Abstract
It the utility model is related to a kind of bent axle sand layer being applied in Iron Mould Coated Sand, the bent axle sand layer is the profile according to die crank in swage and is set along its contour edge to bent axle internal stretch, include die crank at least more than two in the swage, include at least two connecting rod arc sections in each die crank, the bent axle sand layer of 2-3mm is provided with the inside of each connecting rod arc section, the bent axle sand layer of 6-7mm is provided with the outside of connecting rod arc section.The utility model is changed temperature field during casting solidification, so as to change the solidification sequence of casting, ensure that the quality of casting, solve the defects of cast-internal shrinkage porosite, shrinkage cavity by the design to sand layer different-thickness.
Description
Technical field
It the utility model is related to Sand-Faced Metal Mould Casting bent axle field, and in particular to a kind of bent axle being applied in Iron Mould Coated Sand
Sand layer.
Background technology
At present, in the technique of Sand-Faced Metal Mould Casting bent axle, usually precoated sand is ejected into swage using injection equipment
The edge of die crank forms sand layer, due to the consistency of thickness of existing sand layer, causes the bent axle produced, through examining
Afterwards, find usually occur the defects of shrinkage cavity and porosity at crankshaft-link rod position, segregation phenomena occurs for cast(ing) surface material, causes hard
Angle value uniformity is very poor.
The content of the invention
In consideration of it, the purpose of this utility model is that, there is provided one kind can be to avoid generation shrinkage cavity, contracting at crankshaft-link rod position
The bent axle sand layer being applied in Iron Mould Coated Sand of loose defect.
In order to reach above-mentioned purpose of utility model, and then the technical solution taken is as follows：
A kind of bent axle sand layer being applied in Iron Mould Coated Sand, the bent axle sand layer is according to die crank in swage
Profile is simultaneously set along its contour edge to bent axle internal stretch, includes die crank at least more than two in the swage,
Include at least two connecting rod arc sections in each die crank, the bent axle of 2-3mm is provided with the inside of each connecting rod arc section
Sand layer, the bent axle sand layer of 6-7mm is provided with the outside of connecting rod arc section.
The beneficial effects of the utility model：
The utility model changes temperature field during casting solidification, so as to change by the design to sand layer different-thickness
Become the solidification sequence of casting, ensure that the quality of casting, solve the defects of cast-internal shrinkage porosite, shrinkage cavity.
Brief description of the drawings
The attached drawing for forming the part of the application is used to provide a further understanding of the present invention, the utility model
Schematic description and description is used to explain the utility model, does not form the improper restriction to the utility model.In attached drawing

Member's all other embodiments obtained without making creative work, should all belong to the model of the application protection
Enclose.
As shown in Figure 1, a kind of bent axle sand layer being applied in Iron Mould Coated Sand, the bent axle sand layer is according to swage 1
The profile of middle die crank 2 is simultaneously set along its contour edge to bent axle internal stretch, include in the swage 1 at least two groups with
On die crank 2, in this example, the number of die crank 2 is 4 groups, and at least two connecting rods circle is included in each die crank 2
Segmental arc 3, has 4 in this example, the inner side 4 of each connecting rod arc section 3 is provided with the bent axle sand layer of 2-3mm, connecting rod arc section 3
Outside 5 be provided with the bent axle sand layer of 6-7mm.
The utility model changes temperature field during casting solidification, so as to change by the design to sand layer different-thickness
Become the solidification sequence of casting, ensure that the quality of casting, solve the defects of cast-internal shrinkage porosite, shrinkage cavity.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the present invention, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on, should be included within the scope of protection of this utility model.
