Abstract
The utility model discloses a die of a reducer vertical base, which comprises an upper die plate and a lower die plate. The upper die plate comprises a core column, a boss is arranged on the outer side of the core column, and three vent holes are disposed on the boss. According to the die of the reducer vertical base, risers of prior dies are replaced by the vent holes so that not only a radiating function is achieved, but also shrinkage cavities at hot junction of forged vertical bases are reduced. A chiller is arranged so that the shrinkage cavities are further reduced, and service life of the vertical bases is prolonged.
Description
Technical field
The utility model belongs to a kind of casting mould, particularly a kind of reductor stand mould.
Background technology
Stand is the critical component of reductor, and is general through casting formation blank, and then forms finished product through machined.At present, employed casting mould is provided with rising head in the casting process, and rising head can play the effect of heat radiation, but but because the existence of rising head forms shrinkage cavity easily when punching at the thermojunction place of blank stand, has influenced the service life of stand.
Summary of the invention
The utility model provides a kind of reductor stand mould for solving the technical problem that exists in the known technology, and this mould can reduce the formation of stand thermojunction place's shrinkage cavity.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of reductor stand mould; Comprise cope match-plate pattern and lower bolster; Said cope match-plate pattern includes stem stem, and the arranged outside of said stem stem has boss, and said boss is provided with three ventholes.
The utility model can also adopt following technical scheme:
Said venthole is uniformly distributed on the boss.
Be provided with chill between said per two ventholes.
The diameter of said venthole 3 is 20mm.
Advantage and the good effect that the utlity model has are: venthole replaces the rising head in the original mould; Not only can play the effect of heat radiation, can also make the stand that casts out reduce shrinkage cavity, the setting of chill at the thermojunction place; Strengthen the minimizing of shrinkage cavity especially, improved the service life of stand.
Description of drawings
Fig. 1 is the utility model cope match-plate pattern vertical view;
Among Fig. 1: 1. stem stem, 2. boss, 3. venthole, 4. chill.
The specific embodiment
For further understanding utility model content, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, a kind of reductor stand mould comprises cope match-plate pattern and lower bolster; The center of cope match-plate pattern is provided with stem stem 1, to form the centre bore of stand, is boss 2 in the outside of stem stem 1; To form the flange of reductor stand, boss 2 is provided with three ventholes 3, and the diameter of venthole is 20mm; Venthole is uniformly distributed on the boss 2, between two ventholes 3, is provided with chill 4.
Venthole in the utility model replaces the rising head in the original mould, not only can play the effect of heat radiation, can also make the stand that casts out reduce shrinkage cavity at the thermojunction place, and the minimizing of shrinkage cavity has been strengthened in the setting of chill especially, has improved the service life of stand.
