Abstract
PURPOSE: To obtain the captioned gate structure capable of releasing a molded part reliably from a metallic mold by a method wherein a dead gate is arranged under a specific state in a sliding hole opened to a runner and between the point of an ejector pin for projecting the runner and the runner.
CONSTITUTION: The ejector pin 8 for projecting the runner is arranged slidably in a sliding hole 6 opened to the runner 3 in the metallic mold A so that the position of the point of the ejector pin 8 is placed on a height nearly equal to the height of the opening part 7 to a cavity 4 of a tunnel gate 5. Plastic is filled in the dead gate 9 also and when the molded part and the runner part are cut at the open end of the tunnel gate 5 and projected from the metallic mold, they are projected in a unitary body and reliable mold-releasing operation can be made.
