Abstract
The utility model discloses a wheel hub casting die capable of eliminating shrink holes on the back of a spoke. The wheel hub casting die capable of eliminating shrink holes on the back of the spoke comprises an upper die, a bottom die and a side die, wherein the upper die, the bottom die and the side die defines a wheel hub cavity; the wheel hub cavity comprises more than two rib cavities; the upper die is provided with R angle bosses arranged between every two rib cavities at intervals; each R angle boss is internally provided with a ventilation pin, an air vent at one end of the ventilation pin faces towards the wheel hub cavity, and the ventilation pin is internally connected with a vent pipe; the vent pipe is provided with a closed end which is inserted into the ventilation pin and a vent end arranged outside the upper die. The wheel hub casting die capable of eliminating shrink holes on the back of the spoke has the advantages that the ventilation pin is arranged, so that gas at the R angle bosses inside the wheel hub cavity can be timely eliminated; the vent pipe is arranged, and cooling effect is optimized, so that heat can not be collected at the R angle bosses; cooling speed and time of molten aluminium are balanced with the cooling speed and time of the molten aluminium at other places when the molten aluminium at the R angle bosses is subjected to mould filling, so that formation of the shrink holes on the back of the cavity of the spoke of a wheel hub casting is avoided and structural strength and quality of a wheel hub are guaranteed.
Description
Technical field
The utility model relates to the wheel hub processing technique field, particularly a kind of wheel hub casting mould of eliminating the shrinkage cavity of the wheel hub back side.
Background technology
Existing wheel hub processing mode adopts casting or die casting usually, casting mould generally comprises patrix, bed die and Bian Mo, and the three surrounds a wheel hub die cavity, and patrix is mainly to the back of the body chamber profile effect moulding of wheel hub, bed die is to the positive profile effect moulding of wheel hub, and the limit mould is to wheel rim profile effect moulding.Wherein upwards be provided with the R angle lug boss that can stretch between per two spoke rib die cavities patrix week; This R angle lug boss also is the place that upper die mold is the thickest, amount of localized heat is concentrated, formed the heat energy-saving position of mould, not only aggravated the heat fatigue of mould, and the product position of its corresponding moulding also is thicker, the existence of heat energy-saving position can make hub cast produce thermal stress after solidifying, cause casting deformation, crackle etc.; Simultaneously, thermal center place aluminium liquid cooling but setting time and other place does not obviously wait, and loosening can appear in hub cast, cold shut, the defectives such as pore.And the thermal center effect of the R angle protuberance of patrix also just causes wheel hub product back of the body chamber profile very easily therefore to cause shrinkage cavity, has affected the quality of wheel hub product.
Summary of the invention
The technical problems to be solved in the utility model is, the mode of ventilation pin is set by employing, reducing the heat of patrix R angle lug boss concentrates, so that the temperature of patrix R angle lug boss and all the other everywhere equalized temperature and be easy to control, thereby elimination thermal center, the liquid cooling of balance aluminium is setting time but, avoids the generation of hub cast spoke back of the body chamber profile shrinkage cavity defect.
In order to address the above problem, the technical solution adopted in the utility model is specially: a kind of wheel hub casting mould of eliminating the shrinkage cavity of the spoke back side is characterized in that comprise patrix, bed die and Bian Mo, described patrix, bed die and Bian Mo surround a wheel hub die cavity; Comprise 2 above rib die cavities in the wheel hub die cavity; Has the R angle lug boss that is arranged at intervals between per two rib die cavities on the described patrix;
Lug boss inside, described R angle is provided with the ventilation pin, and ventilation pin one end blow vent is connected with ventilation duct towards the wheel hub die cavity in the ventilation pin;
Described ventilation duct has the blind end that stretches in the ventilation pin, and is positioned at the outer ventilating opening end of patrix.
Further, described ventilation duct is comprised of branch road ventilation duct and main ventilation pipe, and it is the ventilating opening end that the main ventilation pipe has an end at least, and is communicated to the patrix outside; The setting of main ventilation pipe is for the ease of access gas from the outside, to realize cooling effect;
Branch road ventilation duct one end seals not blind end, and is positioned at the ventilation pin, and the other end is communicated with the main ventilation pipe.The one end sealing of branch road ventilation duct can so that mould when realizing better cooling effect, can not make refrigerating gas pour into the wheel hub die cavity, cause the defective of foundry goods.By being set, the main ventilation pipe is connected with each branch road ventilation duct, and and then to be communicated with patrix outside, on the scavenging action basis of ventilation pin, the cooling effect of ventilation duct can better avoid the heat of patrix R angle lug boss to concentrate, and then the shrinkage cavity defect of avoiding heat energy-saving position to cause.
Further, in the above-mentioned patrix, be respectively equipped with 3 ventilation pins in each R angle lug boss, each ventilation duct blind end stretches into respectively in each ventilation pin.The quantity of ventilation pin can be adjusted according to the size of hub size, R angle lug boss etc., to realize better cooling effect.
Described main ventilation Guan Yiduan sealing, the other end is communicated to the patrix outside.
The beneficial effects of the utility model are: by the ventilation pin is set in the lug boss of patrix R angle, the gas at lug boss place, R angle can in time be got rid of in the realization wheel hub die cavity, ventilation duct is set simultaneously, optimize cooling effect, so that lug boss place, R angle does not assemble heat-collecting capacity, therefore just can not produce the thermal center effect yet.The aluminium liquid at lug boss place, R angle is when filling type, and its cooling velocity and time and other be balance everywhere, has so just avoided the generation of hub cast spoke back of the body chamber profile shrinkage cavity, for wheel hub structure intensity and quality provide guarantee.
