Description
Technical field
The utility model relates to casting technology field, especially a kind of new-energy automobile aluminium alloy electric motivation outer cover metal type
Low pressure casting die.
Background technique
Cast aluminium alloy gold motor casing is the important component of new-energy automobile driving motor, outside aluminium alloy electric motivation
Shell is the complex casting of aluminium alloy thin-walled structure, occurs shrinkage porosite repeatedly in production process, chokes with resentment, do not cast, cold shut etc.
Defect, and high production cost, production efficiency are low, are unable to satisfy the characteristics of high-volume is supplied.
Summary of the invention
Good, production efficiency that the purpose of the utility model is to provide a kind of exhaust performances and the high new-energy automobile aluminium of qualification rate
Alloy motor casing metal-mold low-pressure casting mold.
The utility model is realized in this way it includes upper chuck, preceding swage, rear swage, right swage, Zuo Tiemo, lower folder
Disk, helix core, gas vent, is vented logical, ingate, chill and sprue at sand core, exists it is characterized in that: sand core and helix core are arranged
On lower chuck, helix core is matched with preceding swage, rear swage, right swage, Zuo Tiemo, preceding swage, rear swage, Zuo Tiemo, right iron
Mould and sand core cooperatively form type chamber, and sand core internal is disposed with exhaust passage everywhere, and sand core surrounding is uniformly distributed four blocks of chills and four
Ingate is arranged, sand core internal is provided with sprue, is respectively arranged with exhaust on preceding swage, rear swage, Zuo Tiemo, right swage
Hole is provided with four gas vents on upper chuck.
The utility model has the beneficial effects that by take everywhere gas vent with outside vaccum-pumping equipment connect, pass through row
Gas channel vacuumizes to reduce and got angry inside precoated sand to defect caused by casting, and casting solidification sequence is adjusted by chill,
Good to improve cast(ing) surface, internal soundness, casting method manipulation is simple, and casting qualified rate can reach 95% or more.
Detailed description of the invention
The utility model is further described below in conjunction with attached drawing:
Fig. 1 is the structural schematic diagram of new-energy automobile aluminium alloy electric motivation outer cover metal type low pressure casting die；
Fig. 2 is the expanded view of new-energy automobile aluminium alloy electric motivation outer cover metal type low pressure casting die.
Specific embodiment
As shown in Figs. 1-2, which includes upper chuck
1, preceding swage 2, rear swage 3, right swage 4, Zuo Tiemo 5, lower chuck 6, sand core 8, helix core 9, gas vent 10, exhaust passage 11,
Ingate 12, chill 13 and sprue 14 are put it is characterized in that: sand core 8 and helix core 9 are placed on lower chuck 6 in cast-internal
The helix core 9 set is matched with preceding swage 2, rear swage 3, right swage 4, Zuo Tiemo 5, preceding swage 2, rear swage 3, Zuo Tiemo 5, the right side
Swage 4 and sand core 8 cooperatively form type chamber, arrange exhaust logical 11 everywhere inside sand core 8,8 surrounding of sand core be uniformly distributed four pieces it is cold
Iron 13 and four row's ingates 12, sand core 8 are internally provided with sprue 14, in preceding swage 2, rear swage 3, Zuo Tiemo 5, right swage 4
On be respectively arranged with gas vent 10, on upper chuck 1 be provided with four gas vents 10.
Its working principle is that: chuck 1 in preheating, preceding swage 2, rear swage 3, right swage 4, Zuo Tiemo 5, lower chuck 6, by sand
After core 8 and helix core 9 are placed in lower 6 designated position of chuck, with the open-and-close mechanism of low-pressure die casting plant by upper chuck 1, preceding swage
2, rear swage 3, right swage 4, Zuo Tiemo 5 carries out filling type after molding, and molten aluminum passes sequentially through sprue 14, interior under pressure
Running channel 12 carries out filling type into type chamber 7.Casting carries out vacuumizing and exhausting simultaneously, by gas vent 10, exhaust passage 11, by cold
Iron 13 reconciles solidification sequence, is opened after air injection machine pressure keeps to molten aluminum solidifying completely, takes out casting.
