[0002] Laptop casings not only protect internal components but also significantly impact heat dissipation, appearance, and weight. They are typically made of metal, plastic, or a combination of both. Metal-plastic composites offer a solution that balances performance, cost, and design by leveraging the complementary strengths of the two materials to achieve a balance between lightweight, high strength, heat dissipation, and signal compatibility.
[0003] In the processing of metal and plastic composite molded shells, the material is often shaped by the closed extrusion of the upper and lower dies. However, in actual production, the extrusion pressure of the upper and lower dies is too high, which causes local deformation and surface scratches on the metal shell, thus affecting the product yield and appearance quality. To address this, a hot pressing molding device for notebook shells is proposed. Utility Model Content

[0028] like Figures 1 to 6As shown, a hot pressing forming apparatus for a notebook casing includes: a worktable 1, with a guide frame 103, a sliding plate 101, and a telescopic rod 102 sequentially arranged on the top of the worktable 1, the sliding plate 101 sliding outside the guide frame 103, an upper mold 104 on the side of the sliding plate 101 facing the worktable 1, and a lower mold 105 correspondingly arranged on the worktable 1, the upper mold 104 being connected to the sliding plate 101; and a support mechanism, disposed outside the worktable 1, for providing support for the casing, the support mechanism including a guide 2 and a buffer 3, the guide 2 being disposed outside the worktable 1 for guiding the movement direction of the lower mold 105, and the buffer 3 being disposed inside the guide 2 for supporting the lower mold 105, the guide 2 cooperating with the buffer 3 to control the pressure between the upper mold 104 and the lower mold 105, specifically, in When processing the outer shell, the outer shell to be processed is first placed on top of the lower mold 105. Then, the upper mold 104 is controlled to contact the lower mold 105 through the cooperation of the telescopic rod 102 and the sliding plate 101, so that the upper mold 104 cooperates with the lower mold 105 to perform thermoforming of the laptop shell. During the contact between the upper mold 104 and the lower mold 105, the pressure between the upper mold 104 and the lower mold 105 is controlled through the cooperation of the guide 2 and the buffer 3 to avoid excessive pressure between the upper mold 104 and the lower mold 105 causing damage to the laptop shell. The upper mold 104 and the sliding plate 101 can be connected by connecting pins or bolts, which facilitates the replacement of the upper mold 104 during use. The workbench 1 is also equipped with a hydraulic pump for providing power to the telescopic rod 102 and a control box for controlling the telescopic rod 102.
[0029] like Figures 1 to 6 As shown, the guide 2 includes a connecting block 201, which is disposed on the outside of the workbench 1 and has an opening on one side. The opening direction of the connecting block 201 is parallel to the height direction of the workbench 1. The lower mold 105 slides inside the connecting block 201. The lower mold 105 is provided with a first spring 202 on the side opposite to the connecting block 201. There are multiple first springs 202. Specifically, during use, the connecting block 201 guides the lower mold 105 during its movement to ensure that the lower mold 105 can slide stably inside the connecting block 201. The first springs 202 can provide a pushing force to the lower mold 105 during use, thereby providing the power to reset the lower mold 105 after the laptop shell is processed.
[0030] like Figures 1 to 6As shown, the buffer component 3 includes a support column 301, which is disposed inside the connecting block 201 and is hollow inside. A sliding column 302 is slidably connected inside the support column 301, and the sliding column 302 is T-shaped. One end of the sliding column 302 passes through the support column 301 and is connected to the lower mold 105. A fixing pipe 306, a pressure relief valve 303, and a storage tank 304 are respectively provided on the outside of the support column 301. The fixing pipe 306 is connected to the pressure relief valve 303, and the pressure relief valve 303, the fixing pipe 306, and the storage tank 304 are connected to each other. A connecting pipe 305 is provided between the tanks 304, and the storage tank 304 is connected to the connecting pipe 305. The fixed pipe 306 is also provided with a flow restrictor 4 for controlling the flow direction of the medium. Specifically, during the process of the telescopic rod 102 controlling the upper mold 104 and the lower mold 105 to clamp the outer shell, the lower mold 105 will apply a thrust to the sliding column 302. When the sliding column 302 is subjected to upward pressure, the sliding column 302 pushes the hydraulic oil in the support column 301 to squeeze the pressure relief valve 303. If the pressure exceeds the preset value, the hydraulic oil flows into the storage tank through the connecting pipe 305. When the pressure in tank 304 decreases, the second spring 403 pushes the baffle 401 to reset, and the hydraulic oil in tank 304 flows back to support column 301 through fixed pipe 306, achieving dynamic pressure balance. There are no restrictions on the shape of tank 304; it can be square or cylindrical. During use, tank 304 can temporarily store the medium discharged from support column 301. The pressure relief valve 303 can adjust the pressure threshold of the medium inside support column 301 during use, thereby allowing for adjustments to the upper mold 104 and lower mold 104 as needed. The contact pressure between 05 is controlled. During use, the sliding column 302, together with the support column 301, provides a fixed support force to the lower mold 105. When the pressure applied by the upper mold 104 to the lower mold 105 is greater than the support force of the sliding column 302, the sliding column 302 will offset the excess pressure by discharging the medium inside the support column 301. The medium inside the support column 301 can be water or hydraulic oil. The sliding column 302 and the lower mold 105 can be connected by bolts or pins, which facilitates the replacement of the lower mold 105 during use.
