Description

Technical Field

[0001] This utility model relates to the field of refrigerator door demolding technology, specifically a demolding device for refrigerator door foam molds. Background Technology

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature; it is also a consumer product that keeps food or other items at a constant low temperature. The refrigerator contains a compressor, an ice maker, and a cabinet or box for freezing ice. It is a storage box with a refrigeration unit. The mold used for foam molding is a plastic foam mold. Foaming resin is directly filled into the mold, and when heated, it melts, forming a gas-liquid saturated solution. Through nucleation, numerous tiny bubble nuclei are formed, which grow to create the foam plastic part. Therefore, a demolding device is needed for demolding after molding.

[0003] A rapid demolding device for a refrigerator foaming mold, disclosed in patent publication number CN220741904U, includes a support rod and a demolding platen. The operator pours raw materials into the lower mold and combines the upper and lower molds for foaming production. When demolding is required, a motor is started, driving a threaded rod to rotate. This rotation of the threaded rod moves a movable sleeve, which in turn moves a movable plate that slides on a guide rail. The movement of the movable sleeve then causes a wedge plate to press against a wedge plate, which in turn moves the support rod. This movement of the support rod then moves the demolding platen, thus pushing the mold out of the lower mold for rapid demolding.

[0004] When the above-mentioned device is demolding, it relies on the movement of the moving sleeve to drive the wedge plate one to squeeze the wedge plate two to move. However, since the error between the highest and lowest points of the inclined surface of the wedge plate two is small, it may lead to incomplete demolding, requiring manual demolding by the staff. The demolding efficiency is low. In order to solve the above problems, a demolding device for refrigerator door foam mold is proposed. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A demolding device for a refrigerator door foaming mold includes a lower mold and a guide platform fixedly connected to one side of the lower mold. A movable plate is slidably connected to the top of the guide platform. A guide groove for engaging the movable plate is provided on one side of the lower mold. A drive assembly for driving the movable plate to slide is provided at the bottom of the lower mold.

[0008] The drive assembly includes a toothed plate and a moving groove. The toothed plate is fixedly connected to the bottom of the moving plate. The moving groove is opened at the bottom of the inner wall of the lower mold and extends to the bottom of the inner wall of the guide platform. The toothed plate meshes with a gear. Positioning blocks are fixedly connected to both sides of the lower mold. A fixing block is fixedly connected to one side of a set of positioning blocks.

[0027] Please see Figures 1-4In this embodiment, the demolding device for the foaming mold of the refrigerator door includes a lower mold 11 and a guide platform 12 fixedly connected to one side of the lower mold 11. A movable plate 13 is slidably connected to the top of the guide platform 12. A guide groove 15 for engaging the movable plate 13 is provided on one side of the lower mold 11. A driving component for driving the movable plate 13 to slide is provided at the bottom of the lower mold 11.

[0028] The drive assembly includes a toothed plate 27 and a moving groove 17. The toothed plate 27 is fixedly connected to the bottom of the moving plate 13. The moving groove 17 is formed at the bottom of the inner wall of the lower mold 11 and extends to the bottom of the inner wall of the guide table 12. The toothed plate 27 meshes with a gear 18. The moving groove 17, formed at the bottom of the inner wall of the lower mold 11 and extending to the guide table 12, provides a sliding track for the toothed plate 27, ensuring that the toothed plate 27 moves smoothly along the track when the gear 18 rotates. Positioning blocks 21 are fixedly connected to both sides of the lower mold 11. A fixing block 19 is fixedly connected to one side of a set of positioning blocks 21. A useful device is mounted on the fixing block 19. The motor 20, which drives the gear 18, is started. The gear 18 rotates, and the toothed plate 27 slides in the moving groove 17 through meshing with the gear 18. The toothed plate 27 drives the moving plate 13 to move. The pulley 16 installed at the bottom of the moving plate 13 slides in the sliding groove 14. The moving plate 13 is inserted into the lower mold 11 through the guide groove 15. The motor 20 drives the gear 18 to reverse, so that the moving plate 13 slides from the lower mold 11 to the guide table 12, which makes it convenient for the staff to remove the outer shell of the refrigerator door after completion, avoids incomplete demolding, reduces the number of manual demolding steps, and improves demolding efficiency.

