[0039] Embodiment:

[0040] To prevent the materials in the vacuum chamber 300 from leaking and being unable to be quickly cleaned, the leaking materials are discharged through the discharge valve 100. In this application, the power generated by the downward flow of the materials leaking from the vacuum chamber 300 mainly enables the sealing ball 140 to move downward against the elastic force of the elastic member 160, so that the sealing ball 140 releases the blockage of the outlet of the discharge channel 120, allowing the materials from the vacuum chamber 300 to automatically fall, realizing the function of automatic material discharge when leakage occurs; and during the downward movement of the sealing ball 140, it touches the trigger switch 130, thereby forming a circuit for the trigger switch 130 and transmitting an electrical signal to an external controller. The external controller then controls the equipment that supplies materials to the vacuum chamber 300 to stop, halting the supply of materials to the vacuum chamber 300, thereby reducing material waste and enabling the materials in the vacuum chamber 300 to be quickly discharged, facilitating the cleaning of the vacuum chamber 300.

[0041] The discharge valve 100 provided in this application includes a valve body 110, a discharge channel 120, a trigger switch 130, a sealing ball 140, and an elastic member 160. Among them, the discharge channel 120 is opened inside the valve body 110, and the discharge channel 120 is used for discharging materials; the trigger switch 130 is located in the discharge channel 120; the sealing ball 140 is located in the discharge channel 120, and the sealing ball 140 is used to trigger the trigger switch 130; the elastic member 160 is located inside the discharge channel 120, and the end of the elastic member 160 abuts against the outer surface of the sealing ball 140. The elastic member 160 is used to drive the sealing ball 140 to block the outlet of the discharge channel 120.

[0042] Specifically, referring to Figure 1 As shown, in the initial state, under the elastic force of the elastic member 160, the sealing ball 140 blocks the outlet of the discharge channel 120. However, when the vacuum chamber 300 leaks, the materials from the vacuum chamber 300 will flow into the discharge channel 120. The materials flowing into the discharge channel 120 will cause the sealing ball 140 to move downward against the elastic force of the elastic member 160, thereby releasing the blockage of the outlet of the discharge channel 120. During the downward movement of the sealing ball 140, it touches the trigger switch 130, so that the trigger switch 130 forms a signal circuit. After the trigger switch 130 forms a circuit, the signal is transmitted to an external controller through a wire 172. The controller controls the equipment that supplies materials to the vacuum chamber 300 to stop supplying materials, reducing material waste.

[0043] In this embodiment, the elastic member 160 can be a spring, specifically a compression spring.

[0044] The discharge channel 120 includes a first channel 121 and a second channel 122 opened in the valve body 110. The first channel 121 is communicated with the second channel 122, and the inner diameter at the communicating position of the first channel 121 and the second channel 122 gradually increases in the direction close to the second channel 122.

[0045] The diameter of the sealing ball 140 is d1, the diameter of the first channel 121 is d2; the diameter of the second channel 122 is d3; where d1, d2 and d3 satisfy the following relationship: d2 < d1 < d3.

[0046] Continue to refer to Figure 1 , in this embodiment, the first channel 121 and the second channel 122 are combined to form a channel for discharging the leakage material. In order to enable the sealing ball 140 to block the channel for material discharge, the inner diameter of the second channel 122 is made larger than that of the first channel 121, and the first channel 121 is communicated with the vacuum chamber 300, that is, in the height direction, the first channel 121 is located above the second channel 122.

[0047] Specifically, the diameter at the communicating position of the first channel 121 and the second channel 122 gradually increases in the direction of the second channel 122. Further, the diameter of the sealing ball 140 is larger than the inner diameter of the first channel 121, then the diameter of the sealing ball 140 is smaller than the inner diameter of the second channel 122, that is, it satisfies the relationship of d2 < d1 < d3. The purpose of the sealing ball 140 satisfying this relationship is that only when the diameter of the sealing ball 140 is larger than the inner diameter of the first channel 121 can the outlet of the first channel 121 be blocked.

[0048] It should be noted here that since the vacuum chamber 300 needs to be evacuated during operation, it is necessary to block the first channel 121 through the sealing ball 140 to prevent external gas from entering the vacuum chamber 300 through the first channel 121.

[0049] In this embodiment, the connection between the first channel 121 and the second channel 122 is funnel-shaped. When blocking, the sealing ball 140 is located in this funnel area. For details, refer to Figure 1 as shown.

[0050] An installation seat 150 is placed and installed in the second channel 122. The trigger switch 130 is arranged on the installation seat 150. The elastic member 160 is arranged on the installation seat 150. The trigger switch 130 is located inside the elastic member 160. The sealing ball 140 is located above the installation seat 150.

