Abstract
The utility model discloses a sealing rubber cover of forming and filling a cold isostatic pressing machine wet bag flexible die, and a rubber plug (3) at the die orifice of a flexible die (2) is provided with a rubber cover (4). Because the rubber cover is arranged at the die orifice of the flexible die, the utility model solves the pollution problem of oil impregnation of the die orifice of the flexible die through the matching use of the rubber cover and the rubber plug, so as to cause oil not to be stuck on the outer wall of the die orifice when being used again. Molybdenum billet produced by the method removes the contact chance of molybdenum powder and billet and the oil during the production process, ensures that the chemical composition of the billet reaches the mark without being polluted, and ensures the physical and the chemical properties. The utility model has simple tool and operation, and ensures the product quality without adding new equipment.
Description
Technical field
The utility model relates to the anti-immersion oil sealing tech field of the wet bag of cold isostatic press soft mould dress mould, what relate generally to is the wet bag of a kind of cold isostatic press soft mould dress mould sealing compound lid.
Background technology
The compacting of the wet bag of cold isostatic press soft mode is that powder is packed in the soft mode, with plug jam-pack soft mode mouth, in the high-pressure bottle of packing into then, makes mould bag dip stand the highly pressurised liquid compacting that high-pressure pump injects in liquid pressure medium.
The large-scale molybdenum of compacting, tungsten product all are to adopt the compression moulding of wet bag soft mode in the powder metallurgy industry at present.Traditional wet bag soft mould is that powder material 1 is packed in the soft mode 2, and with plug 3 jam-pack seals (as shown in Figure 1), in the high-pressure bottle of packing into then, dip stands the highly pressurised liquid compacting that high-pressure pump injects in liquid pressure medium.Because die bearing was steeped by oil immersion in when compacting, promptly use cotton yarn to wipe and also be difficult to clean, the high temperature blank the during demoulding (because of the pressurized temperature is elevated to about 40 ℃) can make the oil stain on the material base just become dry moment, whether is difficult to find immersion oil when reusing.Will be when the soft mode mouth that has greasy dirt is like this adorned the powder material once more by oil pollution, the result makes and has carried greasy dirt in the molybdenum powder secretly.No matter so as long as be that pressed compact piece or molybdenum powder have contacted the mineral greasy dirt, in sintering process be so can 100% greasy dirt is discharged, still having impurity such as part carbon, nitrogen, lead, arsenic in the material base residues in the sintered compact, reduce high-purity molybdenum bar quality, be difficult to satisfy the requirement of wire drawing and high-quality molybdenum deep processing material.
Summary of the invention
The purpose of this utility model is to propose the wet bag of a kind of cold isostatic press soft mould dress mould sealing compound lid.Solve the pollution problem of soft mode die orifice immersion oil, the die orifice position was not polluted by immersion oil when soft mode was reused, and guaranteed the quality of material base.
The technical scheme that realization above-mentioned purpose of the present utility model is taked is: its plug position at the soft mode die orifice is provided with Jiao Gai.
The utility model is used by Jiao Gai and plug owing to be provided with Jiao Gai at soft mode die orifice position, has solved the pollution problem of soft mode die orifice immersion oil, the not sticking oil of die orifice inside and outside wall when it is reused.The molybdenum blank of being produced has in this way been stopped the touch opportunity of molybdenum powder and blank and greasy dirt in process of production, has guaranteed that the material base chemical composition is up to standard, and is not contaminated, and then guarantees its physics and chemical property.The instrument of its use is simple, and is simple to operate, and it is guaranteed need not increase new equipment and product quality.
Description of drawings
Fig. 1 is the structural representation of traditional moulding soft mode.
Fig. 2 is the utility model structural representation.
Among the figure: 1, powder material, 2, soft mode, 3, plug, 4, Jiao Gai.
The specific embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in Figure 2, it is on the architecture basics of the wet bag of existing cold isostatic press soft mode 2, and the die orifice position that plug 3 is housed at soft mode 2 is provided with glue lid 4.Choose soft mode 2 during use earlier, plug 3 jam-pack die orifices are used in the powder material that scale is the good 1 minute soft mode tamping of packing into for several times then, reserve size (diameter and length), and tighten with wire, utilize plank, wooden stick by hand method pat to rub and carry out integer.Integer is opened wire after finishing, stopper is taken out, the strickling of top molybdenum powder, tamping, use probe to insert empty mould with scraper again, utilize probe both sides interstitial row to go out air greater than empty mould length Φ 1.5-3mm, put into plug (plug length is not less than sky mould length) once more, firmly compacting makes stopper and molybdenum powder contact-making surface tight, extracts probe out, pricks twice (cross distribution in the stopper bottom with wire again, symmetry is firmly), plug and soft mode are fastened; Wear after the compacting of soft mode oral area with wire with glue lid 4 again Jiao Gai and soft mode and plug are tightened.Hang in compacting in the machine, after suppressing, hang out and slough (soft mode oral area inside and outside wall and plug do not have greasy dirt) behind the Jiao Gai, carry out the demoulding.The molybdenum blank of being produced has in this way been stopped the touch opportunity of molybdenum powder and blank and greasy dirt in process of production, has guaranteed that the material base chemical composition is up to standard, and is not contaminated, and then guarantees its physics and chemical property.The not sticking oil of die orifice inside and outside wall when soft mode reuses.
Claims (1)
1, the wet bag of a kind of cold isostatic press soft mould dress mould sealing compound lid comprises soft mode (2), plug (3), and it is characterized in that: the die orifice position that plug (3) is housed at described soft mode (2) is provided with Jiao Gai (4).
