Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Please see Figures 1 to 4 ,in, Figure 1 This is a schematic diagram of the overall structure of this utility model. Figure 2 This is a side view of the entire utility model. Figure 3 This is a partial structural schematic diagram of the present invention. Figure 4 This is a partial structural schematic diagram of the translation mechanism of this utility model.

[0020] This utility model provides a linkage-type sprayer for die casting, including an air control box 1, a linkage mechanism, a translation mechanism, and an atomizing mechanism. The atomizing mechanism includes a lower housing 3, a flow divider 4, multiple solenoid valves 5, two air control valves 6, multiple atomizing nozzles 7, and multiple quick drain valves 8. The lower housing 3 is fixedly connected to the upper end of the air control box 1. The linkage mechanism is disposed on the air control box 1, the flow divider 4 is disposed on the linkage mechanism, the multiple solenoid valves 5 are respectively disposed inside the air control box 1, the two air control valves 6 are respectively disposed inside the lower housing 3, the multiple atomizing nozzles 7 are respectively disposed on the flow divider 4, and the multiple quick drain valves 8 are respectively disposed inside the air control box 1.

[0021] In this embodiment, the multiple solenoid valves 5 are: one each of a moving mold spray and a moving mold blowing two-way solenoid valve 5, and one each of a stationary mold spray and a stationary mold blowing two-way solenoid valve 5. The two pneumatic control valves 6 are: one for releasing agent into the moving and stationary molds, and one for cleaning air into the moving and stationary molds. The two pneumatic control valves 6 are controlled to open and close by two two-position five-way valves. Switching between cleaning air and releasing agent is possible. During atomized demolding, spraying and demolding are performed through multiple atomizing nozzles 7. The multiple quick-drain valves 8 prevent water from entering the two-position five-way valves and damaging them if the air source or the atomizing nozzles 7 are damaged. Therefore, the device uses multiple pipes with increased inner diameters, resulting in stable air volume, low pressure, and strong bursting force during spraying. Due to the excellent atomization effect, the cost of releasing agent is reduced by half, and the operating speed and service life are doubled. Because of the good atomization effect, less releasing agent is used.

[0022] Furthermore, the linkage mechanism includes a servo motor 9, a drive arm 10, an arm adapter flange 11, a support arm 12, a bearing flange 13, and a connecting unit. The servo motor 9 is disposed on the inner wall of the pneumatic control box 1. The arm adapter flange 11 is fixedly connected to the output end of the servo motor 9 and rotatably connected to the pneumatic control box 1. The drive arm 10 is fixedly connected to the arm adapter flange 11.

The connecting unit includes a cable connector 14, a cable chain bend 15, a cable chain connecting flange 16, a horizontal arm 17, a nozzle connecting plate 18, a nozzle adapter plate 19, a nozzle connecting pipe 20, and a nozzle connecting pipe transition flange 21. The cable connector 14 is connected to the upper end of the air control box 1. One end of the cable chain bend 15 is connected to the cable connector 14, and the other end of the cable chain bend 15 is fixedly connected to the cable chain connecting flange 16. One end of the horizontal arm 17 is fixedly connected to the cable chain connecting flange 16, and the other end of the horizontal arm 17 is fixedly connected to the nozzle connecting plate 18. The nozzle adapter plate 19 is fixedly connected to the nozzle connecting plate 18, and the nozzle connecting pipe 20 is fixedly connected to the nozzle adapter plate 19. The nozzle connecting pipe transition flange 21 is connected to the upper end of the diverter plate 4.

[0023] In this embodiment, the output end of the servo motor 9 drives the arm adapter flange 11 to rotate, which in turn drives the drive arm 10 to rotate, which in turn drives the horizontal arm 17 to move, which in turn drives the diverter plate 4 to move. When the horizontal arm 17 rotates, it drives the support arm 12 and the bearing flange 13 to rotate, thereby improving the balance and stability of the horizontal arm 17 when rotating. When the horizontal arm 17 moves, it drives the cable chain bending part 15 to move. The atomized liquid passes through the cable chain head 14, the cable chain bending part 15, and then enters the horizontal arm 17, the nozzle adapter plate 19 and the nozzle connecting pipe 20. Then it enters the diverter pipe from the nozzle connecting pipe transition flange 21 and is then sprayed out from multiple atomizing nozzles.

[0024] Further, the translation mechanism includes a fixed plate 22, a cover plate 23, two U-shaped plates 24, a base plate 25, a motor cover 26, a drive motor 27, a threaded rod 28, a nut 29, a guide plate 30, two guide rails 31, multiple sliders 32, a slide cover plate 33, a mounting plate 34, and a water receiving plate 35. The fixed plate 22 is fixedly connected to the upper end of the pneumatic control box 1. The two U-shaped plates 24 are respectively fixedly connected to the upper end of the fixed plate 22. The base plate 25 is located inside the cover plate 23 and is fixedly connected to the two U-shaped plates 24. The slide cover plate 33 is disposed on the upper end of the cover plate 23 and is located on the upper end of the base plate 25. The drive motor 27 is disposed outside the slide cover plate 33, the motor cover 26 is sleeved on the outside of the drive motor 27, the threaded rod 28 is rotatably connected to the inside of the cover plate 23, the nut 29 is adapted to the threaded rod 28, the guide plate 30 is fixedly connected to the nut 29, the upper end of the guide plate 30 is fixedly connected to the base plate 25, two guide rails 31 are respectively disposed inside the cover plate 23, multiple sliders 32 are respectively fixedly connected to the base plate 25, and multiple sliders 32 are respectively slidably adapted to the guide rails 31. The output end of the drive motor 27 passes through the slide cover plate 33 and is fixedly connected to the threaded rod 28.

[0025] In this embodiment, the output end of the drive motor 27 drives the threaded rod 28 to rotate, causing the nut 29 to engage with the threaded rod 28. The nut 29 is fixed on the guide plate 30, and the guide plate 30 is fixed on the base plate 25. Through the cooperation of multiple sliders 32 and two guide rails 31, the base plate 25 is limited to lateral movement. The rotation of the base plate 25, the slide cover plate 33, and the cover plate 23 is changed to sliding along the two U-shaped plates 24. The mounting edge facilitates the installation of the device.

[0026] Furthermore, the die-casting linkage sprayer also includes a door 2, which is rotatably connected to the air control box 1. The water receiving plate 35 is fixedly connected to the outer wall of the air control box 1 and is located below the diverter plate 4. The mounting plate 34 is fixedly connected to the upper end of the slide cover plate 33.

[0027] In this embodiment, by opening the door 2, the interior of the air control box 1 can be inspected and maintained. The machine is installed on the fixed mold surface of the die-casting machine. When the die-casting machine opens the mold, upon receiving an action signal, the linkage-type sprayer arm descends from the standby position into the mold. When the flow divider 4 reaches the mold position, the corresponding solenoid valve 5 controlled by the water-air circuit opens. The atomizing nozzle 7 mixes the release agent and compressed air at the nozzle opening to form a mist, generating pressure to diffuse and spray onto the mold surface, forming a release coating and cooling the mold to achieve a constant temperature. During spraying, floating spraying and fixed-point spraying can be performed according to the mold spraying point. Single-point or multi-point spraying can be performed simultaneously. After spraying is completed, similarly, a final step is performed by opening the moving mold blowing and fixed mold blowing solenoid valves 5 to dry the mold surface, then returning to the origin until the next mold opening.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
