Description
Technical field
The present invention relates to the technical field of sand casting, and in particular to the technique that system is poured in a kind of casting series connection.
Background technology
Sand mold is the important component that casting is produced by the method for sand casting.Daily middle steel, iron and most coloured
Metal alloy castings can use the method for sand casting to obtain.In existing technology, when carrying out the casting of casting by sand mold,
All it is that liquid metal is injected into the die cavity of sand mold, so as to realize the casting to casting.In casting process, some solidifications
Region does not obtain the timely and effective feeding of liquid metal or alloy, can form scattered and tiny shrinkage porosite.Specifically, crystallization is worked as
During wider range, after cast(ing) surface crust, there is the resolidified region that wider liquid, a solid-state coexist inside it.After
During continuous solidification, solid is on the increase, and molten metal is divided into many small closed areas.
Of the prior art, it is directly to be injected into the metal water of liquid in the die cavity of one sand mold to carry out casting, so as to
Realize the casting of casting.But this forging type during casting easily occur stomata, sand holes, shrinkage porosite the problems such as, this
Kind of pouring type cause the air in die cavity, some impurity inside liquid metal be difficult to it is quick, smoothly discharge.In addition molten iron
Utilization rate than relatively low, casting yield can be caused low, casting cost it is high the problem of.
Deficiency in the presence of prior art, how can be saved during sand casting material, how
Liquid metal can be allowed smoothly to be flowed into the die cavity of sand mold the quick yield rate for forming casting, how lifting casting how
It is problem to be solved by this invention to reduce casting cost.
The content of the invention
It is an object of the invention to provide a kind of technique of casting series pouring system, to solve in existing casting process
Waste of material, cast the problem of cost is high, yield rate is low.
To achieve the above object, it is described the technical scheme is that providing a kind of technique of casting series pouring system
Series pouring casting sand mold pouring technology the step of include：Sand mold manufactures；Sand mold is connected；Pouring liquid metal；Casting into
Type.
Step 1：Sand mold manufactures；Sand mold manufacture is to manufacture sand mold according to the shape to be carried out casting.The sand mold meeting of making
A casting die cavity is formed, the die cavity of casting is identical with the shape of casting.
Step 2：Sand mold is connected；Sand mold series connection is that sand mold is linked together with the mode of series connection.The mode of sand mold series connection
The sand mold series system of vertical moulding, the sand mold series system of horizontal moulding, the mode of horizontal moulding combination can be divided into.Series connection
Mode reduce cast number, the quantity that lifting once-cast casting is formed.
In the sand mold series system of the vertical moulding, vertical running channel is located at below casting die cavity and vertical running channel and die cavity
There is a certain distance gap, both are connected by ingate, and die cavity and vertical running channel are perpendicular to horizontal plane.The sand mold string of vertical moulding
Connection mode is that vertical connection forms sand mold module together side by side by multiple sand molds, then longitudinally connects the sand mold module of formation
Connect.Running channel through connection is indulged by twice together, and be both provided with the cavity wall of each sand mold in the sand mold module of series connection
Feeding hole.The number of sand mold block coupled in series can be determined according to the demand of reality.In the sand mold series system of vertical series,
Water riser on most middle sand mold model top carries out pouring liquid metal.An oblique running channel is connected under water riser.Oblique running channel
Bottom be connected with cross gate, and the both ends of cross gate connect two vertical running channels respectively, vertical running channel be double fluid to.Each sand mold
Die cavity is connected with an ingate, and it is connected by being connected sand mold die cavity with vertical running channel with running channel.
In the sand mold series system of described horizontal moulding, the bottom surface of casting die cavity is parallel to horizontal plane.Horizontal moulding
Sand mold series system be by the sand mold horizontal connection of making together.In the sand mold series system of horizontal moulding, utilization is most middle
Sand mold water riser poured into a mould, the sprue under water riser is connected to the bottom of a die cavity, and die cavity sets vertical with cavity bottom
Sand mold is connected with each other, is formed and connected by running channel, vertical running channel, and the vertical running channel between sand mold is by blocking mouth break-make, and upper sand mold is with
Frock is connected up and down for sand mold use；
In described horizontal moulding composite pouring mode, the bottom surface of casting die cavity is parallel to horizontal plane.Sand mold horizontal combination
Mode is by the integral lower sand mold of four direct moulding of casting die cavity, and the bottom on the inside of die cavity connects by ingate and cross gate
Connect.Lower sand mold middle position lower bushing water riser, mend core water riser and include sprue, sprue links together with cross gate.
Step 3：Pouring liquid metal；Pouring liquid metal enters the liquid metal of high temperature melt by running channel at water riser
Row cast, and be flowed into the sand mold die cavity of each series connection.According to the difference of sand mold series system, liquid after pouring liquid metal
The type of flow of state metal is different.
Step 4：Casting exhaust shaping；Casting exhaust shaping is after liquid metal cast, passes through steam vent and sand mold
Gap gas is discharged；And feeding is carried out according to the actual shrinkage porosite situation of casting, form casting.The process of exhaust is golden from liquid
Category is entered in the die cavity of casting and begun to, and is exhausted by the gap of steam vent and sand mold.During exhaust, liquid
State metal gradually condenses, and ultimately forms casting.
The inventive method has the following advantages that：By the way that sand mold is connected, casting is set to be saved during manufacture
Founding materials, the yield rate for reducing casting cost, improving casting.Solve and cast waste of materials, casting in the prior art
The problem of cost is high, yield rate is low.
