DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-4 The utility model is described in further detail.

[0023] The utility model embodiment discloses a mold turning device, referring to Figure 1-Figure 4, including a base plate 1, a fixing frame 2 is fixedly installed on the upper end of the base plate 1, a mounting plate 3 is fixed on the inner surface of the fixing frame 2, a hand wheel 4 is installed on the outer side of the fixing frame 2, the hand wheel 4 passes through the fixing frame 2 and is connected with a transmission screw 5, the other end of the transmission screw 5 is rotatably connected to the inner side of the fixing frame 2, and the outer surface of the transmission screw 5 is threadedly connected with a first movable block 6. When the hand wheel 4 is rotated, the transmission screw 5 is driven to rotate on the inner side of the fixing frame 2, thereby driving the first movable block 6 to continuously approach one side of the mounting plate 3, both ends of the first movable block 6 are movably connected with connecting rods 7, and the other ends of the two connecting rods 7 are movably connected with second movable blocks 9, and a rack plate 10 is fixedly installed on the outer side of the second movable block 9. When the two second movable blocks 9 drive the connecting rods 7 to move, they cannot drive the first movable block 6 to move, thereby enhancing the self-locking effect of the device. When one side of the mounting plate 3 moves, it will drive the two connecting rods 7 to stretch to both sides, and push the two second movable blocks 9 to both sides. The bottom of the rack plate 10 is meshed and connected with a transmission gear 13. When the processing mold is flipped to the required angle, the hand wheel 4 is released, and the position of the first clamp 14 is fixed by the teeth of the rack plate 10 and the transmission gear 13. A rotating rod 12 is fixedly installed on the outer side of the transmission gear 13, and the other end of the rotating rod 12 is fixedly installed with the first clamp 14. When the two second movable blocks 9 drive the rack plate 10 to move horizontally to both sides, the rotating rods 12 on the inner sides of the two bearing seats 11 drive the mold to flip at multiple angles through the meshing action of the transmission gear 13 and the rack plate 10. Compared with the traditional flipping device, the device can be flipped 360 degrees or any degree, which enhances the applicability and flexibility of the device.

[0024] Reference Figure 2-Figure 3 Two slide grooves 8 are evenly arranged in the middle of the mounting plate 3, and the outer surfaces of the two second movable blocks 9 are respectively slidably connected with the inside of the two slide grooves 8. The two second movable blocks 9 are connected with the slide grooves 8. When the connecting rod 7 drives the second movable block 9 to move, the stability of the horizontal movement of the second movable block 9 is enhanced. Two bearing seats 11 are fixedly installed on the top of the base plate 1. The inner side of the bearing seat 11 is provided with a bearing. The two rotating rods 12 are respectively rotatably connected with the inside of the two bearing seats 11. When the two rotating rods 12 rotate, the friction with the inner side of the bearing seat 11 is reduced by cooperating with the inner bearing of the bearing seat 11, thereby enhancing the rotation effect of the rotating rod 12.

[0025] Reference Figure 1-Figure 4A hydraulic cylinder 15 is installed on the right side of the substrate 1. The output end of the hydraulic cylinder 15 passes through the substrate 1 and is connected to a movable plate 16. The inner side of the movable plate 16 is evenly rotated and connected to two second clamps 18. When the first clamp 14 is driven to rotate through the rotating rod 12, the second clamp 18 rotates on the inner side of the movable plate 16 at the same time to ensure that the mold can be turned over normally. The two second clamps 18 correspond to the two first clamps 14 respectively. Two slide rails 17 are evenly provided on the inner side of the right end of the substrate 1. The two ends of the movable plate 16 are respectively slidably connected to the inner sides of the two slide rails 17. Under the action of the hydraulic cylinder 15, the movable plate 16 and the second clamp 18 can be driven to move, and the distance between the first clamp 14 and the second clamp 18 can be adjusted, so as to facilitate the clamping of molds of different sizes, further enhancing the applicability of the device.

[0026] The implementation principle of a mold flipping device in an embodiment of the utility model is as follows: when using the device, the mold to be processed is placed on the inner side of the first clamp 14, so that the first clamp 14 clamps one side of the mold, and then the hydraulic cylinder 15 is started to drive the movable plate 16 to move toward one side of the first clamp 14. When adjusted to a suitable position, the other end of the mold is clamped and fixed by the second clamp 18 to ensure the stability of the mold between the two clamps. When flipping, first turn the hand wheel 4 to drive the transmission screw 5 to rotate on the inner side of the fixed frame 2, thereby driving the first movable block 6 to continuously approach one side of the mounting plate 3. At this time, the two second movable blocks 9 are pushed to both sides under the extrusion action of the two connecting rods 7, so that the second movable block 9 drives the rack plate 10 to perform corresponding horizontal activities, so that the rotating rods 12 on the inner sides of the two bearing seats 11 drive the mold to be flipped at multiple angles through the meshing action of the transmission gear 13 and the rack plate 10.
