[0028] Embodiment 1

[0029] See also Figure 1 and Figure 2 , a shaping mechanism for a mobile phone metal frame. When producing a mobile phone metal frame, it is necessary to first bend the metal strip to form two U-shaped frame pieces, and then connect the two U-shaped frame pieces together to form the mobile phone metal frame. This application actually shapes the right angle of the bending of the frame piece 3. The shaping mechanism of the mobile phone metal frame includes a lower mold 2, which includes an inner slider seat 21. Both sides of the inner slider seat 21 are provided with inclined inner slideways 211. Inner sliders 22 are slidably arranged on the inner slideways 211, so that the inner sliders 22 can slide along the inclined inner slideways 211. The lower mold 2 also includes two outer slider seats 23. The two outer slider seats 23 are respectively located on the side of the two inner sliders 22 away from the inner slider seats 21. The side of the outer slider seat 23 close to the inner slider 22 is provided with an inclined outer slideway 231. An outer slider 24 is slidably arranged on the outer slideway 231. Since the number of the outer slider seats 23 is two, the number of the outer sliders 24 is also two. A space for placing the vertical edge 31 of the frame member 3 is formed between the inner slider 22 and the outer slider 24 located on the same side.

[0030] like Figure 1 When the inner slider 22 and the outer slider 24 both slide upward, the inner slider 22 and the outer slider 24 on the same side move away from each other, so that the horizontal distance between the inner slider 22 and the outer slider 24 on the same side is greater than the thickness of the vertical edge 31, so that the vertical edge 31 of the frame member 3 can enter the space between the inner slider 22 and the outer slider 24. At this time, the two inner sliders 22 are close to each other, and the distance between the farthest ends of the top surfaces of the two inner sliders 22 is less than the length of the horizontal edge 32 of the frame member 3, so that the horizontal edge 32 of the frame member 3 is conveniently placed on the top surfaces of the two inner sliders 22, so that the entire frame member 3 can be conveniently placed in the lower mold 2;

[0031] like Figure 2 When the inner slider 22 and the outer slider 24 both slide downward, the inner slider 22 and the outer slider 24 on the same side approach each other, so that the outer slider 24 squeezes the outer edge of the vertical edge 31 from the outside to the inside, and at the same time, the inner slider 22 squeezes the inner edge of the vertical edge 31 from the inside to the outside. Under the simultaneous squeezing action of the inner slider 22 and the outer slider 24, the vertical edge 31 of the frame member 3 can be corrected, so that the bending angle between the vertical edge 31 and the horizontal edge 32 meets the verticality requirement. When in use, the operator first puts the frame member 3 into the lower mold 2, and then presses the outer slider 24 downward. The outer slider 24 can be pressed downward by a press or other downward pressing structure, so that the outer slider 24 slides downward while driving the frame member 3 to move downward and the inner slider 22 to slide downward, thereby realizing the shaping of the metal frame of the mobile phone. Compared with manual shaping, it saves more manpower, has a better shaping effect, and can improve the shaping efficiency, thereby meeting the shipment requirements.

[0032] When the outer slider 24 slides downward and contacts the frame member 3, the outer slider 24 squeezes the outer edge of the vertical side 31 from the outside to the inside. The outer slider 24 continues to slide downward to drive the frame member 3 to move downward. When the frame member 3 moves downward, the inner slider 22 is pressed by the frame member 3 and also slides downward, so that the inner slider 22 squeezes the inner edge of the vertical side 31 from the inside to the outside.

[0033] Specifically, the lower mold 2 includes a lower pad 25, and the inner slider seat 21 and the outer slider seat 23 are both installed on the lower pad 25. The lower pad 25 is used to install the inner slider seat 21 and the outer slider seat 23. The inner slider seat 21 and the outer slider seat 23 can be installed on the lower pad 25 by screw fixing, snap fixing or adhesive fixing.

[0034] Preferably, the lower mold 2 includes a lower base plate 26 disposed at the bottom of the lower pad 25, and an inner slider push rod 27 is disposed on the lower base plate 26 and can move up and down relative to the lower base plate 26, and the upper end of the inner slider push rod 27 passes through the lower pad 25 to connect the inner slider 22. When the inner slider 22 slides, the inner slider push rod 27 is driven to slide up and down. Since the inner slider push rod 27 can move up and down relative to the lower base plate 26 and pass through the lower pad 25, the inner slider push rod 27 is not easy to shake horizontally, so that the inner slider 22 slides more smoothly. There are two inner sliders 22, and two inner slider push rods 27 should be provided.

