Abstract
The utility model provides a mould for casting a roll shaft and relates to a mould for casting, the mould for casting the roll shaft solves the problem of molten iron unevenly distributed cavity sugaring and slag inclusion easily causes by a sprue casting type casting roll shaft. The mould for casting the roll shaft comprises a cylindric die body, a lap of grooves are arranged in the upper surface of the die body, evenly distributed through holes are formed in the bottom portions of the grooves, a layer of refractory materials are arranged on the inner walls of the grooves, and two lifting rings are symmetrically arranged on the outer sides of the die body. The mould for casting the roll shaft is arranged on the top portions of roll shaft moulds as casting, thereby enabling the molten iron to enter inside of the roll shaft by the through hole, the molten iron is evenly distributed, thereby avoiding sugaring. Due to the fact that the molten iron enters inside the roll shaft mould by the through hole in the grooves, the slag of the molten iron floats at the upper portion of the grooves. So the mould for casting roll shaft can filter the slag and place slag inclusion.
Description
Technical field
The utility model relates to a kind of casting mould, specifically the mould used of a kind of roll shaft of casting.
Background technology
When producing roll shaft, the formula cast molding is directly watered in the general employing of roll shaft that especially diameter is larger at present, but adopts the method for direct pouring to cause easily the molten iron skewness, molten iron contains residue, direct pouring can not filter residue, makes the easy dusting of die cavity, slag inclusion, affects the quality of roll shaft.
The utility model content
The mould that provides a kind of roll shaft of casting to use is provided the purpose of this utility model, solves and directly waters the problem that formula casting roll shaft easily causes molten iron skewness die cavity dusting slag inclusion.
The technical scheme that its technical problem that solves the utility model adopts is: the mould that a kind of roll shaft of casting is used, it is characterized in that, comprise cylindric die body, the die body upper surface is provided with a circle groove, bottom portion of groove is provided with equally distributed through hole, be provided with one deck refractory material at the groove inwall, at two hoisting rings that are provided with of the outside of die body symmetry.
The beneficial effects of the utility model are: when casting, install this mould additional at roll shaft mould top, molten iron is entered in the roll shaft mould by through hole, molten iron is evenly distributed, avoid dusting, because molten iron enters the roll shaft mould by through hole in groove, the residue in the molten iron floats over groove top, can play the filter residue effect, place slag inclusion.
Description of drawings
Fig. 1 is cutaway view of the present utility model.
Among the figure: 1 die body, 2 grooves, 3 through holes, 4 refractory materials, 5 hoisting rings.
The specific embodiment
As shown in Figure 1, the mould that a kind of roll shaft of casting is used comprises cylindric die body 1, die body 1 upper surface is provided with a circle groove 2, and groove 2 bottoms are provided with equally distributed through hole 3, are provided with one deck refractory material 4 at groove 2 inwalls, at two hoisting rings 5 that are provided with of the outside of die body 1 symmetry, conveniently take.
During use, the utility model is placed on the roll shaft die tip, molten iron is poured in the groove 2 of die body 1, molten iron enters the roll shaft mould by groove 2 interior uniform through holes 3, so that the molten iron in the roll shaft is evenly distributed.Because the residue in the molten iron is floating state, therefore when molten iron enters the roll shaft mould, can also play the filter residue effect, avoid the phenomenon of dusting, slag inclusion, improved the quality of roll shaft.
