Abstract
The improving technique of guide rail cast casting, it belongs to guide rail casting field.In modeling process, one end, guide rail sand mold chamber of guide rail foundry goods near sprue gate, other end remote pouring mouth, one end of remote pouring mouth connects earthenware; One end of earthenware is inserted in guide rail sand mold chamber, and the other end inserts in the sand mold chamber of foundry goods base, and earthenware is communicated with the sand mold chamber of guide rail sand mold chamber and foundry goods base; During cast, molten steel enters guide rail sand mold chamber by the one end near sprue gate, is full of guide rail sand mold chamber gradually, continues by earthenware the sand mold chamber entering foundry goods base.For easily causing impurity, pore or dirty position in foundry goods, adopting earthenware to be communicated to if foundry goods base etc. is to the undemanding position of internal request, making above-mentioned defect can not occur in foundry goods key position, reach casting design requirement.
Description
Technical field
The present invention relates to the improving technique of guide rail cast casting, it belongs to guide rail casting field.
Background technology
Guide rail foundry goods often uses in modern mechanical is produced, especially heavy-duty machinery.Technical requirement and the quality requirement of guide rail foundry goods are higher, and many positions of foundry goods all require to carry out defect detecting test, can not have any casting flaw, guide rail planing surface, journal stirrup, and the interior tissue at the positions such as two ends requires fine and close.In the casting process of casting, most cast by guide rail one end of guide rail foundry goods, molten steel flow to the guide rail other end gradually, then flow to the elsewhere of guide rail foundry goods.In this process, the guide rail other end is blind end, and the thing that drops in the impurity in molten steel and molding sand is assembled at the other end of guide rail foundry goods gradually.Cause the impurity of the other end of guide rail, pore or dirty more after solidifying, affect the quality of guide rail foundry goods.
Summary of the invention
In view of the defect that prior art exists, the invention provides the improving technique of guide rail casting, adopt the mode of water conservancy diversion, the guide rail other end is become open end, the thing that drops in impurity in molten steel and molding sand cannot be assembled at the other end of guide rail foundry goods, improve the quality of guide rail foundry goods.
For achieving the above object, the technical solution adopted in the present invention is: the improving technique of guide rail cast casting, and casting technique comprises moulding, mould assembly, cast, knockout, cleaning, and ball blast is antirust.In modeling process, one end, guide rail sand mold chamber of guide rail foundry goods near sprue gate, other end remote pouring mouth, one end of remote pouring mouth connects earthenware; One end of earthenware is inserted in guide rail sand mold chamber, and the other end inserts in the sand mold chamber of foundry goods base, and earthenware is communicated with the sand mold chamber of guide rail sand mold chamber and foundry goods base; During cast, molten steel enters guide rail sand mold chamber by the one end near sprue gate, is full of guide rail sand mold chamber gradually, continues by earthenware the sand mold chamber entering foundry goods base.
After adopting such scheme, compared with prior art there is following beneficial effect: for easily causing impurity, pore or dirty position in foundry goods, earthenware is adopted to be communicated to if foundry goods base etc. is to the undemanding position of internal request, make above-mentioned defect can not occur in foundry goods key position, reach casting design requirement.

Fig. 2 is the schematic side view of guide rail foundry goods formative technology.
In figure: 1, guide rail sand mold chamber, 2, foundry goods base, 3, earthenware, 4, sprue gate.
Detailed description of the invention
For understanding the improving technique of guide rail cast casting in depth, composition graphs 1 and Fig. 2 are described as follows:
The improving technique of guide rail cast casting, casting technique comprises moulding, mould assembly, cast, knockout, cleaning, ball blast, antirust, in modeling process, one end, guide rail sand mold chamber 1 of guide rail foundry goods near sprue gate 4, other end remote pouring mouth 4, one end of remote pouring mouth 4 connects earthenware 3; One end of earthenware 3 is inserted in guide rail sand mold chamber 1, and the other end inserts in the sand mold chamber of foundry goods base 2, and earthenware 3 is communicated with the sand mold chamber of guide rail sand mold chamber 1 and foundry goods base 2; During cast, molten steel enters guide rail sand mold chamber 1 by the one end near sprue gate 4, is full of guide rail sand mold chamber 1 gradually, continues by earthenware 3 the sand mold chamber entering foundry goods base 2.
According to rail length and the position of guide rail foundry goods, select suitable earthenware, conventional guide rail foundry goods selects the diameter of earthenware to be 40mm, and earthenware is arc hollow pipe.During moulding, in advance earthenware is put into sandbox, connection guide rail one end and foundry goods base fixed position.Sand mold chamber is the cavity of the shape-designing according to guide rail foundry goods, fills molten steel during for pouring into a mould in cavity, is the moulding of guide rail foundry goods after cooling and shaping.
For easily causing impurity, pore or dirty position in foundry goods, such scheme can be adopted, this position is communicated to if foundry goods base etc. is to the undemanding position of internal request by earthenware, makes above-mentioned defect can not occur in foundry goods key position, reach casting design requirement.
