Description
Technical field
The invention belongs to casting technology field, the ventilation type sand core system of specifically a kind of wind power casting casting.
Background technique
In the prior art, for the casting of intermediate aperture in casting, aperture segment is mostly by core moulding.Type core is being cast
Preposition intracavitary in type, after molten iron pours into condensation, taking-up/removing when shaking out can form the corresponding cavity of aperture in casting.Iron
Water cooling is affected to the quality etc. of casting.Optimal state is the intracavitary each section molten iron synchronous cooling of type.It is practicing
In, this be it is impossible, usual mode is the cooling effect for optimizing various pieces as much as possible by cavity design.And due to
The volume of the casting of wind power product is larger, and in most cases, type core position is surrounded by molten iron, the cooling velocity of this position
Far below other positions.Especially for casting cavity in irregular shape, cooled down currently without preferable method, in order to
Guarantee casting quality, can only be reached by the high request to casting process, and the difficulty of technique control is larger.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the invention proposes a kind of gas of wind power casting casting
Cold type sand core system.The type core is made of the molding sand package metallic framework for being mixed with moulding sand binder；The metallic framework
Structure are as follows:
Including multiple groups air inlet pipe and an air outlet pipe, in every group of air inlet pipe and an air outlet pipe: air inlet pipe is sleeved in escape pipe, the two
Between gap be outlet passageway, the end of escape pipe is closed；
The head end of each group escape pipe is connected to same closed hollow cylinder；A piece inlet manifold is inserted into hollow circle from top
Cylinder, and connect with the air inlet of the recent pipe of each group；A piece outlet general pipeline is inserted into hollow cylinder, and the air inlet of outlet general pipeline from top
Mouth is at the top of hollow cylinder.
Further, the axis direction on the outer wall of the escape pipe along escape pipe is connected with multiple steel discs in turn.(facilitate
Molding sand adherency)
Gusset is connected between the outer wall and hollow cylinder outer wall of the escape pipe.(gusset has reinforced structure and has
The double action for helping molding sand to adhere to)
Inlet manifold and outlet general pipeline are connected on hollow cylinder vertically, and inlet manifold and outlet general pipeline are wrapped up by molding sand,
The top of the type core of this part has circular platform type boss, and boss facilitates protective conduit, and keeps the temperature to the air in pipeline.
Core pulling pull ring is externally connected in outlet pipe end.
The gas outlet of the air inlet pipe is divided into main gas outlet and multiple separates port；Main gas outlet is located at the end of air inlet pipe
End, multiple ports that separate are opened on the tube wall of air inlet pipe.
The principle and effect of the technical program are to enter the hollow interior of type core by cold air, take away heat, carry out cold
But, it preferably solves the problems, such as the cooling of specific position molten iron, is reduced as far as each section molten iron difference cooling time, optimizes
The matrix of casting avoids since local grain caused by inhomogeneous cooling is coarse, influences overall mechanical properties.
Detailed description of the invention
Fig. 1 is the principle schematic diagram of this type core；
Fig. 2 is the appearance structure schematic diagram of this type core；
Fig. 3 is the schematic diagram using casting made from this type core；
In figure: type core 1, air inlet pipe 2, escape pipe 3, hollow cylinder 4, inlet manifold 5, outlet general pipeline 6, steel disc 7, gusset 8,
Boss 9, core pulling pull ring 10, main gas outlet 11, casting 12.
Specific embodiment
This case is further illustrated with specific embodiment with reference to the accompanying drawing:
Such as Fig. 1~2, a kind of ventilation type sand core system of wind power casting (such as Fig. 3) casting, the type core is by being mixed with type
The molding sand package metallic framework of sandbinder is constituted；The structure of the metallic framework are as follows:
Including multiple groups air inlet pipe and an air outlet pipe, in every group of air inlet pipe and an air outlet pipe: air inlet pipe is sleeved in escape pipe, the two
Between gap be outlet passageway, the end of escape pipe is closed；
The head end of each group escape pipe is connected to same closed hollow cylinder；A piece inlet manifold is inserted into hollow circle from top
Cylinder, and connect with the air inlet of the recent pipe of each group；A piece outlet general pipeline is inserted into hollow cylinder, and the air inlet of outlet general pipeline from top
Mouth is at the top of hollow cylinder.
In this example, the axis direction on the outer wall of the escape pipe along escape pipe is connected with multiple steel discs in turn.It is described go out
Gusset is connected between the outer wall and hollow cylinder outer wall of tracheae.
Inlet manifold and outlet general pipeline are connected on hollow cylinder vertically, and inlet manifold and outlet general pipeline are wrapped up by molding sand,
The top of the type core of this part has circular platform type boss.
Core pulling pull ring is externally connected in outlet pipe end, and under type wick-like state, pull ring is wrapped up by molding sand.Casting is completed to fall
After sand, garland is exposed.
The gas outlet of the air inlet pipe is divided into main gas outlet and multiple separates port；Main gas outlet is located at the end of air inlet pipe
End, multiple ports that separate are opened on the tube wall of air inlet pipe.Due to main gas outlet from end the releasing cool air into escape pipe, through being subcooled
But outlet passageway, during the head end position for reaching escape pipe, temperature is stepped up, and the cooling effect of each section is uneven.It is logical
It crosses design and separates port, can preferably solve this problem.
