Abstract

PURPOSE: To prevent the breakdown of the captioned cylinder by covering part or the whole of the outside circumference of the captioned cylinder of a hot-chamber type die casting machine by the molding of material of a Young's modulus lower than that of the cylinder thereby absorbing and relieving the compressive force acting upon solidification of molten metal.
CONSTITUTION: In case the molten metal pressure cylinder 1 is of, e.g., boride or nitride base, the outside circumference thereof is covered with molding 10 of material which is of 1000kg/mm2 or less in Young's modulus and is not attacked by molten aluminum alloy 9, e.g., graphite. It is then mounted to the injection pump body 7 of the die casting machine by way of a gasket packing 8. In this way, the compressive force generated at the boundary surfaces owing to solidification of the molten aluminum alloy 9 in long-time dwell is made extremely small.
