Abstract
The present invention relates to an improvement of an injection apparatus in a die casting machine of a horizontal injection type in which molten metal is poured into an injection sleeve mounted and held in a horizontal state with a fore end opening connected to an inlet of a die, and the poured molten metal is injected into the die by a piston motion of a plunger of an injection cylinder. A storage vessel capable of being sealed hermetically is attached to a pouring port formed in the injection sleeve and molten metal in a heat retaining furnace is supplied to the storage vessel periodically through a feed pipe, whereby the pouring into the injection sleeve is quickened to thereby increase the number of shots per hour despite the die casting machine having the injection apparatus of a horizontal injection type.
