Abstract

PURPOSE:To remove the hardened material attached to the resin inlet of a mold and also prevent resin dripping from the resin outlet, thus intend automation of sealing operation, by providing a sliding plate with a connecting port between the resin inlet of the mold and the resin outlet and moving the resin pouring port. CONSTITUTION:Resin is poured into a cavity 3 by making at first a slide hole 11 to coincide with a valve port 15 by operating a pneumatic cylinder 12, pressing the resin from an inlet 17 and making the resin to pass through the valve port 15, the slide hole 11 and a runner 4 by pulling an opening and shutting rod 14. Then, after standing it for predetermined time till the resin hardens, connection between the runner 4 and the valve port 15 is shut by moving a sliding plate 10 due to operation of the pneumatic cylinder 12, further the sealing resin 16 is blocked by pushing the opening and shutting rod 14 to shut the valve port 15 and the hardened material at the inlet 5 of the mold is cut off by the slide hole 11. By this, resin dripping can be prevented, though the pouring port is disconnected from the mold.
