Further, splitter cavity top arranged on left and right sides is equipped with first conical surface, first conical surface of the arranged on left and right sides
Opening is up-small and down-big.First conical surface makes aluminium bar aluminum melt preferably be sprayed to both sides.
Further, the shunting bridge cross section is up-side down triangle, so that the feeding mouth of middle tap hole is less than discharge port, accelerates
Aluminum melt jet velocity.
Further, the leading flank of the middle tap hole is set as second conical surface, and the feeding mouth of middle tap hole is made to be less than discharging
Mouthful, make in middle tap hole aluminum melt spray liquid flow at the bottom wall of workpiece.
Further, the third conical surface has been installed close to shunting bridge location on the left and right tap hole trailing flank, the third conical surface
It is up big and down small to locate longitudinal section tap hole aperture, and the aluminum melt in left and right tap hole is made to flow to the bottom wall of workpiece.
Further, the lower die workpiece shaping chamber lower part is equipped with level Four sky knife, which is 15-20mm.
The utility model has the beneficial effects that：Feeding mouth is equipped with front and rear sides cambered surface portion in upper mold splitter cavity, makes aluminum melt
Form chamber pressure injection effect, first and second, two conical surfaces make aluminum melt flow to the flow velocity of workpiece everywhere to tend to one to reducing mold
Crimp power improves mould structure intensity, reduces die boundary dimensions, and die cost is greatly saved and purchases large-scale squeeze
The expense of press.
