[0014] In order to enable the adjusting member to adjust the liquid spraying state, preferably, the connecting channel comprises a second channel connected with the first channel, a third channel in fluid communication with the atomizing liquid channel through the liquid outlet end, and a fourth channel connecting the second channel and the third channel, the second channel is provided with a second through hole and is in fluid communication with the fourth channel through the second through hole, the adjusting member extends into the second channel and forms a joint with the second through hole, and the final liquid spraying state is changed by adjusting the opening size of the joint through the up-down movement of the adjusting member. In this way, the up-down movement of the adjusting member can change the opening size of the joint, when the opening size of the joint is large, the release agent is in a large flow state, when the opening size of the joint is small, the release agent is in a small flow state, and when the adjusting member completely blocks the joint, the joint is closed.

[0015] In order to make the adjusting member change the opening size of the joint by moving up and down, preferably, the adjusting member is in the shape of a rod, the upper end of the adjusting member is exposed outside the shell as an adjusting section, and the lower end of the adjusting member extends into the second flow channel as an adjusting part, the cross section of the adjusting part gradually decreases from top to bottom and can move with the rotation of the adjusting section, thereby at least partially blocking the second through hole to indirectly change the opening size of the joint. Since the cross section of the adjusting part gradually decreases from top to bottom, when the adjusting part is moved downward, the portion of the second through hole blocked by the adjusting part increases, the opening of the joint for the release agent to flow through decreases, thereby reducing the amount of release agent passing through, reducing the ratio of release agent to atomized gas, and making the release agent more fully atomized and the particle size of the atomized release agent smaller; when the adjusting part is moved upward, the portion of the second through hole blocked by the adjusting part decreases, the opening of the joint for the release agent to flow through increases, thereby increasing the amount of release agent passing through, increasing the ratio of release agent to atomized gas, and increasing the particle size of the atomized release agent.

[0016] In order to make the adjusting part move with the rotation of the adjusting section, preferably, the adjusting member further comprises a connecting section connecting the adjusting section and the adjusting part, the connecting section is provided with a threaded part, the shell is provided with an internal thread matched with the threaded part, and the adjusting section in the rotated state can drive the adjusting part to move up and down by means of the matching of the threaded part and the internal thread.

In this way, the valve core has a tendency to always move in the direction of the first through hole under the elastic force of the elastic member and can block the first opening, thereby ensuring that no release agent remains to flow out after the atomizer is closed.

[0019] To enable the head to slide within the first flow channel to open the first through hole, preferably, the housing also includes a control airflow channel coaxially arranged with the valve core. This control airflow channel is in fluid communication with the valve body. By introducing a preset gas into the control airflow channel, the channel acts on the tail section, forcing the valve core to overcome the elastic force of the elastic element and move away from the first through hole, thus opening it. In this way, when the preset gas is introduced into the control airflow channel, a pressure difference is generated on both sides of the tail section within the valve body, pushing the valve core to overcome the elastic force and move away from the first through hole to open it. When the introduction of the preset gas into the control airflow channel stops, the pressure at both ends of the tail section within the valve body tends to be equal, and the elastic element acts on the valve core, causing it to move towards the first through hole and seal the first opening.

[0028] The utility model will be described in further detail below in conjunction with the drawings.

[0029] As Figures 1-6 shown, it is a preferred embodiment of the utility model. The spraying device of the embodiment comprises a mounting rack 8 and a spraying mechanism 9 mounted on the mounting rack 8. The spraying mechanism 9 comprises an atomizer 91 for atomizing the release agent and a spraying arm 92 connected with the atomizer 91 and used for spraying the atomized release agent, the atomizer 91 is internally provided with an atomized liquid flow channel 4 for the atomized release agent to flow out, the spraying arm 92 is distributed with a plurality of spray heads 93, the spray head 93 is internally provided with a spray liquid flow channel for the atomized release agent to spray out, the spraying arm 92 is internally provided with an atomized liquid pipeline, the atomized liquid flow channel 4, the atomized liquid pipeline and the spray liquid flow channel are in fluid communication.

[0030] Referring to Figures 1-4 , the atomizer 91 comprises a shell 1, a liquid flow channel 2, a gas flow channel 3 and an atomized liquid flow channel 4 arranged in the shell 1. The liquid flow channel 2 is provided with an inlet end 2a for the release agent to enter the liquid flow channel 2 and an outlet end 2b for the release agent to flow out, the gas flow channel 3 is provided with an inlet end 3a for the atomized gas to enter the gas flow channel 3 and an outlet end 3b for the atomized gas to spray out, the outlet end 2b of the liquid flow channel 2 and the outlet end 3b of the gas flow channel 3 are in fluid communication with the atomized liquid flow channel 4, the release agent flows out from the outlet end 2b and is atomized by the atomized gas sprayed out from the outlet end 3b before entering the atomized liquid flow channel 4. The upstream of the liquid flow channel 2 and the gas flow channel 3 are both provided with electromagnetic valves for opening or closing the flow channels.

[0031] Due to the fine and uniform mist droplets, the release agent is beneficial to uniform adhesion and good atomization coverage on the surface of the mold, and part of the liquid droplets of the release agent is volatilized before reaching the surface of the mold. Therefore, it is crucial to adjust the spraying state of the release agent according to the viscosity of the release agent and the roughness of the mold surface. The atomizer 91 of the embodiment is provided with an adjusting piece 5, the liquid flow channel 2 comprises a first flow channel 21 and a connecting flow channel 22 connected with the first flow channel 21, the inlet end 2a is arranged in the first flow channel 21, the outlet end 2b is arranged in the connecting flow channel 22, the adjusting piece 5 extends into the connecting flow channel 22, and in the state of adjusting the moving distance of the adjusting piece 5 relative to the connecting flow channel 22 in the up-down direction, at least one of the following spraying states of the release agent can be realized: large flow, small flow or closed.

