Abstract
The utility model discloses a wheel hub die with a water mist cooling structure. The wheel hub die comprises an upper die (1), a lower die (3), a side die (4) and a base (2), wherein the upper die (1), the lower die (3) and the side die (4) are combined to form a casing die cavity of the wheel hub to be cast; an area formed by junction positions of the upper die, the lower die and the side die is a hot node (6) for casting the wheel hub; a water mist pipeline (7) is fixedly arranged on the side die and is provided with a water inlet mist port (7.2) connected with the outside; and a plurality of water mist spray heads (7.1) which point to the positions of the outer wall of the side die (4), which correspond to the hot node, are arranged at the tail end of the water mist pipeline (7). The water mist cooling structure is arranged at the position of the hot node, so that the cooling speed at the position is increased, the defects of shrinking or loosening are effectively overcome, the rejection rate of products is reduced and the production efficiency is increased.
Description
Technical field
The utility model relates to the machine casting technical field, specifically is a kind of hub mold that has the water smoke cooling structure.
Background technology
Wheel hub is as one of most important moving component of automobile, and to its performance, weight all has very high requirement service life.At present, aluminium alloy wheel hub is shown one's talent in auto industry with its light weight, rapid heat dissipation, advantage such as damping performance is good, the life-span is long, balance is good.
Aluminium alloy wheel hub generally adopts the mode of casting to produce; The mould that is used for casting hub mainly comprises mold, bed die, side mold and base; After said mold, bed die and the side mold combination; The casting mold cavity of casting hub is treated in formation, and described bed die and side mold all are fixed on the base.During cast, from the sprue gate charging that is positioned on the bed die die cavity is filled, in the process of setting after cast; The formed zone of the intersection of mold, bed die and side mold is the thermal center point of casting hub, and with regard to the structure of wheel hub, above-mentioned thermal center point is meant that handing-over intermediate location between spoke and the wheel rim is (because wheel hub is generally circle; This intermediate location is an annulus just also; The intermediate location that is full annular is the thermal center point), the wall thickness at this position is thicker, and cast back cooling velocity is slower; The spoke that is adjacent and the wall thickness of wheel rim are then thinner relatively; Cooling velocity is very fast, so locate to such an extent that be prone to produce shrinkage cavity, defective such as loose on the wheel hub spray at this, influences wheel hub spray quality.
The utility model content
The technical problem that the utility model will solve is, a kind of water smoke cooling structure of avoiding above-mentioned thermal center point place a kind of hub mold of shrinkage cavity or defective such as loose to occur is provided.
For solving above-mentioned technical problem; A kind of hub mold that has the water smoke cooling structure of the utility model comprises mold, bed die, side mold and base, after said mold, bed die and the side mold combination; The casting mold cavity of casting hub is treated in formation; Described bed die and side mold all are fixed on the base, and the zone that the position, boundary of said mold, bed die and side mold forms is the thermal center point of casting hub, is fixed with the water smoke pipeline on the said side mold; Said water smoke pipeline is provided with and the extraneous water inlet mist mouth of connecting, and said water smoke pipeline end is provided with and points to a plurality of waterfog heads of side mold outer wall corresponding to thermal center point position.
It is and the corresponding position of the spoke of treating the casting hub spoke that described waterfog head quantity is corresponding one by one with the quantity of spoke corresponding to thermal center point position that described waterfog head points to the side mold outer wall.
Said and the corresponding position of spoke is and the corresponding position of spoke end.
After adopting said structure; The utlity model has following advantage: through adopting the water smoke cooling structure is set, thermal center point position cooling velocity is accelerated, effectively avoided thermal center point place shrinkage cavity or defective such as loose to occur in thermal center point position; The product percent defective is reduced, and then improved production efficiency.
As improvement, waterfog head position pointed is provided with the radial groove that is used to strengthen cooling effect on the said side mold outer wall.Groove is set this place is cooled off more easily, better avoided thermal center point place shrinkage cavity or defective such as loose to occur.
As improvement, the periphery of waterfog head position pointed is provided with the baffle plate that is used to strengthen cooling effect on the said side mold outer wall; Described baffle plate is to be arranged on the waterfog head overhead gage and the lower baffle plate of both sides up and down.After baffle plate is set, make the cooling position more concentrated, cooling effect is better.
