[0024] Please refer to Figures 1-4 , an embodiment provided by the present invention:

[0025] The lower die 1, die groove 11, upper die 13 and EPE 14 used in this application are products that can be directly purchased on the market, and their principles and connection methods are all prior arts well-known to those skilled in the art, so they will not be elaborated here.

[0026] A cold pressing processing die for an arc-shaped door panel decoration member includes: a lower die 1, a die groove 11 is formed on the top surface of the lower die 1, an upper die 13 is arranged on the upper side of the lower die 1, and an EPE 14 is laid inside the die groove 11;

[0027] A storage groove 12 is formed on the inner wall of the die groove 11;

[0028] An adjusting structure 2 is installed on the lower die 1. The adjusting structure 2 includes a positioning slider 21. The positioning slider 21 is slidably installed inside the storage groove 12. A limiting block 22 is integrally formed on the surface of the positioning slider 21. A screw handwheel 23 is movably installed inside the surface of the positioning slider 21. The positioning slider 21 can telescopically move on the inner wall of the die groove 11, and the angle between both ends of the plate and the cold pressing position can be adjusted. Furthermore, the arc of the plate after cold pressing can be adjusted, which can be applicable to the processing of arc-shaped door panel shapes with various arcs, improving the practicability of the device;

[0029] A positioning structure 3 is installed on the lower mold 1. The positioning structure 3 includes an arc-shaped base 31, and the arc-shaped base 31 is fixedly installed on the front and rear walls of the lower mold 1. The right end of the arc-shaped base 31 is rotatably connected with an arc-shaped pressing plate 32, and a coil spring 33 is fixedly connected to the outer side of the right end of the arc-shaped pressing plate 32. The EPE 14 is laid on the inner side of the mold groove 11, and then the arc-shaped pressing plate 32 is pulled, so that the arc-shaped pressing plate 32 rotates on the arc-shaped base 31, and the arc-shaped pressing plate 32 moves away from the arc-shaped base 31. Then the EPE 14 is laid on the upper side of the arc-shaped base 31, so that both ends of the EPE 14 are located between the arc-shaped base 31 and the arc-shaped pressing plate 32. Then the arc-shaped pressing plate 32 is released, and the arc-shaped pressing plate 32 will reset under the action of the coil spring 33, and the arc-shaped pressing plate 32 will move downward and approach the arc-shaped base 31, and the EPE 14 can be pressed tightly between the arc-shaped base 31 and the arc-shaped pressing plate 32, and the EPE 14 can be fixed on the inner side of the mold groove 11, avoiding the displacement of the EPE 14 during the processing, resulting in indentations on the arc surface during the cold pressing process and affecting the appearance effect.

[0030] Furthermore, the lower mold 1, the mold groove 11 and the upper mold 13 cooperate with each other. The plate on the lower mold 1 can be pressed into the mold groove 11 by the upper mold 13 to press the plate into an arc shape.

[0031] Furthermore, the side wall of the positioning slider 21 is flush with the inner wall of the mold groove 11, and the top surface of the limiting block 22 is attached to the top wall of the storage groove 12. When the positioning slider 21 is received in the storage groove 12, the plate can be attached to the inner wall of the mold groove 11 without affecting the plate. The limiting block 22 can support on the top wall of the storage groove 12, and can prevent the positioning slider 21 from rotating downward in the storage groove 12 during the cold pressing of the plate, causing the displacement or even damage of the positioning slider 21 and affecting the processing effect of the plate.

[0032] Furthermore, the screw handwheel 23 penetrates the lower mold 1 and is threadedly connected to the lower mold 1. Rotating the screw handwheel 23 can drive the movement of the positioning slider 21 in the storage groove 12.

[0033] Furthermore, the top surface of the arc-shaped base 31 is flush with the inner wall of the mold groove 11. Both ends of the EPE 14 are respectively located on two groups of arc-shaped bases 31. The EPE 14 is laid in the mold groove 11 and can be laid straight on the arc-shaped base 31, so that the arc-shaped pressing plate 32 is located outside the lower mold 1, avoiding the arc-shaped pressing plate 32 from affecting the movement of the upper mold 13 in the mold groove 11.

[0034] Furthermore, the bottom surface of the arc-shaped pressing plate 32 is attached to the top surface of the EPE 14. One end of the coil spring 33 is fixedly connected to the arc-shaped base 31. The arc-shaped pressing plate 32 can be pressed on the EPE 14 under the action of the coil spring 33 to fix the EPE 14, avoiding the displacement of the EPE 14 during the processing, resulting in indentations on the arc surface during the cold pressing process and affecting the appearance effect.

[0035] Working principle: Before use, the EPE 14 can be laid on the inner side of the mold groove 11. Then, pull the arc-shaped pressing plate 32, so that the arc-shaped pressing plate 32 rotates on the arc-shaped base 31, and the arc-shaped pressing plate 32 moves away from the arc-shaped base 31. Then, lay the EPE 14 on the upper side of the arc-shaped base 31, so that both ends of the EPE 14 are located between the arc-shaped base 31 and the arc-shaped pressing plate 32. Then, release the arc-shaped pressing plate 32, and the arc-shaped pressing plate 32 will reset under the action of the coil spring 33, and the arc-shaped pressing plate 32 will move downward and close to the arc-shaped base 31, and the EPE 14 can be pressed tightly between the arc-shaped base 31 and the arc-shaped pressing plate 32, which can fix the EPE 14 inside the mold groove 11, avoiding the displacement of the EPE 14 during the processing, resulting in indentations on the arc surface during the cold pressing process and affecting the appearance effect;

[0036] After gluing the stacked plate parts, place them on the top surface of the lower mold 1, and the plate parts can be cold-pressed and shaped by the upper mold 13;

[0037] When processing plate parts with different radian, the screw handwheel 23 can be rotated. The screw handwheel 23 is threadedly connected to the lower mold 1. The rotation of the screw handwheel 23 drives the positioning slider 21 to slide in the receiving groove 12, so that the end of the positioning slider 21 extends out from the inner wall of the mold groove 11. The positioning slider 21 can support both ends of the plate, and then adjust the angle between both ends of the plate and the cold pressing position, so as to be applicable to the processing of arc-shaped door panel shapes with multiple radian, improving the practicability of the device. At the same time, a limiting block 22 is integrally formed on the positioning slider 21, and the limiting block 22 can support on the top wall of the receiving groove 12, which can prevent the positioning slider 21 from rotating downward in the receiving groove 12 during the cold pressing of the plate, causing the displacement or even damage of the positioning slider 21 and affecting the processing effect of the plate.

[0038] The above is only the preferred embodiment of the present invention, and does not impose any form of limitation on the present invention; any ordinary technician in the industry can smoothly implement the present invention according to the instructions of the accompanying drawings and the above description; however, any slight changes, modifications and evolutions made by those skilled in the art within the scope of the technical solution of the present invention by using the above-disclosed technical content are equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
