[0002] In order to prevent the mold from shifting during the processing of the mold, the mold needs to be fixed.

[0003] A search of Chinese patent CN221475906U reveals a mold positioning and locking device, comprising a base plate mounted on top of a plastic injection molding machine, a positioning block mounted on the base plate, a mold groove for placing a plastic mold on the top of the positioning block, a clamping block inside the mold groove, and a locking knob on the side wall of the positioning block. The locking knob passes through the positioning block and abuts against the clamping block, and is threadedly connected to the positioning block. By rotating the locking knob, the clamping block presses the plastic mold, thus fixing the plastic mold; by rotating the locking knob, the clamping block releases the plastic mold, allowing the plastic mold to be removed and replaced with different types of plastic molds, thereby meeting the production needs of various plastic products.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] While the aforementioned technology can fix different types of molds, fixing the mold requires continuously rotating the locking knob to drive the clamping block to fix the mold, which is quite cumbersome. Utility Model Content

[0027] This utility model provides an improved fixing and locking device for mold production. The technical solution of this utility model is as follows:

[0028] like Figures 1 to 4 As shown, a fixing and locking device for mold production includes a processing table 1, on which two fixing plates 2 are provided. The fixing plates 2 are rectangular plates. A left adjustment groove 3 and a right adjustment groove 4 are respectively opened on the processing table 1 corresponding to the two fixing plates 2. A slider 5 is movably installed inside the left adjustment groove 3 and the right adjustment groove 4. The slider 5 is a rectangular block. The left adjustment groove 3 and the right adjustment groove 4 are respectively fixedly connected to the two sliders 5. A drive shaft 6 is movably installed between the left adjustment groove 3 and the right adjustment groove 4. The drive shaft 6 is cylindrical and has two opposite threads. The drive shaft 6 is threadedly connected to the two sliders 5. A base 7 is fixedly installed at the bottom of the processing table 1. The base 7 is rectangular and has a movable groove 8. The movable groove 8 is a rectangular groove. A pressure plate 9 is movably installed above the movable groove 8. The pressure plate 9 is rectangular. A transmission mechanism is provided between the processing table 1 and the base 7.

[0029] The transmission mechanism includes a transmission groove 10, a rotating shaft 11, transmission gears 12, a transmission belt 13, a drive gear 14, and a drive rack 15. The transmission groove 10 is a rectangular groove located inside the upper part of the base 7. The rotating shaft 11 is cylindrical and is movably mounted inside the lower part of the transmission groove 10. There are two transmission gears 12, which are respectively fixedly sleeved on the rotating shaft 11 and the transmission shaft 6. The transmission belt 13 is sleeved between the two transmission gears 12 and meshes with them for transmission. The drive gear 14 is fixedly sleeved on the rotating shaft 11. The drive rack 15 is a long strip structure and is fixedly mounted on the pressure plate 9. The top wall has a drive rack 15 and a drive gear 14 meshing with each other. Through the transmission mechanism, when it is necessary to fix the mold, the mold is placed on the processing table 1, and then the pressure plate 9 is pressed down. The pressure plate 9 then drives the drive rack 15 to move downward. The drive rack 15 and the drive gear 14 mesh and transmit power. The drive rack 15 can then drive the drive gear 14 to rotate. The drive gear 14 can then drive the rotating shaft 11 to rotate. The rotating shaft 11 then drives the transmission shaft 6 to rotate through the transmission gear 12 and the transmission belt 13. The transmission shaft 6 is threadedly connected to two sliders 5, so that the two sliders 5 can drive the two fixed plates 2 to move towards each other, thereby clamping and fixing the mold.

[0030] An installation rod 16 is fixedly installed inside the movable groove 8. The installation rod 16 is cylindrical and extends upward through the upper and lower walls of the pressure plate 9. An installation spring 17 is sleeved on the installation rod 16. An installation groove 18 is provided inside the pressure plate 9. The installation groove 18 is rectangular. A movable plate 19 is movably installed inside the installation groove 18. The movable plate 19 is rectangular. A limit rod 20 is fixedly installed on the movable plate 19. The limit rod 20 is cylindrical. Multiple limit grooves 22 are provided on the inner wall of the movable groove 8. One end of the limit rod 20 is located inside one of the limit grooves 22. An installation spring 21 is provided inside the installation groove 18 and is sleeved on the limit rod 20. After the pressure plate 9 moves to fix the mold, the movable plate 19 can be pushed. The movable plate 19 causes the limit rod 20 to move into the limit groove 22. At this time, the position of the pressure plate 9 will be fixed, so that releasing the pressure plate 9 will not cause the mold to loosen.

[0031] Protective pads 23 are installed on both fixing plates 2. The protective pads 23 are made of soft material and have a rough surface. The protective pads 23 can increase the friction between the mold and the mold, and at the same time avoid the mold being damaged due to rigid contact between the fixing plates 2 and the mold.

[0032] The specific working method is as follows:

[0033] With the transmission mechanism in place, when the mold needs to be fixed, the mold is placed on the processing table 1, and then the pressure plate 9 is pressed down. The pressure plate 9 then drives the drive rack 15 to move downward. The drive rack 15 meshes with the drive gear 14, which in turn drives the drive gear 14 to rotate. The drive gear 14 then drives the rotating shaft 11 to rotate. The rotating shaft 11 then drives the drive shaft 6 to rotate through the transmission gear 12 and the transmission belt 13. The drive shaft 6 is threadedly connected to the two sliders 5, so that the two sliders 5 can drive the two fixing plates 2 to move towards each other, thereby clamping and fixing the mold. This achieves the effect of easily fixing the mold, and the operation is simple and quick.
