[0025] Example 1

[0026] A rotating device for precision mold production, such as Figure 1-Figure 4As shown, it includes a supporting shell 1, a rotating shaft 11, a turntable 12, a fixing frame 13, a mold 14 and a weighting mechanism.

[0027] like Figure 3 and Figure 4 As shown, the weighting mechanism includes a giant gear 2, a pinion 21 and a connecting block 22. The left and right sides of the support shell 1 are rotatably connected to the giant gears 2 that are symmetrically distributed front and back.

The weight of the multiple connecting blocks 22 is higher than the weight of the mold 14 and the internal material. The end of the rotating shaft 11 away from the turntable 12 is fixedly connected to the pinion 21, and the pinion 21 is meshed with the giant gear 2 on the same side.

[0028] like Figure 5 and Figure 6 As shown, it also includes a knocking block 3, a connecting disk 31, a spring 32 and a top block 33. The left and right sides of the support shell 1 are slidably connected with the circumferentially distributed knocking blocks 3, and the spring 32 is fixedly connected between the knocking block 3 and the support shell 1. The connecting disk 31 is fixedly connected to the outer side of the turntable 12, and the top block 33 is fixedly connected to the outer side of the connecting disk 31. The knocking block 3 is in contact with the top block 33, and the movement of the top block 33 will squeeze and push the knocking block 3.

[0029] like Figure 7 and Figure 8 As shown, it also includes a top frame 4, a connecting frame 41, a connecting rod 42, a rack 43, a spur gear 44, a rotating rod 45, a ratchet 46, a pawl 47, a tension spring 48, a telescopic rod 49 and a top spring 410. The supporting shell 1 is slidably connected to the connecting rod 42, the top of the connecting rod 42 is fixedly connected to the connecting frame 41, the connecting frame 41 is in contact with the mold 14, the left and right sides of the connecting frame 41 are fixedly connected to the top frame 4, the top frame 4 is in contact with the turntable 12, the right side of the connecting rod 42 is fixedly connected to the rack 43, and the supporting shell 1 is slidably connected to the connecting rod 42. The top of the connecting rod 42 is fixedly connected to the top frame 41, and the top frame 4 is in contact with the turntable 12. The right side of the connecting rod 42 is fixedly connected to the rack 43. A rotating rod 45 is rotatably connected inside the shell 1, and a spur gear 44 is fixedly connected to the rear end of the rotating rod 45, and the spur gear 44 is meshed with the rack 43. A ratchet 46 is fixedly connected to the front end of the rotating rod 45. A pawl 47 is rotatably connected to the front side of the supporting shell 1, and the pawl 47 is in contact with the ratchet 46. A tension spring 48 is fixedly connected between the pawl 47 and the supporting shell 1. A telescopic rod 49 is fixedly connected inside the supporting shell 1, and the top end of the telescopic rod 49 is fixedly connected to the bottom end of the connecting rod 42, and a top spring 410 is fixedly connected between the telescopic rod 49 and the connecting rod 42.

[0030] like Figure 6 As shown, the side of the knocking block 3 close to the connecting plate 31 is designed as an inclined surface.

[0031] like Figure 8 As shown, the surfaces of the top frame 4 and the connecting frame 41 are both made of rubber material, which is used to prevent the top frame 4 and the connecting frame 41 from causing wear to the connecting plate 31 and the mold 14.

[0032] When workers need to use the mold 14 to produce products, they can first fill the mold 14 with materials, and then fix the mold 14 between the fixing frames 13 on both sides. At this time, the top frame 4 can hold the turntable 12 against the turntable 12 to prevent the turntable 12 from rotating and affecting the installation of the mold 14. After the mold 14 is installed, the rotating shaft 11 can be driven to rotate by an external device, thereby driving the turntable 12, the fixing frame 13 and the mold 14 to rotate clockwise. The rotation of the mold 14 will squeeze the connecting frame 41, so that the top frame 4, the connecting frame 41, the connecting rod 42 and the rack 43 and other components all move downward. At this time, the top frame 4 is separated from the turntable 12, and the telescopic rod 49 and the top spring 410 are immediately When the rack 43 is compressed, the downward movement of the rack 43 will cause the spur gear 44, the rotating rod 45 and the ratchet 46 to rotate counterclockwise. The counterclockwise rotation of the ratchet 46 will squeeze the pawl 47, causing the pawl 47 to move to the left, and the tension spring 48 will be compressed immediately. When the ratchet 46 no longer rotates, the pawl 47 moves to the right under the action of the tension spring 48 to contact the ratchet 46, and the ratchet 46 cannot rotate in the reverse direction. Therefore, the connecting rod 42 cannot move upward to reset. At the same time, the rotation of the rotating shaft 11 will drive the giant gear 2 to rotate through the pinion 21. Since the weight of the multiple connecting blocks 22 fixed to the giant gear 2 is higher than the weight of the mold 14 and the material, the rotating shaft 1 1 The rotation force is relatively uniform and is less affected by the change of the center of gravity of the mold 14 and the material, so the rotating shaft 11 can drive the mold 14 to rotate at a uniform speed through the turntable 12 and other components. At the same time, the rotation of the turntable 12 will drive the connection disk 31 to rotate, and the rotation of the connection disk 31 will move the top block 33. The movement of the top block 33 will first squeeze the knocking block 3 and make the knocking block 3 move away from the connection disk 31, and the spring 32 will be compressed immediately. When the top block 33 continues to move to separate from the knocking block 3, the knocking block 3 will move towards the direction close to the connection disk 31 under the action of the spring 32 resetting, and knock the connection disk 31 and make the mold 14 vibrate, thereby avoiding material accumulation and product After the pouring is completed, the turntable 12 and the mold 14 no longer rotate. At this time, the worker can push the pawl 47 to the left until the ratchet 46 is no longer restricted. At this time, the connecting rod 42 and the rack 43 move upward and reset under the action of the tension spring 48 until the top frame 4 and the connecting frame 41 contact the turntable 12 and the fixed frame 13 respectively, preventing the turntable 12 from rotating while supporting the mold 14, which is convenient for the workers to disassemble. The ratchet 46, the spur gear 44 and the rotating rod 45 rotate counterclockwise and reset under the action of the rack 43, and then the worker can release the pawl 47, and the pawl 47 moves to the right under the action of the tension spring 48 to contact the ratchet 46 and return to its original position.
