Description
Technical field
The utility model is related to aluminum-alloy wheel casting fields, more particularly to a kind of aluminum-alloy wheel low pressure casting water mist
Cooling mold.
Background technology
Low pressure casting be produce aluminum-alloy wheel most basic method, low pressure casting be by casting mold cavity be placed on one it is closed
Container above, liquid aluminium is filled in container, is connected to the molten aluminum in container with stalk below cavity.If in container
Liquid aluminum on the air with pressure is added, molten aluminum can flow into cavity from stalk, will be in container after molten aluminum solidification
Compressed air discharges, and not solidified molten aluminum is flow back into from stalk in container.Control flows into the pressure of container atmosphere, speed just
Speed and pressure that molten aluminum flows into cavity can be controlled, and can allow molten aluminum crystallization and freezing under stress.This process characteristic is
Casting crystallizes under stress, dense structure, good mechanical property；Another feature does not have to riser, cast gate yet very little.So metal
Utilization rate is high.
The front of wheel is decorative cover, general more demanding, it is desirable that finishing, the bright face of vehicle, polishing, plating, and low pressure is cast
Can just the front of wheel be placed on lower die by making, and near cast gate, finish is relatively good.
Aluminum alloy wheel of vehicle, wheel rim are uniform wall thickness, and area is bigger, and spoke is thicker, spoke and wheel rim junction
Thermal center is bigger.Three kinds of contractions can occur in process of setting for die casting：First, liquid volume contraction, molten aluminum are dropped by pouring temperature
To alloy liquidus temperature when the reduction in bulk that is occurred；Second is that the volume contraction in solidification period, i.e. liquid are consolidated and deposit period hair
Raw reduction in bulk；Third, solid-state volume is shunk, temperature is down to the reduction in bulk occurred when room temperature.
Only there are one small cast gates for the running gate system of aluminium wheels, and without riser, spoke is used as cross gate mostly, and molten aluminum is through cast gate
Spoke and other positions are flowed to, to ensure aluminum liquid filling type and consecutive solidification, will produce thermal center in the root of spoke；Secondly, core wheel
With spoke position since casting wall is thicker, temperature of aluminum liquid is higher, and degree of supercooling is relatively low, and die casting is shunk in process of setting to fail
To being replenished in time for liquid, to cause hole in irregular shape in tissue；Furthermore pack alloy hub for vehicle wheel finally coagulates
Gu it is easy to and shrinkage cavity and porosity occur since feeding is insufficient at final solidified position during consecutive solidification, cause tissue not
It is fine and close.It has been investigated that such defect generally occurs in the spoke, core wheel and wheel rim position of wheel hub,
Existing low-pressure casting die of aluminium alloy wheel substantially use air-cooled and Water Cooling Technology, existing cooling duct by
Then it is directly blown in mould inside, the process blown be easy to cause the shadow to adjacent spokes and wheel rim position due to there is the wind that rebounds
It rings, that is, causes adjacent area spoke Feeding channel to solidify in advance or wheel rim is locally loose causes airtight inspection gas leakage；Using air hose
Cooling method cooling is slow, and efficiency is low；Compressed air is of high cost；In addition air-cooled is open discharge, and noise is big.Water Cooling Technology is
Many water channels are processed in mold, intensity of cooling is big, it is difficult to it adjusts, is difficult to realize sequence cooling and gradient cooling, i.e., it is different
Position has different intensities of cooling.Therefore, need work one kind that can substitute air-cooled, water cooling, the fast intensity of cooling of cooling velocity is adjustable
The mold of aluminum-alloy wheel low pressure casting.
