Description

Technical Field

[0001] The invention relates to the technical field of mobile phone cases and preparation equipment, in particular to a triple-proof mobile phone case and a precision injection mold thereof. Background Art

[0002] A triple-proof mobile phone case refers to a mobile phone case with three protective functions: dustproof, waterproof, and drop-proof. These mobile phone cases usually use special materials and designs, and can protect mobile phones from damage caused by dust, moisture, and falls in harsh outdoor environments. When preparing the triple-proof mobile phone case, corresponding injection molds are usually used to improve the preparation efficiency of the triple-proof mobile phone case.

[0003] At present, the existing triple-proof mobile phone case injection mold cannot improve the thermal conductivity of the triple-proof mobile phone case when it is in use, because the triple-proof mobile phone case will completely wrap the mobile phone when in use, thereby ensuring that dust and water from the outside will not enter the inside of the mobile phone case and cause damage to the mobile phone. Therefore, it will also cause the disadvantage that heat cannot be dissipated quickly. Although the triple-proof mobile phone case can use its own thermal conductivity efficiency to guide heat to the outside and dissipate heat for the mobile phone in normal use, its thermal conductivity efficiency is limited. When the mobile phone is playing games, used in summer or working for a long time, the temperature of the mobile phone will gradually increase, and the limited thermal conductivity efficiency cannot dissipate the heat generated when the mobile phone is running.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing three-proof mobile phone cases and their precision injection molds on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which cannot achieve the desired effect.

The processing mechanism 3 is used in conjunction with a heat conduction mechanism 2. The processing mechanism 3 can increase the solidification rate of the coating on the surface of the collection protective case.

[0047] As a further limitation of the processing mechanism 3 of the present invention, the processing mechanism 3 includes a support plate 302, the bottom surface of the support plate 302 is fixedly connected to the upper surface of the bottom plate 1, the front surface of the support plate 302 is fixedly connected to the back of the support block 2207, the inner wall of the support plate 302 is rotatably connected with a rotating shaft 310, and the end of the rotating shaft 310 close to the injection molding device body 11 is fixedly connected to the rotating block 301, and the front of the rotating block 301 is provided with two circular openings 309, and the inner wall of the rotating block 301 is respectively fixedly connected with a first sealing ring 315 and a fixed ring 311, wherein the interior of one of the circular openings 309 is slidably connected with an extrusion block 313, and the outer surface of the extrusion block 313 is fixedly connected with a second sealing ring 314, and the outer surface of the second sealing ring 314 contacts the inner wall of the rotating block 301, and the back of the second sealing ring 314 and the front of the fixed ring 311 are fixedly connected with two force springs 312, and the end of the rotating shaft 310 away from the injection molding device body 11 is fixedly connected with a first gear 305, The front of the support plate 302 is fixedly connected to a heating bin 304, the right side of the heating bin 304 is fixedly connected to the left side of the cooling water tank 2211, the end of the input pipe 2209 close to the heating bin 304 penetrates into the interior of the heating bin 304, the outer surface of the input pipe 2209 is fixedly connected to a third solenoid valve 317, the inner wall of the heating bin 304 is fixedly connected to five heating wires 308, the outer surface of the first output pipe 2208 is fixedly connected to a second output pipe 303, the outer surface of the second output pipe 303 is fixedly connected to a fourth solenoid valve 316, the outer surface of the second output pipe 303 is fixedly connected to the inner wall of the support plate 302, the upper surface of the heating bin 304 is fixedly connected to a stepper motor 307, the output end of the stepper motor 307 is fixedly connected to a second gear 306, the outer surface of the second gear 306 is meshed with the outer surface of the first gear 305, and a processing mechanism 3 is provided, by which the mobile phone shell 2101 after spraying can be dried and the material return can be assisted.

[0049] Example 3: Please refer to Figure 1 , Fig.10 , Fig.11 and Fig.12 The present invention provides a technical solution: a triple-proof mobile phone case. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0050] As a further limitation of the heat-conducting mechanism 2 of the present invention, the mobile phone shell 2101 includes a mobile phone shell 2101, which is arranged above the heat-conducting mechanism 2, and the inner wall of the mobile phone shell 2101 is fixedly connected to a copper frame 2102, and the inner wall of the copper frame 2102 is rotatably connected to eleven rotating shafts 2104, and the outer surface of each rotating shaft 2104 is fixedly connected to a heat-dissipating copper plate 2103, and the outer surface of each heat-dissipating copper plate 2103 is in contact with the inner wall of the copper frame 2102, and the mobile phone shell 2101 includes a first thermoplastic epoxy resin layer 2 105, a first thermoplastic epoxy resin layer 2105 is fixedly connected to a metal powder layer 2106 on the front side, a carbon nanotube layer 2107 is fixedly connected to the metal powder layer 2106 on the front side, a graphite layer 2108 is fixedly connected to the carbon nanotube layer 2107 on the front side, a ceramic particle layer 2109 is fixedly connected to the graphite layer 2108 on the front side, an aluminum oxide layer 2110 is fixedly connected to the aluminum oxide layer 2110 on the front side, and a second thermoplastic epoxy resin layer 2111 is fixedly connected to the aluminum oxide layer 2110 on the front side.

