[0027] Please refer specifically to the attached Figures 1 to 4 , a pressing die for a painted arc-shaped wall panel, comprising an upper die 1 and a lower die 2. The upper die 1 and the lower die 2 cooperate to press the arc-shaped member. The upper die 1 and the lower die 2 are both provided with limiting parts, and the limiting parts position the arc-shaped member.

[0028] In this utility model, the limiting parts are a die groove 11 and a plurality of deep grooves 21. The die groove 11 is arranged at the middle position of the upper die 1, and the plurality of deep grooves 21 are evenly arranged on the lower die 2. The die groove 11 and the deep grooves 21 position the arc-shaped member.

[0029] In this utility model, the arc-shaped member includes a long plate 3, a short plate 4 and a connecting strip 5. The long plate 3 and the short plate 4 are perpendicular to each other, and the connecting strip 5 is arranged at the included angle formed by the connection of the long plate 3 and the short plate 4. The outer side of the connection part of the long plate 3 and the short plate 4 contacts the die groove 11, the other ends of the long plate 3 and the short plate 4 respectively contact the deep grooves 21 on both sides, and the connecting strip 5 is connected to the middle deep groove 21;

[0030] In this utility model, the side walls of the die groove 11 and the deep grooves 21 are both 45° slopes, and the slopes contact and fit with the side walls of the long plate 3, the short plate 4 and the connecting strip 5. The depth of the deep grooves 21 at both ends is greater than the depth of the middle deep groove 21. The cross section of the connecting strip 5 is square, and the widths of the long plate 3 and the short plate 4 are the same as the width of the connecting strip 5. The top of the die groove 11 is provided with a first slot 12, and the first slot 12 cooperates with the sharp angle corresponding to the long plate 3. The deep groove 21 is provided with a second slot 23, and the second slot 23 respectively cooperates with the sharp angles corresponding to the long plate 3, the short plate 4 and the connecting strip 5.

[0031] In the present utility model, glue overflow grooves 13 are symmetrically formed on the slopes of the die grooves 11, and the glue overflow grooves 13 correspond to the connection positions of the long plate 3 and the short plate 4; the corresponding positions where the long plate 3, the short plate 4 and the connecting strip 5 contact form a glue overflow platform 22 with the end face of the lower die 2.

[0032] The principle of a paint arc wall panel pressing die of the present utility model is as follows:

[0033] During use, the lower sharp corners of the short plate 4, the connecting strip 5 and the long plate 3 are sequentially placed into the deep groove 21, and then the upper die 1 moves downward to contact the other sides of the short plate 4 and the long plate 3 to press the arc rough blank. During the pressing process, the glue at the connection will overflow into the corresponding glue overflow grooves 13 and the glue overflow platform 22.

[0034] The upper and lower dies 2 are pressed once to form:

[0035] Advantages of the upper die 1:

[0036] 1. The die is made of a density board with a length of 2740 mm and a thickness of 40 mm + 16 mm by pressing.

[0037] 2. After pressing, the die is perfectly formed by using a cnc 45° cutter 4 times to ensure that the length of the die is a straight line at 45° as a whole, and the two slopes meet the pressing accuracy requirements.

[0038] 3. When the two slopes of the die are milled at cnc 45°, they are overlapped twice to form a slope surface, and the length of the slope surface is controlled to be 50 mm in order to achieve the later pressing and the coincidence degree of surface to surface.

[0039] 4. The advantage of the 6*6 slot in the middle of the die is to solve the problem that when pressing, the 45° sharp corners of the components directly touch the die, damaging the right angles of the components. Instead, the sharp corners are suspended, and the two planes contact the die to ensure the aesthetics and qualification rate of the components after pressing.

[0040] 5. The highlight of the 5*5 slots on both sides is to solve the problem that when pressing, the glue overflows and damages the die, ensuring the service life of the die. The reasonable treatment method of the glue increases the firmness of the product and improves the working efficiency during processing.

[0041] Advantages of the lower die 2:

[0042] 1. The die is made of a density board with a length of 2740 mm, a thickness of 40 mm and a width of 600 mm. After the die is finished, the width is 165 mm and it is processed by cnc once.

[0043] 2. The three 45° depths and the interval widths in the die are obtained through repeated tests to ensure that the three components are evenly stressed during subsequent pressing, ensuring the firmness of the glue pressing in place and ensuring the vertical 90° quality qualification rate of the components.

[0044] 3. The perfect design of two 6-mm planes in the mold solves the problem of glue overflow during pressing, increases the service life of the mold, and improves the production efficiency of the product.

[0045] 4. The advantage of the three 5*4 grooves in the mold is that when pressing, it avoids the 45° sharp corners of the component directly touching the mold and damaging the right angles of the component. Instead, the sharp corners are suspended, and two planes contact the mold to ensure the aesthetics and qualification rate of the component after pressing.

[0046] The above exemplary description of the present invention is made in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as this non-substantial improvement is made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
