Abstract
The utility model relates to a special pouring basin for a precoated sand mold, which comprises a pouring basin body, wherein a precoated sand layer covers the inner wall of the pouring basin body, the thickness of the precoated sand layer is uniformly attached to the inner wall, grooves are arranged on two sides of the lower end of the outer wall, bulges are arranged on two sides of the lower end of the precoated sand layer, and filter sheets are erected on the bulges; because adhere to the intensity that the one deck tectorial membrane sand bed had guaranteed the pouring basin body on pouring basin inner wall, when preventing that the molten metal from pouring, the pouring basin body takes place to warp, erects the cassette in order to block partly impurity, is provided with the recess in the bottom, fixes the pouring basin on the mould for the convenience of using the binder, the utility model discloses pouring basin precision is high, has guaranteed pouring quality.
Description
Technical Field
The utility model relates to a pouring basin field of making especially relates to special pouring basin of tectorial membrane sand mould.
Background
The precoated sand mold has the advantages that the sprue cup is omitted when the precoated sand mold is used for pouring, the existing traditional technology uses green sand as a material to manually manufacture the sprue cup, however, the sprue cup is poor in surface quality, low in sand mold heat strength and easy to cause casting defects in the pouring process, slag cannot be effectively stopped, impurities are easy to flush into a cavity, and casting precision is affected.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a special pouring basin of tectorial membrane sand mould has solved the not high problem of current pouring basin intensity.
In order to achieve the above purpose, the utility model adopts the technical scheme that:
the utility model provides a special pouring basin of tectorial membrane sand mould, including pouring basin body, the inner wall of pouring basin body covers there is tectorial membrane sand bed, the even adhesion of tectorial membrane sand bed thickness is in on the inner wall, the outer wall lower extreme both sides of pouring basin body are provided with the recess, the lower extreme both sides of tectorial membrane sand bed all are provided with the arch, the protruding filter plate that has erect.
Further, the filter plate is a ceramic filter plate.
Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:
the utility model discloses a special pouring basin of tectorial membrane sand mould, because adhere to one deck tectorial membrane sand layer on pouring basin inner wall and guaranteed the intensity of pouring basin body, when preventing that the metal liquid from pouring, pouring basin body takes place to warp, erects the cassette in order to block partly impurity, is provided with the recess in the bottom, fixes the pouring basin on the mould for the convenience of use binder, the utility model discloses pouring basin precision is high, guarantees to pour the quality.
Drawings
Some specific embodiments of the present invention will be described in detail hereinafter, by way of illustration and not by way of limitation, with reference to the accompanying drawings. The same reference numbers in the drawings identify the same or similar elements or components. Those skilled in the art will appreciate that the drawings are not necessarily drawn to scale. In the drawings:
fig. 1 is a schematic structural diagram of a preferred embodiment of the present invention.
Wherein the reference numerals are as follows:
1. a pouring cup body; 2. coating a sand layer; 3. a protrusion; 4. a filter disc; 5. and (4) a groove.
Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
FIG. 1 is a schematic structural diagram of an embodiment of the present invention, the present invention includes a pouring cup body 1, a precoated sand layer 2 is uniformly attached to the inner wall of the pouring cup body 1 from top to bottom, the thickness of the added precoated sand layer 2 is about 5-16 mm, it is ensured that the shape of the pouring cup body 1 can not be changed even when the pouring cup body is subjected to a metal liquid with a higher temperature, a protrusion 3 is provided at the lower end of the precoated sand layer 2, a filter sheet 4 is hung on the protrusion 3, the filter sheet 4 is provided with uniform holes with a certain size, so as to avoid the liquid flow from directly rushing towards the pouring gate during pouring, thereby reducing the impact of the liquid flow on the casting, and also used for having a certain filtering function on the metal liquid poured into the cavity, the reason that the filter sheet 4 is made of ceramic material is that on one hand, the other hand, the ceramic material is economical, a groove 5 is provided at the connection part of the outer wall lower end of the, in order to bond the pouring cup body 1 on the mould by using the adhesive, the adhesive does not overflow to the upper surface of the mould, so that the mould is difficult to clean, and if the size of the pouring cup body 1 is smaller than the size of a pouring gate of the mould, other components can be used for being erected in the groove 5 and then bonded at the pouring gate.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
