Abstract
The utility model provides a kind of aluminum-alloy wheel casting mould for being used to improve precasting nest casting reliability, and the mould includes upper mold, Bian Mo and lower die, it is characterised in that the side mould surrounds circlewise, and surrounds out cavity jointly with upper die and lower die；The upper mold includes through hole, and top stem casing is provided with through hole, and one end of mandril heads into top stem casing, and the other end is fixed to cope plate；Top stem casing pressing plate is covered in above top stem casing；The top stem casing lower edge is arranged to the upper model cavity lower surface of prominent mould, and top stem casing pressing plate and top stem casing are point contact, and gap is included between the top stem casing pressing plate and upper mold upper surface.By above technical scheme, thoroughly solve the problems, such as that top stem casing moves up caused by top stem casing does not press tightly, while also solve the problems, such as that the aluminium alloy wheel hub flange precasting nest depth dimensions that thereby results in is overproof.
Description
Technical field
Technical field of automobile parts is the utility model is related to, is used to improve the casting of precasting nest reliably more particularly to one kind
The aluminum-alloy wheel casting mould of property.
Background technology
Some aluminium alloy wheel hub of vehicle flange positions need to carry out precasting nest, therefore in mold design, it is necessary in a mold
The corresponding casting nest moulding of heart top stem casing position design, to meet product-forming demand.Top stem casing is fixed by pressing plate, because of height
Warm lower push rod set pressing plate has certain thermal deformation, therefore the top stem casing of a part has situation about not pressing tightly, and mandril is in recycling
During, it can drive top stem casing generation is certain to move up, cause precasting nest to shoal, seriously affect product-forming and precasting nest depth
Size, brings greater impact to production and product quality.
The content of the invention
Therefore, the purpose of this utility model is a kind of new mould structure of design to solve the problem in this industry.
In order to realize the goal of the invention of the above, the utility model provides following technical solution：
In the one side of the utility model, there is provided a kind of aluminum-alloy wheel for being used to improve precasting nest casting reliability
Casting mould, the mould include upper mold, Bian Mo and lower die, it is characterised in that and the side mould surrounds circlewise, and and
Upper die and lower die surround out cavity jointly；The upper mold includes through hole, and top stem casing, one end top of mandril are provided with through hole
Enter top stem casing, the other end is fixed to cope plate；Top stem casing pressing plate is covered in above top stem casing；The top stem casing lower edge is arranged to
The upper model cavity lower surface of prominent mould, top stem casing pressing plate and top stem casing are point contact, on the top stem casing pressing plate and upper mold
Include gap between surface.
Gap between the preferable aspect of the utility model, the top stem casing pressing plate and upper mold upper surface is 0.5-
3.5mm。
At the preferable aspect of the utility model, five groups of mandril is included in upper mold.
At the preferable aspect of the utility model, the top stem casing lower edge protrudes the upper model cavity lower surface 3-7mm of mould.
In terms of the utility model others, there is provided a kind of low-pressure casting hub die structure improved.
Before improvement, the top stem casing upper surface that is compacted with mould in the same plane, after top stem casing pressing plate has thermal deformation,
Have the situation that some positions do not press tightly.Top stem casing is designed to the structure of protrusion die surface, in this way, top stem casing pressing plate and mould
Tool has certain gap, and top stem casing pressing plate and top stem casing are point contact form, even if top stem casing pressing plate, which is heated, deformation, also may be used
To be in close contact with top stem casing, and compressed.
By above technical scheme, thoroughly solve the problems, such as that top stem casing moves up caused by top stem casing does not press tightly, while
Solve the problems, such as that the aluminium alloy wheel hub flange precasting nest depth dimensions that thereby results in is overproof.

Embodiment
Embodiment 1
Before improvement, the top stem casing upper surface that is compacted with mould in the same plane, after top stem casing pressing plate has thermal deformation,
Have the situation that some positions do not press tightly.Top stem casing is designed to the structure of protrusion die surface, in this way, top stem casing pressing plate and mould
Tool has certain gap, and top stem casing pressing plate and top stem casing are point contact form, even if top stem casing pressing plate, which is heated, deformation, also may be used
To be in close contact with top stem casing, and compressed.
In the present embodiment, there is provided a kind of aluminum-alloy wheel casting mould for being used to improve precasting nest casting reliability,
The mould includes upper mold, Bian Mo and lower die, it is characterised in that the side mould surrounds circlewise, and and upper die and lower die
Cavity is surrounded out jointly；The upper mold includes through hole, and top stem casing is provided with through hole, and one end of mandril heads into top stem casing,
The other end is fixed to cope plate；Top stem casing pressing plate is covered in above top stem casing；The top stem casing lower edge is arranged to prominent mould
Upper model cavity lower surface, top stem casing pressing plate and top stem casing are point contact, between the top stem casing pressing plate and upper mold upper surface
Including gap.Gap between the top stem casing pressing plate and upper mold upper surface is 0.75mm.Include five groups of top in upper mold
Bar.The top stem casing lower edge protrudes the upper model cavity lower surface 3-7mm of mould.
The results showed thoroughly solving the problems, such as that top stem casing moves up caused by top stem casing does not press tightly, while also solve
The problem of aluminium alloy wheel hub flange precasting nest depth dimensions thereby resulted in is overproof.
