A hydraulic drive circuit for injection molding machines, characterized in that it comprises a general reservoir of liquid, constituted by the machine bed itself, a pump that injects this liquid under pressure on a tap that constitutes the general governing body, two Double acting cylinders whose pistons act, respectively, on the mechanism closes-molds and on the injection mechanism, two pairs of conduits -by any of which can be made to circulate the pressurized fluid supplied by the pump- that connect with the faucet said two cylinders, and an intermediate conduit in which a check valve is inserted and which opens into the main chamber of the cylinder corresponding to the injector mechanism, automatically varying the speed of advance of the piston, and multiplying consequently the thrust force, in the last phase of the injection process.
