On the outer circumference of the valve portion 5 fitted with the nozzle body 1 at the tip of the needle valve 4, a depth of 0.
The V-shaped groove 13 within 1 mm is cut, and the peak portion is sharply formed. A motor shaft 10 from a motor 11 is rotatably penetrated through the center of the needle valve 4, the tip side of which has a large diameter, and the distal end surface 18 is formed with parallel grooves so that the cross section has a sawtooth shape. ing.

At this time, the tip end surface 18 is rotated by the motor 11. Since the ridges of the V-shaped groove 13 are sharp, the needle valve 4 pushes the glass filler in the resin of the injection port 3 completely and moves forward to close the injection port 3. Further, since the most distal end surface 18 of the motor shaft 11 is rotated even when the product is taken out of the mold, the V-shaped groove 13 of the needle valve 4 is blocked by this, and this groove is as shallow as 0.1 mm or less. Therefore, the resin does not leak. After that, when the injection port 3 is opened again, oil is flown into the hydraulic cylinder 14 by the pump 16, so that the needle valve 4 is retracted without oil leakage.
