路。 A main pressure oil chamber into which pressure oil from the main circuit flows through a pilot-operated check valve is provided between the mold clamping cylinder and the outside diameter of the mold clamping ram, and the pressure in the main pressure oil chamber is increased by a piston. In the hydraulic circuit of the mold clamping device which attaches a cylinder to the mold clamping cylinder and moves the piston of the pressure boosting cylinder during the mold opening operation to obtain mold opening force, a circuit connecting the main circuit and the pressure boosting cylinder is A directional switching valve with a solenoid is provided, and a sequence valve is provided between the switching valve and the main circuit, so that the pressure boosting cylinder is activated when the oil pressure in the main pressure oil chamber reaches a set pressure. Hydraulic circuit for the mold opening pressure booster cylinder in the mold clamping device.
