In the implementation process of this embodiment, the multi-cavity mold assembly 100 (upper mold and lower mold) is assembled on the main machine bed, and the thickness adjustment of each cavity is controlled by a hydraulic device.

Through independent hydraulic control, the thickness and shape of each cavity can be adjusted separately, ensuring the molding requirements of different areas and meeting the complex structural design requirements of the shell.

[0027] In some embodiments, the layered injection molding unit 200 includes a plurality of injection nozzles, and the nozzles are arranged along the top of the cavity of the mold assembly 100.

[0028] In some embodiments, the nozzle is connected to the support frame of the layered injection molding unit 200, the support frame is fixed above the mold assembly 100, and the nozzle spacing is arranged according to the spacing of the cavity. The support frame is fixed above the mold, and each nozzle is installed on the support frame.

The support frame fixes the nozzle position, ensures the accuracy of multi-layer injection molding, improves the stability of the molding structure, and makes the material performance of the inner and outer layers of the shell meet the design requirements.

[0029] In some embodiments, the variable frequency cooling system 300 includes a cooling compressor and a cooling pipe. The cooling pipe is arranged along different areas of the mold assembly 100, and each cooling pipe is provided with a cooling outlet. The spacing of the cooling outlets is determined according to the cavity distribution of the mold assembly 100. After such arrangement, the cooling pipes of the variable frequency cooling system 300 are distributed in different areas of the mold assembly 100, and the flow rate and temperature are adjusted by the variable frequency of the cooling compressor to ensure that the shell is evenly cooled during the molding process. The cooling pipes are arranged around the mold assembly 100, and the pipe spacing is designed according to the mold cavity distribution, and cooling outlets are provided on the pipes, and the cooling compressor is connected to the pipes. The control system 500 adjusts the cooling speed and distribution of the cooling pipes through the variable frequency controller to ensure uniform temperature in the cavity. In this way, the variable frequency cooling system 300 realizes precise control of cooling, avoids warping and deformation during the molding process, and enables the molded parts to have better dimensional accuracy and surface flatness.

[0030] In some embodiments, the outside of the cooling pipe is coated with a high-efficiency heat dissipation material, and the cooling pipe is distributed in the heat concentration area of ​​the mold assembly 100. The frequency conversion controller is connected to the cooling compressor to adjust the cooling flow rate. The frequency conversion controller adjusts the cooling flow rate through temperature data, and the cooling system 300 performs centralized cooling in the high-temperature area to effectively reduce the temperature difference. The cooling pipe is coated with a high-efficiency heat dissipation material on the outer layer to enhance the cooling effect.

In this way, the intelligent temperature control system 400 relies on multi-point temperature sensors to monitor the mold temperature in real time, adjust the temperature according to the different positions of the mold cavity and the cooling pipe, and ensure that the temperature in each area is balanced. The temperature sensors of the temperature control system 400 are distributed at different positions around the mold cavity to achieve multi-point temperature monitoring. The sensor is connected to the temperature adjustment module, and the temperature in the cavity is dynamically adjusted by real-time monitoring of the temperature data. In this way, multi-point temperature control effectively avoids structural warping or material stress concentration caused by temperature difference, and improves the molding accuracy and consistency of the product.

[0032] In some embodiments, the control system 500 includes a central controller and a regional control module, the central controller is connected to the injection unit, the cooling system 300 and the temperature control system 400, and the regional control module is connected to the nozzle, cooling pipe and temperature adjustment module of the layered injection unit 200 respectively. The central controller of the control system 500 automatically adjusts the injection pressure, cooling flow rate and temperature distribution through communication with the injection unit, the cooling system 300 and the temperature control system 400 to ensure the accuracy and consistency of the shell molding process. At the same time, the system uses recyclable environmentally friendly materials to minimize the impact on the environment. In other embodiments, the central controller of the control system 500 is connected to the layered injection unit 200, the cooling system 300 and the temperature control system 400 respectively through the regional control module. The regional control module independently controls the injection, cooling and temperature control parameters of each region to ensure that each region works independently and does not interfere with each other. The combined use of the central controller and the regional control module realizes the independent control of each region, improves the flexibility and accuracy of the production process, and ensures the high accuracy and consistency of the shell molding.

[0033] In some embodiments, the central controller monitors the injection, cooling and temperature parameters of each area in real time, and automatically adjusts the injection pressure, cooling speed and temperature settings according to the feedback data to maintain a stable environment in the cavity. The real-time monitoring and automatic adjustment function of the central controller significantly improves the stability of molding, avoids molding defects caused by temperature and pressure fluctuations, and improves the overall quality of the laptop computer shell.

[0034] In some embodiments, the temperature adjustment module is connected to the control system 500 through a temperature feedback control circuit. The temperature sensor feeds back the detection data to the control system 500, and the system adjusts the injection molding, cooling and temperature control parameters in real time to maintain the temperature stability. Through the feedback control mechanism, precise control of temperature adjustment is achieved, molding defects caused by temperature fluctuations are reduced, and the production quality and stability of the shell are improved.

[0035] This system is not only superior to traditional processing technology in terms of structural strength, reducing the strength degradation problem caused by interface gaps, but also achieves uniformity and visual consistency in heat dissipation through intelligent cooling and layered injection molding design, reducing production costs and improving product appearance quality.
