The specific embodiment
The utility model is described in further detail below by specific embodiment
With reference to figure 1 and Fig. 2, provided a possible embodiments of the present utility model,
A kind of direct pressure mechanism of surging entirely; comprise front template (1), pull bar (2), moving platen (3), rear pattern plate (6), molar hick regulating mechanism (8) and matched moulds clamping mechanism; front template (1) is connected with rear pattern plate (6) by pull bar (2); regulating between them apart from molar hick regulating mechanism (8); moving platen (3) places between front template (1) and the rear pattern plate (6) and can move forward and backward along pull bar (2); the matched moulds clamping mechanism is installed on rear pattern plate (6) and upward and by driving mechanism is connected with moving platen (3), it is characterized in that described matched moulds clamping mechanism:
A column through hole is established at rear pattern plate (6) middle part;
One locked mode column (13) passes the column through hole of rear pattern plate (6), and its end is connected with moving platen (3); Locked mode column (13) is provided with locked mode scrobicular ring (14); The locked mode column is established mould shifting oil cylinder in (13);
One shifting formwork plunger (9) is located in the mould shifting oil cylinder of locked mode column (13), and its plunger end is connected with rear pattern plate (6);
A Mode-locking oil cylinder is established at rear pattern plate (6) middle part, and locking piston (7) middle part has in the Mode-locking oil cylinder that can allow through hole that locked mode column (13) passes and place rear pattern plate (6);
A locked mode chuck (5) is installed on the locking piston (7);
One chuck drive oil cylinder (10) is installed on locking piston (7) and goes up and be connected in locked mode chuck (5); The locked mode scrobicular ring of establishing on the locked mode column (13) (14) is corresponding with locked mode chuck (5), and locked mode chuck (5) can enter in the locked mode scrobicular ring (14) during mode-lock status.
The back long section of the locked mode column (13) of this example and the cross section of locking piston (7) centre bore are the identical spline-shaped of shape; the degree of depth of locked mode scrobicular ring (14) is identical with the spline tooth depth; locked mode chuck (5) is the disk that the center has splined hole; the shape of splined hole conforms to locked mode column (13) cross section, drives locked mode chuck (5) rotation by chuck drive oil cylinder (10) and makes the inner spline gear of locked mode chuck (5) enter/leave locked mode scrobicular ring (14).
One locked mode column is comforted frame (4) and is installed on the rear pattern plate (6), and bogie wheel (11) is installed on the locked mode column and comforts that frame (4) is gone up and contact with locked mode column (13) supporting.
One safety guard (12) is located at the rear end of rear pattern plate (6), and the plunger end of shifting formwork plunger (9) is connected with rear pattern plate (6) by safety guard (12).
The course of work:
Die sinking; the back cavity of mould shifting oil cylinder (9) and the ante-chamber of Mode-locking oil cylinder fill hydraulic oil; locking piston (7) and locked mode column (13) are under the effect of hydraulic oil; past rear pattern plate (6) rear is to moving; because locked mode column (13) is directly installed on moving platen (3) back; move behind the locked mode column (13), it is close to rear pattern plate (6) one sides to drive moving platen (3), thereby realizes the die sinking action.The cross section of locked mode column (13) conforms to the middle hole shape of locked mode chuck (5) that is passed and locking piston (7); be centrosymmetric spline-shaped (this example is 8 grooves, 8 teeth); and between the mesopore of locked mode column (13) cross section and locked mode chuck (5) and Mode-locking oil cylinder piston (7) free gap is arranged; allow locked mode column (13) in the mesopore of locked mode chuck (5) and Mode-locking oil cylinder piston (7), to move axially; so; locked mode column (13) passes the mesopore of locked mode chuck (5) and Mode-locking oil cylinder piston (7), can be inserted into the back of Mode-locking oil cylinder piston (7) always.During this period of time, the rod chamber of chuck drive oil cylinder (10) fills hydraulic oil, makes locked mode chuck (5) keep the position that allows locked mode column (13) axis to move.Along with moving behind the locked mode column (13), when the front end of shifting formwork plunger (9) contacted with the end of mould shifting oil cylinder (9), mould shifting oil cylinder (9) quit work, and this is the maximum die sinking position of moving platen (3).
Matched moulds, when the ante-chamber of mould shifting oil cylinder (9) fills hydraulic oil, the ante-chamber of Mode-locking oil cylinder (7) keeps filling hydraulic oil simultaneously, and at this moment, locked mode column (13) promotes moving platen (3) and moves to the front template direction under the hydraulic fluid pressure effect, thereby realizes mould assembling action.When moving platen (3) touch when stopping after adorning mould, the groove of locked mode column (13) just moves on to and the corresponding position of locked mode chuck (5) (this point can be adjusted to the right place by the molar hick regulating mechanism is disposable).Because depth of groove conforms to the height of spline tooth, groove width is corresponding with locked mode chuck (5) thickness, so locked mode chuck (5) can rotate around axis.At this moment, the hydraulic oil of chuck drive oil cylinder (10) commutates rapidly, and top rodless cavity fills hydraulic oil, and the oil cylinder piston bar promotes locked mode chuck (5) inhour downwards and just rotates 1/2 spline tooth angle of circumference.Make inner spline gear on the locked mode chuck (5) just block the external spline teeth of locked mode column (13).After locked mode chuck (5) is finished above action; Mode-locking oil cylinder (7) is commutation rapidly; back cavity (major diameter chamber) fills hydraulic oil; oil pressure makes locking piston (7) produce very big axial force forward; this axial force is passed to locked mode chuck (5) by locking piston (7); pass to locked mode column (13) by locked mode chuck (5) again, locked mode column (13) withstands moving platen (3) and finishes the locked mode function.At this moment the stroke of locking piston (7) only is the displacement that above-mentioned several member and mould are eliminated gap and stress deformation, so the stroke of locking piston (7) is very short, realizes that with this high pressure low speed closes the tightly requirement of (locked mode).
Characteristics of the present invention are: adopt single cylinder independence shifting formwork, single cylinder independence locked mode, the easier perfect high velocity, low pressure of realizing The folding mould requirement of matched moulds and low speed heavy pressure locked mode and smooth-going transition. Simple and compact for structure, easy to manufacture, durable in use.
