Next, the insertion block 7 can be inserted into the positioning groove 6. Then, the insertion rod 11 and the convex block 13 can be inserted into the fixing hole 8. Next, push the insertion rod 11 upward. Then, the baffle 12 will contact the bottom end of the spring 10 and compress the spring 10. Next, the convex block 13 will pass through the fixing hole 8. Then, the insertion rod 11 can be rotated, and the convex block 13 will rotate accordingly. Next, there will be a dislocation between the convex block 13 and the fixing hole 8, and then the injection head 5 can be fixed.

[0027] Wherein, a base 28 is fixedly installed at the bottom end of the support block 1. An installation plate 14 is fixedly installed at the top end of the base 28. An electric push rod 15 is fixedly installed at the top end of the installation plate 14. The output shaft of the electric push rod 15 penetrates downward through the installation plate 14 and is fixedly installed with a clamping plate 16. A mold 17 is arranged at the top end of the base 28.

[0028] Through the design of the installation plate 14 and the electric push rod 15, the mold 17 can be driven to be placed at the top end of the base 28. Then, the electric push rod 15 can be driven. Next, the output shaft of the electric push rod 15 will push the clamping plate 16 to move, and then the clamping plate 16 will fix the mold 17.

[0029] Wherein, rollers 18 are fixedly installed at the bottom end of the base 28, and the number of the rollers 18 is four.

[0030] Through the design of the rollers 18, the device can be pushed to rotate the rollers 18, and then the rollers 18 will drive the device to move.

[0031] Wherein, an observation window 19 is fixedly installed at the front end of the support block 1, and the observation window 19 is made of a transparent material.

[0032] Through the design of the observation window 19, when the device is working, the operator can view the state inside the collection box 2 through the observation window 19.

[0033] Wherein, a feed pipe 20 is fixedly installed at the top end of the collection box 2, and a plug 21 is movably sleeved on the surface of the feed pipe 20.

[0034] Through the design of the feed pipe 20 and the plug 21, the raw materials for injection molding can be poured into the collection box 2 from the feed pipe 20. After the raw materials are added, the plug 21 can be inserted into the feed pipe 20.

[0035] Wherein, a motor 22 is fixedly installed at the top end of the collection box 2. The output end of the motor 22 extends into the collection box 2 and is fixedly installed with a rotating rod 23. Stirring paddles 24 are fixedly installed on the surface of the rotating rod 23.

[0036] Through the design of the rotating rod 23 and the stirring paddle 24, after the raw materials are added, the motor 22 can be driven to rotate the rotating rod 23. Then, the rotating rod 23 will drive the stirring paddle 24 to rotate. Through the rotation of the stirring paddle 24, the raw materials will be stirred, thereby making the flow of the raw materials smoother.

[0037] Wherein, a rotating ring 25 is fixedly installed on the surface of the rotating rod 23, a connecting rod 26 is fixedly installed on the surface of the rotating ring 25, and a scraping plate 27 is fixedly installed at one end of the connecting rod 26.

[0038] Through the design of the connecting rod 26 and the scraping plate 27, when cleaning the inside of the collection box 2, the motor 22 can be driven again to rotate the rotating rod 23. Then, the rotating ring 25 will rotate accordingly. Then, the rotating ring 25 will drive the connecting rod 26 and the scraping plate 27 to rotate, and then the scraping plate 27 will scrape off the raw materials remaining on the inner wall of the collection box 2.

[0039] The working principle and usage process of the present utility model:

[0040] First, the operator can pour the raw materials into the interior of the collection box 2 through the feed pipe 20. After the raw materials are poured into the interior of the collection box 2, the motor 22 can be driven to rotate the rotating rod 23. Then, the rotating rod 23 will drive the stirring paddle 24 to rotate. Through the rotation of the stirring paddle 24, the raw materials can flow more smoothly. Then, the valve 29 can be opened. Then, the raw materials will flow out through the discharge pipe 3 from the interior of the injection head 5. Then, the raw materials will flow into the interior of the mold 17, thus completing the injection molding. When the injection head 5 needs to be replaced for a long time, the insertion rod 11 can be rotated. Then, the insertion rod 11 will drive the convex block 13. Then, the convex block 13 will be aligned with the fixing hole 8. Then, the compressed spring 10 will push the baffle 12 to move. Then, the baffle 12 will drive the insertion rod 11 and the convex block 13 to move. Then, the convex block 13 will enter the interior of the fixing hole 8. Then, the insertion rod 11 and the convex block 13 can be pulled out from the interior of the fixing hole 8. Then, the insertion block 7 can be removed from the interior of the limiting groove 6. Then, the operator can disassemble the injection head 5 and perform maintenance on it. After the maintenance is completed, the injection head 5 can be placed at the bottom of the flange 4 again. Then, the limiting groove 6 on the surface of the flange 4 and the injection head 5 can be aligned. Then, the insertion block 7 is inserted into the interior of the limiting groove 6. Then, the insertion rod 11 and the convex block 13 can be inserted into the interior of the fixing hole 8 again. Then, the insertion rod 11 is pushed to move. Then, the baffle 12 will compress the spring 10. Then, the convex block 13 will pass through the fixing hole 8. Then, the insertion rod 11 is rotated to cause a dislocation between the convex block 13 and the fixing hole 8. Then, the injection head 5 is fixed. Then, the injection molding can continue. When the interior of the collection box 2 needs to be cleaned after the injection molding is completed, a high-pressure water gun can be used to clean the interior of the collection box 2. During the cleaning process, the motor 22 can be driven again to rotate the rotating rod 23. Then, the rotating rod 23 will drive the rotating ring 25 to rotate. Then, the rotating ring 25 will drive the connecting rod 26 and the scraping plate 27 to rotate. Since the surface of the scraping plate 27 is in contact with the inner wall of the collection box 2, during the rotation of the scraping plate 27, the raw materials remaining on the inner wall of the collection box 2 will be scraped off, thus improving the cleaning effect. Finally, the operation process is completed.
