< moves >
As described above, this press molder 100 possess by pressurized shaping thing 1 from adding of top pressurization present a theatrical performance as the last item on a programme 13, with add present a theatrical performance as the last item on a programme 13 opposed and pressurized shaping thing 1 is added from the pressurization of below present a theatrical performance as the last item on a programme 5 and by under add the 5 back brace cylinders 19 that boost upward of presenting a theatrical performance as the last item on a programme.Under this, adding presents a theatrical performance as the last item on a programme 5 is provided with the harvesting forming pressure container 3 of pressurized shaping thing 1 and the housing 2 that pressurized shaping thing 1 is surrounded, so that housing 2 becomes roughly the same height with forming pressure container 3.And, by pressurized shaping thing 1 take with housing 2 and forming pressure container 3 in the form of roughly the same height is positioned in forming pressure container 3.In addition, on this, add and present a theatrical performance as the last item on a programme on 13, be provided with shaping rubber 8, be provided in the top of shaping rubber 8 and in the time of press molding to shaping rubber 8 from above apply stressed pressurization rubber 9 and keep shaping rubber 8 and the pressurization rubber pushing body (rubber-type retainer) 10 of pressurization rubber 9.
In the press molder 100 that possesses such structure, carry out following action: by making back brace cylinder 19 increase, make down to add to present a theatrical performance as the last item on a programme and 5 be close to add and present a theatrical performance as the last item on a programme on 13 so that shaping rubber 8 becomes roughly the same height with pressurization rubber pushing body 10, and by importing pressure to pressurization rubber 9, pressurized shaping thing 1 is pressurizeed and compression molding.
Such action, i.e. the processing action of the press molder 100 after press molder 100 is transported into pressurized shaping thing 1 before treatment (action, pressurized treatments action are processed in precompressed) are described.
First, process action as precompressed, before pressurization, the pressure matchmaker from low-lift pump 22 (hydraulic pressure) is only guided to back brace cylinder 19, make down to add via bar 18 and distance piece 75 risings of presenting a theatrical performance as the last item on a programme, until the lower surface of shaping rubber 8 and pressurization rubber pushing body 10 touches on the upper surface that arrives to forming pressure container 3.Now, pressurized shaping thing 1 and housing 2 form the upper surface with forming pressure container 3 roughly the same height, and shaping rubber 8 and pressurization rubber pushing body 10 form the lower surface of roughly the same height.Like this, making after the state that shaping rubber 8 and pressurization rubber pushing body 10 are more smooth, the forming pressure container 3 that has loaded pressurized shaping thing 1 and housing 2 is pressurizeed, so do not need strict location.As a result, this press molder 100 is applicable to producing continuously, and productivity ratio is higher.
In addition, like this, under to add 5 the upper surface of presenting a theatrical performance as the last item on a programme be smooth, it is smooth above adding 13 the lower surface of presenting a theatrical performance as the last item on a programme, thus can make to add present a theatrical performance as the last item on a programme 13 pressurization rubber pushing body 10 with under to add the gap of 5 the forming pressure container 3 of presenting a theatrical performance as the last item on a programme very little.As a result, be not to add press box 12 to contact such state with internal part line, but contact on whole that adds press box, and the rigidity of internal part is higher, so it is less to add the deflection of press box 12.Thereby, can make zero load stroke and the pressure stroke of back brace cylinder 19 all very little.
Then, as pressurized treatments action, make supercharger 21(high-pressure pump) action, will press matchmaker to guide to the inside of back brace cylinder 19 and pressurization rubber 9 simultaneously, the rubber 8 that makes to be shaped expands, and the pressurized shaping thing 1 of handling object is pressurizeed.That is, pressurize with back brace cylinder 19 on one side, with shaping rubber 8, housing 2 and pressurized shaping thing 1 are pressurizeed on one side simultaneously.If pressurized treatments like this, metal housing 2 is restrained, can limit the displacement radially of pressurized shaping thing 1 and by shaping rubber 8, pressurized shaping thing 1 be pressurizeed equably.
Now, as shown in Figure 6, control to become the pressure of back brace cylinder 19 and pressurization rubber 9(and then be shaping rubber 8) pressure be the such pressure pattern of same pace.The pressure that, becomes the two roughly increases simultaneously, is roughly maintained simultaneously maximum pressure, roughly reduces such pressure pattern simultaneously.
And then, as shown in Figure 6, control so that the pressure large 5～20% of the pressure ratio shaping rubber 8 of back brace cylinder 19.This for example by before the pressure of the pressure of back brace cylinder 19 and shaping rubber 8 is boosted simultaneously, first only make the boost pressure of regulation of the pressure of back brace cylinder 19 sides realize.If like this, housing 2 can not be out of shape, and pressurized shaping thing 1 can be shaped.In addition, at the pressure of back brace cylinder 19, higher than this scope, the distortion of housing 2 becomes significantly, by repeatedly pressurizeing, and the change in size of housing 2 and become and can not use.On the contrary, at the pressure of back brace cylinder 19, lower than this scope, shaping rubber 8 can not seal, and has reached damage by repeatedly pressurizeing.
In addition, pressurized shaping thing 1 is carried out to each reduced pressure treatment action after uniform pressure pressurized treatments first by the earth pressure release of pressurization rubber 9 sides, then by the earth pressure release of back brace cylinder 19 sides.In the case, the situation that also imagination contingency first discharges the pressure of back brace cylinder 19 sides because of maloperation preferably arranges check-valves in the access that pressurization rubber 9 sides are connected with back brace cylinder 19 sides.If like this, check-valves performance function, it is identical that the pressure of pressurization rubber 9 sides and the pressure of back brace cylinder 19 sides become, can prevent during exerting pressure in forming pressure container 3 be released.
By carrying out as above precompressed processing → pressurized treatments → reduced pressure treatment, can suitably carry out the dry type of pressurized shaping thing 1 respectively to uniform pressure pressurized treatments.
In the past, be located at down that to add the height adjustment of present a theatrical performance as the last item on a programme pressurized shaping thing 1, housing 2 and forming pressure container 3 on 5 more difficult.And if back brace cylinder power was uprised from the pressurization initial stage, housing 2 and/or shaping rubber 8 are out of shape or damage.But, by using the pressurized treatments of press molder of present embodiment, can eliminate these problems.
The action effect > of < press molder
