The invention discloses a kind of cooling-part structure for casting guide rod hole forming, including hanging the axostylus axostyle of chill and being fixedly mounted on two blocks of symmetrical chills of axostylus axostyle both sides, two chills are shaped as by small half of nearly half of cylinder, the cylindrical cambered surface for the indent that the setting of its middle shaft part is engaged with axostylus axostyle cambered surface under vertical cutting；Two chills embrace axostylus axostyle by the cylindrical cambered surface of indent from both sides, and it is fixedly connected by the threaded connector of radial direction with axostylus axostyle, certain interval be present in the centre of two chills, resin sand is filled with gap, resin sand and the chill of both sides collectively form cylinder, in the cylindrical coating layer of outer wrapping one.The chill structure operation is convenient, good cooling results, can reduce casting flaw, improves the metallographic structure of guide rod wall surface of the hole, improves Oxygen potential, increases the quantity of graphite nodule in tissue.
Description
Technical field
The present invention relates to Foundry Production field, more particularly to a kind of cooling-part structure for casting guide rod hole forming.
Background technology
Injection head plate is the important component of injection mechanism for injection moulding machine, is typically made by casting technique,
Its casting quality directly affects the injection quality and service life of injection machine.Therefore, for injection head plate casting, it is desirable to which it does not have
There is any casting flaw, such as shrinkage porosite, shrinkage cavity, slag inclusion, burning into sand and metallographic structure are abnormal, and contain in its microstructure
The number of graphite is more, and distribution is more uniform, and its quality is better；And its guide rod hole is needed by honing to certain precision, ability
Reach service precision, so also very high to the shape requirement of its guide rod hole.It is preferable in order to reach quality in casting process
Casting, chill is often added in pattern, on the one hand can form the guide rod hole that profile relatively requires, on the other hand may be used
To accelerate cooling velocity to reduce casting flaw, existing technique be typically all used in guide rod hole every sand cooling iron or fritter with
Shape chill, but these technological operations are very inconvenient, and also the cooling effect of chill is very poor, and easily there are various defects in casting,
Such as shrinkage porosite, the content of graphite nodule is very low in the casting of formation, skewness, and the total quality of casting is poor, it is difficult to reaches
The requirement of injection machine.
The content of the invention
The present invention is intended to provide a kind of easy to operate, good cooling results, can reduce casting flaw be used for casting guide rod hole
The cooling-part structure of shaping, gained casting can be made to be well positioned to meet the requirement of injection machine.
A kind of cooling-part structure for casting guide rod hole forming of the present invention, including suspension chill axostylus axostyle and
Two blocks of symmetrical chills of axostylus axostyle both sides are fixedly mounted on, two chills are shaped as by small half of nearly one side of something under vertical cutting
Cylinder, its middle shaft part set the cylindrical cambered surface for the indent being engaged with axostylus axostyle cambered surface；The cylinder that two chills pass through indent
Cambered surface embraces axostylus axostyle from both sides, and is fixedly connected by the threaded connector of radial direction with axostylus axostyle, has one in the centre of two chills
Fixed gap, is filled with resin sand in gap, and the chill of resin sand and both sides collectively forms cylinder, in the cylindrical outer wrapping
One coating layer.
Cooling-part structure of the present invention for casting guide rod hole forming, there is circular arc in casting injection head plate etc.
During the casting of shape guide rod hole, the cylindrical cambered surface match-place of indent in the middle part of two blocks of nearly half of cylindrical chills is claimed to close in axostylus axostyle two
Side, fixed using threaded connectors such as screw or bolts with axostylus axostyle, the potting resin sand between two chills, make cylinder is integrally formed
Profile；Then in its one coating layer of outer coating parcel；The cooling-part is finally put into pouring for casting by axostylus axostyle suspension
Poured into a mould in casting mould with the guide rod hole corresponding position of casting, matched moulds.Due to the presence of the chill structure, in casting cycle, chill energy
Enough preferably to absorb and transmit heat, guide rod wall surface of the hole can be cooled down quickly, so as to improve metallographic at guide rod hole well
Tissue, Oxygen potential is improved, add the quantity of graphite nodule, can also improve the mechanical property of casting guide rod wall surface of the hole.In addition, this hair
The bright described cooling-part structure for casting guide rod hole forming, it is coated with dope layer, can avoid high temperature iron liquid
Chill is directly contacted, destruction and fusion of the high temperature iron liquid to chill is avoided, chill can be protected, chill is made repeatedly
With.Resin sand need to be only knocked open in addition, cooling-part structure is made up of two chills and middle resin sand, during demoulding, unclamp screw thread
Connector, the demoulding is very simply and conveniently.

Embodiment
Such as Fig. 1-7, a kind of cooling-part structure for casting guide rod hole forming, including the axostylus axostyle 2 of suspension chill and solid
Dingan County is mounted in two blocks of symmetrical chills 1 of axostylus axostyle both sides, and two chills are shaped as by small half of nearly one side of something under vertical cutting
Cylinder, its middle shaft part set the cylindrical cambered surface for the indent being engaged with axostylus axostyle cambered surface；The cylinder that two chills pass through indent
Cambered surface embraces axostylus axostyle from both sides, and is fixedly connected by the threaded connector 3 of radial direction with axostylus axostyle, has one in the centre of two chills
Fixed gap, is filled with resin sand 4 in gap, and the chill of resin sand and both sides collectively forms cylinder, in the cylindrical outsourcing
Wrap up in a coating layer.
In the plane of the chill some circular grooves 5, the groove are provided with along axle portion direction is separated by a distance
When in the gap that resin sand is filled between two chills, resin sand can be also filled into groove, so that more conducively hanging sand.
Thickness and casting guide rod hole between the cylindrical arcwall face of axle portion circular groove wall and chill of the chill
Wall thickness is consistent, and cooldown rate faster, can more improve the metallographic structure of guide rod wall surface of the hole so when casting cooling, and increase is more
Graphite nodule content.
The material of the nearly half of cylindrical chill is to use HT200 of the graphite form as A type flake graphites to be preferred, this kind
Material has preferable heat storage capacity, can reach more preferable cooling effect.
The dope layer is zirconium English dope layer, and its thickness is preferred with 0.5-1.0 millimeters.
