Abstract
The utility model discloses a lower die structure of a centrifugal casting die, which comprises a lower die main body and an inner ring, wherein the inner ring is movably arranged inside the main body, a gap is arranged between the main body and the inner ring, i.e. the main body and the inner ring are of two independent parts, and the inner ring suffers less restriction of the main body when expanding with heat and contracting with cold. The lower die structure effectively prevents the crack and prolongs the service life of the die.
Description
Technical field
The utility model relates to casting mould, especially relates to the following mode structure of centrifugal casting mould.
Background technology
The centrifugal casting counterdie is an overall structure, and in process of production, counterdie is subjected to the influence of metal liquid heat conduction, its temperature also constantly increases, since interior ring heating surface area maximum, and its material entities is less, and therefore interior ring is more high than counterdie calor innatus expansion rate.After casting finished, mould was in the nature cooling, and interior ring area of dissipation is bigger, was easy to cooling and shrank.Because down mould body and interior ring are structure as a whole, long-term like this colding and heat succeed each other, weak part (interior ring) is the easiest cracks because of tired, reduces the service life of mould.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of counterdie of the centrifugal casting mould that is difficult for cracking is provided.
To achieve these goals, the technical solution of the utility model is:
A kind of following mode structure of centrifugal casting mould, comprise mould body and interior ring down, described inner ring sleeve is connected in the body, there is the gap between described body and the interior ring, be that body and interior ring are two independent parts, interior ring is subjected to body when expanding with heat and contract with cold constraint is less, effectively prevents the generation of crackle.
Because interior ring is heated, dilation dimension on the diametric(al) is between 0.1～0.4 millimeter, so in the technique scheme, the gap width of described body and interior ring is between 0.1～0.4 millimeter, most preferably described gap is 0.3 millimeter, like this mould in whole process of production no matter in the ring expanded by heating still cool off contraction, not restricted by other positions, effectively improved die life.
The utility model adopts technique scheme, obtains following beneficial effect:
The counterdie of casting mould of the present utility model, body and interior ring are set to independent parts, reduce the influence of the effect of expanding with heat and contract with cold to counterdie, and ring is difficult for cracking in making, has improved the service life of mould.
Description of drawings
Fig. 1 is the structure chart of the utility model centrifugal casting lower mould.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Shown in Figure 1, a kind of following mode structure of centrifugal casting mould comprises mould body 1 and the interior ring 3 that is socketed in the body 1 down, has gap 5 between body 1 and the interior ring 3, interior ring 3 can separate with body 1, be that body 1 is two independent parts with interior ring 3, in process of production, the counterdie heating temperature raises, interior ring 3 expanded by heating, owing to have gap 5 between interior ring 3 and the body 1, encircling 3 in when expanding with heat and contract with cold, to be subjected to the constraint of body 1 less, effectively prevents the generation of crackle.
Because interior ring 3 is heated, the size that expands on the diametric(al) is between 0.1～0.4 millimeter, and as preferably, the width in the gap 5 of body 1 and interior ring 3 is between 0.1～0.4 millimeter.
In actual production, the width in the gap 5 between body 1 and the interior ring 3 is decided to be 0.3 millimeter, like this mould in whole process of production no matter in ring 3 expanded by heating still cool off contraction, in certain scope, not restricted by other positions, effectively improve die life.
Claims (3)
1. the following mode structure of a centrifugal casting mould comprises mould body (1) and interior ring (3) down, it is characterized in that described interior ring (3) is socketed in the body (1), has gap (5) between described body (1) and the interior ring (3).
2. the following mode structure of a kind of centrifugal casting mould according to claim 1 is characterized in that, the width of described gap (5) is between 0.1 millimeter and 0.4 millimeter.
3. the following mode structure of a kind of centrifugal casting mould according to claim 1 and 2 is characterized in that, described gap (5) are 0.3 millimeter.
