Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
One kind as shown in Figure 1 from the big stroke die clamper of pressurize, including the first noumenon 1, is fixed by 1 side of the first noumenon
It is connected with the second ontology 2, the fixed form can be welding, screwing etc., and pressing plate 3, institute are hinged on the first noumenon 1
The first noumenon 1 is stretched out in the side for stating pressing plate 3, and the other side of the pressing plate 3 is located above the second ontology 2, in second ontology 2
It is provided with cavity, 2 bottom side of the second ontology is provided with the oil inlet and outlet being connected to cavity, is additionally provided in the cavity
The piston 4 of extended ontology, the external part of the piston 4 and another side contacts of pressing plate 3 are also set up in the first noumenon 1
There are spring mechanism 5, one end of the spring mechanism 5 to be 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 ontology 2 for cut off oil inlet and outlet from pressure-retaining system, at work, pressed from both sides
When 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 the pressure of spring mechanism 5 is overcome to move downward, and is pressed in mold side
Compression molding operation is realized on edge, 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 pressurize operation, when needing to unclamp mold, be detached from from pressure-retaining system so that oil inlet and outlet access, the second ontology
2 pressure releases, high pressure oil are flowed out from the oil inlet and outlet of the second ontology 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 to be jacked up upwards, pressing plate 3 is sprung back so that pressing plate 3 unclamps mold, this die clamper
In, after increasing 3 down stroke of pressing plate, due to the setting of spring mechanism 5 so that after the hydraulic oil pressure release in the second ontology 2, pressure
Plate 3 can also be sprung back upwards, the phenomenon that can not being sprung back without pressing plate 3, can not unclamp mold, to realize that die clamper is big
The requirement of stroke, while this die clamper manufacture difficulty is low, is suitble to produce in enormous quantities.
On the basis of the above, as shown in Fig. 2, described from pressure-retaining system includes carrying valve seat 6 and to block oil inlet and outlet
