[0003] Currently, some computer housing production still relies on split assembly process, which first processes each part of the housing and then assembles them. This method not only forms obvious joints at the joint, resulting in insufficient structural strength and easy cracking of the housing, but also causes low size accuracy and poor appearance flatness due to errors in manual alignment and assembly, which seriously affects product quality and service life. Even if injection molding process is used, the existing equipment has key defects: lack of stable mold moving and positioning structure, the lower mold movement relies on manual pushing, and the upper mold lifting has no reliable limiting guide, resulting in low mold closing precision and easy molding defects. At the same time, the equipment has low automation, and manual intervention is required from mold alignment, injection molding to finished product removal, resulting in complicated production process, long time consumption, and single cooling system design, which can only cool one side or part of the mold, slow the solidification speed of plastic raw materials, further prolong the production cycle, and make the equipment utilization rate low and the production efficiency difficult to improve, which cannot meet the mass production demand. In summary, the core technical problems that need to be solved in the current computer housing production field are: traditional processes or equipment cannot balance the integrated high-precision molding, automated efficient production and rapid cooling of computer housings, resulting in poor product quality, low production efficiency, long production cycle, and difficulty in adapting to mass production demand.
