Abstract
The utility model provides a manufacture mould for quartz ceramic crucible which can make a crucible have a low porosity and guarantee the compactness and antiseepage of the crucible; the stress of seams of a formed crucible is dispersed so as to ensure the normal use of the crucible. The manufacture mould comprises an external mold and an inner mould, characterized in that an opening of the external mold is downward, and the opening side edge of the external mold is inverted over the peripheral edge of the inner mould; a core portion of the inner mould is located in a cavity of the external mould; an upper end sealing surface of the external mould is provided with casting material apertures; the interior surface of the external mould shows an arc surface for transition, and the external surface of the inner mould shows an arc surface for transition.
Description
Technical field
The utility model relates to the technical field of the crucible of making polysilicon, is specially a kind of making mould of quartz ceramic crucible.
Background technology
Existing polysilicon is to adopt multiple material is mixed in the crucible, then the multiple material of crucible and inside thereof is put into burner hearth together and carries out sintering, obtains the polysilicon silicon ingot, and crucible is abandoned.
The mould of existing crucible comprise internal mold 1, external mold 2, its structure is seen Fig. 1, internal mold 1, the seam crossing of external mold 2 is straight transitions, the open side 3 of external mold 2 up, internal mold 1 is loaded in the cavity of external mold 2, uncovered cast slurry makes slurry filled internal mold 1, external mold 2 formed cavitys 4, because its uncovered cast, its porosity height is so make the compactness of crucible, barrier properties is poor, in addition, because internal mold, the seam crossing of outer mill is straight line or right angle transition, and the seam crossing of crucible also is a straight line, causes the stress of crucible seam crossing to be concentrated, it is being made, storage, easily produce breakage in the transportation, influence the normal use of crucible.
The utility model content
At the problems referred to above, the utility model provides a kind of making mould of quartz ceramic crucible, and it makes that the porosity of crucible is low, guarantees compactness, the barrier properties of crucible, and makes the stress of seam crossing of the crucible after the moulding disperse, and guarantees the normal use that exceeds.
A kind of making mould of quartz ceramic crucible, its technical scheme is such: it comprises external mold, internal mold, it is characterized in that: the open side of described external mold down, the open side edge back-off of described external mold is in the edge of described internal mold, the mould heart of described internal mold partly is positioned at the cavity of described external mold, the upper end closed face of described external mold has material hole, and the inner surface of described external mold is the arc surface transition, and the outer surface of described internal mold becomes the arc surface transition.
It is further characterized in that: four angles of the inner surface of described external mold are fillet, and four angles of the outer surface of described internal mold are fillet.
After adopting structure of the present utility model, slurry has reduced the contact of slurry in air by the cavity between material hole filled internal mold, the external mold, can avoid air along with slurry enters cavity together, thereby reduced the porosity of crucible, guaranteed compactness, the barrier properties of crucible; Because the inner surface of external mold is the arc surface transition, and the outer surface of internal mold becomes the arc surface transition, and the seam crossing that produces crucible is the arc surface transition, make the stress of seam crossing disperse in addition, guarantee the normal use that exceeds.
