Abstract
The utility model provides a tungsten crucible shaping special mould, including the steel core, rubber sleeve and fixed cover, the shaping die cavity of crucible has been formed between steel core outer wall and the rubber sleeve inner wall, the steel core is the perpendicular protruding type body structure that constitutes of connecting of second pellet by the first pellet of level setting and vertical setting, the rubber sleeve is constituteed at the rubber end cover of packing element upper end by being columniform packing element and sealing connection, the packing element cover is peripheral at the steel core, the lower part of fixed cover, pass through the screw connection between packing element's lower part and the first pellet three, and between fixed cover and the packing element, all be equipped with the sealing washer between packing element and the first pellet, fixed sheatheeing in is equipped with the filling hole that is used for to pouring into the cold isostatic pressing medium between fixed cover and the rubber sleeve into. Sealed problem has been solved to this mould, has broken through the limit between steel mould and the cold isostatic pressing, overcomes the defect that traditional cold isostatic pressing pressed compact size precision is poor, not only can reach the requirement of traditional steel mould pressing system product, can also produce large -scale crucible goods.
Description
Technical field
This utility model relates to technical field of metal, is specifically related to a kind of tungsten and molybdenum crucible molding particular manufacturing craft.
Background technology
Material is one of China's four big industries, including high-molecular organic material, composite, metal material and Inorganic Non-metallic Materials.The one that PM technique manufactures as metal material, jointly developing with other manufacture method with its irreplaceable unique advantage, powder metallurgy has relative to for other metallurgical technology: low cost, allowance are few, raw material availability is high, can produce other methods such as porous material can not produce or the advantage such as the material of very difficult production.Powder metallurgy is to produce metal dust and with non-metal powder compound molding and sintering, metal dust or metal dust are produced the technology of powdered metallurgical material or sintered metal product.
Powder body shaping is the basic working procedure of powder body material preparation technology, and mould is to realize the critical process equipment that powder body material shapes.Powder body manufacturing process includes cold isostatic compaction, and its defect is that rubber mold deviation is big, and is difficult to produce large-scale workpiece, and cost is high, there is poorly sealed problem；And steel mold pressing shapes, it is that metal dust is loaded steel mold cavity, is allowed to shape to powder pressurization by stamping, although deviation is less, but be not suitable for suppressing crucible product.
Utility model content
The purpose of this utility model is to provide a kind of tungsten and molybdenum crucible molding particular manufacturing craft, and to be solved technical problem is that overcomes the problem using punching block poorly sealed in prior art.
nullThe technical scheme that this utility model is used for achieving the above object is: a kind of tungsten and molybdenum crucible molding particular manufacturing craft，Including steel core、Seal closure is at the rubber sleeve outside steel core and is set in the fixed cover outside rubber tube，Wherein，The forming recess of crucible is defined between steel core outer wall and rubber sleeve inwall，Described steel core is by the horizontally disposed first pellet convex integrative-structure that connect and compose vertical with the second pellet being vertically arranged，Described rubber sleeve is formed with the end cover rubber being sealedly connected on rubber tube upper end by cylindrical rubber tube，It is peripheral that rubber tube covers on steel core，The bottom of fixed cover、It is connected by screw between bottom and the first pellet three of rubber tube，And between fixed cover and rubber tube、It is equipped with sealing ring between rubber tube and the first pellet，Described fixed cover is provided with for the hand-hole injecting isostatic cool pressing medium between fixed cover and rubber sleeve.
Further, the first pellet, the outer knuckle of the second pellet upper end are rounding.
Preferably, the thickness of described rubber tube and end cover rubber is 5 ~ 10mm, and the thickness of fixed cover is 10 ~ 15mm, and the aperture of hand-hole is 10mm.
Beneficial effect: this utility model utilizes steel core and rubber sleeve to combine, cold isostatic compaction mould as crucible, by the hand-hole of setting on fixed cover at the uniform velocity injecting isostatic cool pressing medium between fixed cover and rubber sleeve, the crucible flatness made is preferable, and little to the abrasive action of mould；And, this mould solves sealing problem, breaches the boundary between punching block and cold isostatic compaction, overcomes the defect of traditional cold isostatic pressed pressed compact poor dimensional precision, can not only reach the requirement of tradition steel mold pressing product, it is also possible to produce large-scale crucible product.Wherein, the interior knuckle of punching block upper end is rounding, prevents invar to be molded as the abrasion of rubber slab, improves recycling rate of waterused.

Detailed description of the invention
Below in conjunction with specific embodiment, a kind of tungsten powder metallurgy product mould of the present utility model is described further, so that those skilled in the art can be better understood from this utility model and can be practiced.
A kind of tungsten and molybdenum crucible molding particular manufacturing craft, as shown in Figure 1, including steel core, seal closure is at the rubber sleeve outside steel core and is set in the fixed cover 8 outside rubber tube, wherein, the forming recess 5 of crucible is defined between steel core outer wall and rubber sleeve inwall, described steel core is the convex integrative-structure vertically connected and composed with the second pellet 2 being vertically arranged by horizontally disposed first pellet 1, and the outer knuckle of first pellet the 1, second pellet 2 upper end is rounding.Described rubber sleeve is formed by cylindrical rubber tube 3 and the end cover rubber 4 being sealedly connected on rubber tube 3 upper end, the thickness of rubber tube 3 and end cover rubber 4 is 5 ~ 10mm, it is peripheral that rubber tube 3 covers on steel core, the bottom of fixed cover 8, connected by screw 6 between bottom and first pellet 1 three of rubber tube 3, and between fixed cover 8 and rubber tube 3, it is equipped with sealing ring between rubber tube 3 and the first pellet 1, described fixed cover 8 is provided with for the hand-hole 9 injecting isostatic cool pressing medium between fixed cover 8 and rubber sleeve, the thickness of fixed cover 8 is 10 ~ 15mm, the aperture of hand-hole 9 is 10mm.
When actually used, the first pellet 1 and the second pellet 2 can be set to Split type structure, be connected with each other by screw therebetween, or directly weld setting.This utility model uses steel core, is unlikely to deform, can Reusability；And, good sealing effect between steel core and rubber sleeve, the yield rate of the crucible of compacting is high, inner wall smooth.
