Description
Technical field
The invention belongs to casting field, and in particular to a kind of casting technique positioned using peripheral core positioning datum piece.
Background technology
Casting is more complicated, during the casting of very irregular, can face and larger cavity is produced with model, afterwards close to cavity wall
It is put into the fuse made（Peripheral core）, the scheme of final die cavity is formed afterwards.And peripheral fuse lower end easily positions,
And fuse particular location can not determine, and all it is the face of strike-ofing on the outside of peripheral fuse, size is forbidden, and processing is with digital control processing now
Based on, profile takes three direction black skins as machining benchmark, often due to peripheral group core is forbidden to cause machining benchmark to offset, from
And influence Mechanical processing of casting size offset.
The content of the invention
In view of the defects of above-mentioned prior art, the concrete scheme that the present invention uses is a kind of using peripheral core positioning datum
The casting technique of piece positioning, including molding, moulding, core, mould assembly, cast, knockout, cleaning, ball blast and antirust are made, its patternmaking process
In, model is connected with bottom plate, the marginal position of model and contacts baseplate sets some peripheral core positioning datum pieces.
The model with some peripheral core positioning datum pieces is extracted during the moulding, is put into peripheral core afterwards, according to
The groove that some peripheral core positioning datum pieces leave on molding sand in patternmaking process, stretched with cotton rope and examine peripheral core position
Whether size is accurate, if peripheral core will definitely not be adjusted by line, then peripheral core back side back-up sand is fixed.
It is preferred that peripheral core positioning datum piece is set perpendicular to bottom plate, and perpendicular to the side of model.
The position that peripheral core positioning datum piece is set determines according to the size of the peripheral core to be produced.
The casting technique model positioned using peripheral core positioning datum piece, its model are connected with bottom plate, model and bottom
The marginal position of plate contact sets some peripheral core positioning datum pieces.It is preferred that the position root of the peripheral core positioning datum piece
Determined according to the size of the peripheral core to be produced.
It is preferred that peripheral core positioning datum piece is vertical with the side of model, at the same it is vertical with the bottom plate.
Beneficial effects of the present invention：The present invention is to be used for casting mold surrounding by the molecular casting technique of core, wherein casting mold four
The fuse in week is referred to as peripheral core, and the method ensure that the positional accuracy of peripheral core, so as to ensure that machining accuracy.

Embodiment
The present invention is to be referred to as peripheral sand by the molecular casting technique of core, the fuse of wherein casting mold surrounding for casting mold surrounding
Core, this casting as shown in Figure 6 is more complicated, during the casting of very irregular, larger cavity is typically first produced with model, afterwards
The fuse made is put into close to cavity wall（Peripheral core）, final die cavity is formed afterwards.
The casting technique positioned using peripheral core positioning datum piece, including molding, moulding, make core, mould assembly, pour into a mould, falling
Sand, cleaning, ball blast and antirust, in its patternmaking process, model 5 is connected with bottom plate 4, the marginal position that model 5 contacts with bottom plate 4
Insert some peripheral core positioning datum pieces 6.
The model 5 with some peripheral core positioning datum pieces 6 is extracted during the moulding, is put into peripheral core 1, root afterwards
According to the groove that some peripheral core positioning datum pieces 6 leave on molding sand in patternmaking process, stretched with cotton rope and examine peripheral core
Whether position dimension is accurate, if peripheral core will definitely not be adjusted by line, then peripheral core back side back-up sand is fixed.
It is preferred that peripheral core positioning datum piece 6 is inserted perpendicularly into the side of model 4.
The position that peripheral core positioning datum piece 6 is inserted is true according to the size of the peripheral core 1 to be produced
It is fixed.
The casting technique model positioned using peripheral core positioning datum piece, its model 5 is connected with bottom plate 4, model 5 and
The marginal position that bottom plate 4 contacts sets some peripheral core positioning datum pieces 6.It is preferred that the peripheral core positioning datum piece 6
Position determines according to the size of the peripheral core 1 to be produced.
It is preferred that peripheral core positioning datum piece 6 is vertical with the side of model 5, at the same it is vertical with the bottom plate 4.
Feature of the present invention is that the peripheral i.e. peripheral core of top box face outline spacer of core 1 is made on the bottom plate 4 of model 5
Positioning datum piece 6, positioning datum piece 6 is directly extracted during moulding, stretched after lower core with cotton rope and examine the peripheral position dimension of core 1 to be
No accurate, if core will definitely not be adjusted by line, then core back side back-up sand is fixed, and the method ensure that the position of peripheral core is accurate
Property, so as to ensure that machining accuracy.In addition, bottom plate 4 is connected with model 5 so that model is more easy to take out.The present invention can also process such as
The complicated die cavity of moulding shown in Fig. 2 and Fig. 3.
