Description
Technical field
The present invention relates to a kind of casing to cast sand mo(u)ld, more particularly to a kind of wheel side speed reducer casing casting sand mo(u)ld, belongs to car
Reductor field of components.
Background technology
Reductor is part important in vehicle, and reductor casing is the fully sheathed case of reductor, and it is more that casing is not only inside
Kind gear shaft support, and be the oil tank of multiple meshing gears, it is therefore desirable to reductor casing quality is hard, it is fine and close
Degree is high, and special requirement can not have the phenomenon of permeability and oil leak, once there is the phenomenon of permeability and oil leak, will mean
The possibility of traffic accident can occur, so, the requirement in manufacture to reductor casing is very high.
Reductor casing is usually that Fig. 3 is the structural scheme of mechanism of hub reduction casing using casting method manufacture, its
In, 11 be wheel side, and 12 be that reductor is shell inner chamber, 13 is bottom, 14 is bottom outlet.Fig. 4 is to utilize prior art cast reductor
The cross-sectional view of casing, wherein, 20 it is boss, 21 is that upper sand mold one, 22 is that lower sand mold one, 23 is core, 24 is core
Head, 25 be rising head, 26 be dreg collecting slot, 27 be sprue, in this cast structure, running gate system is arranged at wheel side speed reducer machine
The side of shell, centre are provided with core 23, and core 23 is fixed in top using core print 24, still, using this structure cast out come
Hub reduction casing 10 can produce the loose phenomenon of ring-type on wheel side 11 or the connecting portion periphery of bottom 13 and cavity wall, although the bottom of at
Chill is provided with portion and wheel side, is provided with rising head 25, loose phenomenon has been taken on a new look, but can not thoroughly be eliminated this loose thin
Hole phenomenon, particularly bottom, in the Drilling operation for carrying out gear shaft, usually occur, because of loose thin hole defect, to cause to process
During tool damage, broken drill, can also because inside loose thin hole reason, in boring procedure occur drill bit sideslip, lead
The generation for the problems such as causing inaccurate boring positioning, deflection of borehole, more important question is that because borehole circumference has loose phenomenon, casing
Interior machine oil can be along the outside oil leak of axis hole or permeability, and for the vehicles, this absolutely not allows, once leak
Oil or permeability must be scrapped, and how could eliminate this phenomenon, be a difficult problems of casing manufacturing firm.
The content of the invention
It can occur to take turns side or bottom in casting process for wheel side speed reducer casing and the connecting portion periphery of cavity wall produces
The loose phenomenon of ring-type can cause the problems such as inaccurate tool damage, broken drill, boring positioning, deflection of borehole, and the present invention provides one
Kind wheel side speed reducer casing casting sand mo(u)ld, the purpose is to overcome the loose thin hole defect in casting, realizes compact structure, avoids adding
Work is slipped up, and is prevented oil leak, permeability, is ensured the normal operation of vehicle.
The technical scheme is that：A kind of wheel side speed reducer casing casts sand mo(u)ld, including running gate system, its feature exist
In：The sand mo(u)ld includes sand mold and core, and sand mold includes upper sand mold and lower sand mold, and upper sand mold middle position below is provided with downwards
The cape of protrusion, core include upper core and lower core, and upper core is the cape being connected on sand mold, is provided with lower sand mold
Lower core and multiple chills, lower core are the overlay film sand core of built-in multiple blind risers, and lower core bottom surface is provided with boss, described
Core lid is provided with lower core in lower sand mold, the bottom center position of core lid is provided with protuberance, and core covers setting
There is air-vent, the chill is arranged on below the wheel side of wheel side speed reducer casing casting and on bottom of shell sand mo(u)ld, multiple dark
Rising head is 3-5, and multiple dreg collecting slots and a rising head, the upper sand mold and lower sand are provided with the cross gate of the running gate system
For the die joint of type on the upper surface horizontal plane on wheel side, the lower core is highly more than the 1/2 of reductor casing inner face height,
The blind riser upper opening is more than the sectional area of bottom.
The good effect that the present invention has is：By setting cape on upper sand mold, the volume of core, reduction type can be reduced
The weight of core, it is easy to the operation operation such as carrying；By the hollow shape core for by lower core being designed to that there are multiple blind risers, favorably
Annular loose problem in solution bottom, the consistency of casting can be improved；By in the wheel side bottom of reductor casing and machine
Shell bottom sets chill, can carry out Quench to molten iron, is advantageous to further reduce the loose thin hole phenomenon of annular, by using this
The core of structure carries out feeding to casting, can improve the consistency of casing, by covering setting passage in core, be advantageous to mend
The decline of intraoral molten iron is emitted in compression process, can be prevented due to air pressure deficiency, causes molten iron to decline slow phenomenon and occurs.By using
The sand mold and core of this structure, it can prevent casting from the loose thin hole of annular occurs, it is possible to increase the compactness of casting, to prevent
Phenomena such as Cutting Tool Damage, broken drill occur in process, prevented also from the skew of drilling, avoid oil leak, the permeability of casing
The problems such as appearance, it is ensured that the product quality of wheel side speed reducer casing.