[0051] The specific implementation of this embodiment is as follows: when in use, the copper frame 2102 can be placed inside the fixed mold 2204 first, and the gear pump 2206 can be controlled to run for coating work, and at this time the first solenoid valve 2217 and the second solenoid valve 2216 are in an open state, while the third solenoid valve 317 and the fourth solenoid valve 316 are in a closed state, so that the outside air will enter the interior of the gear pump 2206 through the input pipe 2209. When the air enters the interior of the gear pump 2206, it will rotate at a high speed inside the gear pump 2206 and will be discharged from the first output pipe 2208 to the storage material. The inside of the box 2201, at this time, the pressure inside the storage box 2201 is greater than the outside, so the graphene heat dissipation paint stored in the storage box 2201 will be sprayed to the surface of the heat dissipation copper plate 2103 inside the copper frame 2102 through the spray pipe 2210 after being pressurized, thereby achieving the purpose of spraying, wherein the graphene heat dissipation paint is a paint made by utilizing the high thermal conductivity and high thermal emissivity characteristics of graphene, which can effectively improve the heat dissipation capacity of the surface of an object. This paint can be applied to the surface of high-temperature devices and equipment, transfer heat to the coating and transfer it to the outside with high radiation heat dissipation capacity, achieving efficient heat transfer or cooling effect;

[0052] When the paint is sprayed, the gear pump 2206 and the heating wire 308 can be controlled to operate again. The operation of the heating wire 308 will increase the temperature inside the heating chamber 304, and control the first solenoid valve 2217 and the second solenoid valve 2216 to be closed, while the third solenoid valve 317 and the fourth solenoid valve 316 are opened. At this time, the power generated by the operation of the gear pump 2206 will enter the second output pipe 303 through the input pipe 2209, and the second output pipe 303 will guide the hot air to the inside of a circular opening 309 opened on the front of the rotating block 301. Through the guidance of the circular opening 309, the hot air can be guided to the surface of the heat dissipation copper plate 2103 that has just been sprayed with paint, thereby accelerating the solidification of the paint. During the above process, the two control units can be operated synchronously. The injection molding device body 11 is in operation, and the operation of the injection molding device body 11 will push the movable mold 2222 to move closer to the fixed mold 2204 until the two are spliced ​​together, and then the injection molding device body 11 is used to inject a liquid containing metal powder, carbon nanotubes, graphite, ceramic particles and thermoplastic epoxy resin into the interior of the fixed mold 2204 and into the interior of the movable mold 2222 and the fixed mold 2204 to complete the injection molding, wherein the presence of metal powder, carbon nanotubes, graphite, ceramic particles and thermoplastic epoxy resin can ensure that the mobile phone shell 2101 has flexibility and ductility, and quickly guide most of the heat generated on both sides of the mobile phone to the copper frame 2102, while another small part of the heat can be discharged to the outside by itself, thereby accelerating the heat dissipation;

[0053] After the injection molding of the mobile phone shell 2101 is completed, the cooling water tank 2211 and the water pump 2212 are controlled to operate. The power generated by the operation of the water pump 2212 will guide the condensed water inside the cooling water tank 2211 to enter the water pump 2214, and return to the inside of the cooling water tank 2211 after circulating through the water outlet pipe 2205 for one cycle. In this process, the condensed water inside the water outlet pipe 2205 will take out the heat generated during the injection molding, thereby achieving the purpose of rapid solidification of the mobile phone shell 2101, and the water source with heat will return to the inside of the cooling water tank 2211 for cooling after circulation. The cooling water tank 2211 is an advanced circulating water cooling equipment, which can be widely used in supporting other electrical and mechanical equipment that require circulating water cooling. Its working principle is that the cold water stored in the water tank is sucked into the circulation system by the water pump 2212, and passes through the equipment to be cooled. After the mobile phone shell 2101 has cooled down, the stepper motor 307 is driven to operate, and the second gear 306 is driven to rotate by the stepper motor 307. The meshing relationship between the second gear 306 and the first gear 305 can be used to drive the rotating shaft 310 to rotate, so that the other circular opening 309 can be rotated to a position corresponding to the air outlet of the second output pipe 303. At this time, the gear pump 2206 can operate to deliver air to the surface of the second sealing ring 314, so that the second sealing ring 314 and the extrusion block 313 can be pushed to move under the action of air pressure until the extrusion block 313 is pushed out of the range of the rotating block 301, and the mobile phone shell 2101 that has been injection molded is pushed out for auxiliary material unloading.

[0054] When the mobile phone case 2101 is in use, the heat generated by the back of the mobile phone will be guided to the heat dissipation copper plate 2103 through the copper frame 2102, and when there is a fan near the device or other conditions that can drive rapid air circulation, the heat dissipation copper plate 2103 can be rotated ninety degrees to expand the heat dissipation copper plate 2103 to increase the heat dissipation area, and the rotation axis 2104 is not in the middle of the heat dissipation copper plate 2103, but is slightly offset to ensure that the heat dissipation copper plate 2103 is divided into two areas of different areas by the rotation axis 2104 after expansion, of which the smaller area is the larger area. Three sides of an area will be in contact with the copper frame 2102, and a larger area will extend out of the horizontal area of ​​the copper frame 2102, thereby increasing the contact area between the heat dissipation copper plate 2103 and the air, allowing the heat to be dissipated more quickly. Part of the heat on both sides of the mobile phone will be guided into the copper frame 2102 by the outer shell mixed with metal powder, carbon nanotubes, graphite, ceramic particles and thermoplastic epoxy resin, and the other part will contact the air under the condition of heat conduction of the outer shell itself and dissipate in the atmosphere, thereby improving the heat dissipation efficiency of the mobile phone case 2101 and extending the service life of the mobile phone.
