Dress, finally, left sand mold 5 are assembled by positioning and guiding slot ecto-entad, form sand mold group, and group type feature is to be determined by sand mold
The four-way ecto-entad group type of position guide groove, sand mold self orientation, automatic positioning, group type are accurate.
Then, cylinder holes water jacket sand mold 7 falls the corresponding sand in interim sand mold group by the round core print position of itself, peace
On type direction and location, and across the cylinder holes shape of integral type chassis sand mold 1, form compound cylinder cap cylinder holes shape.Compound cylinder cap
Cylinder holes water jacket sand mold is maintained at vertical posture (i.e. straight diesel cylinder holes working condition) in casting mold, the benefit of this posture
It is：It is easy to observe the gap (wall thickness for being equivalent to casting) between sand mold in group type, the gap between sand mold can be adjusted in time,
It is easier to ensure the uniform wall thickness between casting cylinder holes.Moreover, cylinder holes shape in cylinder holes water jacket sand mold in casting with
The projected area in gravity direction of molten metal is minimum, therefore by the buoyancy of molten metal minimum, so the change of cylinder holes water jacket sand mold
Shape is minimum, the cylinder holes better quality of compound cylinder cap.
Then, combination sand mold 8 passes through the rectangular positioning key stacking group type on rear sand mold 3, right sand mold 4, left sand mold 5, combination
The oblong core print of air intake duct, exhaust duct on sand mold 8 and the core print position of the cylinder holes shape on integral type chassis sand mold 1 are matched closely
It closes, remaining core print position is worked good successively, completes the group type of combination sand mold 8 (referring to Figure 11 and Figure 14).
Then, shrouding disc sand mold 10 is by combining the rectangular positioning key stacking group type on sand mold 8.
Finally, casting sand mould 9 is developed with shrouding disc sand mold 10, and before being located on sand mold 2 and with the sprue hole of preceding sand mold 2
Alignment.
To sum up, the sand core group for casting integrated form Composite cylinder lid of the present embodiment, by integral type chassis, four-way is closed
Type combines sand mold, successively organizes the entire sand mold that assembles of mode of core so that the cylinder holes water jacket sand mold of integrated form Composite cylinder lid with
Vertical posture (i.e. straight diesel cylinder holes working condition) is maintained in casting mold, is easily obtained uniform wall thickness and is deformed small cylinder
Hole shape combines a variety of sand cores of the application integration of sand mold, simplifies group type technique and group type number, and group type is simpler accurate,
Air intake duct, exhaust duct will not float in casting process, and evenly, air port performance is more excellent for air intake duct, exhaust duct wall thickness.
The description of the aforementioned specific exemplary embodiment to the present invention is in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to the above instruction, can much be changed
And variation.The purpose of selecting and describing the exemplary embodiment is that explaining the specific principle of the present invention and its actually answering
With so that those skilled in the art can realize and utilize the present invention a variety of different exemplary implementation schemes and
Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
