The specific embodiment
Below in conjunction with specific embodiment the utility model is specifically described.
As shown in Figure 1 to Figure 3, static pressure air-exhaust mold cores such as oiled-plate method formula, comprise the matrix 1 that metal material is made, rubber-like glue-line 2, oiled-plate method 3 and hollow screw 4, matrix 1 is provided with oil inlet passage 11, exhaust passage 12 and concave surface 13, described glue-line 2 is fixed in 13 li of the concave surfaces of matrix 1, glue-line 2 is divided into skin 21 and internal layer 22, oiled-plate method 3 is between skin 21 and internal layer 22, the skin 21 of glue-line 2 and internal layer 22 are blended in and are wrapped in oiled-plate method 3 together, oiled-plate method 3 is provided with a plurality of hydraulic pressure hole 31 and screw 32, and described hollow screw 4 passes in the internal layer 22 of glue-line 2 and the exhaust passage 12 that screw 32 is connected to matrix.
Static pressure air-exhaust mold cores such as described oiled-plate method formula, described glue-line 2 is complementary with concave surface 13 inwalls, and glue-line 2 outer surfaces are parallel with concave surface 13 bottom surfaces.
Static pressure air-exhaust mold cores such as described oiled-plate method formula, described outer 21 are provided with blowhole 23.
The nut place of described hollow screw 4 is provided with air admission hole 41, the screw rod place is provided with steam vent 42, the diameter of described air admission hole is communicated with the gas extraction system of forming static pressure air-exhaust mold cores such as oiled-plate method formula less than the diameter of venthole 42 successively by blowhole 23, air admission hole 41, steam vent 42 and exhaust passage 12.
Described oiled-plate method 3 is parallel with concave surface 13 bottom surfaces, and a plurality of hydraulic pressure hole 31 of oiled-plate method 3 interconnects, and hydraulic pressure hole 31 is communicated with the hydraulic system of the static pressure air-exhaust mold cores such as oil inlet passage 11 composition oiled-plate method formulas of matrix 1.
When making core rod, carry out matrix and oiled-plate method earlier, be coated with in the one side of oiled-plate method and oil, fixedly oiled-plate method is put into the hollow screw again in the appropriate location of matrix.Inject liquid glue then.Wait just becomes glue-line after with regard to liquid gelling admittedly.Because be not have oiling just and the internal layer of glue-line sticks together below the oiled-plate method, be coated with oil above the oiled-plate method, outer part with the oiled-plate method contact just can be separated, and isolation hollow screw and oiled-plate method prevent leakage of oil.
During the work of oiled-plate method formula isostatic mold core, in oil inlet passage, inject hydraulic oil.Hydraulic oil flow through oil inlet passage, oil-in, oil-feed hole, under the pressure of hydraulic oil, when adding hydraulic oil, oil flows between oiled-plate method and skin. and oiled-plate method similarly is the wiring board of oil, its that outside part of glue-line, namely outer, outwards distortion, mobile, press ceramic will be carried out in a plurality of hydraulic pressure hole on its that outside part of glue-line.Because hydraulic oil is to be added between oiled-plate method and its that outside part of glue-line, whole glue-line forms oily bag state, oil is not fully with the matrix contact, so it does not exist with matrix and separates possibility, air in the adobe powder is discharged simultaneously from adobe four limits and gas extraction system, can eliminate adobe fully because of the lamination problem of the bad generation of exhaust, evacuation time and the exhaust number of times handed over when shortening pressing unfired brick are arranged, thereby improve single machine yield.Because characteristics such as the diameter of air admission hole reaches exhaust and do not leak powder, do not stop up, do not need to pacify gas blow pipe less than the diameter of venthole, and is easy to maintenance.
It should be noted that at last: obviously, above-described embodiment only is for example of the present invention clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And the apparent variation of being amplified out thus or change still are among protection scope of the present invention.
