Abstract
The utility model discloses a mold for manufacturing a tungsten crucible in a pressed mode. The mold comprises an inner metal mold body, a soft mold outer shell, a soft plug and a fastening part, wherein the inner metal mold body is sleeved with the soft mold outer shell, the soft plug is arranged on the top of the soft mold outer shell, and the fastening part is used for fastening the top and the bottom of the soft mold outer shell. The inner metal mold body is a rotating body which is integrally formed with the bottom open, and the rotating body comprises a metal mold core with a reverse-U-shaped longitudinal section and a metal mold table which is arranged at the opening of the bottom. When the mold for manufacturing the tungsten crucible in the pressed mode is adopted, the technical problem of the defects caused by deformation of a soft rubber ring under high pressure is solved, the casting yield is improved, the end product quality of the tungsten crucible is improved, and the production cost is reduced; on the other hand, the original working procedure that the soft rubber ring is fixed on the metal mold core in an interference fitting mode is omitted due to the fact that the metal mold table is fixedly arranged on the metal mold core, and therefore production efficiency is improved.

Technical field
The utility model relates to a kind of mould for making tungsten crucible and using, particularly the mould used of a kind of novel compacting tungsten crucible.
Background technology
Tungsten crucible is one of tungsten goods, and it is widely used in rare-earth smelting, quartz glass, electronics spraying, the industries such as crystal growth.
Existing tungsten crucible drawing method is, gauge size according to the tungsten crucible that will produce, select suitable mould (as shown in Figure 1), the mode that first adopts interference to connect on the soft ring of rubber is fixed on the bottom side position of metal core rod, again with the soft mode casing on the soft ring of rubber, then with iron wire, bind the soft mode outer casing bottom, add tungsten powder, cork is filled in the top of soft mode shell, then with iron wire, bound the soft mode cover top portion.Whole mould is placed in the pressurization cylinder body of cold isostatic press the compacting of pressurizeing, takes out finally the blank tungsten crucible from mould, complete whole pressing process.
But due to when pressurizeing compacting, the pressure of the pressurization cylinder interior of cold isostatic press is very large, and the soft ring of rubber under suppressing, can deform, thereby makes the corresponding pot of tungsten crucible interruption-forming wedge-shaped opening, thereby may form waste product, affects casting yield; In addition on the one hand, under suppressing, meeting is compressed due to the soft ring of rubber, and the iron wire that is bundled on soft mode shell bottom side is loosening even to come off thereby can make, and makes the fluid under pressure of pressurization cylinder body infiltrate in mould, and end product quality is caused great impact.
The utility model content
The utility model pin technical problem to be solved is the defect that exists for prior art, the mould that provides a kind of novel compacting tungsten crucible to use, it can effectively solve the defect that the soft ring of above-mentioned rubber is being suppressed lower generation deformation and caused, improve casting yield, improve the tungsten crucible end product quality, thereby reduced production cost, improved production efficiency.
For solving above technical problem, the utility model by the following technical solutions
:The mould that a kind of novel compacting tungsten crucible is used, comprise the metal inner mould body, be enclosed within the soft mode shell of described metal inner mould external body, the encircling part that is arranged on the cork of described soft mode cover top portion and is used for binding described soft mode cover top portion and bottom, the revolving body of the bottom opening that described metal inner mould body is formed in one, described revolving body comprise the metal core rod of inverted U longitudinal section and the metal pattern platform that is arranged on the bottom opening place.
Preferably, described metal pattern platform sidepiece is provided with adjusting hole.
Preferably, the quantity of described adjusting hole is 4, is evenly distributed on the quarter turn position of described metal pattern platform cross section.
Preferably, described metal inner mould body adopts steel.
Preferably, described encircling part is iron wire.
The beneficial effects of the utility model are: adopt the utility model to suppress tungsten crucible, both realized the function of the original soft ring of rubber due to described metal pattern platform, again because itself is that metal material is made, under suppressing, can not be out of shape as the soft ring of rubber, thereby solve suppressing the soft annular technical problem that becomes the defect that causes of lower rubber, improve casting yield, improve the tungsten crucible end product quality, reduced production cost; In addition on the one hand,, because described metal pattern platform is integrated with the metal core rod, saved original " adopting the mode of interference connection to be fixed on the metal core rod on the soft ring of rubber " such operation, thereby improved production efficiency.

The specific embodiment
Existing tungsten crucible drawing method is, gauge size according to the tungsten crucible that will produce, select suitable mould (as shown in Figure 1), the mode that first adopts interference to connect on the soft ring 1 of rubber is fixed on the bottom side position of metal core rod 2, again soft mode shell 3 is enclosed within on the soft ring 1 of rubber, then with iron wire 4, binds soft mode shell 3 bottoms, add tungsten powder 5, cork 6 is filled in the top of soft mode shell 3, then with iron wire 4, bound soft mode shell 3 tops.Whole mould is placed in the pressurization cylinder body of cold isostatic press the compacting of pressurizeing, takes out finally the blank tungsten crucible from mould, complete whole pressing process.
The utility model embodiment: as shown in Figures 2 and 3, the mould that a kind of novel compacting tungsten crucible is used, comprise metal inner mould body 7, be enclosed within the soft mode shell 3 of described metal inner mould external body, be arranged on the cork 6 at described soft mode shell 3 tops and the encircling part that is used for binding described soft mode shell 3 tops and bottom, the revolving body of the bottom opening that described metal inner mould body 7 is formed in one, described revolving body comprise the metal core rod 2 of inverted U longitudinal section and the metal pattern platform 8 that is arranged on the bottom opening place.
Described metal pattern platform 8 sidepieces are provided with adjusting hole 9, after mold integral installs, need, with suspender, it to be winched in the pressurization cylinder body of cold isostatic press the compacting of pressurizeing.When mold integral is placed in suspender, need to guarantee that its position of center line and described suspender position of center line on same position, guarantee that namely mold integral is positioned over the center of suspender, otherwise can cause mold integral to be placed on suspender the time, turn on one's side, cause contingency.Adjusting hole 9 is set on metal pattern platform 8, exactly in order to adjust the position of mold integral in suspender.When there was deviation position, available iron pipe inserted in adjusting hole, pulls mold integral, carries out the position adjustment of mold integral.
