Abstract: A method and system of controlling a screw engaging position adjuster provided in a complex mold clamping system. A theoretical deviation of a screw engaging position is theoretically calculated on the basis of a distance by which a movable die has been moved from an origin set for a mold thickness adjustment in clamping process. A measured deviation of the screw engaging position is measured from a distance between a mold clamping cylinder and a movable platen in clamping process. The screw engaging position adjuster is so controlled that a difference between the theoretical deviation and the measuring deviation is within an allowable deviation having previously been set.

Abstract: A force to separate the mold portions for both sides of a tire, created by the pressure of a heating/pressurizing medium introduced into the tire during the vulcanization of the tire, is offset via an upper disk, a segment having protrusions at both ends, and a lower disk. A force in the radial direction to move a tread mold outward is offset via the segment. A component of force in the axial direction (vertical direction) of a radial force, created by the interposition of a sliding inclined surface between the segment and the outer ring is offset via the outer ring, a cover plate, locking claws, the upper disk, and the segment.

Abstract: A clamping cylinder system used in a diecast machine and the like and includes a clamping cylinder and a booster cylinder. The booster cylinder has two chambers different in inner diameters, and a booster piston has a small diameter portion and a large diameter portion, which correspond to the inner shapes of these chambers. During the low pressure of the clamping cylinder, the oil pressure is given to the clamping cylinder, with the booster cylinder being in non-operating condition, and, when a booster operating signal is given, the booster piston is operated. With this arrangement, a boosted pressure force in accordance with the ratio of the area between the small diameter portion and the large diameter portion of the booster piston can be obtained.

Abstract: A hydraulic press includes a press plate mounted for executing working strokes and return strokes; a hydraulic countersupport braking cylinder supported at an end zone of the working stroke for engaging the press plate at an end portion of the working stroke to cause deceleration of the press plate by the hydraulic countersupport braking cylinder; and a hydraulic shock absorber connected between the press plate and the hydraulic countersupport braking cylinder. The hydraulic shock absorber is arranged for compression from an expanded state by the press plate in an end zone of the working strokes. The hydraulic shock absorber has a shock absorber chamber containing hydraulic fluid; a throttle for setting a braking force in the shock absorber chamber to a magnitude smaller than the braking force of the hydraulic countersupport braking cylinder; and a resetting arrangement for returning the shock absorber into its expanded state.

Abstract: In the present invention, an inner space of a clamping cylinder is divided into a front oil chamber and a rear oil chamber for liquid pressure by a piston section of a clamping ram, the front oil chamber and the rear oil chamber are connected with each other by a connecting path which is bored in the piston section of the clamping ram, and the front oil chamber is connected to a charge tank via a second open-close valve. In the clamping ram, an oil chamber for mold closure and an oil chamber for mold opening are formed by slidably fitting a high speed piston therein. A first open-close valve, which opens or closes the connecting path of the piston section of the clamping ram, is slidably fitted on the rear end section of the clamping ram. An oil chamber for valve opening, which is formed between the first open-close valve and the outer face of the clamping ram, is connected to the oil chamber for mold opening via a through-hole bored in the clamping ram.
