Embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
One kind as shown in Figure 1 is fixed from the big stroke die clamper of pressurize, including the first noumenon 1,1 side of the first noumenon
The second body 2 is connected with, the fixed form can be welding, screwing etc., and pressing plate 3, institute are hinged with the first noumenon 1
The first noumenon 1 is stretched out in the side for stating pressing plate 3, and the opposite side of the pressing plate 3 is located above the second body 2, in second body 2
Cavity is provided with, 2 bottom side of the second body is provided with the oil inlet and outlet connected with cavity, is additionally provided with the cavity
The piston 4 of extended body, the external part of the piston 4 and another side contacts of pressing plate 3, also set up in the first noumenon 1
There is spring mechanism 5, one end of the spring mechanism 5 is fixed in the first noumenon 1, the other end and the pressing plate 3 of the spring mechanism 5
Contact, be additionally provided with inside second body 2 for cut off oil inlet and outlet from pressure-retaining system, at work, pressed from both sides
During tight Mould operation, high pressure liquid pressure oil is passed through in cavity from oil inlet and outlet and jacks up piston 4, and piston 4 drives pressing plate 3 around first
1 hinge joint of body rotates so that pressing plate 3 stretches out 1 end of the first noumenon and overcomes the pressure of spring mechanism 5 to move downward, and is pressed in mold side
Edge, realizes compression molding operation, after fuel cut-off, from pressurize system shutdown oil inlet and outlet, prevents hydraulic oil from flowing back so that pressing plate 3 is not
It can rebound, realize that pressurize operates, when needing to unclamp mould, depart from from pressure-retaining system so that oil inlet and outlet path, the second body
2 pressure releases, high pressure oil are flowed out from the oil inlet and outlet of the second body 2, and pressing plate 3 loses with spring contact jaw and upwards pressure, coiling machine
Structure 5 resets, and pressing plate 3 is stretched out 1 end of the first noumenon jacks up upwards, and pressing plate 3 is sprung back so that pressing plate 3 unclamps mould, this die clamper
In, after 3 down stroke of pressing plate is increased, due to the setting of spring mechanism 5 so that after the hydraulic oil pressure release in the second body 2, pressure
Plate 3 can also be sprung back upwards, can not be sprung back without pressing plate 3, can not unclamp the phenomenon of mould, so as to can realize that die clamper is big
The requirement of stroke, while this die clamper manufacture difficulty is low, is adapted to produce in enormous quantities.
On the basis of the above, as shown in Fig. 2, described include carrying valve seat 6 and can block oil inlet and outlet from pressure-retaining system
Poppet valve 7, described carry in valve seat 6 are provided with pressure release bar 8, and the pressure release bar 8 is fixed with pressure release piston away from 7 one end of poppet valve
9, the pressure release piston 9 is arranged in pressure release oil cylinder 10, pressure release oil inlet and outlet is additionally provided with the pressure release oil cylinder 10 so that let out
Pressure oil can drive pressure release piston 9 to be moved to 8 direction of pressure release bar, further include 7 reset seat of poppet valve, 7 reset seat of poppet valve with
The first spring 11 is provided between poppet valve 7, when the first spring 11 in a state of nature when, poppet valve 7 head into carry valve seat 6 will
Oil inlet and outlet is cut off, and when carrying out pressurize operation, after fuel cut-off, poppet valve 7 springs back under the action of the first spring 11 and heads into
Carry in valve seat 6 so that oil inlet and outlet open circuit, hydraulic oil can not flow back, so as to fulfill pressure holding effect, when needing pressure release, let out
Pressure oil is flowed into pressure release oil cylinder 10 from pressure release oil inlet and outlet, and driving pressure release piston 9 is moved to 8 direction of pressure release bar, and pressure release bar 8 heads on
Poppet valve 7 is allowed to depart from carrying valve seat 6, so that the hydraulic oil in the second body 2 can be flowed out from oil inlet and outlet, realizes
Pressure release, so as to unclamp mould.
On the basis of the above, as shown in Figure 1, the spring mechanism 5 includes spring and the spring compressor being set on spring, institute
State spring compressor to contact with pressing plate 3, using spring compressor and the composite construction of spring, the intensity of spring mechanism 5 can be increased, increase bullet
The service life of spring mechanism 5.
On the basis of the above, as shown in Figure 1, the piston 4 is provided with annular groove along border, it is respectively arranged with the annular groove
Sealing ring, dustband and back bracket ring, set sealing ring and back bracket ring to prevent hydraulic oil from being flowed out from 2 top of the second body, institute
Stating the setting of dustband can prevent external dust from entering in high pressure oil, so as to be impacted to the lifting of piston 4.
Particular embodiments described above, has carried out the purpose of the present invention, technical solution and beneficial effect further in detail
Describe in detail it is bright, it should be understood that the foregoing is merely the present invention specific embodiment, be not intended to limit the invention, it is all
Within the spirit and principles in the present invention, any modification, equivalent substitution, improvement and etc. done, should be included in the guarantor of the present invention
Within the scope of shield.
