Technical Field

[0001] This utility model relates to the field of mobile phone frame forming and processing technology, and more specifically, to a carbon fiber mobile phone frame forming mechanism. Background Technology

[0002] Carbon fiber mobile phone frame forming mechanism is a special equipment used to process carbon fiber prepreg (CFRP) into the shape of mobile phone frame. It is usually achieved by combining hot pressing, compression molding or high pressure RTM (resin transfer molding) and other processes.

The mold is used to press and heat the stacked carbon fiber prepreg. After the hot pressing is completed and cooled, the carbon fiber phone frame is formed. However, after the carbon fiber phone frame is processed, it is not convenient for workers to remove it from the mold. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0025] Please see Figure 1-5 In this utility model: a carbon fiber mobile phone frame forming mechanism includes an upper mold 1 and a lower mold 2. The top of the upper mold 1 is connected to a lifting mechanism. The top of the lower mold 2 has a pressing groove 3, which is square in shape. The bottom of the upper mold 1 is fixedly connected to a pressing frame 4 that matches the pressing groove 3. The interior of the lower mold 2 has a circular cavity 5. A lifting plate 6 is slidably connected to the inner wall of the circular cavity 5. Two sliding rods 7 are fixedly connected to the inner wall of the circular cavity 5. The lifting plate 6 is respectively sleeved on the two sliding rods 7 and slidably connected to them. A spring 8 is sleeved on each of the two sliding rods 7. Two vertical rods 9 are fixedly connected to the top of the lifting plate 6. The top ends of the two vertical rods 9 penetrate the lower mold 2 and extend into the interior of the pressing groove 3. A top ring 10 is slidably connected to the inner wall of the pressing groove 3. The bottom of the top ring 10 is fixedly connected to the two vertical rods 9 respectively. An operating lever 11 is fixedly connected to the top of the lifting plate 6. The top of the operating lever 11 extends through and to the top of the lower mold 2. A heating and cooling mechanism 12 is provided on the lower mold 2. The heating and cooling mechanism 12 includes an outer channel 121 and an inner channel 122. Both the outer channel 121 and the inner channel 122 are opened inside the lower mold 2. The outer channel 121 and the inner channel 122 are arranged in a U-shape. The pressure groove 3 is located between the outer channel 121 and the inner channel 122. The bottom of the outer channel 121 and the inner channel 122 are respectively connected to the liquid inlet pipe 123 and the liquid outlet pipe 124. An oil temperature controller 125 is provided on the back of the lower mold 2. The liquid outlet and the liquid inlet of the oil temperature controller 125 are respectively connected to the outer channel 121 and the inner channel 122. The outer channel 121 and the inner channel 122 are connected by a conduit 126.

[0026] In this invention, during use, the required size of rigid carbon fiber prepreg for the carbon fiber phone frame is first evenly stacked in the pressing groove 3. After all the rigid carbon fiber prepreg is placed inside the pressing groove 3, the topmost rigid carbon fiber prepreg will be lower than the top of the lower mold 2. Then, the upper mold 1 is lowered by the lifting mechanism, and the upper mold 1 will drive the pressing frame 4 to be inserted into the pressing groove 3. Next, the pressing frame 4 will squeeze the rigid carbon fiber prepreg, and the rigid carbon fiber prepreg will push the top ring 10 down along the inner wall of the pressing groove 3. During the process, the vertical rod 9 will drive the lifting plate 6 down and compress the two springs 8 until the bottom of the top ring 10 is flush with the inner bottom of the pressing groove 3. After wall contact, the rigid carbon fiber prepreg is squeezed between the pressure frame 4 and the top ring 10. As the pressure frame 4 descends, it further compresses the multiple stacked rigid carbon fiber prepregs. Then, the oil temperature controller 125 is turned on, and the oil temperature controller 125 injects heated oil from the outlet into the inlet pipe 123. The oil first enters the outer channel 121, flows in the outer channel 121, and flows into the inner channel 122 through the conduit 126. The oil then flows in the inner channel 122 and flows into the oil temperature controller 125 through the outlet pipe 124 and the inlet, thus allowing the oil to circulate between the oil temperature controller 125, the outer channel 121, and the inner channel 122. The oil circulates in channel 122, heating the lower mold 2 during circulation. This heating, in turn, heats the rigid carbon fiber prepreg, raising it to a suitable temperature. After holding the prepreg at this temperature for a period, the prepreg is hot-extruded into the desired carbon fiber phone frame. After hot pressing, the oil temperature controller 125 cools the oil, thus cooling the formed carbon fiber phone frame. Once cooled, the lifting mechanism reverses, causing the upper mold 1 to rise. At this point, the carbon fiber phone frame is no longer compressed by the pressure frame 4. At this point, the spring force of spring 8 will be released, and spring 8 will drive the lifting plate 6 to rise. The lifting plate 6 will drive the top ring 10 to rise through the vertical rod 9. After the top ring 10 rises, it will drive the carbon fiber mobile phone frame to rise along the pressing groove 3, thereby completing the demolding of the carbon fiber mobile phone frame. Until the spring force of spring 8 is completely released, the carbon fiber mobile phone frame is still in the pressing groove 3. The worker can drive the lifting plate 6 to rise by pulling the operating rod 11. Then the vertical rod 9 will drive the top ring 10 to rise. The top ring 10 will push the carbon fiber mobile phone frame out of the pressing groove 3. The worker can then take out the formed carbon fiber mobile phone frame, thereby completing the unloading of the carbon fiber mobile phone frame.

[0027] Please see Figure 3 and 4 The inner bottom wall of the cavity 5 is provided with a circular groove 13, and a circular disk 14 is threadedly connected to the inner wall of the circular groove 13. The top of the circular disk 14 is in contact with the spring 8 and the slide rod 7 respectively.

[0028] In this invention, when the spring 8 loses its strong elasticity after prolonged use, the user can rotate the disc 14 to remove it from the groove 13, and then replace the spring 8, thereby maintaining the elasticity of the spring 8 and improving the stability of the device.

[0029] Please see Figure 1-5 The top of the operating lever 11 is provided with an operating groove 15, which is arranged in a ring shape.

[0030] In this invention, the operation slot 15 makes it easier for the user to pull the operation lever 11 upwards, thereby improving the practicality of the device.

[0031] Please see Figure 1-3 The lower mold 2 has two fixedly connected limit rods 16 at its top, and the upper mold 1 has two limit holes 17 at its bottom that are adapted to the limit rods 16.

[0032] In this invention, the limiting rod 16 and the limiting hole 17 can limit the upper mold 1 when the upper mold 1 descends and closes with the lower mold 2, thereby improving the accuracy of the closing of the upper mold 1 and the lower mold 2.

[0033] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
