Technical field
The present invention relates to a kind of lower moldlocks, further relate to a kind of hub mold using the lower moldlock.
Background technique
Low pressure casting is the main forming technology of current aluminium alloy wheel hub of vehicle as a kind of precision casting forming technique.
Lower die is the component for forming wheel hub casting mold cavity, and the deformation in accurate to dimension and casting process can all influence wheel
The casting accuracy of hub.As shown in Figure 1, this is to use the wheel hub casting mould 100 of current relatively common structure, including be used to cast
The casting mold cavity 1 of wheel hub, the lower die 2 for surrounding the casting mold cavity 1 and the lower mold mounting plate for fixing the lower die 2
3.The middle section of the lower die 2 is provided with melt entrance 20, is provided with screw hole (by spiral shell in figure on its outer edge 21
Bolt 4 blocks, and is not marked), there is installation through-hole (to be blocked in figure by bolt 4, do not marked on the lower mold mounting plate 3
Note).The outer edge 21 of the lower die 2 is placed on the lower mold mounting plate 3, and bolt 4 passes through the peace on the lower mold mounting plate 3
It is installed in the screw hole that dress through-hole is connected in the lower die 2 to which the outer edge 21 of the lower die 2 is locked at the lower die
On plate 3.Application the wheel hub casting mould 100 production cast and in fill type and pressurization stages during, the casting
Type chamber 1 is in the condition of high temperature, and the temperature that the lower die wall body in 20 periphery of melt entrance of the lower die 2 is born is opposite
It is larger, temperature often up to 530 DEG C, cause in the axial direction (arrow F direction in figure) there is serious upward protuberance to become
Shape, and the deflection for being located at the outer edge 21 of the lower die 2 is minimum, this cause the dimensional accuracy of the manufactured wheel hub come out compared with
Difference, wheel hub material thickness ununiformity.
Summary of the invention
