[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, a wide variety of colors and patterns, shapes from simple to complex, sizes from large to small, and precise product dimensions. The product is easy to update and can be made into parts with complex shapes. Injection molding is suitable for mass production and molding processing fields such as products with complex shapes. By laser processing the inner cavity of the injection mold to form a brushed texture, the surface of the injection molded panel can be formed with a brushed texture.

[0003] When the injection mold is in use, the liquid flows into the cavity during injection, causing part of the molten plastic to solidify during the injection process, which in turn affects the quality of the injection molding.

[0042] When the upper mold 210 is fitted with the lower mold 230 under the drive of the lifting component 100, injection molding begins, and the liquid enters the groove of the lower mold 230 through the first feed pipe 500 and the second feed pipe 600. The heating component 800 sleeved on the outer wall of the second feed pipe 600 heats the liquid. At the same time, a heating pipe is provided in the upper mold 210 to heat the upper mold 210 during injection molding. When the injection molding is completed, the heating pipe stops heating, and the coolant enters the coolant groove 260 on the lower mold 230 through the coolant inlet 270, and then flows out through the coolant outlet 280 to cool the mold.

The liquid enters the second rotating tube 453 through the first feeding pipe 500 to drive the inner fan blade 455 to rotate. The air with odor during the injection molding process is sucked into the filter box 420 through the second suction pipe 451 for purification, and the purified air is discharged through the exhaust fan 440. After the injection molding is completed, when the mold is opened, the upper mold 210 moves upward under the drive of the lifting component 100, drives the threaded rod 220 to rotate, and drives the shaftless fan 412 to rotate through the linkage mechanism 300, so that the air with odor when the mold is opened is sucked into the first suction pipe 414, and then enters the filter box 420, and then is filtered through the filter element 430 set in the filter box 420, and finally The purified air is discharged through the exhaust fan 440, and the upper mold 210 moves away from the lower mold 230 while driving the top block 240 to eject the molded panel from the lower mold 230, making it easier to demold the molded air-conditioning panel.
