METHOD OF AND SYSTEM FOR OPERATING SQUEEZE PLUNGER IN DIE CAST MACHINE |
摘要 |
A method of and a system for operating a squeeze plunger in a die cast machine. When the fill-up of molten metal in a cavity is completed by an injection plunger, the moving speed of the injection plunger is rapidly decreased. When the speed at this time becomes lower than a preset value, a preset delay time is measured. After a lapse of this delay time, the squeeze plunger is operated to press a molding material in the cavity, so that plastic flows are caused in the molding material.
