Simultaneously, injection molding is meant a kind of compression molding method, wherein imports the material of high workability in predetermined mould, obtains the chuck of mold shape.In injection molding, processing mixes and casting in a vacuum as the pottery of jacket material and about 50% binding agent.Then, thus make the mould degreasing from mould, remove binding agent by the thermal treatment under about 500～700 ℃.With the mould sintering of binder free, and alongst, inside and outside processing.At last, at the mould upper cut, therefore finish the preparation of chuck.
Yet above-mentioned extrusion molding and injection molding have following point: (1) since thermal treatment removing the binding agent that in the processed clip cover material, is added, so the preparation method is complicated and loaded down with trivial details; (2), thereby cause the equipment that chuck prepares and the raising of production cost in order to carry out the pottery and the kneading of binding agent, molded and remove binding agent and need kneader, injector or forcing machine and debinding furnace respectively; (3) for the fluidisation ceramic particle, the additional materials processing step for example adding and the vacuum mixing of binding agent is necessary; (4) expensive mould be should prepare in order to pour into a mould chuck, thereby production cost and the competitiveness that is reduced in this field improved.
In order to overcome the problems referred to above, the purpose of this invention is to provide a kind of preparation method of optics chuck, it can reduce the chuck preparation section significantly by making the plaster bandage mold.
Another object of the present invention provides a kind of optics chuck preparation method, and the capillary pressure that facilitates the use gypsum prepares a kind of sleeve.
Another purpose of the present invention provides a kind of preparation method of optics chuck, and it can reduce the cost of chuck significantly.
A kind of preparation method of optics chuck is provided to achieve these goals, here.In the method, make a kind of gypsum slurry, in this gypsum slurry, make the mould of chuck shape, the suspension that will comprise pottery is poured in the mould, stick to by ceramic particle to form one on the surface of mould and adhere to the mould layer, at the fixed time after, from mould, pour out suspension and make the drying die layer, dry this calcium plaster, the drying die layer that forms in mould by dry and sintering is processed this sintered compact and is made chuck to make a kind of sintered compact.
By describing the preferred embodiments of the invention in more detail with reference to appended accompanying drawing, it is clearer that above-mentioned purpose of the present invention and advantage will become, in the accompanying drawings:
Accompanying drawing 1 schematically shows the gypsum mold of embodiment of the present invention, and wherein suspension is cast in this mould with the preparation chuck; With

With reference to appended accompanying drawing the preferred embodiments of the invention will be described in more detail.Should be noted that identical in the accompanying drawings mark is represented same parts, if think that detailed description known function of the present invention and structure can cause indigestion theme of the present invention, should avoid this detailed description so.
Accompanying drawing 1 schematically shows the gypsum mold of the preferred embodiment of the invention, and wherein suspension is cast in this mould to prepare chuck of the present invention.Accompanying drawing 2A-2D schematically shows the preparation process according to embodiment of the present invention chuck.
As shown in Figure 1 the same at first made a column by polyvinyl chloride (PVC), and its diameter is 0.5 millimeter and greater than the outer warp of the chuck 26 shown in the accompanying drawing 2D.Then, thus by the PVC column is put into cementitious gypsum slurry gypsum slurry 10 intaglios carve out mould 12.Then, making a kind of average particle size particle size in 2～4 hours by stirring pottery 18, organic dispersing agent 30, spherical medium 28 and water in one jar 14 is about 0.5 micron suspension 16.Here, pottery 18 is to be made by zirconium white, aluminum oxide or their mixture, and organic dispersing agent 30 has the pH value of acidity or alkalescence to prevent the attraction between the ceramic particle, that is to say the gathering of ceramic particle.In addition, the pH value of organic dispersing agent 30 is not in 7～8 scope, and organic dispersing agent 30 has minimum ζDian Shi.In jar 14, mix with the water of about 40～60 weight % (with total restatement of suspension material) ceramic 18, in jar 14, add the spherical medium 28 that accounts for this jar 14 volumes about 30～50%.
Then, suspension 16 is poured in the gypsum mold 12, and deposited about 5～20 minutes.By the capillary pressure that has only gypsum just to have ceramic particle 18 is sticked on the surface of mould 12, therefore form one and adhere to mould layer 20.During the adhesion that capillary pressure causes, the moisture that is comprised in the suspension reduces.For fear of this situation, a feed-tank can be installed automatically in mould 12, to add suspension 16.
When the internal diameter that adheres to mould layer 20 after at the fixed time reaches the value (for example about 2.5 millimeters) of defined, from mould 12, remove remaining suspension, and reversing ground dried gypsum slurry 10 about 5 minutes or still less.Then, become evenly, so gypsum slurry is turned if adhere to the internal diameter of mould layer 20 in the mould 12.Therefore, adhere to mould layer 20 and become the drying die layer 22 that separates by predetermined slit 28 and mould layer 12.Then, drying die layer 22 and the sintering in the drying die 12 under preset time.Therefore, obtain a kind of sintered compact 24 as shown in the accompanying drawing 2C.Cut away the jut 22a and the 22b that protrude in the both sides of sintered compact 24, process sintered compact 24 then along its length.The otch of processing sintered compact 24, thus finish as the chuck shown in the accompanying drawing 2D.
