[0034] As a further solution of the present invention, the support group includes a base plate 16 and a limit rod 17, the limit rod 17 is fixedly connected to the first molded part 1, the base plate 16 is located on the right side of the first molded part 1, the limit rod 17 is slidably connected to the base plate 16, a second spring 18 is sleeved on the limit rod 17, a first cylinder 19 is fixedly connected to the base plate 16, the first cylinder 19 is used to push the first molded part 1 to move to the left, and a second cylinder 20 is fixedly connected between the first molded part 1 and the second molded part 2.

[0035] like Figure 1-Figure 9 As shown:

[0036] The substrate 16 provides support, and then fluid is injected into the first molded part 1 and the second molded part 2. During the injection process, the air inside the mold cavity is discharged into the collection shell 4 through the first through hole 3 and the second through hole 6. After the air is discharged, the overflowed fluid will also enter the collection shell 4. After cooling is completed, demoulding and waste recycling can be carried out;

[0037] Demolding and recycling of waste materials:

[0038] Then, the first cylinder 19 is started to push the first molded part 1 and the second molded part 2 to move to the left as a whole. At this time, the limit rod 17 slides along the base plate 16 and compresses the second spring 18. During the movement, the sheet-like waste material cooled inside the collection shell 4 will be blocked by the side wall of the sealing plate 5 and then scraped off, so that the waste material is temporarily stored inside the collection shell 4. After the first molded part 1 and the second molded part 2 are moved to the left side of the collection shell 4 as a whole, the second cylinder 20 can be started to move the second molded part 2 relative to the first molded part 1, and demoulding can be performed;

[0039] When the first molded part 1 and the second molded part 2 move to the left as a whole, the second rack rod 15 will mesh with the gear ring 14 and drive the outer sleeve of the one-way bearing 13 to rotate on the inner sleeve. At this time, the inner sleeve of the one-way bearing 13 will not rotate. When the outer sleeve and the gear ring 14 rotate, the first molded part 1 will move to the left. After demoulding is completed, the first molded part 1 and the second molded part 2 can be reset.

[0040] Resetting process of the first molded part 1 and the second molded part 2:

[0041] First, the second molded part 2 is reset to the first molded part 1 by the second cylinder 20, and then the first molded part 1 is reset by shortening the first cylinder 19. At this time, the limit rod 17 will slide along the base plate 16, and the second spring 18 will gradually reset. When the second rack rod 15 on the first molded part 1 is meshed with the ring gear 14 again, the ring gear 14 will drive the outer sleeve and the inner sleeve of the one-way bearing 13 to rotate at the same time. At this time, the one-way bearing 13 will drive the gear 8 to rotate. When the gear 8 rotates, it will mesh with the first rack rod 9 and push the first rack rod 9 to slide leftward along the support rod 7. At this time, the first spring 12 will be gradually compressed, and the first rack rod 9 will push the push plate 10 to slide leftward along the collection shell 4. At this time, the push plate 10 will synchronously drive the scraper 11 to move leftward, so that the scraper 11 releases the obstruction of the collection shell 4. During the movement of the push plate 10, the solidified fluid inside the collection shell 4 will be pushed, so that the waste can move to the left through the collection shell 4 and then be discharged, and then it can be recycled;

[0042] When the first molded part 1 and the second molded part 2 are reset to the initial position, the second rack rod 15 will move to the right side of the gear ring 14 and disengage from the gear ring 14. At this time, the first rack rod 9, the push plate 10 and the scraper 11 will be driven to reset to the initial position under the action of the first spring 12, and then the fluid can be injected again;

[0043] According to the present invention, the collecting shell 4 is arranged to collect and cool the fluid overflowed during the fluid injection process, and then the cooled waste is scraped off by the scraper 11 during the demolding process. When the mold inside the mold cavity is demolded, the cooled waste inside the collecting shell 4 can be pushed out by the push plate 10 during the resetting of the first molded part 1 and the second molded part 2, thereby completing the recycling of the waste, so that the waste will not be molded on the first molded part 1 and the second molded part 2, reducing the difficulty of cleaning and the resistance when opening the mold.

