Abstract
The utility model discloses a lower die for a novel cast-aluminum rotor die-casting mold. The lower die comprises a lower die body, wherein the lower die body is fixedly arranged in a lower die outer sleeve; the lower die body and the lower die outer sleeve are arranged on a base plate; an annular cavity corresponding to a cast-aluminum rotor is formed on the lower die body; a downsprue which passes through the base plate and the lower die body is formed on the lower die; a cross gate and a flow gate are formed on the lower die body; the downsprue sequentially passes through the cross gate and the flow gate to be communicated with the annular cavity; and the downsprue is coaxial with the annular cavity. By the lower die for the novel cast-aluminum rotor die-casting mold, the problem of cracking of the mold can be solved, and the service life of the mold can be prolonged.
Description
Technical field
The utility model relates to a kind of cast-aluminum rotor compression mod counterdie.
Background technology
Conventional cast-aluminum rotor compression mod advances aluminium from the fan blade and the balance columns of rotor self, and the counterdie level withdraws from and cuts clout simultaneously, and mould structure is simple, and technology is prone to row.But adopt this structure die casting counterdie easy to crack for the thin product of aluminium end ring, die life is very low, and serious situation is produced several moulds and the pressure break phenomenon just occurred.
The utility model content
The purpose of the utility model provides a kind of mould cracking problem, novel cast-aluminum rotor compression mod counterdie that prolongs die life of solving.
For realizing above-mentioned purpose, the utility model adopts following technical scheme: a kind of novel cast-aluminum rotor compression mod counterdie comprises lower mold body; Lower mold body is fixedly arranged in the counterdie overcoat; Lower mold body and counterdie overcoat all are arranged on the backing plate, and lower mold body is provided with the annular die cavity of corresponding cast-aluminum rotor, and counterdie is provided with the sprue that runs through backing plate and lower mold body; Lower mold body is provided with cross gate and ingate, and sprue is connected with annular die cavity through cross gate and ingate successively; Sprue and annular die cavity concentric.
Cross gate is uniformly distributed with around the sprue border and is provided with a plurality ofly, and ingate is positioned at the end of each cross gate.
The described novel cast-aluminum rotor compression mod counterdie of the utility model; Changed and advanced constructed of aluminium; Advancing aluminium by original fan blade and balance columns from rotor self is improved to the sprue that is provided with by the counterdie middle part and advances aluminium to annular die cavity; The counterdie bottom can thicken backing plate increases mould strength greatly, has solved mould cracking problem fully.
