[0027] During specific implementation, four workstations are set on the tray 202. First, the upper mold 5 and the lower mold 6 in the front are injection molded. The driving motor 204 drives the gears in the reducer 205 to rotate, reduce speed and increase torque, drive the active gear 206 to drive the driven gear 207, drive the support 201 to rotate, drive the tray 202 to rotate, and the pulley 203 supports the tray 202. The upper mold 5 and the lower mold 6 in the front are rotated to one side for cooling, and the other upper molds 5 and lower molds 6 are rotated to the front for injection molding. When the first group of upper molds 5 and lower molds 6 are rotated to the front again, they have been cooled and formed. The formed motor fan blades are taken out, and the cycle is continued. Four groups of molds are extended for compression molding, and the cooling time of the molds is staggered to improve production efficiency and compression molding is performed.

The other end of the liquid inlet pipe 901 is fixed in the liquid outlet box 902, and the upper surface of the upper mold 5 close to the liquid outlet box 902 is connected to the liquid outlet box 902. It is connected to an air pump 903, and an air suction pipe 904 is connected above the air pump 903.

[0030] In summary, when using the motor fan blade injection molding machine with an extendable die, first, if the construction period is urgent, the four sets of die-casting machines on the tray 202 are used for die casting in sequence, the hydraulic rod 4 is started to press the upper mold 5 on the lower mold 6 for mold closing, and the motor in the injection molding machine 7 drives the piston to inject the molten injection liquid from the injection tube 8 into the mold cavity of the upper mold 5 and the lower mold 6, and a certain pressure is applied, and the injection of the injection liquid is stopped, and then the vacuum pump 903 is used to evacuate air to break the bubbles in the injection liquid, so that the injection liquid fills the upper mold 5 and the lower mold. The mold cavity in the mold 6 is waited for cooling, and then the driving motor 204 drives the tray 202 to rotate, and the upper mold 5 and the lower mold 6 in the front are rotated to one side for cooling, and the other hydraulic rods 4 and the upper mold 5 are molded and pressed. When the first group of hydraulic rods 4 and the upper mold 5 are rotated to the front again, the models in the hydraulic rods 4 and the upper mold 5 have been cooled.
