[0024] Example 1:

[0025] Please see Figures 1-4 As shown, this utility model provides an environmentally friendly PET plastic food packaging box molding device, comprising:

[0026] The protective box 2 has a hydraulic cylinder 9 fixedly installed at the upper end of the back side of the protective box 2. The output end of the hydraulic cylinder 9 is fixedly installed with a moving mold 10. A fixed mold 12 is provided in front of the moving mold 10. An electric push rod 21 is fixedly installed at the middle of the front surface of the fixed mold 12. A stripping template 22 is fixedly installed at the output end of the electric push rod 21. The surface of the stripping template 22 is slidably connected to the surface of the fixed mold 12.

[0027] A workbench 1 is fixedly connected to the bottom of the protective box 2. A support platform 5 is fixedly connected between the two ends of the top of the workbench 1. A rubber pad 6 is fixedly installed on the top of the outer surface of the support platform 5. A drive motor 16 is fixedly installed on the left side of the outer surface of the support platform 5. An adjusting screw 18 is fixedly installed at the output end of the drive motor 16. A moving plate 17 is threadedly connected to the left end of the adjusting screw 18. A pusher column 15 is fixedly connected to the top of the moving plate 17.

[0028] In this technical solution, by controlling the extension of the hydraulic cylinder 9, the moving mold 10 can be moved, causing the moving mold 10 to fit tightly against the surface of the fixed mold 12. This facilitates the injection molding of environmentally friendly PET plastic food packaging boxes between the moving mold 10 and the fixed mold 12 using an external injection molding machine. After injection molding is completed, while controlling the retraction of the hydraulic cylinder 9 to move and reset the moving mold 10, the extension of the electric push rod 21 pushes the ejector plate 22 to move. This causes the ejector plate 22 to eject the molded environmentally friendly PET plastic food packaging box from the fixed mold 12. The support platform 5 and the rubber pad 6 can also help to eject the environmentally friendly PET plastic food packaging box from the fixed mold 12. While the box provides support, the rubber pad 6 effectively reduces the chance of damage to the environmentally friendly PET plastic food packaging box due to falling impact. Subsequently, by starting the drive motor 16, the adjusting screw 18 is rotated. The rotation of the adjusting screw 18 causes the moving plate 17 and the pusher column 15 to move to the right. During the movement of the pusher column 15, the environmentally friendly PET plastic food packaging box on the top of the support platform 5 can be pushed to the right, allowing the environmentally friendly PET plastic food packaging box to detach from the inside of the protective box 2. This facilitates personnel to pick up the environmentally friendly PET plastic food packaging box and effectively reduces the risk of personnel being crushed due to misoperation during the material handling process, thus improving the safety of personnel operation.

[0029] It should be noted that, firstly, during the injection molding process, the moving mold 10 is connected to the external injection molding machine and cooling equipment through injection pipes and cooling pipes respectively; secondly, the hydraulic cylinder 9, as existing technology, is connected to the output pipeline of the external hydraulic pump during operation.

[0030] Example 2:

[0031] Based on Embodiment 1, this utility model is as follows: Figures 1-4As shown, guide rods 11 are slidably connected between the four sides of the moving mold 10 and the four sides of the demolding mold 22. The two sides of the guide rods 11 are fixedly installed in the inner cavity of the protective box 2. The surface of the fixed mold 12 is fixedly installed on the surface of the guide rods 11. A transparent observation plate 4 is fixedly installed on the upper right side of the protective box 2. A maintenance door 13 is movably connected to the left side of the protective box 2 via a hinge. A protective side plate 7 is fixedly connected to the top left of the outer surface of the support platform 5. A rubber side pad 8 is fixedly installed on the surface of the protective side plate 7. A rubber sleeve 14 is fitted on the upper end of the pusher column 15. A support plate 20 is fixedly connected to the top right of the inner cavity of the support platform 5. The right side of the adjusting screw 18 is movably connected to the left side of the support plate 20 via a bearing. A guide crossbar 19 is fixedly connected to the middle of the top of the worktable 1. The lower end of the moving plate 17 is slidably connected to the surface of the guide crossbar 19. Support columns 3 are fixedly connected to the four sides of the bottom of the worktable 1. A base plate is fixedly connected between the bottoms of the two support columns 3.

[0032] In this technical solution, the guide rod 11 is used to guide the moving mold 10, the fixed mold 12, and the demolding plate 22, effectively improving the accuracy of the mold closing operation. The transparent observation plate 4 and the maintenance door 13 facilitate personnel to observe the interior of the protective box 2 and perform component maintenance. The protective side plate 7 and the rubber side pad 8 protect the environmentally friendly PET plastic food packaging box from falling off the top of the support platform 5 during demolding. The rubber sleeve 14 effectively reduces the probability of damage caused by collision between the environmentally friendly PET plastic food packaging box and the pusher column 15. The support plate 20 supports the right side of the adjusting screw 18, preventing the adjusting screw 18 from tilting due to force. The guide crossbar 19 guides the moving plate 17, preventing the moving plate 17 from tilting during movement.
