[0044] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail by means of implementation methods with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0045] It should be noted that: in the accompanying drawings, the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions; in the description of the present application, the terms "center", "longitudinal", "lateral", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; in the description of the present application, "first", "second", etc. are only used to distinguish each other, rather than to indicate their importance and order, etc.

[0046] Before describing the embodiments of the present application, the box in which the foldable side panels are hinged by hinges to achieve folding and storage in the prior art is first introduced. Fig.10 As shown, the side panels 1A and 1B are folded and stored by hinges 1C, but due to the existence of the rotation axis in the hinges 1C, when the side panels 1A and 1B are folded, there must be a gap between the opposite sides of the two panels, and they cannot be stacked completely parallel. Therefore, it is necessary to develop a completely parallel stacking method to further reduce the space occupied by the box when folded and stored.

[0047] The first embodiment of the present application provides a foldable side panel that can be stacked in parallel to reduce the occupied space. Figure 1 , Figure 3 , Figure 4 as well as Figure 5 As shown, the foldable side panel includes a first connecting portion 1 , a second connecting portion 2 , a first side panel 3 and a second side panel 4 .

[0048] The first connection portion 1 is vertically mounted on the first baffle 5, and the second connection portion 2 is vertically mounted on the second baffle 6. Here, the first baffle 5 can be the bottom plate of the box, and correspondingly, the second baffle 6 is the top plate of the box. If the first baffle 5 is the door of the box, correspondingly, the second baffle 6 is the back plate of the box. That is to say, the first baffle 5 is parallel to the second baffle 6, and the first baffle 5, the second baffle 6, the first side plate 3 and the second side plate 4 enclose a placement space for storing items.

[0049] The first connecting portion 1 , the first side plate 3 , the second side plate 4 and the second connecting portion 2 are hingedly connected in sequence through a first connecting member 7 , a second connecting member 8 and a third connecting member 9 , respectively.

[0050] The side of the first side panel 3 facing the placement space and close to the first connecting part 1 is connected to the side of the first connecting part 1 facing the placement space and close to the first side panel 3 through a first connecting member 7. A first clearance groove 10 is provided between the first side panel 3, the first connecting part 1 and the first connecting member 7. The first clearance groove 10 extends along the length direction of the first connecting member 7.

[0051] The side of the second side panel 4 facing away from the placement space and close to the first side panel 3 is connected to the side of the first side panel 3 facing away from the placement space and close to the first side panel 3 through a second connecting member 8, and a second make way groove 11 is provided between the first side panel 3, the second side panel 4 and the second connecting member 8, and the second make way groove 11 extends along the length direction of the second connecting member 8.

[0052] The side of the second side panel 4 facing the placement space and close to the second connecting part 2 is connected to the side of the second connecting part 2 facing the placement space and close to the second side panel 4 through a third connecting member 9, and a third make way groove 12 is provided between the second side panel 4, the second connecting part 2 and the third connecting member 9, and the third make way groove 12 extends along the length direction of the third connecting member 9.

[0053] Preferably, the first connecting member 7, the second connecting member 8 and the third connecting member 9 are all made of flexible materials such as silicone, rubber, etc., and the first connecting member 7, the second connecting member 8 and the third connecting member are all provided with folds extending along the length direction of the first connecting member 7 to facilitate the flipping and folding between the first connecting part 1 and the first side panel 3, the first side panel 3 and the second side panel 4, and the second side panel 4 and the second connecting part 2, so that after the first side panel 3 and the second side panel 4 are flipped and folded, the opposite sides of the two can be parallel and fit together.

[0054] More specifically, when the first baffle plate 5 is the bottom plate of the box body, and the second baffle plate 6 is the top plate of the box body, the front door and the back plate can be detachably installed between the bottom plate, the top plate, the first connecting portion 1, the second connecting portion 2, the first side plate 3, and the second side plate 4. When the first baffle plate 5 is the front door of the box body, and the second baffle plate 6 is the back plate of the box body, the bottom plate and the top plate can be detachably installed between the bottom plate, the top plate, the first connecting portion 1, the second connecting portion 2, the first side plate 3, and the second side plate 4.

[0055] exist Figure 1 In the embodiment, the foldable side panel is in an unfolded state. When in the unfolded state, the first connection portion 1, the second connection portion 2, the first side panel 3 and the second side panel 4 are all in the same plane, and the first connection portion 1 is in contact with the side opposite to the first side panel 3, the first side panel 3 is in contact with the side opposite to the second side panel 4, and the second side panel 4 is in contact with the side opposite to the second connection portion 2. Here, when the first baffle 5 is the bottom plate of the box body and the second baffle 6 is the top plate of the box body, the same plane refers to a vertical plane. When the first baffle 5 is the front door of the box body, the same plane refers to a horizontal plane.

[0056] like Figure 2 As shown, the foldable side panel is in a folded state. When in the folded state, the first side panel 3 and the second side panel 4 are parallel to the first baffle 5, and the first side panel 3 and the second side panel 4 are in contact with each other at opposite sides.

