s4, the first baffle (2) and the second baffle (3) move to the position below the air cooler (24), so that the female die (6) and the male die (7) are located at the bottom of the connecting pipe (28) below the air cooler (24), the air cooler (24) is started to cool the female die (6) and the male die (7), when the temperature between the female die (6) and the male die (7) is reduced to 40 +/-5 ℃, the female die (6) is separated from the male die (7), and an injection molding workpiece is separated from the interior of an injection molding die cavity to obtain the injection molding workpiece;
and (5) sliding the injection molding workpiece in the steps S5 and S4 out of the discharge port (14) along the discharge groove (30), detecting the injection molding workpiece, and obtaining an injection molding finished product after the detection is qualified.
