METHOD FOR SETTING INJECTION VELOCITY OF CASTING IN DIE CASTING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a method for setting injection velocity of a casting in a die casting machine with which the danger enclosing the air in an injection sleeve into molten metal at the increasing velocity range of a plunger is not developed and the molten metal temperature can be kept to automatically set the injection velocity pattern.;SOLUTION: The first velocity pattern is made from the set normal velocity V1 and the upper limit value α1 of acceleration, and an approximate expression for this first injection velocity, is obtained and the injection velocity pattern is set based on the approximate expression. However, the maximum value α2 of the acceleration calculated from the approximate expression is α2α1.;COPYRIGHT: (C)2006,JPO&NCIPI
