Described locked mode cylinder plate floats with the locked mode plate and is connected, and leaves the gap between locked mode cylinder plate and the locked mode plate.That is to say that locked mode cylinder plate floats and to be connected on the locked mode plate, locked mode cylinder plate is under the oil pressure effect after the supercharging, the locked mode plate is done apart from less moving relatively, reaches locked mode.
Bump against locked mode cylinder plate bottom for fear of push rod, described locked mode cylinder plate bottom is provided with is convenient to the blind hole of stepping down that booster rod inserts.
Enter into piston between the end face and plunger shaft bottom surface of plunger shaft bottom surface for the ease of oil, the end face of described piston towards the plunger shaft bottom surface has the oil-feed hole of being convenient to oil-feed.
For fear of the seepage of oil, the endoporus of described piston is provided with at least two sealing rings, and the outer radius of piston also is provided with at least two sealing rings.
Described fixed mechanism comprises the lock pin cylinder, the lock pin cylinder is fixed on the locked mode frame, terminal at least one lock pin that connects of the push rod of lock pin cylinder, the locked mode frame is provided with the lockpin hole corresponding with lock pin, also be provided with the lockpin hole corresponding on the locked mode plate with lock pin, lock pin inserts the lockpin hole on the locked mode frame, the lockpin hole on the locked mode plate successively, so just the locked mode plate can be fixed on the locked mode frame.That is to say that in the process of locked mode, at first, fixed mechanism is fixed to the locked mode plate on the locked mode frame, then, booster body begins the supercharging locked mode again.
The utility model beneficial effect against existing technologies is, need not to dispose hydraulic pump and hydraulic system, need not elbow-bar mechanism, adopts common cylinder, the locked mode effect of realizing ideal, and the input that has promptly reduced in the device fabrication process has reduced energy consumption again significantly.

Fig. 2 is that the A-A of preferred embodiment is to cutaway view;
Fig. 3 is that the B-B of preferred embodiment is to cutaway view.
The specific embodiment
As Figure 1-3, the clamping mechanism of the injection machine in this preferred embodiment comprises fixed mechanism, booster body, and fixed mechanism is connected with booster body, and fixed mechanism and booster body all are located on the frame 11.
Described booster body comprises locked mode frame 6, oil cylinder 14, locked mode plate 3, locked mode cylinder plate 1, piston 2, pressurized cylinder 8, and described fixed mechanism comprises lock pin cylinder 7.The fixedly connected mould 9 in locked mode cylinder plate 1 right side, locked mode cylinder plate 1 lower end slidably is located on the slide rail 10 of frame 11, and driving mechanism links to each other the motion of drive booster body with locked mode cylinder plate 1.
Described locked mode cylinder plate 1 floats with locked mode plate 3 and is connected, leave gap 16 between locked mode cylinder plate 1 and the locked mode plate 3, the end face that locked mode cylinder plate 1 is connected with locked mode plate 3 has plunger shaft, piston 2 is placed in the plunger shaft, the end face of piston 2 towards the plunger shaft bottom surface has the oil-feed hole 203 of being convenient to oil-feed, pressurized cylinder 8 is fixed on the locked mode plate 3, the push rod 4 of pressurized cylinder 8 passes the through hole 302 on the locked mode plate 3, through hole 202 on the piston 2, insert in the blind hole 102 of stepping down of locked mode cylinder plate 1 bottom, through hole 202 sidewalls of piston 2 have fuel feed hole 201, this fuel feed hole 201 is connected oil cylinder 14 by the oil suction chamber 101 of locked mode cylinder plate 1 with oil inlet pipe 15 successively, and the cross-sectional area of piston 2 is greater than the cross-sectional area of push rod 4.
Through hole 202 sidewalls of described piston 2 are provided with a plurality of sealing rings 12, and the side up and down of piston 2 also is provided with a plurality of sealing rings 12.
Introduce the course of work below:
The first step: driving mechanism is by promoting 1 motion of locked mode cylinder plate, drive whole booster body motion, lockpin hole 301 up to locked mode plate 3 moves to lock pin 5 belows, lock pin 5 inserts lockpin hole 301 on the uppermost locked mode plate 3 successively, is positioned at the lockpin hole 601 on the middle locked mode frame 6, the lockpin hole 301 on the nethermost locked mode plate 3 then, locked mode plate 3 is fixed on the locked mode frame 6, and locked mode frame 6 is fixed on the frame 11.
Second step: the space between 203 is cheated in the oil in the oil cylinder 14 is sent oil into piston 2 by oil inlet pipe 15, oil suction chamber 101, fuel feed hole 201 successively under gas pressure through hole 202, the blind hole of stepping down 102, oil-feed, the booster rod 4 of pressurized cylinder 8 travels forward, behind the through hole 202 by piston 2, oil between the blind hole 102 of stepping down, the oil-feed hole 203 is applied pressure, because the Incoercibility of oil, this pressure forms a big power by the amplification of piston 2 towards the end face of plunger shaft bottom surface.Owing to leave the gap between locked mode cylinder plate 1 and the locked mode plate 2, so this power presses to locked mode plate 3 with piston 2, pushes locked mode cylinder plate 1 to mould 9 simultaneously.The cross-sectional area of piston 2 is greater than the cross-sectional area of push rod 4, the cross-sectional area of piston 2 is 40 times of cross-sectional area of booster rod 4 in the present embodiment, therefore can produce 40 times clamp force, bigger if desired clamp force can adopt the bigger piston of cross-sectional area 2.
Described is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Be all equivalents of being done according to claim scope of the present utility model, be the utility model claim scope and cover.