[0057] That is to say, when the foldable side panel changes from the unfolded state to the folded state, the second side panel 4 can be flipped and folded 180 degrees relative to the first side panel 3. When the foldable side panel changes from the folded state to the unfolded state, the second side panel 4 can be flipped and folded 180 degrees relative to the first side panel 3. The first side panel 3 and the second side panel 4 can be folded 0 degrees and unfolded 180 degrees. The 0-degree folding mentioned here means that when the foldable side panel is folded, the opposite sides of the first side panel 3 and the second side panel 4 are completely parallel and overlapped, and the 180-degree unfolding mentioned here means that when the foldable side panel is unfolded, the first connecting portion, the second connecting portion, the first side panel and the second side panel are on the same plane.

[0058] As for the box body, it has two foldable side panels, which are arranged oppositely and parallel to each other. The height of the first baffle 5 is not less than the thickness of the front door or the back panel, and the height of the second baffle 6 is not less than the thickness of the front door or the back panel. In this way, when it is necessary to fold the box body by folding and storing the foldable side panels, the front door and the back panel can be removed first, and then the removed front door and back panel can be placed between the two first connecting parts 1 and / or between the two second connecting parts 2. Preferably, the height of the first baffle 5 is equal to the height of the second baffle 6, the height of the first baffle 5, the thickness of the front door and the thickness of the back panel are the same, and the size of the bottom panel matches the size of the front door and the back panel, so that after the foldable side panels are folded and stored, the front door and the back panel can be placed on the bottom panel, the two first side panels 3, between the two first connecting parts 1, and the top panel, the two second connecting panels and the two second connecting parts 2.

[0059] like Figure 6 As shown, the depth of the second clearance groove 11 is greater than or equal to half of the width of the second connecting member 8, and the second connecting member 8 is provided with three folds arranged along its length direction, two of which are respectively located at the connection between the first connecting member 7 and the first side panel 3 and the second side panel 4, and the other fold is located at the center line of the first connecting member 7 in the width direction, so that after the first side panel 3 and the second side panel 4 are folded toward the inside of the placement space, the second connecting member 8 is folded along another fold, and the folded first connecting member 7 is located in the second clearance groove 11 as a whole. In this way, since the second connecting member 8 is made of flexible material, the folded first side panel 3 and the second side panel 4 can be completely stacked in parallel, and the opposite sides of the two can be attached together, and the folded second connecting member 8 can also be located in the second clearance groove 11, so as to better reduce the space occupied by the foldable side panels and the box body after folding and storage.

[0060] In the foldable side panel, since the first connection part 1, the first side panel 3, the second side panel 4 and the second connection part 2 are hinged in sequence in the first make way groove 10, the second make way groove 11 and the third make way groove 12, the first side panel 3 and the second side panel 4 can be flipped and folded toward the placement space, so that the first side panel 3 and the second side panel 4 can be stacked completely in parallel, thereby reducing the occupied space, and solving the problem in the prior art that the foldable storage side panels are hinged by hinges and the side panels cannot be stacked completely in parallel.

[0061] In addition, when the first baffle plate 5 is the bottom plate of the box and the second baffle plate 6 is the top plate of the box, by removing the front door and the back plate of the box, and after folding the box using the foldable side panels, the front door and the back plate are respectively placed between the bottom plate, the two first side panels 3 and the two first connecting parts 1, and between the top plate, the two second connecting plates and the two second connecting parts 2, which can further facilitate the placement of the front door and the back plate and improve the space utilization efficiency.

[0062] Similarly, when the first baffle 5 is the door of the box and the second baffle 6 is the back panel of the box, by removing the bottom panel and the top panel of the box, after folding the box using the foldable side panels, the bottom panel and the top panel are respectively placed between the front door, the two first side panels 3 and the two first connecting parts 1, and between the back panel, the two second connecting panels and the two second connecting parts 2, which can further facilitate the placement of the bottom panel and the top panel and also improve the space utilization efficiency.

[0063] As a preferred technical solution, the first connecting portion 1 is detachably connected to the first baffle 5, and the second connecting portion 2 is detachably connected to the second baffle 6. In this way, the installation, disassembly, cleaning and replacement of the foldable side panel can be facilitated.

[0064] As a preferred technical solution, when the foldable side panel is in a folded state, the curved portion of the second connecting member 8 located in the second clearance groove 11 is in an arc shape. Compared with providing a fold at the width center line of the second connecting member 8, not providing a fold at the width center line of the second connecting member 8 can avoid the problem of the second connecting member 8 breaking at the fold due to frequent opening and folding of the foldable side panel, and can increase the service life of the second connecting member 8.

[0065] The second embodiment of the present application also provides a mold for producing the above-mentioned foldable side panel. Figure 7 , Figure 8 as well as Fig. 9 As shown, the mold includes a first molding mold 13 and a second molding mold 14, a molding cavity is formed between the first molding mold 13 and the second molding mold 14, the molding cavity matches the foldable side panel, and the second molding mold 14 is provided with a blowing needle 15, an ejection structure 16 and a retracting structure 17.

