There is the space of fixed height between bar 9 and bottom plate 3, to control thickness of sample.
The design of material overflow port: 7 particulate materials being put into can not just meet the need of certain thickness sample sample preparation at blowing
It wants, is generally put into some particulate materials 7 meetings at the blowing, after particulate material heating melting, mold is under the action of outer plus-pressure more
It can be combined together, extra melting charge must be overflowed from mold, this just needs the design of material overflow port 10, which is will be upper
The outer diameter of the intermediate bar 9 of cover board 1 is slightly less than the inner hole outer diameter of intermediate ring 2, and extra melting charge can overflow from material overflow port 10.
Mould release design: heating mold and pressurize, and needs to take out sample after the mold is cooled, 10 fill out at mold flashing mouth at this time
Filled the composite material overflowed, after these composite materials are cooling with mold fitting together tightly, make mold be difficult to split, give
Sample taking-up brings certain difficulty, and the present invention has separately designed two threaded holes on upper cover plate 1 and bottom plate 3 thus, makes
When dismantling after sample, suitable screw is threaded into hole, is split mold by screw, to smoothly take out sample.
By the sharp blade equating in the sample edge of taking-up, that is, sample needed for obtaining test complex permeability, because
Thickness of sample is in mold design it has been determined that therefore obtained thickness of sample is constant, without measuring thickness of sample before test.
Mold gradually to be installed, and is put into particulate composite, then upper cover plate 1 is installed, mold portions cooperation is appropriate,
It is not susceptible to slide relatively, mold is heated on compression molding instrument and is pressurizeed, it is then that mold is cooling, bottom plate 3 will be fixed in
Between the screw of ring 2 unload, then be screwed into screw in the threaded hole on upper cover plate 1 and bottom plate 3, mold can easily be dismantled,
Sample is taken out, scabbles overlap with sharp knife edges.In the present embodiment, by taking the thickness of sample for designing 3.0mm ± 0.05mm as an example, sample
For the thickness design margin of tolerance generally within 0.05mm, obtaining two actual output thickness of sample is respectively 3.02mm, 3.04mm,
Meet needs of production.
