Description
Technical field
The present invention relates to casting equipment fields, more particularly to a kind of piston casting equipment and its external mold.In addition, of the invention
Further relate to a kind of cooling means of above-mentioned piston casting equipment.
Background technique
Metallic piston is widely used in multiple fields, and piston blank shape is cylinder, and head wall thickness, skirt section wall is thin, tool
There is the characteristics of wall unevenness, generally poured by piston casting equipment and cast out piston blank, then piston blank passes through mechanical add again
The processes such as work, process piston finished product.
General piston casting equipment includes the components such as external mold, internal model, die cap, guide sleeve.Each component combination generate at
The mold cavity of type piston blank is provided with a running channel on external mold, and alloy solution enters mold cavity by running channel, then
Solidification forms piston blank.Wherein the contact area of external mold and piston blank is maximum, is that piston blank from liquid becomes solid
The most important component of piston blank Solidification Quality is determined on maximal heat transfer component, and entire mold.
The Temperature Distribution of external mold determines the heat-transfer effect to piston blank of external mold, and the uniformity of temperature profile of external mold is then right
The heat transfer cooling of piston blank is just uniform.For piston blank by heat transfer lowering temperature uniform, then piston metallographic structure is uniform, densification, refines,
The material property of piston is more preferably more consistent.
There was only two straight type water channels on existing mold external mold, when passing through cooling water in water channel to external mold cooling, due to straight
Type water channel is not to surround mold cavity circumference, therefore the temperature of external mold cannot be allowed equal around mold cavity circle distribution
It is even, so that the piston blank surrounding in external mold cannot be cooled down uniformly, it is cooling fast close to the blank position of water channel, far from water channel
Blank position it is cooling slow, cause the solidification of piston surrounding uneven, so that blank metallographic structure is uneven, piston performance is unstable
It is fixed.
And since metal is flowed into from external mold running channel, the temperature highest of external mold running channel peripheral location can be made, but external mold pours
The position in road is again farthest from cooling water channel, so that the temperature highest around mold runner, corresponding piston blank is solidifying herein
Gu it is also most slow, it is final solidified region, casting thermal center can be generated, to generates piston skirt shrinkage defect.Therefore, the prior art
It is not able to satisfy external mold to the Homogeneouslly-radiating demand of blank, the excessively high defect of running channel ambient temperature can not be solved, casting cannot be eliminated
Fabricate-heat section.
Therefore, how on the external mold of the non-uniform piston casting equipment of structure, realize that piston blank surrounding is uniformly quick
It is cooling, it is the current technical issues that need to address.