[0066] The air outlet of the blowing needle 15 is communicated with the molding cavity, and is used to blow air into the molding cavity after the mold is closed, so as to cool the molding mold.

[0067] The ejection structure 16 is used to eject the foldable side panel after the foldable side panel is formed and molded, so as to facilitate the removal of the foldable side panel after forming and cooling.

[0068] The retracted structure 17 is used to retract into the interior of the second molding die 14 after the foldable side panel is molded, so as to facilitate demoulding of the foldable side panel.

[0069] The mold can facilitate the molding, ejection and demolding of the foldable side panel by providing a blow needle 15, an ejection structure 16 and a retracted structure 17, so that the factory can quickly produce the required foldable side panel through the mold. In addition, the foldable side panel produced by the mold can stack the first side panel 3 and the second side panel 4 completely in parallel, reducing the space occupied, solving the problem in the prior art that the foldable storage side panels are hinged by hinges and the side panels cannot be stacked completely in parallel, so it has good practicality.

[0070] As a preferred technical solution, the second molding mold 14 includes a first sub-mold cavity matching the first connecting part 1, a second sub-mold cavity matching the second connecting part 2, a third sub-mold cavity matching the first side panel 3, and a fourth sub-mold cavity matching the second side panel 4. The blow needle 15 passes through the second molding mold 14 and is connected to the molding cavity, and the first sub-mold cavity, the second sub-mold cavity, the third sub-mold cavity and the fourth sub-mold cavity are all provided with the blow needle 15.

[0071] Specifically, after the blow needle 15 passes through the second molding die 14, it is connected with the corresponding first sub-mold cavity, second sub-mold cavity, third sub-mold cavity and fourth sub-mold cavity. In this way, the blow needle 15 can be used to blow air to cool down the first connecting part 1, the second connecting part 2, the first side plate 3 and the second side plate 4 in the molding die cavity.

[0072] As a preferred technical solution, Fig. 9 As shown, the first sub-mold cavity is provided with a first rib 18 protruding toward the molding cavity, and the first rib 18 extends along the length direction of the first connecting member 7, and the second sub-mold cavity is provided with a second rib 19 protruding toward the molding cavity, and the second rib 19 extends along the length direction of the second connecting member 8, and the ejection structure 16 is arranged at both ends of the first rib 18 and the second rib 19.

[0073] Specifically, the ejection structure 16 is an ejector pin, and the ejector pin corresponding to the first rib 18 passes through the first molding die 13 and the first rib 18 and is slidably connected to the first molding die 13 and the first rib 18, and the ejector pin corresponding to the second rib 19 passes through the second molding die 14 and the second rib 19 and is slidably connected to the first molding die 13 and the second rib 19.

[0074] The ejection structures 16 are disposed at both ends of the first rib 18 and the second rib 19 , that is, the ejection structures 16 are disposed at the four corners of the formed foldable side panel, which can facilitate the ejection of the formed foldable side panel.

[0075] Of course, the ejection structure 16 can also be realized by a cylinder and a sliding rod fixedly connected to the piston end of the cylinder. The sliding rod of the ejection structure 16 corresponding to the first sub-mold cavity passes through the second molding die 14 and the first rib 18, and the sliding rod of the ejection structure 16 corresponding to the second sub-mold cavity passes through the second molding die 14 and the second rib 19. When the foldable side panel after molding needs to be ejected, the sliding rod is driven to extend by controlling the action of the cylinder to realize the ejection of the foldable side panel.

[0076] As a preferred technical solution, the third sub-mold cavity and the fourth sub-mold cavity are both provided with the retracted structure 17. Preferably, the retracted structure 17 can be a six-petal retracted structure 17, so that the foldable side panel can be smoothly demoulded after being formed. Since the retracted structure 17 belongs to conventional technical means in the field, it will not be described here.

[0077] The third embodiment of the present application also provides a mold use method, which is applicable to the above-mentioned mold and includes the following steps:

[0078] S1, unloading the blank. Unload the blank through the machine, and then enter step S2.

[0079] S2, closing the molds, using the first molding die 13 and the second molding die to extrude the blank, so as to extrude and form the foldable side panel.

[0080] S3, after the mold is closed, air is blown into the molding cavity through the blow needle 15. This step is mainly used to blow air to cool the product.

[0081] S4, after the foldable side panel is formed, the mold is opened, and the formed foldable side panel is ejected by the ejection structure 16.

[0082] S5, controlling the retracted mold to retract into the interior of the second molding mold 14 to facilitate demoulding of the foldable side panel.

[0083] S6, demoulding. Remove the formed foldable side panel from the mold.

[0084] As a preferred technical solution, in step S3, the blowing time of the blowing needle 15 is 180 seconds.

[0085] The foldable side panels are produced by one-time injection molding to achieve efficient production, thereby improving quality and reducing processing costs.

[0086] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
