Technical Field

[0001] The utility model relates to the technical field of foamed plastics, and particularly relates to a forming device for foamed plastic products. Background Art

[0002] A foam box is a box-shaped packaging container made of foamed plastics. Due to the countless tiny air holes inside it, these air holes endow it with excellent properties such as light weight, heat insulation, sound insulation, and shock absorption. Therefore, foam boxes are often used in the transportation of fruits and the packaging of items, and are widely used in the fields of logistics, electronics, medicine, food, etc. as thermal insulation packaging. And a forming device for foamed plastic products is required to make foam boxes.

[0003] However, for the existing forming device for foamed plastic products, when adding raw materials into the mold, it does not preheat the mold, which makes the temperature difference between the mold and the raw materials very easy to be too large. And a too large temperature difference is very easy to cause unevenness in the processed products, thus affecting the accuracy and quality of the products.

[0004] To solve this technical problem, the utility model proposes a forming device for foamed plastic products. Content of the Utility Model

Specific implementation manners

[0023] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0024] As Figures 1-5 shown, a foam plastic product forming device includes a fixed frame 1 and a movable frame 2. A concave mold 3 is arranged inside the fixed frame 1, and a convex mold 4 is slidably connected inside the movable frame 2. When the movable frame 2 is connected to the fixed frame 1, at this time, the convex mold 4 will also be connected to the concave mold 3, and the gap between the two is the shape of the product. A feeding pipe is connected to the upper end of the fixed frame 1, and the feeding pipe is communicated with the concave mold 3. Thus, when the fixed frame 1 is connected to the movable frame 2, at this time, foam raw materials can be added into the gap between the convex mold 4 and the concave mold 3 through the feeding pipe.

[0025] A fixed support frame 17 is connected to the upper end of the fixed frame 1. A second motor 18 is connected to the upper end of the fixed support frame 17. The lower end of the fixed support frame 17 is rotatably connected to a vertical threaded rod 19. The driving end of the second motor 18 is connected to the vertical threaded rod 19. Thus, the second motor 18 can drive the vertical threaded rod 19 to rotate. A movable pipe 20 is threadedly connected to the outer end of the vertical threaded rod 19. A liquid spraying pipe 21 is connected to the lower end of the movable pipe 20. Spraying heads are connected to both sides of the liquid pipe 21. An infusion hose 23 is connected to the upper end of the liquid spraying pipe 21. A pipe connector is connected to the upper end of the infusion hose 23. The infusion hose 23 is connected to the release agent liquid tank. Thus, the liquid spraying pipe 21 can spray the release agent.

[0026] A telescopic rod 22 is connected to the side end of the liquid spraying pipe 21. The upper end of the telescopic rod 22 is connected inside the fixed support frame 17. The telescopic rod 22 is used to restrain the liquid spraying pipe 21 so that it cannot rotate and can only move up and down, thereby being able to restrain the moving pipe 20 so that it cannot rotate. Therefore, when the second motor 18 is started to drive the vertical threaded rod 19 to rotate, at this time, the vertical threaded rod 19 will act on the moving pipe 20, and the moving pipe 20 cannot rotate, so it can move up and down, thereby driving the liquid spraying pipe 21 to move up and down to spray the release agent on the surfaces of the concave mold 3 and the convex mold 4. The fixed support frame 17 is used to support and fix the second motor 18, the vertical threaded rod 19, and the telescopic rod 22.

[0027] A fixed frame 5 is connected to the side end of the moving frame 2. A telescopic cylinder 6 is connected inside the fixed frame 5. The fixed frame 5 is used to support and fix the telescopic cylinder 6. The telescopic cylinder 6 is used to push the convex mold 4. After the raw material enters the gap between the concave mold 3 and the convex mold 4, the telescopic cylinder 6 will push the convex mold 4 to extrude the raw material, thereby completing the shaping of the product. Heating wires 7 are arranged inside the fixed frame 1 and the convex mold 4. When electricity is supplied to the heating wires 7, they will generate heat, thereby being able to heat the fixed frame 1 and the convex mold 4. Water cooling pipes 8 are arranged inside the fixed frame 1 and the convex mold 4. The side end of the fixed frame 1 is connected to a first water cooling tank 12. The water cooling pipes 8 inside the fixed frame 1 are connected to the first water cooling tank 12. In this way, the coolant in the first water cooling tank 12 will circulate between the water cooling pipes 8 inside the fixed frame 1 and the first water cooling tank 12, thereby being able to absorb heat and cool down the fixed frame 1.

[0028] Moving rings 9 are connected to both sides of the moving frame 2. A horizontal threaded rod 10 is threadedly connected inside the moving rings 9. A first motor 11 is connected to the side end of the horizontal threaded rod 10. The side end of the fixed frame 1 is connected to a first support frame 13. The first motor 11 is connected to the side end of the first support frame 13. The horizontal threaded rod 10 is rotatably connected inside the first support frame 13. Starting the first motor 11 will drive the horizontal threaded rod 10 to rotate. The rotation of the horizontal threaded rod 10 acts on the moving rings 9, and the moving frame 2 can be driven to move.

[0029] The side end of the horizontal threaded rod 10 is rotatably connected to a second support frame 14. The side end of the second support frame 14 is connected to a second water cooling tank 15. The side end of the water cooling pipe 8 inside the convex mold 4 is connected to a telescopic water pipe 16. The side end of the telescopic water pipe 16 is connected to the second water cooling tank 15. The telescopic water pipe 16 can enable the water cooling pipe 8 inside the convex mold 4 to still be connected to the second water cooling tank 15 after the moving frame 2 moves, so as to be able to absorb heat and cool it down. The lower ends of the first support frame 13 and the second support frame 14 are both connected with mounting plates, and mounting holes are provided inside the mounting plates. Through the mounting plates, the first support frame 13 and the second support frame 14 can be connected and fixed to the ground to fix the overall position of the device.
