Description
Technical field
Casting mould is the utility model is related to, more particularly to a kind of cylinder head mould.
Background technology
Permanent mold casting is also known as diecasting, and it is that liquid metals is poured into metal mold, is cast with obtaining a kind of of casting
Make method.Casting mold is made of metal, can be reused several times, and in order to obtain the planform of part, uses metal material in advance
Material makes the mould being adapted to part outer surface, is then put into core in a mold, is then formed between mould and core
One cavity as design of part size, then the metal liquid of mobility is poured into a mould in the cavity, liquid cooling solidification
Required casting can be just formed afterwards.
Fig. 1 is participated in, exactly a kind of casting being molded by metal-mold low-pressure casting, includes cylinder head 1 and sets
Fin 11 on cylinder head 1.Because the arrangement of fin is close, therefore this mould inside was for being molded the groove of fin 11 both
Small and close, during pouring metal melt, the exhaust in groove is not smooth, and gas is easily compatible with molten metal, causes shaping gradual
Easily there is stomata in surface, influences the quality of casting.
Utility model content
The purpose of this utility model is to provide a kind of cylinder head mould, improves the exhaust effect inside die cavity, Jin Erti
The high quality of product.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of cylinder head mould, including cope plate, die shoe and sliding be connected between cope plate and die shoe two
Cavity plate, core is provided between two cavity plates, is enclosed between the cope plate, die shoe, cavity plate and core formed with supply
The die cavity of cylinder head shaping, the cavity plate include some matrix bands to overlap each other, and the end face of the matrix band towards die cavity is opened
The depressed part of fin shaping provided with supply cylinder head, offers the steam vent connected with depressed part on the matrix band.
By using above-mentioned technical proposal, cavity plate is partitioned into some matrix bands, compared to integrally formed cavity plate, led to
The design of overmolding piece, the fin of cylinder head are molded in the groove of matrix band, when cavity plate is spliced by some matrix bands
Afterwards, the hole between matrix band can be used in being vented and radiate, and then the molten metal for enabling to enter in depressed part is complete
Full of depressed part, the gas in depressed part can be excluded directly by steam vent, and the air inside die cavity is without from recessed
The portion of falling into excludes toward the junction motion between two cavity plates and from junction, reduces the stream of the medium-sized chamber internal gas of exhaust process
It is dynamic, and then make the process of exhaust more smooth, reduce the time of contact of die cavity internal gas and molten metal, reduction and molten metal
Compatible gas flow, fin moulding section is reduced because surface caused by air is uneven, makes the surface smooth even of fin, carries
The high forming quality and structural strength of cylinder head fin.
Preferably, being provided with the wedge-shaped slot of insertion matrix band on the cavity plate, it is equipped with and is constrained in the wedge-shaped slot
The wedge of Relative sliding occurs between matrix.
By using above-mentioned technical proposal, can be used in the matching design of wedge-shaped slot of wedge is connected adjacent shaping
Piece, make to keep geo-stationary between adjacent matrix band, so as to limit occur between matrix band it is relative slide, by wedge with
Wedge-shaped slot clamping, during demoulding, without repeatedly extracting matrix band out, disposably all matrix bands can be extracted out, improved
Demoulding efficiency.

First turning part and the second turning part are towards conversely.
By using above-mentioned technical proposal, the first turning part and the second turning part be designed to avoid steam vent directly with
External environment condition connects, and passes through the first turning part and the second turning part, it is possible to increase gas is from die cavity external environment discharge process
Needed for the path passed through, avoid gas from quickly discharging and cause gas to occur chilling phenomenon in the end of steam vent, to shaping
Protecting effect is played in the outer face of piece, while can reduce the entrance of external dust, and the first turning part and the second turning part is anti-
To design, the heat that can be balanced between adjacent matrix band scatters and disappears, and the heat sinking pathway difference between adjacent matrix band can
Avoid local temperature occur between matrix band too high.
Preferably, the wedge-shaped slot is connected with die cavity by steam vent, the wedge is connected to the opening of steam vent
Position.
By using above-mentioned technical proposal, wedge is connected to the aperture position of steam vent and is designed to further to extend
The exhaust pathway of steam vent, after the gas inside die cavity is disposed to steam vent, by between matrix band and wedge
Space is discharged, and because wedge props up the opening of exhaust outlet, be further avoid external dust and is entered inside steam vent.
Preferably, being connected between the matrix band by coupling bar, the end set of the coupling bar has and matrix band
The slipping block of abutting, the slippage slot for slipping block connection is offered on the die shoe.
By using above-mentioned technical proposal, being designed to of slipping block and slippage slot provides guiding in cavity plate extraction
Positioning.
Preferably, offering locating slot on the cope plate, guide pad is provided between the cope plate and matrix band,
The coupling bar is located on guide pad and the sliding of the bolt cap of coupling bar is connected in locating slot.
By using above-mentioned technical proposal, guide pad is designed to, for the clamping between cope plate and matrix band, make
Cavity plate plays the locating effect between cope plate and cavity plate in slipping, and opening up for locating slot can be such that bolt cap uses
In positioning sliding.
Preferably, the guide pad is in triangular prism shaped, it is provided with the cope plate and is embedded leading for sliding for guide pad
To groove.
By using above-mentioned technical proposal, being designed to make to guide pad of triangular prism is played certain in slipping
Guide effect, convenient positioning, while the end of guide groove can be made to be in tip state, two cavity plates is passed through during slipping into
The tip positioning of guide groove, can be maintained at center, and avoiding the occurrence of two cavity plates has the inaccurate feelings of the positioning between cope plate
Condition.
Preferably, the junction of adjacent two cavity plate offers the clamping chamber connected with die cavity, the clamping intracavitary is worn
There is pore-forming post, the pore-forming post is provided with the curved portions being connected on core towards the end face of core.
By using above-mentioned technical proposal, the hole position being designed on forming cylinder head of pore-forming post, pass through clamping
The two-point locating of chamber and curved portions, realize the installation of pore-forming post.
In summary, the utility model has the advantages that：
1st, the cylinder head mould is overlapping and open up on matrix band the design of steam vent by matrix band, can make casting
In forming process, the exhaust of mould is more smooth, reduces the gas flow compatible with molten metal, reduces surface after casting shaping
