Abstract
The invention discloses a direct casting technology for a pure aluminum metal mold. The technology comprises steps as follows: molten aluminum is prepared, a mold is prepared, preheated, mounted, cast, cooled and opened, and a cast is cleaned. Compared with a sand casting technology and a metal mold casting technology, the direct casting technology has the advantages that the material loss caused by secondary smelting is reduced, the production efficiency of castings is increased by 5-10 times, and meanwhile, the quality of casting products is further improved.
Description
Technical field
The present invention relates to pure aluminum metal die casting technical field, the straight pouring technique of more particularly, to a kind of pure aluminum metal mould.
Background technology
Sand casting process when casting fine aluminium, need feeding additional one and product more almost equal than arranging rising head,
The loss of the material of secondary smelting therefore can be caused larger, and metal die casting down gate feeding used, because down gate
Smaller, not resulting in secondary smelting has larger loss.
Content of the invention
The invention aims to shortcoming present in solution prior art, and a kind of pure aluminum metal mould proposing is straight
Pouring technique.
To achieve these goals, present invention employs following technical scheme：
Design a kind of straight pouring technique of pure aluminum metal mould, comprise the following steps：
S1：Preparation aluminium liquid, pure aluminum material is put in smelting furnace and is fused into liquid, the temperature control in smelting furnace is in 750-830
DEG C, then it is stand-by to obtain aluminium liquid by aluminium liquid treatment process；
S2：Mould prepares, and opens mould, uniform application releasing agent in the die cavity of mould, and the thickness of releasing agent will control
0.05-0.08mm；
S3：Mould preheats, and the mould having smeared releasing agent is placed in die heater, and mould is integrally preheated to 100- in S2
200℃；
S4：Mould installion, preheated mould in S3 is taken out by industry mechanical arm, and preheated mould installion is being poured
On casting machine；
S5：Die casting, by the aluminium liquid preparing in S1 in the stalk press-in metal casting mould on casting machine, and pours
The speed of cast aluminium liquid is slower, and the temperature of its casting is 750-815 DEG C；
S6：Cooling die sinking, after the completion of casting, should be lowered the temperature mould with water in time, when the aluminium liquid of the pouring of metal die, rising head is cold
When being but frozen into solid-state, stop being water-cooled, open mould afterwards and take out fine aluminium foundry goods；
S7：Casting cleaning, the pouring of the cast product taking out in S6, rising head are removed, and are polished in the surface of fine aluminium foundry goods
Process.
Preferably, the minimum high temperature resistant temperature of described high-temperature-resistant glove is 300 DEG C.
Preferably, the formula of described releasing agent is made up of zinc oxide, sodium metasilicate and water, and its ratio of components is classified as 5:0.8:
100.
Preferably, the material of described metal die is No. 45 steel.
A kind of straight pouring technique of pure aluminum metal mould proposed by the present invention, has the beneficial effects that：Pure aluminum metal mould directly pours work
Skill, for sand casting process and metal grinding tool casting technique, not only reduces the loss to material for the secondary smelting, also
Make the production efficiency of foundry goods improve 5-10 times, also improve the quality of cast product simultaneously.
