Abstract
The utility model provides a porous graphite mould for preparing a quartz crucible. A certain number of small holes are uniformly distributed on the side wall and the bottom of the graphite mould and are filled with porous graphite material. The porous graphite mould for preparing the quartz crucible is reasonable in design, easy for demoulding of the quartz crucible, and convenient and practical in use.
Description
Technical field
The utility model belongs to the crucible die technical field, relates in particular to a kind of preparation quartz crucible with high temperature resistant porous graphite mould.
Background technology
The quartz crucible producing apparatus is a major equipment of producing quartz crucible, and porous graphite mould most important building block during to be quartz crucible found.
Problems such as quartz crucible structure of the prior art makes quartz crucible after preparation is accomplished, be difficult for the demoulding, and the vacuum layer thickness of quartz crucible does not reach requirement or thickness differs, and structure designs such as the heat-insulating property of graphite jig are unreasonable.
Summary of the invention
The utility model problem to be solved provides that a kind of reasonable in design, product is prone to the demoulding, convenient and practical preparation quartz crucible is used the porous graphite mould.
The utility model is drilled with the equally distributed aperture of bleeding in the sidewall and the bottom of graphite jig; The inboard of aperture has different apertures with the outside; Inboard aperture according to the size control of the crucible that will prepare between 4～6mm, aperture, the outside is controlled between 2～3.5mm.The degree of depth of inboard aperture and each ratio of the degree of depth of apertura lateralis are 1:2～2:1, are filled with the porous graphite material in the inboard aperture.
The top of porous mold has outstanding heat insulation step, and this heat insulation step can cover the top of water jacket, reduces the heating degree of water jacket, prolongs its work-ing life.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is that the preparation quartz crucible produced of the utility model is with high temperature resistant porous graphite mould diagrammatic cross-section.
Description of reference numerals: 1 porous graphite die main body; 2 heat insulation steps; 3 inboard aperture; 4 apertura lateralises.
Specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further, but not as the qualification to the utility model.
As shown in Figure 1, a kind of quartz crucible for preparing comprises the aperture of bleeding that heat insulation step and two ends have different diameter with the porous graphite mould, in inboard aperture, is filled with the porous graphite material.Graphite jig is put into water jacket, adopt high-temperature resistant seal ring, graphite jig is fixed on the water jacket on water jacket top and graphite jig contact part.Adopt the substituted traditional asbestos material that causes asbestosis, mesothelioma of pleura easily and contain crystal water of porous graphite material, it has low thermal conductivity, high gas permeability, good characteristic such as high temperature resistant.Adopt the porous graphite material can effectively stop silica sand to be inhaled into vacuum apparatus and stop up the aperture phenomenon with minimizing silica sand.
Above-described embodiment, the utility model embodiment a kind of more preferably just, common variation that those skilled in the art carries out in the utility model technical scheme scope and replacement all should be included in the protection domain of the utility model.
Claims (4)
1. one kind prepares quartz crucible and uses the porous graphite mould, it is characterized in that: at the sidewall of graphite jig and the aperture of bleeding of bottom uniform distribution some amount.
