Abstract
The utility model relates to a mould, in particular to a forming mould using fused quartz ceramic slurry as raw materials to manufacture a fused quartz ceramic crucible. The forming mould comprises an inner mould, an outer mould, a pressing disk between the inner mould and the outer mould and a bottom plate, wherein the inner mould, the outer mould, the pressing disk and the bottom plate are in sealing match to jointly enclose a cavity. The forming mould is characterized in that the inner mould comprises an air outlet formed in the center of the bottom of the inner mould, an air hole plug matched with the air outlet, a fixing rod fixedly connected with the air hole plug, a fixing ring for connecting the fixing rod with the inner mould, a slurry injecting port arranged at the top of the inner mould, a slurry discharging port arranged at the top of the inner mould and a notch where a fixing bolt is installed. Openings with the same shape and the same size are formed in the outer mould, the pressing disk and the bottom plate at the positions corresponding to the notch of the inner mould, and through holes with the same shape and the same inner diameter are formed in the pressing disk at the positions corresponding to the slurry injecting port of the inner mould and the slurry discharging port of the inner mould. Compared with the prior art, the forming mould is simple in structure, small in deformation, capable of achieving net-size forming of the crucible and capable of guaranteeing size uniformity of the crucible.
Description
Technical field
The utility model relates to a kind of a kind of mould that relates to, and particularly relating to a kind of is the mould that raw material is made quartz ceramic crucible with the fused quartz ceramic slurry.
Background technology
The fused quartz ceramic crucible is the container that loads polycrystalline silicon raw material in the polycrystalline silicon used for solar battery ingot casting process, and service condition is extremely harsh, is the expendable consumed product in the polycrystalline silicon ingot casting process.Usually adopt the fused quartz ceramic crucible of injection forming owing to phenomenons such as distortion appear in restriction easily that be subjected to mould, and size is inhomogeneous, had a strong impact on crucible performance in use.In order to address this problem, publication number is that the Chinese utility model patent of CN 201998306 U discloses a kind of quartz ceramic crucible mould, comprise external mold, internal mold and be in demoulding platen between described external mold, the internal mold, there is cavity between described external mold and the internal mold, be provided with the injected hole that is connected with described cavity in described internal mold bottom, the bottom of described internal mold is coated with porous material near the one side of described cavity.Quartz ceramic crucible mould described in the utility model covers porous material by the bottom at internal mold, can reduce the bubble that produces in the bottom of crucible after the common die moulding, thereby improves the qualification rate of crucible.Yet because injected hole is arranged on the middle part of internal mold, the top that steam vent is arranged on internal mold, be unfavorable for that the bottom of crucible produces the smooth eliminating of bubble, therefore cover porous material with absorption portion bubble gas in the bottom of internal mold, but porous material has a negative impact to the uniformity of the appearance planarization of the crucible finished product behind the injection forming, fineness, size again.
Summary of the invention
The purpose of this utility model solves the foregoing problems that existing fused quartz ceramic crucible exists just, a kind of mould of new structure is provided, for achieving the above object, the technical solution of the utility model is: the mould of this fused quartz ceramic crucible, comprise platen 3 and base plate 9 between internal mold 1, external mold 2, internal mold 1 and the external mold 2, the cavity 13 that internal mold 1, external mold 2, platen 3 and base plate 9 are sealed and matched and go along with sb. to guard him formation jointly; It is characterized in that described internal mold 1 comprises that its bottom centre arranges a venthole 6, the air plug 6-1 that matches with venthole 6, with the fixed fixed bar 4 of air plug 6-1, be connected and fixed the retainer ring 5 of bar 4 and internal mold 1, be arranged on grouting port 10, the grout outlet 11 at internal mold 1 top and be used for installing and fixing the breach 12 of bolt; On described external mold 2, platen 3 and base plate 9 and internal mold 1 breach 12 relevant positions, all be provided with shape, measure-alike opening; Be provided with shape, through hole that internal diameter is identical in described platen 3 and internal mold 1 grouting port 10, grout outlet 11 relevant positions.
Further, at the top of internal mold 1 internal mold suspension ring 7 are set also, comprise at the outer wall of external mold 2 external mold suspension ring 8 are set.
Further, the top of air plug 6-1 is concave surface.
The utility model compared with prior art, and is simple in structure, and morphotropism is little, realized the dead size moulding of crucible, guaranteed the uniformity of crucible size.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Air plug 6-1, fixed bar 4,5 three parts of retainer ring, also not shown bolt have wherein been omitted among Fig. 2.
The specific embodiment
The utility model is described in further detail with reference to accompanying drawing.
Make square peviform internal mold 1 with thick 16mm stainless-steel sheet, external mold 2, platen 3 and base plate 9, internal mold 1 bottom centre arranges a venthole 6, the air plug 6-1 that matches with venthole 6, with the fixed fixed bar 4 of air plug 6-1, be connected and fixed the retainer ring 5 of bar 4 and internal mold 1, be arranged on grouting port 10, the grout outlet 11 at internal mold 1 top and be used for installing and fixing the breach 12 of bolt; On described external mold 2, platen 3 and base plate 9 and internal mold 1 breach 12 relevant positions, all be provided with shape, measure-alike opening; Be provided with shape, through hole that internal diameter is identical in described platen 3 and internal mold 1 grouting port 10, grout outlet 11 relevant positions.Top at internal mold 1 also arranges internal mold suspension ring 7, comprises at the outer wall of external mold 2 external mold suspension ring 8 are set, and the top of air plug 6-1 is concave surface.
After the various piece of mould finished with the fixing assembling of screw, the dies cavity that ceramic size is injected by grouting port, grout outlet had slurry and flows out when mould was filled with by the time, finished cast.Be cured at a certain temperature.At first sloughing base plate sloughs internal mold then and sloughs the fused quartz ceramic crucible green compact that external mold obtains the certain size specification at last.
Above content be in conjunction with concrete preferred embodiment to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the those of ordinary skill under the utility model, under the prerequisite that does not break away from this utility model thinking, can also make simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
