Description
Technical Field
The utility model relates to a chiller structure, concretely relates to high-efficient chilled chiller is used in precision casting.
Background
In order to save cost and reduce part weight during use and design of the existing precision casting, a plurality of isolated small heat nodes are arranged on the wall thickness, the internal quality requirement of the casting is high, and the main measures of the existing casting process are as follows: 1. a sprue is arranged at an isolated small hot node, so that the casting process yield is reduced sharply; 2. the patch is added to lead out isolated small thermal nodes, the patch removing efficiency in the finishing process is low, and the labor intensity is improved; 3. when in pouring, the cold iron is inserted into the isolated small hot node, so that the tail end area is rapidly cooled, and the common cold iron is poured into the high-temperature mould shell to be rapidly heated because the precision casting mould shell is a hot shell, so that the cooling effect is not obvious, the leakage phenomenon is generated during pressure testing, and the process is unstable. Secondly, after the molten metal is poured into the mold, the molten metal on the chilling surface begins to solidify under the action of chilling, and because the solidification time is too fast, gas in the molten metal lacks enough escape time, so that a plurality of bubbles are remained in the chilling layer, and pore defects are formed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a chill of high-efficient chilling is used in precision casting, its cooling effect is good, has improved casting process yield and foundry goods quality.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a chill of smart casting with high-efficient chilling, includes chill, steel sheet, the standing groove has been seted up on the chill lateral wall, it is equipped with annular flange just to be located the standing groove open end on the chill lateral wall, the chill is the integrated into one piece structure with annular flange, the steel sheet is provided with four, four the steel sheet encloses into and places the container, it is equipped with side opening and upper shed to place the container, it fixes at the standing groove open end to place the container, and the side opening is relative with the standing groove open end, it constitutes one with the standing groove and places the chamber to place the container, it places the ice cube to place the intracavity.
Preferably, the placing container is of an integrally formed structure.
Preferably, the thickness of the steel plate is 1.5 mm.
Preferably, the upper end face of the chilling block is provided with honeycomb holes.
Preferably, the surface of the chilling block, which is used for contacting with the casting, is provided with a sand layer, and the surface of the sand layer is provided with a graphite coating.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a placing the intracavity and placing the ice-cube, helping the quick cooling solidification of the isolated little hot spot of foundry goods, making the foundry goods quality more stable. Secondly, through setting up honeycomb holes, make things convenient for gaseous effective discharge, through setting up sand bed, graphite coating, reducible metal liquid prevents to form the bubble defect with the direct contact of chill.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. 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.
Referring to fig. 1-3, a high-efficiency chilled chiller 1 for precision casting comprises a chiller 1 and a steel plate 2, wherein a placing groove 3 is formed in the side wall of the chiller 1, an annular flange 4 is arranged on the side wall of the chiller 1 and at the opening end of the placing groove 3, and the chiller 1 and the annular flange 4 are of an integrally formed structure. The steel sheet 2 is provided with four, and the thickness of steel sheet 2 is 1.5mm, and four steel sheets 2 enclose into and place container 5, place container 5 and be the integrated into one piece structure, place container 5 and be equipped with side opening 6 and upper shed 7, place container 5 and fix at the 3 open ends of standing groove, and side opening 6 is relative with the 3 open ends of standing groove, places container 5 and standing groove 3 and constitutes one and place chamber 8, places and has placed broken ice cube 9 in the chamber 8. Honeycomb holes 10 are formed in the upper end face of the chilling block 1, a sand layer 11 is arranged on the surface, used for being in contact with a casting, of the chilling block 1, and a graphite coating 12 is arranged on the surface of the sand layer 11.
The working principle is as follows: for the mould shell needing to be inserted with the chilling blocks, the chilling blocks 1 with high efficiency are inserted before casting, and the crushed ice blocks 9 are filled in the placing cavity 8, so that the temperature can be quickly reduced; the honeycomb holes 10 are arranged, so that gas can be effectively discharged; the sand layer 11 and the graphite coating 12 can reduce the direct contact of the molten metal and the chilling block 1, and prevent the formation of bubble defects.
The foregoing is merely exemplary and illustrative of the structure of the invention, and various modifications, additions and substitutions as described in the detailed description may be made by those skilled in the art without departing from the structure or scope of the invention as defined in the accompanying claims.
