Abstract

PURPOSE: To inject molten metal surely at a uniform acceleration by charging the molten metal into an injection sleeve then changing the advance speed of a plunger rod continuously from zero to an arbitrary speed at a uniform acceleration.
CONSTITUTION: When molten metal 4 is teemed from a ladle 6 into an injection sleeve 1 and a plunger rod 3 is operated continuously from zero speed successively up to an arbitrary speed at a uniform acceleration, a leading end tip 2 presses the molten metal 4 successively to a sprue 5. At this time, air and the like discharged as shown by an arrow, and the molten metal 4 free from the inclusion of air is injected through the spure 5. According to this method, a good die cast product contg. no air is obtained in a short injection time.
