Specific embodiment specific embodiment

The technological means and effect taken further to illustrate the present invention to reach predetermined goal of the invention, below in conjunction with attached Figure and preferred embodiment to specific embodiment, structure, feature and its effect of the present invention, are described in detail as after.

Refer to shown in Fig. 1 to Fig. 5, the pressing structure 100 of the embodiment of the present invention, including pedestal 10, pressure applicator 20, with And mold 30.

Shown in Figure 1, pedestal 10 is the rectangular plate-like structure with certain thickness and intensity, and pedestal 10 is horizontally disposed, The lower surface quadrangle of pedestal 10 is symmetrically arranged with non-slip mat 12, and non-slip mat 12 is generally made of rubber or high molecular material, But not limited to this.The upper surface of pedestal 10 is fixedly connected with pressure applicator 20, and it can be welding that this, which is fixedly connected, rivet, but not It is limited to this.

It refers to shown in Fig. 1, Fig. 2, Fig. 5, pressure applicator 20 includes operation console 22, pressure provides device 24, mold fixes dress Put 26 and pressure relief device 28.

Operation console 22 is hollow or hollow part rectangular parallelepiped structure, the lower surface of operation console 22 and the upper surface of pedestal 10 It is fixedly connected, the size of the upper surface for being sized to be slightly smaller than pedestal 10 of the lower surface of operation console.

With reference to shown in Fig. 1 referring again to Fig. 2, pressure provides device 24 and includes jack ontology 241, oil conservator 242, unidirectional Valve 243, pressure bar portion 244, operation handle 245, pressure gauge 246.

Jack ontology 241 is in tube-in-tube structure closed at both ends.In jack ontology 241 includes inner sleeve 2412 and is sheathed on Outer sleeve 2414 outside sleeve 2412, the height of the inner sleeve 2412 of jack ontology 241 are more than the height of outer sleeve 2414, The diameter of outer sleeve 2414 is more than the diameter of inner sleeve 2412.The upper end closed of inner sleeve 2412, the lower end of inner sleeve 2412 is not Closing, the lower end of inner sleeve 2412 are provided with the first circular limiting section 2416 for protruding from 2412 outer wall of inner sleeve, inner sleeve The upper end of cylinder 2412 is fixedly connected with the lower surface of die table device 26.The lower end closed of outer sleeve 2414, outer sleeve 2414 Upper end do not close, the upper end of outer sleeve 2414 is provided with inwardly projecting the second circular limiting in 2414 inner wall of outer sleeve Portion 2418, the lower end of outer sleeve 2414 are fixedly connected with the upper surface of operation console 22.Inner sleeve 2412 can be relative to outer sleeve 2414 axial movements, and realize inner sleeve 2412 and outer sleeve under the first limiting section 2416 and the cooperation of the second limiting section 2418 2414 do not depart from mutually.It is provided between the inner wall of the second limiting section 2418 of outer sleeve 2414 and the outer wall of inner sleeve 2412 close Seal 2419.Inner sleeve 2412 forms a closed area 2417 connect, variable volume with outer sleeve 2414, i.e., when thousand When jin top 241 internal pressure of ontology is more than external pressure, internal pressure pushes inner sleeve 2412 to rise vertically and stretch out outer sleeve 2414, while the volume of closed area 2417 becomes larger；When 241 internal pressure of jack ontology is less than external pressure, outside pressure Dynamic 2412 retraction outer sleeve 2414 of inner sleeve is pushed, while the volume of closed area 2417 becomes smaller therewith.Jack ontology 241 Closed area 2417 in be always maintained at full of hydraulic oil, hydraulic oil when closed area 2417 change inside it also becomes therewith Change.

Shown in Figure 5, oil conservator 242 is set to the hollow space inside operation console 22, and one is stored in oil conservator 242 Quantitative hydraulic oil.Oil conservator 242 is connected with jack ontology 241, i.e., the hydraulic oil inside oil conservator 242 can flow into Or the inside of outflow jack ontology 241.

Check valve 243 is set on the pipeline connected between jack ontology 241 and oil conservator 242, and check valve 243 is only permitted Perhaps oil conservator 242 injects hydraulic oil into jack ontology 241, without allowing reverse operation.
