[0001] This utility model relates to the field of refrigerator manufacturing technology, specifically to a linear refrigerator door foaming fixture. Background Technology

[0002] In the refrigerator manufacturing process, the foaming process of the refrigerator door is one of the key steps. The purpose of foaming is to form a heat insulation layer inside the refrigerator door to improve the refrigerator's heat preservation performance. During the foaming process of the refrigerator door, clamps are often used to clamp and fix the outer shell and the inner liner to prevent deformation caused by foaming pressure, and to ensure the flatness and sealing of the door.

[0003] However, during the foaming process of traditional refrigerator doors, the clamping force of the fixtures and the foaming pressure often cause the foamed refrigerator door to stick tightly to the positioning mold, making it difficult for personnel to remove. This often takes a lot of time, and improper force during removal can damage the surface of the refrigerator door, affecting the appearance quality of the product. Utility Model Content

[0004] The purpose of this utility model is to provide a linear refrigerator door foaming clamp, which can clamp the outer shell and inner liner during the foaming process, while making it convenient for personnel to remove the refrigerator door after the foaming is completed, thus greatly facilitating the work of personnel.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a linear refrigerator door foaming fixture, comprising a workbench, a positioning mold fixedly installed at the middle of the top of the outer surface of the workbench, a lifting plate movably connected to the middle of the positioning mold, push rods fixedly connected to both ends of the bottom of the lifting plate, a movable frame fixedly connected between the bottoms of the two push rods, U-shaped plates fixedly connected to both ends of the top of the movable frame, adjusting screws movably connected to both ends of the top of the workbench via bearings, a second bevel gear fixedly installed at the bottom of the adjusting screw, a movable plate threadedly connected to the upper end of the adjusting screw, a clamping plate fixedly connected between the two movable plates on their adjacent sides, a drive motor fixedly installed at the lower end of the left side of the outer surface of the workbench, a rotating shaft fixedly installed at the output end of the drive motor, and a first bevel gear fixedly installed at both ends of the rotating shaft, the first bevel gear meshing with the second bevel gear.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] The components of this application, including the workbench 1, support column 2, drive motor 3, positioning mold 4, lifting plate 5, clamping plate 6, reinforcing frame 7, moving plate 8, support frame 9, rotating shaft 10, first bevel gear 11, second bevel gear 12, adjusting screw 13, guide slide rod 14, moving frame 15, push rod 16, guide vertical rod 17, reinforcing rod 18, return spring 19, and U-shaped plate 20, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0022] Example 1:

[0023] Please see Figures 1-4As shown, this utility model provides a linear refrigerator door foaming fixture, including a workbench 1. A positioning mold 4 is fixedly installed at the middle of the top of the outer surface of the workbench 1. A lifting plate 5 is movably connected to the middle of the positioning mold 4. Push rods 16 are fixedly connected to both ends of the bottom of the lifting plate 5. A movable frame 15 is fixedly connected between the bottoms of the two push rods 16. U-shaped plates 20 are fixedly connected to both ends of the top of the movable frame 15. Adjusting screws 13 are movably connected to both ends of the top of the workbench 1 through bearings. A second bevel gear 12 is fixedly installed at the bottom of the adjusting screw 13. A movable plate 8 is threadedly connected to the upper end of the adjusting screw 13. A clamping plate 6 is fixedly connected between the two movable plates 8 on their adjacent sides. A drive motor 3 is fixedly installed at the lower end of the left side of the outer surface of the workbench 1. A rotating shaft 10 is fixedly installed at the output end of the drive motor 3. A first bevel gear 11 is fixedly installed at both ends of the rotating shaft 10. The first bevel gear 11 meshes with the second bevel gear 12.

[0024] In this technical solution, the refrigerator door shell and inner liner, internally filled with foaming material, are placed in the positioning mold 4. Starting the drive motor 3 rotates the rotating shaft 10 and the first bevel gear 11. The rotation of the first bevel gear 11 drives the second bevel gear 12 and the adjusting screw 13 to rotate. The rotation of the two adjusting screws 13 causes the moving plate 8 and the clamping plate 6 to move linearly downwards. This movement of the clamping plate 6 applies pressure and clamps the refrigerator door shell and inner liner placed in the positioning mold 4, ensuring that the foaming material is evenly filled between the refrigerator door shell and inner liner during the foaming process. After foaming is complete, starting the drive motor 3 rotates the rotating shaft 10... The first bevel gear 11 rotates in the opposite direction. The rotation of the first bevel gear 11 drives the second bevel gear 12 and the adjusting screw 13 to rotate, which in turn drives the moving plate 8 and the clamping plate 6 to move upward. This causes the clamping plate 6 to detach from the top of the foamed refrigerator door and, under the continuous movement of the moving plate 8, to contact the U-shaped plate 20 and push the U-shaped plate 20 upward. The movement of the U-shaped plate 20 drives the moving frame 15, the push rod 16 and the lifting plate 5 to move upward. Under the movement of the lifting plate 5, the foamed refrigerator door can be pushed out from the inside of the positioning mold 4, so that personnel can quickly remove the foamed refrigerator door, effectively improving the efficiency of personnel material handling.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figures 1-4As shown, support frames 9 are fixedly connected to both ends of the top of the outer surface of the workbench 1. The top of the adjusting screw 13 is movably connected to the top of the inner cavity of the support frame 9 through a bearing. Guide vertical rods 17 are fixedly connected to the upper ends of both sides of the support frame 9. The top of the U-shaped plate 20 is slidably connected to the surface of the guide vertical rod 17. A reinforcing frame 7 is fixedly connected to the top of the clamping plate 6. Reinforcing rods 18 are fixedly connected to both sides of the clamping plate 6. The surface of the reinforcing rods 18 is fixedly connected to the surface of the moving plate 8. Guide slide rods 14 are fixedly connected to both ends of the top of the inner cavity of the workbench 1. The surface of the moving frame 15 is slidably connected to the surface of the guide slide rods 14. A return spring 19 is fixedly connected between the bottom of the outer surface of the positioning mold 4 and the top of the moving frame 15. There are two return springs 19. Support columns 2 are fixedly connected to all four sides of the bottom of the outer surface of the workbench 1. A support base plate is fixedly connected between the bottom of the two support columns 2. The right side of the rotating shaft 10 is movably connected to the right side of the inner cavity of the workbench 1 through a bearing.

[0027] In this technical solution, the support frame 9 and guide rod 17 are used to support and guide the adjusting screw 13 and U-shaped plate 20, respectively, to prevent the adjusting screw 13 and U-shaped plate 20 from tilting due to force. The reinforcing frame 7 and reinforcing rod 18 are used to strengthen the clamping plate 6 and the space between the clamping plate 6 and the moving plate 8. The guide slide rod 14 is used to guide the moving frame 15, to prevent the moving frame 15 from tilting during movement. The return spring 19 is compressed during the upward movement of the moving frame 15, so that the return spring 19 can generate tension on the moving frame 15. After the moving plate 8 and U-shaped plate 20 are separated, the return spring 19 can push the moving frame 15 downward. The support column 2 and the support base plate are used to support the bottom of the worktable 1.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
