By the hinged structure connection of machine between tailgate 3,6 outer rim of brother woods column is equipped with one section of external screw thread, and mode transfer pinion gear 4 passes through interior
Screw thread is connect with the external screw thread on brother woods column 6, and the mode transfer pinion gear 4 is engaged with the molding gear 8, the mode transfer canine tooth
Wheel 8 is driven by hydraulic motor 7, and the electromagnetic induction sensor 5 is set to 8 side of molding gear, 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 the corresponding molding gear 8 of target clamp force F needs to rotate, then output signal control
Hydraulic motor 7 processed rotates, so that molding gear 8 be driven to rotate, and then drives mode transfer pinion gear 4 along 6 radial rotating of brother woods column
And moved axially along brother woods column 6, and the tailgate 3 is arranged close to the mode transfer pinion gear 4, since 3 sliding sleeve of tailgate is set to brother
On woods column 6, brother woods column 6 is equivalent to the track of tailgate 3, and mode transfer pinion gear 4 is mobile to drive the tailgate 3 along 6 axis of brother woods column
Mobile to direction, during the clamp force described in the present embodiment adjusts, specially promotion tailgate 3 is along 6 axial direction of brother woods column
It is mobile.
At the same time, the current number N of teeth of the rotation of molding gear 8 described in 5 real-time detection of electromagnetic induction sensor ', and handle
The current number N of teeth that the molding gear 8 detected rotates ' it is sent to programmable controller, programmable controller judges N's ' and N
Size relation, as N ' < N, programmable controller control hydraulic motor 7 is continued to rotate, and when N '=N, tailgate 3 is moved to
Target position, programmable controller control hydraulic motor 7 stop operating, and complete the adjustment process of clamp force.
In the embodiment of the present invention, the programmable controller calculates corresponding molding gear 8 according to target clamp force F
The specific algorithm of target rotational number N of teeth is as follows:
N=(F*L)/(Σ * K*E*A)

After wheel 8 and mode transfer pinion gear 4 are selected, which is known and determines；N is to reach target clamp force F, molding gear
8 are moved to the number of gears that target position needs to rotate from dead-center position, and wherein dead-center position is that moving template is just bonded with mold
But when not generating any clamp force, the location of mould adjusting mechanism, K is the radical of brother woods column.
It is adjusted existing for this mode of clamp force to overcome using the amount of tension of amount of tension sensor measurement brother's woods column
Various defects, the present invention use the mode of the measurement molding gear rotation number of teeth instead.Due in the die casting machine course of work, moving template
When with solid plate mode locking, brother's Lin Zhuhui stretcher strain, the present invention first moves tailgate to solid plate before mode locking, moving distance etc.
In brother's woods column stretcher strain amount, therefore, the present invention replaces being passed with amount of tension by calculating tailgate to the mobile distance of solid plate
The amount of tension of sensor measurement brother woods column.And tailgate is equal to what mode transfer pinion gear moved on brother's woods column to the mobile distance of solid plate
Distance, the Tooth Number Calculation that the mobile distance of mode transfer pinion gear can be rotated by it, and due to mode transfer pinion gear and molding gear
Therefore engagement can be detected the number of teeth of molding gear rotation by electromagnetic induction sensor and be moved to calculate tailgate to solid plate
Dynamic distance.
Therefore, the die-casting machine die-locking power in the embodiment of the present invention adjusts system, eliminates stretching quantity detection sensor, and
It is incorporated into algorithm in the programmable controller, so that the target clamp force that the programmable controller can be inputted according to user calculates
The target rotational number of teeth, meanwhile, control hydraulic motor turns to 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, greatly improve work efficiency.Meanwhile
The system does not have interference or data distortion phenomenon using digital amount signal.
Clamp force of the present invention adjusts process are as follows: the tailgate process mobile to target position from dead-center position.It is described
Target position are as follows: tailgate is moved to some position to solid plate, and clapper die spotting press cuts with scissors (the hinged structure of machine i.e. between tailgate and moving template)
After stretching, the clamp force between moving template and cover half board mold is just equal to target clamp force.
In order to guarantee the stable structure of die casting machine, in the present embodiment, the brother woods column 6 has four and rectangular frame formula point
Cloth, four Gen Gelin columns 6 are divided into the surrounding of tailgate, moving template and solid plate central axis, adaptively, the mode transfer pinion gear 4
Also it is sheathed on there are four and respectively on the four Gen Gelin column 6.The molding gear 8 is set in four mode transfer pinion gears 4
It the heart and is engaged simultaneously with four mode transfer pinion gears 4, so that four mode transfer pinion gears 4 rotate synchronously, meanwhile, increase rotating torque,
Reduce the energy consumption of hydraulic motor.
