[0034] Refer to Figure 1, which shows a schematic diagram of the structure of a mold device for box foaming in an embodiment of the present application. The mold device for box foaming provided in an embodiment of the present application includes an outer mold 100 and an inner mold 200. The outer mold 100 includes a first side panel assembly 110 that is enclosed. The inner mold 200 includes a second side panel assembly 210 that is enclosed, and the inner mold 200 is used to be embedded in the outer mold 100, so that a foaming cavity is formed between the first side panel assembly 110 and the second side panel assembly 210, and the foaming cavity is used to install the box 10. Among them, a first flow channel 111 is provided on the side of the first side panel assembly 110 facing away from the foaming cavity, and a second flow channel 211 is provided on the side of the second side panel assembly 210 facing away from the foaming cavity, and the first flow channel 111 and the second flow channel 211 are used to pass a fluid of a preset temperature.

[0035] In the above-mentioned mold device for box foaming, the inner mold 200 is embedded in the outer mold 100, so that a foaming cavity is formed between the first side panel assembly 110 and the second side panel assembly 210, so that the box 10 can be installed in the foaming cavity and can be sandwiched between the inner mold 200 and the outer mold 100 for foaming treatment. The structure is simple and reliable, which helps to improve work efficiency. In addition, a first flow channel 111 is provided on the side of the first side panel assembly 110 away from the foaming cavity, and a second flow channel 211 is provided on the side of the second side panel assembly 210 away from the foaming cavity. In this way, a fluid with a preset temperature can be passed into the first flow channel 111 and the second flow channel 211, thereby controlling the temperature of the inner mold 200 and the outer mold 100, and then realizing the temperature control of the foaming cavity. In this way, after the foaming liquid is poured, the fluidity and distribution uniformity of the foaming liquid at the preset temperature can be improved, thereby improving the effect of the foaming treatment.

[0036] Specifically, as shown in FIG. 2 , the second side panel assembly 210 may be composed of four side panels of equal height. The first side panel assembly 110 may be composed of four side panels, two of which are adjacent to each other and are relatively high, and the other two are adjacent to each other and are relatively low, so as to adapt to the shape of the box 10. In some other embodiments, when the box 10 is of equal height, the first side panel assembly 110 and the second side panel assembly 210 can be designed as equal height structures. Therefore, the heights of the first side panel assembly 110 and the second side panel assembly 210 can be specifically designed according to the shape of the box, so as to improve the applicability of the mold device for box foaming, which will not be described in detail here.

[0037] Optionally, the fluid of the preset temperature may be water, an aqueous solution or an oily liquid, etc., and a specific fluid may be selected according to actual temperature requirements, so as to improve the accuracy of fluid temperature control. Preferably, the fluid is water.

[0038] As shown in combination with Figures 1 and 2, in some embodiments, the second side panel assembly 210 is provided with at least two lifting rings 212 spaced apart along the edge of the panel. The lifting rings 212 are used to lift the inner mold 200 into the outer mold 100, or lift it away from the outer mold 100, thereby enabling the installation and demolding of the inner mold 200, and the structure is simple and reliable.

[0039] For ease of understanding, the hoisting process of the inner mold 200 is explained below. First, before the inner mold 200 is embedded in the outer mold 100, the box body 10 to be foamed needs to be embedded in the outer mold 100. Then, the inner mold 200 is hoisted into the box body 10 from the upper opening position of the box body 10, so that the box body 10 is clamped between the inner mold 200 and the outer mold 100. The clamping space between the outer mold 100 and the inner mold 200 is a foaming cavity, and the foaming night is poured into the foaming cavity to achieve the foaming treatment of the box body 10. It is understandable that when the inner mold 200 is loaded into the box body 10, it can also be installed manually, which will not be repeated here. Furthermore, after completing the foaming treatment of the box body 10, the inner mold 200 can be lifted from the outer mold 100 by the lifting ring 212 to achieve demolding. In this embodiment, by providing the hanging ring 212, on the one hand, the convenience of installing the inner mold 200 can be improved, and on the other hand, the demoulding efficiency of the inner mold 200 can be improved, and the structure is simple and reliable.

[0040] Continuing with Figures 2 to 5, Figure 3 is a schematic diagram of the assembly of the inner mold 200 and the first bottom plate 120 in the box foaming mold device shown in Figure 1. Figure 4 is a schematic diagram of the structure of the assembly structure shown in Figure 3 without the second side plate assembly 210. Figure 5 is an exploded view of the structure shown in Figure 4.

[0041] The outer mold 100 further includes a first bottom plate 120, which is connected to the first side plate assembly 110, so that the outer mold 100 forms a container with an opening on one side. The inner mold 200 further includes a second bottom plate 220, which is connected to the second side plate assembly 210. The first bottom plate 120 is provided with a positioning groove 121. The second bottom plate 220 is provided with a positioning block 221. When the inner mold 200 is embedded in the outer mold 100, the positioning block 221 is clamped in the positioning groove 121, so that the assembly stability and assembly efficiency of the inner mold 200 can be improved.

[0042] In some embodiments, the inner mold 200 further includes at least two demolding mechanisms 230, and the demolding mechanisms 230 are disposed on the second bottom plate 220. The demolding mechanism 230 includes a driving mechanism 231 and a telescopic rod (not shown). The driving mechanism 231 is used to drive the telescopic rod to pass through the second bottom plate 220 to perform telescopic movement, so that the telescopic rod can abut and push the first bottom plate 120, and the inner mold 200 can be separated in a direction away from the first bottom plate 120, so that the inner mold 200 can be automatically demolded, which helps to improve work efficiency.

