Abstract
PURPOSE: To prevent the erosion and damage of cylinder by molten metal by forming the inner cylinder and outer ring of the captioned injection pump for Al-base- and Zn-base-alloys by ceramics of two kinds in characteristics.
CONSTITUTION: The inner cylinder 20 of the injection pump of the hot chamber type die casting machine which diecasts molten metal of Al-base- and Zn-base alloys is provided to the sliding portion of a plunger tip 15. Hence, the cylinder 20 is formed by the composite ceramics or the like of high abrasion resistance, corrosion resistance and high-temperature strength composed of titanium diboride and boron carbide as well as boron nitride. The outer ring 21 on the outside circumference therof is formed by the sialon base ceramics or the like composed primarily of silicon nitride and alumina of high corrosion resistance, thermal impact resistance and high-temperature strength. These which are separately formed are mechanically fitted or the ring 21 is so formed as to enclose the cylinder 20 through atmospheric sintering process or the like.
