Abstract
The utility model provides an immersion ladle casting mould, includes, mold core base, and mold core post, the mold core post is established on the mold core base, in this technical scheme, the mold core post including be located in the middle of the inner core and with the inseparable a plurality of outer core of laminating in inner core side, the side surface that outer core deviates from the inner core is equipped with the burr that gathers at even or officious announcement interval. The ladle nozzle and the densely covered burr of the bit map of slag line portion face of this mould preparation, the pouring in -process has increased the contact surface with the molten steel, divides the heat dissipation capacity, avoids the mouth of a river and slag line position the fracture to appear owing to the rapid liter of temperature, and the ladle structural stability who is prepared by this mould is good, longe -lived, mold core post subassembly is few, simple structure, and in the use, dimensional stability is high, and the installation is fixed convenient to the drawing of patterns is convenient, does not harm rough casting.
Description
Technical field
This utility model belongs to mould applications, is specifically related to a kind of immersion ladle casting mould.
Background technology
Immersion ladle casting mould generally comprises core rod, the fixing seat of fixing core rod, with the gum cover that core rod and fixing seat form closed housing.Traditional slab its core surface of submersed nozzle mould is flat face, its mouth of a river of immersion ladle using this die casting is flat face with slag lining, during pour steel, heat undue concentration when molten steel is in contact with it, can not get sharing, cause the mouth of a river to be ftractureed with slag line binding site temperature shock；Although taking the mode trap heat at the mouth of a river Yu slag line surface-coated insulating inner lining at present, but the mouth of a river and slag lining remain as flat face, and molten steel lacks drag, big to flat face insulating inner lining impulsive force, and high temperature is peeled off serious, and follow-up heat-blocking action is poor.Traditional steel ladle pouring mould core mainly has monolithic devices and combination die core pattern, and its shape of monolithic devices core rod is tight with the laminating of spray inner chamber, and spray is easily caused damage by demoulding difficulty；Combination mold core is typically to be designed to cast shape privileged sites by core rod decomposable some core assemblies, its structure is complicated, core assembly part dimension is less, after long-term production, casting mould can deform, cause product blank dimension to change, not only bring and do not take off mould, and easily cause blank base substrate to damage, qualification rate production efficiency is the lowest, thus adds and manufacture cost.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of immersion ladle casting mould.
For solving the problems referred to above, the technical scheme that this utility model provides is: a kind of immersion ladle casting mould, including, core base, and core rod post, described core rod post is located on described core base, in the technical program, inner core that described core rod post includes being positioned at centre and the some outer core fitted tightly with inner core side, outer core deviates from a side surface of inner core and is provided with and is evenly or unevenly spaced densely covered burr.Gather burr for ladle nozzle prepared by this mould and slag lining surface, casting process increases the contact surface with molten steel, dispersion heat avoids the mouth of a river and slag lining fracture occur owing to temperature rises sharply, this mould the ladle structural stability prepared is good, and the life-span is long.
Further, described core rod post includes four outer cores, and described inner core is cuboid, and outer core is fitted tightly on four sides of described inner core respectively.The inner core of core rod post and outer cored structure are simple, and the reliability combined closely is high, first take out cuboid inner core, thus have sufficient space to deviate from outer core, be convenient in demoulding, do not damage ladle blank during the demoulding.
Further, the outer wicking surface of described core rod post is provided with uniformly and continuous print ripple.The ripple of outer wicking surface comprises concave convex texture, and ladle nozzle and the slag lining of corresponding preparation form concave convex texture, are conducive to increasing further pour steel contact area, improve ladle structural stability and service life.
Further, the ratio of the pitch of waves λ and wave amplitude h of described ripple is 1/3～40, experiment proves that, above-mentioned parameter the asperities surface that its mouth of a river of ladle of the ripple casting limited and slag lining are formed can reach optimal thermal resistance usefulness and buffering usefulness.
Further, described core base is provided with fixing groove, is provided with pin block in described fixing groove, is provided with matched groove bottom described inner core, described inner core is set on pin block fixing by groove, and the fixing groove of outer core insertion is vacated position and is fixed on core base.Core rod column assembly is few, simple in construction, and during use, dimensional stability is high, is arranged and fixed conveniently.
Further, also include core rod Jiao Gai, described core rod Jiao Gai and outer core are provided with supporting latch and pin-and-hole, and described core rod Jiao Gai and inner core are provided with supporting installing hole and screw, and inner core and outer core top are fixed on integrally by described core rod Jiao Gai by latch and screw.
The utility model has the advantages that:
1. gather burr for the ladle nozzle that prepared by this mould and slag lining surface, the contact surface with molten steel is increased during steel ladle pouring, dispersion heat avoids the mouth of a river and slag lining fracture occur owing to temperature rises sharply, and ladle structural stability prepared by this mould is good, and the life-span is long.
2. inner core and the outer cored structure of core rod post are simple, and the reliability combined closely is high, first take out cuboid inner core, thus have sufficient space to deviate from outer core, be convenient in demoulding, do not damage ladle blank during the demoulding.
The ripple of outer wicking surface comprises concave convex texture, and ladle nozzle and the slag lining of corresponding preparation form concave convex texture, are conducive to increasing further pour steel contact area, improve ladle structural stability and service life.
4. core rod column assembly is few, simple in construction, and during use, dimensional stability is high, is arranged and fixed conveniently.
