Abstract
The utility model relates to a hydraulic cohesion expansion mechanism, which comprises an oil cylinder body seat, an oil cylinder piston body, an oil cylinder cover seat, an expansion inclined block and a mould clamping pull rod. In the hydraulic mould clamping mechanism of injection molding machinery and die casting molding machinery, the outer circular face of the mould clamping pull rod is directly cohered and enclasped through the cohesion expansion mechanism; thereby, the cohesion is gearless expansion cohesion; the cohesion position does not need to be regulated or detected; the time of the movement can be directly canceled, and thereby, the cohesion period can be effectively shortened and the production efficiency of the machine is improved; due to the fact that any accurate cohesion position control does not need to be carried out, the demands on a control system are lowered therewith, the cost of the complete machine is reduced and the stability and the reliability of the complete machine are improved; the cohesion position of the mould clamping pull rod does not need tooth turning, and the effective tensile stressed area is biggest, and thereby, a larger mould clamping force can be borne. The diameter of the pull rod of the machine of the same tonnage can be designed to be smaller, and thereby, the machine cost is reduced. The hydraulic cohesion expansion mechanism does not have stress concentration, the pull rod is evenly stressed, and therefore, the service life of the pull rod is prolonged.
Description
Affiliated technical field
The utility model relates to a kind of hydraulic pressure obvolvent expansion mechanism in the hydraulic pressure locked mode part of injection mo(u)lding machinery and die cast machinery.
Background technology
Traditional obvolvent device that needs is earlier to the obvolvent of locked mode pull bar and could realize the hydraulic lock mold mechanism of high-voltage lock mould after holding tightly; the obvolvent principle of its obvolvent device: the ring-like alveolus obvolvent that a kind of obvolvent device of band type tooth is corresponding with the locked mode pull bar also makes tooth and alveolus locking, thereby makes obvolvent device and locked mode pull bar reach locking state.To align the tooth position earlier before the obvolvent device of this band type tooth and the obvolvent of locked mode pull bar, not only need consuming time to the tooth position, realize that accurate contraposition also needs complicated controlling organization, repeatedly the obvolvent meeting occur on the obvolvent device and the locked mode pull bar on the mechanical wear of tooth, the locked mode pull bar tooth of getting on the bus can reduce the intensity of pull bar.
Summary of the invention
Technical problem to be solved in the utility model: a kind of hydraulic pressure obvolvent expansion mechanism is provided, this mechanism is according to conical surface principle, adopt hydraulic thrust to make the swelling skewback bloated more tight more in cooperating the conical surface, thereby force to produce strain between the periphery of the interior ring surface of swelling skewback and locked mode pull bar and produce the power of holding tightly, thereby realize the anodontia obvolvent and lock the locked mode pull bar.
The utility model solves the technical scheme that its technical problem adopts: a kind of hydraulic pressure obvolvent expansion mechanism, and it comprises cylinder body seat, oil cylinder piston body, oil cylinder cage, swelling skewback, locked mode pull bar; Cylinder body seat and oil cylinder cage are by being fastenedly connected the formation one, the oil cylinder piston body can move at the inner chamber of cylinder body seat and oil cylinder cage, the swelling skewback is contained between oil cylinder piston body and the cylinder body seat and empty being enclosed within on the periphery of locked mode pull bar, the locked mode pull bar is contained in the center of whole obvolvent expansion mechanism, the oil cylinder piston body is provided with exterior bayonet slot near an end cylindrical of swelling skewback side, the interior fenestra of one side of swelling skewback is provided with inner card cage and can cooperates with the exterior bayonet slot of oil cylinder piston body near swelling skewback side, the opposite side male cone (strobilus masculinus) of swelling skewback cooperates with the inner conical surface of cylinder body seat, the tapering of the male cone (strobilus masculinus) of swelling skewback is less than 45 °, the basic size radius of swelling skewback inner arc surface is slightly larger than half of basic size diameter of locked mode pull bar, the swelling skewback processes into to be severed one behind the revolving body the most at last and is seamed into and is one and opens the limit body, stick on the exterior bayonet slot of oil cylinder piston body after the inner card cage diameter support greatly with the swelling skewback during installation, the swelling skewback opens the limit and can make the swelling skewback radius of inner arc surface shrinks under the external force effect at center having radially in strain, the limit of opening of swelling skewback produces elasticity and does not flick the inner conical surface that the male cone (strobilus masculinus) that makes the swelling skewback is pasting the cylinder body seat when footpath outward force not, and the interior circle of swelling this moment skewback is with regard to the cylindrical of release lock die drawing bar and produce the gap; Can make the oil cylinder piston body push away the swelling skewback by hydraulic thrust moves to cylinder body seat direction, the oil cylinder piston body was pressed the inner card cage end face of swelling skewback and was made the male cone (strobilus masculinus) of swelling skewback press tighter and tighter with the inner conical surface that matches of cylinder body seat near the end face of swelling skewback side this moment, by conical surface principle, thereby this thrust can produce to the component at locked mode pull bar center and make the internal circular surfaces of swelling skewback and the periphery of locked mode pull bar between produce strain and produce the power of holding tightly, realize the obvolvent function; Can make the oil cylinder piston body to oil cylinder cage side shifting by reverse hydraulic thrust, thereby the exterior bayonet slot of oil cylinder piston body just can stick the inner card cage of swelling skewback and haul the swelling skewback and continue mobile micro-displacement removal conical surface thrust towards oil cylinder cage side together after the oil cylinder piston body moves micro-displacement, the elasticity that the limit is opened in the utilization of swelling skewback itself makes its male cone (strobilus masculinus) keep contacting with the inner conical surface of cylinder body seat, the interior circle of swelling skewback and the cylindrical of locked mode pull bar then produce the gap, finish and open the obvolvent function.
The beneficial effects of the utility model:
1. because obvolvent is to belong to anodontia swelling obvolvent, need not to adjust the obvolvent position, need not to detect the obvolvent position, the time of these actions can directly be cancelled, and can effectively shorten the obvolvent cycle, improves the production efficiency of machine; Because need not to do any accurate obvolvent Position Control, the requirement of control system is decreased, the complete machine cost reduces, and the stability of complete machine and reliability improve.
2. the obvolvent position of locked mode pull bar need not the car tooth, and effectively tension lifting surface area maximum can be born bigger clamp force, with the pull bar diameter of tonnage machine can design littler, reduce machine cost; Do not have stress to concentrate, pull bar is stressed evenly, improves the service life of pull bar.
