Abstract
The utility model provides a camshaft mold modeling's chill structure, including mold modeling, be equipped with the camshaft casting pattern in the mold modeling, placed the chill in the cam position of camshaft casting pattern department, the both sides face of chill is equipped with the recess. Because the both sides face at the chill is equipped with the recess, adopts the utility model discloses on the sand mould made, form the exhaust passage between chill both sides and the sand mould, during the pouring exhaust of cam position unobstructed, carry high yield.
Description
Technical field
The utility model relates to the chill structure of camshaft manufacturing technology field, especially the camshaft moulding mould of automobile engine.
Background technology
The camshaft of automobile engine is ironcasting, and the cam position on it is more, and in casting process, cam position needs chill effect, and under this position, chill is realized conventionally. After moulding, between chill and sand mold, there is no exhaust passage, when cast cam position exhaust obstructed, easily cause gas hole defect, cause foundry goods to be scrapped.
Summary of the invention
The utility model proposes the chill structure of camshaft moulding mould, can improve the gas hole defect of one-piece camshaft, can ensure the yield rate of foundry goods.
For this reason, the technical solution of the utility model is: the chill structure of camshaft moulding mould, comprise moulding mould, and in moulding mould, be provided with camshaft casting pattern, cam position place at camshaft casting pattern is placed with chill, it is characterized in that: the two sides of chill are provided with groove.
Beneficial effect: because the two sides at chill are provided with groove, adopt on the sand mold of the utility model manufacture, form exhaust passage between chill both sides and sand mold, cam position smooth gas discharge when cast, improves yield rate.

Fig. 2 is side view of the present utility model.
Fig. 3 is the front view of chill in the utility model.
Fig. 4 is the side view of chill in the utility model.
Fig. 5 is the view at chill place in the sand mold manufactured of the utility model.
Detailed description of the invention
As shown in Figure 1, Figure 2, shown in Fig. 3 and Fig. 4, the chill structure of camshaft moulding mould, comprises moulding mould 1, is provided with camshaft casting pattern 2 in moulding mould, is placed with chill 3 at the cam position place of camshaft casting pattern, the two sides of chill are provided with groove 3-1.
As shown in Figure 5, owing to being provided with groove 3-1 in the two sides of chill 3, adopt on the sand mold of the utility model manufacture, between chill 3 both sides and sand mold 4, form exhaust passage B, cam position smooth gas discharge when cast, improves yield rate.
