A kind of Cylinder Sleeve by Centrifugal Casting somatotype dividing plate
Technical field
The utility model relates to tool for casting, relates in particular to a kind of Cylinder Sleeve by Centrifugal Casting somatotype dividing plate.
Background technology
Current, it is high that centrifugal casting production revolving body has efficiency, percent defective is low, the advantages such as foundry goods dense structure, and adopt centrifugal casting at cylinder jacket production industry more, traditional handicraft is to cast out a foundry goods at every turn, production efficiency is lower, having now new technique is to carry out two liner blanks of single casting by improving casting mould, realize the two bases of a mould, although this technique has improved casting efficiency, but be connected to each other and leave large allowance between two blanks, add and also need man-hour two bases to be divided into two monomer blanks, operation and tool wear have been increased, casting cost and production time have been improved simultaneously.
Utility model content
In order to overcome above-mentioned defect, the utility model provide a kind of can single casting produce the Cylinder Sleeve by Centrifugal Casting somatotype dividing plate of two monomer blanks.
To achieve these goals, the technical solution of the utility model is: a kind of Cylinder Sleeve by Centrifugal Casting somatotype dividing plate, described somatotype dividing plate is circular, annulus external diameter is identical with casting outer mold internal diameter, internal radius is less than spray internal diameter 2-4mm, on the inner round wall of described somatotype dividing plate, is arranged with overflow launder.
Further, the degree of depth of described overflow launder is 6-10mm.
Further, the thickness of described somatotype dividing plate is 4-8mm.
Further, the quantity of described overflow launder is 2 or 4 or 8.
The beneficial effects of the utility model are: by the two mold tools of mould middle part, this novel somatotype dividing plate being set, can single water and cast out two monomer blanks, enhance productivity, reduce the production and processing time and reduce casting cost.

The specific embodiment
Below in conjunction with specific embodiment, the utility model is described further.
As shown in Fig. 1 Fig. 2, a kind of Cylinder Sleeve by Centrifugal Casting somatotype dividing plate, described somatotype dividing plate 1 is circular, annulus external diameter is identical with casting outer mold 2 internal diameters, as a kind of preferred version, internal radius is less than spray 3 internal diameter 2mm, on the inner round wall of described somatotype dividing plate 1, is arranged with overflow launder 4.
Further, as a kind of preferred version, the degree of depth of described overflow launder 4 is 8mm.
Further, as a kind of preferred version, the thickness of described somatotype dividing plate 1 is 4-8mm.
Further, as a kind of preferred version, the quantity of described overflow launder 4 is 4.
As shown in Figure 2, the specific works principle of the somatotype dividing plate 1 that this is novel is: Cylinder Sleeve by Centrifugal Casting mould comprises outer mold 2 and inner mold, inner mold is divided into front internal mold 5 and the rear internal mold 6 of symmetric design, during casting, outer mold 2 is interior first put into after internal mold 6, then put into somatotype dividing plate 1, then put into front internal mold 5, forward and backward internal mold 5,6 is clipped in the middle somatotype dividing plate 1; During casting, iron liquid enters in die cavity by tapping hole 7, while mold high speed centrifugal rotation, iron liquid is full of the overflow launder 4 by somatotype dividing plate 1 after front internal mold 5 and is full of whole die cavity, after casting, blank 3 is divided into two monomer blanks 3 by dividing plate, the middle tie point that only has four overflow launders 4 to form, is just knocked and can be separated by simple cutting or machinery.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical solution of the utility model, within all falling into protection domain of the present utility model.
