The composite mould is simple in structure and easy in manufacture, the inner mould is easily placed in and taken out of the outer mould, and the composite mould is simple in manufacture, easy in casting demoulding and fine in circular degree of castings when in centrifugal casting of the annular castings with circumferential grooves on the outer circumferences.

Description

Centrifugal casting float grease seal ring composite die
Technical field
The utility model relates to a kind of centrifugal casting annular foundry goods and uses mould, and particularly a kind of centrifugal casting excircle has along the annular foundry goods of the circumferential groove compound patrix with mould.
Background technology
Centrifugal casting is that liquid metal is poured in the casting mold mould of rotation, and liquid metal fills type and is frozen into the casting method of annular cast at the casting mold mould under centrifugal action.Centrifugal casting is mainly used in produces hollow rotary body, and centrifugal casting gained THE STRUCTURE OF CASTINGS is fine and close, few, the good mechanical property of non-metallic inclusion; Do not need dead head during centrifugal casting, using rate of metal can improve greatly, to making the foundry goods of some given shape, as: make float grease seal ring, centrifugal casting is a kind of saving material, save energy consumption, casting technique efficiently.Float grease seal belongs to a kind of mechanical seal, and float grease seal has annular float grease seal seat, in the annular float grease seal seat annular float grease seal ring is arranged, and O shape rubber seal ring is arranged between float grease seal seat and the float grease seal ring.
The excircle of float grease seal floating ring has the annular groove along circumference, and groove is used to hold O shape rubber seal ring.The centrifugal casting excircle has behind the float grease seal floating ring of peripheral annular groove; Mould has interference to the demoulding of foundry goods; Have along the annulus of the annular groove of circumference so can not cast out excircle with the method for centrifugal casting, when centrifugal casting float grease seal floating ring, can only cast out excircle is the face of cylinder or the round table surface that does not have groove; After centrifugal casting goes out the float grease seal floating ring foundry goods that excircle is the face of cylinder or round table surface; Method with cut cuts the groove along circumference again, and the float grease seal floating ring of making in this way is waste material both, also expends man-hour.For ability centrifugal casting goes out excircle the float grease seal floating ring along circumferential groove is arranged; In the prior art, Chinese patent 200920187520.2 discloses a kind of centrifugal casting float grease seal ring mould, and this mould has compound patrix of the annular of the company of offseting and circular plate type counterdie; It is L shaped annular external mold that compound patrix has the cross section; External mold is embedded with the float grease seal profile mould of back-off, and the interior circular hole of annular external mold is the sprue gate, and the external mold of this mould, internal mold and counterdie all are metal patterns.Because the excircle of float grease seal ring has the groove along circumference, during casting, need to cooperate forced cooling device to use.During use, liquid metal pours in the centrifugal casting float grease seal floating ring blank mould of rotation, and liquid metal cools off foundry goods with forced cooling device after in die cavity, being frozen into foundry goods, lets foundry goods shrink and the demoulding in the condition lower volume of forcing cooling.The compound patrix of this centrifugal casting float grease seal floating ring blank mould all is to process with metal, excircle is arranged taken off from mould along the annular cast of circumferential groove with the method that lets foundry goods cooling shrink to be not easy very much control; In addition, to the even circular degree that also can influence foundry goods of annular foundry goods inhomogeneous cooling; Because above-mentioned mould is to let foundry goods shrink and the demoulding in the condition lower volume of forcing cooling; Deviate from the metal die cavity in order to help foundry goods; Die cavity is the annular die cavity that is surrounded by external mold, internal mold and counterdie; For this reason, the lower end, the outside of internal mold and the interior hand hay cutter lower end of the external mold limited step that will match makes the making trouble of mould.
Summary of the invention
The purpose of the utility model is in order to overcome above-mentioned deficiency, propose a kind of when the centrifugal casting excircle has the annular foundry goods along circumferential groove, make simple, the foundry goods demoulding easily, centrifugal casting float grease seal ring composite die that the foundry goods circular degree is good.
The utility model is realized with following method.
Centrifugal casting float grease seal ring compound die has the compound patrix of annular and the circular plate type counterdie of the company of offseting, and it is L shaped annular external mold that compound patrix has the cross section, and external mold is embedded with the annular internal mold; The annular die cavity is arranged between external mold, internal mold and the counterdie; External mold and counterdie all are metal patterns, and the internal face of external mold side is a round table surface, and the angle of round table surface and external mold upper surface is 95 ~ 97 degree; Internal mold is the resin sand mo(u)ld; Boss along circumference is arranged on the inner peripheral surface of internal mold, and the upper surface of external mold is evenly equipped with installing hole, die shank is arranged below the counterdie.
The boss of the inner peripheral surface upper edge circumference of the utility model internal mold with the excircle that will cast matching along circumferential groove along the annular foundry goods of circumferential groove arranged.
During use; Be installed in the utility model on the centrifugal casting machine, when driving the utility model rotation, pour into molten metal from the interior annular distance of external mold with centrifugal casting machine; Liquid metal fills type and is frozen into annular cast at the casting mold mould under centrifugal action; Taking off to solidify in the external mold then has the resin of foundry goods sand mo(u)ld, disposes the resin sand mo(u)ld of foundry goods excircle, and just can obtain excircle has the annular foundry goods along circumferential groove.
The patrix of the utility model is that the cross section is on L shaped circular ring metal external mold and the inner peripheral surface compound die that is composited along the annular resin sand internal mold of circumference boss to be arranged; The internal face of L shaped circular ring metal external mold side is a round table surface, and the angle of round table surface and external mold upper surface is 95 ~ 97 degree, and is simple in structure; Be easy to make; Internal mold is packed into easily and is taken out, when the centrifugal casting excircle has the annular foundry goods along circumferential groove, make simple, the foundry goods demoulding easily, the foundry goods circular degree is good.
Below in conjunction with accompanying drawing, the utility model is done explanation further.
