Description
Technical field
The present invention relates to a kind of air injection machine die locking mechanism, refers in particular to a kind of for hindering in low pressure casting industry
The only die locking mechanism of casting machine upper mold ascendant trend in pouring practice.
Background technology
At present, Low Pressure Casting Technology is used in cast aluminium industry by large-scale popularization.But current air injection machine, pouring into a mould
The thrust of cope plate is mainly derived from the hydraulic cylinder being fixed on cope plate during operation, so that will to hydraulic cylinder power
Ask big and stability be high, hydraulic cylinder during work easily makes liquid leakage once breaking down so that cause greatly safety it is hidden
Suffer from.Meanwhile the cantilevered air injection machine of the designed research and development of my company, stability of its cantilever design itself is poor, hydraulic cylinder effect
Active force on cantilever and column easily makes its deformation, higher to the mechanical property requirements of cantilever and column.
The content of the invention
The technical problem to be solved by the present invention is to provide a kind of air injection machine die locking mechanism, such a die locking mechanism
Working stability, can effectively reduce casting machine upper mold in pouring practice and act on power on hydraulic cylinder, especially for cantilever type low pressure
Casting machine, can reduce upper mold indirectly and act on power on cantilever and column, will to the mechanical property of cantilever and column so as to reduce
Ask.
The technical problem to be solved in the present invention with lower structure by being realized：Air injection machine die locking mechanism, including draw
Muscle, boss, semicircle cam, double end motor, axis, bearing block, AC servo motor, it is characterized in that：The air injection machine mould
Retaining mechanism can effectively reduce upper mold and act on power on hydraulic cylinder, and the air injection machine die locking mechanism is in air injection machine
Both sides mounted in pairs, and run simultaneously, there are two lacing wires in each mechanism, and two lacing wires are separately mounted to double end motor two
End, double end motor drive two lacing wires to swing up and down, and the lacing wire other end is fitted with half cam, distinguish in the both sides of side form
One lower face of installation is provided with the boss with the semi-circular recesses of the radius such as cam, prepares to pour after the completion of upper mold and side form molding
When noting operation, double end electric motor starting, driving lacing wire turns to position vertically downward so that the cam of the lacing wire other end is in side
The underface of the semi-circular recesses of mould boss, starts AC servo motor, driving two halves circular cam rotates synchronously, convex when going to
The semicircle side of wheel stops operating when coincideing with the semi-circular recesses of side form boss, and lacing wire at this time is poured by upper mold and the pulling force of side form
Note operation after the completion of, AC servo motor rotation cam, make its go to cam straight line section it is parallel with boss lower end horizontal plane and
During adjacent position, rotating backward by double end motor and lift lacing wire, air injection machine die locking mechanism is stopped since then,
Born away with upper mold.The mechanism efficiently reduces the upper mold in pouring practice and acts on power on hydraulic cylinder, especially right
In cantilever type air injection machine, upper mold is reduced indirectly and acts on power on cantilever and column, to the mechanical property of cantilever and column
Can require decline to a great extent, in the mechanism motor driving and control can directly be completed by the control system of casting machine itself.
The present invention operation principle be：After the completion of upper mold and side form molding, the die locking mechanism of air injection machine both sides
Synchronous operation, double end electric motor starting, drives lacing wire it is gone to position vertically downward, the lacing wire other end is convex at this time by axis
Wheel immediately below the groove of side form boss, start AC servo motor, make two cams rotate synchronously, when go to cam semicircle side with
Side form boss groove stops when fitting like a glove, and casting machine starts to pour into a mould work, and lacing wire at this time is by upper mold and the pulling force of side form, so as to subtract
Small upper mold acts on the power on hydraulic cylinder, after pouring practice, starts AC servo motor, it is gone to the straight line of cam
End face and boss lower end horizontal plane parallel and adjacent to position when, start double end motor, lacing wire lifted, clamping mechanism stops since then
Only work, as upper mold is lifted together, axis I and axis II are fixed on cope plate with planer type structure respectively with two pairs of bearing blocks
On, structure is more stablized, the permissible power for bearing bigger.
Advantages of the present invention：Upper mold can be acted on the power on hydraulic cylinder by air injection machine die locking mechanism, be passed through
The mechanism is acted on side form, reduces the power acted on hydraulic cylinder, is reduced to upper end hydraulic cylinder power and stability
It is required that especially for cantilever type casting machine, the power acted on cantilever and column can be reduced indirectly, reduced to outstanding
The mechanical property requirements of arm and column, the mechanism is easy to operate, and two lacing wires and cam drive it synchronously to turn by a motor respectively
Dynamic, the driving and control of motor can be completed directly by the control system of casting machine itself, easily realize automation.
Brief description of the drawings
Give an actual example and be described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the structural representation front view of air injection machine die locking mechanism.
Fig. 2 is the structural representation left view of air injection machine die locking mechanism.
Embodiment
As shown in the figure, the identical air injection machine die locking mechanism, and synchronization job are installed in air injection machine both sides.
The double end motor 6 of air injection machine die locking mechanism is fixed on cope plate 1, motor both ends by shaft coupling respectively with axis I5
It is connected with axis II8, axis I5 and axis II8 are fixed in upper mold 1 with a pair of bearing 7 with planer type structure respectively, and two lacing wires 2 divide
It is not fixed on axis I5 and axis II8, when starting double end motor 6 and making its rotation, axis I5 and axis II8 is rotated together so that both sides
Lacing wire 2 synchronously swing up and down, a half cam 4 is all installed in the end of lacing wire 2, and AC servo motor 10 is installed on axis
One end of III9, and drive two cams 4 to rotate synchronously by axis III9, the both sides of side form are installed its lower face and are provided with respectively
With the boss 3 of the semi-circular recesses of the grade radius of cam 4, when preparing pouring practice after the completion of casting machine upper mold and side form molding, make
Half cam 4 goes to the position that the semi circular surface of cam 4 matches with the semi-circular recesses of boss 3, and casting machine starts pouring practice,
Lacing wire at this time 2 is by upper mold and the pulling force of side form, so that reducing upper mold acts on power on hydraulic cylinder, when pouring practice terminates
Afterwards, two cams, 4 synchronous rotary is made to be put down to the straight line end face of cam 4 and the lower end planarea of boss 3 by AC servo motor 10
Capable and adjacent position, starting double end motor 6 goes to its opposite direction, lifts lacing wire 2, since then a work period terminate, it is low
Pressure casting machine die locking mechanism is removed together with upper mold 1.
