Description

Technical Field

[0001] This utility model relates to the field of mobile phone casing injection molding, and in particular to a mobile phone casing injection mold. Background Technology

[0002] In our daily lives, mobile phones are an indispensable communication tool. However, with the development of society, mobile phones are becoming more and more expensive, and the materials have changed from plastic to glass and metal. At this time, it is necessary to protect the mobile phone. This protection is extremely important. This is where mobile phone cases come in, which are used to protect the mobile phone from external scratches and to cushion the damage caused by dropping the mobile phone.

[0003] According to the Utility Model No. CN215095435U, a mobile phone shell injection mold is disclosed, which includes a mold body for injection molding of mobile phone shell. The mold body is composed of a matching upper mold and a lower mold. A lower clamp with a lower pressure mold is embedded in the surface of the lower mold. A water tank with unidirectional conveying is provided inside the lower mold located below the lower clamp. A plurality of heat sinks are also provided on the side of the lower mold. A heat-conducting plate is sandwiched between the heat sink and the lower mold.

[0004] Based on the aforementioned patent, a combination of a water tank and a radiator is used to cool the lower mold. The continuously flowing water in the water tank makes large-area contact with the interior of the lower mold, rapidly reducing the internal temperature using the temperature difference. Simultaneously, the surrounding heat is transferred to the radiator by heat-conducting plates, achieving rapid cooling and improving the molding effect of the phone case after injection molding. However, the phone case cannot automatically detach after cooling and requires manual removal, which is time-consuming, labor-intensive, and reduces production efficiency. To address this technical problem, this application proposes a phone case injection mold. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 2 , Figure 3 and Figure 4 This utility model provides an embodiment of a mobile phone case injection mold, including an injection molding box 1. First fixing blocks 2 are fixedly connected to the left sides of both the front and rear ends of the inner wall of the injection molding box 1. A left clamp 3 is fixedly connected to the opposite ends of the first fixing blocks 2. A first movable rod 4 is movably connected to the middle of the left clamp 3. A push block 5 for ejecting the cooled mobile phone case from the inside of the left clamp 3 is fixedly connected to the right end of the first movable rod 4. A cross 6 is fixedly connected to the left end of the first movable rod 4. Multiple second fixing blocks 7 are fixedly connected to the outer wall of the left clamp 3. A first fixing block 6 is movably connected to the middle of each of the second fixing blocks 7. The left end of each of the two movable rods 8 is fixedly connected to the right end of the cross 6. The right end of each of the two movable rods 8 is fixedly connected to a disc 9. The outer wall of each of the two movable rods 8 is provided with a spring 10, which is located between the second fixed block 7 and the disc 9. The right side of both the front and rear ends of the inner wall of the injection molded box 1 is provided with a limit groove 19. The inner wall of each limit groove 19 is movably connected with an ear plate 12. The opposite ends of the ear plates 12 are fixedly connected to a right clamp 11. The outer wall of the right clamp 11 is provided with multiple stops 13. The left end of each stop 13 is provided with a circular groove 14, and the disc 9 matches the circular groove 14.

[0027] Specifically, when the disc 9 moves to the left, it drives the cross 6 to move to the left through the second movable rod 8 fixedly connected to it. The cross 6 drives the push block 5 to move to the left through the first movable rod 4, causing the push block 5 to retract into the interior of the left clamp 3. During this process, the disc 9 compresses the spring 10, causing the spring 10 to generate potential energy. When the leftward force on the disc 9 disappears, the potential energy of the spring 10 is released, thereby causing the push block 5 to move to the right, thus realizing the function of automatically pushing out the phone case.

[0028] Reference Figure 1 Figure 3 and Figure 4A groove plate 15 is provided on the right side of the right clamp 11. The front and rear ends of the groove plate 15 are fixedly connected to the inner wall of the injection molding box 1. The inner wall of the groove plate 15 is rotatably connected to the groove plate 15. Threaded blocks 16 are threadedly connected to the outer walls of the front and rear sides of the groove plate 15. A connecting plate 17 is rotatably connected to the left end of the threaded block 16. The other end of the connecting plate 17 is rotatably connected to the right end of the right clamp 11. A motor 18 is fixedly connected to the right front end of the injection molding box 1. The drive shaft of the motor 18 is fixedly connected to the front end of the bidirectional screw 28.

[0029] Specifically, the motor 18 is started, at which point the motor 18 comes into play, causing the threaded blocks 16 on both the front and rear sides to move towards each other on the inner wall of the slot plate 15. As the threaded blocks 16 move, the connecting plate 17, which is rotatably connected to them, gradually unfolds and straightens. Driven by the connecting plate 17, the right clamp 11, which is rotatably connected to the connecting plate 17, slowly moves to the left, eventually fitting tightly together with the left clamp 3, thus forming a sealed space.

[0030] Reference Figure 1 , Figure 2 and Figure 5 A heating injection molding machine 22 is fixedly connected to the top left side of the injection molding box 1. The bottom end of the heating injection molding machine 22 is connected to the top end of the left clamp 3. A material hopper 20 is fixedly connected to the top right side of the injection molding box 1. A connecting pipe 21 is fixedly connected to the left end of the material hopper 20. The other end of the connecting pipe 21 is fixedly connected to the top end of the heating injection molding machine 22. A cold air fan 24 is fixedly connected to both the front and rear ends of the injection molding box 1. A filter screen 23 is fixedly connected to both the left and right ends inside the injection molding box 1. A support platform 25 is fixedly connected to the bottom end of the injection molding box 1. An inclined platform 26 is set inside the support platform 25. Support legs 27 are fixedly connected to the four corners of the bottom end of the support platform 25.

[0031] Specifically, the cooling fan 24 enables rapid cooling of the phone case, which helps improve processing efficiency. The cooling fan 24 can prevent impurities from entering the injection molding box 1, thus avoiding impurities from affecting the quality of the phone case injection molding process. The inclined platform 26 facilitates the automatic detachment of the phone case, allowing it to slide out along the inclined surface for easy material discharge.

[0032] Working principle: When in use, motor 18 is started first. Motor 18 drives the threaded blocks 16 on the front and rear sides to move towards each other along the inner wall of the groove plate 15, thereby causing the connecting plate 17, which is rotatably connected to the threaded blocks 16, to unfold and straighten. Then, it drives the right clamp 11, which is rotatably connected to the connecting plate 17, to move to the left and fit tightly with the left clamp 3 to form a sealed space. The heated injection molding machine 22 injects the hot melt raw material into its interior. During the process of the right clamp 11 moving to the left, the cooperation of the disc 9, the stop block 13 and the circular groove 14 drives the second movable rod 8 and the cross 6 to move to the left. The cross 6 drives the push block 5 to move to the left through the first movable rod 4, causing the first movable rod 4 to retract into the interior of the left clamp 3. The disc 9 moves to the left and squeezes the spring 10, causing the spring 10 to generate potential energy. After the phone case cools down, the motor 18 is started in the opposite direction, causing the right clamp 11 to move to the right. Under the action of the spring 10, the push block 5 moves to the right, pushing the phone case out, completing the automatic removal of the phone case.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
