FORMING DIE ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide a forming die assembly capable of smoothly extracting the resin of a submarine gate part. SOLUTION: The forming die assembly has a submarine gate 15 piercing through the movable die 12 from the leading end of a runner 14 to communicate with a cavity 13. An extrusion member 23 for extruding the runner 14 is provided to the movable die 12 so as to advance and retreat in a die on-off direction to extrude the resin R at the part of the runner 14 between the submarine gate 15 and a runner locking part 16. The resin R in the runner 14 is bent by extruding the resin R in the runner 14 by the extrusion member 23 to smoothly extract the resin R in the runner 14 from the submarine gate 15.
