Abstract
The utility model pertains to a forming die, and particularly relates to a forming die used for forming ultra-fine and ultrahigh-pressure powder into matrixes. The powder forming die is characterized in that the powder forming die mainly comprises a pressing rod, a die casing, an O-shaped seal ring, a die base, a pressing sheet A, a vacuum cavity, a pressing sheet B and a vacuum nozzle, wherein the vacuum nozzle is fixed on the die casing by static fit and communicated with a vacuum pump; the O-shaped seal ring is sheathed on the die base; the die casing is arranged above the die base, thus forming the vacuum cavity; and the die pressing sheet B, the die pressing sheet A and the pressing rod are arranged and fixed in the vacuum cavity in sequence. Compared with the prior art, the powder forming die is characterized by simple structure and easy operation. A method for pressing the matrixes is formed, and the deficiencies of crinkling, cracking, edge breaking and the like of the matrixes are effectively overcome.
Description
Technical field
The utility model belongs to a kind of mould, particularly is used for powder compacting ultra-fine, super-pressure and forms the mould of matrix.
Background technology
Existing powder moulding mold is extrusion forming under the normality atmospheric pressure, according to differences such as the granularity of powder, surface tension, selects different mould, pressure.Special powder is owing to have the existence of air drag and can not form matrix, or the matrix that forms have wrinkling, ftracture, collapse defective such as limit, can not form the matrix of needs with existing powder moulding mold.
The utility model content
The purpose of this utility model provides a kind of vacuum cavity mould, makes powder at the vacuum state compacted under, guarantees that powder does not overflow, and forms through external force pressurization back and touches sheet.
Above-mentioned purpose is to obtain by the following technical programs:
Powder moulding mold is characterized in that, mainly comprises depression bar, the mould cover, and the O RunddichtringO, at the bottom of the mould, compressing tablet A, vacuum cavity, compressing tablet B, vacuum nozzle, wherein, vacuum nozzle is fixed on mould by stationary fit and puts, and vacuum nozzle is communicated with vavuum pump; O type snare above mould is mounted at the bottom of the mould, forms vacuum cavity at the bottom of the mould; In vacuum cavity, put into mould compressing tablet B, mould compressing tablet A, depression bar successively, fixing.
Compared with prior art, the utlity model has simple structure, maneuverable characteristics.Form a kind of method of suppressing matrix, and effectively overcome matrix have wrinkling, ftracture, collapse defectives such as limit.
Description of drawings
Fig. 1 is the utility model generalized section, wherein, 1 depression bar, 2 mould covers, the 3O RunddichtringO, at the bottom of 4 moulds, 5 compressing tablet A, 6 vacuum cavities, 7 compressing tablet B, 8 vacuum nozzles, 9 vavuum pumps.
The specific embodiment
Below with drawings and Examples explanation the utility model.
As shown in Figure 1, powder moulding mold mainly comprises depression bar 1, mould cover 2, O RunddichtringO 3, at the bottom of the mould 4, compressing tablet A 5, vacuum cavity 6, compressing tablet B 7, vacuum nozzle 8, vavuum pump 9, wherein, vacuum nozzle 8 is fixed on the mould cover 2 by stationary fit, and vacuum nozzle 8 is communicated with vavuum pump 9; O type circle 3 is enclosed within the bottom of the mould on 4, and mould cover 2 is placed at the bottom of the mould above 4, forms vacuum cavity 6; In vacuum cavity 6, put into mould compressing tablet B7, (pack into and prepare powder for molding), mould compressing tablet A 5, depression bar 1 successively, fixing.
During use, open vavuum pump, being forced into needs pressure, pressurize, and mould is moved back in release, takes out the moulding matrix.
When powder is in cavity body of mould, open vavuum pump.O RunddichtringO on the mold bottom stops extraneous air to enter at this moment, and gas can only suck from cavity body of mould is inner, the compressing tablet A of cavity body of mould inside, compressing tablet B guarantee that powder does not overflow but with the air sucking-off in the cavity, form vacuum and change the surface tension of powder.External force is acted on the mold rods, make cavity form pressure, reach powder compacting.This kind structure can solve the problem of superfines moulding matrix.
