Abstract
The present invention relates to a rapid shaping method for ceramic parts. First, three-dimensional shaping software is used for generating a three-dimensional physical model of a ceramic part which needs manufacturing; then, layering software is used for layering the three-dimensional physical model to obtain the shape of each layer; after melted, paraffin is injected into a tank and is pressed into paraffin sheets by a paraffin roller; according to the shape of the three-dimensional physical model in the first layer after the three-dimensional physical model is layered, the paraffin sheets are engraved by a cutting tool; paraffin slurry which contains ceramic powder is poured into the part hollowed out of the paraffin layer; according to the shape of next layer, paraffin sheets are repetitively made on the layer surface of the layer above, the paraffin sheets are engraved, and paraffin slurry which contains ceramic powder is poured into the part hollowed out of the paraffin layer; finally, a needed three-dimensional prototype entity is obtained; the paraffin of the manufactured three-dimensional prototype entity is removed; after the paraffin removal, the three-dimensional prototype entity is sintered to obtain the needed ceramic part. In the present invention, by the advantages that paraffin can be quickly solidified, the stiffness of the paraffin is low, the paraffin is easily processed, etc., after the three-dimensional physical model is rapidly shaped and superposed layer by layer, the paraffin of the three-dimensional prototype entity is removed, and the three-dimensional prototype entity is sintered into the ceramic part, which can greatly reduce production cost and shorten the production cycle.
Description
Technical field
The present invention relates to a kind of quick forming method, particularly a kind of quick forming method of ceramic part.
Background technology
The traditional preparation process method of ceramic part has casting, injection moulding, extrusion molding, hydrostatic pressing etc., ceramic part with these method preparations generally needs to make earlier model, and the simple shape that is shaped, forming speed is slow, can not rapidly prototype be turned materially entity.Utilizing RP technique to prepare ceramic part can significantly reduce the production cycle, improves speed of production, but comparatively ripe at present RP technique also exists some problems.For example laminated entity manufacturing technology is that raw material is produced ceramic member with the ceramic membrane of The tape casting preparation, and the intensity of ceramic member is very low and following process is complicated; Fusion sediment is shaped ceramic powder and organic binder bond is mixed, and squeezes silk then, fires, and the shrinkage factor of the ceramic member of making is than the exclusion process complexity of big and organic binder bond.Other quick forming method such as stereolithography, select that the territory is laser sintered or the like also to exist the production cost height, and the ceramic part composition of making is single and the problems such as requirement that do not reach machinery or physical property.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, proposed the quick forming method of a kind of production cost ceramic part low, with short production cycle.
For achieving the above object, the preparation method that the present invention adopts is: the three-dimensional entity model that at first generates the ceramic part that needs manufacturing with 3D sculpting software, with delamination software three-dimensional entity model is carried out layering then, promptly adopt the cross section layer mode that three-dimensional entity model is divided into a series of thin layers that thickness is 0.1～2.0mm, obtain every layer shape; With injecting the cell body of volume behind the melted paraffin wax, wax is pressed into the wax disk(-sc) that thickness is 0.1～2.0mm with the wax roller greater than the ceramic part of needs manufacturing; According to the shape of the ground floor three-dimensional entity model after the layering, with cutter wax disk(-sc) is carried out through-carved work, the paraffin powder of carving blows away with hair-dryer; The wax slurry of the ceramic powder that contains mass fraction 70～90% of 70～120 ℃ of fusions is poured in the part of wax layer hollow out, again with scraper will be unnecessary wax starch and blow the formation ground floor off; In cell body, re-inject the paraffin after the fusing, wax is pressed into the wax disk(-sc) that thickness is 0.1～2.0mm with the wax roller; According to the shape of the second layer three-dimensional entity model after the layering, with cutter wax disk(-sc) is carried out through-carved work, the paraffin powder of carving blows away with hair-dryer; The wax slurry of the ceramic powder that contains mass fraction 70～90% of 70～120 ℃ of fusions is poured in the part of wax layer hollow out, again with scraper will be unnecessary wax starch and blow the formation second layer off; The shape of one deck repeats to make the wax slurry that wax disk(-sc), through-carved work and perfusion contain ceramic powder on the aspect of last layer under the basis successively, obtains required three-dimensional prototype entity at last; The three-dimensional prototype entity of making is carried out de-waxing under 150-300 ℃, obtain required ceramic part carrying out sintering more than 900 ℃ behind the de-waxing.
The present invention utilizes paraffin to solidify rapidly, hardness is low, be easy to process and low cost and other advantages and be raw material with quite ripe at present injection moulding wax slurry, adopt the principle that is shaped fast, successively after the stack, pass through de-waxing heat treatment again, Low fire ceramic spare can greatly reduce production costs and shortens the production cycle.
