[0044] See also Figures 1 to 3 In the first aspect, an anti-sticking mold device 10 is provided in one embodiment of the present application, which is used for a glass molding mold. The glass molding mold includes a plug 20, and a glass liquid guide surface 21 is provided on the plug 20. The anti-sticking mold device includes a purge mechanism 11 and a vibration mechanism 12. The purge mechanism 11 is used to purge and cool the glass liquid guide surface 21; the vibration mechanism 12 is used to be arranged on the plug 20, and the vibration mechanism 12 is used to drive the plug 20 to vibrate.

[0045] The anti-sticking mold device 10 provided in the embodiment of the present application includes a purging mechanism 11 and a vibrating mechanism 12. The purging mechanism 11 is used to purge and cool the glass liquid guiding surface 21 of the plug 20 in the glass forming mold. The vibrating mechanism 12 can be arranged on the plug 20, and the vibrating mechanism 12 is used to drive the plug 20 to vibrate. In this way, during the glass forming process, the vibrating mechanism 12 can be used to drive the plug 20 to vibrate intermittently, so that the glass liquid 40 is separated from the glass liquid guiding surface 21 of the plug 20, thereby preventing the glass liquid 40 from chemically reacting with the glass liquid guiding surface 21 of the plug 20 and the diffusion of elements ... A strong adhesion layer is formed between the glass liquid 40 and the glass liquid guide surface 21 of the plug 20; the purging mechanism 11 can be used to purge and cool the glass liquid guide surface 21 of the plug 20, so that the dust formed by volatilization in the glass liquid 40 can be blown away from the glass liquid guide surface 21, reducing the dust formed by volatilization in the glass liquid 40 from gathering on the glass liquid guide surface 21 of the plug 20, avoiding excessive accumulation of volatile dust and being continuously wrapped by the glass liquid 40, resulting in poor quality of the bottom of the glass; secondly, the temperature of the glass liquid guide surface 21 of the plug 20 can be reduced to prevent the plug 20 from metal fatigue, thereby extending the service life of the glass forming mold. In summary, the present application can effectively reduce the probability of forming an adhesion layer between the glass liquid 40 and the mold, extend the service life of the glass forming mold, and improve the quality and efficiency of glass forming.

[0046] In one embodiment, see Figure 1 and Figure 3 The purging mechanism 11 includes an air pipe 111 and an air supply assembly 112. The air pipe 111 is used to be arranged above the glass liquid guide surface 21 of the plug 20. Both ends of the air pipe 111 are closed. A plurality of air outlet holes 1111 are arranged on the air pipe 111. The plurality of air outlet holes 1111 are used to purge and cool the glass liquid guide surface 21. The air supply assembly 112 is connected to the air pipe 111, and the air supply assembly 112 is used to provide an air source to the air pipe 111.

[0047] In this way, when the purging mechanism 11 is used to purge and cool the glass liquid guide surface 21 of the plug 20, the air supply component 112 provides an air source to the air pipe 111, and the air source in the air pipe 111 is discharged through a plurality of air outlets 1111 to achieve purging and cooling of the glass liquid guide surface 21, and the dust formed by volatilization of the glass liquid 40 is blown away from the glass liquid guide surface 21 in time, thereby reducing the dust formed by volatilization of the glass liquid 40 on the glass liquid guide surface 21 of the plug 20. The accumulation of volatile dust on the glass liquid guide surface 21 of the plug 20 is avoided, and the volatile dust is prevented from accumulating too much and being continuously wrapped by the glass liquid 40, resulting in poor quality of the bottom of the glass. At the same time, the temperature of the glass liquid guide surface 21 of the plug 20 can be reduced to prevent metal fatigue of the plug 20, thereby extending the service life of the glass forming mold.

[0048] It should be noted that the longitudinal section of the glass liquid guide surface 21 is a concave arc shape, and can also be an inclined surface. When the longitudinal section of the glass liquid guide surface 21 is a concave arc shape, the air pipe 111 can be an arc-shaped pipe adapted to the glass liquid guide surface 21, so that the glass liquid guide surface 21 can be fully cooled, the plug 20 can be prevented from metal fatigue, and the service life of the plug 20 can be extended, thereby extending the service life of the glass forming mold. When the longitudinal section of the glass liquid guide surface 21 is an inclined surface, the air pipe 111 can be a straight pipe.

[0049] For a specific example, see Figure 1 The number of the air outlet holes 1111 can be 1 to 20, and the diameter of the air outlet holes 1111 is 0.1 to 1 mm; the air pipe 111 can be a high temperature resistant pipe such as a stainless steel pipe or a copper pipe.

