ABSTRACT:
This invention relates to improvements on an injection device in a hot chamber type die casting machine in which molten metal reserved in a heat retaining furnace or the like is injected into a mold according to a hot pressurizing chamber system. A goose neck formed of ceramics is provided in a heat retaining pot formed of ceramics for reserving molten metal such that the bottom of the goose neck is attached fixedly to the inside surface of bottom of the heat retaining pot, and by additionally providing a heat retaining material incorporating a heating wire and formed of ceramics on the outer surface of bottom and the outer peripheral surface of the heat retaining pot is firmly fixed the goose neck in the heat retaining pot while shock load forces applied to the bottom of the goose neck are transmitted to the bottom of heat retaining pot and absorbed and reduced by the bottom and further the heat retaining pot is effectively reinforced by the heat retaining material.