[0035] Preferably, a first cavity 261 is provided on the lower seat plate 26, and the lower end of the inner slider push rod 27 is located in the first cavity 261. A first reset elastic member 262 is provided between the lower end of the inner slider push rod 27 and the bottom of the first cavity 261. The provision of the first reset elastic member 262 can help the inner slider 22 to reset upward. When the inner slider 22 slides downward, it drives the inner slider push rod 27 to slide downward, and at this time, the first reset elastic member 262 in the first cavity 261 is compressed; when the downward pressure on the inner slider 22 is released, the first reset elastic member 262 rebounds and drives the inner slider push rod 27 and the inner slider 22 to slide upward. There are two inner slider push rods 27, the number of first cavities 261 should be two, and the number of first reset elastic members 262 is also two.

[0036] Preferably, an outer slider push rod 28 is provided on the lower seat plate 26, which can move up and down relative to the lower seat plate 26, and the upper end of the outer slider push rod 28 passes through the lower pad 25 to connect the outer slider 24. When the outer slider 24 slides, it drives the outer slider push rod 28 to slide up and down. Since the outer slider push rod 28 can move up and down relative to the lower seat plate 26 and pass through the lower pad 25, the outer slider push rod 28 is not easy to shake horizontally, so that the outer slider 24 slides more smoothly. If there are two outer sliders 24, two outer slider push rods 28 should be provided.

[0037] Furthermore, a second cavity 263 is provided on the lower seat plate 26, and the lower end of the outer slider push rod 28 is located in the second cavity 263. A second reset elastic member 264 is provided between the lower end of the outer slider push rod 28 and the bottom of the second cavity 263. The second reset elastic member 264 can help the outer slider 24 reset upward. When the outer slider 24 slides downward, it drives the outer slider push rod 28 to slide downward, and the second reset elastic member 264 in the second cavity 263 is compressed; when the downward pressure on the outer slider 24 is released, the second reset elastic member 264 rebounds and drives the outer slider push rod 28 and the outer slider 24 to slide upward. Two outer slider push rods 28 are provided, and correspondingly, two second cavities 263 and two second reset elastic members 264 are provided respectively.

[0038] Preferably, a groove 232 is provided at the position of the outer slider seat 23 near the outer slideway 231, and the groove 232 extends to the inner side of the outer slideway 231. A limit block 233 is provided in the groove 232, and the limit block 233 partially extends into the inner side of the outer slideway 231 to limit the downward sliding stroke of the outer slider 24. When the outer slider 24 slides down to contact the limit block 233, the outer slider 24 is restricted by the limit block 233 and cannot continue to slide downward, which can prevent the outer slider 24 from excessively squeezing the frame member 3, thereby preventing the thickness of the frame member 3 from becoming thinner. In fact, the limit block 233 can be set as a structure that can adjust the position up and down to adjust the downward sliding stroke of the outer slider 24, so as to adapt to the shaping of frame members 3 with different thicknesses.

[0039] Embodiment 2

[0040] See also Figure 3 and Figure 4 The shaping mechanism also includes an upper mold 1 arranged above the lower mold 2. The upper mold 1 includes an upper base plate 11 and an upper pad 12. The upper pad 12 is installed at the bottom of the upper base plate 11. Two pressure rods 13 are provided at the bottom of the upper pad 12. The pressure rods 13 correspond to the outer sliders 24 one by one. When the upper mold 1 and the lower mold 2 are molded together, the lower ends of the pressure rods 13 press against the outer sliders 24 to make the outer sliders 24 slide downward. In this embodiment, the upper mold 1 serves as a downward pressure structure. When the upper mold 1 and the lower mold 2 are molded together, the pressure rods 13 apply downward pressure to the outer sliders 24 to make the outer sliders 24 slide downward, and at the same time drive the frame member 3 to move downward and the inner slider 22 to slide downward. The outer slider 24 and the inner slider 22 squeeze the outer edge and the inner edge of the vertical edge 31 respectively to achieve the shaping of the metal frame of the mobile phone.

