[0011] Preferably, a third connection hole is provided on the side wall of the support frame away from the transmission gear, and the size of the third connection hole is adapted to the cylinder away from the transmission gear.

[0012] Preferably, a rotating ring is installed on the cylinder away from the transmission gear. The cross-section of the outer surface of the rotating ring is semicircular. A rotating groove is provided on the support frame. The rotating groove is connected to the third connection hole and is adapted to the rotating ring.

[0013] The beneficial effects of the present utility model are:

[0014] In the present utility model, by activating two cylinders, the output shafts of the cylinders extend to clamp the mold between two clamping pieces. Then, the polishing mechanism is activated to polish the mold. When the surface of the mold facing the polishing mechanism is polished, the motor is activated. The motor drives the connecting rod to rotate, thereby pushing the sliding member to move, causing the rack connected to the sliding member to reciprocate horizontally. This drives the transmission gear meshing with the rack to rotate, supporting the rotation of the cylinder connected to the transmission gear. Since the same mold is clamped between the two cylinders, the cylinder away from the transmission gear and the mold between the two cylinders rotate synchronously, thus achieving the purpose of flipping the mold and polishing the unpolished surface of the mold. This device is easy to operate. The flipping of the mold can be completed by the parts on it, which can meet the requirement of polishing the mold comprehensively, avoiding the traditional operation of manually turning over the mold, with high work efficiency and low labor cost.

Detailed Embodiment

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Refer to Figures 1-4, A cutting and polishing device for injection mold processing, including a base 1, a U-shaped bracket 2 is installed on the base 1, a polishing mechanism 3 is installed at the top of the U-shaped bracket 2, a motor 4 is installed on the outer wall of the U-shaped bracket 2, the output shaft of the motor 4 passes through the side wall of the U-shaped bracket 2 and is connected to a connecting rod 5, a support frame 6 is installed on the base 1, a rack 7 is slidably installed on the side of the support frame 6 close to the motor 4, a sliding member 8 is installed on the rack 7, and the end of the connecting rod 5 away from the motor 4 is slidably fitted on the sliding member 8. A transmission gear 9 is engaged with the rack 7, and the transmission gear 9 is rotatably installed on the support frame 6. Cylinders 10 are rotatably installed on both the U-shaped bracket 2 and the support frame 6. The two cylinders 10 are arranged oppositely, and the cylinder 10 close to the motor 4 is connected to the transmission gear 9. Clamping pieces 11 are connected to the output shafts of both cylinders 10.

[0022] When using this device, the staff first turns on the two cylinders 10. The output shafts of the cylinders 10 extend to clamp the mold between the two clamping pieces 11. Then, the polishing mechanism 3 is started to polish the mold. When the surface of the mold facing the polishing mechanism 3 is polished, the motor 4 is turned on. The motor 4 drives the connecting rod 5 to rotate, thereby pushing the sliding member 8 to move, causing the rack 7 connected to the sliding member 8 to reciprocate horizontally, thereby driving the transmission gear 9 engaged with the rack 7 to rotate, supporting the cylinder 10 connected to the transmission gear 9 to rotate. Since the same mold is clamped between the two cylinders 10, the cylinder 10 far from the transmission gear 9 and the mold between the two cylinders 10 rotate synchronously, so as to achieve the purpose of flipping the mold and polishing the unpolished surface of the mold. This device is easy to operate. The flipping of the mold can be completed by the parts on it, which can meet the requirements of all-round polishing of the mold, avoid the traditional operation of manually turning the mold over, and has high work efficiency and low labor cost.

[0023] Specifically, in this embodiment, a first connection hole 12 is opened on the side wall surface of the U-shaped bracket 2 close to the motor 4. The center of the first connection hole 12 and the center of the motor 4 are on the same axis, so that the output end of the motor 4 can pass through the side wall of the U-shaped bracket 2 through the first connection hole 12 and be connected to the connecting rod 5, thereby realizing the power transmission between the motor 4 and the connecting rod 5.

[0024] Specifically, in this embodiment, a limit block 13 is installed on the rack 7, and a limit groove 14 is opened on the side wall surface of the support frame 6 close to the rack 7. The limit block 13 is slidably fitted in the limit groove 14, so that the rack 7 can be slidably connected to the support frame 6 through the adaptability of the limit block 13 and the limit groove 14, thereby providing a guarantee for the movement of the rack 7 on the support frame 6.

[0025] Specifically, in this embodiment, a slider 15 is installed at one end of the connecting rod 5 away from the motor 4. A sliding groove 16 is formed in the sliding member 8, and the sliding groove 16 is adapted to the slider 15, so that the slider 15 can be slidably connected to the sliding member 8 through the sliding groove 16. Thus, when the connecting rod 5 rotates, the sliding member 8 can be driven to move synchronously.

[0026] Specifically, in this embodiment, a second connection hole 17 is formed in the support frame 6. The second connection hole 17, the cylinder 10, and the center of the transmission gear 9 are on the same axis, so that the cylinder 10 close to the transmission gear 9 can be connected to the transmission gear 9 through the second connection hole 17. At the same time, the cylinder 10 can be rotatably connected to the support frame 6 through the second connection hole 17, so that when the transmission gear 9 rotates, the cylinder 10 can be driven to rotate synchronously.

[0027] Specifically, in this embodiment, a third connection hole 18 is formed in a side wall surface of the support frame 6 away from the transmission gear 9. The third connection hole 18 is adapted to the size of the cylinder 10 away from the transmission gear 9, so that the cylinder 10 can be rotatably installed on the support frame 6 through the third connection hole 18, thereby providing a supporting force for the cylinder 10 through the support frame 6.

[0028] Specifically, in this embodiment, a rotating ring 19 is installed on the cylinder 10 away from the transmission gear 9. The cross-section of the outer curved surface of the rotating ring 19 is semicircular. A rotating groove 20 is formed in the support frame 6. The moving groove 20 is communicated with the third connection hole 18, and the rotating groove 20 is adapted to the rotating ring 19, so that the cylinder 10 can be rotatably connected to the support frame 6 through the adaptability of the rotating ring 19 and the rotating groove 20. At the same time, the cylinder 10 is limited to a fixed position through the rotating ring 19, thereby avoiding the situation that the mold falls off due to the position deviation when the cylinder 10 rotates.
