Description

Technical Field

[0001] This utility model relates to the field of mold cooling technology, and in particular to a keyboard molding mold cooling device. Background Technology

[0002] The keyboard casing, serving as the basic frame, is typically made of plastic or aluminum alloy. It protects the internal components and secures the keys. Aluminum alloy keyboard casings are usually formed using a hot stamping process. Stamping can efficiently process complex shapes while ensuring dimensional accuracy. Hot stamping of aluminum alloy casings requires heating the material above its recrystallization temperature to reduce deformation resistance and increase plasticity. The mold then rapidly stamps the material at high temperatures, causing it to fit into the mold cavity and form a high-precision structure.

[0003] However, the following defects still exist: after the existing stamping device completes the hot stamping of the keyboard shell, it is usually allowed to cool naturally without a cooling device for the mold. As a result, the cooling rate is slow and the mold shape is not very stable, which affects the work efficiency and the effect of use. In order to better address the above problems, promote the development of the industry's technical level, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0022] Reference Figures 1-4 A keyboard molding mold cooling device includes a housing 1. A lower mold 10 is fixed to the bottom inner wall of the housing 1 by bolts. A hydraulic cylinder 6 is fixed to the top outer wall of the housing 1 by bolts. One end of the telescopic part of the hydraulic cylinder 6 passes through the housing 1 and is fixed to an upper mold 7 that is adapted to the lower mold 10 by bolts. The heated aluminum alloy keyboard shell is placed into the lower mold 10, and then the upper mold 7 is pushed downward by the hydraulic cylinder 6 so that the upper mold 7 and the lower mold 10 cooperate to stamp and form the keyboard shell.

[0023] In this utility model, cavities are provided in both the lower mold 10 and the upper mold 7. A square storage box 9 is fixed to the bottom outer wall of the shell 1 by bolts. The storage box 9 is used to store coolant, which can be an aqueous solution of ethylene glycol. A semiconductor cooling chip is embedded in the storage box 9. The heat-absorbing end of the semiconductor cooling chip is located inside the storage box 9, which can absorb heat from the coolant. The heat-dissipating end of the semiconductor cooling chip is located outside the storage box 9.

[0024] Water pumps 3 are fixed to both outer walls of the housing 1 by bolts. Connecting pipes 4 are installed at both ends of the water pumps 3 by flanges. The lower connecting pipe 4 is connected to the storage tank 9, and the upper connecting pipe 4 passes through the housing 1 and is connected to the cavity of the lower mold 10. A hose 2 is glued to the top of the upper connecting pipe 4, and the hose 2 passes through the housing 1 and is connected to the cavity of the upper mold 7.

[0025] After stamping, one of the water pumps 3 draws coolant from the storage tank 9 through the connecting pipe 4, and the coolant enters the cavity of the upper mold 7 and the lower mold 10 through the connecting pipe 4 and the hose 2. At the same time, the other water pump 3 draws coolant from the cavity of the upper mold 7 and the lower mold 10 through the connecting pipe 4 and the hose 2, and the coolant flows into the storage tank 9 through the connecting pipe 4. This cycle is repeated, so that the coolant flows from the cavity of the upper mold 7 and the lower mold 10, thereby absorbing the heat of the keyboard shell and cooling the keyboard shell. This allows for rapid cooling and forming of the stamped keyboard shell, saving time and improving work efficiency.

[0026] In this utility model, the bottom outer wall of the housing 1 is provided with an ejection assembly for ejecting the formed keyboard shell. The ejection assembly includes a rotating shaft 13. Two connecting plates are welded to the bottom outer wall of the housing 1. The rotating shaft 13 is rotatably connected between the two connecting plates through a bearing. A knob is provided at one end of the rotating shaft 13. Two gears 15 are connected to the outer key of the rotating shaft 13.

[0027] The bottom of the lower mold 10 has two through slots 11, and each of the two through slots 11 is provided with a top block 12. A top rod 14 is welded to the bottom of the top block 12. The bottom end of the top rod 14 passes through the housing 1 and is welded with a rack 22. The top of the top block 12 is flush with the upper surface of the bottom of the lower mold 10. The rack 22 can mesh with the gear 15.

[0028] Once the keyboard shell is formed, turn the knob, and the rotating shaft 13 will drive the gear 15 to rotate. The gear 15 will drive the rack 22 to move upward, and the rack 22 will drive the push rod 14 to move upward. The push rod 14 will push the push block 12 to move upward, so that the push block 12 will push the keyboard shell formed in the lower mold 10 out of the lower mold 10, thereby making it easier to remove the formed keyboard shell and improving convenience.

[0029] In this utility model, a frame 21 is welded to the bottom of the shell 1, and a T-shaped groove 18 is provided on one side of the frame 21. A T-shaped slider 19 is slidably connected in the T-shaped groove 18. A connecting rod 20 is welded to the bottom end of the two racks 22, and the connecting rod 20 is fixed to the T-shaped slider 19. The top block 12 can be supported by the cooperation of the T-shaped slider 19 and the connecting rod 20. At the same time, the cooperation of the T-shaped slider 19 and the T-shaped groove 18 will guide the movement of the racks 22, thereby ensuring that the top block 12 can move vertically up and down.

[0030] In this utility model, two through holes are opened at the bottom of the shell 1, and a placement frame 17 is welded inside the storage box 9 at the position directly below the two through holes. Two electric fans 8 are fixed inside the placement frame 17 by bolts.

[0031] During the cooling process of the keyboard casing, the electric fan 8 is turned on. The electric fan 8 blows air through the through hole to the lower mold 10, thereby assisting in cooling the keyboard casing inside the lower mold 10 and improving the cooling efficiency of the keyboard casing.

[0032] A door panel is hinged to one side of the housing 1, and a viewing window 5 is provided on one side of the door panel. A latch for fixing the door panel is fixed to one side of the housing 1 by bolts.

[0033] Working principle: When needed, the heated aluminum alloy keyboard shell is placed into the lower mold 10, and then the upper mold 7 is pushed downward by the hydraulic cylinder 6, so that the upper mold 7 and the lower mold 10 cooperate to stamp the keyboard shell.

[0034] After stamping, one of the water pumps 3 draws coolant from the storage tank 9 through the connecting pipe 4, and the coolant enters the cavity of the upper mold 7 and the lower mold 10 through the connecting pipe 4 and the hose 2. At the same time, the other water pump 3 draws coolant from the cavity of the upper mold 7 and the lower mold 10 through the connecting pipe 4 and the hose 2, and the coolant flows into the storage tank 9 through the connecting pipe 4. This cycle is repeated, so that the coolant flows from the cavity of the upper mold 7 and the lower mold 10, thereby absorbing the heat of the keyboard shell and cooling the keyboard shell. This allows for rapid cooling and forming of the stamped keyboard shell, saving time and improving work efficiency.

[0035] At the same time, the electric fan 8 is turned on, and the electric fan 8 blows air through the through hole to the lower mold 10, thereby assisting in cooling the keyboard shell inside the lower mold 10 and improving the cooling efficiency of the keyboard shell.

[0036] Once the keyboard casing is formed, turn the knob. The rotating shaft 13 drives the gear 15 to rotate. The gear 15 drives the rack 22 to move upward along the T-shaped slide groove 18 through the connecting rod 20 and the T-shaped slider 19. The rack 22 will drive the push rod 14 to move upward. The push rod 14 will push the push block 12 to move upward, so that the push block 12 pushes the keyboard casing formed in the lower mold 10 out of the lower mold 10, thereby making it easier to remove the formed keyboard casing and improving convenience.

[0037] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
