Description

A kind of casting mould clamping apparatus

Technical field

The utility model relates to cast clamp art, especially a kind of casting mould clamping apparatus.

Background technique

Existing vertical centrifugal-casting machine majority be manually or semi-automatic vertical centrifugal casting machine, fixture not sufficiently with set Standby actual needs combines, and the positioning of tradition machinery formula fixture can not be rapidly completed, and it is big that operation difficulty is positioned manually, because being centrifuged For the mold of casting machine operation when normal automatic, surface temperature has 350 degrees Celsius or more, and when manual operation needs with various shields Tool, the flexibility of the operation substantially reduced, and in locking, it can not accurately guarantee the big few of coupling mechanism force, exist in centrifugation Very high risk, and since operating flexibility is poor, so locking needs long time, frequently result in mold cooling, Bu Nengman Sufficient technique requirement, and influence yield rate, whole operation process is more complicated cumbersome, and abnormal rate is high when worker operation, and safety is poor, Keep the efficiency of whole equipment very low, is not able to satisfy existing production capacity requirements, and with the requirement of consumer product and technique It is continuously improved, more needs the raising of production efficiency and quality stability, conventional brace needs, which take a significant amount of time, to be positioned And locking, therefore the fixture design of existing centrifugal casting machine is unable to satisfy the requirement of actual production, limits client's production line The performance of function.

Utility model content

For above situation, for the defect for overcoming the prior art, the utility model provides a kind of casting mould and clamps dress It sets, mold clamps that process is cumbersome, and manual labor amount is big in the existing history centrifugal casting machine of effective solution, inefficiency Problem.

Its technical solution solved is that including the platform on centrifugal casting machine, platform is able to rotate, and platform upper end is fixed with perpendicular Straight the first cylinder, the first cylinder is interior to place mold, and mold lower end outside has annular protrusion, and annular protrusion is placed in the first cylinder Interior, the first cylinder upper end is set with the second cylinder, and the first cylinder, through being threadedly coupled, is fixed with the second cylinder on the inside of the second cylinder Annular slab, through there is multiple vertical mandrils on annular slab, through being threadedly coupled between mandril and annular slab, mandril upper end is placed in ring Above shape plate, there is the multiple and one-to-one voussoir of mandril below annular slab, voussoir upper end there are opening upwards and along the first cylinder The T-slot radially opened up, mandril lower end are placed in T-slot, and mandril is not separated with T-slot；The first cylinder upper end medial surface is cone Shape face, voussoir are bevel structure close to the end face of the first cylinder, and when mandril pulls down voussoir, multiple voussoirs are in tapered surface Simultaneously clamping mold is drawn close to the center of the first cylinder under effect.

The fast positioning clamping of mold may be implemented in the utility model clever structure, and quickly fixed and guarantee is to the heart, safety Reliably, it can adapt to high speed centrifugation and cast this severe production environment.

Detailed description of the invention

Fig. 3 is the structure chart of the platform and the first cylinder, hemispherical projections thereon in the utility model.

Specific embodiment

Further description is made to specific embodiment of the present utility model below in conjunction with attached drawing.

It is provided by Fig. 1 to Fig. 3, the utility model includes the platform 1 on centrifugal casting machine, and platform 1 is able to rotate, on platform 1 End is fixed with vertical the first cylinder 2, places mold 3 in the first cylinder 2,3 lower end outside of mold has annular protrusion, annular protrusion Be placed in the first cylinder 2,2 upper end of the first cylinder is set with the second cylinder 4, the first cylinder 2 with the second cylinder 4 through being threadedly coupled, Annular slab 5 is fixed on the inside of the second cylinder 4, running through on annular slab 5 there are multiple vertical mandrils 6, between mandril 6 and annular slab 5 Through being threadedly coupled, 6 upper end of mandril is placed in 5 top of annular slab, has the multiple and one-to-one voussoir 7 of mandril 6 below annular slab 5, The T-slot that there are opening upwards in 7 upper end of voussoir and radially open up along the first cylinder 2,6 lower end of mandril are placed in T-slot, mandril 6 and T Type groove does not separate；2 upper end medial surface of the first cylinder is tapered surface, and voussoir 7 is bevel structure close to the end face of the first cylinder 2, when When mandril 6 pulls down voussoir 7, multiple voussoirs 7 are drawn close under the action of tapered surface to the center of the first cylinder 2 and clamping mold 3。

It is coaxial in order to facilitate mold 3 and the first cylinder 2, there is the cone that Open Side Down on the center of 3 lower end surface of mold There are hemispherical projections in shape pit, 1 upper end of platform, and hemispherical projections are located at the center of the first cylinder 2 and cooperate with pit.

When needing fixing mould 3, the first cylinder 2 is first screwed and disassembled, mold 3 is placed in the first cylinder 2 at this time It is interior, and hemispherical projections and bellmouth cooperate so that mold 3 is placed in 2 center of the first cylinder, then the second cylinder 4 is screwed in the On one cylinder 2, mandril 6 is being screwed at this time, mandril 6 moves down press voussoir 7, and voussoir 7 leans under the action of the conical surface to mold 3 Hold together, clamps mold 3 under the collective effect of multiple voussoirs 7.

In above process, the distance that each mandril 6 moves down should keep equal.

It is worth noting that, the distance between voussoir 7 and annular slab 5 can also first be adjusted, then again by the second circle Cylinder 4 is screwed in the first cylinder 2, can more easily guarantee that voussoir 7 keeps mold 3 and the first cylinder 2 coaxial in this way.

The fast positioning clamping of mold 3 may be implemented in the utility model clever structure, and quickly fixed and guarantee is to the heart, peace It is complete reliable, it can adapt to high speed centrifugation and cast this severe production environment.