[0032] Referring to Figure 3The connecting flow channel 22 comprises a second flow channel 221 connected with the first flow channel 21, a third flow channel 222 in fluid communication with the atomizing liquid flow channel 4 via the liquid outlet 2b, and a fourth flow channel 223 connecting the second flow channel 221 and the third flow channel 222. The first flow channel 21 is provided with a first through hole 25 and is in fluid communication with the second flow channel 221 through the first through hole 25. The second flow channel 221 is provided with a second through hole 23 and is in fluid communication with the fourth flow channel 223 through the second through hole 23. The adjusting member 5 extends into the second flow channel 221 and forms a joint 24 with the second through hole 23. The final liquid spraying state is changed by moving the adjusting member 5 up and down to change the opening size of the joint 24. In this embodiment, the adjusting member 5 is in the shape of a rod. The upper end of the adjusting member 5 is exposed outside the shell 1 as an adjusting section 51, and the lower end of the adjusting member 5 extends into the second flow channel 221 as an adjusting part 52. The adjusting section 51 and the adjusting part 52 are connected by a connecting section 53. The connecting section 53 is provided with a threaded part, and the shell 1 is provided with an internal thread matched with the threaded part. The adjusting part 52 can move with the rotation of the adjusting section 51 by matching the threaded part with the internal thread. The cross section of the adjusting part 52 gradually decreases from top to bottom, thereby indirectly changing the opening size of the joint 24 by at least partially blocking the second through hole 23. When the adjusting section 51 is rotated to move the adjusting part 52 downward, the portion of the second through hole 23 blocked by the adjusting part 52 increases, the opening of the joint 24 for the release agent to flow through decreases, the flow amount of the release agent decreases and enters the small flow state, the proportion of the release agent and the atomizing gas decreases, the release agent can be more fully atomized, and the particle size of the atomized release agent decreases. When the adjusting section 51 is rotated to move the adjusting part 52 upward, the portion of the second through hole 23 blocked by the adjusting part 52 decreases, the opening of the joint 24 for the release agent to flow through increases, the flow amount of the release agent increases and enters the large flow state, the proportion of the release agent and the atomizing gas increases, and the particle size of the atomized release agent increases. When the adjusting section 51 is rotated to move the adjusting part 52 downward to completely block the second through hole 23, the liquid flow channel 2 is closed, and the release agent cannot pass through.

[0033] Referring to Figures 4-5The shell 1 of the atomizer 91 of the embodiment further has a switch valve 6 for controlling the opening and closing of the first through hole 25. The switch valve 6 comprises a valve body 61, a valve core 62 and an elastic member 63. The valve core 62 comprises a tail portion 62b arranged in the valve body 61 and a head portion 62a connected with the tail portion 62b and coaxially arranged with the first flow channel 21. The head portion 62a partially extends out of the valve body 61 and can extend into the first flow channel 21. The head portion 62a can slide in the first flow channel 21 to block or open the first through hole 25. The elastic member 63 is arranged in the valve body 61 and abuts against the shell 1 and the tail portion 62b at two ends. The elastic member 63 acts on the valve core 62 and can always make the head portion 62a have a tendency to block the first through hole 25. The shell 1 further has a control gas flow channel 7 coaxially arranged with the valve core 62. The control gas flow channel 7 is in fluid communication with the valve body 61. When preset gas is introduced into the control gas flow channel 7, the control gas flow channel 7 can act on the tail portion 62b and force the valve core 62 to move away from the first through hole 25 against the elastic force of the elastic member 63 and open the first through hole 25. When the preset gas is introduced into the control gas flow channel 7, a gas pressure difference is generated at two sides of the tail portion 62b in the valve body 61, which pushes the valve core 62 to move away from the first through hole 25 against the elastic force and open the first through hole 25. When the introduction of the preset gas into the control gas flow channel 7 is stopped, the gas pressures at two ends of the tail portion 62b in the valve body 61 tend to be consistent. The elastic member 63 acts on the valve core 62 to make the valve core 62 move toward the first through hole 25 and block the first through hole 25. At this time, the liquid flow channel 2 is closed, and the residual release agent is prevented from flowing out of the liquid flow channel 2.

[0034] In summary, the spraying device of the embodiment has the following use states:

[0035] Working state: the control gas flow channel 7 introduces preset gas, which pushes the valve core 62 to move away from the first through hole 25 against the elastic force and open the first through hole 25. The liquid flow channel 2 is in fluid communication. At the same time, the electromagnetic valves upstream of the liquid flow channel 2 and the gas flow channel 3 are opened. The release agent enters the liquid flow channel 2, the atomizing gas enters the gas flow channel 3, the release agent flows out of the liquid outlet 2b, the atomizing gas sprayed from the gas outlet 3b atomizes the release agent, and the atomized release agent enters the atomized liquid flow channel 4, flows through the atomized liquid pipeline, and is sprayed from the liquid flow channel of the spray head 93.

[0036] Closed state: the control gas flow channel 7 stops introducing preset gas, the electromagnetic valves upstream of the gas flow channel 3 and the liquid flow channel 2 are disconnected, the elastic member 63 acts on the valve core 62 to make the valve core 62 move toward the first through hole 25 and block the first through hole 25, and the liquid flow channel 2 is closed to prevent the residual release agent from flowing out.