[0029] The lower mold 11 is provided with an upper mold 22 on its top. The positioning block 21 is provided with an adjustment component for driving the upper mold 22 to move up and down. The guide table 12 is provided with a guide component for limiting the sliding of the moving plate 13 on its top.

[0030] The adjustment assembly includes a top plate 25 and an electric hydraulic rod 26. The bottom of the top plate 25 is fixedly connected to the top of the four sets of positioning blocks 21. Two sets of electric hydraulic rods 26 are installed on the top plate 25. The piston rod at the power output end of the electric hydraulic rod 26 is fixedly connected to the top of the upper mold 22. When the electric hydraulic rod 26 is activated, it drives the upper mold 22 to move downward, further limiting the door shell. When the electric hydraulic rod 26 retracts, it causes the upper mold 22 to move upward, facilitating the movement of the moving plate 13 and demolding the refrigerator door shell.

[0031] The guide assembly includes a slide groove 14, which is formed at the bottom of the inner wall of the guide platform 12 and extends to the bottom of the inner wall of the lower mold 11. Several sets of pulleys 16 are slidably connected in the slide groove 14. The pulleys 16 are fixedly connected to the bottom of the moving plate 13. The pulleys 16 installed at the bottom of the moving plate 13 slide in the slide groove 14, which can guide the sliding of the moving plate 13 and reduce the friction at the bottom of the moving plate 13 when it slides.

[0032] The bottom of the upper mold 22 is fixedly connected to a positioning plate 23, and the top of the lower mold 11 is provided with a positioning groove 24 for engaging the positioning plate 23. When the upper mold 22 moves downward, the positioning plate 23 is inserted into the positioning groove 24; when it moves upward, the positioning plate 23 is disengaged from the positioning groove 24, which can limit the refrigerator door shell and facilitate the moving plate 13 to drive the refrigerator door shell into the lower mold 11.

[0033] The bottom of the guide platform 12 is fixedly connected to two sets of fixed columns, which can support the guide platform 12 and make the guide platform 12 more stable.

[0034] A fixed frame is fixedly connected to the top of the movable plate 13. By setting the fixed frame, the refrigerator door shell can be limited, reducing the shaking of the refrigerator door shell during the movement of the movable plate 13.

[0035] The working principle of this utility model is as follows: In use, first, the outer shell of the door is placed on the movable plate 13, then another set of outer shells is secured in the fixed frame. The motor 20 is started, driving the gear 18 to rotate. The toothed plate 27 slides within the movable groove 17 through meshing with the gear 18. The toothed plate 27 drives the movable plate 13 to move. The pulley 16 installed at the bottom of the movable plate 13 slides within the sliding groove 14. The movable plate 13 is then secured into the lower mold 11 via the guide groove 15. Foaming liquid is injected into the outer shell at the top of the movable plate 13. The electric hydraulic rod 26 is activated, driving the upper mold 22 to move downwards, causing the positioning plate 23 to insert into the positioning groove 24, further aligning the outer shell of the door. The upper mold 22 is used to limit the movement of the refrigerator door shell. At the same time, the upper mold 22 moves another set of shells to be clamped on the shell at the top of the moving plate 13. After foaming, the electric hydraulic rod 26 retracts, causing the upper mold 22 to move the positioning plate 23 upward, thereby disengaging it from the positioning groove 24. The motor 20 starts, driving the gear 18 to reverse, causing the toothed plate 27 to slide in the moving groove 17, thereby causing the moving plate 13 to slide outward in the guide groove 15. The moving plate 13 moves the foamed refrigerator door shell to the top of the guide table 12, making it convenient for workers to remove the finished refrigerator door shell, avoiding incomplete demolding, reducing manual demolding steps, and improving demolding efficiency.
