Abstract
The utility model is related to machine casting technical field more particularly to a kind of casting system of automobile differential housing, including：Running gate system, casting and sand core and sand mold chamber；It is characterized in that：The running gate system sets at least one ingate, and the end of the ingate is connect with sand mold chamber；The sand mold intracavitary sets sand core, and at least one runner system is equipped in the sand core；The runner system includes riser, insulating and heating riser set and riser neck；Insulating and heating riser set is nested with outside the riser, the insulating and heating riser set is Nian Jie with sand core；The riser also has at least one hollow riser neck.The setting that this casting system not only replaces sand riser by exothermic riser sleeve and riser reduces casting cost；Meanwhile more accurate feeding is not only realized by the setting of riser neck, and reduce the disposal costs after the completion of casting.
Description
Technical field
The utility model is related to machine casting technical field more particularly to a kind of casting systems for automobile differential housing
System.
Background technology
Structure diagram of the attached drawing 1 for the structure diagram, as automobile differential housing of casting；Automobile differential is to drive
The main part of dynamic bridge, its effect are exactly while to both sides semiaxis passing power, and both sides semiaxis is allowed to be revolved with different rotating speeds
Turn, meet two sidecar wheels and make Unequal distance traveling in the form of pure rolling as far as possible, reduce the friction on tire and ground；Differential carrier
Body is the main body of differential mechanism, and effect is as follows:Dispose cross axle or a word horizontal axis；It can keep differential mechanism and rear bridge driven wheel
It is constant to be driven axis；Torque is gone out by differential drive.Due to differential mechanism casing structure complexity, isolated thermal center point is more, material
Matter is spheroidal graphite cast-iron, and shrinkage porosite tendency is relatively also bigger, however the traditional handicraft of Foundry Production is using horizontal mo(u)lding line now
Or vertical modeling line production, feeding is carried out to casting using multiple sand riser, the product yield of casting substantially exists
40% or so, casting cost is higher.
Utility model content
In view of this, the purpose of this utility model is to provide it is a kind of it is simple in structure, be capable of significant increase production efficiency
The casting system of automobile differential housing.
In order to achieve the above objectives, the utility model provides following technical solution：A kind of casting system of automobile differential housing
System, including：Running gate system, casting and sand core and sand mold chamber；It is characterized in that：It is poured in the running gate system setting is at least one
Mouthful, the end of the ingate is connect with sand mold chamber；The sand mold intracavitary sets sand core, and at least one emit is equipped in the sand core
Port system；The runner system includes riser, insulating and heating riser set and riser neck；Heat retaining and exothermal is nested with outside the riser to emit
Muzzle, the insulating and heating riser set are Nian Jie with sand core；The riser also has at least one hollow riser neck.
The benefit of above-mentioned setting is：The setting realization of multiple sand mold chambers is connected by ingate while multiple casting are poured
Foundry work fills；By setting the setting of exothermic riser sleeve in sand core, realize at the shrinkage porosite stage of casting, in exothermic riser sleeve
Metal be also in a liquid state, can preferably to casting carry out feeding so that feeding efficiency can be to 35%；And by setting riser
Neck can realize that easy shrinkage porosite position carries out accurate fixed point feeding to casting；Simultaneously by arranging that a fever emits in sand core
The setting of muzzle and riser being capable of less sand core sand amount；And riser neck is after final be cooled and shaped, it can be by simple and quick
Cleaning reduces the cost of casting cleaning；Certainly, pass through the less original sand riser of the setting of exothermic riser sleeve and riser
Use, saved casting cost.
Further, there is one layer of anti-stick coating outside the sand core.
Further, the anti-stick coating is the anti-sticking sand coating of casting water base.
The beneficial effects of the utility model are compared with prior art：This casting system not only passes through insulating and heating riser
The setting that set and riser replace sand riser reduces casting cost；Meanwhile it is not only realized more accurately by the setting of riser neck
Feeding, and reduce the disposal costs after the completion of casting.

Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
It can be better understood from the utility model and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
With reference to attached drawing 1, a kind of casting system of automobile differential housing, including：3 and of running gate system 1, casting 2 and sand core
Sand mold chamber 6；The running gate system 1 sets at least one ingate 8, and the end of the ingate is connect with sand mold chamber 6；The sand
Setting sand core 3 in cavity 6, the sand core is interior to be equipped at least one runner system；The runner system includes riser 5, heat preservation hair
Hot riser set 4 and riser neck 7；Insulating and heating riser set 4, the insulating and heating riser set 4 and sand core are nested with outside the riser 5
3 bondings；The riser 5 also has at least one hollow riser neck 7.
Preferably, there is one layer of anti-stick coating outside the sand core 3.
Preferably, the anti-stick coating is the anti-sticking sand coating of casting water base.
Embodiment described above is only the preferred embodiment lifted to absolutely prove the utility model, the utility model
Protection domain it is without being limited thereto.The equivalent substitute or change that those skilled in the art are made on the basis of the utility model
It changes, is within the protection scope of the utility model.The scope of protection of the utility model is subject to claims.
