なるスプルースラグ引抜き装置。A spruce lag pulling device for pulling out the spruce lug through the drawing rod, which is formed by molding a drawing rod connected to the sprue lug molded in the sprue of a special injection molding mold, and has a spruce lug at one end. A first small diameter hole communicating with the sprue, and a second small diameter hole communicating with an injection nozzle of an injection machine at the other end.
a cylinder having a small diameter hole and a large diameter hole between the small diameter holes, which is attached to the mold; a hollow cylindrical portion having a hole; and a flange that protrudes from the outer peripheral surface of the hollow cylindrical portion and partitions the inside of the large diameter hole into a first air chamber on the side of the mold and a second air chamber on the side of the injection nozzle. a piston having a section; during injection molding, the piston is communicated with the second air chamber, and the piston is brought into contact with the mold, so that the second small-diameter hole and the through hole cooperate to form a drill hole for forming a drawn rod; , when pulling out the spruce slug, communicates with the first air chamber to separate the piston from the mold, and then communicates the first air chamber with the first small diameter hole through a communication groove on the outer peripheral surface of the hollow cylinder part.