[0043] Specifically, when the inner mold 200 is not demoulding, the telescopic rod is in a retracted state, the telescopic rod does not contact the first bottom plate 120, and the inner mold 200 is fixed by the positioning block 221 on the second bottom plate 220. When the inner mold 200 needs to be demoulded, the driving mechanism 231 drives the telescopic rod to pass through the second bottom plate 220, and makes the telescopic rod abut and push the first bottom plate 120, so that the driving mechanism 231 is lifted away from the first bottom plate 120 under the reaction force of the telescopic rod. Since the driving mechanism 231 is fixed on the second bottom plate 220 of the inner mold 200, the driving mechanism 231 can drive the inner mold 200 to separate from the outer mold 100, so that the inner mold 200 is automatically demoulded. Preferably, the demoulding mechanism 230 can be set to four, symmetrically distributed at the four corners of the second bottom plate 220, so that the force balance of the inner mold 200 during demoulding can be improved, thereby improving the demoulding effect.

[0044] As shown in combination with FIG. 1 and FIG. 2 , in some embodiments, the inner mold 200 is further provided with a foaming baffle 240, which is disposed protrudingly along one side edge of the second side panel assembly 210 around the axis of the second side panel assembly 210. When the inner mold 200 is embedded in the outer mold 100, the foaming baffle 240 is used to abut against the inner wall of the first side panel assembly 110 to seal the foaming cavity, thereby improving the heat preservation effect of the foaming cavity and further improving the foaming effect.

[0045] Specifically, the foam baffle 240 is detachably connected to the second side panel assembly 210, so that the foam baffle 240 can be installed only after the inner mold 200 is embedded in the outer mold 100. This can avoid the problem of structural interference between the foam baffle 240 and the box body 10 during the embedding process of the inner mold 200, thereby helping to protect the structure of the box body 10.

[0046] 1 and 2 , in some embodiments, the first side panel assembly 110 is connected to a first limiting plate 130 . When the inner mold 200 is embedded in the outer mold 100 , the first limiting plate 130 is used to support the box body 10 , thereby improving the assembly stability of the box body 10 .

[0047] Specifically, as shown in FIG. 1 , when the box 10 is installed in the outer mold 100, the first limiting plate 130 is used to abut against the upper edge of the box 10, so that the box 10 remains stable under the clamping force of the first limiting plate 130 and the first bottom plate 120, thereby helping to reduce the vibration or movement of the box 10 and improve the effect of the foaming treatment. In addition, through the provision of the first limiting plate 130, when the inner mold 200 is demoulded, the box 10 can remain fixed under the limiting effect of the first limiting plate 130, and then the inner mold 200 can move relative to the box 10 to achieve demoulding, which helps to improve the demoulding effect.

[0048] Furthermore, in some embodiments, the first side plate assembly 110 is connected to a second limiting plate 140, and the second limiting plate 140 is connected to the side of the first side plate assembly 110 opposite to the first limiting plate 130. When the box 10 is embedded in the first side plate assembly 110, the second limiting plate 140 is used to support the side of the box 10 opposite to the first limiting plate 130, which can further improve the assembly stability of the box 10. Specifically, by setting the second limiting plate 140, the box 10 can be stressed on both sides, thereby avoiding the situation where the box 10 is unevenly stressed, which helps to improve the fixing effect of the box 10.

[0049] In some embodiments, the mold device for box foaming includes a diverter block (not shown), which is used to be connected to the first flow channel 111 and the second flow channel 211. The diverter block is used to connect to the temperature control pipe, and the temperature control pipe is used to pass the fluid of a preset temperature, and then the fluid is passed into the first flow channel 111 and the second flow channel 211 through the diverting effect of the diverter block, thereby realizing the temperature control of the foaming cavity.

[0050] As shown in FIG. 1 , in some embodiments, the first side panel assembly 110 includes a first side door 112, a second side door 113, and a door lock mechanism 114. The first side door 112 and the second side door 113 can be closed or opened in a direction of being relatively close to each other or away from each other. The door lock mechanism 114 is used to lock the first side door 112 and the second side door 113 when they are closed. The above arrangement can realize the function of installing the box 10 in the form of a horizontally opening door by the mold device for box foaming, which helps to improve the ease of assembly of the box 10 and improve work efficiency.

[0051] 2, in some embodiments, the first flow channel 111 and the second flow channel 211 are both provided with a temperature measuring hole 115. The temperature measuring hole 115 is used to monitor the fluid temperature in the first flow channel 111 and the second flow channel 211, so that the fluid temperature can be adjusted in time to improve the foaming effect.

[0052] In some embodiments, the first side panel assembly 110 is in the shape of a cuboid, the second side panel assembly 210 is in the shape of a quadrangular pyramid, the second side panel assembly 210 includes a first end and a second end, the cross-sectional area of ​​the first end is larger than the cross-sectional area of ​​the second end, and the inner mold 200 can be embedded in the outer mold 100 in the direction from the first end to the second end, thereby reducing the risk of structural interference when the inner mold 200 is embedded and improving the installation convenience of the inner mold 200. Similarly, when performing the demolding operation of the inner mold 200, the quadrangular pyramid-shaped setting of the second side panel assembly 210 also helps to improve the safety of demolding.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
