140mm is high：50mm.
During this utility model is realized, inventor has found that prior art at least has problems with：Copper nut institute
It is aluminium bronze with material, the trade mark：ZCuAl10Fe3, it has good non-oxidizability and good wearability, but uses aluminium bronze
During mo(u)lded piece, the defects such as shrinkage porosite, slag inclusion are easily produced, and chemical property vivaciously can be reacted with water at high temperature due to copper
Gas is generated, pore occurs so as to be easily caused inside copper nut.If producing copper nut using traditional sand casting mode, by
Interior ectocine is easily subject in sand casting, can cause various defects, such as slag inclusion, pore, contracting inside copper nut, easily occur
Hole etc..
Utility model content
Technical problem to be solved in the utility model is to provide a kind of centrifugal casting special-shaped nut, it is to avoid slag inclusion, shrinkage cavity
The centrifugal casting mould of the profile nut of the defects such as shrinkage porosite, pore.
In order to solve above-mentioned technical problem, the technical scheme adopted by this utility model is：A kind of centrifugation of profile nut
Casting mould, has：

Specific embodiment
It is to make the purpose of this utility model, technical scheme and advantage clearer, new to this practicality below in conjunction with accompanying drawing
Type embodiment is described in further detail.
Referring to Fig. 1, a kind of centrifugal casting mould of profile nut, have：
Bed die, bed die are provided with mounting groove；
Lining mould, serves as a contrast mould and is arranged in the mounting groove of bed die, and lining mould is provided with die cavity, and die cavity includes the nut with profile nut
The rectangular cavity being adapted and the circular cavity being adapted with the screw rod of profile nut；
Cover plate, lining mould is enclosed in the mounting groove of bed die；
Pouring basin, stretches in die cavity through cover plate.
Pass through pin connection between bed die and lining mould.
Lining mould periphery is provided with pattern draft.
The workpiece of centrifugal casting be revolving body, but the cylinder on this aluminium bronze nut top be revolving body, bottom it is hollow
Cuboid is non-revolved body, belongs to irregularly-shaped castings.Therefore there is certain difficulty in this nut of centrifugal casting, and the key of the present invention is：If
One bed die of meter and lining mould.Die joint is selected at the maximal projection of foundry goods, from the length and width face diagonal of the hollow cuboid in bottom
Typing, as shown in Fig. 2 lining mould is divided into two Hough faces, such typing can also reduce error when Hough face closes.This
Outward, two alignment pins are set on Hough face, the accuracy of two Hough faces closure can be improved.Leave necessarily in the depanning direction of lining mould
Gradient, be easy to from bed die take out, lining mould can also be protected；According to this aluminium bronze height of nut H=100mm, table look-up and must rise
Mould gradient is 1mm, as shown in Figure 3.
Centrifugal casting：Molten metal is poured in the casting mold of rotation, under the influence of centrifugal force filling cast solidification forming
A kind of casting method.Centrifugal casting must adopt centrifugal casting machine, for providing the condition of rotation；According to casting mold rotation axiss
In the position in space, centrifugal casting is divided into two kinds of vertical centrifugal casting and horizontal type centrifugal-casting.The characteristics of centrifugal casting, molten metal
Filling, molding and solidification under the action of the centrifugal force, metal feeding effect are good, and cast structure is fine and close, and the defect such as pore, slag inclusion is few,
Therefore its mechanical property is higher；Casting hollow foundry goods does not need the metal consumption of running gate system and runner system, and rate of metal can
Greatly improve.But, alloying component can not be dissolved each other or when the density of early solidification precipitate differs larger with molten metal matrix,
Centrifugal casting easily forms gravity segregation；Foundry goods bore area is rougher, poly- to have slag, and its size is difficult correct control.In a word, it is right
For the foundry goods of some given shapes, centrifugal casting is a kind of material-saving, saves energy consumption, the technique of high benefit, but must be especially
Note taking effective safety measure.
Using horizontal type centrifugal-casting.Before casting, Hough face is first closed, then lining mould is put in bed die, cover cover plate；So
After start casting machine, rotating speed is 1440r/min；Coat, prevent metal heat-conducting too fast, while also plaing a part of to protect casting mold；
Mobile casting trolley, its pouring basin is put in the die cavity of rotation；Using quantitative pouring；Discharge water cooling, accelerates rate of cooling, outward
Surface can obtain the tissue of densification；After foundry goods cooling, shut down；Lining mould is taken out from bed die, Hough face is opened and is taken out copper nut
Foundry goods.
After above-mentioned structure, simple structure is easy to operate, lining mould is put in bed die when casting every time, and startup is poured
Note machine can be produced.Production efficiency is high, and finishing operations are few, saves labour force.The dense structure of foundry goods, quality are high, performance
On can meet use requirement.
This utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that this utility model is implemented not to be received
The restriction of aforesaid way, as long as employing changing for the various unsubstantialities that method design of the present utility model and technical scheme are carried out
Enter, or it is not improved by it is of the present utility model design and technical scheme directly apply to other occasions, in this utility model
Protection domain within.
