Abstract
The utility model discloses a casting device for elongated through holes of a metal casting piece, which comprises a casting box and a seamless steel pipe arranged in the casting box, wherein the center position in the seamless steel pipe is transversely penetrated through a metal core pipe, and resin bonded sands are filled between the inner wall of the seamless steel pipe and the outer wall of the metal core pipe; both ends of the seamless steel pipe are provided with opening end plugs capable of supporting the metal core pipe to the center position of the seamless steel pipe, and both ends of the metal core pipe are tightly locked on the casting box by a screw bolt; a lumen section on the metal core pipe, which is positioned in the seamless steel pipe, is provided with an air inlet hole, and an outer side end of the metal core pipe, which is positioned on the opening end plugs, is provided with a pin; an air exhausting hole communicated wit the lumen of the metal core pipe is formed in the screw bolt. The utility model has the advantages of reasonable structure and design, convenient operation and low cost, and not only solves the disadvantage of large investment for devices and cutter tools needed by mechanical processing, but also solves the disadvantages of easy bending, easy deformation, and easy iron-liquid sticking to rejection of a former cast-in seamless steel pipe.
Description
Technical field
The utility model relates to a kind of casting device, particularly relates to a kind of metal casting slightness hole casting device of using for metal casting casting slightness hole.
Background technology
The approach that forms slightness hole on the metal casting has two kinds.A kind of is method by machining, carries out drilling deep hole from two ends and forms slightness hole, so not only needs expensive equipment, be deep hole drilling machine, also need a large amount of frocks and cutter to process so elongated through hole, output investment ratio is bigger, long processing time, the cost height; Another kind of approach is to form elongated through hole by casting method, casting method has multiple, a kind of is to form elongated through hole by the mud core, the mud core that this kind method is made is carefully grown, the distortion of mud core appears under gravity and molten iron buoyancy function easily, rupture and core sintering under the high temperature liquid iron effect, the rough inner surface in hole, problems such as the linearity in hole is poor, though this kind method is through improving, adopt the method for the profound through hole of water-cooled arbor casting steel-casting, during casting-up or cast back is by the logical cooling water of water-cooled arbor, though its advantage has overcome the core sintering, problems such as steel burning into sand reach under the shorter situation of mud core without stud, overcome stud and merged problem, but can't solve the elongated hole rough inner surface, the linearity in hole is poor, if under the long situation of slightness hole without stud, distortion appears in elongated mud core under gravity and molten iron buoyancy function, problems such as fracture, but also will be by the cooling of water-cooled arbor when cast or after the cast, cooling effect is difficult to grasp.Another kind of method in the casting method is to be cast into seamless steel pipe to form elongated through hole, support and fixing seamless steel pipe with the mud stud, and on seamless steel pipe the welding sheet of fluxing, prevent that seamless steel pipe merges bad, crooked, distortion in the casting process, the shortcoming of this kind method is: use stud, make stud and matrix merge the bad seepage that causes easily; The welding sheet of fluxing has changed the tissue and the intensity of seamless steel pipe welding position, causes the seamless steel pipe that is cast into to be easy to burn through under the effect of high temperature liquid iron, can't clear up and scraps.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, a kind of reasonable in design, easy operating is provided and is cast into the metal casting slightness hole casting device that seamless steel pipe is not flexible, be out of shape and do not glue molten iron.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of metal casting slightness hole casting device, it comprises sandbox 2 and the seamless steel pipe 4 that is arranged in the sandbox 2, it is characterized in that: a metal-cored pipe 5 has been crossed in the centre in the described seamless steel pipe 4, be filled with resin sand 8 between seamless steel pipe 4 inwalls and metal-cored pipe 5 outer walls, seamless steel pipe 4 two ends are provided with the opening plug 3 that metal-cored pipe 5 is supported on seamless steel pipe 4 centres, 6, the two ends of metal-cored pipe 5 are locked on the sandbox 2 by bolt 1, be positioned at seamless steel pipe 4 tube chamber sections on the metal-cored pipe 5 and have air admission hole 9, be positioned at opening plug 6 outboard ends on the metal-cored pipe 5 and be provided with pin 7, have the steam vent 12 that communicates with metal-cored pipe 5 tube chambers in the bolt 1.
The utility model compared with prior art has the following advantages: the utility model reasonable in design, easy operating, with low cost, both solved the big shortcoming of machining equipment needed thereby and cutter investment, be cast into before having solved again that seamless steel pipe is flexible, distortion, sticking molten iron and the shortcoming of scrapping.