[0051] Refer to Figure 1As shown, the mounting base 150 has certain holes, enabling the material from the discharge channel 120 to flow downward through the holes. The mounting base 150 will be elaborated in detail hereinafter and will not be elaborated here in detail.

[0052] The mounting base 150 is mounted on the stepped surface in the second material channel 122. The stepped surface can be the end face of a connecting pipe with an external thread. Specifically, the connecting pipe is threadedly connected to the inside of the second material channel 122, and the end face of the connecting pipe is located in the second material channel 122, thus forming a stepped surface for the mounting base 150 to be mounted. Further, since the connecting pipe is hollow, the material from the first material channel 121 enters the second material channel 122 and then passes through the holes in the mounting base 150 and enters the connecting pipe, enabling the material to flow out smoothly.

[0053] The trigger switch 130 and the elastic member 160 are both located on the mounting base 150. Among them, the trigger switch 130 is located inside the elastic member 160. In the initial state, under the elastic support of the elastic member 160, the sealing ball 140 does not contact the trigger switch 130, that is, it will not trigger the trigger switch 130 to form a circuit; when the sealing ball 140 moves downward overcoming the elastic force of the elastic member 160, after the sealing ball 140 descends a certain distance, it will contact the trigger switch 130, causing the trigger switch 130 to form a signal circuit. At this time, the controller can receive the signal that the trigger switch 130 forms a circuit. At this time, it can be determined that the vacuum chamber 300 has leaked. Next, the controller can automatically control the equipment that supplies materials to the vacuum chamber 300 to stop or cut off the feeding line.

[0054] The mounting base 150 includes a mounting plate 151. The mounting plate 151 is provided with a plurality of through holes 152 penetrating therethrough. A sleeve 153 is provided on the mounting plate 151. A cushion block 154 is provided inside the sleeve 153. The elastic member 160 is located on the sleeve 153. The trigger switch 130 is located on the cushion block 154.

[0055] Refer to Figure 2 As shown, the mounting plate 151 is mounted on the corresponding stepped surface. Since the through holes 152 are provided on the mounting plate 151, the second material channel 122 is communicated with the outside through the through holes 152; enabling the material to be discharged.

[0056] Continue to refer to Figure 2 , setting the sleeve 153 on the mounting plate 151 can mount the elastic member 160. The end of the elastic member 160 is located on the upper surface of the sleeve 153. And the cushion block 154 in the sleeve 153 can, on the one hand, limit the elastic member 160 to prevent the elastic member 160 from moving in position, and on the other hand, support the trigger switch 130 to enable the trigger switch 130 to reach a certain height.

[0057] Specifically, the spacer block 154 is at least partially located in the elastic member 160 to limit the elastic member 160; in the initial state, the trigger switch 130 is located in the elastic member 160, and the trigger position of the trigger switch 130 is lower than the upper end surface of the elastic member 160. Only when an external leakage force acts on the sealing ball 140 will the elastic member 160 contract, and the sealing ball 140 moves downward to contact and trigger the trigger switch 130.

[0058] In this embodiment, in order to install the trigger switch 130 in the elastic member 160, the trigger switch 130 can be a tactile switch, or other types of switches with a small volume that can be located in the elastic member 160. The specific types, models, and sizes of the switches are not limited here; correspondingly, the models, sizes, etc. of the elastic member 160 are also not restricted, as long as the functional requirements can be met.

[0059] A communication structure 170 is provided in the valve body 110. The communication structure 170 includes a connection hole 171 opened on the valve body 110. The connection hole 171 communicates with the discharge channel 120. The trigger switch 130 is connected to a wire 172. The wire 172 passes through the connection hole 171, and a sealing is provided between the wire 172 and the wire 172.

[0060] Refer to Figure 1 As shown, in order to enable the trigger switch 130 to conduct to form a loop and transmit the signal to an external controller, a connection hole 171 is opened on the valve body 110 for the wire 172 to pass through. Through the wire 172, the signal of the trigger switch 130 being conducted can be transmitted to the external controller. Specifically, in order to prevent the material from flowing out of the gap between the wire 172 and the connection hole 171, the gap can be sealed with sealant after the wire 172 passes through, so as to prevent the material from leaking out of the connection hole 171.

[0061] A sealing structure 180 is provided on the mounting surface of the valve body 110. The sealing structure 180 includes a mounting groove 181 opened on the mounting surface of the valve body 110, and a sealing ring 182 is provided in the mounting groove 181.

