Description
Technical field
A kind of aluminum alloy low-pressure casting technical field is the utility model is related to, more particularly to a kind of aluminum alloy low-pressure casting
Venting plug.
Background technology
Aluminum alloy metal-type low-pressure casting has been used widely in China, and the exhaust of metal-mold low-pressure casting is casting
During one of key, in die cavity gaseous state change has a great impact to casting shaping, aluminium liquid is injected by stalk
When to metal mold cavity, the gas in die cavity must discharge rapidly, if discharging not in time, will be brought not to the quality of casting
Good influence.The venting plug blocking frequency is very high in production at present, and after blocking every time, die material need to be cooled to ability under normal temperature state
Dismounting, cleaning venting plug.After having cleared up venting plug, it must also reinstall and heat mould, take, consume energy, effort.
Utility model content
A purpose of the present utility model is to provide for a kind of durable, good exhaust effect, is not easily blocked, the aluminium conjunction that cost is low
Golden low pressure casting venting plug, to solve the problems mentioned in the above background technology.
Especially, the utility model provides a kind of aluminum alloy low-pressure casting venting plug, including exhaust stick harness, exhaust flange and
Some air discharge ducts；The exhaust flange has endoporus, and the exhaust stick harness is interference fitted with the endoporus；It is described exhaust stick harness be
Coniform cylinder, the air discharge duct be looped around in the shape of a spiral it is described exhaust stick harness inclined-plane it is cylindrical on, it is described exhaust stick harness include
First end and the second end, the diameter of the first end are less than the diameter at second end, the outer ring at the first end with it is described
Gas storage chamber is formed between exhaust flange, the first end top is provided with columned core vent cover.
Alternatively, the quantity of the air discharge duct is 15-22.
Alternatively, the air discharge duct is uniformly distributed on the inclined-plane of the exhaust stick harness is cylindrical.
Alternatively, the angle on the inclined-plane and the bottom surface at second end of the exhaust stick harness is 81-86 degree.
Alternatively, the diameter of the core vent cover is more than the diameter of the first end.
A kind of aluminum alloy low-pressure casting venting plug provided by the utility model, its aluminum alloy low-pressure casting exhaust flange are fixed on
On low pressure casting die, exhaust stick harness is in coniform, and exhaust stick harness inclined-plane is provided with numerous air discharge ducts circular in the shape of a spiral, is vented
Stick harness is interference fitted with exhaust flange endoporus.When aluminium liquid enters die cavity by stalk, with the entrance of the aluminium liquid in die cavity, die cavity
In gas gas storage chamber is entered by the air discharge duct being vented on stick harness inclined-plane, gas storage chamber is exhausted directly to outside low pressure casting die.When
After aluminium liquid is full of die cavity, because exhaust flange and venting plug are cone match, therefore narrow space can only accommodate less and thin aluminium liquid,
Thin aluminium liquid is cooled rapidly, become sticky, mobility is very poor, and prevents aluminium liquid and enter gas storage chamber.
A kind of aluminum alloy low-pressure casting venting plug provided by the utility model, its structure can ensure that aluminium liquid does not block exhaust seam
Gap, smooth in exhaust in casting process.Once mounting is realized, it is long-term use of, cleared up without midway.Maintained after only needing mould end
Cleaning.It is also extremely convenient to be changed after venting plug damage, thoroughly solve because venting plug blocks and caused by production interruption, stop
The problem of stagnant, production efficiency is substantially increased, reduce energy consumption, saved cost.
According to the accompanying drawings will be more to the detailed description of the utility model specific embodiment, those skilled in the art
Add clear of the present utility model above-mentioned and other purposes, advantages and features.
