Furthermore, it should be noted that, unless otherwise expressly specified or limited, the term "connected" should be understood in a broad sense. For example, a connection can be a direct connection or an indirect connection through an intermediate medium, and can be a fixed connection, a movable connection, a detachable connection, or an integral connection. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0029] In order to make those skilled in the art better understand the technical solution of the present invention, the following will be combined with the appended drawings in the embodiment of the present invention. Figure 1 -8. Provide a clear and complete description of the technical solutions in the embodiments of the present invention.

[0030] One embodiment of the utility model provides a refrigerator body foaming mold, referring to Figure 1 and Figure 2 , including a fixing base 10, a mold plate 20 detachably connected to the fixing base 10, a first magnetic component 30 connected to the mold plate 20, a second magnetic component 11 connected to the fixing base 10, and the first magnetic component 30 and the second magnetic component 11 are magnetically connected to each other.

[0031] The first magnetic member 30 and the second magnetic member 11 can be magnets with opposite magnetic poles. Alternatively, one of the first magnetic member 30 and the second magnetic member 11 can be a magnet / electromagnet and the other can be a ferromagnetic metal. The first magnetic member 30 and the second magnetic member 11 can be made of one or a combination of iron, cobalt, and nickel. The first magnetic member 30 and the second magnetic member 11 can be detachable or non-detachable components, or can be integrally mounted on another structure.

[0032] The first magnetic component 30 is magnetically connected to the mold plate 20. When the mold plate 20 needs to be replaced, the mold plate 20 can be directly magnetically connected to the fixing seat 10 under the magnetic action of the first magnetic component 30. Therefore, after replacing the required foamed box product during the production process, the staff can directly separate the mold plate 20 and the fixing seat 10, and directly install it during installation without repeatedly disassembling and installing fasteners 27 such as screws and bolts. The operation is convenient and quick.

[0033] Reference Figure 1 and Figure 4 The mold plate 20 has a first side wall 21 facing the fixing base 10 and a second side wall 22 that mates with the side wall of the refrigerator body. The first side wall 21 and the second side wall 22 are located on opposite sides of the mold plate 20. The first side wall 21 of the mold plate 20 is in contact with the fixing base 10. The mold plate 20 has a plurality of weight-reducing grooves 23 formed on one side of the first side wall 21. Reinforcing ribs 24 are provided between adjacent weight-reducing grooves 23. This reduces the weight of the mold plate 20 while ensuring its strength, making it easier and more convenient to disassemble, install, and transfer the mold plate 20.

[0034] Reference Figure 4 and Figure 5 The mold plate 20 is provided with a plurality of mounting grooves 25 on one side of the first side wall 21, and the first magnetic member 30 is located in the mounting grooves 25. In this embodiment, there are four corresponding mounting grooves 25 and four corresponding first magnetic members 30, and the four mounting grooves 25 and the first magnetic members 30 are arranged in a matrix. In an optional embodiment, the mounting grooves 25 and the first magnetic members 30 can also be provided in other numbers, as long as the stability of the connection between the mold plate 20 and the fixing base 10 can be guaranteed.

[0035] The first magnetic part 30 cooperates with the mounting groove 25, and the surface of the first magnetic part 30 is flush with the first side wall 21. When the mold plate 20 is magnetically connected to the fixing seat 10, the first side wall 21 of the mold plate 20 can fit with the fixing seat 10, avoiding the formation of a gap between the mold plate 20 and the fixing seat 10, and preventing the mold plate 20 from tilting or displacing during the production process, so as to ensure the smooth foaming of the refrigerator body.

[0036] Reference Figure 5 The mounting groove 25 has a mounting portion 251 and an extension portion 252 that are interconnected. The shape and size of the mounting portion 251 match the shape and size of the first magnetic component 30. The first magnetic component 30 is engaged with the mounting portion 251, and the cross-sections of the first magnetic component 30 and the mounting portion 251 are both set to be quadrilaterals.

[0037] The extension portion 252 extends outward along the plane of the first side wall 21. Since the first magnetic member 30 is directly magnetically connected to the mold plate 20, when the mold plate 20 needs to be replaced, the gap between the extension portion 252 and the first magnetic member 30 can be used to more easily separate the first magnetic member 30 from the mounting slot 25, thereby facilitating removal of the first magnetic member 30. Four extension portions 252 are provided at the corners of the mounting portion 251. These four removal gaps facilitate the use of clamps or other tools to more conveniently remove the first magnetic member 30.

