In Fig. 1 shown in (11)), the strength of materials is promoted by thickening blank, but but significantly increases disappearing for metal material in this way
Consumption, improves subsequent machining cost, reduces the productive profit of enterprise.
Utility model content
Therefore, the purpose of this utility model is to provide a kind of aluminum-alloy wheel low pressure casting blank with weight loss effect,
The aluminum-alloy wheel low pressure casting blank includes center flange disk, spoke, inner rim, wheel rim, outer rim, the center
Extend outwardly around ring flange and be connected with spoke, spoke end includes the outer rim of annular；Spoke, outer rim and center flange disk
Between limit window；The direction at outer rim towards the spoke back side includes the wheel rim of cartridge type, and the end of wheel rim includes inner rim；
Outer rim is towards on the direction of inner rim, and wheel rim is in the bcad seats that the position for closing on outer rim includes protrusion, it is characterised in that：Institute
The aluminum-alloy wheel low pressure casting blank stated has first at the window position that spoke, outer rim and center flange disk surround out
The allowance of thickness, the aluminum-alloy wheel low pressure casting blank bcad seats position have second thickness processing more than
Amount, the aluminum-alloy wheel low pressure casting blank has the allowance of third thickness in remaining position of spoke, described
Outer rim has edge line outstanding on the positive surface of wheel disc, and the edge line is outwardly protruded in the window's position, described
The allowance of first thickness is maximum, and the allowance of second thickness takes second place, and the allowance of third thickness is minimum.
It is 3-5mm, the processing of second thickness in the allowance of the preferred aspect of the utility model, the first thickness
Surplus is 2-4mm, and the allowance of third thickness is 1.2-2.4mm.
It is 4.2mm, the processing of second thickness in the allowance of the preferred aspect of the utility model, the first thickness
Surplus is 3.2mm, and the allowance of third thickness is 1.8mm.
At the preferred aspect of the utility model, the edge line is located at outer rim in the positive table of wheel disc in the window's position
At the 50-60% distances of face from inside to outside, and it is located at outer rim on the positive surface of wheel disc from inside to outside in non-the window's position
At 20-35% distances.
At the preferred aspect of the utility model, the edge line is located at outer rim in the positive table of wheel disc in the window's position
At 55% distance of face from inside to outside, and non-the window's position be located at outer rim the positive surface of wheel disc from inside to outside 28%
At distance.
Corresponding to the window's position, blank processing capacity designs bigger than normal, to minimize casting deflection
The utility model is skillfully constructed, simple in structure, it is contemplated that the modeling characteristic of wheel product, by the hair at bcad seats position
Base amount has carried out segment design, i.e. the window's position is thick, and spoke position is partially thinner, to effectively realize blank loss of weight, carries
High rate of metal, reduces raw material and subsequent machining cost；The face deformation amount of novel blank also becomes more uniformly,
Casting forming precision is improved, the high quality of production of wheel is realized.
Description of the drawings
Hereinafter, carry out the embodiment that the present invention will be described in detail in conjunction with attached drawing, wherein：
Fig. 1 is low pressure casting wheel blank schematic cross-section in the prior art；
Fig. 2 is improved low pressure casting wheel blank schematic cross-section in the present invention；
Fig. 3 is wheel blanks structure top view in the present invention；
In figure：11- bcad seats A, 1- inner rim, 2- wheel rims, blanking wire at 3- bcad seats B, 31- spoke, 32-

Specific implementation mode
Embodiment 1
Fig. 2,3 disclose the low pressure casting wheel blank that the utility model improves, including inner rim (1), wheel rim (2),
Bcad seats (3), outer rim (4), spoke (5), window (6)；Wherein bcad seats (3) position is the main of realization wheel blanks loss of weight
Region；The blank processing capacity at bcad seats (3) position segment design has been subjected to；The corresponding position of spoke (5) is partially thick, blanking wire
(31) it is designed by with type, gives minimum process amount；And the corresponding region of window (6) is partially thinner, therefore blank processing capacity
(32) need designed are bigger than normal, to minimize deflection, ensure casting front precision；(31) to ensure between (32) round and smooth
