Abstract
The invention discloses a kind of multiway valve casting molding dies, including sandbox, shell and arbor, the shell is arranged in sandbox, the arbor passes through shell, the sandbox and shell are made of molding sand, and the interior of shell is provided with core bore, and the arbor is arranged in core bore, for the both ends protrusion of the arbor in the side of sandbox, the arbor is ceramic arbor.Advantages of the present invention: due to constituting arbor using aluminium oxide and ceramic material, so that the hardness and fusing point of arbor are higher, arbor is not easy to deform after pouring into molten iron, it reduces and floats, the precision of multi-way valve can be ensured to cast, reduce error, and arbor can be extracted out from core bore after processing, so as to reuse, save the cost.
Description
Technical field
The present invention relates to mold, in particular to a kind of multiway valve casting molding die.
Background technique
Multiple directional control valve is by the combination valve based on two or more reversal valve.Reversal valve be by spool and valve body it
Between relative motion change the valve class of the on-off relationship for being connected to oil duct on valve body.It, can be with according to different job requirements
Group closes the subsidiary valves such as safety overflow valve, check valve and Fill valve.It is compared with other kinds of valve, multiple directional control valve has structure
The compact pressure loss is small, and slide valve moving resistance is little, has multidigit function, service life long, the advantages that being simple to manufacture.It is in the prior art
Multi-way valve uses molding sand molding die, and due to needing to pour into molten iron during molding, molding sand can be because MOLTEN STEEL FLOW be generated
Travelling causes error.The generation of this situation in order to prevent in the prior art, it will usually using addition round steel, the i.e. arbor of steel
Molding sand is fixed, to prevent from floating, reduces error.But since the fusing point of steel is lower, it can soften after pouring into molten iron
Deformation, largely still remains large error, and processing is caused to fail, and defect rate is higher.
Summary of the invention
The multiway valve casting that the technical problem to be solved in the present invention is to provide one kind can prevent deformation, reduces mismachining tolerance
Molding die.
In order to solve the above-mentioned technical problem, the technical solution of the present invention is as follows: a kind of multiway valve casting molding die, including sand
Case, shell and arbor, the shell are arranged in sandbox, and the arbor passes through shell, and the sandbox and shell are made of molding sand,
The interior of shell is provided with core bore, and the arbor is arranged in core bore, and the both ends of the arbor are protruded in the side of sandbox, institute
Arbor is stated as ceramic arbor.
Further, the ceramic arbor is made of aluminium oxide and ceramics.
Further, the ceramic arbor is by the aluminium oxide of 92%-97% components by weight percent and the pottery of 3%-7% components by weight percent
Porcelain composition.
Further, the ceramic arbor is made of the aluminium oxide of 95% components by weight percent and the ceramics of 5% components by weight percent.
Further, the outer diameter of the arbor is 5 ㎜, and the internal diameter of the arbor is 2 ㎜.
By adopting the above technical scheme, due to constituting arbor using aluminium oxide and ceramic material so that the hardness of arbor and
Fusing point is higher, and arbor is not easy to deform after pouring into molten iron, reduces and floats, it can be ensured that casts the precision of multi-way valve, reduces and miss
Difference, and arbor can be extracted out from core bore after processing, so as to reuse, save the cost.
Detailed description of the invention
Fig. 1 is side structure schematic diagram of the invention.
Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing.It should be noted that for
The explanation of these embodiments is used to help understand the present invention, but and does not constitute a limitation of the invention.In addition, disclosed below
The each embodiment of the present invention involved in technical characteristic can be combined with each other as long as they do not conflict with each other.
Referring to Fig. 1, present embodiment discloses a kind of multiway valve casting molding die, including sandbox 1,2 and of shell
Arbor 3, the shell 2 are arranged in sandbox 1, and the arbor 3 passes through shell 2, and the sandbox 1 and shell 2 are made of molding sand, institute
It states shell 2 and is internally provided with core bore 31, the arbor 3 is arranged in core bore 31, and the both ends of the arbor 3 are protruded in sandbox 1
Side, the arbor 3 are ceramic arbor.The hardness and fusing point of arbor, resistance to deformation, energy can be effectively improved using ceramic arbor
The floating in casting process is enough reduced, error is reduced.
Feasible, the arbor is made of aluminium oxide and ceramics.The arbor by 92%-97% components by weight percent aluminium oxide
With the ceramics composition of 3%-7% components by weight percent.Preferably, the arbor by 95% components by weight percent aluminium oxide and 5% weight group
The ceramics composition divided.The outer diameter of the arbor is 5 ㎜, and the internal diameter of the arbor is 2 ㎜.Since aluminium oxide is with higher molten
Point, and hybrid ceramic can preferably be formed and can reuse, and it is also smaller that rear deformation quantity is used for multiple times.In forming process,
Directly molten iron is poured into sandbox 1, after to be formed, arbor can be extracted out Reusability.Wherein, the external molding sand of shell 2
The multichannel valve arrangement that shape produces as needed is configured, and the structure division of multi-way valve is formed in the gap between sandbox 1.
In conjunction with attached drawing, the embodiments of the present invention are described in detail above, but the present invention is not limited to described implementations
Mode.For a person skilled in the art, in the case where not departing from the principle of the invention and spirit, to these embodiments
A variety of change, modification, replacement and modification are carried out, are still fallen in protection scope of the present invention.
