Description
Technical field
The invention belongs to technical field of mold, more specifically to a kind of white template construct method of reducing pipe.
Background technology
Lost foam process produces tapered pipe fitting, and since specification is too many, mold does not have versatility, needs mold developing too many, takes
With surprising, factory can use foam wooden handcart system substantially, and the tube surface finish produced is bad, a dozen qualification rates are low
(20%-30%), and since wall thickness is difficult to accurately control, the universal overweight 10-20% of pipe fitting, and normal mold developing production
Pipe fitting, negative common difference is in 10-15%.Use the reducing pipe production cost of evaporative pattern production high in the prior art, qualification rate is low, needs
It is further improved.
Invention content
Present invention aim to address problems of the existing technology, provide a kind of make simply, for producing reducing pipe
Cost can be reduced, the white template construct method of reducing pipe of reducing pipe qualification rate is improved.
To achieve the goals above, the technical solution that the present invention takes is：The white template construct of this reducing pipe provided
Method, which is characterized in that include the following steps：1) mould is made；2) straight panel is spliced；3) spliced straight panel is wrapped in mould
On outer surface；4) straight panel is cut into half stencil body；5) two symmetrical half stencil bodies are spliced into white stencil body；6)
It is vertically connected with flange in white stencil body, forms white template.
To keep above-mentioned technical proposal more detailed and specific, the present invention also provides optimization technique sides further below
Case, to obtain satisfied practical function：
Mould outer diameter described in step 1) is identical as reducing pipe internal diameter size to be produced.
The thickness of the straight panel is identical as tapered tube thickness.
Half of outer surface of straight panel winding covering mould after the splicing.
Half stencil body is formed to cut in face of straight panel cut with mould upper and lower end face and middle axial plane in step 4).
Compared with prior art, the present invention haing the following advantages：The white template construct method of reducing pipe of the present invention makes simple
Efficiently, the white template of making is adopted this method for producing reducing pipe, and the reducing pipe surface smoothness of production greatly improves, and closes
Lattice rate greatly improves, and reduces production cost, has preferable application prospect.

Specific implementation mode
Below against attached drawing, by the description of the embodiment, making to the specific implementation mode of the present invention further details of
Explanation.
This white template construct method of reducing pipe of the present invention, includes the following steps：1) mould 1 is made；2) straight panel is spliced；3)
Spliced straight panel is wrapped on 1 outer surface of mould；4) straight panel is cut into half template 41；5) by two symmetrical half templates
41 are spliced into white stencil body；6) it is vertically connected with flange in white stencil body, forms white template 4.
The white template construct method of reducing pipe of the present invention, 1 outer diameter of mould and tapered bore to be produced in step 1)
Size is identical.Type is made by using foam fire truck in mould 1, vehicle at reducing pipe mould 1 identical with internal diameter size above and below reducing pipe,
By splicing existing straight panel, as shown in Figure 1, splicing on demand, spliced straight panel can wind covering half of appearance of mould 1
Face is used in combination band 3 that straight panel is fixed on mould 1 as shown in Figure 2, is cut convenient for follow-up.
It is cut in face of straight panel with mould upper and lower end face and middle axial plane to cut in step 4), forms half template, such as Fig. 3
It is shown.For ease of cut, can be used marking pen along the upper and lower end face boundary line of mould 1 marking on straight panel corresponding position,
Along the upper following of label line clipping straight panel；Axial plane is marked in straight panel both sides and is crossed along mould 1, and straight panel is cut along mark line
Both sides.Straight panel 2 after cropped forms half template as shown in Figure 4, is repeating step 2) to 4) on the other half mould surface
Symmetrical another half of half module plate 41 is formed, then two symmetrical half template, 41 sides are spliced to form to the white template of reducing pipe
Ontology, by being separately connected upper corresponding upper flange 42 in the upper and lower side of white stencil body and lower flange 43 constitutes time reducing pipe
White template, for casting reducing pipe.
In the present invention, thickness straight panel identical with tapered tube thickness is selected, the size and weight accuracy of reducing pipe can be improved.
The white template construct method of reducing pipe of the present invention uses straight panel using the mould 1 of macrofoam plank one reducing pipe of vehicle system
It is wrapped in 1 surface of mould, the straight-through white stencil body of reducing pipe being extended into is formed after cutting, through being spliced to form the white mould of reducing pipe
Plate.In the present invention, each specification mould can be used continuously, and for producing the white template of reducing pipe, adopt this method the white of making
For producing reducing pipe, the reducing pipe surface smoothness of production greatly improves template, a dozen qualification rates reach 95%-98% it
Between, no longer overweight, production efficiency doubles, and saves cost, saves 2066 yuan through measuring and calculating is per ton, year creates about 200,000 yuan of effect.
The white template construct method of reducing pipe of the present invention, making are simple and efficient, and the white template for adopting this method making is used for
Reducing pipe is produced, the reducing pipe surface smoothness of production greatly improves, and qualification rate greatly improves, and reduces production cost, tool
There is preferable application prospect.
The present invention is exemplarily described above in conjunction with attached drawing, but the present invention is not limited to aforesaid way, only
It wants the improvement of the various unsubstantialities of methodology and technical solution progress using the present invention or directly applies to other occasions
, it all falls in protection scope of the present invention.
