Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0028] In the embodiments of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0029] In one embodiment of the present utility model, as Figures 1 to 6 shown, a mold for a tablet computer shaft housing is provided, including an upper mold 10, a mold core 20, a jacking mechanism 30, a cooling mechanism 40, and a lower mold 50; the mold core 20 includes an upper mold core 21 and a lower mold core 22, and at least two mold positions 23 for forming the shaft housing 1 are provided on the mold core 20; the upper mold core 21 is arranged at the bottom of the upper mold 10; the lower mold core 22 is arranged at the top of the lower mold 50; the jacking mechanism 30 is arranged at the bottom of the lower mold core 22, and one end of the jacking mechanism 30 extends into the lower mold core 22. When the lower mold 50 moves away from the upper mold 10, the jacking mechanism 30 ejects the formed shaft housing 1; the cooling mechanism 40 includes a first cooling pipe 41 and a second cooling pipe 42; the first cooling pipe 41 penetrates through the upper mold core 21 and the upper mold 10, the second cooling pipe 42 penetrates through the lower mold core 22 and the lower mold 50, and a cooling medium is provided in the first cooling pipe 41 and the second cooling pipe 42. The cooling medium is a liquid or a gas.

[0030] The mold core 20 is provided with at least two mold positions 23 for molding the shaft housing 1, which can effectively improve production efficiency, realize the production of multiple products with one mold, and reasonably optimize the mold structure and layout; an efficient cooling channel is designed, and a cooling medium is introduced into the pipe through the first cooling pipe 41 and the second cooling pipe 42 to accelerate the cooling rate of the plastic part, improve production efficiency, and ensure the molding quality of the plastic part.

[0031] Furthermore, the cooling mechanism 40 can adopt the following methods: Water cooling: This is the most common cooling method, which uses the high specific heat capacity and good thermal conductivity of water to absorb the heat of the mold. The circulating water removes the heat through the first cooling pipe 41 and the second cooling pipe 42. Oil cooling: Oil with good thermal conductivity is used as the cooling medium, and the oil is absorbed and removed by flowing through the first cooling pipe 41 and the second cooling pipe 42. Gas cooling: An inert gas such as nitrogen is used, and cooling is achieved by flowing the gas through the first cooling pipe 41 and the second cooling pipe 42.

[0032] In addition to installing pipes within the mold, other methods include: Air cooling: Using a fan or air compressor to blow cool air across the mold surface for cooling. This method is less expensive, but the cooling rate is relatively slow. Spacer cooling: Using spacers made of copper or other thermally conductive materials within the mold, water flows through the spacers for cooling. Jet cooling: Using a nozzle to spray the cooling medium directly onto the mold surface for rapid cooling.

[0033] Furthermore, the lower mold 50 includes a lower mold plate 51 , and the lower mold core 22 is disposed on the lower mold plate 51 . The lower mold plate 51 can drive the lower mold core 22 to move in the vertical direction.

[0034] In this example, the first cooling pipe 41 and the second cooling pipe 42 are both spiral pipes. Specifically, a spiral water channel is designed inside the mold to achieve uniform cooling through the flow of water.

[0035] In this example, a guiding mechanism 60 is further included. The guiding mechanism 60 is disposed at opposite ends of the mold core 20 and includes an inclined rod 61 and a slider 62. The inclined rod 61 is disposed on the upper mold 10 and penetrates through the upper mold core 21 obliquely. The slider 62 is slidably disposed on the lower mold 50, and an inclined hole 621 adapted to the inclined rod 61 is provided on the slider 62. The two inclined rods 61 are arranged in a V shape. Specifically, during the process that the lower template 51 is pushed by the mold closing system to move towards the upper mold 10, the inclined hole 621 on the slider 62 will contact the inclined rod 61 first. Since both the inclined hole 621 and the inclined rod 61 are inclined and the inclined rod 61 is inserted into the inclined hole 621, during the process that the lower template 51 moves towards the upper mold 10, the two sliders 62 will approach each other under the action of the inclined rod 61.

[0036] In this example, the guiding mechanism 60 further includes a top block 63. The top block 63 is connected to the top of the upper mold 10 and is located beside the upper mold core 21 for guiding and positioning the slider 62. Specifically, the mold design is optimized to reduce the need for manual demolding, improve the automation level, and avoid deformation or cracking of the plastic part. Effective demolding structures such as the slider 62, the top block 63, and the lifting mechanism 30 are adopted to ensure a smooth demolding process and the integrity of the plastic part.

[0037] In this example, a first inclined surface 631 is provided on one side of the top block 63 facing the upper mold core 21. A second inclined surface 622 is provided on one side of the slider 62 facing away from the lower mold core 22, and the slope of the second inclined surface 622 is the same as that of the first inclined surface 631. Specifically, the first inclined surface 631 and the second inclined surface 622 can make the slider 62 fit better with the top block 63 and make the slider 62 slide stably.

[0038] In this example, a shock absorption mechanism is further included. The shock absorption mechanism is disposed on the upper mold 10 or the lower mold 50 for absorbing impact force and vibration. Specifically, the shock absorption mechanism can adopt the following methods:

[0039] Set shock-absorbing pads: As described, the shock-absorbing pads are set at the bottom of the lower die 50, or shock-absorbing pads are placed between the die and the machine, which can absorb impact force and vibration and reduce damage to the die and the machine. Set shock absorbers: Use professional shock absorber equipment, such as hydraulic shock absorbers or pneumatic shock absorbers, which can effectively absorb and isolate vibration. Adopt soft connections: Use flexible connectors, such as rubber hoses or elastic couplings, between the die and the machine to reduce vibration transmission. Adopt damping materials: Use damping materials, such as rubber, foam or other special synthetic materials, at key parts of the die to absorb vibration. Adopt shock-absorbing bolts: Use specially designed shock-absorbing bolts, which are used to connect the components inside the die. The shock-absorbing bolts have the characteristics of shock absorption and energy absorption. Set shock-absorbing brackets: Add shock-absorbing brackets to the support structure of the die. These brackets can be made of metal or special materials to absorb and disperse vibration. Dynamic balance: Ensure the dynamic balance of the die and the machine to reduce vibration caused by imbalance. Set sound insulation covers: Set sound insulation covers around the die. Although mainly used to reduce noise, it also helps to reduce the spread of vibration. Optimize the design: Reduce the generation of vibration by optimizing the die design, such as reasonably distributing the weight and enhancing the structural rigidity. Set shock-absorbing feet: Install shock-absorbing feet at the bottom of the die or the machine, which can absorb and isolate the vibration transmitted from the ground.

[0040] In this embodiment, the jacking mechanism 30 includes a bottom plate 31 and a plurality of ejector pins 32. Each of the ejector pins 32 is arranged on the bottom plate 31, and the end of each ejector pin 32 passes through the lower die 50 and the lower die insert 22; the bottom plate 31 is arranged on the lower die 50. Specifically, the realization of demoulding by the ejector pins 32 is prior art and will not be described again.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
