 are respectively embedded in the two sliding grooves 15.
[0030] The movable plate 11 is slidably connected to the clamping seat 1, the prism 6 is slidably connected to the prism groove 4, the slider 14 is slidably connected to the slide groove 15, the fixing pin 10 is movably connected to the fixing plate 12 and the prism 6, and the top of the connecting plate 7 is fixedly connected to the pull block 21.
[0031] In this implementation plan, a first clamping block 8 and a second clamping block 9 are designed on both sides of the connecting plate 7. When in use, the connecting plate 7 can be pulled upward and then rotated to swap the positions of the first clamping block 8 and the second clamping block 9. In this way, the square and cylindrical production molds can be clamped and fixed when performing clamping and fixing work.
[0032] To achieve the movement of the movable block 3, the device employs the following technical solution: A connecting block 16 is fixedly connected to the top of the clamping base 1. A screw 17 is embedded inside the connecting block 16. The screw 17 is threadedly connected to the connecting block 16. A knob 18 is fixedly connected to one end of the screw 17, and a fixing pin 19 is fixedly connected to the other end of the screw 17. The fixing pin 19 has a T-shaped cross-section and is embedded inside the movable block 3. The fixing pin 19 is movably connected to the fixed block. Rotating the knob 18 causes the screw 17 and the fixing pin 19 to rotate. Since the screw 17 is threadedly connected to the connecting block 16, and the fixing pin 19 is movably connected to the movable block 3, the movable block 3 can be moved when the knob 18 is rotated.
[0033] In order to achieve the purpose of stable movement of the moving block 3, the device adopts the following technical solution: two guide rods 20 are fixedly embedded inside the placement block 2. Both guide rods 20 are fixedly connected to the clamping seat 1. Both guide rods 20 pass through the moving block 3 in the two clamping assemblies and are slidably connected to it. The guide rods 20 can make the moving block 3 move stably.
[0034] The usage process of this utility model is as follows: When it is necessary to position and clamp a square-shaped production mold, place the production mold on the placement block 2, and then rotate the knobs 18 on both sides. Rotating the knobs 18 will cause the screw 17 and the fixing pin 19 to rotate. Since the screw 17 is connected to the connecting block 16 by a thread, and the fixing pin 19 is movably connected to the moving block 3, they can rotate. Thus, when the knobs 18 are rotated, the two moving blocks 3 can move towards the middle, and the two clamping blocks 8 will come into contact with the production mold, thereby clamping and fixing it.
[0035] When it is necessary to position and clamp a cylindrical production mold, hold the pull block 21 and lift the connecting plate 7 upwards. This will allow the prism 6 to move out of the groove 4. During the movement, the fixing pin 19, the moving plate 11, and the two sliders 14 will all move upwards. At the same time, the spring 13 will be compressed. After the prism 6 is completely removed from the groove 4, rotate the pull block 21 to rotate the connecting plate 7 and the prism 6 half a turn. During the rotation, since the slider 14 is embedded in the groove 15, the fixing pin 10 will not rotate. After rotating half a turn, the positions of the locking blocks 18 and 29 will be swapped. Then, slowly lower the pull block 21. At the same time, the spring 13 will rebound and allow the prism 6 to be embedded in the groove 4 again. Then, in the same way, swap the positions of the other locking blocks 18 and 29. Then, place the cylindrical production mold on the placement block 2. Then, rotate the knobs 18 on both sides to make the two locking blocks 29 hold and clamp the production mold, thereby clamping and fixing the cylindrical production mold.
[0036] The screw 17 and the connecting block 16 are connected by threads, and the threaded connection is a self-locking result. This means that after clamping and fixing, the two moving blocks 3 will not move outward and cause the screw 17 to rotate, thus preventing the clamping from loosening.
[0037] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model shall fall within the scope of protection claimed by this utility model.
