The solid plate 1, moving platen 2, tailgate 3 are coaxially disposed and are equipped with four Gen Gelin posts 6 jointly, the moving platen 2
Connected between tailgate 3 by the hinged structure of machine, the outer rim of brother woods post 6 is provided with one section of external screw thread, and mode transfer little gear 4 is by interior
Screw thread is connected with the external screw thread on brother woods post 6, and the mode transfer little gear 4 engages with the mode transfer gear wheel 8, the mode transfer canine tooth
Wheel 8 is driven by hydraulic motor 7, and the electromagnetic induction sensor 5 is located at the side of mode transfer gear wheel 8, for detecting the tune
The number of teeth that mould gear wheel 8 rotates, the hydraulic motor 7 and the electromagnetic induction sensor 5 are electric with the programmable controller
Connection.
The programmable controller can receive the target clamp force F of user's input, and the rear programmable controller is according to it
In programmed algorithm calculate the number N of teeth that mode transfer gear wheel 8 corresponding to target clamp force F needs to rotate, then output signal control
Hydraulic motor 7 processed rotates, and so as to drive mode transfer gear wheel 8 to rotate, and then drives mode transfer little gear 4 along the radial rotating of brother woods post 6
And moved axially along brother woods post 6, and the tailgate 3 is set close to the mode transfer little gear 4, because the slip cap of tailgate 3 is located at brother
On woods post 6, equivalent to the track of tailgate 3, mode transfer little gear 4 moves so as to drive the tailgate 3 along the axle of brother woods post 6 brother woods post 6
Moved to direction, during the clamp force adjustment described in the present embodiment, specially promote tailgate 3 along the axial direction of brother woods post 6
It is mobile.
At the same time, electromagnetic induction sensor 5 detects the current number N of teeth that the mode transfer gear wheel 8 rotates in real time ', and handle
The current number N of teeth that the mode transfer gear wheel 8 detected rotates ' send to programmable controller, programmable controller judges N's ' and N
Magnitude relationship, as N ' ＜ N, Controlled by Programmable Controller hydraulic motor 7 is rotated further, and when N '=N, tailgate 3 is moved to
Target location, Controlled by Programmable Controller hydraulic motor 7 stop operating, and complete the adjustment process of clamp force.
In the embodiment of the present invention, programmable controller mode transfer gear wheel 8 according to corresponding to being calculated target clamp force F

The length of shape, in embodiments of the present invention, when the effective length of brother's woods post reaches target location for tailgate 3, solid plate 1 and brother woods
The fixed connection point of post 6 is the distance between to the threaded connection point of the mode transfer little gear 4 and brother woods post 6；Σ is rotation one
Gear on mode transfer gear wheel 8 makes tailgate 3, and with respect to the offset of solid plate 1, the parameter is relevant with gear mechanism, when mode transfer canine tooth
After wheel 8 and mode transfer little gear 4 are selected, the parameter is known and determination；N is to reach target clamp force F, mode transfer gear wheel
8 are moved to target location from dead-center position needs the number of gears that rotates, and wherein dead-center position is that moving platen is just bonded with mould
But when not producing any clamp force, the location of mould adjusting mechanism, K is the radical of brother's woods post.
In order to overcome using the amount of tension of stretching quantity sensor measurement brother's woods post to adjust existing for this mode of clamp force
Various defects, the present invention use the mode of the measurement mode transfer bull gear drive number of teeth instead.Due in the die casting machine course of work, moving platen
During with solid plate locked mode, brother woods post meeting stretcher strain, the present invention first moves tailgate to solid plate before locked mode, displacement etc.
In brother's woods post stretcher strain amount, therefore, the present invention replaces being passed with amount of tension by calculating distance that tailgate move to solid plate
Sensor measures the amount of tension of brother's woods post.And tailgate is equal to what mode transfer little gear moved on brother's woods post to the distance that solid plate moves
Distance, the Tooth Number Calculation that the distance that mode transfer little gear moves can be rotated by it, and due to mode transfer little gear and mode transfer gear wheel
Engagement, therefore, it can be moved by electromagnetic induction sensor to detect the number of teeth of mode transfer bull gear drive to calculate tailgate to solid plate
Dynamic distance.
Therefore, the die-casting machine die-locking power adjustment system in the embodiment of the present invention, eliminates stretching quantity detection sensor, and
Algorithm is incorporated into the programmable controller so that the target clamp force that the programmable controller can input according to user calculates
The target rotational number of teeth, meanwhile, control hydraulic motor, which rotates, arrives the target rotational number of teeth, completes the adjustment process of clamp force.
The system can be automatically performed the adjustment of clamp force, effectively reduce cost, substantially increase operating efficiency.Meanwhile
The system does not have interference or data distortion phenomenon using digital amount signal.
Clamp force of the present invention adjusts process：The process that tailgate moves from dead-center position to target location.It is described
Target location is：Tailgate is moved to some position, clapper die spotting press hinge (the hinged structure of machine i.e. between tailgate and moving platen) to solid plate
After stretching, the clamp force between moving platen and cover half board mold is just equal to target clamp force.
In order to ensure the Stability Analysis of Structures of die casting machine, in the present embodiment, the brother woods post 6 has four and rectangular frame formula point
Cloth, four Gen Gelin posts 6 are divided into the surrounding of tailgate, moving platen and solid plate central shaft, adaptively, the mode transfer little gear 4
