Abstract
Improvements in injection devices for cold chamber, metal and non-ferrous alloy press molding machines, which causes an extremely effective spill effect on the liquid metal, characterized in that each device is provided with an injection piston, which receives the compressive stress of the casting machine but does not come into contact with the metal, sliding freely and coaxially inside a pressure piston that transmits the compression force to the metal to be molded located in a container, thus forming a chamber in which a gas, inert with respect to the metal to be molded, previously introduced under an initial pressure of 50 to 500 bar and preferably 100 to 150 bar, is, thanks to a coaxial sealing needle, trapped and compressed between the pressure piston and the injection piston, and then, towards the end of the injection of the metal into the mold, it remains tightly compressed between the pressing piston, immobilized by the metal that begins to solidify on the walls of the container and the injection piston that continues to advance, and then, by the advance of the sealing needle pushed by the injection piston at the end of the race, is released and distended in the container where it causes the effect of sprue.
