[0002] There are currently many types of refrigerator covers available on the market. They not only cover the interior space of the refrigerator, but also improve the preservation effect, improve cold air circulation, and prevent odor crosstalk. Choosing the right cover material (such as tempered glass or transparent ABS) and compatible model is very important, as this ensures its sealing and durability. Some products also support user self-installation, which is convenient and quick.

[0003] Referring to patent publication number "CN218342615U", a mold demolding mechanism for processing refrigerator door liners is disclosed, including a mold box body, a placement cavity, and a demolding component. The placement cavity is provided inside the mold box body, and the demolding component is provided below the placement cavity. The demolding component includes a telescopic cylinder, a support column, a top plate, a placement groove, a locking block, and a return spring. The telescopic cylinder is provided at the bottom inside the mold box body, and the support column is provided above the telescopic cylinder.

[0004] As shown in the above technology, when producing refrigerator covers, they are manufactured using molds. After injection molding, demolding is required. Existing demolding mechanisms eject the molded refrigerator covers by pushing them out. However, the existing demolding structure is not closely linked to the mold opening process, which reduces production efficiency and may result in inaccurate demolding positions, making it impossible to completely eject the refrigerator covers. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a refrigerator cover demolding mechanism, which solves the problems of insufficient work and inaccurate demolding position of existing refrigerator cover demolding mechanisms.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a refrigerator cover demolding mechanism includes an upper mold and a lower mold, the lower mold has a cavity for forming the refrigerator cover inside, and a demolding mechanism is provided inside the lower mold, the demolding mechanism includes an ejection component, a pushing component and an adjustable linkage component; The ejection assembly includes a base plate, which is slidably connected to the interior of the lower mold. The bottom of the inner wall of the cavity is provided with multiple grooves, and the top of the inner wall of the lower mold is provided with multiple circular grooves corresponding to the positions of the grooves.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] Please see Figures 1-5 The refrigerator lid demolding mechanism offers two technical solutions: The first embodiment includes an upper mold 1 and a lower mold 2. The lower mold 2 has a cavity 3 for forming a refrigerator cover. The lower mold 2 is provided with a demolding mechanism, which includes an ejection component 5, a pushing component 6 and an adjustable linkage component 7. The ejector assembly 5 includes a base plate 51, which is slidably connected to the interior of the lower mold 2. The bottom of the inner wall of the cavity 3 is provided with multiple grooves 52, and the top of the inner wall of the lower mold 2 is provided with multiple circular grooves 53 corresponding to the positions of the grooves 52. The grooves 52 are slidably connected with top blocks 54. The bottom of the base plate 51 is provided with connecting bolts 55, and the top blocks 54 are threadedly connected to the surfaces of the connecting bolts 55. The circular grooves 53 are provided with springs 56, which are sleeved on the outside of the connecting bolts 55, and the tops of the inner walls of the circular grooves 53 and the tops of the base plate 51 are respectively in contact.

[0018] The pushing component 6 includes two fixed seats 61 on the left and right. A rotating rod 62 is rotatably connected inside each of the two fixed seats 61. An L-shaped rod 63 is fixedly connected to one end of the rotating rod 62. An adjustable linkage component 7 is set at the upper end of the L-shaped rod 63. A protrusion 64 is fixedly connected to the other end of the L-shaped rod 63. A damper 65 is rotatably connected to one side of the fixed seat 61. A roller 66 is fixedly connected to the other end of the rotating rod 62. The telescopic end of the damper 65 is rotatably connected to one end of the roller 66.

[0019] When demolding the refrigerator cover, the demolding mechanism is linked to the mold opening process of the upper mold 1, so that the demolding process of the refrigerator cover is completed at the same time as the mold opening process, which improves the production efficiency of the refrigerator cover. Furthermore, the setting of the damper 65 ensures that the demolding process can be carried out stably, avoiding the occurrence of excessive top force, thus improving the practicality of the device.

[0020] The second embodiment differs from the first embodiment in that the adjustable linkage component 7 includes two front and rear sliding grooves 71 at one end of the L-shaped rod 63. The inner surfaces of the two sliding grooves 71 are slidably connected to sliders 72. Push blocks 73 are fixedly connected to the opposite side of the two sliders 72. An adjusting bolt 74 is rotatably connected to one side of the L-shaped rod 63. A connecting rod 75 is fixedly connected to one side of the push block 73. The connecting rod 75 is threadedly connected to the surface of the adjusting bolt 74.

[0021] During demolding, the demolding process is completed by the cooperation of the rollers 66 on the upper mold 1 and the adjustable linkage component 7. The position of the push plate in the adjustable linkage component 7 is adjusted to adjust the rotation angle of the L-shaped rod 63, thereby adjusting the ejection height to ensure that the refrigerator cover can be ejected accurately.

[0022] During mold opening, the upper mold 1 moves upward and drives the roller 66 to move. The roller 66 moves and contacts the push block 73, which in turn pushes the push block 73 to move. The push block 73 moves and drives the L-shaped rod 63 to rotate. The L-shaped rod 63 rotates and pushes the base plate 51 upward, which in turn causes the circular groove 53 to move. Finally, the cooled and shaped refrigerator cover is ejected. If the circular groove 53 is not flat with the inner surface of the cavity 3 after resetting, the connecting bolt 55 can be rotated for adjustment. The rotation of the connecting bolt 55 causes the circular groove 53 to move upward. In addition, if the ejection is not in place, the adjusting bolt 74 is rotated to move the push block 73. The movement of the push block 73 causes the push block 73 to contact the roller 66 earlier, thereby changing the rotation angle range of the L-shaped rod 63 to adjust the ejection amplitude.
