Iron Castings.
Description
Technical field
The utility model belongs to Foundry Production technical field, is easily cut more particularly to a kind of iron casting with ultra-thin riser
Piece.
Background technique
Currently, in the Foundry Production of G. Iron Castings, the defects of generating shrinkage cavity and porosity in order to avoid casting, generally all in ball
Ironware heat knot or thick big position are provided with riser, separate in order to facilitate the riser of G. Iron Castings with casting ontology, and do not damage magnesium iron
Generally riser pad is arranged in riser lower end in casting ontology.
Existing riser pad is mostly the universal architecture in Foundry Production, and the thickness of cameron core is thicker, is unfavorable for structure
Complicated iron casting uses, and separating difficulty is big, and existing riser pad production inconvenience and high production cost, while its
Heat preservation, heating effect are poor.
Utility model content
The utility model in order to solve the problems in the prior art, proposes a kind of ultra-thin riser pad of iron casting.
To achieve the above object, the utility model uses following technical scheme: a kind of iron casting is easily cut with ultra-thin riser
Piece, it includes cameron core ontology, the first liquid-passing hole and the second liquid-passing hole, and the cameron core ontology is truncated cone-shaped, the cameron core
Ontology is made using precoated sand, and with a thickness of 4mm~7mm, first liquid-passing hole is located at cameron core ontology truncated cone-shaped center,
First liquid-passing hole is up big and down small truncated cone-shaped hole, and second liquid-passing hole is cylindrical cavity, the second logical liquid
Hole cylinder diameter is identical as the first liquid-passing hole truncated cone-shaped osculum end diameter to be connected to one, and first liquid-passing hole and second are led to
The height of fluid apertures is identical.
Further, the cameron core ontology truncated cone-shaped gradient is 1/6.
Further, the first liquid-passing hole truncated cone-shaped gradient is 1/3.
Further, the cameron core body thickness is 6mm.
Further, the first liquid-passing hole height is 3mm.
Further, the second liquid-passing hole height is 3mm.
Compared with prior art, the utility model has the beneficial effects that the utility model riser pad thickness is thin, very
It is suitble to complicated iron casting to use, knocks out and remain after riser less on casting, be convenient to clean, lower the work of cleaning polishing
Make intensity, improves production efficiency.Riser pad is made using precoated sand, can produce intensity height, thickness is thin to be emitted
Mouth cameron core, need to only make easy tooling in Foundry Production Worksite can produce, and can accomplish first to do first to use, avoid transport
And loss, moisture absorption during storage etc., reduce production cost.Precoated sand has good insulation effect at high temperature, mentions
The high feeding efficiency of riser, is conducive to the feeding of iron casting riser.
Detailed description of the invention

Fig. 2 is a kind of ultra-thin riser pad overlooking structure diagram of iron casting described in the utility model
1- cameron core ontology, the first liquid-passing hole of 2-, the second liquid-passing hole of 3-, A- cameron core ontology truncated cone-shaped gradient, B- first
Liquid-passing hole truncated cone-shaped gradient
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely illustrate.
Illustrate present embodiment referring to Fig. 1-2, a kind of ultra-thin riser pad of iron casting, it includes cameron core ontology
1, the first liquid-passing hole 2 and the second liquid-passing hole 3, the cameron core ontology 1 are truncated cone-shaped, and the cameron core ontology 1 uses precoated sand
It is made, with a thickness of 4mm~7mm, first liquid-passing hole 2 is located at 1 truncated cone-shaped center of cameron core ontology, the first logical liquid
Hole 2 is up big and down small truncated cone-shaped hole, and second liquid-passing hole 3 is cylindrical cavity, 3 cylindrical straight of the second liquid-passing hole
Diameter is identical as 2 truncated cone-shaped osculum end diameter of the first liquid-passing hole to be connected to one, first liquid-passing hole 2 and the second liquid-passing hole 3
It is highly identical.
1 truncated cone-shaped gradient of cameron core ontology described in the utility model is 1/6, and the 2 truncated cone-shaped gradient of the first liquid-passing hole is
1/3.The preferred thickness of cameron core ontology 1 is 6mm in the present embodiment；The preferred height of first liquid-passing hole 2 is 3mm；Second logical liquid
The preferred height in hole 3 is 3mm.
The cameron core ontology 1 is made of precoated sand, is used cooperatively with heat preservation riser buss, is passed through the utility model
With the collective effect of heat preservation riser buss, riser supplement shrink efficiency is improved, reduces molten iron dosage.In the present embodiment, cameron core is thick
Degree is 6mm, and maximum outside diameter 120mm, the diameter of liquid-passing hole 3 is 30mm, and matched exothermic riser sleeve outer diameter is 120mm,
The opening of the small disc of the rotary table of cameron core ontology 1 and exothermic riser sleeve is bonded together when use.This preferred implementation
Riser volume is about 906.5cm in column3, it is 7.07kg full of weight of molten iron, by Experimental Comparison, does not use the utility model solidifying
Gu weight average is 6.3kg, for riser solidification weight average for 5.7kg, each riser can more feeding after using the utility model
0.6kg molten iron；Simultaneously using after the utility model, riser ontology is connect by the cylinder of original diameter 120mm with iron casting
Become riser ontology and iron casting connection diameter as the cylinder of 30mm, sectional area is by 11304mm2Become 706.5mm2, using people
Work percussion can strike down riser, not injure casting ontology, and without cutting, riser remnants are less on casting, easy cleaning.This
