Each corresponding through-hole of tool is equipped with loose piece and corresponding location structure, not only casting mould complicated integral structure, but also produce
Cast-internal fash it is more, influence product quality.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of casting mould of agricultural machinery differential casing, it can be effective
Existing casting mould complicated integral structure is solved, and the cast-internal fash produced is more, influences product quality.
Its technical solution is such, including upper sand mold, lower sand mold and sand core, the upper sand mold, the sand core and institute
State lower sand mold split formation casting mold cavity corresponding with agricultural machinery differential casing, it is characterised in that：The upper sand mold and it is described under
The die joint of sand mold is located at plane where the bottom wall of the straight slot of agricultural machinery differential casing；The sand core includes integrally formed molding
Portion and positioning region, the forming part include the first forming part and the second forming part for being distributed in the first forming part periphery, institute
State the first forming part offered with agricultural machinery differential casing straight slot inner edge surface it is corresponding, second forming part and agricultural machinery differential mechanism
The straight slot of housing is corresponding and quantity is identical.
Further, the upper sand mold includes upper molding protrusion, and the lower sand mold is equipped with lower molding protrusion, the upper molding
The entirety that raised, described sand core and the raised split of lower molding are formed is corresponding with the agricultural machinery differential carrier intracoelomic cavity.
Further, the positioning region include upper positioning region and lower positioning region, it is described it is upper molding protrusion be equipped with it is described on
The upper locating slot of positioning region cooperation, the lower molding protrusion are equipped with the lower locating slot with the lower positioning region cooperation.
Further, the lower positioning region is multidiameter structure.
