MOLTEN METAL INJECTION DEVICE FOR CENTRIFUGAL CASTING AND CENTRIFUGAL CASTING MACHINE USING SAME

摘要

The present invention relates to a molten metal injection device for centrifugal casting, and a centrifugal casting machine using the same. The molten metal injection device for centrifugal casting injects molten metal into a mold space formed between an upper mold and a lower mold rotating and engaging each other to cast. The molten metal injection device comprises: an injection unit having an inlet on one end inserted into a shrink head formed on a rotational axis of the upper mold, injecting the molten metal into the inlet, and having one end separated from the shrink head as the molten metal is injected; a stopper inserted into the injection unit through the other end thereof to control a flow of the flowing molten metal to open and close the inlet; and a base unit having the injection unit and lifting the same. The molten metal injection device lifts the injection unit controlling whether to inject molten metal or not and an amount of injection to minimize turbulence during injection of molten metal.;COPYRIGHT KIPO 2017
