Abstract
The utility model discloses a plaster die for producing quartz crucibles. The plaster die comprises a steel frame disposed at the bottom; a quadrangular plaster bottom die is disposed on the steel frame; four upright dies are disposed on the plaster bottom die; each upright die is corresponding to one side of the plaster bottom die; two opposite vertical faces are large vertical faces; two ends of each of the two large vertical faces are provided with corners; and the other two opposite vertical faces are small vertical faces. Advantages of the plaster die are that: firstly, the plaster die facilitates demoulding and reduces various crack defects caused by demoulding; and, secondly, through the circular arc angle design, the plaster die prevents semifinished products from forming stress concentration herein and thus improves yield of demoulding.
Description
Technical field
The utility model relates to a kind of device that is used to produce quartz crucible, particularly a kind of gypsum mold that is used to produce quartz crucible.
Background technology
Gypsum mold is a power tool important in the quartz crucible production process, directly influences performance of products and qualification rate, and traditional one-sided suction slurry gypsum mold is an integral type; Promptly four facades and base are whole unifications, and its main drawback is-1, and the blank demoulding is difficulty comparatively, and fraction defective higher-2 produces the stress concentration phenomenon in mould corner easily, and crack defect is more; To the shortcoming of traditional moulds, how can effectively overcome its shortcoming becomes technical barrier.
The utility model content
The utility model purpose: the utility model technical problem to be solved is the deficiency to prior art, and a kind of gypsum mold that is used to produce quartz crucible is provided.
In order to solve the problems of the technologies described above; The utility model discloses a kind of gypsum mold that is used to produce quartz crucible, comprise the steelframe that is arranged on the bottom, on steelframe, be provided with a tetragonal gypsum bed die; On the gypsum bed die, be provided with four formwork erections, a limit of the every corresponding gypsum bed die of formwork erection;
Wherein two relative facades are big facade, and its two ends are provided with the turning; Two relative facades are little facade in addition.
In the utility model, be provided with steady brace between adjacent big facade and the little facade.
In the utility model, be provided with steady brace between gypsum bed die and the little facade.
In the utility model, the interior angle at said turning is an arc chord angle.
Beneficial effect: the utility model advantage is following: the first, conveniently stripped, reduce the various crack defects of answering the demoulding to cause; The second, the arc chord angle of mould design can effectively reduce blank and form stress concentration at this, improves the qualification rate of the demoulding.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done specifying further, the above-mentioned and/or otherwise advantage of the utility model will become apparent.
Fig. 1 is the diagrammatic cross-section of the utility model.
Fig. 2 is the vertical view of the utility model.
Embodiment
As depicted in figs. 1 and 2,1,2,3,4 represent the dismountable facade of gypsum mold, wherein, the 1, the 3rd, little facade, the 2, the 4th, big facade, 5 is the gypsum bed die, 6 for supporting the steelframe of gypsum bed die 5, the 7th, steady brace.Wherein 5 and 6 become one after making.When combination the utility model; Set level steelframe 6 earlier; Combine little facade 1,3 through steady brace 7 and gypsum bed die 5 respectively then; And then make up 2,4 two big facades respectively, mainly also be to rely on big facade 2,4 and little facade 1, the steady brace between 37 to position, combine in this anabolic process.When dismounting, the big facade 2,4 of dismantling earlier, the little facade 1,3 of dismantling again.
Concrete method of use is following:
Each unit construction is good, with 5～6 bandages mould is fixed simultaneously, pour the cast slurry into, after 11～12 hours suction slurry moulding, remove redundant sizing agent in the mould, and cleared up the blank surface with scouring pad.After forming room placed 3 hours naturally, the bundling belt of dismantling removed little facade 1,3 and big facade 2,4, after drying 3 hours naturally, and removable blank.
The utility model provides a kind of thinking and method that is used to produce the gypsum mold of quartz crucible; The method and the approach of concrete this technical scheme of realization are a lot, and the above only is the preferred implementation of the utility model, should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.The all available prior art of each integral part not clear and definite in the present embodiment realizes.
