[0002] A display frame generally refers to the framework used to secure and protect screen components such as liquid crystal displays (LCDs) or organic light-emitting diode displays (OLEDs). The frame's design ensures the display is securely mounted on the device and provides a degree of protection from external factors like dust and moisture. It also reduces damage from drops and collisions, enhancing the device's durability and lifespan.

[0003] The manufacturing of display screen frames primarily involves heating the material to a certain temperature, softening it, and injecting it into a mold through injection molding or compression molding.

DETAILED DESCRIPTION

[0019] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the present invention are shown. However, the present invention can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully convey the scope of the invention to those skilled in the art.

[0020] Example:

[0021] A display screen plastic frame injection mold, such as Figures 1-6 As shown, it includes a fixed frame 1, an electric slide rail 2, a lower mold 3, an injection molding machine 4, an upper mold 5, a cooling box 6, a water pump 7, a cooling water pipe 8, a material taking mechanism and a cooling fan 18. The left and right sides of the fixed frame 1 are fixedly connected with the electric slide rail 2, the lower mold 3 is fixedly connected to the electric slide rail 2, the top of the lower mold 3 is provided with a mold groove, the injection molding machine 4 is fixedly connected between the sliders of the left and right electric slide rails 2, the bottom of the injection molding machine 4 is fixedly connected to the upper mold 5, a cooling box 6 and a water pump 7 are installed on the top of the fixed frame 1, the water pump 7 is located on the inner wall of the cooling box 6, the lower mold 3 is fixedly connected with a cooling water pipe 8, one end of the cooling water pipe 8 is fixedly connected to the water pump 7, and the other end of the cooling water pipe 8 is communicated with the cooling box 6, the upper mold 5 and the lower mold 3 are connected with a material taking mechanism, and two cooling fans 18 are installed between the left and right electric slide rails 2.

[0022] When the display screen frame is being injection molded, the injection molding machine 4 is driven downward by the electric slide 2 to make the upper mold 5 enter the mold groove of the lower mold 3, and then the melted material is injected into the mold groove by the injection molding machine 4. Under the extrusion of the upper mold 5, the melted material is completely fitted into the mold groove, and the coolant in the cooling box 6 is pumped into the cooling water pipe 8 by the water pump 7. The cooling water pipe 8 is close to the mold groove of the lower mold 3, so that the coolant can absorb the heat of the melted material, thereby cooling the material in the mold groove through the cooling water pipe 8, so that the material is quickly cooled and shaped, and then the injection molding machine 4 is driven upward by the electric slide 2 to make the upper mold 5 away from the lower mold 3, and then the display screen frame is taken out to complete an injection molding process, which can improve the injection molding efficiency of the display screen frame. At the same time, the material in the mold groove is further cooled by the cooling fan 18, thereby improving the cooling efficiency of the injection mold.

[0023] like Figure 1 、 Figure 3 、 Figure 5 and Figure 6As shown, it also includes a rotating frame 9, a servo motor 10, a connecting gear 11, an internal gear 12 and a stirring plate 13. The top of the cooling box 6 is rotatably connected to the rotating frame 9, and the top of the rotating frame 9 is fixedly connected to the internal gear 12. The servo motor 10 is installed on the fixed frame 1, and the output shaft of the servo motor 10 is fixedly connected to the connecting gear 11. The connecting gear 11 is meshed with the internal gear 12. Six stirring plates 13 are fixedly connected to the bottom of the rotating frame 9. The stirring plates 13 are all provided with bubble holes. The stirring plates 13 are all located inside the cooling box 6. When the coolant is used for a period of time, the temperature of the coolant will increase. The servo motor 10 drives the connecting gear 11 on it to rotate. Under the meshing action of the connecting gear 11 and the internal gear 12, the rotating frame 9 is rotated, so that the stirring plates 13 stir the coolant in the cooling box 6, accelerating the heat dissipation rate of the coolant. The bubble holes can help form a flow path for the coolant, promote convection inside the coolant, accelerate the heat transfer of the coolant, further accelerate the heat dissipation of the coolant, and ensure the cooling efficiency of the coolant.

[0024] like Figure 1 As shown, a refrigerator 19 is also included, and the bottom of the cooling box 6 is fixedly connected to the refrigerator 19, and the cooling pipe of the refrigerator 19 is connected to the cooling box 6. The refrigerator 19 can directly cool the coolant, further ensuring the cooling efficiency of the coolant.

[0025] like Figures 1-4 As shown, the material taking mechanism includes an ejector frame 14, a connecting plate 141, a first connecting spring 15, a push rod 16 and a second connecting spring 17. The connecting plates 141 are slidably connected to the left and right sides of the lower mold 3. The top of the connecting plate 141 is fixedly connected to the ejector frame 14. The ejector frame 14 is located in the mold groove. The first connecting spring 15 is fixedly connected between the ejector frame 14 and the connecting plate 141. A push rod 16 is installed on the injection molding machine 4. A second connecting spring 17 is connected between the push rod 16 and the injection molding machine 4. The elastic force of the second connecting spring 17 is greater than the elastic force of the first connecting spring 15. The elastic force of the first connecting spring 15 is greater than the adhesion force of the display screen rubber frame in the mold groove. Initially, the first connecting spring 15 and the second connecting spring 17 are both in normal state. When the upper mold 5 and the injection molding machine 4 move downward and approach the lower mold 3, the ejector rod 16 squeezes the ejector frame 14, and the ejector frame 14 moves downward into the mold cavity. The first connecting spring 15 is stretched, and the second connecting spring 17 is slightly compressed, and the connecting plate 141 moves downward. During injection molding, the melted material is located at the top of the ejector frame 14. When the injection molding is completed, the injection molding machine 4 is driven upward by the electric slide rail 2, and the ejector rod 16 moves away from the ejector frame 14. The first connecting spring 15 and the second connecting spring 17 are restored to their original state, and the ejector frame 14 ejects the display screen plastic frame from the mold cavity, thereby facilitating the removal of the display screen plastic frame and further improving the processing efficiency of the injection mold.
