EJECTOR MECHANISM OF MOLDED PRODUCT IN INJECTION MOLD

摘要

PURPOSE:To discharge a molded product outside of a mold even if an ejector pin is driven deeply in the molded product is in existence, by constituting the title mechanism so that a difference is given between a stroke of the first ejector pin and a stroke of the second ejector pin. CONSTITUTION:An ejector 12 of a molding machine is actuated in the direction of an arrow A and pushes an ejector plate 7. At the same time, an ejector plate 6 is pressed through a spring 10 and washer 13 and ejector pins 2, 3 being to move simultaneously. Then at a point of time when the ejector plate 6 collides with a cavity plate 4, the ejector pin 2 is suspended. Then only the ejector plate 7 and ejector pin 3 are moved away while bending a spring 10, suspended at a point of time when the ejector plate 6 is stuck close to the ejector plate 7 and an ejection action is completed. With this movement, the molded product 1 is ejected through a cavity plate 4 by the pins 2, 3 to begin with, then after suspension of the pin 2, bite part between the pin 2 and the molded product 1 is removed by the pin 3.
