[0024] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0025] In existing technology, a collapsible box includes a base plate, side panels, and a cover, with the cover and base plate respectively located at the upper and lower ends of the side panels. To facilitate handling, a support structure is provided on the lower surface of the base plate to create a gap between the base plate and the ground, allowing forklift forks to reach under the base plate during transport. However, during transportation, when multiple collapsible boxes are stacked together, the support structure can easily slide relative to the cover due to its relatively flat upper surface, posing a safety hazard.

[0026] Therefore, such as Figures 1 to 3 As shown, an embodiment of this utility model provides a mold for manufacturing the cover of a turnover box to solve the above-mentioned technical problems.

[0027] A mold for manufacturing a turnover box lid includes a first template 1 and a second template 2. The first template 1 has a first recess 11, the bottom of which has an elliptical boss 111. The shape of the elliptical boss 111 is the same as the shape of the supporting structure, and the cross-sectional area of ​​the elliptical boss 111 gradually decreases from the first recess 11 towards the direction away from it. The second template 2 has a second recess 21, the shape of which matches the shape of the first recess 11. When the first template 1 and the second template 2 extrude the turnover box lid, a locking groove can be formed at the corresponding position of the elliptical boss 111 on the turnover box lid. When multiple turnover boxes are stacked together, the supporting structure on the bottom plate of one turnover box can be locked into the locking groove of another turnover box, thereby preventing the supporting structure from easily sliding relative to the lid and eliminating potential safety hazards. The cross-sectional area of ​​the elliptical boss 111 gradually decreases from the first recess 11 toward the direction away from the first recess 11, which facilitates the first template 1 to detach from the turnover box cover during the production process.

[0028] To reduce the cost of producing the turnover box lid, the bottom of the first recess 11 is provided with multiple first strip-shaped protrusions 112, and the corresponding positions of the first strip-shaped protrusions 112 form a hollow structure, thereby reducing the amount of material used in the turnover box lid. Some of the first strip-shaped protrusions 112 can be connected to each other to form quadrilaterals, thereby enhancing the overall aesthetics of the turnover box lid. Alternatively, a second strip-shaped protrusion 211 can be provided at the bottom of the second recess 21, so that the corresponding positions of the second strip-shaped protrusion 211 form a hollow structure, thereby reducing the amount of material used in the turnover box lid. To improve the overall aesthetics of the turnover box lid, some of the second strip-shaped protrusions 211 can be connected to each other to form right angles.

[0029] In some embodiments, in order to facilitate accurate alignment between the first template 1 and the second template 2, the first template 1 is provided with a limiting groove 12 and the second template 2 is provided with a limiting block 22. The limiting groove 12 and the limiting block 22 are adapted to each other, and the limiting groove 12 can be engaged with the limiting block 22.

[0030] In some embodiments, the first template 1 is provided with a plurality of first support columns 13, which are spaced apart outside the first recess 11. The second template 2 is provided with a plurality of second support columns 23, which are spaced apart outside the second recess 21. The plurality of first support columns 13 and the plurality of second support columns 23 are adapted to each other. When two adjacent first support columns 13 are pressed together, a hollow structure can be formed between the first template 1 and the second template 2, which can accelerate the heat diffusion from the first recess 11 and the second recess 21 to the outside.

[0031] In some embodiments, in order to accelerate the heat diffusion from the first recess 11 and the second recess 21 to the outside, the first template 1 is provided with a first heat dissipation hole on the surface opposite to the first recess 11, and the second template 2 is provided with a second heat dissipation hole on the surface opposite to the second recess 21.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