[0062] Refer to Figure 1 As shown, in order to prevent the material from leaking at the connection between the valve body 110 and the vacuum chamber 300, the connection is sealed through the sealing structure 180. Specifically, a sealing ring 182 is provided in the mounting groove 181 opened on the connection surface between the valve body 110 and the vacuum chamber 300, so as to achieve the sealing effect.

[0063] Exemplarily, the sealing ring 182 can be an O-ring, V-ring, U-ring, etc., which can be selected according to actual needs. Correspondingly, the shape of the installation groove 181 should also be adapted to the shape of the sealing ring 182. In this embodiment, the sealing ring 182 is selected as an O-ring.

[0064] A ball valve 200 is fixedly installed on the valve body 110, and the ball valve 200 is communicated with the outlet of the discharge channel 120.

[0065] Refer to Figure 1 As shown, since the vacuum chamber 300 needs to be evacuated, it is necessary to block the first material channel 121 to prevent external air from entering the vacuum chamber 300 through the first material channel 121 and the second material channel 122 to form a passage. Since the sealing ball 140 blocks the first material channel 121 by the elastic force of the elastic member 160, in order to prevent the insufficient elastic force of the elastic member 160 from causing the sealing ball 140 to fail to block the outlet of the first material channel 121 and resulting in the inability to evacuate the vacuum chamber 300, for safety reasons, a ball valve 200 is provided at the outlet position of the second material channel 122; if the sealing ball 140 fails, the ball valve 200 blocks the entire discharge channel 120 to ensure that the vacuum chamber 300 can be evacuated normally.

[0066] Exemplarily, the stepped surface on which the mounting seat 150 is mounted can also be formed at the connection between the ball valve 200 and the valve body 110.

[0067] The present application provides a pouring device, which includes a vacuum chamber 300, and any one of the above-mentioned discharge valves 100 is installed on the vacuum chamber 300; it further includes a feeding hose 600, a frame 400 and a lifting module 700. Among them, the feeding hose 600 is connected to the vacuum chamber 300, the feeding hose 600 is used to provide pouring materials for the vacuum chamber 300, the frame 400 defines a receiving chamber 500, the feeding hose 600 passes through the receiving chamber 500, the lifting module 700 is fixedly installed on the frame 400, and a pressing plate 800 is installed at the telescopic end of the lifting module 700, and the pressing plate 800 is located in the receiving chamber 500.

[0068] The frame 400 includes a bottom plate 410, a connecting plate 420 is fixedly installed on the surface of the bottom plate 410, and a top plate 430 is fixedly installed at the end of the connecting plate 420 away from the bottom plate direction. The bottom plate 410, the connecting plate 420 and the top plate 430 define the receiving chamber 500.

[0069] It should be noted here that the pouring equipment in this application mainly relates to the VPG (Vacuum Pressure Gel Casting) pouring process, that is, the equipment using the vacuum pressure gel casting process. In other embodiments, it can also be other injection molding or pouring equipment. The specific types and categories of the equipment are not limited here as long as the discharge valve in this application can be used.

[0070] Refer to Figure 3 and Figure 4 As shown, after the trigger switch 130 is triggered, in order to cut off the continuous feeding of the feeding pipeline to the vacuum chamber 300, the controller controls the lifting module 700 to drive the pressing plate 800 to move downward. The pressing plate 800 presses down the feeding hose 600 to deform it, so that the feeding hose 600 stops feeding the vacuum chamber 300, thereby cutting off the continuous feeding.

[0071] Exemplarily, the lifting module 700 can be a component capable of linear drive such as a cylinder, an oil cylinder, an electric cylinder, a motor screw module, etc. In this embodiment, the lifting module 700 is selected as a cylinder; in practice, it can be selected according to needs and is not limited here.

[0072] The working process of this application is as follows: When the material in the vacuum chamber 300 leaks, the material will leak into the first material channel 121, and then the sealing ball 140 will overcome the elastic force of the elastic member 160 and drop, releasing the blockage of the outlet of the first material channel 121. The material will leak out through the pipeline formed by the first material channel 121 and the second material channel 122, discharging the material in the vacuum chamber 300; after the sealing ball 140 drops to a certain distance, it will contact the trigger switch 130 and trigger the trigger switch 130 to form a circuit to generate a signal. The generated signal is transmitted to the external controller through the wire 172. The controller controls the lifting module 700 to start and drive the pressing plate 800 to move downward. The pressing plate 800 presses and cuts off the passage of the feeding hose 600, so that the feeding hose 600 stops feeding the vacuum chamber 300, reducing the waste of materials.
