It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0018] Please refer to Figures 1-3, the present utility model provides a technical solution: a foaming mold for the inner lining of a refrigerator door panel, including an upper mold 1 and a lower mold 2. The upper mold 1 is rotatably connected to the lower mold 2. A plurality of grooves 15 are formed on both side walls of the upper mold 1. A positioning post 4 is arranged in each groove 15. Accommodating grooves 16 adapted to each groove 15 are formed on both side walls of the lower mold 2. A rotating shaft 6 is rotatably arranged in the accommodating groove 16. A gear 5 is fixedly connected to the surface of the rotating shaft 6. A positioning hook 3 that can be snapped into the positioning post 4 is fixedly connected to the surface of the rotating shaft 6. A first rack plate 7 meshing with the gear 5 is slidably arranged at the bottom of the inner wall of the accommodating groove 16. A second rack plate 8 meshing with the first rack plate 7 is slidably arranged in the accommodating groove 16. A placement groove 17 is formed at the front side of the accommodating groove 16. A driving component for driving the second rack plate 8 to slide is arranged in the placement groove 17.

[0019] In this embodiment, the positioning post 4 of the upper mold 1 is used to cooperate with the positioning hook 3 of the lower mold 2. The positioning hook 3 is fixedly connected to the rotating shaft 6 and can rotate with the rotating shaft 6 and be snapped into or disengaged from the positioning post 4. After the positioning hook 3 is snapped into the positioning post 4, the upper mold 1 and the lower mold 2 will not separate.

[0020] When the upper mold 1 and the lower mold 2 are separated, the positioning hook 3 is in a non-engaged state.

[0021] Start the driving component to drive the second rack plate 8 to slide. The second rack plate 8 drives the first rack plate 7 to move, thereby driving the gear 5 to rotate. The rotation of the gear 5 drives the rotating shaft 6 and the positioning hook 3 to rotate, so that the positioning hook 3 is snapped into the positioning post 4 of the upper mold 1, realizing the positioning connection between the upper mold 1 and the lower mold 2.

[0022] Operate the driving component in the reverse direction, so that the second rack plate 8 slides in the reverse direction. The first rack plate 7 moves accordingly, driving the gear 5 to rotate in the reverse direction. The rotating shaft 6 and the positioning hook 3 rotate in the reverse direction, and the positioning hook 3 disengages from the positioning post 4, and the upper mold 1 and the lower mold 2 are separated.

[0023] Furthermore, a first connecting plate 9 is fixedly connected to the front ends of the two first rack plates 7, and a second connecting plate 10 is fixedly connected to the front ends of the two second rack plates 8.

[0024] In this embodiment, the first connecting plate 9 and the second connecting plate 10 can ensure that the first rack plate 7 and the second rack plate 8 can move smoothly and accurately, improving the stability during the movement process.

Since the lead screw 11 is threadedly connected to the threaded sleeve 12 on its surface, the threaded sleeve 12 is driven to move. The connecting rod 13 is fixed to the surface of the threaded sleeve 12, thereby driving the connecting rod 13 to move forward, and then driving the second connecting plate 10 to move. Since the second connecting plate 10 is fixedly connected to the two second rack plates 8, the second rack plates 8 are driven to move forward. Since the second rack plates 8 are engaged with the first rack plate 7, the first rack plate 7 is driven to move forward. Since the first rack plate 7 is engaged with the gear 5, the gear 5 is driven to rotate. Since the gear 5 rotates, the rotating shaft 6 is driven to rotate, and then the positioning hook 3 is driven to rotate and engage with the positioning post 4 to fix the upper mold 1 and the lower mold 2.

[0027] Furthermore, cooling channels are provided in the inner cavities of both the upper mold 1 and the lower mold 2.

[0028] In this embodiment, the cooling channels can quickly conduct the heat accumulated inside the mold, reduce the mold temperature, and thus accelerate the cooling and solidification speed of the product.

[0029] The working principle and usage process of the present utility model: After the present utility model is installed, turning the crank handle drives the handle 14 to rotate, thereby driving the lead screw 11 to rotate. Since the lead screw 11 is threadedly connected to the threaded sleeve 12 on its surface, the threaded sleeve 12 is driven to move. The connecting rod 13 is fixed to the surface of the threaded sleeve 12, thereby driving the connecting rod 13 to move forward, and then driving the second connecting plate 10 to move. Since the second connecting plate 10 is fixedly connected to the two second rack plates 8, the second rack plates 8 are driven to move forward. Since the second rack plates 8 are engaged with the first rack plate 7, the first rack plate 7 is driven to move forward. Since the first rack plate 7 is engaged with the gear 5, the gear 5 is driven to rotate. Since the gear 5 rotates, the rotating shaft 6 is driven to rotate, and then the positioning hook 3 is driven to rotate and engage with the positioning post 4 to fix the upper mold 1 and the lower mold 2.

[0030] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
