Description
Technical field
The utility model relates to the riser fields in foundry engieering, more particularly, to a kind of for reducing Mechanical processing of casting amount
Abnormal shape fever subsidy.
Background technique
Casting field is the feeding requirement for meeting casting heat energy-saving position, can generally be placed in heat energy-saving positions such as turning, boss
Feeding head.Conventional riser place when be placed in casting type top of chamber, using riser high mode itself, setting time is long the features such as,
The casting that first solidifies intracavitary to type carries out feeding under the effect of gravity.
For the feeding requirement for solving casting, generally feeding head can be placed in the heat energy-saving position of casting.Conventional riser is placed
When be placed in casting type top of chamber, using riser high mode itself, setting time is long the features such as, it is intracavitary to type under the effect of gravity
The casting first solidified carries out feeding.
The quality requirement of cast member is concentrated mainly on three broad aspects, i.e. form factor, internal soundness, ingredient material at present
Deng.It for the form factor and internal soundness for ensuring casting, needs to take a variety of different process means, as exothermic riser is mainly used
In the feeding for solving the problems, such as casting heat energy-saving position.
Exothermic riser is generally located on the thermal center of casting, the i.e. final solidified position of molten metal, to guarantee the gold of riser buss
Belonging to liquid can supplement and gives casting thermal center, avoid at thermal center because shrinkage cavity caused by solidification shrinkage or it is loose the defects of.For certain
The thermal center of special structural casting, such as " the load carrier rear axle shell casting " of certain factories is in the central part of casting, and riser can not
It is rest directly upon thermal center top.
It has also been found that, the Feeding channel between existing riser buss and casting heat energy-saving position is excessively narrow in the long-term practice of inventor
It is narrow, cause Feeding channel to solidify earlier than casting hot spot, the molten metal in riser buss is caused to be unable to complete to casting thermal center
Feeding.
Utility model content
The purpose of the utility model is to overcome it is above-mentioned there are deficiency, a kind of " heat retaining and exothermal is subsidized with type " is provided, is made
Must subsidize can guarantee the molten metal in the channel using the heat retaining and exothermal characteristic subsidized with type against feeding a casting access sites
It is in liquid for a long time, it is ensured that Feeding channel is unimpeded during entire feeding.
To achieve the goals above, technical solution used by the utility model is as follows:
The utility model provides a kind of special-shaped fever subsidy for reducing Mechanical processing of casting amount comprising fever subsidy ontology,
It is provided with feeding through-hole on fever subsidy ontology, and the ontology is at least constituted by inside and outside two layers, wherein outer layer is thermal insulation layer, interior
Layer is mixed layer, which is arranged alternately by heating layer and insulating layer from top to bottom, and mixed layer and casting contact jaw
For heating layer.
According to a kind of special-shaped fever subsidy of this practical new reduction Mechanical processing of casting amount, further technical solution
Be: the mixed layer with a thickness of ontology one third to half.
According to a kind of special-shaped fever subsidy of this practical new reduction Mechanical processing of casting amount, further technical solution
Be: the mixed layer is topmost insulating layer, and bottom and casting contact jaw are heating layer.
According to a kind of special-shaped fever subsidy of this practical new reduction Mechanical processing of casting amount, further technical solution
Be: the fever subsidy ontology is hollow cylindrical, and mixed layer is at least divided into two layers in vertical direction, and mixed layer is in level side
To being at least divided into two symmetrical regions.
According to a kind of special-shaped fever subsidy of this practical new reduction Mechanical processing of casting amount, further technical solution
Be: in mixed layer two regions in the horizontal direction, the opposite insulating layer of vertical direction and heating layer are staggered.
The utility model has the advantage that compared with prior art
1, the heat retaining and exothermal subsidy of the utility model is made, is had to adjacent molten metal using " heat preservation, fever " material
The effect of heating, heat preservation can effectively ensure that thin-walled, the metal at narrow passage casting position is in liquid for a long time, it is ensured that riser
Feeding channel it is unimpeded.
2, this is subsidized using heat retaining and exothermal, can replace " technique subsidy " traditionally, it can is avoided to guarantee feeding
Channel is unimpeded and specially amplifies the way of certain casting positions sectional area.The subsequent cutting problem in these positions is avoided, also greatly
Width improves the dimensional accuracy of casting.
3, the structure of heat retaining and exothermal subsidy is simple, easy to use, only needs to subsidize heat retaining and exothermal in actual use and place
Normal molding operation is then carried out on the periphery of Feeding channel.
4, the utility model can arrange in pairs or groups according to practical situation and use as an individual accessory, to save
Production cost improves efficiency.
5, its inside is set mixed material layer by the utility model, replaces staggered arrangement, is guaranteeing heating guarantor in this way
While temp effect, reduce the dosage of heating material, to reduce the cost of manufacture of product.
