[0027] Please refer to Figures 1-4 , the present invention provides a technical solution: an automatic spraying device for mold release agent, including a forming mold body 1 and a controller.

[0028] The mold release agent automatic spraying driving assembly 2 includes a fixed seat 21 located on one side of the top of the shell above the mold opening of the forming mold body 1.

[0029] It should be noted that in this embodiment, the first electric telescopic rod 22 and the second electric telescopic rod 23 are electrically connected to the controller through wires. The controller receives the visual information of the visual positioning camera at the bottom of the second electric telescopic rod 23, automatically calculates and adjusts the running tracks of the first electric telescopic rod 22 and the second electric telescopic rod 23, so that the spraying mechanism can flexibly enter the interior of the mold after mold opening for precise spraying.

[0030] Please refer toFigure 1 , 3 and 4, the mold release agent spiral spraying mechanism 3 includes a horizontal displacement component 31, a vertical displacement component 32 and a nozzle fixing frame 33; the horizontal displacement component 31 includes a first sliding guide rail 311, a first driving displacement screw 312 and a first sliding block 313. The first driving displacement screw 312 is parallel and located at the top of the first sliding guide rail 311. Both ends of the first driving displacement screw 312 are fixed to the top ends of both ends of the first sliding guide rail 311 through first bearing seats 3121. The first sliding block 313 is slidably penetrated on the first driving displacement screw 312. The bottom of the first sliding block 313 is slidably connected to the first sliding guide rail 311 through a sliding card slot; the vertical displacement component 32 includes a second sliding guide rail 321, a second displacement screw 322 and a second sliding block 323. One end of the bottom of the second sliding guide rail 321 is fixedly connected to the bottom of the first sliding block 313. The second displacement screw 322 is parallel and located on the second sliding guide rail 321. Both ends of the second displacement screw 322 are fixed to the top ends of both ends of the second sliding guide rail 321 through second bearing seats 3221. The second sliding block 323 is slidably penetrated on the second displacement screw 322. The bottom of the second sliding block 323 is slidably connected to the second sliding guide rail 321 through a sliding card slot; the nozzle fixing frame 33 is fixed to the outer wall of one side of the second sliding block 323. The nozzle fixing frame 33 is provided with a fixing groove for fixing the mold release agent nozzle. A vision camera is arranged at the bottom of the nozzle fixing frame 33. The vision camera is electrically connected to the controller through a wire; one end of the outer wall of the first sliding guide rail 311 is connected with a first motor 314. The first driving displacement screw 312 penetrates through the first bearing seat 3121 and is connected to the output end of the first motor 314 through a coupling; one end of the outer wall of the second sliding guide rail 321 is connected with a second motor 324. The second displacement screw 322 penetrates through the second bearing seat 3221 and is connected to the output end of the second motor 324; both the first motor 314 and the second motor 324 are electrically connected to the controller through wires.

[0031] It should be noted that in this embodiment, the present application sets the mold release agent spiral spraying mechanism 3 to perform spiral rotary spraying on the mold. Through continuous rotary motion, it can ensure that the mold release agent is evenly coated on the mold surface, avoiding the phenomena of overlap or missed spraying, and is suitable for spraying the mold release agent on molds with complex geometric structures; the spraying method is through rotary and spiral motions, reducing the dead angles existing in the spraying process, improving the lubricity of each corner of the mold, and is especially suitable for molds with multiple depressions or microstructures; the spiral rotary spraying is uniform in spraying, reducing the usage amount of the mold release agent, avoiding material waste, and thus reducing the overall production cost; the uniform mold release agent layer makes the surface of the molded product smoother, reducing the need for post-processing and ensuring the stability of the quality of each batch of products;

[0032] Furthermore, compared with the up-and-down spraying method, the spiral rotary spraying reduces the dead angles during the spraying process, improves the lubricity of every corner of the mold, and is especially suitable for molds with multiple depressions or microstructures.

[0033] Furthermore, the spray head is fixed inside a special fixing frame, which ensures the stability and accuracy during the spraying process. There are fastening screws inside the fixing frame, taking into account the operational convenience and adjustability to adapt to molds of different sizes and shapes.

[0034] Furthermore, the use of a vision positioning camera provides high-precision positioning capabilities for the spiral rotary spraying process. The camera is located on one side of the bottom of the second electric telescopic rod 23 and can capture the position and status of the mold in real time, facilitating the controller to perform forward and reverse rotation control on the first motor 314 and the second motor 324.

[0035] Furthermore, both the first motor 314 and the second motor 324 are electrically connected to the controller through wires. The controller realizes the spiral rotary motion of the spray head fixing frame 33 by controlling the start and stop of the first motor 314 and the second motor 324. This motion mode makes the spraying more uniform, avoids repetition or omission, improves the coverage rate and quality of the release agent. The spiral rotary spraying not only ensures the comprehensiveness of spraying but also improves the production efficiency and reduces product defects and the need for re-spraying caused by improper manual spraying.

[0036] Furthermore, during spraying, the controller receives the visual information from the vision camera at the bottom of the spray head fixing frame 33, automatically calculates and adjusts to control the first motor 314 and the second motor 324 to perform forward and reverse rotation motions. When the first motor 314 rotates, it drives the first driving displacement screw rod 312 to rotate, further driving the first sliding block 313 on the first driving displacement screw rod 312 to slide horizontally back and forth. Since the spray head fixing frame 33 is connected to the first sliding block 313 through the first sliding guide rail 311 of the vertical displacement assembly 32, it further drives the spray head fixing frame 33 to move back and forth horizontally. When the second motor 324 drives the second displacement screw rod 322 to rotate, the second sliding block 323 slides vertically on the second displacement screw rod 322. Since the spray head fixing frame 33 is fixed to the second sliding block 323, it further drives the spray head fixing frame 33 to move vertically. The controller controls the first motor 314 and the second motor 324 to start and stop back and forth to perform a spiral rotary motion on the spray head fixing frame 33, driving the spray head on the spray head fixing frame 33 to perform spiral rotary spraying on the mold.

[0037] The working process of the present utility model:

[0038] When using spraying, fix the spraying nozzle inside the fixing groove of the nozzle fixing frame 33, start the controller and the release agent supply device. The controller controls the operation of the first electric telescopic rod 22 and the second electric telescopic rod 23 according to the visual positioning camera on one side of the bottom of the second electric telescopic rod 23, driving the release agent spiral spraying mechanism 3 to move into the mold after mold opening. The controller receives the visual information from the visual camera at the bottom of the nozzle fixing frame 33, automatically calculates and adjusts to control the first motor 314 and the second motor 324 to perform forward and reverse rotational movements. When the first motor 314 rotates, it drives the first driving displacement screw rod 312 to rotate, further driving the first sliding block 313 on the first driving displacement screw rod 312 to slide horizontally back and forth. Since the nozzle fixing frame 33 is connected to the first sliding block 313 through the first sliding guide rail 311 of the vertical displacement assembly 32, it further drives the nozzle fixing frame 33 to move back and forth horizontally. When the second motor 324 drives the second displacement screw rod 322 to rotate, the second sliding block 323 slides vertically on the second displacement screw rod 322. Since the nozzle fixing frame 33 is fixed to the second sliding block 323, it further drives the nozzle fixing frame 33 to move vertically. The controller controls the first motor 314 and the second motor 324 to start back and forth to perform a spiral rotational movement on the nozzle fixing frame 33, driving the nozzle on the nozzle fixing frame 33 to perform a spiral rotational spraying on the mold.
