Abstract
A kind of moulding machine crossbeam with pressing device for sand forming of almost equal unit pressure, in this crossbeam, be provided with one hardly compressible material make, its hardness is less than the high resiliency plate of 40 Durometer A hardness.
Description
The present invention relates to a kind of pressing device for sand forming with almost equal unit pressure.
Fixation clip in the known simple moulding machine mostly can not reach satisfied result, because produce overcompression at the boss of module, and can not obtain enough pressure in other zones.
Known some so-called double punching machines in addition, this machine is made of a plurality of hydraulic cylinders arranged side by side mutually, and these hydraulic cylinders piston rod of operation downwards are provided with the compacting base, and this compacting base covers whole profile jointly.
This method is very expensive and easily wear and tear, and also owing to will using a plurality of fixation clips, and these pressing plates can not reduce certain size because of structural reason, and the while can not guarantee uniform compression, particularly edge region.
Task of the present invention is to overcome aforementioned weak point.
The technical measures that realize above-mentioned task are, the high resiliency plate of that made by compressible material hardly, its hardness less than 40 Durometer A hardness is set in the moulding machine crossbeam.
By means of accompanying drawing a most preferred embodiment of the present invention is further elaborated.
Fig. 1 is shown with a pressure setting of the present invention.
Dispose one above together with the sandbox 2 of institute's suit and back-up sand frame 3 at model equipment 1 and can make the moulding machine crossbeam 5 that moves both vertically by hydraulic cylinder 4.
On moulding machine crossbeam 5, be fixed with a slab of making by elastomeric incompressible material 6, can in material 6, be provided with air chamber 10 when needing.
When moulding machine crossbeam 5 pressurizes on the molding sand by acting on of cylinder barrel 4, elastic plate 6 just adapts to the differently contoured different compressibilities that cause sand because of model 1, make on the sand face of each square centimeter, remove outside the edge guard 9, all produce one and be close to uniform unit pressure.
Because elastic plate 6 is made by compressible material (as: rubber, silicones etc.) hardly, and this plate " is recessed into " at the boss of module, and in the flat part of module " protrusion ".
In some cases, particularly when the model of compacting projection especially, elastic plate is provided with some air chambers at these model areas, to guarantee local compressibility.
In another kind of common structure form, not that pressing plate 5 is pressurizeed to sand 7 by a cylinder 4, but molding box 2, model equipment 1, back-up sand frame 3 and sand 7 are pressurizeed to fixed configurations pressing plate in the above by the compacting cylinder of underlying.
Claims (4)
