The utility model has simple structure, good green compact surface quality of the centrifugation formed gradual-change bore diameter perforated pipe, easy stripping and high success rate, which is conducive to industry bulk production of the gradual-change bore diameter perforated pipe.
Description
Technical field
The utility model relates to the technology of die manufacturing field, especially relates to a kind of mould for preparing the gradual-change bore diameter antipriming pipe.
Background technology
The gradual-change bore diameter porous material of centrifugal deposition method preparation can solve high filtering precision and big this a pair of contradiction of Air permenbility, but such material is not realized industrial mass manufacture at present.Its main cause is, after gradual-change bore diameter antipriming pipe centrifugal deposition was shaped, the operation of the stripping process of gradual-change bore diameter antipriming pipe required than higher, demoulding difficulty, misoperation gradual-change bore diameter antipriming pipe will be scrapped because of cracking, and this has limited applying of gradual-change bore diameter antipriming pipe greatly.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned deficiency of the prior art, a kind of mould for preparing the gradual-change bore diameter antipriming pipe is provided, it is simple in structure, the gradual-change bore diameter antipriming pipe green compact surface quality of centrifugal formation is good, the demoulding is easy and success rate is high, helps the industrial mass manufacture of gradual-change bore diameter antipriming pipe.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of mould for preparing the gradual-change bore diameter antipriming pipe, comprise the external mold of forming by mould loam cake and mould lower cover, it is characterized in that: be provided with the two halves formula in the described external mold folding rigid pipe mould, described two halves formula is made up of the pipe die one and the pipe die two of symmetrical semicircular ring structure folding rigid pipe mould, and the inner space after pipe die one and pipe die two combinations is a metal dust suspension spatial accommodation.
Two folding ends of described pipe die one and pipe die two are provided with the positioner that cooperatively interacts and use.
Two folding ends of described pipe die one are provided with alignment pin, and two folding ends of described pipe die two are provided with the position-arresting hole that matches with described alignment pin.
Described two halves formula is placed with round table-like suspension briquetting to folding rigid pipe mould inside upper part, and the inwall of described pipe die one and pipe die two is provided with the step that is used to place the suspension briquetting, and described step is consistent with the height of suspension briquetting.
The outside of described pipe die one and pipe die two is provided with external screw thread, and is connected threadably with the mould lower cover with the mould loam cake.
The utility model compared with prior art has the following advantages: 1, simple in structure, easy to use.2, the novel two halves formula that is provided with in external mold of this use is to folding rigid pipe mould, and like this, the gradual-change bore diameter stainless steel antipriming pipe demoulding of centrifugal generation is easy and success rate is high, has improved production efficiency, reduces production costs.3, the two halves formula is provided with positioner to the folding end of folding rigid pipe mould, so the two halves formula is to folding rigid pipe mould good stability in use, and be placed with the suspension briquetting in rigidity pipe die inner and upper, the effect of the also restricted location of suspension briquetting 6 metal dust suspension liquid level, so use the novel gradual-change bore diameter stainless steel antipriming pipe thickness that makes of this use even, good product quality.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

The specific embodiment
As Fig. 1, Fig. 4 and shown in Figure 5, the utility model comprises the external mold of being made up of mould loam cake 7 and mould lower cover 8, be provided with the two halves formula formed by the pipe die 1 and the pipe die 22 of symmetrical semicircular ring structure in the described external mold to folding rigid pipe mould, and the inner space after pipe die 1 and pipe die 22 combinations is a metal dust suspension spatial accommodation.This design has guaranteed that the prepared gradual-change bore diameter antipriming pipe green compact demoulding is easy and success rate is high.
In conjunction with Fig. 2, two folding ends of pipe die 1 and pipe die 22 are provided with the positioner that is used.In the present embodiment, two folding ends of described pipe die 1 are provided with alignment pin 4, two folding ends of described pipe die 22 are provided with the position-arresting hole 5 that matches with described alignment pin 4, the cooperation of alignment pin 4 and position-arresting hole 5 makes the relative position of pipe die 1 and pipe die 22 stable, and the situation of waste product can not take place to cause because of the position skew in casting flospinning process.
As shown in Figures 2 and 3, described two halves formula is placed with round table-like suspension briquetting 6 to folding rigid pipe mould inside upper part, the inwall of described pipe die 1 and pipe die 22 is provided with the step 3 that is used to place suspension briquetting 6, and described step 3 is consistent with the height of suspension briquetting 6.Suspension briquetting 6 plays the effect of location to metal dust suspension liquid level in the flospinning process of metal dust suspension, and the gradual-change bore diameter antipriming pipe thickness that it is obtained after shaping is even, the demoulding easily.
The outer setting of pipe die 1 and pipe die 22 has external screw thread, and mould loam cake 7 and mould lower cover 8 inside are provided with internal thread, and is connected threadably with mould lower cover 8 with mould loam cake 7.
The course of work of the present utility model is: with two folding ends of pipe die 1 and pipe die 22 to good, and be screwed on the mould lower cover 8 by threaded engagement, powder of stainless steel suspension, titanium alloy powder suspension, alumina powder suspension or other metal dust suspension for preparing is poured in pipe die 1 and the pipe die 22 inboard die cavitys, metal dust suspension liquid level with pipe die 1 and pipe die 22 in step 3 concordant being as the criterion; Then suspension briquetting 6 is put on the step 3; At last mould loam cake 7 is screwed on pipe die 1 and the pipe die 22, at this moment, mould loam cake 7 and mould lower cover 8 are installed in the outside of pipe die 1 and pipe die 22 as external mold; External mold is put on the centrifuge, utilizes centrifugal action that metal dust suspension is adjacent on the inwall of pipe die 1 and pipe die 22, and natural deposition formation; The centrifugal formation gradual-change bore diameter of metal dust suspension antipriming pipe green compact, respectively mold removal loam cake 7 and mould lower cover 8 take off suspension briquetting 6 again, pipe die 1 and pipe die 22 are put in the baking oven together with gradual-change bore diameter antipriming pipe green compact dry; After the oven dry, separately pipe die 1 and pipe die 22 just obtain gradual-change bore diameter stainless steel antipriming pipe.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of technical solutions of the utility model.
