Abstract
The utility model provides a tungsten powder metallurgy product forming die, includes the steel mould, lay rubber slab and the clamp plate of tiling on the rubber slab at steel mould opening position, wherein, through bolted connection between steel mould, rubber slab and the clamp plate three, and between steel mould and the bolt, all be equipped with sealed the pad between steel mould and the rubber slab, the position of being connected that lies in the inboard steel mould upper end of bolt and rubber slab is equipped with the semicircular recess, and the embedded rubber seal that is equipped with of recess, the clamp plate on be equipped with the filling hole that is used for to pouring into the cold isostatic pressing medium between clamp plate and the rubber slab 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 work piece.
Description
Technical field
This utility model relates to technical field of metal, is specifically related to a kind of tungsten powder metallurgy product mould.
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 uses mechanical press or hydraulic press Direct Rolling, be unsuitable for suppressing bigger and longer goods.
Utility model content
The purpose of this utility model is to provide a kind of tungsten powder metallurgy product mould, and to be solved technical problem is that overcomes the problem that employing punching block in prior art is poorly sealed and is difficult to produce massive article.
The technical scheme that this utility model is used for achieving the above object is: a kind of tungsten powder metallurgy product mould, including punching block, the rubber slab being laid on punching block opening and the pressing plate being laid on rubber slab, wherein, punching block, it is bolted between rubber slab and pressing plate three, and between punching block and bolt, sealing gasket it is equipped with between punching block and rubber slab, the connecting portion being positioned at the punching block upper end inside bolt and rubber slab is provided with semicircular groove, rubber seal it is embedded with in groove, described pressing plate is provided with for the hand-hole injecting isostatic cool pressing medium between pressing plate and rubber slab.
Further, the interior knuckle of punching block upper end is rounding.
Preferably, the thickness of described rubber slab is 5 ~ 10mm, and the thickness of pressing plate is 10 ~ 15mm, and the aperture of hand-hole is 10mm.
Beneficial effect: this utility model utilizes punching block and rubber slab combination to carry out cold isostatic compaction, and by the hand-hole of setting on pressing plate at the uniform velocity injecting isostatic cool pressing medium between pressing plate and rubber slab, the workpiece 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 workpiece.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.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Reference: 1, punching block, 2, rubber slab, 3, pressing plate, 4, bolt, 5, groove, 6, hand-hole.
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 powder metallurgy product mould, as shown in Figure 1, including punching block 1, the rubber slab 2 being laid on punching block 1 opening and the pressing plate 3 being laid on rubber slab 2, wherein, punching block 1, connected by bolt 4 between rubber slab 2 and pressing plate 3 three, and between punching block 1 and bolt 4, it is equipped with sealing gasket between punching block 1 and rubber slab 2, the connecting portion being positioned at punching block 1 upper end inside bolt 4 and rubber slab 2 is provided with semicircular groove 5, it is embedded with rubber seal in groove 5, described pressing plate 3 is provided with for the hand-hole 6 injecting isostatic cool pressing medium between pressing plate 3 and rubber slab 2, wherein, the interior knuckle of punching block 1 upper end is rounding.Preferably, the Outside Dimensions of rubber slab 2 and pressing plate 3 is consistent with the Outside Dimensions of punching block 1；Preferably, pressing plate 3 is metal platen.
Preferably, the thickness of rubber slab 2 is 5 ~ 10mm, and the thickness of pressing plate 3 is 10 ~ 15mm, and the aperture of hand-hole 6 is 10mm.
Punching block 1 of the present utility model and pressing plate 3 can be reused, and reduce cost；And, the outer wall of goods formed thereby is smooth, and flatness is good.
