Technical field
This utility model belongs to technical field of mold, especially relates to a kind of tungsten crucible production mould.
Background technology
Tungsten crucible, English name: Tungsten Crucibles is one of tungsten goods, is broadly divided into sinter molding,
Punch forming, spun type, utilize tungsten bar turnery processing molding, welding fabrication etc. is multiple.Tungsten crucible can be below 2600 degree
Vacuum inert gas uses.The fusing point boiling point of tungsten is high, and elevated temperature strength is good, wear-resistant corrosion-resistant, and pyroconductivity is big, thermal coefficient of expansion
Little, quenching degree is good, has benefited from the most excellent characteristic, and tungsten crucible is widely used in sapphire crystal growth, rare-earth smelting, stone
English glass, the industry such as electronics spraying.
Use rubber mold, owing to rubber mold has elasticity, therefore filling powder when, be likely to result in and add powder not
All, to such an extent as to after compacting sintering molding, crucible wall thickness is inconsistent, increases the difficulty of machining, also improves manufacturing cost.
Although such scheme to some extent solves the deficiencies in the prior art, but it is regular to be a lack of a kind of outward appearance, uniform wall thickness
Tungsten crucible production mould.
Utility model content
The purpose of this utility model is for the problems referred to above, it is provided that a kind of outward appearance is regular, and the tungsten crucible of uniform wall thickness produces
Use mould.
For reaching above-mentioned purpose, this utility model have employed following technical proposal: a kind of tungsten crucible of the present utility model is raw
Product mould, described tungsten crucible production mould include core, the soft mode being enclosed within outside core, be arranged on soft mode top lid and
Described soft mode is outside equipped with the outer steel sleeve limiting the outside deformation of described soft mode, and described outer steel sleeve is inner hollow and up/down perforation
Cylindrical body；The cavity accommodating tungsten powder is formed between described core and mantle；Described core includes mold core body and is located at this core rod
The die station of main body bottom, the bottom of described die station is provided with positive stop lug boss, and the bottom of described outer steel sleeve fits with positive stop lug boss；
Described soft mode is cylindrical containing cavity, and the outer ring surface of described lid is provided with the annular groove being arranged concentrically with containing cavity,
Being provided with O-ring seal in described annular groove, described O-ring seal is formed to seal with containing cavity and coordinates.
Further, described positive stop lug boss is 3-10mm.
Further, the shape of described core, soft mode and lid is cylindrical shape.
Further, the thickness of described soft mode is 3-10mm, and the thickness of described outer steel sleeve is 3-10mm.
Further, the material of described soft mode is rubber.
Further, the material of described core is rustless steel.
Further, described O-ring seal is provided with breach, in described breach, is provided with slide block, described breach two
Side is additionally provided with the block preventing described slide block from skidding off, and described O-ring seal outer ring is provided with soft annulus.
Further, described O-ring seal being additionally provided with passage, described passage end connects described breach, described logical
The position in road to the distance of the block outside described breach less than the thickness of described slide block.
Beneficial effect: this utility model simple in construction, reasonable in design, and the outer steel sleeve parcel whole cylinder of soft mode, work
During play spacing moulding effect, pressed compact entirety outer wall is smooth, and outward appearance is regular, uniform wall thickness, is greatly reduced blank and adds spare time
Amount, improves production efficiency.Outer steel sleeve prevents the correction operation of bias during eliminating filling tungsten powder, saved the time, fall
Low operation easier.
Compared with prior art, this utility model has the advantage that
(1) this utility model is provided with outer steel sleeve, and this outer steel sleeve is set in outside soft mode, is used for limiting soft mode generation shape
Become so that this utility model can utilize outer steel sleeve to limit soft mode during loading tungsten powder and expand outwardly deformation, makes tungsten powder
It is uniformly distributed in soft mode, thus after this utility model process finishing, is easy to the demoulding, and the tungsten crucible blank chi produced
Very little uniformly, inwall bright and clean, without chipping, flawless, following process requirement, production efficiency height can be reached.
(2) by ring flange, soft mode is fixed, reached the effect of the original employing spacing soft mode of metal die station；Sealing member
Reach sealing effectiveness, solve conventional seals fork clip due to the difficulty of pressure difference handling, this black box phase inside and outside working cavity
The most open to soft mode, reduce manipulation strength and difficulty, improve production efficiency.
