Abstract
The utility model discloses the wheel pressure cooling duct of a kind of improvement, existing cylindrical straight mouth air-out pawl changes to the angle air-out pawl with certain angle, angle is set to 20 ° ~ 40 °.Cooling duct structure fabrication simple possible after this optimization, control the clearest and the most definite in casting cooling technique, effectively raise cooling duct intensity of cooling, the most preferably ensure that the consecutive solidification requirement of foundry goods, while obtaining castings, also improve production efficiency.
Description
Technical field
This utility model relates to a kind of wheel pressure casting field.
Background technology
The air-cooled technology of low pressure casting be wheel manufacturing enterprise widely used a kind of economical, simply, production technology flexibly,
Require it is necessary to be accurately controlled intensity of cooling and the cooling of cooling medium for realizing the consecutive solidification of foundry goods during wheel cast
Direction, the inside quality of final guarantee cast product.Owing to too strong intensity of cooling and incorrect cooling direction can be led
Cause foundry goods to realize consecutive solidification and produce defect waste product, therefore carry the cooling duct of two above key point, the most certainly
Determine cooling medium intensity of cooling and the process rationality in cooling direction.
Existing cooling duct structure does not has for wheel center, spoke root and wheel rim position, and position is divided in subregion
Set up to stand and reasonably cool down direction, also have to be strengthened simultaneously in terms of intensity of cooling.
Summary of the invention
In place of this utility model purpose is to solve and improve the deficiencies in the prior art, it is provided that a kind of cooling direction is clear and definite also
Intensity of cooling can be strengthened further and improve the cooling duct of production efficiency.
This utility model be the technical scheme is that the cooling duct of a kind of cold casting mould of aluminum vehicle wheel low-pressure air, will
Existing cylindrical straight mouth air-out pawl changes to the angle air-out pawl with certain angle, and angle is set to 20 ° ~ 40 °.
Diverse location and consecutive solidification for wheel require to determine the angle direction of air-out pawl.Cold to rim limit mould
But wind pawl is to avoid the feeding to top thin-walled wheel rim and temperature profile effect, and angle direction should down can at side wheel spoke root
More effectively realize the wheel rim consecutive solidification requirement to spoke root；To bed die cooling wind pawl at spoke root for avoiding adding high wind
Pawl intensity of cooling is to Feeding channel in the middle of spoke and temperature profile effect, and angle direction should be towards can be more effective at the outer rim of outside
Realize outer rim and arrive the consecutive solidification requirement on spoke flange inclined-plane to spoke root again；Backform at wheel disk and bed die are cooled down
Wind pawl is for avoiding adding high wind pawl intensity of cooling to Feeding channel in the middle of spoke and temperature profile effect, and angle direction should side wheel inwardly
Can more effectively realize arriving again to spoke flange inclined-plane in the middle of spoke the consecutive solidification requirement of core wheel at the heart.
Cooling duct structure fabrication simple possible after this optimization, casting cooling technique controls the clearest and the most definite, effectively
Improve cooling duct intensity of cooling, the most preferably ensure that the consecutive solidification requirement of foundry goods, while obtaining castings
Also improve production efficiency.
Accompanying drawing explanation
Fig. 1 is background technology former cooling duct structural plan.
Fig. 2 is cooling duct structural plan of the present utility model.
1. bed die in figure, 2. limit mould, 3. backform, 4. cooling duct A, 5. cooling duct B, 6. cooling duct C, 7.
Cooling duct D, 8. cooling duct E, 9. cooling duct F, 10. cooling duct G.
Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
This utility model cooling duct manufacture method is simple, is 30 ° by the angle angular dimension unification of air-out pawl.To wheel
The cylindrical straight mouth air-out pawl of the cooling duct 7 at original corresponding sides mould 2 air holes is changed to have the oblique of certain angle by Wang Chu
Mouth air-out pawl, angle is directed downward at side wheel spoke root and realizes the wheel rim consecutive solidification requirement to spoke root.
To at spoke root, the cylindrical straight mouth air-out pawl of the cooling duct 10 at original corresponding bed die 1 air holes is changed to
Having the angle air-out pawl of certain angle, angle direction should arrive spoke towards realizing outer rim at the outer rim of outside to spoke root again
The consecutive solidification requirement on flange inclined-plane.
To at wheel disk by the cooling duct A4 at original corresponding bed die 2, backform 3 air holes, cooling duct B5, cooling wind
Pipe C6, cooling duct E8, the cylindrical straight mouth air-out pawl of cooling duct F9 change to the angle air-out pawl with certain angle, tiltedly
Realize arriving again to spoke flange inclined-plane in the middle of spoke the consecutive solidification requirement of core wheel at the inwards core wheel of mouth direction.
Claims (2)
1. the cooling duct of the cold casting mould of aluminum vehicle wheel low-pressure air, it is characterised in that: by existing cylindrical straight mouth air-out pawl
Changing to the angle air-out pawl with certain angle, angle is set to 20 ° ~ 40 °.
The cooling duct of a kind of cold casting mould of aluminum vehicle wheel low-pressure air the most according to claim 1, it is characterised in that: angle
It is set to 30 °.
