DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 , Figure 2 and Figure 3 A carbon fiber and glass fiber mobile phone back cover molding device in this embodiment includes a base 1, support legs are fixedly installed on the bottom surface of the base 1, support columns 2 are fixedly installed on the top surface of the base 1, and a top plate 3 is fixedly installed on the other ends of the four support columns 2. An upper mold 4 and a lower mold 5 are arranged between the base 1 and the top plate 3 from top to bottom. A molding block 6 is fixedly installed on the lower surface of the upper mold 4, a molding groove is opened on the upper surface of the lower mold 5, and an extrusion block 7 is fixedly installed on the inner bottom wall of the molding groove, and a fixing groove is opened on the upper surface of the extrusion block 7, and a demolding component extending to the outside of the lower mold 5 is arranged inside the fixing groove.

[0020] It can be understood that an injection port is provided on the upper surface of the upper mold 4 , the other end of the injection port extends to the bottom end of the forming block 6 , and an injection pipe is fixedly installed on the other end of the injection port.

[0021] It should be noted that a groove is provided on the lower surface of the forming block 6. When the upper mold 4 and the lower mold 5 are closed, there is a certain gap between the forming block 6 and the extrusion block 7. The gap space is the thickness of the back cover of the mobile phone.

[0022] See also Figure 1 and Figure 3 In this embodiment, the demolding assembly includes a demolding plate 8 arranged inside the fixed groove, and a connecting rod 9 extending to the bottom of the lower mold 5 is fixedly installed on the lower surface of the demolding plate 8, and a push plate 10 is fixedly installed on the other end of the connecting rod 9. Spring telescopic rods 11 are fixedly installed on the top surface of the push plate 10 all around, and the other ends of the four spring telescopic rods 11 are fixedly connected to the lower surface of the lower mold 5.

[0023] It should be noted that a plurality of electric push rods 12 are fixedly mounted on the lower surface of the base 1 and on both sides of the push plate 10 , and the movable ends of the plurality of electric push rods 12 extend to the top of the base 1 and are fixedly mounted with support plates 13 .

[0024] When the back cover of the mobile phone is formed, the electric push rod 12 is started, so that the support plate 13 is away from the bottom of the lower mold 5, so that the lower mold 5 moves downward under the influence of weight, thereby squeezing the push plate 10, so that the push plate 10 can drive the stripping plate 8 to move upward through the connecting rod 9, thereby lifting the product, making it easier for the staff to take it out from the lower mold 5.

[0025] See also Figure 1 and Figure 3 In this embodiment, first mounting blocks 14 are provided on both side surfaces of the upper mold 4, and second mounting blocks 15 are provided on both side surfaces of the lower mold 5. The two first mounting blocks 14 and the two second mounting blocks 15 are fixedly mounted on the corresponding side surfaces of the upper mold 4 and the lower mold 5 by bolts. The first mounting blocks 14 and the second mounting blocks 15 are installed by bolts, so that the staff can replace the upper mold 4 and the lower mold 5, which is convenient for the staff to manufacture products of different sizes.

[0026] See also Figure 1 and Figure 2 In this embodiment, protective boxes are fixedly installed on the upper surface of the top plate 3 and on both sides of the upper mold 4, and motors 16 are fixedly installed on the inner walls of the two protective boxes. The output ends of the two motors 16 are fixedly installed with screw rods 17 whose one end extends to the bottom of the top plate 3 and is rotatably connected to the upper surface of the base 1, and the two first mounting blocks 14 are threadedly sleeved on the corresponding surfaces of the screw rods 17.

[0027] Among them, guide rods 18 are fixedly installed on the surface of the side opposite to the base 1 and the top plate 3 and on both sides of the lower mold 5, the two first mounting blocks 14 are slidably sleeved on the corresponding surfaces of the guide rods 18, and the two second mounting blocks 15 are slidably sleeved on the corresponding surfaces of the guide rods 18.

[0028] The motor 16 drives the screw rod 17 to rotate, so that the screw rod 17 can drive the first mounting block 14 to move, and the first mounting block 14 can drive the upper mold 4 to move.

[0029] The working principle of the above embodiment is as follows: after the product is formed, the electric push rod 12 is started, so that the support plate 13 is away from the bottom of the lower mold 5, so that the lower mold 5 moves downward under the influence of weight, thereby squeezing the push plate 10, so that the push plate 10 can drive the stripping plate 8 to move upward through the connecting rod 9, thereby lifting the product, making it easier for the staff to take it out from the lower mold 5. Through the above operation, the staff can complete the demoulding of the product without knocking on the lower mold 5, avoiding the size, shape and quality of the product being affected.

[0030] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
