Operation principle：
Mould 1 is arranged between solid plate 11 and moving platen 12, during high-voltage lock mould, and hydraulic oil, high pressure are passed through in control oil duct 2a
Oil pushes away guiding valve 5 to the left, until the chamfering 5a of the left end of guiding valve 5 offsets with the flange 42 of piston 4 and forms sealing, as shown in Fig. 2
At this moment, separated between the cavity in the left side of 3 inner carrier of Mode-locking oil cylinder cylinder 4 and the cavity on the right side of piston 4 by guiding valve 5 and be not communicated with.Together
When, the fuel feed hole 11a on solid plate 11 is also passed into hydraulic oil, and piston 4 is pushed away to the right, due to piston 4 is fixed on pull bar 2 and with
Pull bar 2 formation overall structure, while piston 4 is pushed away to the right, pull bar 2 is moved to right therewith, thus drive moving platen 12 to move to right and
Mould 1 is clamped, so as to realize that high-voltage lock mould is acted.
Hydraulic oil that fuel feed hole 11a is passed through and control to be passed through hydraulic oil in oil duct 2a for uniform pressure, thus both can be with
Using same oil sources, the design of hydraulic pressure oil duct can be simplified.And control oil duct 2a to be opened in the non-stress side of pull bar 2, and by
Power side (side for being connected with moving platen 12) then non-perforate, therefore in the unstressed concentration in stress side, such structure can be carried effectively
The intensity of high pull bar 2, so as to improve the service life of equipment, reduces maintenance cost.
When controlling in oil duct 2a without hydraulic oil, make 5 grams of guiding valve from the hydraulic oils being passed through of the fuel feed hole 11a on solid plate 11
The elastic force for taking spring 51 is moved to right, and the flange 42 of guiding valve 5 and piston 4 departs from, as described in Figure 3, at this moment 3 inner carriers 4 of Mode-locking oil cylinder cylinder
Turned between the cavity in left side and the cavity on the right side of piston 4, so as to realize interior circulation.And moving platen 12 is then in mould shifting oil cylinder 6
Under effect, realization is moved left and right, mobile drive pull bar 2, the synchronizing moving of piston 4 of moving platen 12.
Highly preferred embodiment of the present invention has been illustrated, and the various change or remodeling made by those of ordinary skill in the art are not
It can depart from the scope of the present invention.
