[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0033] Reference Figure 1-3A plastic product cooling and molding device, wherein slides 2 are fixedly installed on both sides of the top surface of a workbench 1, and an electric slider 3 is slidably connected in each slide 2. A lower mold 5 and a collection box 10 are fixedly installed on both ends of the top surface of the workbench 1, and an upper mold 7 is installed on the top surface of the lower mold 5. A mounting plate 6 is provided on the upper end of the upper mold 7. A cylinder 8 is fixedly connected to the center of the top surface of the mounting plate 6. The bottom surface of the telescopic end of the cylinder 8 is fixedly connected to the top surface of the upper mold 7. A feed pipe 9 is slidably connected to the top surface of the mounting plate 6 close to the cylinder 8. The lower end of the feed pipe 9 is fixedly connected to the upper mold 7. Two support rods 4 connected to the top surface of the electric slider 3 are fixedly connected on both sides of the bottom surface of the mounting plate 6. A first rack 15 is fixedly connected to the support rod 4 at one end away from the collection box 10. A double gear 17 is meshed and connected on the bar 15, and a cutting assembly is provided inside the upper mold 7 at the connection between the cutting feed pipe 9 and the plastic product on the inner wall of the upper mold 7. One end of the double gear 17 extends to the interior of the upper mold 7 and is connected to the cutting assembly. One end of the double gear 17 is rotatably installed in the upper mold 7 and the other end extends to the outside of the upper mold 7. After the plastic product in the lower mold 5 is cooled, the cylinder 8 is started to lift the upper mold 7. At the same time, one end of the double gear 17 outside the upper mold 7 is meshed with the first rack 15 installed on the support rod 4, and one end of the double gear 17 inside the upper mold 7 will also rotate synchronously. When the upper mold 7 is lifted, it moves in the slide 2 through the electric slider 3, and stops when it moves to the other end of the slide 2. At this time, the lower mold 5 is completely exposed and the plastic product is taken out.

[0034] Reference Figure 3-5 An L-shaped mounting cavity 18 is provided inside the upper mold 7, and the cutting assembly includes a second rack 16 slidably connected in the vertical end of the L-shaped mounting cavity 18, and a cutting plate 14 is slidably connected in the horizontal end of the L-shaped mounting cavity 18. One side of the cutting plate 14 is fixedly connected to the second rack 16. The length of the L-shaped mounting cavity 18 extends to the cylinder 8, and the vertical end of the L-shaped mounting cavity 18 has both the second rack 16 and one end of the double gear 17. When the double gear 17 rotates, it will push the meshing second rack 16 to move, and the cutting plate 14 will move forward at the same time.

[0035] A cutting hole 19 and a guide hole 20 are provided on the top surface of the cutting plate 14. An annular blade 21 with the same inner diameter as the feed pipe 9 is installed inside the cutting hole 19. The guide hole 20 has the same inner diameter as the feed pipe 9. The cutting plate 14 has the cutting hole 19 and the guide hole 20 from one end to the inside. The annular blade 21 installed in the cutting hole 19 will cut the material remaining at the mouth of the feed pipe 9. When the cutting plate 14 moves, the guide hole 20 will be attached to the mouth of the feed pipe 9.

[0036] The end surface of the annular blade 21 is flush with the top surface of the cutting plate 14. The annular blade 21 is flush with the top surface of the cutting plate 14 to ensure the flatness of the cutting surface and will not affect the movement of the cutting plate 14 after cutting.

[0037] Reference Figure 6 The top surface of the mounting plate 6 is provided with a guide rod assembly for clearing the inner wall of the feed pipe 9, and the guide rod assembly includes a connecting rod 11 fixedly connected to the top surface of the mounting plate 6, and the top surface of the connecting rod 11 is rotatably connected to a rotating rod 12, and the rotating rod 12 is slidably connected to a guide rod 13 at one end away from the connecting rod 11. When the mounting plate 6 moves to above the collecting box 10, the lower end of the mouth of the feed pipe 9 is just the collecting box 10, and by lifting the guide rod 13, the rotating rod 12 rotates along the connecting rod 11, and the guide rod 13 is placed into the feed pipe 9 from top to bottom, and the residual and adhered materials inside are ejected, and the ejected materials fall into the collection box 10 below, which is convenient for the next use.

[0038] The length of the guide rod 13 is longer than that of the feed pipe 9. Only when the length of the guide rod 13 is longer than that of the feed pipe 9 can the materials remaining in the feed pipe 9 be completely cleaned.

[0039] Reference Figure 7 A frame-shaped cooling cavity 22 is provided on the inner wall around the lower mold 5, and a water inlet and a water outlet are fixedly connected to one side of the lower mold 5 from top to bottom. When the plastic liquid is injected into the lower mold 5, the plastic liquid inside is cooled from all sides through the frame-shaped cooling cavity 22 on the side wall of the lower mold 5, and then the water in the cooling cavity 22 is circulated and replaced through the water inlet and the water outlet, thereby improving the cooling efficiency.

[0040] Four sets of positioning structures are provided at the center of the sides of the upper mold 7 and the lower mold 5. The positioning structures include a clamping block 23 and a clamping groove 24. The clamping block 23 is arranged at the center of the top surface of the four sides of the lower mold 5. The clamping block 23 is engaged with the clamping groove 24 arranged on the bottom surface of the upper mold 7. When the cylinder 8 pushes the upper mold 7 down to cooperate with the lower mold 5, the clamping block 23 and the clamping groove 24 are provided to provide positioning when the upper and lower molds 5 are closed to prevent displacement.

[0041] Working principle:

[0042] The plastic solution flows into the lower mold 5 through the feed pipe 9, and water is supplied to the cooling chamber 22 through the water inlet and the water outlet to provide cooling for the lower mold 5. After cooling, the cylinder 8 moves upward, and the double gear 17 is meshed with the first rack 15 installed. One end of the double gear 17 in the upper mold 7 pushes the second rack 16 to move, and the cutting plate 14 connected to the second gear also moves synchronously. The annular blade 21 in the cutting hole 19 on the cutting plate 14 cuts the material in the feed pipe 9 when the cutting plate 14 moves. Cutting makes the material in the feed pipe 9 completely separated from the product in the lower mold 5. Due to the movement of the cutting plate 14, the guide hole 20 on the cutting plate 14 will be aligned with the discharge port of the feed pipe 9. When the mounting plate 6 sets the electric slider 3 to move along the slide 2 to the other end, the electric slider 3 stops when it contacts the slide 2. At the same time, the lower mold 5 is completely exposed to take out the cooled product. Then, by placing the guide rod 13 into the feed pipe 9, the material in the feed pipe 9 is ejected and cleaned, and the ejected material falls into the collection box 10 below.

[0043] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and utility model concept of the present application, which should be covered by the protection scope of the present application.
