Description
Technical field
The utility model relates to medical material processing, is specifically related to the former of zirconium oxide porcelain block used for stomatological repair.
Background technology
The common main application of zirconium oxide porcelain block is exactly for fixed denture reparation use, and usual profile is disc.The conventional production practices of current zirconium oxide porcelain block is: add in mould by zirconia powder, and profile powder being shaped to want in advance by hydraulic pressure compacting, this process can referred to as pre-molding.Then by isostatic pressed, final external form finishing is carried out to product, obtain the shape of product wanted.Then sintering obtains product.In powder pre-compaction process, normally a cylindrical mold, inserts powder, then exerts pressure to powder with piston-like pressure head.
But such structure exists a lot of drawback: if the endoporus of piston-like pressure head and cylindrical mold is identical, then the gas in mould is not easy to discharge, and equipment runs and has some setbacks; Powder is also easy to be sprayed from pressure head edge with air-flow, causes waste.If indenter size is less than mould endoporus, then edge material compacting can be caused irregular, leave chimb.And such pressing process cannot ensure that powder is evenly distributed, and the powder added natively presents rugged state usually, compressing base substrate various places inside density unevenness.Even there is the few material in local, occur the situation lacking few angle, limit.Cause formed product defective, waste processing cost.
Summary of the invention
The purpose of this utility model is to provide a kind of zirconium oxide porcelain block pre-molding device used for stomatological repair, and the porcelain block profile occurred in solution zirconium oxide porcelain block pre-molding is irregular, the unequal problem of internal density.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of zirconium oxide porcelain block pre-molding device used for stomatological repair, and comprise the cylindrical shape mould of lower end closed, mould is fixed on base plate; Arrange above mould in the push-down head of inverted T-shaped, push-down head upper end connects the connecting plate being convenient to connecting fluid press mechanism, and push-down head is identical and coaxially arranged with mould shape; Also comprise the pressing body of an inverted T-shaped, flatten body identical with push-down head profile, the size flattening body lower end is less than push-down head lower end size; Pressing body is enough put into or shifts out mould by the stroke that presses down of push-down head.
Preferably, described mould lower end is connected with base plate by thinner collar, and base plate and collar junction are arranged leads round transition.The powder conveniently sprayed and spill is collected and is swept.
When device of the present utility model uses, push-down head is connected with hydraulic mechanism by installing plate.First powder is put into mould to shakeout, then operator grips and flattens body top, moves up and down to flatten body and gently pressed downwards by powder, and repeated several times back and forth; The orientation at every turn pressed down can change, evenly to flatten, guarantees that plane gone up before compaction by powder smooth, and is not easy to spray under push-down head moves the airflow function of formation.Then primer fluid press mechanism push-down head carries out large pressure pre-molding to powder.The utility model adds the instrument of manually stand pressure, can avoid the problem that material itself is uneven, also reduce the possibility of material spray; Ensure can not stay chimb in pre-compaction process.The porcelain block neat appearance of pre-molding, even density, yield rate is high, reliably up-to-standard.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the pre-molding device of zirconium oxide porcelain block used for stomatological repair, comprise the cylindrical shape mould 2 of lower end closed, mould 2 is fixed on base plate 21, is convenient to place steadily.Arrange the push-down head 3 in inverted T-shaped above mould 2, push-down head 3 upper end connecting plate 4, connecting plate 4 is connected for same hydraulic mechanism 6.Push-down head 3 and mould 2 shape are coincide and coaxially arranged, and the namely push-down head 3 that coincide of shape is herein that lower end 31 appearance and size is identical with mould 2 hole size; In lower large little ladder shaft-like, namely aforesaid inverted T-shaped.Like this under the driving of hydraulic mechanism 6, push-down head 3 can move up and down, and just the powder in mould 2 is compacted into zirconium oxide porcelain compact body 1 in folding process.
The utility model also comprises the pressing body 5 of an inverted T-shaped, flattens body 5 identical with push-down head 3 profile, is also ladder shaft-like or is called inverted T-shaped.The size flattening the lower end 51 of body 5 is less than lower end 31 size of push-down head 3; Avoid like this flattening in body 5 folding process and cause larger air-flow, allow loose powder spray.Mould 2 is put into or shifted out to pressing body 5 enough by the stroke that presses down of push-down head 3, ensures that flattening body 5 can shift out and put into mould 2.Namely as shown in Figure 1, the spacing after push-down head 3 return between itself and mould 2 enough flattens body 5 and puts into mould 2 or take out.
During use, first powder is put into mould 2 and shakeout, operator grips and flattens body 5 top, moves up and down to flatten body 5 and gently pressed downwards by powder, and repeated several times back and forth, evenly to flatten.Guarantee that powder suppresses front upper plane at push-down head 3 smooth, under push-down head downward 3 moves the air-flow of formation, powder can not spray.Restart hydraulic mechanism 6 push-down head 3 pairs of powders and carry out large pressure pre-molding.Can avoid so just directly suppressing with push-down head 3 when powder injustice, cause the problems such as porcelain block profile irregularity, Density inhomogeneity.Yield rate is high, improves working (machining) efficiency generally, reduces processing cost.
Certainly, when reinforced and compacting, a small amount of powder spills or sprays is unavoidable.Therefore mould 2 lower end of the present utility model is connected with base plate 21 by thinner collar 22, and base plate 21 and collar 22 junction are arranged leads circle 23 transition.The powder spilt like this can not directly be deposited in mould root, so easy cleaning powder, recycles.
