[0002] Metal photo frames are decorative frames commonly used to display photos, paintings or other artworks. Metal photo frames are usually made of metal materials such as aluminum alloy and stainless steel. These materials have the characteristics of light weight, corrosion resistance and good plasticity, so metal photo frames excel in durability and aesthetics. Among them, aluminum alloy is the most commonly used material for making metal photo frames, and is favored for its good cost performance and wide range of application scenarios.

[0003] At present, the folding of metal photo frames is processed by two methods: manual and traditional stamping. The manual folding method has low processing precision and low processing efficiency. At the same time, the traditional folding stamping method can only fold one side at a time, so the metal photo frame needs to be folded multiple times, which has low processing efficiency and requires multiple adjustments to the position of the raw materials, which easily leads to low precision of the finished product.

A positioning block 9 is provided on the upper surface of the convex mold plate 4, and an adjustable fixing groove 10 is provided on the surface of the positioning block 9. A fixing bolt 11 runs through the inside of the adjustable fixing groove 10, and a fixed threaded groove 12 is provided on the surface of the convex mold plate 4 near the fixing bolt 11. A hydraulic telescopic rod 13 is installed inside the upper mold core 2, and the telescopic end of the hydraulic telescopic rod 13 is connected to a pressure plate 14. The side surface of the pressure plate 14 is connected to a guide rod 15, and a guide groove 16 is provided on the side surface of the upper mold core 2 near the guide rod 15.

[0024] Preferably, the shapes of the pressing groove 7 and the pressing strip 8 match each other.

[0025] During specific use, when the upper mold base 1 drives the upper mold core 2 to move downward to the surface of the material to be folded 6, the downward movement of the upper mold core 2 can drive the pressure strip 8 to press the material to be folded 6 into the inside of the pressing groove 7, so that a crease can be formed on the surface of the material to be folded 6, which is convenient for the next step of processing.

[0026] Preferably, the positioning block 9 is slidably connected to the fixing bolt 11 via the adjustable fixing groove 10 .

[0027] During specific use, the fixing bolt 11 can move toward the outside of the fixing thread groove 12 when rotating, and then the position of the positioning block 9 can be adjusted.

[0028] Preferably, the fixing bolt 11 and the fixing thread groove 12 are threadedly connected.

[0029] During specific use, the fixing bolt 11 can move toward the inside of the fixing thread groove 12 when rotating in the reverse direction, so that the position of the positioning block 9 can be fixed.

[0030] Preferably, a telescopic structure is formed between the edge holding plate 14 and the hydraulic telescopic rod 13 .

[0031] During specific use, the extension of the hydraulic telescopic rod 13 can drive the edge holding plate 14 to move laterally, so that the position of the edge holding plate 14 can be adjusted, so that the edge holding plate 14 can adapt to the positioning blocks 9 at different positions.

[0032] Preferably, the guide rod 15 is slidably connected to the upper mold core 2 via the guide groove 16 .

[0033] During specific use, when the edge pressing plate 14 is squeezed, it can drive the guide rod 15 to slide inside the guide groove 16 , so that the movement direction of the edge pressing plate 14 can be limited.

[0034] Working principle: When the metal photo frame is used to process the folding die, the position of the positioning block 9 is first fixed by the threaded connection between the fixing bolt 11 and the fixing thread groove 12, and the spacing between the positioning block 9 and the side surface of the pressure plate 14 on the corresponding side surface is the thickness of the material 6 to be folded. At this time, when the upper die seat 1 drives the upper die core 2 to move downward to the surface of the material 6 to be folded, the upper die core 2 moves downward to drive the pressure strip 8 to press the material 6 to be folded into the inside of the pressure groove 7. At the same time, the pressure plate 14 continues to move downward to squeeze the material 6 to be folded downward, and the surface of the material 6 to be folded can be bent under the action of the positioning block 9, so that the three-sided folding of the material 6 to be folded can be achieved;

[0035] When the folding position of the material 6 to be folded needs to be adjusted, the fixing bolt 11 can be rotated first. When the fixing bolt 11 is rotated, it can move to the outside of the fixed thread groove 12. Then the position of the positioning block 9 can be adjusted. Then the fixing bolt 11 can be rotated in the opposite direction. When the fixing bolt 11 is rotated in the opposite direction, it can move to the inside of the fixed thread groove 12. In this way, the position of the positioning block 9 can be fixed. Then the hydraulic telescopic rod 13 can be controlled to extend. The extension of the hydraulic telescopic rod 13 can drive the pressure plate 14 to move horizontally. The distance between the pressure plate 14 and the corresponding side adjustment positioning block 9 is the thickness of the material 6 to be folded. In this way, the material 6 to be folded can be folded at different positions.

[0036] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