[0050] In a specific example, the air pipe 111 can be fixed above the glass liquid guiding surface 21 of the plug 20 by a fixing component such as a fixing clamp.

[0051] In a specific example, the air supply component 112 may include an air compressor configured to provide compressed air to the air source.

[0052] In one embodiment, see Figure 1 , multiple air outlet holes 1111 are arranged at intervals along the extension direction of the air pipe 111; the air pipe 111 is also provided with an air inlet pipe 1112, which is arranged in the middle of the air pipe 111 and communicated with the air pipe 111, and the air inlet pipe 1112 is connected to the air supply component 112.

[0053] In this way, by arranging multiple air outlet holes 1111 at intervals along the extension direction of the air pipe 111 and arranging the air inlet pipe 1112 in the middle of the air pipe 111, the connection between the air pipe 111 and the air supply assembly 112 can be facilitated, and the gas source can reach each air outlet hole 1111, thereby ensuring the air output at each air outlet hole 1111, so as to blow away the dust formed by volatilization of the glass liquid 40 from the glass liquid guide surface 21, reduce the dust formed by volatilization of the glass liquid 40 on the glass liquid guide surface 21 of the plug 20, avoid excessive accumulation of volatile dust and being continuously wrapped by the glass liquid 40 to cause poor quality of the bottom of the glass, and at the same time effectively reduce the temperature of the glass liquid guide surface 21 of the plug 20, thereby extending the service life of the plug 20.

[0054] In one embodiment, see Figure 1 , Figure 3 and Figure 4 The vibration mechanism 12 includes a vibrator, which may be an electric vibrator or a pneumatic vibrator 121. Preferably, the vibrator may be a pneumatic vibrator 121, which is connected to an air supply assembly 112. The air supply assembly 112 is also used to provide an air source to the pneumatic vibrator 121 so that the pneumatic vibrator 121 generates a vibration force.

[0055] In this way, the same air supply assembly 112 can be used to provide air source to the pneumatic vibrator 121 and the air pipe 111, simplifying the composition of the anti-sticking mold device 10, facilitating the installation of the anti-sticking mold device 10, reducing the volume of the anti-sticking mold device 10, and reducing the cost of the anti-sticking mold device 10.

[0056] In a specific example, the pneumatic vibrator 121 may be a pneumatic hammer.

[0057] In one embodiment, see Figure 1 and Figure 3 , and also includes a three-way pipe 13, through which the air supply component 112 is connected to the air pipe 111 and the pneumatic vibrator 121.

[0058] In this way, the connection between the air supply assembly 112 , the air pipe 111 and the pneumatic vibrator 121 can be facilitated through the three-way pipe 13 , thereby assembling the anti-sticking mold device 10 .

[0059] In one embodiment, see Figure 4, also includes a first control valve 141 and a second control valve 142; the first control valve 141 is arranged between the air supply component 112 and the air pipe 111; the first control valve 141 is used to control the gas flow of the air pipe 111 and the connection and disconnection between the air pipe 111 and the air supply component 112; the second control valve 142 is arranged between the air supply component 112 and the pneumatic vibrator 121; the second control valve 142 is used to control the gas flow of the pneumatic vibrator 121 and the connection and disconnection between the pneumatic vibrator 121 and the air supply component 112.

[0060] In this way, through the first control valve 141 and the second control valve 142, the intermittent operation of the air pipe 111 and the pneumatic vibrator 121 can be conveniently controlled, and the gas flow of the air pipe 111 and the gas flow of the pneumatic vibrator 121 can be conveniently adjusted, so that the purge and cooling rate of the air pipe 111 can be conveniently adjusted, and the vibration frequency and amplitude of the pneumatic vibrator 121 can be conveniently adjusted, so that the vibration frequency and amplitude of the plug 20 can be adjusted, so that the anti-sticking mold device 10 can be suitable for glass liquid 40 with different viscosities.

[0061] In a specific example, both the first control valve 141 and the second control valve 142 may be solenoid valves.

[0062] In one embodiment, see Figure 4 , also includes a first timer 151, a second timer 152 and a controller 16; the controller 16 is electrically connected to the first timer 151, the second timer 152, the first control valve 141 and the second control valve 142; the first timer 151 is used to time the first working time and the first non-working time of the air pipe 111; the second timer 152 is used to time the second working time and the second non-working time of the purge mechanism 11; the controller 16 is used to control the switch of the first control valve 141 according to the information of the first timer 151; the controller 16 is also used to control the switch of the second control valve 142 according to the information of the second timer 152.

