It realizes to use to be driven by electricity and can meet thrust requirements, while can achieve the purpose of mode locking using special structure design.
The technical solution adopted by the present invention is that:
A kind of driving of open mold and self-locking structure, including moving die plate, fixed form, connecting lever component, servo motor, transmission
Axis；Servo motor is set to the back side of fixed form, and connecting lever component is equipped with several groups, is symmetrically distributed in the two sides of fixing mould, often
Side is respectively driven by servo motor, and every group of connecting lever component includes thread, connecting lever, rocker arm, thread one end and movement
Mold, which is threadedly coupled, to be fixed, and the other end and connecting lever one end are hinged, and the connecting lever other end and one end are hinged, the rocker arm other end and one
Transmission shaft is fixed, and transmission shaft is driven by servo motor and rotated.
In above-mentioned technical proposal, further, the connecting lever component shares four groups.
Further, the servo motor is equipped with speed reducer.
Further, the power output of the servo motor passes through shaft coupling and transmission axis connection.
Further, the fixing mould is equipped with bearing block, and transmission shaft is connect with bearing block by bearing.
Further, the connecting lever and rocker arm junction are equipped with grease nipple.
The beneficial effects of the present invention are:
The driving of moving die plate open mold may be implemented by connecting lever component in the present invention, final closed and locked, and open mold mistake
Cheng Caiyong is driven by electricity completion.

Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
Referring to Fig.1,2, it is only used for for open mold of the present invention driving and a kind of specific implementation of self-locking structure, the example
Interpretation the solution of the present invention, not limitation of the invention.The molding driving and self-locking structure include: moving die plate 1, consolidate
Solid plate 2, connecting lever component 3,4. servo motor 5 of gear-box, transmission shaft 7；Servo motor 5 has two, set on the back of fixed form 2
Face, connecting lever component 3 are equipped with four groups, are symmetrically distributed in the two sides of fixed form 2 two-by-two, and every side is respectively driven by a servo motor 5,
Every group of connecting lever component 3 includes thread 3-1, connecting lever 3-3, rocker arm 3-5, and the one end thread 3-1 and 1 screw thread that moves moulds connect
Connect fixation, the other end and the one end connecting lever 3-3 are hinged, and the connecting lever 3-3 other end and the one end rocker arm 3-5 are hinged, the rocker arm 3-5 other end with
One transmission shaft 7 is fixed, and 7 one end of transmission shaft is connect with the bearing block 8 being fixed on fixed form by bearing, and the other end passes through connection
The output axis connection of axis device 6 and servo motor, in addition, servo motor can also first connect driving transmission shaft rotation after speed reducer 4.
Such as Fig. 3-7, the specific work process and original by being opened extremely molding of open mold driving of the invention and self-locking structure
It manages as follows:
A such as Fig. 3, rocker arm 3-5 and thread 3-1 linear state, and with rocker arm from connecting end of transmission shaft to connecting lever
From the point of view of the direction of connecting pin, the direction is directed toward thread 3-1, and mold is in an open state at this time, as shown in Figure 9.Maximum distance
Control can be adjusted by thread 3-1.
B such as Fig. 4, rocker arm 3-5 rotation, acts on connecting lever 3-3 and pulls thread 3-1, make 1 movement that moves moulds.
C such as Fig. 5, rocker arm 3-5 continues to rotate, until mold stroke just arrives half when it is in 90 ° with thread 3-1, this
When mould-locking structure power be in minimum state, be only entirely the multiple that amplifies through speed reducer 4 of band-type brake of servo motor 5 to lock.
Usually mold will not above pause in application at this time.Such as Figure 10.
D such as Fig. 6, rocker arm 3-5 continue rotation rounding 90 ° of positions and do work, in mold clamp.
E such as Fig. 7, rocker arm 3-5 and thread 3-1 linear state, and direction and thread 3-1 opposite location,
Mold is closed at this time, such as Figure 11.Mode locking power maximizes, and mode locking power depends on the rigidity of material.
In mold moving process, mode locking power is in U-shaped (as shown in Figure 8), when mold is fully opened with closing, lock
Mould power is maximum.
