Description
Technical field
This utility model belongs to casting device technical field and in particular to a kind of device for magnesium alloy fusible pattern.
Background technology
Magnesium alloy has that proportion is low, the high feature of specific strength, and its vibration damping and electromagnetic wave shielding are also more excellent, closely
Increasingly it is widely applied over year.The chemical property of magnesium is very active, easily occurs violent in the casting process of magnesium
Oxidizing fire, greatly hampers the yield rate of magnesium alloy investment casting, and when therefore preventing from pouring into a mould, the oxidizing fire of magnesium is always
The critical problem of impact magnesium alloy investment casting.
The protection of liquid magnesium mainly has two ways, i.e. flux protection and gas shield.Flux protection passes through low melting point
Halogen covers on Serum Magnesium surface, stops the contact with air for the magnesium, thus protecting magnesium alloy not oxidizing fire.But, due to molten
Agent is difficult to be kept completely separate with Serum Magnesium and leads to form flux in the melt and be mingled with, and greatly reduces the decay resistance of magnesium alloy
And mechanical property, therefore the production of high-quality magnesium alloy investment casting tends to adopt gas shield both at home and abroad at present.Gas
Protection Code is that protective gas is placed in around shell, makes magnesium liquid surface film structure become to cause using the product of gas and magnesium
Close, stop inner melt and the contact of oxygen from obtaining protection.
Protective gas wide variety of in magnesium industry is mainly co at present2And sf6Gas.In casting process, if gas
Body protection is not enough, will produce burning point on magnesium liquid surface.These burning points will become the source of burning, even if in foundry goods table
There is dense film to generate during the solidification of face, still may proceed to burn.Therefore, in casting process, gas shield is important.
Chinese patent notification number cn201220086651.3, entitled: a kind of magnesium alloy investment casting gas shield device,

Top be provided with cast gate, the top of described container and upper cover seal cooperation.
Further, described shell assembly also includes running channel main channel, running channel branch road, formwork die cavity and shunting guided plate,
Multiple formwork die cavities are distributed in running channel main channel both sides symmetrical, and are connected with running channel main channel by running channel branch road；
The porch of the neighbouring running channel main channel in described running channel branch road is provided with shunting guided plate, and the bottom of shunting guided plate is connected to pours
The entry bottom of road main channel, and shunt the overall central authorities' inclination to running channel main channel of guided plate.
Further, the outlet in described running channel branch road is communicated with formwork die cavity upper corners.
Further, the channel width of described running channel main channel is reduced gradually downward by described cast gate, facilitates magnesium alloy liquation
Flow in formwork die cavity.
Further, the central axis in described running channel branch road and the central axis angle of running channel main channel are 60-80 °.
Further, described shunting guided plate and the angle of the central axis of running channel main channel are 10-20 °.
The operating process of this dress transposition comprises the following steps:
1. open lid, the shell after preheating is put in container, close and close lid.
2. open the air outlet valve of feeder, from the passage of lower vessel portion to container in blow protective gas, protective gas
Flow and time determined with specific size by the breathability of shell.
3. close feeder, open the air inlet of container.
4. magnesium alloy liquation is poured into by shell cast gate, and see whether to pour completely.
5., after the solidification of magnesium alloy liquation, open lid, take out the shell with foundry goods, clean out foundry goods.
Advantage of the present utility model and beneficial effect are: (1) multiple formwork die cavity is distributed in running channel main channel both sides right
Claim distribution, product can be obtained in batches, shorten the duration of pouring simultaneously, greatly reduce the consumption of magnesium alloy liquation, reduce
The past intensity of workman, product success rate is high；(2) top of the upper end of described shell assembly is provided with cast gate, described container
Top and the cooperation of upper cover seal, production equipment is simple, and equipment cost is low；(3) channel width of running channel main channel is poured by described
Mouth reduces gradually downward, and the porch of the neighbouring running channel main channel in described running channel branch road is provided with shunting guided plate, and shunting is drawn
The overall central authorities' inclination to running channel main channel of guide plate, running channel branch road forms angle with running channel main channel, facilitates magnesium alloy liquation
Uniformly flow rapidly into formwork die cavity, reduce the duration of pouring, make each running channel branch road and pressure equilibrium suffered by running channel main channel, with
When avoid occurring as soon as the phenomenon of solidification in casting process because of alloy molten solution.
