Abstract
PURPOSE: To ensure a smooth withdrawal of a molding with a first opening and a second opening by separating a second opening formation boss with a knock pin lifted after a first opening formation core is separated with a lower die lifted when the die is opened.
CONSTITUTION: After the completion of injection molding, an upper die 4 rises separating from a lower die 5, the lower die 5 moves up vertically with the action of a spring 10 in such a manner as to be blocked with a stopper 23. Meanwhile a molding 1 is lifted sticking on the lower die 5 and a core 11 projected on a base 6 is pulled out of the molding 1. After the separation of the core, with the thrust of a driving block 13, a knock pin 21 slides in a guide hole 8 thereof of the lower die 5 and is pushed out. A component force accompanied by the rise of the knock pin 21 works a mobile tapered block 18 to slide in a engaging groove 16 of the driving block 13. With the action of the knock pin 21, the modeling 1 is forced up along the axis of a boss 9 of the lower die 5 and separated.
