[0022] The following further elaborates on this application Figure 1-3 in conjunction with the attached drawings.

[0023] An embodiment of this application discloses a spraying machine for the surface of an injection mold. Refer to Figure 1-3 A spraying machine for the surface of an injection mold includes an electric conveying roller rack 1. The mold 402 is conveyed through the electric conveying roller rack 1.

A mold 402 is installed on the C-shaped loading platform 401. The C-shaped loading platform 401 is conveyed by the electric conveying roller rack 1 to move, and the mold 402 is sent into the chamber body 201. The C-shaped loading platform 401 fills the material opening of the chamber body 201 to form a protective space to prevent the spraying waste gas from diffusing outward. A negative pressure treatment assembly 5 and a spraying assembly 6 are also installed on the chamber body 201. The spraying waste gas in the chamber body 201 and the impurities on the mold 402 are removed through the negative pressure treatment assembly 5. The surface of the mold 402 is sprayed through the spraying assembly 6. A positioning assembly 7 is installed on one side of the chamber body 201 for discharging materials to intercept the C-shaped loading platform 401 to prevent the C-shaped loading platform 401 from moving during spraying;

[0024] By adopting the above technical solution, the C-shaped loading platform 401 carrying the mold 402 is conveyed into the chamber body 201 through the electric conveying roller rack 1. The C-shaped loading platform 401 is intercepted by the positioning assembly 7, and the C-shaped loading platform 401 stops moving. The C-shaped loading platform 401 fills the material opening of the chamber body 201 to form a protective space. The spraying waste gas is restricted from diffusing outward through the protective space. The spraying waste gas in the chamber body 201 and the impurities on the mold 402 are removed through the negative pressure treatment assembly 5. The surface of the mold 402 is sprayed through the spraying assembly 6. After spraying, the positioning assembly 7 releases the interception, and the C-shaped loading platform 401 can continue to convey the mold 402 to move into the drying process.

[0025] Refer to Figure 1 As shown in Figure 1 , the electric conveying roller rack 1 is composed of a support frame, a plurality of conveying rollers, and a motor. The plurality of conveying rollers are传动连接 by a chain drive unit, and the roller is driven by the motor to rotate, so as to实现 the conveying of the U-shaped loading platform 401.

[0026] Refer to Figure 3 As shown in Figure 3 , an inductor 202 is installed at the material outlet of the bin body 201. The inductor 202 is used to detect whether the U-shaped loading platform 401 reaches the specified position, so as to实现 the operation of controlling the positioning component 7 to intercept the U-shaped loading platform 401. The inductor 202 can be selected as a photoelectric sensor, an ultrasonic sensor, etc. according to needs.

[0027] Refer to Figure 1 As shown in Figure 1 , the negative pressure treatment component 5 includes an air extraction pump 501 installed on the bin body 201. An air purification box 502 is installed on the air extraction pump 501. The air purification box 502 is composed of a box body, a filter, and an air inlet and an air outlet. The air outlet is连通 with the air extraction pump 501. The air inlet is connected with a guide pipe 503. The end of the guide pipe 503 passes through the bin body 201 and is connected with a negative pressure suction pipe 504. The filter is made of high-efficiency filter materials, such as activated carbon filters, HEPA filters, etc., to remove impurities and harmful substances in the air.

[0028] Refer to Figure 3 As shown in Figure 3 , the spraying component 6 includes a storage tank 601 and a material extraction pump 602 installed on the U-shaped loading platform 401. Two guide pipes 603 are installed on the material extraction pump 602. One guide pipe 603 is连通 with the storage tank 601. The end of one guide pipe 603 passes through the bin body 201 and is connected with a spraying pipe 604. The PTFE coating material is stored in the storage tank 601, and the PTFE coating can be sprayed onto the mold 402 through the spraying pipe 604. Both the guide pipe 603 and the guide pipe 503 are telescopic hoses.

[0029] Refer to Figure 2 As shown in Figure 2 , the moving component 3 includes an X-axis feeding system 301. A spraying support 302 and a telescopic cylinder 303 are installed at the movable end of the X-axis feeding system 301. The spraying pipe 604 is installed on the spraying support 302. A suction support 304 is installed at the lower end of the telescopic cylinder 303. The negative pressure suction pipe 504 is installed on the suction support 304. The height of the suction support 304 is adjusted by the telescopic cylinder 303 to实现 the change of the height of the negative pressure suction pipe 504. It can move along the upper surface of the mold 402 before spraying to清除 surface impurities and improve the spraying effect. During spraying, the negative pressure suction pipe 504 is reset and moved to the spraying support 302 to avoid affecting the spraying effect. When cleaning waste gas, it can directly suck and remove without telescoping. The X-axis feeding system 301 is composed of a guide rail, a slider, a control motor, and a control system.

[0030] Reference Figure 2 Figure 2 , the positioning assembly 7 includes an intercepting cylinder 701 installed on the electric conveying roller frame 1. A connecting block 702 is connected to the end of the intercepting cylinder 701. The connecting block 702 is driven to move by the telescopic movement of the intercepting cylinder 701, and the U-shaped loading platform 401 is intercepted by the connecting block 702.

[0031] The implementation principle of an injection mold surface spraying machine according to an embodiment of the present application is as follows: Place the injection mold 402 to be sprayed on the U-shaped loading platform 401 and ensure that the mold is fixed stably. Start the electric conveying roller frame 1 to make the loading platform carrying the mold enter the chamber 201 of the spraying chamber 2. When the loading platform 401 and the mold 402 move to a predetermined position, the sensor 202 emits a signal to control the telescopic movement of the intercepting cylinder 701, driving the connecting block 702 to move and intercepting the loading platform 401 to ensure the stable position of the mold 402 during the spraying process. Before spraying, adjust the positions of the spraying bracket 302 and the suction bracket 304 through the X-axis feeding system 301. The telescopic cylinder 303 works to adjust the height of the negative pressure suction pipe 504 on the suction bracket 304 to make it fit the upper surface of the mold 402 to remove impurities on the surface. The negative pressure treatment assembly 5 is started, and the air extraction pump 501 extracts impurities on the upper surface of the mold 402 through the air guide pipe 503 and the negative pressure suction pipe 504. During spraying, the telescopic cylinder 303 drives the negative pressure suction pipe 504 to reach the highest position to suck out the waste gas in the chamber 201, which is discharged after being processed by the air purification box 502. At this time, the spraying assembly 6 starts to work. The PTFE coating in the storage tank 601 is transported to the spraying pipe 604 through the material extraction pump 602 and the material guide pipe 603 to spray the surface of the mold 402. After spraying, the positioning assembly 7 releases the interception, and the electric conveying roller frame 1 continues to work to send the loading platform 401 carrying the sprayed mold out of the chamber 201 and into the next process, such as drying, etc.
