Abstract
The utility model provides a quartz ceramic crucible die, which comprises an outer die (1), an inner die (3) and a demoulding pressure plate (2) arranged between the outer die (1) and the inner die (3). A cavity (7) is provided between the outer die (1) and the inner die (3). The bottom of the inner die (3) is equipped with a grouting hole (5) communicating with the cavity (7). One side of the bottom of the inner die (3) is covered with porous material (6) close to the cavity (7). Since the bottom of the inner die of the quartz ceramic crucible die is covered with porous material, the generation of bubbles at the bottom of a crucible after the moulding process by utilizing conventional dies is avoided. Therefore, the qualified rate of crucibles is increased.
Description
Technical field
The utility model relates to a kind of mould, belongs to the mechanical device field.Be a kind of mould that is used for making quartz ceramic crucible specifically.
Background technology
The fused quartz ceramic crucible is the easily-consumed products in the polycrystalline silicon ingot casting process.Along with the explosive growth in photovoltaic market, the demand of crucible also increases day by day, and the size of crucible is also increasing simultaneously.Traditional slip casting method is the requirement of incompatibility crucible size development more and more, and the emerging notes type that congeals into can overcome the unfavorable factor of slip casting method, thereby has extraordinary development prospect.The mould of annotating the method for coagulating mostly is stainless steel mould, in use has some insoluble problems.Especially slip has been taken out after the vacuum, in the process of cast, see in a small amount of bubble unavoidably, also there is a certain amount of gas to generate simultaneously in the solidify reaction process, and stainless steel mould does not absorb the function of bubble, so be easy to cause have in the bottom of crucible after the moulding bubble of a spot of or minute quantity, thereby the qualification rate of crucible is difficult to guarantee.
The utility model content
The technical problems to be solved in the utility model is: a kind of quartz ceramic crucible mould is provided, and it can reduce the bubble that produces in the bottom of crucible after the common die moulding, thereby improves the qualification rate of crucible.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: 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 cavity in described internal mold bottom, the bottom of described internal mold is coated with porous material near the one side of cavity, as gypsum etc.
According to quartz ceramic crucible mould described in the utility model, be preferably described internal mold top and also be provided with steam vent, described steam vent is connected with described cavity.
According to quartz ceramic crucible mould described in the utility model, be preferably the center that described injected hole is arranged on the internal mold bottom.
According to quartz ceramic crucible mould described in the utility model, be preferably described external mold and form by plural parts.Preferably, described external mold is made up of two side members and a terrestrial components.
According to quartz ceramic crucible mould described in the utility model, being preferably described external mold is a global facility.It is designed to one, wait internal mold to deviate from after, green compact slightly shrink, holding green compact with vacuum cup can the smooth demoulding.
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.
Description of drawings
Fig. 1 is the cutaway view of quartz ceramic crucible mould described in the utility model;
Fig. 2 is the partial enlarged drawing of quartz ceramic crucible mould shown in Figure 1.
The specific embodiment
Below for a more detailed description to the utility model in conjunction with the accompanying drawings with embodiment.Present embodiment only is the description to the utility model preferred forms, scope of the present utility model is not had any restriction.
Embodiment:
As shown in Figure 1, be the cutaway view of quartz ceramic crucible mould described in the utility model.Described quartz ceramic crucible mould comprises external mold 1, internal mold 3 and is in demoulding platen 2 between described external mold 1, the internal mold 3, and between external mold 1 and internal mold 3, there is cavity 7, be provided with the injected hole 5 that is connected with described cavity 7 in internal mold 3 bottoms, be preferably the center that is arranged on internal mold 3 bottoms.One side at the close described cavity 7 in the bottom of internal mold 3 is coated with porous material 6, as materials such as gypsum.
Preferably, can also be provided with steam vent 4 at top, internal mold 3 two ends, this steam vent 4 is communicated with described cavity 7.
And external mold 1 can be made up of plural parts, and as being made up of two side members and a terrestrial components, it also can manufacture a global facility.External mold 1 design is in aggregates, wait internal mold 3 to deviate from after, green compact slightly shrink, holding green compact with vacuum cup can the more smooth demoulding.
In use, who fully soaks with deionization internal mold 3 bottoms earlier, and interior then external mold spraying releasing agent is so that the demoulding is standby after set of molds installs.The vitreous silica sand slip that is mixed with chemical reagent such as monomer, crosslinking agent, initator injected hole 5 slip castings from the internal mold center have been taken out after the vacuum to cavity 7.After slip casting is finished, mould is put into drying room or water bath is cured.Curing is finished post-tensioning and is gone out mould, in the high humidity environment bottom knockout.Slough internal mold 3 earlier, demoulding this moment platen 2 is pushed down green compact, in order to avoid green compact are taken out of with internal mold 3, takes away demoulding platen 2 then, holds and pull out the crucible green compact with vacuum cup, is positioned over dry room and carries out drying.
In above-mentioned solidification process, the bubble that can be mingled with minute quantity in the slip, generate a small amount of bubble in addition during curing reaction, the discharge of directly floating of the bubble of green compact wall part, the bubble floating of bottom is to the mould inner bottom surface, be coated with porous material 6 (as shown in Figure 2) on it, it can absorb above-mentioned bubble, thereby ensures that crucible surface does not have obvious air blister defect.
The smooth zero defect in green compact outside of quartz ceramic crucible mould preparation described in the utility model, inside only bottom surface need polish a little, and other place all need not processing.Its energy one-shot forming, very convenient easy operating, and green compact can not form defective because of there being bubble to generate in the solidify reaction process, the qualification rate of raising crucible.
