[0031] See also Figure 3 As shown, the conveying assembly includes a motor 4 installed on the frame 1 by bolt connection, the motor 4 is located on the side close to the feed barrel 2, and a conveying rod 7 for conveying injection molding raw materials is rotatably arranged in the feed tube 6. The conveying rod 7 penetrates to the outside of the feed tube 6, and a bevel gear set 5 for transmission is commonly arranged on the conveying rod 7 and the output shaft of the motor 4.

[0032] See also Figure 4 As shown, the molding assembly includes a first cylinder 8 installed in the injection molding box 101 by means of bolt connection, and a mold plate 9 is installed on the push rod of the first cylinder 8 by means of bolt connection.

[0033] When injection molding is required, the injection molding raw material is poured into the feed barrel 2, and then the motor 4 is started. The transmission of the bevel gear set 5 drives the conveying rod 7 to rotate in the feed pipe 6, so that the conveying rod 7 conveys the injection molding raw material to the injection molding box 101. At this time, the injection molding raw material particles in the feed pipe 6 are melted into liquid through the heating module 701. After the liquid injection molding raw material enters the injection molding box 101, the mold plate 9 is pushed by starting the first cylinder 8 to extrude the liquid injection molding raw material; the injection molding harmful gas generated in the injection molding box 101 is sucked into the filter box 11 by starting the fan 10, and the harmful gas is filtered through the activated carbon net 12 and discharged outside the filter box 11.

[0034] Example 2: Based on Example 1, refer to Figure 6 As shown, it also includes a mounting frame 13 installed on the frame 1 by means of bolt connection, the mounting frame 13 is located at the rear side of the discharge port of the injection molding box 101, and a second cylinder 14 is installed on the mounting frame 13 by means of bolt connection. The push rod of the second cylinder 14 penetrates into the injection molding box 101, and a push plate 15 for pushing the injection molded product is installed on the push rod of the second cylinder 14 by means of bolt connection.

[0035] After the mold plate 9 extrudes the injection molded product, the sliding door 102 is slid open by starting the electric slide rail 3, and then the push plate 15 is pushed out by the second cylinder 14, so that the push plate 15 pushes the injection molded product out of the injection molding box 101.

[0036] See also Figure 7 As shown, it also includes a fixing frame 16 installed on the frame 1 by means of bolt connection, the fixing frame 16 is located at the discharge port of the injection molding box 101, and guide rods 18 are slidably arranged on three sides of the fixing frame 16, and each guide rod 18 is fixedly connected by welding with a scraper 19 for scraping off burrs on the edge of the injection molded product, and a rotating screw 17 is rotatably arranged on the scraper 19, and the rotating screw 17 is threadedly connected to the fixing frame 16, and the scraper 19 is installed at the bottom of the fixing frame 16 by means of welding.

[0037] When the injection molded product is pushed out of the injection molding box 101, the burrs on the edge of the injection molded product are scraped off by the scraper 19 on the fixed frame 16. By rotating the rotating screw 17, the scraper 19 slides on the fixed frame 16 through the guide rod 18 to adjust the spacing of the scraper 19, which is suitable for scraping the edges of injection molded products of different sizes.

[0038] See also Figure 8 and Fig. 9 As shown, it also includes a feeding frame 21 installed on the frame 1 by bolt connection.

A plurality of elastic members 25 are commonly fixedly connected between the feeding frame 21 and the baffle 24 by welding.

[0039] When it is necessary to intermittently lower the injection molding raw material particles, the injection molding raw material particles are poured into the discharge frame 21. When the output shaft of the motor 4 rotates, the connecting rod 22 is driven to rotate on the discharge frame 21 through the transmission of the pulley group 20, so that the cam 23 intermittently pushes the baffle 24 to slide on the discharge frame 21. When the cam 23 pushes the baffle 24 to slide, the discharge frame 21 stops discharging materials. At this time, the elastic member 25 is stretched and deformed by the force. When the cam 23 disengages from the baffle 24, the elastic member 25 pulls the baffle 24 to slide and reset, so that the discharge frame 21 discharges materials into the feed barrel 2.

[0040] See also Figure 2 and Figure 8 As shown, a funnel 26 is installed on the top of the blanking frame 21 by welding, and a protective net 27 is installed at the air outlet of the filter box 11 by bolt connection. The funnel 26 is used to expand the size of the feed opening of the blanking frame 21 to prevent the injection raw material particles from spilling when pouring; the protective net 27 can block the air outlet of the injection molding box 101 to prevent foreign matter from entering the injection molding box 101.
