MOLTEN COPPER POURING APPARATUS FOR COPPER DIECASTIN

摘要

PURPOSE: A molten metal injection device for copper diecasting is provided to prevent the loss of materials due to scattering by maintaining stable flow of molten copper through a runner. CONSTITUTION: A molten metal injection device for copper diecasting comprises an injection unit and a high-frequency oscillator. The injection unit is installed with one side facing a melting furnace(10) and the other side facing a diecasting sleeve, and the injection unit has a runner(201) through which molten copper discharged from a crucible flows and a heating coil(102) for maintaining the molten copper over the melting temperature at the wall part of the runner. The high-frequency oscillator supplies the heating coil of the injection unit with power for high-frequency induction heating.