[0038] Reference Figure 6 Second magnetic members 11 are located on both side walls of the mounting base 10, and are symmetrically arranged about the longitudinal centerline of the mounting base 10. The positions of the first magnetic members 30 and the second magnetic members 11 match, with two first magnetic members 30 corresponding to one second magnetic member 11. This ensures a more uniform magnetic attraction between the mold plate 20 and the mounting base 10, further strengthening the connection between the mold plate 20 and the mounting base 10 and ensuring smooth positioning and foaming of the refrigerator body.

[0039] The second magnetic member 11 has an L-shaped cross section and is connected to the fixing base 10 via bolts or other fasteners. The position of the second magnetic member 11 can be adjusted according to the size and position of the mold plate 20.

[0040] Reference Figure 2 and Figure 3 Two clamping plates 26 are fixedly connected to the mold plate 20. The positions of the two clamping plates 26 correspond to the positions of the two second magnetic elements 11, and the two clamping plates 26 are respectively engaged with the two second magnetic elements 11. The clamping plates 26 have a connecting portion 261 and a bending portion 262 that are connected to each other. The connecting portion 261 and the bending portion 262 are integrally formed into an L shape.

[0041] A card slot is formed between the bending portion 262, the connecting portion 261 and the first side wall 21. The height dimension of the card slot matches the thickness dimension of the second magnetic component 11. When the mold plate 20 and the fixing seat 10 are connected, the card plate 26 can be engaged with the second magnetic component 11. The second magnetic component 11 limits the mold plate 20 through the card plate 26. During the foaming production process, it can prevent the mold plate 20 from being displaced or shaking, so as to ensure more stable limitation of the refrigerator body, thereby ensuring smooth foaming production.

[0042] Reference Figure 6 and Figure 7 In order to facilitate the engagement between the clamping plate 26 and the second magnetic member 11, a receiving groove 111 is provided on the second magnetic member 11 to engage with the connecting portion 261, and an open first guide slope 112 is provided on the open side of the receiving groove 111, that is, an open trumpet-shaped guide surface is provided on the open side of the receiving groove 111, so that the open side of the receiving groove 111 has an engagement space larger than the width of the connecting portion 261, which facilitates the alignment and engagement of the clamping plate 26 and the receiving groove 111 when replacing the mold plate 20.

[0043] A second guiding slope 263 is provided at the corner of the extension portion 252 facing the second magnetic member 11. When the mold plate 20 is connected to the fixing base 10, due to the arrangement of the clamping plate 26 and the second magnetic member 11, it is necessary to first align the clamping plate 26 with the position of the second magnetic member 11 so that the mold plate 20 and the fixing base 10 are in contact with each other, and then push the mold plate 20 to move the clamping plate 26 toward one side of the receiving groove 111. The arrangement of the second guiding slope 263 allows the clamping plate 26 to smoothly engage with the second magnetic member 11, avoiding the possibility of jamming.

[0044] Reference Figure 8 The clamping plate 26 is detachably fixedly connected to the mold plate 20 by fasteners 27 such as screws. A connecting hole 28 is formed on the mold plate 20 through the first and second side surfaces. The end of the connecting hole 28 facing the second side surface is configured in a stepped shape. A threaded hole 264 corresponding to the connecting hole 28 is formed on the connecting portion 261 of the clamping plate 26. The screw passes through the connecting hole 28 from the second side wall 22 of the mold plate 20 to the first side wall 21 and is threadedly connected to the clamping plate 26. The head of the screw fits with the stepped portion of the connecting hole 28, allowing the screw to be completely embedded within the wall thickness of the mold plate 20, thereby preventing the screw or other fasteners 27 from affecting the fit between the mold plate 20 and the refrigerator body.

[0045] In this embodiment, the mold plate 20 may be provided with injection holes corresponding to the foaming holes on the refrigerator body, so as to achieve smooth foaming of the refrigerator body.

[0046] The connection method between the fixing seat 10 and the mold plate 20 in this embodiment can be applied to all foaming equipment, and the above structure is also applicable between multiple fixing seats 10 and mold plates 20 in the same foaming equipment, so it will not be repeated here.

[0047] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
