The ejection sleeve lubricating device and ejection sleeve lubricating mannered null abbreviation of the horizontal ejection

摘要

PROBLEM TO BE SOLVED: To provide a device and method for lubricating an injection sleeve of a diecasting machine, such that, while use of a lubricant is suppressed, galling is prevented from being generated and that shortening of the life of the injection sleeve or a plunger tip and deterioration of die-casting workability are suppressed.;SOLUTION: The injection sleeve lubricating device 15 is equipped with an injection sleeve 17 in which molten metal is poured from a pouring port 17a, a plunger tip 19 which force-feeds the molten metal in the injection sleeve 17 to a cavity 16, a lubricant jetting device 21 which jets a lubricant to the inner face of the injection sleeve 17, and a sucking device 22 which evacuates inside the injection sleeve 17. By operating the sucking device 22 of this injection sleeve lubricating device 15, the injection sleeve 17 is evacuated inside from a clearance between the inner peripheral face 17b of the injection sleeve 17 and the outer peripheral face of the plunger tip 19 by way of a suction passage 24, thereby drawing the lubricant together with air.;COPYRIGHT: (C)2005,JPO&NCIPI