[0031] like Figures 1 to 6As shown, the flow restrictor 4 includes a fixing frame 402, which is disposed inside the fixing tube 306. A connecting rod 404 is slidably connected inside the fixing frame 402, and the sliding direction of the connecting rod 404 is parallel to the axis of the fixing tube 306. A second spring 403 is sleeved on the outside of the connecting rod 404, and the two ends of the second spring 403 are respectively connected to the connecting rod 404 and the fixing frame 402. A baffle 401 is provided at one end of the connecting rod 404. Specifically, after the outer side is processed, the telescopic rod 102 controls the upper mold 104. After separating from the lower mold 105, the first spring 202 provides a reverse thrust to the lower mold 105, which pulls the sliding column 302 during the reverse movement of the lower mold 105. This causes the medium inside the storage tank 304 to be added to the support column 301 through the connecting pipe 305 and the fixed pipe 306, thereby restoring the stroke of the sliding column 302. The direction of the medium flowing inside the fixed pipe 306 is controlled by the cooperation of the second spring 403 and the baffle 401, ensuring the stability of the sliding column 302 during use.
[0032] like Figures 1 to 6 As shown, a groove 203 is also provided on the outer side of the connecting block 201. Specifically, during use, the sliding column 302 guides the pipeline connected to the lower mold 105 to avoid interference between the external pipeline and the connecting block 201 during the movement of the lower mold 105.
[0033] like Figures 1 to 6 As shown, the sliding column 302 is also provided with a sealing ring relative to the inner wall of the support column 301, and the sealing ring slides inside the support column 301. Specifically, the sealing ring seals the gap between the sliding column 302 and the support column 301, ensuring that the sliding column 302 can stably support the lower mold 105 during use.
[0034] like Figures 1 to 6 As shown, the working state of this notebook shell hot pressing molding device is as follows: when the upper mold 104 and the lower mold 105 are needed to process the shell, the upper mold 104 and the lower mold 105 are first pressurized on the shell by the telescopic rod 102. When the pressure applied by the upper mold 104 to the lower mold 105 is greater than the preset value of the pressure relief valve 303, the sliding column 302 releases the excess pressure by discharging the medium inside the support column 301, so as to avoid the shell being damaged due to excessive pressure during use.
[0035] In summary, this utility model includes: a workbench 1, on the top of which a guide frame 103, a sliding plate 101, and a telescopic rod 102 are sequentially arranged, with the sliding plate 101 sliding outside the guide frame 103. An upper mold 104 is provided on the side of the sliding plate 101 facing the workbench 1, and a lower mold 105 is correspondingly provided on the workbench 1, with the upper mold 104 connected to the sliding plate 101; and a support mechanism, disposed on the outside of the workbench 1, for providing support for the outer shell. The support mechanism includes a guide member 2 and a buffer member 3. The guide member 2 is disposed on the outside of the workbench 1 for guiding the movement direction of the lower mold 105, and the buffer member 3 is disposed inside the guide member 2 for supporting the lower mold 105. The guide 2, in conjunction with the buffer 3, controls the pressure between the upper mold 104 and the lower mold 105. This invention, through the arrangement of the guide 2, buffer 3, and flow restrictor 4, achieves control over the extrusion pressure between the upper mold 104 and the lower mold 105 during use. This is achieved through the cooperation of the connecting block 201, the first spring 202, the support column 301, the sliding column 302, the pressure relief valve 303, the storage tank 304, the connecting pipe 305, the baffle 401, the fixing frame 402, and the second spring 403. This prevents excessive extrusion pressure between the upper mold 104 and the lower mold 105, which could lead to localized deformation and surface scratches on the metal casing, thus ensuring product yield and appearance quality.
