BMC material is a thermosetting material that is mixed with various inert filling materials, multi-fiber reinforcement materials, catalysts, stabilizers and pigments to form a composite material for compression molding. Most of the existing BMC materials are injection molded by pressurization during injection molding.

[0003] Meanwhile, after the injection molding of the injection molded product in the prior art is completed, the injection molded product is usually taken out from the mold cavity by a direct ejection method. Although the injection molded product in the mold cavity can be ejected, there are defects in actual use because the ejection speed of the ejector rod is fixed and cannot be well controlled, which can easily cause damage to the injection molded product, so improvement is needed.

[0011] In a preferred embodiment, the ejector rod is movably inserted into the interior of the lower template and extends into the mold notch inside the lower template.

[0012] In a preferred embodiment, the rotating rod is installed inside a set of fixed plates through bearings, and the rotating rod is located below the top rod panel.

[0013] In a preferred embodiment, the driving members fixed on the rotating rod are equidistantly distributed, and two sides of the driving members are semicircular structures.
