Abstract

PURPOSE: To attempt to make uniform the pressure distribution in the cavity at the time of injection to obtain a short tube of uniform thickness by providing a through hole in the slide core of the forming metal die of a short tube having bent portions.
CONSTITUTION: A through hole 10 is formed in a direction intersecting rectangularly to the axial direction, that is, in the direction the same as the injection direction from the gate 7 of a molten material, is formed at the core part 5a of a first slide core 5. A projecting cylinder device 11 is fitted in a movable core 3 so that a projecting rod 11a is aligned coaxially with the through hole 10 of a first slide core 5 at the time of the die opening operation, and shrinked and driven at the time of completion of the die opening operation. A part of the molten material injected into the cavity 9 from the spool gate 7 is injected directly through the through hole 10 to the rear side part of the spool gate 7 and the filling of the molten material is performed from two directions.
