[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-5 As shown, this utility model provides an automatic edge-cutting sprayer injection mold, including a fixed mold 1 and a moving mold 2. A first mold plate 3 is embedded inside the fixed mold 1, and a second mold plate 4 is embedded inside the moving mold 2. A mold groove 5 is provided between the first mold plate 3 and the second mold plate 4. The mold also includes: The edge trimming mechanism, located inside the fixed mold 1, is used to remove burrs from the sprayer nozzle. The burr removal component, which is mounted on the edge cutting mechanism, is used to remove the burrs after cutting. The edge-cutting structure includes a pneumatic cylinder 6, which is fixed to the bottom of the inner cavity of the fixed mold 1. A first fixed frame 7 is connected to the top of the pneumatic cylinder 6. A second fixed frame 8 is fixed on both sides of the top of the first fixed frame 7. A cutter head 9 is fixed to the top of the second fixed frame 8. A sliding groove 11 is opened inside the first mold plate 3. The chip removal assembly includes a hose 12, which is embedded inside the fixed mold 1. An exhaust pipe 10 is provided inside the first fixed frame 7. A discharge groove 13 is provided between the fixed mold 1 and the hose 12. A slot 14 is provided inside the second mold plate 4. A reset spring 15 and a movable part 16 are sleeved on the inner wall of the slot 14.

[0019] By operating the pneumatic cylinder 6, the first fixed frame 7 can be controlled to drive the two sets of second fixed frames 8 to move upward, so that the cutter head 9 passes through the slide groove 11. At the same time, through the cooperation between the movable part 16 and the groove 14, the cutter head 9 pushes the movable part 16 to separate from the mold groove 5 when it moves upward. At this time, the cutter head 9 will cut off the burrs of the sprayer nozzle, thereby improving the quality of the finished product.

[0020] like Figure 3 As shown, the two ends of the exhaust pipe 10 pass through two sets of second fixing brackets 8 respectively. The second fixing brackets 8 are slidably connected to the slide groove 11, and the top of the cutter head 9 passes through the slide groove 11.

[0021] Through the design of the exhaust pipe 10 and the cooperation between the hose 12 and the exhaust pipe 10, airflow can be input to the exhaust pipe 10 through the hose 12. After the cutter head 9 passes through the slide groove 11, the gas input to the exhaust pipe 10 will be discharged from the slide groove 11. Through the cooperation between the mold groove 5 and the discharge groove 13, the burrs after removal are discharged between the fixed mold 1 and the moving mold 2, which facilitates continuous operation.

[0022] like Figure 2 , 3 As shown, the top end of the hose 12 is connected to the exhaust pipe 10, and the tail end of the hose 12 is connected to an external air pump.

[0023] The design of the hose 12 allows for connection to an external air pump. Through the cooperation between the hose 12 and the exhaust pipe 10, the airflow input into the hose 12 will be input into the interior of the exhaust pipe 10. Finally, the airflow will be discharged from the exhaust pipe 10. At this time, the airflow will pass through the slide 11, the mold groove 5 and the discharge groove 13 and be discharged together with the removed burrs.

[0024] like Figure 2 As shown, one side of the mold groove 5 is connected to the discharge groove 13, and the discharge groove 13 extends through to the outside of the fixed mold 1 and the moving mold 2.

[0025] The mold groove 5 and the discharge groove 13 cooperate to facilitate the discharge of the cut-off burrs. Since the discharge groove 13 is connected to the outside, it is convenient to discharge the burrs that have been removed.

[0026] like Figure 3 As shown, the top of the blade 9 corresponds to the position of the sprayer nozzle.

[0027] The first fixed frame 7 and the second fixed frame 8 are moved upward by the pneumatic cylinder 6, which can drive the cutter head 9 through the slide groove 11. Since the top of the cutter head 9 corresponds to the position of the sprayer nozzle, the cutter head 9 is used to remove the burrs of the sprayer nozzle.

[0028] like Figure 3 As shown, the bottom end of the movable part 16 passes through the slot 14 and corresponds to the position of the slide groove 11.

[0029] The design of the movable part 16 can block one side of the mold groove 5, preventing liquefied plastic from flowing out during injection molding of the sprayer.

[0030] like Figure 3 As shown, the reset spring 15 is elastically supported between the slot 14 and the movable part 16, and the top of the cutter head 9 is in contact with the bottom of the movable part 16.

[0031] The design of the return spring 15 enables the movable part 16 to have good elastic return performance. Since the return spring 15 is in a compressed state, it will apply an elastic force to the movable part 16, thereby driving the movable part 16 to block one side of the mold groove 5.

[0032] Working principle: By operating the pneumatic cylinder 6, the first fixed frame 7 can be controlled to drive the two sets of second fixed frames 8 to move upward, so that the cutter head 9 passes through the slide groove 11. At the same time, through the cooperation between the movable part 16 and the groove 14, the cutter head 9 pushes the movable part 16 to separate from the mold groove 5 when it moves upward. At this time, the cutter head 9 will cut off the burrs of the sprayer nozzle. Then, the air pump is used to input airflow into the exhaust pipe 10 through the hose 12. After the cutter head 9 passes through the slide groove 11, the air input into the exhaust pipe 10 will be discharged from the slide groove 11. Through the cooperation between the mold groove 5 and the discharge groove 13, the cut burrs are discharged from between the fixed mold 1 and the moving mold 2.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
