く且つ熱ロスもないという利点がある。(Effects of the present invention) In the hot water supply method of the present invention, the hot water is supplied when the molten metal supplied into the injection sleeve is injected into the cavity at the point when the plunger tip blocks the hot water supply port to the injection sleeve of the runner pipe. The process is controlled so that the hot water supply pressure chamber returns to its pre-pressurized state and the hot water level in the hot water supply pressurized chamber matches the arbitrary position of the rising part of the runner pipe, so it is possible to prevent molten metal from leaking. Because there is no such place, there is no possibility of high-temperature molten metal spilling around and contaminating or damaging peripheral equipment, and since the molten metal is directly supplied to the injection sleeve through the runner pipe, It has the advantage that there is no entrainment of air and no heat loss unlike the conventional example.