[0044] As a further solution of the present invention, the sealing plate 5 is slidably connected to the collecting shell 4, the bottom end of the scraper 11 is located inside the second through hole 6, the second through hole 6 is slidably connected to the sealing plate 5, and a backflow-free component is provided on the right side of the sealing plate 5. The backflow-free component is used to drive the sealing plate 5 to move along the collecting shell 4 toward the scraper 11 before the first cylinder 19 pushes the first molded part 1 and the second molded part 2 to move to the left.

[0045] As a further solution of the present invention, the backflow-free component includes a support rod 21 and a driving rod 28. The driving rod 28 is fixedly connected to the telescopic end of the first cylinder 19. The driving rod 28 is at a certain distance from the first molded part 1.

[0047] The sealing group includes a fourth spring 24, which is located directly below the support rod 7, the support rod 7 is slidably connected to the base plate 16 in the vertical direction, and the fourth spring 24 is fixedly connected above the base plate 16;

[0048] An adaptation group is arranged on the left side of the sealing group.

[0049] As a further solution of the present invention, the adaptation group includes a fifth spring 25 and a T-rod 26, the T-rod 26 is fixedly connected to the top of the first molded part 1, the T-rod 26 is slidably connected to the second rack rod 15 in the vertical direction, and the fifth spring 25 is sleeved on the T-rod 26 and fixedly connected between the T-rod 26 and the first molded part 1.

[0050] like Figure 3-Figure 5 , Figure 7-Figure 9 As shown:

[0051] There is a certain distance between the driving rod 28 and the side wall of the first molded part 1, and at this time, the ring gear 14 presses down the second rack rod 15, that is, the fifth spring 25 is compressed;

[0052] When the fluid injection is completed, the first cylinder 19 can be directly started to push the driving rod 28 to move to the left. Before the driving rod 28 contacts the first molded part 1, the driving rod 28 will first push the support rod 21 to move through the third spring 23 and the slider 22. The support rod 21 is inclined, so during the movement, it will push the sealing plate 5 to slide to the left along the collecting shell 4, and the second rack rod 15 will also move along the gear ring 14 and drive the gear ring 14 and the outer sleeve of the one-way bearing 13 to rotate on the inner sleeve. At this time, the second through hole 6 on the sealing plate 5 will gradually slide toward the scraper 11 and then gradually seal the second through hole 6, so that the first through hole 3 is isolated from the second through hole 6, and the fluid will temporarily exist inside the collecting shell 4. When the second through hole 6 is completely sealed, the sealing plate 5 cannot continue to move. At this time, the continued movement of the support rod 21 will pass The support rod 21 applies an upward force to the sealing plate 5, and the sealing plate 5 will lift up the collecting shell 4 and the support rod 7, and the support rod 7 will slide upward along the base plate 16 and stretch the fourth spring 24, and the support rod 7 will rise relative to the first molded part 1 and the second molded part 2, and the collecting shell 4 will rise, and the second rack rod 15 will also be disengaged from the gear ring 14, and the second rack rod 15 will rise under the elastic relaxation of the fifth spring 25, and then the driving rod 28 will continue to move a fixed length and then contact the first molded part 1 and push the first molded part 1 and the second molded part 2 to move to the left as a whole, and the elastic relaxation of the third spring 23 can keep the support rod 7 in an ascending state, and after cooling is completed, the second cylinder 20 extends to drive the second molded part 2 to move, and then demoulding is performed;

[0053] The second through hole 6 is sealed by the movement of the sealing plate 5 and the contact with the scraper 11, and the collecting shell 4 is sealed before the support rod 7 and the collecting shell 4 rise, so that the fluid is cooled inside the collecting shell 4;

[0054] After demoulding is completed, the second molded part 2 is first fitted with the first molded part 1, and then the first cylinder 19 is shortened. Under the action of the second spring 18, the first molded part 1 will gradually reset. During the reset process, the second rack rod 15 will mesh with the gear ring 14 and drive the one-way bearing 13 to rotate, so that the push plate 10 can push the fertilizer out. When the first molded part 1 and the second molded part 2 are reset, the first cylinder 19 has not been completely shortened, but will continue to shorten. At this time, the third spring 23 is no longer compressed, but follows the reset of the driving rod 28 to reset the support rod 7 and the sealing plate 5 to their initial positions respectively. At this time, the collecting shell 4 will drop linearly and the fourth spring 24 will pull down the support rod 7 so that the collecting shell 4 can be close to the first molded part 1 and the second molded part 2, thereby ensuring the sealing.
