とを特徴とする型締シリンダの減速機構。[Scope of Claim for Utility Model Registration] (a) A cylinder that penetrates the piston and forms an oil passage communicating between the head side and the rod side; (b) A cylinder that extends into the oil chamber from the head side end surface of the cylinder and has a rod end. (c) a disc valve that opens and closes the oil passage; (d) a switching valve for driving the disc valve that moves the disc valve to open and close the oil passage; (e) has a mold opening/closing switching valve connected to the cylinder; (f) the disc valve driving switching valve is in a position where the disc valve opens the oil passage during high-speed mold closing and mold opening; The disc valve is in the position to close the oil passage during closing brake, high-pressure mold clamping, pressure relief, and mold opening brake. This is the position that supplies oil to the booster cylinder and drains the head side and rod side of the main cylinder when the mold is opened.When the mold is opened and the mold opening brake is used, the oil in the booster cylinder is drained and oil is supplied to the head side and rod side of the main cylinder. A deceleration mechanism for a mold clamping cylinder, characterized in that the deceleration mechanism serves as a position for supplying.
