Abstract
The utility model relates to a zirconia porcelain block production powder recovery unit for mouth rehabilitation, its purpose avoids the press forming in -process face powder phenomenon to appear, reduces the waste, and protective apparatus and personnel are healthy. The powder recovery unit include: cylinder forming die, forming die fix on the bottom plate, the forming die top sets up the lower pressure head that is the shape of falling T, pushes down overhead end and connects the connecting plate of being convenient for connect hydraulic pressure mechanism, and lower pressure head coincide and coaxial arranging with the forming die shape, collecting hopper is down connected to the last port of forming die, pushes down overhead portion and connects collecting hopper down, going up collecting hopper and collecting hopper down, to be the opening relative tubaeform, and at least one is made by elastic material among both. The utility model discloses an useful technological effect is: it can effectively avoid the face powder phenomenon in the pressing process.
Description
Technical field
The utility model relates to medical material processing, is specifically related to appurtenance compressing in zirconium oxide porcelain block used for stomatological repair processing.
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 nanoscale zirconia powder, profile powder being shaped to want in advance by hydraulic pressure compacting.Then by isostatic pressed, final external form finishing is carried out to product, obtain the shape of product wanted.Then through high temperature sintering, machining, serigraphy be packaged to be can product sold.
In pressing process, the moment that press ram contacts with powder, there is comparatively air flow to produce, usually there will be face powder phenomenon; Namely mold periphery very large regions to waft nano zirconium oxide powder.The generation of this phenomenon not only causes the significant wastage of raw material, increases production cost; Also pollute the environment, be unfavorable for career safety & health, affect operator healthy; Simultaneously also contaminated equipment, causes equipment lubrication system to go wrong, affects service life.
Utility model content
The purpose of this utility model is to provide a kind of zirconium oxide porcelain block used for stomatological repair and produces powder reclaiming device, to reduce the waste of zirconia powder.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of zirconium oxide porcelain block used for stomatological repair produces powder reclaiming device, and comprise cylindrical shape mould, 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; Described mould upper port connects lower aggregate bin, and push-down head top connects upper aggregate bin; Upper aggregate bin and lower aggregate bin are relative tubaeform of opening, and in both, at least one is made up of elastomeric material.
Preferably, described upper aggregate bin has been evenly arranged circular hole, and circular hole is closed by elastic film, plays the effect of air pressure during buffering work.
Preferably, described upper aggregate bin, lower aggregate bin are made by silica gel; The bore of upper aggregate bin is less than or equal to the bore of lower aggregate bin.
Powder reclaiming device described in the utility model, during use, upper aggregate bin is synchronized with the movement along with push-down head, and when push-down head compresses nano-zirconia powder and lower aggregate bin edge paste hold together closed; When making compacting, powder local presents the state of sealing, can stop to occur that face powder overflows the phenomenon of phenomenon, thus also serving the effect economizing in raw materials, reduce costs, also serving purification working environment, the effect of protection staff and production equipment.And powder is concentrated in lower aggregate bin, fall into mould interior for next time, be convenient to produce.
Accompanying drawing explanation
Fig. 1 is the structural representation of upper and lower aggregate bin and pre-molding device;
Fig. 2 is the structural representation in this retracting device work.
Detailed description of the invention
As shown in Figure 1, a kind of zirconium oxide porcelain block used for stomatological repair produces powder reclaiming device, and it comprises: cylindrical shape mould 2, and mould 2 is fixed on base plate.Arrange the push-down head 3 in inverted T-shaped above mould 2, push-down head 3 upper end connects the connecting plate 4 being convenient to connecting fluid press mechanism 6.Push-down head 3 is identical and coaxially arranged with mould 2 shape; Wherein push-down head 3 can sweeping action under the driving of hydraulic mechanism 6, and the powder 8 in mould 2 is pressed into porcelain compact body.Described mould 2 upper port connects lower aggregate bin 1, and push-down head 3 top connects lower aggregate bin 1; Tubaeform relative in opening of upper aggregate bin 5 and lower aggregate bin 1, upper and lower aggregate bin 1 forms a closed space, in both, at least one is made up of elastomeric material, the T-shaped push-down head 3 of such guarantee is in telescopic process, upper aggregate bin 5 or lower aggregate bin 1 are followed flexible simultaneously, and close as closed state, place powder ejection under push-down head 3 impacts.
Better improvement is, described upper aggregate bin 5 has been evenly arranged circular hole, and circular hole is closed by elastic film 7.Like this in pressing process, time two aggregate bins just contact, elastic film 7 meeting rising under internal gas pressure, thus cushioning effect is played to air pressure inside, avoid from two aggregate bin 1,5 edge pressure release and material sprays.More preferred scheme is, described upper aggregate bin 5, lower aggregate bin 1 are made by silica gel, and the bore of upper aggregate bin 5 is less than or equal to the bore of lower aggregate bin 1.So that powder is collected in lower aggregate bin 1, can not be able to drop to outside device on the one hand; The wearing and tearing of rigid contact can also be avoided, improve the life-span of material-gathering device to greatest extent.
Shown in composition graphs 1,2, operation principle of the present utility model is: upper aggregate bin 5, under the drive of hydraulic mechanism 6 active force, is followed inverted T-shaped push-down head 3 and pressed down.When push-down head 3 lower end extruding powder 8, upper aggregate bin 5 starts to contact with lower aggregate bin 1 edge, and it is closed to be progressively adjacent to formation, and elastic film 7 rising plays the effect of compensator or trimmer pressure.And the particulate dust that push-down head 3 impact is got up remains in the closed area between two aggregate bins 1,5, and deposit gradually, drop in lower aggregate bin 1.Pause a moment, push-down head 3 bounces back, and then repeats to press down, retraction process.Until by pre-stamped for powder 8 shaping.Whole process stops the spilling of porcelain powder completely, reaches saving material cost, the effect of purification production environment.
