Abstract

PURPOSE:To improve seal effect, prevent oil leakage, reduce wear of seal material by using elastic seal material to a piston inserted to a die clamping cylinder. CONSTITUTION:A movable disk 6 is advanced at a high speed by supplying oil to a booster cylinder chamber 16. A mold is closed and when oil is supplied from an oil hole 17 to a mold clamping cylinder chamber 12 to increase pressure, high pressure oil flows into oil ring grooves 11 from oil connecting holes 14 and the O-ring 10 is pushed to the inner wall of the mold clamping cylinder and seald. After the resin plasticized in a heating cylinder 9 is injected and cured in a mold cavity, the die clamping cylinder chamber 12 and the booster cylinder chamber 16 are connected to a tank and when the oil is injected from an oil hole 18 into a mold opening cylinder chamber 13, the movable disk 6 is retired as far as it does not touch the inner wall of the mold clamping cylinder because the O ring 10 or the O-ring groove is connected to the tank. Use of elastic material for the O-ring prevents wear due to sliding, leakage of oil, reduces supply of oil, economizes electric power.
