Description
Technical field
The utility model belongs to Low Pressure Casting Technology field, is to be related to a kind of low pressure casting aluminum alloy vehicle more specifically
Wheel metal die.
Background technology
The aluminum-alloy wheel of domestic production at present mostly uses low pressure casting mode, will produce in low pressure casting cavity filling process
Stronger casting pressure, the molten aluminum in extrusion die form irregular zigzag by gap overflow at die joint after cooling
Overlap.In process of production, irregular overlap can be such that the utilization rate of raw material reduces, and increase production cost.
Utility model content
The purpose of this utility model is to provide a kind of pressure cast aluminum-alloy wheel metal dies, it is intended to solve existing
The problem of easy ting produce irregular overlap at die joint when technology mesolow cast aluminum alloy wheel, the present apparatus can realize reduction not
The problem of regular overlap.
To achieve the above object, the technical solution adopted in the utility model is：A kind of pressure cast aluminum-alloy wheel is provided
With metal die, including upper die and lower die, it is equipped with and is used in the edge of upper mold die joint with the overlapping region of lower die die joint
Accommodate the flash gutters of aluminium alloy.
Further, edge is at the die joint of upper mold and/or at the die joint of lower die.
Further, the cross-sectional shape of flash gutters is recessed U-shaped, flash gutters and the die joint being set at die joint
It is connected smoothly, overlap trench bottom is equipped with fillet, and flash gutters are directly connected to casting cavity.
Further, the cross section groove width of flash gutters is 3mm-6mm, groove depth 0.6mm-1mm.
Further, the cross-sectional shape of flash gutters is with the arc for removing corner angle tip.
Further, arc radius 0.6mm-1mm.
The advantageous effect of pressure cast aluminum-alloy wheel provided by the utility model metal die is：With the prior art
It compares, flash gutters are arranged in the upper mold edge for abutting region Chong Die with lower die die joint in the present apparatus, and the molten metal of overflow is retained
In in flash gutters and it is cooling fix, realize the purpose for reducing irregular overlap.

It please refers to Fig.1 and Fig. 2, now pressure cast aluminum-alloy wheel provided by the utility model is said with metal die
It is bright.Pressure cast aluminum-alloy wheel metal die, including upper mold 1 and lower die 2, in 1 die joint of upper mold and 2 die joint of lower die
The edge of overlapping region is equipped with the flash gutters for accommodating aluminium alloy.
Compared with prior art, the present apparatus is in the edge setting and casting for abutting region Chong Die with 2 die joint of lower die of upper mold 1
The molten metal of the flash gutters that part cavity is directly connected to, overflow resides in flash gutters and cooling fixation, cooling velocity are more than casting
The speed of cavity inner metal liquid first cools down fixed metal in flash gutters and effectively reduces irregular overlap.
Edge is at the die joint of upper mold 1 and/or at the die joint of lower die 2.Flash gutters may be provided at 1 up or down of upper mold
It is arranged in upper mold 1 and lower die 2 on mould 2 or simultaneously, the utility model does not limit the installation position of flash gutters.
The cross-sectional shape of flash gutters is to be set to recessed U-shaped at die joint, and flash gutters are seamlessly transitted with die joint
Connection, overlap trench bottom are equipped with fillet, and flash gutters are directly connected to casting cavity.
The cross section groove width of flash gutters is 3mm-6mm, groove depth 0.6mm-1mm.
The cross-sectional shape of flash gutters is with the arc for removing corner angle tip.
Arc radius is 0.6mm-1mm.
Low pressure casting aluminum alloy mold includes upper mold 1, lower die 2, Bian Mo and frame, the wherein die joint of upper mold 1 and lower die 2
The case where edge of overlapping region has face to be contacted with corner angle, corner angle and corner angle contact, in face and corner angle or corner angle and corner angle
In the case of contact, flash gutters on face or edges and corners can be set to according to actual conditions or be arranged simultaneously on the whole with edges and corners,
It is selected according to actual conditions.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
