The idle lower mold 9 is moved to the lower side of the upper mold 4. The production is not required to wait for the lower mold 9 loaded with the injection molded part to be demolded before production, thereby improving the production efficiency.

[0021] In the embodiment, the motor 2 drives the rotating shaft 5 to rotate to drive the lower mold 9 to rotate. When the lower mold 9 is rotated to the lower side of the upper mold 4, the electric telescopic rod 3 drives the upper mold 4 to move downward, so that the upper mold 4 is combined with the lower mold 9. Then, the injection liquid is injected into the mold through the injection port. After the injection liquid is cooled and solidified, the electric telescopic rod 3 drives the upper mold 4 to move upward. Then, the motor 2 drives the rotating shaft 5 to rotate, so that the lower mold 9 is rotated to the bottom of the rotating shaft 5. Then, the moving mechanism drives the ejector rod 16 to move. The ejector rod 16 can thereby eject the plastic part, thereby achieving the effect of automatic demolding.