[0041] Preferably, the upper mold 1 further comprises a pressing plate 14, a guide post 15 is provided at the bottom of the upper pad 12, the pressing plate 14 is slidably arranged on the guide post 15, and the pressing plate 14 can slide relative to the pressing rod 13. When the upper mold 1 and the lower mold 2 are molded together, the lower end of the pressing rod 13 passes through the pressing plate 14 and presses against the outer slider 24, and the pressing plate 11 presses against the top surface of the horizontal edge 32 of the frame member 3. The arrangement of the pressing plate 11 makes the top surface of the horizontal edge 32 of the frame member 3 pressurized when the upper mold 1 and the lower mold 2 are molded together, which can drive the inner slider 22 to slide downward, and when the horizontal edge 32 of the frame member 3 contacts the top surface of the inner slider seat 21, the pressing plate 11 presses the upper edge of the horizontal edge 32 from top to bottom, and the inner slider seat 21 presses the lower edge of the horizontal edge 32 from bottom to top, which can make the horizontal edge 32 more flat.

[0042] Preferably, the guide pillar 15 is staggered with the inner slider seat 21, and the guide pillar 15 is staggered with the outer slider seat 23 to avoid interference between the guide pillar 15 and the inner slider seat 21 or the guide pillar 15 and the outer slider seat 23 when the upper mold 1 moves downward.

[0043] Preferably, a third resetting elastic member 16 is provided between the upper pad 12 and the pressing plate 14 , and the third resetting elastic member 16 can help the pressing plate 11 to reset.

[0044] When in use, first place the frame member 3 into the lower mold 2 so that the bottom surface of the horizontal edge 32 of the frame member 3 is placed on the top surface of the two inner slides 22, and then use the pressing machine to move the entire upper mold 1 downward to close the upper mold 1 and the lower mold 2. When the upper mold 1 moves downward, the pressure plate 11 first contacts the top surface of the outer slide 24. At this time, since a third reset elastic member 16 is provided between the upper pad 12 and the pressure plate 14 and the pressure plate 14 can slide relative to the guide column 15 and the pressure rod 13, when the upper mold 1 continues to move downward, the pressure plate 14 does not move, and the upper pad 12 moves toward the pressure plate 14 and compresses the third reset elastic member 16 until the lower end of the pressure rod 13 passes through the pressure plate 14 and contacts the outer slide 24. At the same time, the bottom surface of the upper pad 12 abuts against the top surface of the pressure plate 14. Then, the upper mold 1 continues to move downward, and the pressure rod 13 presses against the outer slide 24 to make the outer slide 24 and the outer slide top rod 2 8 slides downward, the second reset elastic member 264 is squeezed, and when the outer slider 24 slides downward until it contacts the vertical edge 31 of the frame member 3, it drives the entire frame member 3, the two inner sliders 22 and the two inner slider push rods 27 to move downward, and the first reset elastic member 262 is squeezed, so that the outer slider 24 squeezes the outer edge of the vertical edge 31 from the outside to the inside, and the inner slider 22 squeezes the inner edge of the vertical edge 31 from the inside to the outside, and then the mold 1 continues to move downward so that the top surface of the horizontal edge 32 abuts the pressing plate 11, at this time, the upper edge and lower edge of the horizontal edge 32 and the inner edge and outer edge of the vertical edge 31 are squeezed, and the entire frame member 3 is shaped. After the shaping is completed, the upper mold 1 moves upward to reset, and at this time the third reset elastic member 16 rebounds to drive the pressing plate 11 to reset, and the first reset elastic member 262 and the second reset elastic member 264 both rebound to drive the inner slider 22 and the outer slider 24 to reset.

[0045] Preferably, a clamping plate 17 is provided at the bottom of the upper pad 13, and the clamping plate 17 can limit the travel of the pressing plate 14 relative to the guide pillar 15. When the lower mold 2 moves downward until the lower end of the pressing rod 13 passes through the pressing plate 14 and contacts the outer slide 24, the bottom surface of the clamping plate 17 abuts against the top surface of the pressing plate 14, and the pressing plate 14 no longer moves relative to the guide pillar 15.

[0046] Preferably, the lower mold 2 further includes a plurality of feet 29 , which are disposed at the bottom of the lower seat plate 26 for supporting the lower seat plate 26 .

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