[0063] Thus, during the glass forming process, the controller 16 controls the first control valve 141 to open, and the multiple air outlets 1111 on the air pipe 111 purge and cool the glass liquid guide surface 21, and the first timer 151 starts timing; the controller 16 controls the second control valve 142 to open, and the pneumatic vibrator 121 drives the plug 20 to vibrate, and the second timer 152 starts timing; when the time recorded by the first timer 151 reaches the first working time, the controller 16 controls the first control valve 141 to close, and at the same time, the first timer 151 restarts timing; when the time recorded by the second timer 152 reaches the second working time , the controller 16 controls the second control valve 142 to close, and at the same time, the second timer 152 restarts timing; when the time recorded by the first timer 151 reaches the first non-working time, the controller 16 controls the first control valve 141 to open, and the multiple air outlets 1111 on the air pipe 111 again purge and cool the glass liquid guide surface 21, and the first timer 151 restarts timing; when the time recorded by the second timer 152 reaches the second non-working time, the controller 16 controls the second control valve 142 to open, and the pneumatic vibrator 121 drives the plug 20 to vibrate again, and the second timer 152 restarts timing. During the entire glass forming process, the intermittent operation of the air pipe 111 and the pneumatic vibrator 121 is achieved through the cooperation of the first timer 151, the second timer 152 and the controller 16, thereby effectively reducing the probability of forming an adhesion layer between the glass liquid 40 and the mold, extending the service life of the glass forming mold, and improving the glass forming quality and efficiency.

[0064] It should be noted that the first working duration may be equal to the second working duration, and the first non-working duration may be equal to the second non-working duration. In this way, the controller 16 can control the first control valve 141 and the second control valve 142 to switch synchronously.

[0065] In one embodiment, see Figure 4 , also includes a first flow meter 171 and a second flow meter 172. The first flow meter 171 is arranged between the air supply component 112 and the air pipe 111, and the first flow meter 171 is used to monitor the gas flow of the air pipe 111; the second flow meter 172 is arranged between the air supply component 112 and the pneumatic vibrator 121, and the second flow meter 172 is used to monitor the gas flow of the pneumatic vibrator 121.

[0066] Thus, by providing the first flow meter 171 and the second flow meter 172 , the gas flow of the air pipe 111 and the gas flow of the pneumatic vibrator 121 can be conveniently monitored, and the gas flow of the air pipe 111 and the gas flow of the pneumatic vibrator 121 can be conveniently adjusted.

[0072] The molten glass liquid 40 flows out from the discharge pipe 30 and flows along the glass liquid guide surface 21 of the plug 20 toward the molding groove;

[0073] The purging mechanism 11 is used to purge and cool the glass liquid guide surface 21 at intervals of a first preset time and for a second preset time, so as to clean the volatile dust on the glass liquid guide surface 21 and reduce the temperature of the glass liquid guide surface 21; the vibrating mechanism 12 is used to drive the plug 20 to vibrate at intervals of a third preset time and for a fourth preset time, so as to separate the glass liquid 40 from the glass liquid guide surface 21 of the plug 20, so as to prevent the glass liquid 40 from chemically reacting with the glass liquid guide surface 21 of the plug 20 and preventing the elements from diffusing to form an adhesion layer;

In this way, the volatile dust on the glass liquid guide surface 21 can be cleaned, and the dust formed by the volatilization of the glass liquid 40 can be reduced from gathering on the glass liquid guide surface 21 of the plug 20, so as to avoid excessive accumulation of volatile dust and continuous wrapping by the glass liquid 40, resulting in poor quality of the bottom of the glass. At the same time, the temperature of the glass liquid guide surface 21 can be reduced to prevent the plug 20 from metal fatigue, thereby extending the plug 20. 20, and thus the service life of the glass forming mold; the vibration mechanism 12 drives the plug 20 to vibrate at intervals of the third preset time and continues for a fourth preset time to separate the glass liquid 40 from the glass liquid guide surface 21 of the plug 20, thereby preventing the glass liquid 40 from chemically reacting with the glass liquid guide surface 21 of the plug 20 and preventing elements from diffusing to form an adhesion layer; in summary, the glass forming method of the present application can effectively reduce the probability of forming an adhesion layer between the glass liquid 40 and the mold, improve the quality and efficiency of glass forming, and at the same time, extend the service life of the glass forming mold.

[0076] It is understandable that the purge mechanism 11 can operate synchronously with the vibration mechanism 12, that is, the purge mechanism 11 and the vibration mechanism 12 can be started and stopped synchronously; the first preset time length can be equal to the third preset time length, and the second preset time length can be equal to the fourth preset time length.
